[0001] Reference to Related Applications This application claims priority to Chinese Patent Application No. 2023117531416, filed on December 20, 2023, with the invention title "Charging Control Method and Related Device for Energy Storage Devices", and all its contents are incorporated herein by reference.

[0002] This application generally relates to the field of control technology, and in particular, to a charging control method and related device for energy storage devices.

Background Art

[0003] Currently, among various automotive products, campervan travel offers users a relatively good experience. Campervans can be equipped with multiple travel-related devices, such as camping equipment and fishing equipment, and each device is equipped with a portable energy storage device for power supply. Generally, such energy storage devices are charged by the campervan's control system, which arranges for the corresponding onboard charger. However, currently, charging these energy storage batteries by onboard chargers is based on an artificial method, which cannot determine the required charging amount for each energy storage device, nor can it identify which energy storage device has the most urgent charging need among multiple devices. As a result, energy storage devices with urgent charging needs may not receive sufficient charge, and consequently, the travel devices cannot be used properly, preventing users from having a good trip experience. Furthermore, under conditions where the energy storage capacity corresponding to the campervan control system is limited, the inability to clearly define the charging demand for each energy storage device leads to inefficient allocation of energy storage capacity in the campervan control system, and further to insufficient utilization of power resources in the campervan control system. [Overview of the project]

[0004] This application provides a charging control method and related apparatus for an energy storage device. Based on trip information, the amount of charge of an energy storage battery corresponding to a device used in a campervan is determined, and the on-board charger is controlled accordingly to charge the energy storage battery. This intelligently clarifies the allocation of power to the energy storage battery in the campervan, improves the efficiency of the control system's allocation of the corresponding energy storage capacity, and further improves the energy utilization rate of the energy storage capacity.

[0005] In a first embodiment, the present application provides a method for controlling the charging of an energy storage device. The method is applied to a controller in a campervan control system, which further includes an on-board charger and at least one energy storage battery. The method includes the following: Retrieve trip information. Trip information includes the current trip destination and weather information. Determine the primary device to use for the current trip destination. Based on weather information, the predicted power consumption of the first device used is determined. Based on the trip information and the predicted power consumption of the first device in use, the first charge level of the first energy storage battery corresponding to the first device in use is determined. The first energy storage battery is one of at least one energy storage batteries. The onboard charger is controlled to charge the first energy storage battery based on a first charge amount corresponding to the first energy storage battery.

[0006] Thus, in this application, the corresponding first device for use is determined based on the current trip destination in the trip information, the first charge amount of the first energy storage battery corresponding to the first device for use is determined based on the trip information, and the first energy storage battery is charged accordingly by the onboard charger. In this way, the charge demand amount corresponding to devices that may be used in the camper van is determined based on the trip information, and charging according to the charge demand amount can be automatically performed on the energy storage battery corresponding to the devices that may be used in the camper van. Therefore, it is ensured that the user's use of the first device for use is not affected by power shortages, the efficiency of the control system's allocation of corresponding energy storage capacity is improved, the energy utilization rate of the energy storage capacity is improved, and the control system can charge the energy storage battery more intelligently.

[0007] In a feasible example, the method further includes: determining at least one application scene corresponding to the destination of the current trip; determining at least one second application scene corresponding to a first use device from at least one application scene; determining scene weather information corresponding to at least one second application scene from weather information; and determining the predicted power consumption of the first use device based on the weather information, which includes determining the predicted power consumption of the first use device based on the scene weather information corresponding to at least one second application scene.

[0008] In this application, based on at least one second application scene corresponding to a first usage device in a camper van, scene weather information corresponding to at least one second application scene is determined from the weather information, and the predicted power consumption of the first usage device is determined based on the scene weather information. This increases the correlation between weather information and the current trip, and improves the accuracy of determining the predicted power consumption of the first usage device.

[0009] In a feasible example, the trip information further includes the time of arrival corresponding to the destination of the current trip. The method further includes determining the duration of use of the first device based on the time of arrival. Determining the predicted power consumption of the first device based on scene weather information corresponding to at least one second application scene includes: Determining the unit power consumption of the first device based on the scene weather information. If there is only one first device, determining the predicted power consumption of the first device based on the duration of use and the unit power consumption.

[0010] In this application, the duration of use of the first device is determined based on the arrival time, and the unit power consumption of the first device is determined based on the scene weather information. Based on the duration of use and the unit power consumption, the predicted power consumption of the first device is determined. This not only improves the efficiency of determining the predicted power consumption of the first device, but also improves the accuracy of determining the predicted power consumption of the first device.

[0011] In a feasible example, the method further includes the following: If there are multiple primary devices, determine the secondary application scene corresponding to each of the multiple primary devices. If there are multiple second application scenes corresponding to multiple first-use devices, and there are no second-use devices corresponding to multiple second application scenes for multiple first-use devices, the unit power consumption of each of the multiple first-use devices is determined based on the scene weather information. If there are multiple second application scenes corresponding to multiple first-use devices, and each of the multiple first-use devices has a second-use device corresponding to multiple second application scenes, the unit power consumption of each of the multiple first-use devices is determined based on the scene weather information. The unit power consumption of the second-use device includes the unit power consumption of multiple first-use devices, and the multiple first-use unit power consumptions correspond to multiple second application scenes. Based on the unit power consumption and usage duration of each of the multiple first-use devices, the predicted power consumption of each of the multiple first-use devices is determined.

[0012] In this application, when there are multiple first-use devices and multiple second-use devices corresponding to multiple second-application scenes, the predicted power consumption of each second-use device is determined according to each second-application scene. This prevents power shortages in the energy storage battery corresponding to the second-use device due to multiple uses of the second-use device during a trip, and improves the accuracy of determining the predicted power consumption of the second-use device.

[0013] In a feasible example, the trip information further includes the trip duration of the current trip, and determining the first charge level of the first energy storage battery corresponding to the first use device based on the predicted power consumption of the first use device includes the following: The second charge level of the first energy storage battery is determined based on the trip duration, the charging power of the onboard charger, and the first energy quantity of the first energy storage battery. The first energy quantity includes the remaining battery charge and battery capacity. If the second energy amount is determined to be equal to or greater than the predicted power consumption of the first device, the second charge amount is determined to be the first charge amount. The second energy amount is the sum of the second charge amount and the remaining battery charge of the first energy storage battery. If it is determined that the second energy energy is less than the predicted power consumption of the first device, it is determined whether or not the second energy storage battery exists in the other energy storage batteries. The other energy storage battery is at least one energy storage battery other than the first energy storage battery, and the third energy energy corresponding to the second energy storage battery is greater than or equal to the predicted power consumption of the first device. The third energy energy is the sum of the third charge amount and the remaining battery charge of the second energy storage battery, and the third charge amount is determined based on the trip duration, the charging power of the onboard charger, and the first energy energy of the second energy storage battery. If it is confirmed that a second energy storage battery exists in another energy storage battery, the second energy storage battery is confirmed as a new first energy storage battery, and the third charge amount is confirmed as the first charge amount of the new first energy storage battery. If it is determined that no second energy storage battery exists in the other energy storage battery, the combination of the third energy storage battery in the other energy storage battery and the first energy storage battery is determined as a new first energy storage battery, the second energy amount of the new first energy storage battery is set to be equal to or greater than the predicted power consumption of the first user device, and the second charge amount of the new first energy storage battery is determined as the first charge amount of the new first energy storage battery.

[0014] In this application, the first charge amount of the first energy storage battery is determined based on the rechargeable amount of the first energy storage battery and the predicted power consumption of the first user device. This makes it possible to avoid a situation where the first energy storage device cannot meet the power demand of the first user device due to charging problems.

[0015] In a feasible example, determining the second charge amount of the first energy storage battery based on the trip duration, the charging power of the onboard charger, and the first energy amount of the first energy storage battery includes the following: Determining the fourth charge amount of the first energy storage battery based on the trip duration and the charging power of the onboard charger. If the fourth charge amount is determined to be greater than the first difference, the first difference is determined as the second charge amount. The first difference is the difference between the battery capacity and the remaining charge of the first energy storage battery. If the fourth charge amount is determined to be less than or equal to the first difference, the fourth charge amount is determined as the second charge amount.

[0016] In this application, the accuracy of determining the second charge amount is improved by determining the second charge amount by comparing the fourth charge amount with the difference from the first.

[0017] A feasible example of controlling an onboard charger to charge a first energy storage battery based on a first charge amount corresponding to the first energy storage battery includes the following: If there are multiple destinations, the onboard charger is controlled to charge the fourth energy storage battery based on the first charge amount corresponding to the fourth energy storage battery. The fourth energy storage battery corresponds to the first destination. Once the fourth energy storage battery is fully charged, the onboard charger is controlled to charge the fifth energy storage battery based on the first charge amount corresponding to the fifth energy storage battery. The fifth energy storage battery corresponds to the second destination, the arrival time corresponding to the first destination is earlier than the arrival time corresponding to the second destination, and the fourth and fifth energy storage batteries constitute the first energy storage battery.

[0018] In this application, when there are multiple destinations, by arranging for priority charging of the energy storage device corresponding to the destination with the earliest arrival time, it is possible to ensure that the energy storage battery used first has priority in meeting its power supply demand, thereby improving the overall charging efficiency of the energy storage battery.

[0024] To enable those skilled in the art to better understand the technical concept of this application, the technical concept of the embodiments of this application will be described clearly and comprehensively below with reference to the drawings of the embodiments of this application. Clearly, the embodiments described are only some, and not all, embodiments of this application. All other embodiments that a person skilled in the art can obtain without creative effort based on the embodiments of this application are all within the scope of protection of this application.

[0025] In the specification, claims, and drawings of this application, terms such as “first,” “second,” etc., are used not to describe a specific sequence, but to distinguish different subjects. Furthermore, terms such as “include,” “compose,” or any other variants are intended to cover, without excluding, other components. For example, a process, method, system, product, or device comprising a series of steps is not limited to the listed steps and may optionally include other steps not listed, or may optionally include other steps specific to those processes, methods, products, or devices.

[0026] The “embodiments” as used herein means that any particular features, structures, or characteristics described in conjunction with an embodiment may be included in at least one embodiment of this application. The term “embodiments” as used elsewhere in the specification does not necessarily refer to the same embodiment, nor are they mutually exclusive, independent, or optional embodiments. Those skilled in the art will understand, either expressly or implicitly, that the embodiments described herein can be combined with other embodiments.

[0027] Referring to Figure 1, Figure 1 is a schematic diagram showing the configuration of a campervan control system according to an embodiment of this application. As shown in Figure 1, the campervan control system 100 includes a controller 101, an on-board charger 102, and a plurality of energy storage batteries 103.

[0028] The controller 101 is used to control the onboard charger 102 to charge multiple energy storage batteries 103.

[0029] The onboard charger 102 is used to charge multiple energy storage batteries 103 in the storage battery of a campervan.

[0030] The energy storage battery 103 is used to supply power to the target device, such as a lighting lamp or a trolling motor. There may be multiple energy storage batteries 103, and the application scenes and configurations corresponding to each energy storage battery 103 may differ. For example, the first energy storage battery may be used to supply power to a lighting lamp, and the second energy storage battery may be used to supply power to a trolling motor. Each energy storage battery 103 may be equipped with a Battery Management System (BMS) and may include a wired / wireless communication interface. This makes it easier for the controller 101 or the target terminal device to obtain information such as the battery power of each energy storage battery 103.

[0031] The controller 101 acquires trip information for the target. This trip information may include the current trip destination and weather information. Based on the current trip destination, the controller 101 determines the first device corresponding to the destination from among multiple target devices. Based on the weather information, the controller 101 determines the predicted power consumption of the first device, and based on the predicted power consumption of the first device and the trip information, determines the first charge level of the energy storage battery 103 corresponding to the first device. Based on the first charge level of the energy storage battery 103, the controller 101 controls the onboard charger 102 to charge the energy storage battery 103. In this way, the charging demand corresponding to devices that may be used in the camper van is determined based on the trip information, and charging according to the charging demand can be automatically performed on the energy storage battery corresponding to the devices that may be used in the camper van. Therefore, it ensures that the user's use of the primary device is not affected by power shortages, improves the efficiency of the control system's allocation of corresponding energy storage capacity, increases the energy utilization rate of the energy storage capacity, and allows the control system to charge the energy storage battery more intelligently.

[0032] Based on the above, embodiments of this application provide a method for controlling the charging of an energy storage device. Embodiments of this application will be described in detail below in conjunction with the accompanying drawings.

[0033] Referring to Figure 2, Figure 2 is a flowchart illustrating a charging control method for an energy storage device according to an embodiment of this application. This method is applied to the campervan control system described above. As shown in Figure 2, the method includes the following:

[0034] Step S201: The controller obtains trip information.

[0035] Trip information includes the current trip destination and weather information. This trip information may be acquired by the controller when the target is navigating using the campervan's corresponding navigation system, or when the target is navigating using a terminal device. Weather information may include ambient temperature, wind speed, wind direction, rainfall, etc.

[0036] Step S202: The controller determines the first-use device corresponding to the destination of the current trip.

[0037] The first device used is one of several devices placed in the camper van depending on the target object, and the first device used corresponding to the current trip destination may be determined according to the application scene corresponding to the destination. For example, if the destination is a bay, the corresponding application scene is the sea, and the corresponding first device used could include a fishing boat trolling motor or a temperature-controlled fishing box.

[0038] Step S203: The controller determines the predicted power consumption of the first device based on the weather information.

[0039] During the use of the first device, environmental factors such as weather affect its operation and, consequently, its power consumption. For example, if the target is a fishing boat at sea, encountering a headwind will necessitate increasing the boat's power, which will affect the power consumption of the trolling motor.

[0040] specifically ,fruit In a feasible embodiment, the method further includes: determining at least one application scene corresponding to the destination of the current trip; determining at least one second application scene corresponding to a first use device from the at least one application scene; and determining scene weather information corresponding to at least one second application scene from the weather information.

[0041] Determining the predicted power consumption of a first-use device based on weather information includes determining the predicted power consumption of a first-use device based on scene weather information corresponding to at least one second application scene.

[0042] The current trip destination may include multiple application scenarios, but the target trip does not necessarily relate to all of them. In this case, the application scenarios related to the target trip can be further determined based on the devices used in the camper van. For example, if the application scenarios included in the current destination are mountains and rivers, and the first device used includes a trolling motor and a temperature-controlled fishing box, then it can be determined that the first device used is for fishing or sailing, and therefore the application scenario related to the target trip can be determined to be a river.

[0043] Furthermore, the weather information corresponding to the destination should be scene weather information corresponding to at least one second application scene determined based on the first usage device, and therefore, the predicted power consumption of the first usage device can be determined based on the scene weather information. For example, if the second application scene is a river, the scene weather information may include information that affects fishing or sailing, such as wind speed and wind direction on the river surface.

[0044] For example, referring to Table 1, which is a comparison table of weather information related to this application, the following can be seen from Table 1: Scene information corresponding to different application scenes may differ. If the weather information corresponding to a water application scene and the weather information corresponding to a mountain application scene both include temperature, humidity, wind speed, wind direction, and rainfall, the scene weather information corresponding to the water application scene will include information that affects fishing and sailing, such as temperature, humidity, wind speed, and wind direction, while the scene weather information corresponding to the mountain application scene will include information that affects visibility and further affects mountain trips, such as temperature, humidity, and rainfall.

[0045] [Table 1]

[0046] In the embodiments of this application, based on at least one second application scene corresponding to a first usage device in a camper van, scene weather information corresponding to at least one second application scene is determined from the weather information, and the predicted power consumption of the first usage device is determined based on the scene weather information. This increases the correlation between weather information and the current trip, and improves the accuracy of determining the predicted power consumption of the first usage device.

[0047] Furthermore, in a feasible embodiment, the trip information further includes the time of arrival corresponding to the destination of the current trip. The method further includes determining the duration of use of the first device based on the time of arrival.

[0048] Determining the predicted power consumption of the first-use device based on scene weather information corresponding to at least one second application scene includes the following: Determining the unit power consumption of the first-use device based on the scene weather information. If there is only one first-use device, determining the predicted power consumption of the first-use device based on the duration of use and the unit power consumption.

[0049] The predicted power consumption of the first device can be determined based on the unit power consumption and duration of use of the first device. The unit power consumption of the first device may be determined based on scene weather information, and specifically, it may be determined based on both the rated operating power of the first device and the influence of the scene weather information on the use of the first device. This is because scene weather information can affect the power consumption of the first device. For example, if the first device is a boat trolling motor, if the wind direction on the river surface is opposite to the direction of the boat's movement, the trolling motor will require more power to move forward, and therefore its power consumption will increase.

[0050] The duration of use of the first device is determined based on the time the camper van arrives at its destination. This is because the time the camper van arrives at its destination may affect the duration of use of the first device by the target. For example, if the first device is a fishing device, the target may not be very concerned about the duration of use of the first device if the camper van arrives at its destination in the morning. If the camper van arrives at its destination in the afternoon, the target may be concerned that using the first device for too long will make it unsafe as it gets dark. Therefore, the duration of use of the first device corresponding to arriving at the destination at night may be shorter than the duration of use of the first device corresponding to arriving at the destination in the morning. Furthermore, the predictions relating to this application may be based on a prediction model, and the training data for the prediction model may be historical trip data corresponding to the camper van.

[0051] Specifically, both the unit power consumption of the first device and the duration of use of the first device may be determined based on empirical values ​​or predictive models. For example, the empirical value corresponding to the unit power consumption may mean the unit power consumption of the first device under the corresponding scene weather information in a historical trip. For example, the first device is a boat trolling motor that needs to provide driving force to the boat, and its rated power is 40. If there are two historical trip records, the first historical trip record includes a wind level of level 4 and a unit power consumption of 50, and the second historical trip record includes a wind level of level 2 and a unit power consumption of 45, it can be determined that the unit power consumption increases as the wind level increases. Based on the two wind levels and their corresponding unit power consumptions mentioned above, it can be simply determined that the corresponding unit power consumption increases by 2.5 for every level increase in the wind level. Therefore, if the current wind level is level 3, it can be determined that the current unit power consumption of the first device is 47.5.

[0052] As another example, the experience value corresponding to the duration of use can refer to the arrival time of the first-use device in a historical trip and the duration of use corresponding to that arrival time. For example, in the first historical trip, the arrival time of the first-use device is 10:00 AM, and the duration of use corresponding to the first-use device is 8 hours. In the second historical trip, the arrival time of the first-use device is 2:00 PM, and the duration of use corresponding to the first-use device is 4 hours. In this case, it can be determined that the later the arrival time, the shorter the duration of use corresponding to the first-use device. Simply using the two data points above, if the arrival time is 12:00 PM, it can be determined that the duration of use of the first-use device is 6 hours.

[0053] Furthermore, a prediction model based on unit power consumption may refer to a prediction model that is finalized after model training based on the unit power consumption of the first device used in a historical trip and scene weather information. For example, the training data for the prediction model corresponding to the first device used may include the unit power consumption under rated power, the actual unit power consumption, and scene weather information. Scene weather information may refer to factors that affect the power consumption of the device used under the current application scene, such as rainfall, wind speed, and temperature. Furthermore, a prediction model based on usage duration may refer to a prediction model that is finalized after model training based on the arrival time of the first device used in a historical trip and the corresponding usage duration. The above prediction model may refer to a neural network model, a linear regression model, or the like.

[0054] In the embodiments of this application, the duration of use of the first device is determined based on the arrival time, and the unit power consumption of the first device is determined based on the scene weather information. Based on the duration of use and the unit power consumption, the predicted power consumption of the first device is determined. This not only improves the efficiency of determining the predicted power consumption of the first device, but also improves the accuracy of determining the predicted power consumption of the first device.

[0055] Furthermore, in an executable embodiment, the method further includes the following: If there are multiple primary devices, determine the secondary application scene corresponding to each of the multiple primary devices. If there are multiple second application scenes corresponding to multiple first-use devices, and there are no second-use devices corresponding to multiple second application scenes for multiple first-use devices, the unit power consumption of each of the multiple first-use devices is determined based on the scene weather information. If there are multiple second application scenes corresponding to multiple first-use devices, and each of the multiple first-use devices has a second-use device corresponding to multiple second application scenes, the unit power consumption of each of the multiple first-use devices is determined based on the scene weather information. The unit power consumption of the second-use device includes the unit power consumption of multiple first-use devices, and the multiple first-use unit power consumptions correspond to multiple second application scenes. Based on the unit power consumption and usage duration of each of the multiple first-use devices, the predicted power consumption of each of the multiple first-use devices is determined.

[0056] If there are multiple primary devices, it is necessary to determine the predicted power consumption for each primary device. However, a primary device may have secondary devices corresponding to multiple application scenarios. In this case, the predicted power consumption for the secondary device includes the predicted power consumption for each of the multiple application scenarios. The calculation of the predicted power consumption for the secondary device may include the following: determining multiple unit predicted power consumption values ​​based on scene weather information corresponding to each of the multiple application scenarios corresponding to the secondary device; determining multiple scene predicted power consumption values ​​based on the multiple unit predicted power consumption values ​​and the duration of use of the secondary device; and determining the predicted power consumption for the secondary device based on the multiple scene predicted power consumption values.

[0057] Furthermore, regarding the second-use device, during an actual trip, the target may apply the second-use device to only a single application scenario. To avoid redundant calculations when calculating the predicted power consumption of the second-use device, the application scenario corresponding to the second-use device can be determined based on the application scenarios corresponding to the third-use device (excluding the second-use device) among the multiple first-use devices.

[0058] Specifically, the application scenario corresponding to the third-use device is determined, and based on the application scenario corresponding to the third-use device, the application scenario corresponding to the second-use device is determined from among multiple application scenarios corresponding to the second-use device. The application scenario corresponding to the second-use device is the same application scenario as the application scenario corresponding to the third-use device among the multiple application scenarios corresponding to the second-use device. This is because the second-use device, as a device that can be used in multiple application scenarios, does not have a particularly strong correlation with each of the usable application scenarios. In this case, if there is another use device for the first-use device that corresponds to a third application scenario which is the same as one of the multiple application scenarios corresponding to the second-use device, it can be determined that there is a high probability that the target will use the second-use device in the third application scenario during the actual trip.

[0059] For example, referring to Table 2, which is a comparison table of devices and scenes related to this application, the following can be seen from Table 2: Devices 1, 2, and 3 all correspond to mountain application scenes, but device 3 also corresponds to aquatic application scenes. When calculating the predicted power consumption of device 3, it is sufficient to calculate only the predicted power consumption of device 3 corresponding to mountain application scenes. Table 2 is as follows:

[0060] [Table 2]

[0061] In the embodiments of this application, when there are multiple first-use devices and multiple second-use devices corresponding to multiple second-application scenes, the predicted power consumption of each second-use device is determined according to each second-application scene. This prevents power shortages in the energy storage battery corresponding to the second-use device due to multiple uses of the second-use device during a trip, and improves the accuracy of determining the predicted power consumption of the second-use device.

[0062] Step S204: The controller determines the first charge amount of the first energy storage battery corresponding to the first device based on the trip information and the predicted power consumption of the first device.

[0063] The first energy storage battery is one of at least one energy storage batteries. Each of the at least one energy storage batteries corresponds to one or more user devices. Also, one user device can correspond to one or more energy storage batteries. Determining the first charge level of the first energy storage battery is to ensure sufficient power for the first user device.

[0064] The current steps are detailed below.

[0065] Specifically, in a feasible embodiment, the trip information further includes the trip duration of the current trip. Determining a first charge level of a first energy storage battery corresponding to a first use device based on the predicted power consumption of the first use device includes the following: The second charge level of the first energy storage battery is determined based on the trip duration, the charging power of the onboard charger, and the first energy quantity of the first energy storage battery. The first energy quantity includes the remaining battery charge and battery capacity. If the second energy amount is determined to be equal to or greater than the predicted power consumption of the first device, the second charge amount is determined to be the first charge amount. The second energy amount is the sum of the second charge amount and the remaining battery charge of the first energy storage battery. If it is determined that the second energy energy is less than the predicted power consumption of the first device, it is determined whether or not the second energy storage battery exists in the other energy storage batteries. The other energy storage battery is at least one energy storage battery other than the first energy storage battery, and the third energy energy corresponding to the second energy storage battery is greater than or equal to the predicted power consumption of the first device. The third energy energy is the sum of the third charge amount and the remaining battery charge of the second energy storage battery, and the third charge amount is determined based on the trip duration, the charging power of the onboard charger, and the first energy energy of the second energy storage battery. If it is confirmed that a second energy storage battery exists in another energy storage battery, the second energy storage battery is confirmed as a new first energy storage battery, and the third charge amount is confirmed as the first charge amount of the new first energy storage battery. If it is determined that no second energy storage battery exists in the other energy storage battery, the combination of the third energy storage battery in the other energy storage battery and the first energy storage battery is determined as a new first energy storage battery, the second energy amount of the new first energy storage battery is set to be equal to or greater than the predicted power consumption of the first user device, and the second charge amount of the new first energy storage battery is determined as the first charge amount of the new first energy storage battery.

[0066] The second charge is the maximum charge determined based on the current trip duration, the charging power of the onboard charger, and the first energy capacity of the first energy storage battery. If the sum of the second charge and the remaining charge of the first energy storage battery is greater than or equal to the predicted power consumption of the first user device, the second charge can be directly determined as the first charge of the first energy storage battery. If the sum of the second charge and the remaining charge of the first energy storage battery is less than the predicted power consumption of the first user device, determining the second charge as the first charge of the first energy storage battery will not satisfy the power demand of the first user device. In this case, it may be considered to determine a new first energy storage battery from at least one energy storage battery, so that the power demand of the first user device can be met after the new first energy storage battery is charged.

[0067] First, it can be determined whether the first energy storage battery can be replaced by the second energy storage battery, which is one of at least one energy storage batteries, to supply power to the first device. In this case, it is necessary to determine the third charge amount of the second energy storage battery based on the trip duration, the charging power of the onboard charger, and the first energy amount of the second energy storage battery, and it is also necessary to determine whether the sum of the third charge amount and the remaining battery charge of the second energy storage battery is equal to or greater than the predicted power consumption of the first device. If the sum of the third charge amount and the remaining battery charge of the second energy storage battery is equal to or greater than the predicted power consumption of the first device, the second energy storage battery is determined as the new first energy storage battery, and the third charge amount is determined as the first charge amount of the new first energy storage battery.

[0068] Furthermore, the first energy storage battery can be replaced by a combination of at least one third energy storage battery and the first energy storage battery to supply power to the first user device. Additionally, the sum of the second charge amount and remaining charge of the new first energy storage battery must be greater than or equal to the predicted power consumption of the first user device. If this condition is met, the second charge amount of the new first energy storage battery is set to the first charge amount of the new first energy storage battery. Also, since there are multiple first energy storage batteries in this case, the number of energy storage batteries that can be charged simultaneously must be considered when calculating the second charge amount.

[0069] In the embodiments of this application, the first charge amount of the first energy storage battery is determined based on the rechargeable amount of the first energy storage battery and the predicted power consumption of the first user device. This makes it possible to avoid a situation where the first energy storage device cannot meet the power demand of the first user device due to charging problems.

[0070] The determination of the second charge amount will be explained in detail below.

[0071] Specifically, in a feasible embodiment, determining the second charge amount of the first energy storage battery based on the trip duration, the charging power of the on-board charger, and the first energy amount of the first energy storage battery includes the following: Determining the fourth charge amount of the first energy storage battery based on the trip duration and the charging power of the on-board charger. If the fourth charge amount is determined to be greater than the first difference, the first difference is determined as the second charge amount. The first difference is the difference between the battery capacity and the remaining battery charge of the first energy storage battery. If the fourth charge amount is determined to be less than or equal to the first difference, the fourth charge amount is determined as the second charge amount.

[0072] The fourth charge amount is the maximum charge amount that the first energy storage battery can achieve, without considering the battery capacity and remaining charge of the first energy storage battery. If the fourth charge amount is greater than the difference between the battery capacity and remaining charge of the first energy storage battery, it indicates that the first energy storage battery cannot be charged to the fourth charge amount. In this case, the difference between the battery capacity and remaining charge of the first energy storage battery is determined as the second charge amount of the first energy storage battery. If the fourth charge amount is less than or equal to the difference between the battery capacity and remaining charge of the first energy storage battery, it indicates that the first energy storage battery can be charged to the fourth charge amount. In this case, the fourth charge amount is determined as the second charge amount of the first energy storage battery.

[0073] In the embodiment of this application, the accuracy of determining the second charge amount is improved by determining the second charge amount by comparing the fourth charge amount with the difference from the first.

[0074] For illustrative purposes, referring to Figure 3, which is a schematic diagram showing the configuration of an energy storage battery according to an embodiment of the present application. As shown in Figure 3, the energy storage battery includes a first battery 400 and a second battery 410. The rechargeable capacity 401 of the first battery 400 corresponds to a first difference. If the battery capacity of the first battery 400 and the battery capacity of the second battery 410 are the same, the remaining charge 402 of the first battery 400 is less than the remaining charge 411 of the second battery 410. Therefore, if the second energy amount corresponding to the first battery 400 is less than the predicted power consumption of the device using the first battery, it can be determined whether the second energy amount corresponding to the second battery 410 is less than the predicted power consumption of the device using the first battery.

[0075] Step S205: The controller controls the onboard charger to charge the first energy storage battery based on a first charge amount corresponding to the first energy storage battery.

[0076] The first energy storage battery may be one or more. When charging the first energy storage battery with an on-board charger, it is necessary to determine the number of energy storage batteries that are charged simultaneously based on the number of charging channels of the on-board charger.

[0077] Furthermore, in a feasible embodiment, controlling the on-board charger to charge the first energy storage battery based on a first charge amount corresponding to the first energy storage battery includes the following: If there are multiple destinations, controlling the on-board charger to charge the fourth energy storage battery based on a first charge amount corresponding to the fourth energy storage battery. The fourth energy storage battery corresponds to the first destination. Once the fourth energy storage battery is fully charged, controlling the on-board charger to charge the fifth energy storage battery based on a first charge amount corresponding to the fifth energy storage battery. The fifth energy storage battery corresponds to the second destination, the arrival time corresponding to the first destination is earlier than the arrival time corresponding to the second destination, and the fourth and fifth energy storage batteries constitute the first energy storage battery.

[0078] When there are multiple destinations, there are multiple first-use devices, and consequently, multiple first-use energy storage batteries corresponding to multiple first-use devices. In this case, if multiple first-use energy storage batteries cannot be charged simultaneously, it is necessary to consider the charging order of the multiple first-use energy storage batteries. Therefore, in this application, a fourth energy storage battery corresponding to the destination with the earliest arrival time is provided, taking into account the order of arrival times of each of the multiple destinations. battery Charging of the first energy storage battery is arranged first, and after the fourth energy storage battery is fully charged, charging of the fifth energy storage battery corresponding to the destination with a later arrival time is arranged. Furthermore, when considering the charging order, it is also necessary to consider the number of charging channels of the onboard charger, and the number of energy storage batteries that can be charged simultaneously is determined based on the number of charging channels.

[0079] For illustrative purposes, referring to Figure 4, which is a schematic diagram showing the configuration of a travel route according to an embodiment of the present application. As shown in Figure 4, a travel route diagram is included. The travel route diagram includes one starting point and two destinations, for example, a starting point 501, a first destination 502, and a second destination 503. From the travel route diagram, the order of arrival times from the starting point 501 to the first destination 502 and to the second destination 503 can be determined.

[0080] In embodiments of this application, when there are multiple destinations, by arranging for priority charging of the energy storage device corresponding to the destination with the earliest arrival time, it is possible to ensure that the energy storage battery used first has priority in meeting its power supply demand, thereby improving the overall charging efficiency of the energy storage battery.

[0081] For example, if the destination of the current trip is determined to be XX Beach based on trip information, the application scene corresponding to that destination can be determined to include a body of water and a sandy beach. If the beach-compatible outdoor equipment in the camper van currently only includes fishing devices (e.g., a temperature-controlled fishing box, a trolling motor), then the second application scene corresponding to the destination of the trip can be determined to include a body of water, and the first device used is a fishing device. In this case, the scene weather information related to the body of water at the current destination, determined based on the body of water, may include temperature, humidity, or wind speed. The arrival time is determined based on the current trip, the usage duration corresponding to the first device is determined based on the current arrival time, and the unit power consumption of the first device is determined based on the scene weather information and the rated power of the first device. In this case, both the corresponding usage duration and the unit power consumption of the first device can be determined based on empirical values ​​or predictive models.

[0082] Based on the usage duration and unit power consumption corresponding to the first device, the predicted power consumption of the first device is determined, and based on the trip information and the predicted power consumption of the first device, the first charge level of the first energy storage battery corresponding to the first device is determined. The campervan control system charges the first energy storage battery based on the first charge level corresponding to the first energy storage battery. In this way, it is possible to ensure that the user's use of the first device is not affected by power shortages, and to rationally allocate the energy storage battery in the campervan control system, thereby improving the efficiency of the allocation of the corresponding energy storage capacity in the control system and the energy utilization rate.

[0083] Thus, in the embodiment of this application, the corresponding first device for use is determined based on the current trip destination in the trip information, the predicted power consumption of the first device for use is determined based on the weather information in the trip information, then the first charge amount of the first energy storage battery corresponding to the first device for use is determined according to the trip information and the predicted power consumption of the first device for use, and finally, the onboard charger is controlled to charge the first energy storage battery according to the first charge amount of the first energy storage battery. In this way, the charging demand amount corresponding to devices that may be used in the camper van is determined based on the trip information, and charging according to the charging demand amount can be automatically performed on the energy storage battery corresponding to the devices that may be used in the camper van. Therefore, it is possible to ensure that the user's use of the first device for use is not affected by power shortages, improve the efficiency of the control system's allocation of corresponding energy storage capacity, improve the energy utilization rate of the energy storage capacity, and enable the control system to charge the energy storage battery more intelligently.

If there are multiple second application scenes corresponding to multiple first-use devices, and there are no second-use devices corresponding to multiple second application scenes for multiple first-use devices, then the unit power consumption of each of the multiple first-use devices is determined based on the scene weather information. When there are multiple second application scenes corresponding to multiple first-use devices, and each of the multiple first-use devices has multiple second-use devices corresponding to multiple second application scenes, the unit power consumption of each of the multiple first-use devices is determined based on the scene weather information. It is structured in this way. The unit power consumption of the second device includes multiple first unit power consumptions, and these multiple first unit power consumptions correspond to multiple second application scenarios.

The system is configured to determine the second charge amount as the first charge amount if it is determined that the second energy amount is equal to or greater than the predicted power consumption of the first device being used. The second energy amount is the sum of the second charge amount and the remaining battery charge of the first energy storage battery. If it is determined that the second energy energy is less than the predicted power consumption of the first device, the system is configured to determine whether or not the second energy storage battery exists in the other energy storage batteries, where the other energy storage battery is at least one energy storage battery other than the first energy storage battery, and the third energy energy corresponding to the second energy storage battery is greater than or equal to the predicted power consumption of the first device, and the third energy energy is the sum of the third charge amount and remaining battery charge of the second energy storage battery, where the third charge amount is determined based on the trip duration, the charging power of the onboard charger, and the first energy energy of the second energy storage battery.
