The present disclosure relates to the field of control technology, and in particular, to a charging control method for an energy storage device and a related apparatus.
At present, when it comes to going on a trip, a recreational vehicle (RV) among various types of automobile products brings a better experience to users. Multiple usage devices for the trip may be arranged in the RV, such as a camping device, a fishing device, etc., and each usage device is equipped with a portable energy storage device for power supply. Generally, this kind of energy storage device is charged by a corresponding vehicle-mounted charger arranged by a RV control system, which is a manual charging method. However, with the manual charging method, a required charging amount corresponding to each energy storage device is unable to be determined, and the energy storage device with the most urgent charging demand among multiple energy storage devices is unable to be determined. Therefore, those energy storage devices with urgent charging demand may not be fully charged, resulting in that the usage devices for the trip are unable to work normally, and the users may have poor experience during the trip. Meanwhile, in a case where the energy storage capacity of the RV control system is limited, failing to determine the required charging amount of each energy storage device may lead to a low allocation efficiency of the energy storage capacity of the RV control system, thereby resulting in power resources of the RV control system not being fully utilized.

Reference is made to
The controller 101 is configured to control the vehicle-mounted charger 102 to charge the multiple energy storage batteries 103.
The vehicle-mounted charger 102 is configured to charge the multiple energy storage batteries 103 through a storage battery of the RV.
The energy storage battery 103 is configured to supply power for a usage device of a target object. For example, the usage device may be a light, a trolling motor, etc. There may be multiple energy storage batteries 103, and each energy storage battery 103 may have different configuration and may be applied in different application scenarios. For example, a first energy storage battery may supply power for the light, and a second energy storage battery may supply power for the trolling motor. Each energy storage battery 103 may be installed with a battery management system (BMS) may be installed in, and may also include a wired/wireless communication interface, which is convenient for the controller 101 or a terminal device of the target object to obtain information such as battery level of each energy storage battery 103.
The controller 101 obtains trip information of the target object, where the trip information includes a destination and weather information of a current trip. The controller 101 determines, based on the destination of the current trip, a first usage device corresponding to the destination from multiple usage devices of the target object. The controller 101 determines a predicted power consumption amount of the first usage device based on the weather information. The controller 101 determines a first charging amount of the energy storage battery 103 corresponding to the first usage device based on the trip information and the predicted power consumption amount of the first usage device. The controller 101 controls the vehicle-mounted charger 102 to charge the energy storage battery 103 based on the first charging amount corresponding to the energy storage battery 103. In this way, a required charging amount corresponding to a device that may be used in the RV may be determined through the trip information, and an energy storage battery corresponding to the device that may be used in the RV is automatically charged with the required charging amount. This not only ensures that the use of the first usage device by the user will not be affected by insufficient battery level, but also improves the allocation efficiency of the energy storage capacity of the control system, thereby improving the energy utilization rate of the energy storage capacity and making the control system more intelligent in charging the energy storage battery.
Based on this, embodiments of the disclosure provide a charging control method for an energy storage device, and the embodiments of the disclosure will be described in detail in the following in combination with the accompanying drawings.
Reference is made to
At S201, a controller obtains trip information.
The trip information includes a destination and weather information of a current trip. The trip information may be obtained by the controller when the target object is navigating on a corresponding navigation device of the RV, or may be obtained by the controller when the target object is navigating on a terminal device. The weather information may include environmental temperature, wind speed, wind direction, rainfall, etc.
At S202, the controller determines a first usage device corresponding to the destination of the current trip.
The first usage device is one of the multiple usage devices equipped in the RV by the target object. The first usage device corresponding to the destination of the current trip may be determined based on an application scenario corresponding to the destination. For example, if the destination is a bay, a corresponding application scenario is sea, and a corresponding first usage device may include a trolling motor of a fishing boat and a constant temperature fish box.
At S203, the controller determines a predicted power consumption amount of the first usage device based on the weather information.
In using the first usage device, weather and environmental factors may affect the first usage device, thereby affecting the power consumption amount of the first usage device. For example, if the target object is sailing on a fishing boat and encounters headwinds, the power of the fishing boat needs to be increased, thereby affecting the power consumption of the trolling motor.
Specifically, in a possible embodiment, the method further includes the following. At least one application scenario corresponding to the destination of the current trip is determined. At least one first application scenario corresponding to the first usage device is determined from the at least one application scenario. Scenario weather information corresponding to the at least one first application scenario is determined from the weather information.
The predicted power consumption amount of the first usage device is determined based on the weather information as follows. The predicted power consumption amount of the first usage device is determined based on the scenario weather information corresponding to the at least one first application scenario.
The destination of the current trip may include multiple application scenarios, but the trip of the target object may not involve every application scenario. In this case, application scenarios involved in the trip of the target object may be further determined based on the usage devices equipped in the RV. For example, if the application scenarios corresponding to the destination are a mountain and a river, and the first usage devices include a trolling motor and a constant temperature fish box, the application scenario involved in the trip of the target object is determined to be river because the first usage devices are used for fishing and sailing.
Meanwhile, the weather information corresponding to the destination is the scenario weather information corresponding to the at least one first application scenario determined based on the first usage device, so that the predicted power consumption amount of the first usage device may be determined through the scenario weather information. For example, if the first application scenario is a river, the scenario weather information may include weather information that affect fishing or sailing, such as wind speed and wind direction on the river surface.
Exemplarily, reference is made to table 1, which is a weather information lookup table provided in the disclosure. It may be seen that different application scenarios correspond to different scenario information. In a case where the weather information corresponding to waters application scenario and mountains application scenario are temperature, humidity, wind speed, wind direction, rainfall, etc., the scenario weather information of the waters application scenario may include weather information that affect fishing or sailing, such as temperature, humidity, wind speed, and wind direction, and the scenario weather information of the mountains application scenario may include weather information that affect the vision thereby affecting climbing, such as temperature, humidity, and rainfall. The table 1 is as follows.
In an embodiment of the disclosure, the scenario weather information corresponding to the at least one first application scenario is determined based on the at least one first application scenario corresponding to the first usage device in the RV, so that the predicted power consumption amount of the first usage device is determined. In this way, the weather information may be closely correlated with the current trip, thereby increasing the accuracy of determining the predicted power consumption amount of the first usage device.
In addition, in a possible embodiment, the trip information further includes an arrival time corresponding to the destination of the current trip, and the method further includes the following. A usage duration of the first usage device is determined based on the arrival time.
The predicted power consumption amount of the first usage device is determined based on the scenario weather information corresponding to the at least one first application scenario as follows. A unit power consumption amount of the first usage device is determined based on the scenario weather information. If there is a single first usage device, the predicted power consumption amount of the first usage device is determined based on the usage duration and the unit power consumption amount.
The predicted power consumption amount of the first usage device may be determined based on the unit power consumption amount and the usage duration of the first device. The unit power consumption amount of the first usage device may be determined based on the scenario weather information, specifically based on both the rated working power of the first usage device and the impact of the scenario weather information on the use of the first usage device. The reason is that the scenario weather information may affect the power consumption of the first usage device. For example, if the first usage device is a trolling motor of a boat, and if the wind direction on the river surface is opposite to the sailing direction of the boat, the trolling motor needs more power to move forward, thereby increasing the power consumption amount.
Since the time that the RV arrives at the destination may affect the duration of the target object using the first usage device, the usage duration of the first usage device may be determined based on the time that the RV arrives at the destination. For example, if the first usage device is a device used for fishing, and if the RV arrives at the destination in the morning, the target object may not concern the usage duration of the first usage device. If the RV arrives at the destination in the afternoon, the target object may concern that it is unsafe due to darkness if the first usage device is used for too long. In this case, the usage duration of the first usage device in a situation where the RV arrives in the evening is shorter than the usage duration of the first usage device in a situation where the RV arrives in the morning. Additionally, predictions mentioned in the disclosure are made based on a prediction model, and the training data for the prediction model may be previous trip data of the RV.
Specifically, the unit power consumption amount of the first usage device and the usage duration of the first usage device may be determined based on empirical values or the prediction model. For example, the empirical values of the unit power consumption amount may refer to the unit power consumption amount of the first usage device generated under scenario weather information corresponding to previous trips. In a case where the first usage device is a trolling motor of a boat, the trolling motor needs to provide driving power for the boat and the rated power of the trolling motor is 40. If there are two pieces of previous trip information, the first previous trip information includes a wind force level of level 4 and a unit power consumption amount of 50, and the second previous trip information includes a wind force level of level 2 and a unit power consumption amount of 45, then it may be determined that the unit power consumption amount increases as the wind force level increases. Based on the aforementioned two wind force levels and corresponding unit power consumption amounts, it may be simply determined that one level of increase in the wind force level corresponds to 2.5 of increase in the unit power consumption amount. Therefore, in a case where the current wind force level is level 3, the unit power consumption amount of the first usage device is determined to be 47.5.
For another example, the empirical values of the usage duration may refer to the arrival time of the first usage device and the usage duration corresponding to the arrival time in previous trips. For example, in a first previous trip, the arrival time of the first usage device is 10 a.m. and the usage duration of the first usage device is 8 hours. In a second previous trip, the arrival time of the first usage device is 2 p.m. and the usage duration of the first usage device is 4 hours. In this case, it may be determined that a later arrival time corresponds to a shorter usage duration of the first usage device. Simply based on the two sets of data mentioned above, the usage duration of the first usage device is determined to be 6 hours if the arrival time is 12 p.m.
In addition, a prediction model for unit power consumption amount may refer to a prediction model determined after being trained based on the unit power consumption amounts of the first usage device and the scenario weather information in previous trips. For example, the training data for the prediction model corresponding to the first usage device may include the unit power consumption amount under the rated power, the actual unit power consumption amount, and the scenario weather information. The scenario weather information may refer to factors that affect the power consumption of a usage device in a current application scenario, such as rainfall, wind speed, temperature, etc. A prediction model for usage duration may refer to a prediction model determined after being trained based on arrival times of the first usage device and corresponding usage durations in previous trips. The above prediction models may be neural network models, linear regression models, etc.
In an embodiment of the disclosure, the usage duration of the first usage device is determined based on the arrival time, and the unit power consumption amount of the first usage device is determined based on the scenario weather information, so that the predicted power consumption amount of the first usage device is determined. In this way, the efficiency of determining the predicted power consumption amount of the first usage device is improved, and the accuracy of determining the predicted power consumption amount of the first usage device is also improved.
Further, in a possible embodiment, the method further includes the following. If there are multiple first usage devices, a first application scenario corresponding to each of the multiple first usage devices is determined. If the multiple first usage devices correspond to multiple first application scenarios and the multiple first usage devices does not include any second usage device corresponding to the multiple first application scenarios, a unit power consumption amount of each of the multiple first usage devices is determined based on the scenario weather information. If the multiple first usage devices correspond to multiple first application scenarios and the multiple first usage devices include a second usage device corresponding to the multiple first application scenarios, the unit power consumption amount of each of the multiple first usage devices is determined based on the scenario weather information, where a unit power consumption amount of the second usage device includes multiple first unit power consumption amounts, and the multiple first unit power consumption amounts correspond to the multiple first application scenarios. A predicted power consumption amount of each first usage device is determined based on the unit power consumption amount and a usage duration of each first usage device.
When there are multiple first usage devices, a predicted power consumption amount corresponding to each first usage device needs to be determined. However, the multiple first usage devices may include the second usage device corresponding to multiple application scenarios. In this case, the predicted power consumption amount of the second usage device includes predicted power consumption amounts respectively corresponding to the multiple application scenarios. The predicted power consumption amount of the second usage device may be calculated as follows. Multiple unit predicted power consumption amounts are determined based on the scenario weather information respectively corresponding to the multiple application scenarios corresponding to the second usage device. Multiple scenario predicted power consumption amounts are determined based on the multiple unit predicted power consumption amounts and the usage duration of the second usage device. The predicted power consumption amount of the second usage device is determined based on the multiple scenario predicted power consumption amounts.
In addition, for the second usage device, during the actual trip, the target object may only use the second usage device in a single application scenario. In order to avoid repeated calculations when calculating the predicted power consumption amount of the second usage device, the application scenario corresponding to the second usage device may be determined based on the application scenario corresponding to a third usage device, where the third usage device is a device in the multiple first usage devices other than the second usage device.
Specifically, the application scenario corresponding to the third usage device is determined, and the application scenario corresponding to the second usage device is determined from the multiple application scenarios corresponding to the second usage device based on the application scenario corresponding to the third usage device. The application scenario corresponding to the second usage device is an application scenario in the multiple application scenarios corresponding to the second usage device, which is the same as the application scenario corresponding to the third usage device. This is because the second usage device is a device that can be used in the multiple application scenarios, which means that the second usage device has relatively weak relevance to each available application scenario. In this case, if there is a usage device in the first usage devices that corresponds to a second application scenario that is the same as any of the multiple application scenarios corresponding to the second usage device, it may be determined that the probability of the target object using the second usage device in the second application scenario during the actual trip is relatively high.
Exemplarily, reference is made to table 2, which is a device and scenario lookup table provided in the disclosure. It may be seen that device 1, device 2, and device 3 are correspond to mountains application scenario, while the device 3 also corresponds to waters application scenario. In this case, it is feasible to calculate a predicted power consumption amount of the device 3 corresponding to the mountains application scenario when calculating the predicted power consumption amount of the device 3. The table 2 is as follows.
In an embodiment of the disclosure, when there are multiple first usage devices and the multiple first usage devices include the second usage device corresponding to the multiple first application scenarios, a predicted power consumption amount of the second usage device corresponding to each first application scenario is respectively determined. In this way, insufficient battery level of the energy storage battery corresponding to the second usage device caused by using the second usage device for multiple times during the trip may be avoided, thereby improving the accuracy of determining the predicted power consumption amount of the second usage device.
At S204, the controller determines a first charging amount of the first energy storage battery corresponding to the first usage device based on the trip information and the predicted power consumption amount of the first usage device.
The first energy storage battery is an energy storage battery in the at least one energy storage battery. The at least one energy storage battery respectively corresponds to one or more usage devices. In the meantime, a single usage device may correspond to one or more energy storage batteries. The first charging amount of the first energy storage battery is determined to ensure that the first usage device has sufficient battery level.
The current operation will be described in detail in the following.
Specifically, in a possible embodiment, the trip information further includes a trip duration of the current trip. Based on the predicted power consumption amount of the first usage device, the first charging amount of the first energy storage battery corresponding to the first usage device is determined as follows. A second charging amount of the first energy storage battery is determined based on the trip duration, a charging power of the vehicle-mounted charger, and a first battery level of the first energy storage battery, where the first battery level includes a remaining battery level and a battery capacity. If a second battery level is determined to be no less than the predicted power consumption amount of the first usage device, the second charging amount is determined as the first charging amount, where the second battery level is a sum of the second charging amount and the remaining battery level of the first energy storage battery.
If the second battery level is determined to be less than the predicted power consumption amount of the first usage device, whether a second energy storage battery exists in other energy storage batteries is determined. The other energy storage batteries are energy storage batteries other than the first energy storage battery in the at least one energy storage battery. A third battery level of the second energy storage battery is no less than the predicted energy consumption amount of the first usage device. The third battery level is a sum of a third charging amount and a remaining battery level of the second energy storage battery, and the third charging amount is determined based on the trip duration, the charging power of the vehicle-mounted charger, and the first battery level of the second energy storage battery.
If there is the second energy storage battery in the other energy storage batteries, the second energy storage battery is determined as a new first energy storage battery, and the third charging amount is determined as a first charging amount of the new first energy storage battery. If there is no second energy storage battery in the other energy storage batteries, a third energy storage battery in the other energy storage batteries in combination with the first energy storage battery is determined as a new first energy storage battery, to make a second battery level of the new first energy storage battery no less than the predicted power consumption amount of the first usage device, and a second charging amount of the new first energy storage battery is determined as a first charging amount of the new first energy storage battery.
The second charging amount is the maximum charging amount determined based on the current trip duration, the charging power of the vehicle-mounted charger, and the first battery level of the first energy storage battery. In a case where the sum of the second charging amount and the remaining battery level of the first energy storage battery is no less than the predicted power consumption amount of the first usage device, the second charging amount may be directly determined as the first charging amount of the first energy storage battery. In a case where the sum of the second charging amount and the remaining battery level of the first energy storage battery is less than the predicted power consumption amount of the first usage device, even if the second charging amount is determined as the first charging amount of the first energy storage battery, the first energy storage battery is unable to meet the power demand of the first usage device. At this point, consideration may be given to determination of a new first energy storage battery from the at least one energy storage battery, so that the new first energy storage battery after charging satisfies the power demand of the first usage device.
First of all, whether the second energy storage battery in the at least one energy storage battery can replace the first energy storage battery to supply power for the first usage device may be determined. In this case, the third charging amount of the second energy storage battery needs to be determined based on the trip duration, the charging power of the vehicle-mounted charger, and the first battery level of the second energy storage battery, and whether the sum of the third charging amount and the remaining battery level of the second energy storage battery is no less than the predicted power consumption amount of the first usage device needs to be determined. In a case where the sum of the third charging amount and the remaining battery level of the second energy storage battery is no less than the predicted power consumption amount of the first usage device, the second energy storage battery is determined as the new first energy storage battery, and the third charging amount is determined as the first charging amount of the new first energy storage battery.
In addition, the case may be that the first energy storage battery is replaced by the third energy storage battery in the at least one energy storage battery in combination with the first energy storage battery, to supply power for the first usage device. Further, a condition where the sum of the second charging amount and the remaining battery level of the new first energy storage battery is no less than the predicted power consumption amount of the first usage device needs to be satisfied. Under a situation where the above condition is satisfied, the second charging amount of the new first energy storage battery is determined as the first charging amount of the new first energy storage battery. Since there are multiple first energy storage batteries under the current situation, the number of energy storage batteries that can be charged at the same time needs to be considered when calculating the second charging amount.
In an embodiment of the disclosure, the first charging amount of the first energy storage battery is determined based on a chargeable capacity of the first energy storage battery and the predicted power consumption amount of the first usage device. In this way, a situation where the first energy storage device is unable to meet the power demand of the first usage device due to charging issues may be avoided.
In addition, the determination of the second charging amount will be described in detail in the following.
Specifically, in a possible embodiment, the second charging amount of the first energy storage battery is determined based on the trip duration, the charging power of the vehicle-mounted charger, and the first battery level of the first energy storage battery as follows. A fourth charging amount of the first energy storage battery is determined based on the trip duration and the charging power of the vehicle-mounted charger. If the fourth charging amount is determined to be greater than a first difference, the first difference is determined as the second charging amount, where the first difference is a difference between the battery capacity and the remaining battery level of the first energy storage battery. If the fourth charging amount is determined to be not greater than the first difference, the fourth charging amount is determined as the second charging amount.
The fourth charging amount is the maximum charging amount of the first energy storage battery that the first energy storage battery can be charged without considering the battery capacity and the remaining battery level of the first energy storage battery. In a case where the fourth charging amount is greater than the difference between the battery capacity and the remaining battery level of the first energy storage battery, the first energy storage battery is unable to be charged with the fourth charging amount. At this point, the difference between the battery capacity and the remaining battery level of the first energy storage battery is determined as the second charging amount of the first energy storage battery. In a case where the fourth charging amount is not greater than the difference between the battery capacity and the remaining battery level of the first energy storage battery, the first energy storage battery is able to be charged with the fourth charging amount. At this point, the fourth charging amount is determined as the second charging amount of the first energy storage battery.
In an embodiment of the disclosure, the second charging amount is determined by comparing the fourth charging amount and the first difference, thereby improving the accuracy of determining the second charging amount.
Exemplarily, reference is made to
At S205, the controller controls the vehicle-mounted charger to charge the first energy storage battery based on the first charging amount corresponding to the first energy storage battery.
There may be a single first energy storage battery or multiple first energy storage batteries. When the first energy storage battery is charged by the vehicle-mounted charger, the number of energy storage batteries that can be charged at the same time needs to be determined based on the number of charging channels of the vehicle-mounted charger.
In addition, in a possible embodiment, based on the first charging amount corresponding to the first energy storage battery, the vehicle-mounted charger is controlled to charge the first energy storage battery as follows. If there are multiple destinations, the vehicle-mounted charger is controlled to charge a fourth energy storage battery based on a first charging amount corresponding to the fourth energy storage battery. When the charging of the fourth energy storage battery is completed, the vehicle-mounted charger is controlled to charge a fifth energy storage battery based on a first charging amount corresponding to the fifth energy storage battery, where the fifth energy storage battery corresponds to a second destination, an arrival time corresponding to the first destination is earlier than an arrival time corresponding to the second destination, and the fourth energy storage battery and the fifth energy storage battery constitute the first energy storage battery.
In a case where there are multiple destinations, there are multiple first usage devices, resulting in that there may be multiple first energy storage batteries corresponding to the multiple first usage devices. In this case, if the multiple first energy storage batteries are unable to be charged at the same time, consideration needs to be given to a charging sequence for the multiple first energy storage batteries. Therefore, in the disclosure, consideration is given to a sequence of arrival time corresponding to each of the multiple destinations. A fourth energy storage battery corresponding to a destination with an earlier arrival time is charged first, and then a fifth energy storage battery corresponding to a destination with a later arrival time is charged after the charging of the fourth energy storage battery is completed. Further, while considering the charging sequence, the number of charging channels of the vehicle-mounted charger also needs to be taken into account, and the number of energy storage batteries that can be charged at the same time is determined based on the number of charging channels.
Exemplarily, reference is made to
In an embodiment of the disclosure, in a case where there are multiple destinations, priority of charging will be given to an energy storage device used at a destination corresponding to an earlier arrival time, which ensures that the energy storage battery that is firstly used meets the power supply demand, thereby improving the overall charging efficiency of the energy storage batteries.
Exemplarily, if the destination of the current trip is determined based on the trip information to be a certain beach, corresponding application scenarios of the destination may be determined to include the waters and the sand. In the RV, if a device used in the trip corresponding to the beach only includes a fishing device (for example, a constant temperature fish box, a trolling motor), then a first application scenario corresponding to the destination of the trip is determined to be the waters, and the first usage device is the fishing device. At this point, based on that the destination of the trip is the waters, the scenario weather information related to the waters in the current destination is determined to include temperature, humidity, wind speed, and the like. The arrival time is determined based on the current trip, and the usage duration corresponding to the first usage device is determined based on the current arrival time. The unit power consumption amount of the first usage device is determined based on the scenario weather information and the rated power of the first usage device. The usage duration corresponding to the first usage device and the unit power consumption amount of the first usage device may be determined based on empirical values or the prediction model.
The predicted power consumption amount of the first usage device is determined based on the usage duration and the unit power consumption amount corresponding to the first usage device. The first charging amount of the first energy storage battery corresponding to the first usage device is determined based on the trip information and the predicted power consumption amount of the first usage device. The RV control system charges the first energy storage battery based on the first charging amount corresponding to the first energy storage battery. This not only ensures that the use of the first usage device by the user will not be affected by insufficient battery level, but also reasonably allocates the energy storage batteries in the RV control system, thereby improving the allocation efficiency and the energy utilization rate of the energy storage capacity of the control system.
It may be seen that, in embodiments of the disclosure, a corresponding first usage device is determined based on the destination of the current trip in the trip information, and the predicted power consumption amount of the first usage device is determined based on the weather information of the trip information. The first charging amount of the first energy storage battery corresponding to the first usage device is determined based on the trip information and the predicted power consumption amount of the first usage device. Finally, the vehicle-mounted charger is controlled to charge the first energy storage battery based on the first charging amount of the first energy storage battery. In this way, for a device that may be used in the RV, a required charging amount may be determined through the trip information, and an energy storage battery corresponding to the device that may be used in the RV is automatically charged with the required charging amount. This not only ensures that the use of the first usage device by the user will not be affected by insufficient battery level, but also improves the allocation efficiency of the energy storage capacity of the control system, thereby improving the energy utilization rate of the energy storage capacity and making the control system more intelligent in charging the energy storage battery.
