A built-in battery pack is disposed inside the autonomous lawnmower. The battery pack is fastened inside the autonomous lawnmower and cannot be manually detached. It is necessary to use a tool to remove a screw or the like to mount or detach the battery pack. The autonomous lawnmower can automatically perform a work task without manual supervision. When there is insufficient power, the autonomous lawnmower automatically returns to the charging station to supply power to an energy module to for charging. Such a built-in battery pack is usually specially configured for a corresponding autonomous lawnmower and can be directly used after mounting.
Other electric tools such as a gun drill, a hammer drill, a trimmer, and a hand-propelled lawnmower are powered by a detachable battery pack. When an electric tool runs out of power, a user has to replace the battery pack with a backup battery pack.

For fastening manners, one end of the protection apparatus 12 is nondetachably fastened, and the other end of the protection apparatus 12 is detachably fastened, or both ends of the protection apparatus 12 are detachably fastened. “Detachable fastening” means that the protection apparatus 12 can be detached from the body 10 without a damaging act and without needing to detach a fastener such as a screw, and after being detached, the protection apparatus 12 can be fastened to the body 10 again. For example, a buckle is used. In contrast, “nondetachable fastening” means that the protection apparatus 12 can be detached from the body 10 only by using a damaging act or detaching a fastener such as a screw. For example, a nondetachable rotating shaft is used for fastening. In another embodiment, both ends of the protection apparatus 12 may be fastened, and both ends of the protection apparatus 12 are nondetachably fastened to the body 10. Specifically, the protection apparatus 12 and the body 10 define one accommodating cavity. The energy module 2 is completely accommodated inside the accommodating cavity to implement protection.

During charge of the energy module 2, the voltage conversion module 105 may recognize a voltage of a preconnected energy module 2 and convert the voltage into a charging voltage of the energy module, to store electrical energy in the energy module. The working voltage and the charging voltage are generally referred to as a corresponding standard voltage. For example, the charging voltage of the energy module 2 is a high voltage, and the charging station uses a low voltage to charge the energy module 2 or directly charge the energy module 2 by using the self-moving device 1. The voltage conversion module 105 converts the low voltage into the high voltage in a boosting manner to charge the energy module 2. The voltage conversion module 105 may be separately disposed in the self-moving device 1 or may be separately disposed in the energy module 2 or may be integrated in the control module 7 as some functions of the control module 7 or may be disposed in another position or in another form according to an actual case.
In this embodiment, because the self-moving device 1 is in an outdoor working environment and is prone to theft, the energy module 2 is usually fixedly disposed below the self-moving device 1. However, in this embodiment, the energy module 2 is selectively configured to power another electric tool 9. If the energy module 2 is fixedly disposed below the self-moving device 1, it is inconvenient for a user to rapidly fetch and mount the energy module 2, resulting in degraded user experience. Therefore, it is necessary to design an automatic working system that can make it convenient for the user to rapidly fetch and mount the energy module 2 and can prevent the energy module 2 or the self-moving device 1 from being stolen.

In another embodiment, the self-moving device 200 includes an anti-theft detection module 242, a control module 7, and an anti-theft system. The anti-theft detection module 242 is configured to detect related information of the energy module 2 and obtain a detection result. The control module 7 controls, according to the detection result, whether the anti-theft system is turned on. Specifically, in a specific embodiment, the anti-theft detection module 242 includes a signal transmitter disposed on the self-moving device 200 and a signal receiver disposed in the energy module 2. A signal strength range is preset. If signal strength received by the signal receiver is less than the preset signal strength range, the control module controls the anti-theft system to be turned on. In another specific embodiment, the anti-theft detection module 242 includes a coordinate positioning module, for example, a GPS positioning module, configured to position the energy module 2 and acquire the position information of the energy module 2. A safe position range is preset. When the position of the energy module 2 acquired by the coordinate positioning module is beyond the safe position range, the control module 7 controls the anti-theft system to be turned on. In an embodiment, the anti-theft system includes a terminal device such as a mobile phone or a computer that can be connected to the coordinate positioning module through wireless communication.

A user may find the energy module 2 according to the position information sent by the coordinate positioning module.
In another embodiment, the anti-theft system is an alarm apparatus. When the anti-theft system is turned on, it means that when the anti-theft detection module 242 detects that the energy module 2 is abnormally unplugged, the control module 7 controls the alarm apparatus to raise an alarm. An alarm manner may be light, sound or the like. Alternatively, alarm information or the like may be automatically sent to a terminal device such as a user's mobile phone or another movable device. In another embodiment, the anti-theft system includes a management system for managing whether the energy module sleeps. When the anti-theft system is turned on, it means that when the anti-theft detection module 242 detects that the energy module 2 is abnormally unplugged, the management system manages the sleep of the energy module 2. When the energy module 2 sleeps, it means that the energy module 2 is locked and enters a fake-death state. Even if the energy module 2 is stolen, the energy module 2 cannot continue to work and can be used only after reactivation by the user.

The electric tool 9, the home appliance, and the like may be generally referred to as electric devices.
As shown in
The terminal 1022 is a common electrical conductor, including, but is not limited to, a metal conductor such as copper, iron, aluminum or silver. The shape of the terminal 1022 matches that of the docking terminals to perform insertion type electrical connection. The shape of the terminal 1022 may be a sheet-shaped, rod-shaped or similar plug-type protrusion. A corresponding docking terminal is disposed in a concave groove to form a receptacle. The terminal 1022 may be disposed in the concave groove to form the receptacle, and a corresponding docking terminal is disposed as a plug-type protrusion. The terminal 1022 may be a two-phase or three-phase plug or a multi-phase plug.
In this embodiment, the terminal 1022 is movable relative to the body 210, so that when the terminal 1022 is electrically connected to the docking terminal, the terminal 1022 is movable along with the docking terminal. It needs to be understood that the self-moving device 200 usually bumps over and shakes during movement, and the machine intensely sways during working, resulting in shaking of a battery pack. The battery pack makes a relative displacement relative to the body 210. In the conventional self-moving device 200, a plug terminal with a lead is disposed on the battery pack, and is docked to a receptacle terminal on the self-moving device 200 to implement an electrical connection. When the battery pack makes a relative displacement relative to the body 210, with the presence of the lead, the plug terminal and the receptacle terminal do not move relatively. In an embodiment of the present invention, the self-moving device 200 and the battery pack are directly docked in the form of a connector, to implement fast plug of the battery pack for selective use in another electric device. If a conventional design is used, a connector is fixed in the body 210. When a battery pack makes a relative displacement relative to the body 210, the terminal 1022 and a docking terminal in the battery pack have frequent relative movements, and an electrical spark is highly likely to occur. In a general concept, the fixation of a battery pack is strengthened, thereby reducing a relative displacement between a terminal and a docking terminal. In the technical solution in this implementation, the convention is broken to degrade the fixation of the terminal 1022, to enable the terminal 1022 to move relative to the body 210. With this design, when a battery pack moves relative to the body 210, the terminal 1022 is driven to move relative to the body 210, thereby avoiding an electrical spark generated from frequent relative movements between the docking terminal on the battery pack and the terminal 1022.
In a specific embodiment, the connector 102 is suspended in the body 210. Specifically, the body 1023 of the connector 102 is suspended on the wall portion 204 in the body 210. In this embodiment, the wall portion 204 is a part of the body 210. Specifically, as shown in
As shown in
In this embodiment, there is a gap between the restricting portion 1026 and the connecting portion 1025, to enable the two to move relative to each other. As shown in
In another embodiment, there may be gaps between the connecting portion 1025 and the restricting portion 1026 in only some directions rather than all the directions according to an actual case. In this embodiment, as shown in
In another embodiment, at least one of the restricting portion 1026 and the connecting portion 1025 is an elastic body that can elastically deform, and no gap may be provided between the two. For example, the restricting portion 1026 is an elastic body. When the battery pack shakes, the connecting portion 1025 shakes along. Because the restricting portion 1026 is an elastic body and has a particular compression space. The connecting portion 1025 can still move relative to the body 210 in a particular range. In this embodiment, the connecting portion 1025 may be disposed as an elastic body. When the battery pack shakes, the connecting portion 1025 shakes along. Because the connecting portion 1025 is an elastic body and has a particular compression space, the terminal 1022 can still move relative to the body 210 in a particular range. In this embodiment, both the connecting portion 1025 and the restricting portion 1026 may be disposed as elastic bodies. Certainly, in this embodiment, a gap may be provided between the restricting portion 1026 and the connecting portion 1025, to increase a suspension space of the terminal 1022.
In another embodiment, the body 210 further includes an elastic component (not shown) disposed between the restricting portion 1026 and the connecting portion 1025. When a battery pack shakes, the elastic component is compressed in a corresponding direction to form a corresponding suspension space, to enable the terminal 1022 to move relative to the body 210.
In an embodiment of the present invention, as shown in
In a specific embodiment, the self-moving device 1 further includes a storage unit 16 configured to store customized information and a control module 7 for controlling the self-moving device 1 to move and work. The customized information includes a time setting, a working time table, a login password setting, a speech setting, and the like. The working time table is a working time plan of the self-moving device 1. For example, a week is used as a unit, and the working time is 8:00 to 18:00 every day from Monday to Friday. In an embodiment, the main energy module 151 is unplugged at 10:00 on a Wednesday and the power is turned off for two hours. After the main energy module 151 is unplugged, the clock module 15 is powered by the backup energy module 152 to continue to record the real-time time of the self-moving device 1. When the main energy module 151 is inserted again to power the self-moving device 1, the time recorded by the clock module 15 is not reset, and the two hours during which the self-moving device 1 is powered off is automatically added to stick to the time setting of the self-moving device 1. In this embodiment, the control module 7 automatically controls the working time of the self-moving device 1 according to the time recorded by the clock module 15 and a preset working time table. Specifically, the control module 7 automatically adds two hours during which the self-moving device 1 is powered off, extends the working time of the self-moving device 1, and controls the self-moving device 1 to work 10:00 on the current day.
In another specific embodiment, after being unplugged, the main energy module 151 is configured to power another electric tool. When the main energy module 151 is inserted again, a battery level of the main energy module 151 is reduced compared with a battery level of the main energy module 151 when the main energy module 151 is unplugged. A difference between a remaining battery level when the main energy module 151 is unplugged and a remaining battery level when the main energy module 151 is inserted again may be used to calculate a charging time required to charge the battery level of the main energy module 151 to the remaining battery level when the main energy module 151 is unplugged, that is, a charging time required for the battery level of the main energy module 151 lost within the period of time during which the main energy module 151 is unplugged, so as to estimate a working end time according to the charging time for the lost battery level. For example, a week is used as a unit, and the working time is 8:00 to 18:00 every day from Monday to Friday. When the main energy module 151 is unplugged at 10:00 on a Wednesday and the power is turned off for two hours. In this case, when the energy module is inserted again to power the self-moving device, the two hours during which the main energy module 151 is powered off needs to be added. That is, the self-moving device works till 20:00 on the current day. If the remaining battery level of the main energy module 151 is 50% when being unplugged, and the remaining battery level of the main energy module 151 when the main energy module 151 is inserted again is 20%, in the working plan on the current day, the battery level of the main energy module 151 is reduced by 30% within a period of time during which the main energy module 151 is unplugged, and the time for charging of the 30% of the battery level needs to be added before the working plan on the current day can be completed. The control module 7 automatically controls the working time of the self-moving device 1 according to the time recorded by the clock module 15, the remaining battery level of the main energy module 151 when the main energy module 151 is unplugged, and the remaining battery level of the main energy module 151 when the main energy module 151 is inserted again. For example, if it takes one hour to charge the main energy module 151 from the remaining battery level of 20% to 50%, correspondingly, after the energy module is inserted again, the working end time on the current day is delayed by one more hour, that is, the work ends at 21:00.
In this embodiment, in the self-moving device 1, the backup energy module 152 for powering the clock module 15 is disposed to enable the self-moving device 1 to still accurately record the time after the main energy module 151 is powered off. In an aspect, when the main energy module 151 is inserted again, the time of the self-moving device 1 is accurate. In another aspect, the control module 7 automatically controls the working time of the self-moving device 1 according to the time recorded by the clock module 15 in combination with the preset working time table, so as to adjust a working time plan of the self-moving device 1.
In an embodiment of the present invention, as shown in
In an embodiment, the intelligent management platform 510 includes an information acquisition module 511 and an intelligent control module 512. The information acquisition module 511 is configured to acquire related information of the energy module 2.

The related information of the energy module 2 in this embodiment includes related information of the energy module 2 and related information of a circuit in which the energy module 2 is located. Specifically, the related information includes whether the energy module 2 is present (that is, whether there is a vacancy), an electrical parameter of the energy module 2, an environmental parameter of the energy module 2, and the like. The electrical parameter of the energy module 2 includes an electrical parameter of the energy module 2 itself and an electrical parameter of the circuit in which the energy module 2 is located.

The status of the circuit includes states such as charging and discharging, sequential charging and discharging, series and parallel connection charging and discharging, and mutual charging between energy modules. The environmental parameter includes a temperature, a humidity or the like of the energy module 2. The information acquisition module 511 may directly acquire the related information of the energy module 2 in a manner of detection or may acquire the related information of the energy module 2 in a communication manner. Specifically, when the related information of the energy module 2 is acquired in a communication manner, the intelligent management platform 510 presets a storage module for storing the related information of the energy module 2. The storage module sends the related information of the energy module 2 to the information acquisition module 511 in a wireless communication manner or the like.
In another embodiment, the intelligent management platform 510 further includes a recognition module. The recognition module is configured to recognize a self-moving device or an electric device powered by the energy module 2 and acquire device information. The electric device is a device other than the self-moving device 1. The device information is information of the self-moving device or electric device powered by the energy module 2. For example, when the energy module 2 is configured to power the self-moving device, the recognition module is configured to detect the information of the self-moving device. When the energy module 2 is configured to power another electric device, for example, is configured to power the electric tool 9, the recognition module is configured to recognize the information of the electric tool 9. The device information is information related to the device powered by the energy module 2, for example, the type of the device powered by the energy module 2, the power of the device, a supply voltage required for the device, and the size of a battery interface on the device, and the like. Further, the intelligent control module 512 controls the status of the energy module 2 according to the device information and the related information of the energy module 2. In a specific embodiment, the intelligent management platform 510 may recognize the device information in the following manner. In an embodiment, one recognition electrode is added to an electrode base to be connected to a battery pack electrode plate. The battery pack uses the recognition electrode to recognize the device. The recognition electrode may also be referred to as the recognition module. In another embodiment, sensors such as Hall sensors or photoelectric switch sensors are used to recognize different devices. Sensors mounted at different positions are used to recognize different device. For example, a sensor corresponding to a first tool is mounted at a first position, and a sensor corresponding to a second tool is mounted at a second position. The battery pack separately corresponds to the sensor in the first or second position to recognize a tool. For example, the first tool is determined if the first position is sensed, and the sensor may also be referred to as the recognition module. In another embodiment, reed switches are used to recognize different devices. A magnetic component is mounted at a battery pack. Reed switches are mounted at different positions of different tools. When there is magnetic inductance, two contacts of a reed switch are closed, so as to recognize different tools. The reed switch may also be referred to as the recognition module. In another embodiment, resistors are used to recognize different devices. One recognition resistor is provided inside the battery pack. There is also one recognition resistor inside the device. Voltage-division sampling is performed to recognize a resistance. Different devices have different resistances, so that different sampling voltages of different devices are detected, and a connected device is determined according to a corresponding sampling voltage. The recognition resistor may also be referred to as the recognition module. In the foregoing embodiments, the device includes a self-moving device and an electric device powered by the energy module 2. In other embodiments, the recognition module may be alternatively in another form, provided that the function of recognizing the device information can be implemented. The foregoing embodiments is only an example for description. In other embodiments, the related information of the energy module 2 may be recognized in the foregoing manners. The recognition module configured to recognize the related information of the energy module may also be referred to as an energy information acquisition module.
In a specific embodiment, the information acquisition module 511 include an electrical acquisition module 5111 and a temperature and humidity acquisition module 5112. Certainly, in other embodiments, the information acquisition module 511 may alternatively include only one of the electrical acquisition module 5111 and the temperature and humidity acquisition module 5112. The temperature and humidity acquisition module 5112 acquires one or two of the temperature and humidity of the energy module 2. Specifically, the temperature and humidity acquisition module 5112 performs detection to acquire one or two of the temperature and humidity of the energy module 2. The detecting the temperature or humidity of the energy module 2 herein includes directly or indirectly detecting the temperature or humidity of the energy module 2. The indirect detection is detecting the temperature, humidity or the like of the environment in which the energy module 2 is located to detect the temperature or humidity of the energy module 2. The temperature and humidity acquisition module 5112 acquires the temperature or humidity of the energy module 2. The intelligent control module 512 controls the status of the energy module 2 according to the temperature or humidity. For example, when the temperature is beyond a preset range, the energy module 2 does not work, or when the temperature is beyond a preset range, the energy module 2 cannot be used to charge another energy module, or when the temperature is beyond a preset range, the energy module 2 cannot be charged. When the temperature is high, a fan may be turned on or another cooling material may be used for cooling. When the humidity is beyond a preset range, the energy module 2 does not work.
Specifically, for a manner in which the intelligent control module 512 controls the status of the energy module 2 according to a detection result of the temperature and humidity acquisition module 5112, reference may be made to the following implementations.
In an example embodiment, as shown in

As shown in
In the foregoing embodiments, for example, the self-moving device is a robotic lawnmower. In other embodiments, the self-moving device may be an automatic leaf blower, an automatic water sprinkler, a multifunctional machine, an automatic snowplow, a robot cleaner or the like. As shown in
In another specific implementation, the intelligent control module 512 may further control a charging and discharging order of the energy module 2 according to the detected temperature and humidity. For example, the automatic working system 500 includes two energy modules 2. The temperature of one energy module 2 is relatively high. In this case, the intelligent management platform 510 intelligently manages that the other energy module 2 having a relatively low temperature is preferentially charged or discharged, and the original energy module 2 having a relatively high temperature is charged or discharged after being cooled.
For a specific manner in which the intelligent control module 512 controls the status of the energy module 2, reference may further be made to the following implementation:
In a specific implementation, the automatic working system 500 includes at least two energy modules 2. The information acquisition module 511 acquires the related information of the energy modules 2. The intelligent control module 512 controls a charging and discharging manner of the energy modules 2 according to the related information. The charging and discharging manner includes: the at least two energy modules 2 are sequentially charged or discharged, the at least two energy modules 2 are connected in series or parallel before charging or discharging, the at least two energy modules 2 are mutually charged before charging or discharging, and the like. For example, if the automatic working system 500 includes two energy modules 2, each energy module 2 is one battery pack. That is, the automatic working system 500 includes two battery packs. The two battery packs both have a voltage of 20 V. In this case, if a nominal voltage of the self-moving device 1 is 20 V, the intelligent control module 512 controls the energy modules to be connected in parallel to supply power. If the nominal voltage of the self-moving device 1 is 40 V, the intelligent control module 512 controls the energy modules 2 to be connected in series to supply power.
In another specific implementation, the automatic working system 500 includes at least two energy modules 2. The intelligent control module 512 controls, according to the related information acquired by the information acquisition module 511, the energy modules 2 to be sequentially charged or discharged and determine an order of sequential charging or discharging of the energy modules 2. Further, in an example embodiment, the information acquisition module 511 acquires the related information of the energy module 2. The intelligent control module controls, according to the related information, the energy modules 2 to be sequentially charged, to be connected in parallel to be charged or to be alternately charged, and the like. Further, in an example embodiment, the automatic working system 500 further includes a preference order management module 516 configured to manage a charging or discharging order of the energy modules 2. The intelligent control module 512 controls, according to the related information, the preference order management module 516 to manage the charging or discharging order of the energy modules 2. Specifically, for example, the electrical acquisition module 5111 acquires the battery levels of the energy modules 2, and compares different battery levels of the energy modules 2, and the intelligent control module 512 controls the preference order management module 516 to manage the energy module 2 with a higher battery level to preferentially supply power.
In another specific implementation, the automatic working system 500 includes at least two energy modules 2. The intelligent control module 512 controls, according to the related information acquired by the information acquisition module 511, the energy modules 2 to be connected in series and parallel before charging or discharging. Further, in another specific embodiment, the automatic working system 500 at least includes two energy modules 2. The intelligent management platform 510 further includes a series and parallel connection adjustment module 514 for changing a series and parallel connection manner between the energy modules 2. The information acquisition module 511 acquires the electrical parameter of the energy module 2. The intelligent control module 512 controls the series and parallel connection adjustment module 514 according to the electrical parameter to adjust a series and parallel connection manner of the energy module 2. Further, in a specific embodiment, the intelligent control module 512 controls the series and parallel connection adjustment module 514 according to the related information acquired by the information acquisition module 511 to manage parallel charging or alternate charging of the energy modules 2. Specifically, safe ranges are preset. The electrical acquisition module 5111 acquires voltages and battery levels of the energy modules 2. If a voltage difference and a battery level difference between the energy modules 2 are both in the safe ranges, the intelligent control module 512 controls the series and parallel connection adjustment module 514 to manage the energy modules 2 to be connected in parallel before charging. Further, in a specific embodiment, safe ranges are preset. The electrical acquisition module 5111 acquires voltages and battery levels of the energy module 2. If the voltage difference and the battery level difference between the energy modules 2 are both in the safe ranges, the intelligent control module 512 controls the energy module 2 to be connected in parallel to supply power. If the voltage difference or the battery level difference between the energy modules 2 is not in the safe range, the energy modules 2 are controlled to be connected in series to supply power. The safe ranges are a voltage difference range and a battery level difference range that are obtained according to experiments and allow safe mutual charging of the energy modules 2. For example, it is safe for one battery pack of 20 V and another battery pack with a voltage difference within 7.5 V to perform mutual charging. Therefore, for the battery pack of 20 V, a range with a voltage difference less than 7.5 V is a safe range. Next, for example, for two battery packs of 20 V, the battery level of one battery pack is 0, and the battery levels of the other battery pack is 100%. The two battery packs can safely perform mutual charging. Therefore, a range of a battery level difference between the battery packs of 20 V less than 100% is a safe range. The foregoing is only an example. Different battery packs may have different safe ranges. The present invention is not limited to the foregoing specific range values. Further, in another specific embodiment, the automatic working system 500 includes at least three energy modules. The information acquisition module 511 acquires the related information of the energy module 2. The intelligent control module 512 controls, according to the related information, the energy modules 2 to be combined in series or parallel for charging or discharging. For example, each energy module is one battery pack. There are three battery packs of 20 V. A battery level of one battery pack is 100%, and battery levels of the other two battery packs are 50%. In this case, the intelligent control module 512 controls the two battery packs with the battery levels of 50% to be connected in parallel and then connected in series to the other battery pack with the battery level of 100%. In this way, the energy of all battery packs can be utilized to the maximum extent.
In another specific implementation, the automatic working system 500 includes at least two energy modules 2. The automatic working system 500 further includes a mutual charging management module 515. The mutual charging management module 515 is configured to manage whether the energy modules 2 perform mutual charging and a corresponding mutual charging manner. The information acquisition module 511 acquires the related information of the energy module 2. The intelligent control module 512 controls, according to the related information, the mutual charging management module 515 to manage whether the energy modules 2 perform mutual charging and a corresponding mutual charging manner. Further, in a specific embodiment, when the intelligent control module 512 controls, according to the related information acquired by the information acquisition module 511, the energy modules 2 to be completely connected in parallel or partially connected in parallel, the mutual charging management module 515 manages whether the energy modules 2 are connected in parallel to perform mutual charging and a corresponding mutual charging manner. For example, the automatic working system 500 includes two energy modules 2. Each energy module 2 is one battery pack of 20 V. That is, the automatic working system 500 includes two battery packs of 20 V. The battery levels of the two battery packs of 20 V are separately 80% and 40%. The intelligent control module 512 controls the mutual charging management module 515 to manage that the two battery packs are first connected in parallel to perform mutual charging, and when both the battery levels reach 60%, the two battery packs are then connected in series to supply power. In this way, it may be avoided that the electric power of the battery pack with the battery level of 40% in the series connection cannot be output in time. If there are at least two battery packs, it is determined, according to the related information of the detected battery packs, whether the battery packs first perform mutual charging. If a voltage difference, a battery level difference or the like between two battery packs is beyond a safe range and mutual charging may damage one of the battery packs, the intelligent control module 512 controls the mutual charging management module 515 to manage the battery packs not to perform mutual charging.
In another specific implementation, the intelligent management platform 510 further includes a voltage adjustment module 513 for adjusting the voltage of the energy module 2. The information acquisition module 511 acquires the electrical parameter of the energy module 2. The intelligent control module 512 controls, according to the electrical parameter, the voltage adjustment module 513 to adjust an output voltage of the energy module 2. In an example embodiment, the electrical acquisition module 5111 acquires the electrical parameter of the energy module 2. Specifically, the electrical acquisition module 5111 acquires the output voltage of the energy module 2 and the nominal voltage of the self-moving device 1. The nominal voltage of the self-moving device 1 is a voltage required for the self-moving device 1 to work. The intelligent control module 512 controls, according to the acquired output voltage, the voltage adjustment module 513 to adjust an actual output voltage of the energy module 2, to adjust the actual output voltage of the energy module 2 to the nominal voltage of the self-moving device 1. For example, the electrical acquisition module 5111 acquires that the output voltage of the energy module 2 is 26 V, and the voltage actually required for the circuit is 20 V, the intelligent control module 512 controls the voltage adjustment module 513 to reduce the output voltage of the energy module 2, to adjust the actual output voltage of the energy module 2 to 20 V.
In another specific implementation, the information acquisition module 511 acquires a battery level condition of each energy module 2. The intelligent control module 512 controls, according to the battery level condition, whether each energy module 2 works. For example, the automatic working system 500 includes three energy modules. Each energy module is one battery pack. A battery level of one of the three battery packs is 0, and the intelligent control module controls the battery pack with the battery level of 0 not to work.
In another specific implementation, the intelligent management platform 510 further includes a human-computer interaction module 517. The human-computer interaction module 517 is configured to transfer information between the energy module 2 and a user or between the self-moving device 1 and a user. Specifically, in an example embodiment, the human-computer interaction module 517 can obtain an instruction of the user in a manner such as prestored information or wireless communication. The intelligent control module 512 controls the status of the energy module 2 according to the information obtained by the human-computer interaction module 517. Specifically, in another embodiment, the human-computer interaction module 517 may send the status of the energy module 2 or the self-moving device 1 to the user in real time, or the intelligent control module 512 controls the human-computer interaction module 517 to selectively send the status of the energy module 2 or the self-moving device 1 to the user. Specifically, in an embodiment, the human-computer interaction module 517 includes a user setting interface. The user may directly use the interface to set that the energy module 2 executes different states in different periods of time or in different environments. In another embodiment, the human-computer interaction module 517 includes a wireless communication module. The user may communicate with the human-computer interaction module such as a mobile APP or Bluetooth by using a mobile apparatus. The user gives an instruction on the mobile apparatus and transfers the instruction to the human-computer interaction module 517 by using the wireless communication module. The intelligent control module 512 controls the status of the energy module 2 according to the instruction obtained by the human-computer interaction module. For example, the user may use the mobile APP to set a specific period of time for the energy module 2 to stop working and enter a sleep state. Alternatively, the intelligent control module 512 controls the human-computer interaction module 517 to send instant information of the energy module 2 or the self-moving device 1 to a mobile phone of the user.
In another specific implementation, as shown in
In the foregoing embodiments, the automatic working system 500 includes an information acquisition module 511 and an intelligent control module 512. The information acquisition module 511 acquires the related information of the energy module 2. The intelligent control module 512 controls the status of the energy module 2 according to the related information. In a specific embodiment, the energy module 2 is a battery pack. Specifically, one energy module 2 is one battery pack. The battery pack includes a self-moving device battery pack used on the self-moving device 1. The self-moving device battery pack is a battery pack on the self-moving device 1, and includes a battery pack newly inserted in the self-moving device, but does not include an unplugged battery pack. The information acquisition module 511 can acquire information about a change in a quantity or type of the self-moving device battery pack. The intelligent control module 512 controls the status of the self-moving device battery pack according to the information about the change.
In an embodiment, the automatic working system 500 includes a preset default program. When the quantity or type of the self-moving device battery pack changes, the intelligent control module 512 controls the status of the self-moving device battery pack according to the default program. Specifically, the default program includes a preset battery level threshold. When the quantity of the self-moving device battery packs is increased, the self-moving device battery pack includes an originally connected battery pack and a newly added battery pack. The originally connected battery pack is a battery pack that has originally been connected to the self-moving device when the quantity of the self-moving device battery packs is not increased. The newly added battery pack is a battery pack newly inserted in the self-moving device. The information acquisition module acquires a battery level of the newly added battery pack. The intelligent control module controls the status of the newly added battery pack according to a relationship between the battery level of the newly added battery pack and the battery level threshold. When the battery level is greater than the battery level threshold, the intelligent control module controls the newly added battery pack and the originally connected battery pack to be discharged together. When the battery level is not greater than the battery level threshold, the intelligent control module controls the newly added battery pack not to supply power. When the self-moving device returns to the charging station, the intelligent control module controls the newly added battery pack and the originally connected battery pack to be charged together. The “charged together” and “discharged together” mean that the newly added battery pack and the originally connected battery pack are simultaneously charged or discharged or are sequentially charged or discharged. Specifically, it is chosen that the newly added battery pack and the originally connected battery pack are simultaneously charged or discharged or are sequentially charged or discharged, a specific status of charging or discharging is selected. For example, in the case of sequential charging or discharging, a preference order is selected. In the case of simultaneous charging or discharging, for example, it is selected whether the self-moving device battery packs are connected in series or parallel, whether the self-moving device battery packs perform mutual charging, and whether the voltage needs to be increased. All these may be managed by the intelligent management platform according to the foregoing embodiments. The intelligent management platform intelligently manages a specific charging or discharging status of the newly added battery pack and the originally connected battery pack. When a total quantity of the self-moving device battery packs is not changed and only a battery pack is replaced with the same type of battery pack or another type of battery pack, the default program takes the newly inserted battery pack as the newly added battery pack and uses the default program in the foregoing embodiments to determine the status of the self-moving device battery pack.
Specifically, the default program further includes a preset battery pack working condition. When the quantity of the self-moving device battery packs is reduced, a remaining battery pack after the quantity of the self-moving device battery packs is reduced is referred to as a remaining battery pack. The information acquisition module 511 acquires related information of the remaining battery pack, the intelligent control module 512 controls the status of the remaining battery pack according to whether the related information of the remaining battery pack meets the preset battery pack working condition. Specifically, if the related information of the remaining battery pack meets the preset battery pack working condition, the remaining battery pack continues to supply power. If the related information of the remaining battery pack does not meet the preset battery pack working condition, the self-moving device returns for charging. Certainly, if the related information of the remaining battery pack does not meet the preset battery pack working condition, the self-moving device 1 may be controlled to stop in situ or stand by and wait for another time to charge the self-moving device 1 or use another manner to charge the self-moving device 1. When the related information of the remaining battery pack does not meet the preset battery pack working condition, the self-moving device returns for charging, including that the self-moving device automatically returns for charging, a user manually takes the self-moving device back to the charging station for charging, and the like. Specifically, the default program further includes a preset condition for a battery pack to automatically return for charging. The information acquisition module acquires whether the remaining battery pack satisfies the condition for automatic return for charging. If the preset condition for automatic return for charging is satisfied, the self-moving device automatically returns for charging. If the preset condition for automatic return for charging is not satisfied, for example, if a quantity of the remaining battery packs is zero or a voltage or a battery level of the remaining battery pack is insufficient, the self-moving device reminds the user. A manner in which the self-moving device reminds the user includes: raising an alarm, providing a reminder on an operation interface, using a manner such as wireless communication to send information indicating that the self-moving device cannot automatically return for charging to the user's mobile APP or the like.
When it is determined according to the default program that the remaining battery pack needs to be charged or discharged, the specific charging or discharging status of the remaining battery pack can still be managed by the intelligent management platform according to the foregoing embodiments. The intelligent management platform intelligently manages the specific charging or discharging status of the remaining battery pack. In this embodiment, the information acquisition module acquires information about a change in the quantity and type of the self-moving device battery packs, and inputs the information about the change into the default program. The intelligent control module 512 intelligently controls the status of the self-moving device battery pack according to the default program, to implement an intelligent self-moving device and automatic working system thereof.
In another embodiment, the automatic working system 500 may not include the default program, or a user does not select the default program. Instead, the human-computer interaction module is used to directly control the self-moving device 1 to perform an act. The human-computer interaction module 517 is configured to transfer information between the energy module 2 and the user or between the self-moving device 1 and the user. In this embodiment, the user uses the human-computer interaction module 517 to transfer an instruction of the user to the self-moving device 1. The intelligent control module 512 controls, according to the instruction of the user, the status of the energy module 2. Specifically, a user setting interface may be used to directly input the instruction of the user. The user setting interface includes buttons on the self-moving device 1, a mobile APP that can perform wireless communication with the self-moving device or the like. Specifically, some programs corresponding to the buttons or instructions on the mobile APP may be preset by using the self-moving device 1. For example, regardless of any factor, all the self-moving device battery packs are forcefully instructed to be discharged or charged or not to supply power together, or a designated self-moving device battery pack is forcefully instructed to be discharged or charged or not to supply power. When a corresponding instruction is given, the intelligent control module 512 controls a corresponding program to be turned on, and the self-moving device battery pack executes a corresponding state. In this embodiment, the information acquisition module 511 acquires the information about the change in the quantity and type of the self-moving device battery packs. The intelligent control module 512 intelligently controls the status of the self-moving device battery pack according to the information about the change, to implement an intelligent self-moving device and automatic working system thereof.
In a specific embodiment, when a battery pack is inserted in or unplugged from the self-moving device 1, the information acquisition module 511 acquires related information of the self-moving device battery pack, and the intelligent control module 512 intelligently controls the status of the self-moving device battery pack according to the related information. Specifically, when a battery pack is inserted into or unplugged from the self-moving device 1, the information acquisition module 511 acquires the information about the change in the quantity or type of the self-moving device battery packs, to make it convenient to directly use the default program to control an initial status of the self-moving device battery pack. In addition, the information acquisition module further acquires other related information such as an electrical parameter, a temperature or a humidity of the self-moving device battery pack, and the intelligent management platform 510 is used to further confirm a further status of the self-moving device battery pack. In this embodiment, when a battery pack is inserted into or unplugged from the self-moving device, the self-moving device uses the default program to control the initial status of the self-moving device battery pack, and the intelligent management platform 510 is combined to further confirm a specific status of the self-moving device battery pack, to eventually intelligently control the status of the self-moving device battery pack when a battery pack is plugged into or unplugged from the self-moving device.
In an implementation of the present invention, as shown in

In an embodiment, the charging system 810 includes at least two charging modes. Each charging mode is used to match one of at least two different types of energy modules 2, to enable the charging system 810 to use a corresponding charging mode to charge the at least two different types of energy modules 2. Different types of energy modules 2 are categorized according to at least one manner of a manufacturer, a model, a used material, a shape, a size, a capacity, a cell type, a structure, and the like. The energy modules 2 have different types. For example, in the two energy modules 2, one cell is produced by Samsung, and the other cell is produced by Sony. It is therefore considered that the two energy modules 2 have different types. For another example, in the two energy modules 2, one is 1P, and the other is 2P. It is also considered that the two energy modules 2 have different types. For another example, in the two energy modules 2, one has a full voltage of 20 V, and the other has a full voltage of 36 V. It is therefore considered that the two energy modules 2 have different types. In an embodiment, in the at least two charging modes, different charging parameters are separately used to charge the energy module 2, to enable the charging system 810 to use a corresponding charging parameter to charge the energy module 2, that is, enable the charging system 810 to select a suitable charging parameter to charge the energy module 2. For example, according to the full voltage of the energy module 2, a corresponding charging voltage for charging the energy module 2 is selected. Alternatively, a corresponding charging current for charging the energy module 2 is selected according to a maximum bearable charging current of the energy module 2. For example, when a battery pack has a higher capacity, a relatively high charging current may be selected to reduce a charging time for a high-capacity battery pack. Alternatively, a corresponding temperature range for normally charging the energy module 2 is selected according to the type of the energy module 2. Specifically, the corresponding temperature range may be selected according to a cell type of the energy module 2. For example, if a cell of the energy module 2 is from Samsung, the energy module 2 is controlled to be normally charged in a temperature range of 0° C. to 50° C., and charging stops when the temperature exceeds 50° C. If a cell of the energy module 2 is from Sony, the energy module 2 is controlled to be normally charged in a temperature range of 0° C. to 55° C., and charging stops when the temperature exceeds 55° C. Certainly, after the temperature range is selected according to the cell type of the energy module 2, the temperature range may further be selected according to the structure of the energy module 2. For example, if a cell of the energy module 2 is a Sony cell, the structure of the energy module 2 is further considered. Specifically, when the energy module 2 is a 2P battery pack, the energy module 2 is controlled to be normally charged in the temperature range of 0° C. to 55° C., and charging stops when the temperature exceeds 55° C. If the energy module 2 is a 1P battery pack, the energy module 2 is controlled to be normally charged in the temperature range of 0° C. to 50° C., and charging stops when the temperature exceeds 55° C. Certainly, the foregoing specific temperature restriction is only an example, and is specifically determined according to an actual case.
In another embodiment, the charging system 810 includes at least two energy modules 2 charged by a charging system. The charging system 810 includes at least two charging modes. Each charging mode uses one of at least two different charging orders to charge the energy module, to enable the charging system to use a corresponding charging order to charge the energy module. Specifically, the types of the charging order include sequential charging and an order of sequential charging, simultaneous charging and a manner of simultaneous charging (for example, series charging or parallel charging), a combination of sequential charging and partially simultaneous charging and a specific manner of combination (for example, for charging of three battery packs, one battery pack is charged first, and the remaining two battery packs are simultaneously charged), and the like. Certainly, the foregoing is only an example. A specific charging order may be set according to an actual case, and is not limited to the foregoing specific form.
In another embodiment, the charging system 810 may combine the foregoing two embodiments. That is, the charging system 810 includes two charging modes. Each charging mode is used to match one of the at least two different types of energy modules 2. The charging system 810 further includes two more charging modes. Each charging mode uses one of at least two different charging orders to charge the energy module.
In other embodiments, the charging system 810 may include other different charging modes. For example, each charging mode uses different charging logics for charging or each charging mode uses different charging parameters to perform charging, which is specifically set according to an actual case. Examples are not described one by one herein.
In this embodiment, when the self-moving device 800 is powered on or when a quantity of the energy modules 2 changes, the charging management module 801 automatically adjusts a charging mode of the charging system 810, so that when the charging system 810 is powered on or when the quantity of the energy modules 2 changes, a corresponding charging mode is automatically selected to charge the energy module. Certainly, in other embodiments, the charging management module 801 may also monitor the self-moving device 800 and the status of the energy module 2 in real time, to adjust the charging mode of the charging system in real time. Alternatively, a manner such as manual adjustment is used, so that the charging mode is manually adjusted at any time according to a user requirement.
Specifically, the charging management module 801 adjusts the charging mode in various manners, for example, an automatic adjustment manner or a manual adjustment manner.
As shown in
The energy module 2 includes an energy information providing module 280 configured to provide the related information of the energy module 2, and an energy information acquisition module 806 configured to acquire information provided by the energy information providing module 280. The energy information acquisition module 806 may recognize the energy information providing module 280 in the conventional recognition manner to acquire information provided by the energy information providing module 280. For example, an electrical connection manner is used to recognize the information provided by the energy information providing module 280 or a communication manner may be used to communicate with the energy information providing module 280 to acquire information provided by the energy information providing module 280.
In an implementation, the energy information acquisition module 806 recognizes related information of the energy module in the conventional recognition manner. Specifically, the energy information providing module 280 includes at least one of a recognition electrode, a sensor, a reed switch, a recognition resistor, and the like. Specifically, the related information of the energy module 2 may be recognized in the following manner. In an embodiment, one recognition electrode is added to the battery pack to be connected to an electrode of an electrode base. A recognition electrode on a battery pack is recognized to recognize related information of the battery pack. The recognition electrode may also be referred to as the energy information providing module 280. The energy information acquisition module 806 is located on the self-moving device and is configured to acquire the information provided by the energy information providing module 280. In another embodiment, sensors such as Hall sensors or photoelectric switch sensors may be used to recognize different battery packs, and sensors mounted at different positions to recognize different battery packs. For example, a sensor corresponding to a first battery pack is mounted at a first position, and a sensor corresponding to a second battery pack is mounted at a second position. The self-moving device separately senses a sensor corresponding to the first or second position to recognize a battery pack. For example, the first battery pack is determined when the first position is sensed. The foregoing sensor located on the battery pack may be referred to as the energy information providing module 280, and the energy information acquisition module 806 is located on the self-moving device and is configured to acquire the information provided by the energy information providing module 280. In another embodiment, reed switches are used to recognize different battery packs. A magnetic component is mounted on the electrode base. Reed switches are mounted at different positions of different battery packs. When there is magnetic inductance, two contacts of a reed switch are closed, so as to recognize different battery packs. The reed switch may also be referred to as the energy information providing module 280. The energy information acquisition module 806 is located on the self-moving device and is configured to acquire the information provided by the energy information providing module 280. In another embodiment, resistors are used to recognize different battery packs. One recognition resistor is provided inside the self-moving device 800. There is also one recognition resistor in the interior of the battery pack. Voltage-division sampling is performed to recognize a resistance. Different battery packs have different resistances, so that different sampling voltages of different battery packs are detected, and a connected battery pack is determined according to a corresponding sampling voltage. The recognition resistor may also be referred to as the energy information providing module 280. In the foregoing embodiments, the device includes a self-moving device and an electric device powered by the energy module 2. The energy information acquisition module 806 is located on the self-moving device and is configured to acquire information provided by the energy information providing module 280. In other embodiments, the energy information acquisition module 806 may be alternatively in another form, provided that the function of recognizing the device information can be implemented. The foregoing embodiments is only an example for description.
In another implementation, the energy information acquisition module 806 may also acquire related information of the energy module in a communication manner. Specifically, the energy information acquisition module 806 and the energy information providing module 280 may implement communication in a manner such as wired communication or wireless communication. The self-moving device 800 uses the energy information acquisition module 806 to communicate with the energy module 2, to acquire related information of the energy module 2. In this embodiment, a communication manner is used to acquire the related information of the energy module 2, so that the acquired information of the energy module 2 is more comprehensive, instead of recognizing only relatively simple information of the energy module 2. In this embodiment, in a communication manner, whether the energy module 2 exists (that is, whether there is a vacancy), a quantity, type information, an electrical parameter (for example, temperature information, voltage information, capacity information or battery level information) of the energy module 2, and the environmental parameter (for example, a temperature or a humidity of the energy module 2), and the like may be acquired, and in addition, information such as a delivery date, a repair condition, a use record of the energy module 2 may further be acquired, and other information stored in the energy module 2 may also be acquired, so that the information acquired by the self-moving device 800 is more complete and precise. After acquiring the related information of the energy module 2, the self-moving device 800 may further display the related information on a user interface or on another user terminal such as a user's mobile phone, a computer or a remote control that can communicate with the self-moving device 800. For example, the self-moving device 800 automatically acquires an electrical parameter, type information, environment information, quantity information, a repair condition, a use record, and the like of the energy module 2, and the related information is then sent to the user's mobile APP for the user to browse related conditions of the energy module 2. Specifically, in an embodiment, an information acquisition method may include the following steps: The self-moving device 800 is turned on and powered up. The self-moving device 800 and the energy module 2 use the energy information acquisition module 806 and the energy information providing module 280 to send handshake information and establish a communication connection. The control module 7 of the self-moving device 800 sends a data frame in a specific format. The energy module 2 uses a specific data frame to feed back the related information of the energy module. The control module 7 parses the data frame fed back by the energy module 2 to obtain the related information of the energy module 2 to perform various control of the entire machine or use the human-computer interaction module to present the related information to the user. Certainly, in other embodiments, another form may be used to implement communication. The foregoing specific embodiment is only an example.
In this embodiment, when the self-moving device 800 is powered on, the energy information acquisition module 806 automatically acquires at least one piece of quantity information and type information of the energy module 2. The control unit 808 controls, according to at least one piece of the quantity information and type information of the energy module 2, a charging mode for charging the energy module 2 by the charging system 810. That is, when the self-moving device 800 is powered on, the charging system 810 is controlled to automatically select a suitable charging mode to charge the energy module 2. After the self-moving device 800 is powered on, the energy information acquisition module 806 continuously acquires the quantity information of the energy module 2. When a quantity of the energy modules 2 changes, the charging management module 801 adjusts in real time a charging mode for charging the energy module 2. After a suitable charging mode is selected, the energy information acquisition module 806 continues to keep acquiring the related information of the energy module 2. For example, the energy information acquisition module 806 acquires one or more pieces of a quantity, a current temperature, a voltage value, a remaining battery level value, and the like of the energy module 2 in real time. The control unit 808 controls, according to the related information acquired by the energy information acquisition module 806, a charging status of charging the energy module 2 by the charging system 810. The charging status is at least one of whether charging is performed, a charging order, a charging current, a charging voltage, a charging power, a charging battery level, a charging time, and the like. That is, the energy information acquisition module 806 keeps acquiring a real-time status of the energy module 2. The control unit 808 controls in real time, according to the real-time status of the energy module 2, the charging status of charging the energy module 2 by the charging system 810, for example, controls whether to charge the energy module 2, and selects the magnitude of the charging current, charging voltage or charging power, a charging cutoff battery level, charging duration, and the like. Specifically, the charging management module further includes a charging status adjustment module 809 configured to adjust the charging status of the energy module 2. The control unit 808 controls, according to the related information of the energy module 2 acquired by the energy information acquisition module 806, the charging status adjustment module to adjust the charging status of the energy module 2. Specifically, the charging status adjustment module 809 includes at least one of a charging current adjustment module configured to adjust the charging current of the energy module 2, a charging battery level management module configured to adjust the charging battery level of the energy module 2, a charging power management module configured to adjust the charging power of the energy module 2, and the like.

For example, the energy information acquisition module 806 is configured to acquire a current voltage value of the energy module 2. The control unit 808 controls, according to the current voltage value of the energy module 2, the charging system 810 to select to use one of the constant current charging mode 831 and the constant voltage charging mode 832 to charge the energy module 2.

In an embodiment, the human-computer interaction module 807 adjusts a charging parameter and/or charging logic for charging the energy module 2 by the charging system 810, to adjust a charging mode. Specifically, the foregoing instruction includes an adjustment instruction for adjusting the charging parameter and/or charging logic for charging the energy module 2 by the charging system 810. The human-computer interaction module 807 is configured to send the adjustment instruction. The instruction receiving module 8015 is configured to receive the adjustment instruction. The control unit 808 adjusts, according to the adjustment instruction, the charging mode for charging the energy module 2 by the charging system. For example, a user uses a mobile APP to directly adjust the charging parameter for charging the energy module 2 by the charging system 810. For example, the mobile APP is used to directly set a charging current, a charging voltage, a charging cutoff temperature, a charging cutoff battery level, a charging time, and the like. The mobile APP sends an adjustment instruction for adjusting the charging current, the charging voltage, the charging cutoff temperature, the charging cutoff battery level, the charging time, and the like of the energy module 2. The instruction receiving module 8015 receives the adjustment instruction. Certainly, the mobile APP may be alternatively used to directly set and send the adjustment instruction for adjusting the charging logic. The instruction receiving module 8015 receives the adjustment instruction, for example, a charging order for adjusting the energy module 2. For example, there are a total of three battery packs. The mobile APP is used to directly adjust which of the three battery packs is charged first or charged next, series charging or parallel charging or the like. The human-computer interaction module may be used, and the adjustment instruction for adjusting the charging parameter and charging logic is simultaneously sent. The instruction receiving module 8015 receives the adjustment instruction. For example, there are a total of three battery packs. The mobile APP is directly used to adjust a charging parameter, charging order or the like corresponding to each battery pack. In an embodiment, for example, the human-computer interaction module 807 is used to set a charging cutoff battery level of each battery pack. The control unit 808 controls the charging system 810 to charge each battery pack and keeps detecting whether a current battery level of a battery pack is the same as a set battery level. If the current battery level is the same as the set battery level, the charging system 810 stops charging the current battery pack. Certainly, only an example in which the human-computer interaction module 807 is a mobile APP is used. In other embodiments, an operation may be alternatively performed on the user interface or another user terminal on the self-moving device 800.
In another embodiment, the human-computer interaction module 807 may alternatively directly adjust a charging mode in a manner of switching between preset charging modes. Specifically, the self-moving device 800 presets a plurality of preset charging modes for charging the energy module 2. An instruction sent by the human-computer interaction module 807 includes a switching instruction for switching between the preset charging modes. The instruction receiving module 8015 receives the switching instruction. The control unit 808 controls, according to the switching instruction, the charging system 810 to use a corresponding preset charging mode to charge the energy module 2. For example, a switching key for switching a charging mode is disposed on the user interface, a user's mobile APP or the like on the self-moving device 800. The user may use the switching key to manually switch between the preset charging modes.

Specifically, the scheduling module 8012 may preset, in a manner of preset timetable, to use a time arrangement of preset charging modes or may use a manner of memorizing a habit of a user to generate the timetable representing the time arrangement of the preset charging modes. In an embodiment, the scheduling module 8012 includes a preset timetable 8013 representing the time arrangement of using the preset charging modes by the charging system 810. The control unit 808 controls the charging system 810 to charge the energy module 2 according to the plan of the scheduling module 8012, to enable the charging system 810 to charge the energy module 2 according to a corresponding preset charging mode at a corresponding time. For example, when the self-moving device 800 is delivered from the factory, the timetable 8013 is preset according to a regular habit of the user obtained through statistics. The control unit 808 controls, according to the timetable 8013, the charging system 810 to charge a charging mode of the energy module 2. In another embodiment, the scheduling module 8012 is configured to memorize a habit of using the preset charging modes by the self-moving device 800, and generate, according to the memorized content, the timetable 8013 representing the time arrangement of using the preset charging modes by the charging system 810. The control unit 808 controls, according to the plan of the scheduling module, the charging system 810 to charge the energy module 2, to enable the charging system 810 to charge the energy module 2 according to a corresponding preset charging mode at a corresponding time. For example, the scheduling module 8012 automatically memorizes a use habit of the user in one month, that is, records, within one month, a time distribution of using the preset charging modes by the self-moving device 800, and automatically collects statistics to generate a corresponding pattern to form the timetable 8013. The control unit 808 automatically controls, according to the generated timetable 8013, the charging system 810 to charge the charging mode of the energy module 2, to enable the charging system 810 to charge the energy module 2 according to a corresponding preset charging mode at a corresponding time.
In another embodiment, the foregoing embodiments having the scheduling module 8012 may be combined with the embodiment having the human-computer interaction module 807. For example, the human-computer interaction module 807 is configured to send an instruction for representing the timetable 8013. The timetable is used to plan the charging system 810 to charge a time arrangement of the charging mode of the energy module 2. A user plans the time arrangement of the charging mode by using the human-computer interaction module 807. The scheduling module 8012 further includes an instruction receiving module. The instruction receiving module 8015 is configured to receive the foregoing instruction for representing the timetable. The control unit 808 is configured to control, according to the foregoing instruction, the charging system 810 to charge the charging mode of the energy module 2, to enable the charging system 810 to charge the energy module 2 at a corresponding time according to a corresponding preset charging mode set by the user.
In a specific embodiment, the self-moving device 800 presets a plurality of preset charging modes for charging the energy module 2. The control unit 808 is configured to control the charging system 810 to use a corresponding preset charging mode to charge the energy module 2.

The charging management module 801 is configured to control the charging system 810 to use a corresponding preset charging mode to charge the energy module 2. Specifically, the charging management module 801 may adjust the charging speed in several manners in the following.
In an implementation, the charging management module 801 may control a charging current for the charging system 810 to charge the energy module 2, to adjust the charging speed of the charging system 810. Specifically, both the fast-charging mode 833 and the slow-charging mode 834 include using a constant charging current to charge the constant current charging mode 831 of the energy module 2. In the constant current charging mode 831 in the fast-charging mode 833, the charging management module 801 increases the charging current for the charging system 810 to charge the energy module 2, to increase the charging speed of the charging system. That is, in the constant current charging mode 831 in the fast-charging mode 833, a charging current for charging the energy module 2 by the charging system 810 is greater than a charging current in the constant current charging mode 831 in the slow-charging mode 834, to increase the charging speed in the fast-charging mode 833.
The fast-charging mode 833 and/or the slow-charging mode 834 may include only the constant current charging mode 831, that is, only use the foregoing constant current mode to perform charging; or may include both the constant current charging mode 831 and the constant voltage charging mode 832, that is, use a manner combining the constant current charging mode 831 and the constant voltage charging mode 832 to perform charging. In other words, in a process of charging the energy module 2 having an insufficient battery level until the energy module 2 is fully charged, the fast-charging mode 833 and/or the slow-charging mode 834 separately includes a constant current charging stage of performing charging using the constant current charging mode 831 and a constant voltage charging stage of performing charging using the constant voltage charging mode 832. In the fast-charging mode 833 and/or the slow-charging mode 834, the charging management module 801 controls the charging system 810 to automatically select, according to the current voltage value of the energy module, to use the constant current charging mode 831 or the constant voltage charging mode 832 to charge the energy module 2. In this case, the fast-charging mode 833 and/or the slow-charging mode 834 increases a charging current thereof only in the constant current charging mode 831 thereof to increase the charging speed in the constant current charging mode 831. Certainly, in other embodiments, in the fast-charging mode 833 and/or the slow-charging mode 834, the charging speeds in the constant current charging mode 831 and the constant voltage charging mode 832 may both be increased, to increase the charging speed of charging the energy module 2 by the charging system 810.
Specifically, in an embodiment, the fast-charging mode 833 and the slow-charging mode 834 both have the foregoing constant current charging stage of performing charging using the constant current charging mode 831 and a constant voltage charging stage of performing charging using the constant voltage charging mode 832. The charging management module 801 controls the charging system 810 to automatically select, according to the current voltage value of the energy module, to use the constant current charging mode 831 or the constant voltage charging mode 832 to charge the energy module 2. With the same energy modules 2 charged by the charging system 810, for example, with the same type and quantity of the energy modules 2, a charging current of the constant current charging stage in the fast-charging mode 833 is greater than a charging current of the constant current charging stage in the slow-charging mode 834, so that a charging speed in the fast-charging mode 833 is greater than a charging speed in the slow-charging mode 834. In the fast-charging mode 833, the charging management module 801 increases the charging current for charging the energy module 2 by the charging system 810, to increase the charging speed of the charging system.
In another implementation, when the charging system 810 simultaneously charges at least two energy modules 2, the charging management module 801 controls the charging system 810 to intelligently adjust in real time a charging current for charging each energy module 2, to enable the charging system 810 to keep using a high power to charge the energy module 2, to increase the charging speed of charging the battery levels of all the energy modules 2 to target values.
In another implementation, the charging management module 801 controls the charging system 810 to first charge one of the energy modules 2, to increase the charging speed for the single energy module 2 that is first charged.
In another specific embodiment, as shown in
In this embodiment, a device charging cutoff battery level and an electric tool charging cutoff battery level are preset, in the device mode 835, the charging system 810 charges the charging cutoff battery level of the energy module 2 to the device charging cutoff battery level, and in the electric tool mode 836, the charging system 810 charges the charging cutoff battery level of the energy module 2 to the electric tool charging cutoff battery level. Specifically, the device charging cutoff battery level is 80% to 90%, and the electric tool charging cutoff battery level is 90% to 100%. That is, in the device mode 835, the charging cutoff battery level of the energy module 2 by the charging system 810 is 80% to 90%, to satisfy a requirement for powering the self-moving device 800 by the energy module 2. In the electric tool mode 836, the charging cutoff battery level of the energy module 2 by the charging system 810 is 90% to 100%, to satisfy a requirement for powering an electric tool by the energy module 2. Further, the charging mode further includes the fast-charging mode 833 and the slow-charging mode 834 in the foregoing embodiments, in the device mode 835, the charging system 810 uses the slow-charging mode 834 to charge the energy module 2, to extend the service life of the energy module 2. In the electric tool mode 836, the charging system 810 uses the fast-charging mode 833 to charge the energy module 2, to enable the energy module 2 to be rapidly fully charged when the battery level is insufficient, thereby sticking to a working progress.
Many electric tools need to be powered by at least two battery packs, in particular, at present, many electric tools are powered by a dual-pack (dual-battery pack) platform, that is, are powered by two battery packs of 20 V. Therefore, when the self-moving device 800 is used as a charging platform for charging a battery pack of an electric tool, the self-moving device 800 needs to be able to simultaneously charge at least two battery packs. To achieve the foregoing objective, the following implementation may be used.
In an implementation, as shown in
In another implementation, as shown in
In this embodiment, the charging member 600 and the self-moving device 800 can be detachably assembled. When the self-moving device 800 needs to charge at least two energy modules 2, the charging member 600 is suspended on the self-moving device 800. The charging member interface 610 is directly electrically connected to the energy module 2, to enable the self-moving device 800 to be electrically connected to at least one energy module 2 by the charging member 600, so that the self-moving device 800 simultaneously charges the energy module 2 docked to the self-moving device power interface 108 and the energy module 2 electrically connected to the charging member interface 610. In this embodiment, there is one self-moving device power interface 108. The self-moving device 800 can only charge one energy module 2 by using the self-moving device power interface 108. Therefore, the charging member 600 is detachably added, so that when the self-moving device 800 needs to charge at least two energy modules 2, the charging member 600 may be electrically connected to the self-moving device 800 for implementation. When it is not necessary to charge at least two energy modules 2, the charging member 600 may be detached from the self-moving device 800, to reduce the weight of the self-moving device 800 and provide the machine with more pleasing appearance.
In this embodiment, the self-moving device 800 may store external electrical energy in the energy module 2 in different manners in the following.
In an embodiment, as shown in
Specifically, in an embodiment, the self-moving device 800 includes an automatic-return charging mode. The charging management module 801 includes an energy information acquisition module 806 configured to acquire the related information of the energy module 2 and a control unit 808 configured to control the self-moving device 800 to automatically return for charging. In the automatic-return charging mode, the control unit 808 controls, according to the related information of the energy module 2, the self-moving device 800 to automatically return to the charging station 8 to be docked to the charging station 8 to charge the energy module 2.
In this embodiment, the automatic-return charging mode may determine a return time by using a voltage value. Specifically, the automatic-return charging modes include a room temperature return charging mode. In the room temperature return charging mode, a return voltage threshold is preset. The energy information acquisition module 806 is configured to acquire a current voltage value of the energy module 2. When the current voltage value of the self-moving device 800 is less than the return voltage threshold, the control unit controls the self-moving device to automatically return for charging. The automatic-return charging mode further includes a high-temperature return charging mode. In the high-temperature return charging mode, a high-temperature return voltage threshold is preset. The high-temperature return voltage threshold is greater than the return voltage threshold. When the current voltage value of the self-moving device 800 is less than a high temperature voltage threshold, the control unit 808 controls the self-moving device 800 to automatically return for charging. The energy information acquisition module 806 is configured to acquire a current temperature of the energy module 2. The control unit 808 controls, according to the current temperature of the energy module 2, the self-moving device 800 to select a corresponding automatic-return charging mode. Specifically, a temperature threshold is preset. When the current temperature of the energy module 2 exceeds the temperature threshold, the control unit 808 controls the self-moving device 800 to select the high-temperature return charging mode to automatically return for charging. Specifically, the energy module 2 may use a thermosensitive resistor to recognize the temperature of the energy module. The energy module 2 includes a thermosensitive resistor. The energy information acquisition module 806 detects a resistance value of the thermosensitive resistor to acquire the current temperature of the energy module. When the temperature is higher, the energy module 2 with the same voltage value has a lower battery level. Therefore, if the room temperature return charging mode is still used at a high temperature, it is highly likely that the battery level of the self-moving device 800 cannot support the return of the self-moving device 800 to the charging station 8 for charging. Therefore, at a high temperature, a corresponding high-temperature return charging mode is set to satisfy that at a high temperature, the self-moving device 800 can still successfully automatically return to the charging station 8 for charging. In this embodiment, for the return voltage threshold of the automatic-return charging mode, in addition to the foregoing temperature factors, reference may further be made to the capacity of the energy module 2. For example, when a battery pack has a higher capacity, a lower return voltage threshold may be set, so that a high-capacity battery pack has a longer working time.
In another embodiment, the automatic-return charging mode may further use a remaining battery level value of the energy module 2 to determine a return charging time. Specifically, the automatic-return charging modes include a room temperature return charging mode. In the room temperature return charging mode, a return battery level threshold is preset. The energy information acquisition module 806 is configured to acquire the remaining battery level value of the energy module 2. When the remaining battery level value of the energy module 2 is less than the return battery level threshold, the control unit 808 controls the self-moving device to return to the charging station for charging.
Specifically, in another embodiment, the self-moving device 800 further includes a non-automatic-return charging mode. In the non-automatic-return charging mode, the control unit 808 controls the self-moving device 800 to be docked to the charging station 8 to charge the energy module 2. For example, when a user urgently needs to charge the electric tool 9, and when the self-moving device 800 still does not satisfy a return charging condition, the user may actively carry the self-moving device 800 back to the charging station, or use a return button on the self-moving device 800 or a return button on a user terminal to control the self-moving device 800 to return to the charging station, to charge the energy module 2.
