With the development of science and technology, more and more electronic devices are used in people's daily lives. Different electronic devices may have different functions, but today's electronic devices all require power to operate normally.
The power source for many electronic devices is a battery, and the battery supplies power to the electronic device to ensure the normal electricity demand of the electronic device. Currently, in order to ensure the accuracy of the remaining battery level of the electronic device displayed in a coulometer when the coulometer in the electronic device is restarted after a power outage, the battery level of the electronic device needs to be calibrated. At present, the calibration of battery level is mostly carried out through the OCV curve. Since the OCV curve is inaccurate, the calibrated battery level is inaccurate.

Currently, most electronic devices are powered by batteries, such as POS machines. In case that the electronic device is turned off, the battery is still supplying power to the coulometer and peripheral circuits in the electronic device, and the battery power is consumed quickly. For convenience of explanation, a POS machine is taken as an example for the electronic device in the present application in the following description.
For the POS machine, in case that the battery level is lower than a preset value, the security CPU in the POS machine will be triggered, causing the POS machine to enter a safe mode, as a result, the user is unable to use the POS machine after getting it.
Based on the above problem, in the present application, some configurations in the POS machine will be powered off in case that the POS is turned off, such as the coulometer, the peripheral circuit, etc., to reduce battery power consumption and prolong the battery lifespan.
In addition, since the coulometer is powered off and does not work in case that the POS machine is turned off, the data in the coulometer will be lost, thus, the POS machine needs to calibrate the battery level when the POS machine is turned on to ensure that the remaining battery level of the POS machine is accurate.
Based on the above problem, in the present application, the turn-off time and turn-off remaining battery level are saved before a turn-off operation, and the battery level in the POS machine is calibrated based on the turn-off time and the turn-off remaining battery level after the POS machine is turned on, to obtain an accurate battery level.
The first battery 10 is connected to the charging management module 20 and the security CPU module 40 respectively. The charging management module 20 is connected to the peripheral circuit module 50 and the coulometer 60 respectively. The second battery 30 is connected to the security CPU module 40.
The battery capacity of the first battery 10 is greater than the battery capacity of the second battery 30. For example, batteries in the first battery are No. 5 batteries, and batteries in the second battery are button batteries.
In this embodiment, when the electronic device is turned off or turned on, at least one of the first battery 10 and the second battery 30 supplies power to the security CPU module 40. Particularly, the first battery 10 may first supply power to the security CPU module 40, and after the battery power of the first battery 10 is lower than a preset value, the second battery 30 may be initiated to supply power to the security CPU module 40.
In a possible implementation, during operation of the electronic device, the processor is configured to detect a turn-off signal, where the turn-off signal is a signal generated by acting on a turn-off button or turn-off control of the electronic device. In the present application, the turn-off signal is recorded as a first signal. For example, the first signal is generated when a hard pressing is performed on the turn-off button.
The processor, in response to a detection of the turn-off signal, reads a value of the current battery level from the coulometer 60 and writes the value of the current battery level and the current time into the peripheral circuit module 50. A first instruction is sent to the charging management module 20 after the value of the current battery level and the current time are written into the peripheral circuit module 50, where the first instruction is used to instruct the charging management module to control the first battery to stop supplying power to the coulometer 60 and the peripheral circuit module 50.
Particularly, the peripheral circuit module 50 may also include a FLASH chip, and the processor writes the value of the current battery level and the current time into the FLASH chip.
Particularly, the value of the current battery level is used to represent the turn-off remaining battery level at this turn-off, and the current time is used to represent the turn-off time at this turn-off. At the next time the electronic device is turned on, the turn-off time in the FLASH chip is the turn-off time at the last turn-off, and the turn-off remaining battery level in the FLASH chip is the remaining battery level of the electronic device at the time of the last turn-off.
As an example, if the current time is 5:20 and the electronic device needs to be turned off, then the current time and the value of the current battery level will be stored by the processor into the FLASH chip. After 20 minutes, the current time is 5:40 and the electronic device is turned on. The time and the battery level value stored in the FLASH chip are the turn-off time and the turn-off remaining battery level at the turn-off time of 5:20.
In this embodiment, after the turn-off time and turn-off remaining battery level are written by the processor into the peripheral circuit module 50, the first instruction is sent by the processor to the charging management module 20. After the first instruction is received by the charging management module 20, the paths between the charging management module 20 and the peripheral circuit module 50, as well as the charging management module 20 and the coulometer 60 are disconnected by the charging management module 20, so that the first battery 10 does not supply power to the peripheral circuit module 50 and the coulometer 60 when the electronic device is turned off, which reduces battery consumption and prolongs the lifespan of the first battery.
As an example, if a total battery capacity of the POS machine is 2000 mAh, and the power consumption per unit time of the POS machine when being turned off is 20 uAh, then the time required to consume 1% of the power is: 1%=Y*20*100%/3600/2000000, Y=3,600,000 seconds=1,000 hrs=41.66 days. That is to say, when the POS machine is in a turn-off state, it takes more than 41 days to consume 1% of the power. If 60% (according to the POS machine storage standard) of the power is saved at the time the POS machine is turned off, then it will take 41.66*60=2499.6 days=about 6.8 years to consume 60% of the power. If the POS machine is fully charged with 2000 mAh, then the POS machine can be used for 41.66*100=4166 days=11.4 years when the POS machine is in the turn-off state, which meets the standard of POS machines being trigger-able without powered failure within 3 years.
In a possible implementation, since the first battery 10 continues to supply power to the charging management module 20 when the electronic device is turned off, the charging management module 20 can still continue to operate when the electronic device is turned off.
The charging management module 20 is also configured to detect a turn-on signal, where the turn-on signal is a signal generated by acting on a turn-on button of the electronic device, or a signal generated when an external power supply is plugged into the electronic device.
The charging management module 20, in response to a detection of the turn-on signal, switches on the paths between the charging management module 20 and the peripheral circuit module 50, as well as the charging management module 20 and the coulometer 60, so that the first battery 10 is enabled to supply power to the peripheral circuit module 50 and the coulometer 60 through the charging management module 20 to ensure that each device configurations can operate normally after the electronic device is turned on.
In a possible implementation, the processor may also be configured to detect a restart signal which is a signal generated by acting on a restart button or restart control of the electronic device. For example, the restart signal is generated when the restart button is pressed by a user.
The processor, in response to a detection of the restart signal, restarts the software in the electronic device, and the various hardware in the electronic device are not powered off. Particularly, during a restart process of the electronic device, the first battery 10 continues to supply power to the peripheral circuit module 50 and the coulometer 60 through the charging management module 20. Since the coulometer 60 is not powered off during the restart process and is always in operation, the coulometer 60 is enabled to calculate the current battery level of the electronic device in real time. Thus, the battery level shown in the coulometer 60 is the current battery level of the electronic device after the electronic device is turned on, and the battery level shown in the coulometer 60 does not need to be calibrated. In case that the electronic device is restarted, the processor will not control the peripheral circuit module 50 to store the turn-off time and the turn-off remaining battery level, as a result, the electronic device cannot read the turn-off time and the turn-off remaining battery level from the peripheral circuit module 50 when the electronic device is turned on if the turn-off of electronic device is caused by restart.
In a possible implementation, the charging management module 20 may include a register. The register is initialized when the power is off, and data in the register can be restored to initial data. In the present application, the data in the register is recorded as first data, and the initial data is recorded as a second default value. For example, the second default value may be 0, 2 or 4 etc.
The register is powered on when the electronic device is turned on, and the data in the register is still the second default value until a second instruction is sent by the processor to the charging management module 20. The charging management module 20, after receiving the second instruction, updates the initial data to a first default value, and the first default value indicates that the charging management module 20 is turned on. For example, the first default value may be 1, 3, or 5, etc.
During operation of the electronic device, if the charging management module 20 has no power failure, the data in the register of the charging management module 20 will remain unchanged at the first default value until the charging management module 20 is powered off then the data in the charging management module 20 is restored to the second default value.
In a possible implementation, the turn-off of the electronic device may be caused by the first battery being loose or removed (that causes the electronic device to be powered off). In case that the electronic device is turned off due to the looseness or removal of the first battery 10, then the processor does not store the turn-off time and the remaining turn-off power in the peripheral circuit module 50, thus, when the electronic device is turned on again, the processor cannot obtain the turn-off time and the turn-off remaining battery level at the last turn-off.
If the electronic device is turned off due to the looseness or removal of the first battery 10, then the charging management module 20, the peripheral circuit module 50 and the coulometer 60 in the electronic device are all powered off when the electronic device is turned off. The data in the charging management module 20 is restored to the second default value.
In case that the electronic device is turned on, the first data in the peripheral circuit module 50 may be read by the processor first, and then based on the first data, it may be determined by the processor whether the last turn-off is caused by the looseness or removal of the first battery.
Particularly, if the first data is the first default value, then it is determined that the last turn-off is not caused by the looseness or removal of the first battery 10. Particularly, first information in the peripheral circuit module 50 is obtained when it is determined that the last turn-off is not caused by the looseness or removal of the first battery 10, and based on the first information, it is determined whether the last turn-off is performed through the turn-off button or the turn-off control. If the first information includes the turn-off remaining battery level and the turn-off time, then it is determined that the last turn-off is performed through the turn-off button or the turn-off control. In the present application, the turn-off through the turn-off button or the turn-off control is recorded as a first type. If the first information does not include the turn-off remaining battery level and the turn-off time, then it is determined that the last turn-off is performed through the restart button or the restart control, in this case, the calibration of the battery level is not required.
In this embodiment, if the second data is the second default value, then it is determined that the last turn-off is caused by the loosening or removal of the first battery. In the present application, the turn-off due to the loosening or removal of the first battery is recorded as a second type.
In a possible implementation, the processor may implement the calibration of battery level in the following method for calibrating the battery level. For the specific process of battery level calibration, reference may be made to the following method for calibrating the battery level, which will not be described again here.
The method for calibrating the battery level in an embodiment of the present application will be described in detail below with reference to
In step S101, a turn-off type when an electronic device is last turned off is obtained after the electronic device is turned on.
In this embodiment, the electronic device is turned on refers to that the electronic device starts running. The turn-off type of the electronic device may include the turn-off of the electronic device due to an action on the turn-off button or the turn-off control, the turn-off of the electronic device due to an action on the restart button or the restart control, or the turn-off of the electronic device due to the loosening or removal of the first battery.
Particularly, if the electronic device is turned off due to the action on the turn-off button or turn-off control, in this case, the first battery supplies power to the charging management module but not to the peripheral circuit module and the coulometer after the electronic device is turned off, and this kind of turn-off is recorded as the first type.
If the electronic device is turned off due to the action on the restart button or restart control, in this case, the first battery always supplies power to the charging management module, peripheral circuit module and coulometer during the process from turn-off to restart of the electronic device. The battery level in the coulometer does not need to be calibrated.
If the electronic device is turned off due to the looseness or removal of the first battery, in this case, the first battery will not power the charging management module, the peripheral circuit module and the coulometer after the electronic device is turned off.
In step S102, a current battery level of the electronic device is obtained, in case that the turn-off type is a first type, based on turn-off time and a turn-off remaining battery level when the electronic device is last turned off.
In this embodiment, the first type includes that: the first battery supplies power to the charging management module but not to the peripheral circuit module and the coulometer after the electronic device is turned off.
Particularly, the turn-off time and turn-off remaining battery level are obtained from a FLASH chip in the peripheral circuit module.
Particularly, the implementation process of step S102 may include steps S1021 to S1023.
In step S1021, a first difference of the current time minus the turn-off time.
In step S1022, a first product of the first difference and a power consumption per unit time after turn-off is calculated.
In step S1023, the current battery level is obtained based on the first product, the turn-off remaining battery level, and a preset total capacity of the battery/batteries in the first battery.
In this embodiment, the total capacity of the batteries may be set according to the type of battery used. For example, the battery capacity of No. 7 battery is different from that of No. 5 battery.
In this embodiment, a first ratio of the first product and the total capacity is calculated to obtain the turn-off power consumption.
A second difference between the turn-off remaining battery level and the first ratio is calculated to obtain the current battery level.
Particularly, a power calculation model may be utilized to calculate the current battery level. The power calculation model includes:
Where, U is the current battery level, UL is the turn-off remaining battery level, TD is the current time, TL is the turn-off time, UA is the power consumption per unit time after turn-off, and Utotal is the total capacity.
In this embodiment, after the current battery level is obtained, the current battery level may be sent to the coulometer, so that the coulometer saves the current battery level and continues to calculate subsequent battery level according to the current battery level.
In this embodiment, after the current battery level is calculated, the remaining turn-off power and turn-off time in the FLASH chip in the peripheral circuit module may be erased to prevent the battery level from being calibrated after reading the turn-off time and turn-off remaining battery level during restart, resulting in inaccurate battery level of electronic device after restarting.
In this embodiment, after the current battery level is obtained, the system in the electronic device is officially started. Each power-consuming unit in the electronic device can read the current battery level and determine whether the current battery level meets its own power needs. If the current battery level can meet its own power needs, then the power-consuming unit can operate normally. If the current battery level does not meet its own power needs, then the power-consuming unit cannot operate normally.
As an example, the power-consuming unit may include a Bluetooth unit, a printing unit, etc.
In an embodiment of the present application, the turn-off type when the electronic device is last turned off is first obtained after the electronic device is turned on; and the current battery level of the electronic device is obtained, in case that the turn-off type is the first type, based on the turn-off time and the turn-off remaining battery level when the electronic device is last turned off, where the first type includes that: the first battery supplies power to the charging management module but not to the peripheral circuit module and coulometer after the electronic device is turned off. In the present application, the turn-off time and the turn-off remaining battery level at the last turn-off are utilized to obtain the current battery level, which is more accurate than the current battery level obtained by using the OCV curve in the existing technologies.
As shown in
In step S201, a current voltage value of the first battery is obtained in case that the turn-off type is a second type.
In this embodiment, the second type includes that the first battery does not supply power to the peripheral circuit module, the charging management module and the coulometer after the electronic device is turned off.
In this embodiment, in case that the electronic device is turned off by removing the battery, the processor cannot predict in advance, thus, the peripheral circuit module cannot save the turn-off time and the turn-off remaining battery level during the turn-off. Thus, the current battery level cannot be calculated based on the turn-off time and the turn-off remaining battery level in case that the turn-off type is the second type.
After the electronic device is turned on and the coulometer is powered on, the coulometer is enabled to read the voltage value of the battery/batteries in the first battery. In the present application, the voltage value read by the coulometer is recorded as the current voltage value. The processor may obtain the current voltage value from the coulometer.
In step S202, the current battery level of the electronic device is obtained according to the current voltage value.
Particularly, a pre-stored OCV curve is obtained: a first battery level value corresponding to the current voltage value is found in the OCV curve, and the first battery level value is the current battery level of the POS machine.
In this embodiment, the OCV curve is a graph representing the relationship between voltage and battery level, and each voltage value in the curve corresponds to a battery level value.
In this embodiment, the current battery level is sent to the coulometer after the current battery level is obtained, and the coulometer performs subsequent electric quantity calculation based on the current battery level.
In the embodiment of the present application, the current voltage value and OCV curve of the battery are used to obtain the current battery level, which can ensure that the battery level can still be calibrated in case that the turn-off type is the second type and the turn-off time and turn-off remaining battery level cannot be obtained.
As shown in
In step S1011, first data in the charging management module is obtained.
In this embodiment, the first data in the charging management module is first read after the electronic device is turned on. Particularly, the first data is read from the register in the charging management module. Because during normal turn-off, the charging management module will not be powered off, i.e., is always powered on, and the power supply to the charging management module will be cut off only in case that the first battery is loose or removed, thus, a register can be arranged in the charging management module. In case that the charging management module is powered off, then the data in the register is restored to default data (initial data), that is the second default value. In case that the charging management module is turned on, then the processor may control the second default value in the register to be updated to the first default value. Based on the above configurations, the first data can be read from the register, after the electronic device is turned on, and the turn-off type at the last turn-off can be determined based on the first data.
In this embodiment, the normal turn-off is to turn off the device by pressing the turn-off button or the turn-off control, or pressing the restart button or the restart control.
In step S1012, first information in the peripheral circuit module is obtained if the first data is a first default value.
In this embodiment, the first default value indicates that the charging management module is in a power-on state before the electronic device is turned on.
In this embodiment, it may be determined that the last turn-off is a normal turn-off and the charging management module is not powered off after the last turn-off if the first data is the first default value.
In step S1013, it is determined that the turn-off type is the first type if the first information includes the turn-off remaining battery level and the turn-off time.
In step S1014, a calibration of the battery level is not required if the first information does not include the turn-off remaining battery level and the turn-off time.
In this embodiment, the battery level needs to be calibrated only when the turn-off button or the turn-off control is pressed. If the last turn-off is caused by pressing the restart button or the restart control, since the coulometer continues to be powered on in this case, the calibrate the battery level is not required.
Thus, it is also necessary to determine whether the last turn-off is a turn-off caused by pressing the turn-off button or the turn-off control after determining that the last turn-off is a normal turn-off.
In this embodiment, as the turn-off time and the turn-off remaining battery level are already stored in the peripheral circuit module during turn-off when the turn-off is performed by pressing the turn-off button or the turn-off control, thus, it can be determined whether the last turn-off is a turn-off caused due to the action on the turn-off button or turn-off control according to whether the turn-off time and the turn-off remaining battery level is presented in the peripheral circuit. If the first information includes the turn-off remaining battery level and the turn-off time, then it is determined that the turn-off type is the first type.
In step S1015, it is determined that the turn-off type is a second type if the first data is a second default value.
In this embodiment, the second default value indicates that the charging management module is in a power-off state before the electronic device is turned on.
In this embodiment, since the first data in the charging management module is updated to the second default value after the charging management module is powered off, then it is first determined whether the turn-off type is the second type based on the data in the charging management module after the electronic device is turned on. If the first data is the second default value, then it is determined that the turn-off type is the second type.
In this embodiment, a second instruction is sent by the processor to the charging management module after the turn-off type is determined. The charging management module, after receiving the second instruction, updates the second default value to the first default value and maintains the first default value unchanged until the charging management module is powered off, then, the first default value in the charging management module is changed to the second default value.
As shown in
In step S301, a value of the current battery level of the electronic device is obtained after the first signal is received.
In this embodiment, the first signal is a signal generated by acting on the turn-off button or turn-off control of the electronic device.
In this embodiment, the value of the current battery level is used to represent the turn-off remaining battery level of the electronic device at this turn-off, that is, the remaining battery level of the electronic device when the electronic device is turned off this time.
Particularly, the value of the current battery level of the electronic device is obtained from the coulometer.
In step S302, the value of the current battery level and the current time are written into the peripheral circuit module, where the current time is used as the turn-off time of this turn-off.
In step S303, a first instruction is sent to the charging management module. The first instruction is used to instruct the charging management module to control the first battery to stop supplying power to the coulometer and peripheral circuit module.
Particularly, the first instruction is sent to the charging management module after the value of the current battery level and the current time are written into the peripheral circuit module.
In an embodiment of the present application, before the electronic device is turned off, the current time and value of the current battery level are saved in the peripheral circuit module, so that the next time the device is turned on, the battery level can be calibrated based on the turn-off time and turn-off remaining battery level saved at the last turn-off.
In a possible implementation, the above method may also include steps S401 to S410.
In step S401, the first data in the register of the charging management module is obtained.
In step S402, the first information in the FLASH chip of the peripheral circuit module is obtained if the first data is the first default value.
In step S403, it is determined that the turn-off type is the first type if the first information includes the turn-off remaining battery level and the turn-off time. The current battery level of the electronic device is obtained based on the turn-off time and turn-off remaining battery level when the electronic device is last powered off. The first type includes that the first battery supplies power to the charging management module but not to the peripheral circuit module and the coulometer after the electronic device is turned off. After calculation, the first instruction is sent to the charging management module. The first instruction is used to instruct the charging management module to control the first battery to stop supplying power to the peripheral circuit module and the coulometer.
In step S404, a calibration for battery level is not required if the first information does not include the turn-off remaining battery level and the turn-off time.
In step S405, it is determined the turn-off type is the second type if the first data is the second default value. The current voltage value of the first battery read by the coulometer is obtained. The second type includes that the first battery does not supply power to the peripheral circuit module, the charging management module and the coulometer after the electronic device is turned off.
In step S406, the current battery level of the electronic device is obtained according to the current voltage value.
In step S407, the current battery level is sent to the coulometer.
In step S408, a turn-off signal is obtained and it is determined whether the turn-off signal is a signal generated by pressing the turn-off button.
In step S409, a value of the current battery level of the coulometer is read, and the current time and the value of the current battery level are saved in the FLASH chip if the turn-off signal is the signal generated by pressing the turn-off button.
In step S410, the electronic device is turned off.
