[0053] This embodiment provides a control method for a vehicle-mounted power battery management system of an electronic device running on the above vehicle. Figure 2 is a flow chart of a control method of a vehicle power battery management system according to one embodiment of the present invention. Figure 2As shown, the process includes the following steps: Step S1: Collecting the real-time working condition information of the vehicle's on-board power battery and the on-board power battery management system sensed by the sensor, wherein the working condition information includes at least one of the following: the temperature of the on-board power battery, the actual working voltage of the solar charging device.

Step S3: When the comparison result meets the preset conditions, a control instruction set is generated, and the control instruction set is used to control the vehicle power battery management system to execute the target operating mode, wherein the target operating mode includes at least one of the following: solar assisted cooling operating mode, solar combined heating operating mode, solar assisted heating operating mode, and solar assisted charging operating mode.

[0054] In the embodiment of the present application, by comparing the real-time working condition information of the vehicle-mounted power battery and the vehicle-mounted power battery management system with the preset information of the vehicle-mounted power battery management system, the vehicle-mounted power battery management system is controlled to execute the target working mode according to the comparison result, so that the solar energy provides power to the temperature control system of the vehicle-mounted power battery, so that the vehicle-mounted power battery works within a suitable temperature range, avoiding low charging and discharging efficiency of the vehicle-mounted power battery due to too low working temperature, and even irreversible damage to the battery body. In addition, by using solar energy to provide power to the temperature control system of the vehicle-mounted power battery, the frequency of using the vehicle-mounted power battery's own power to heat the battery is reduced, the power consumption of the vehicle-mounted power battery is reduced, the cycle life of the vehicle-mounted power battery is extended, and the vehicle mileage is avoided.

[0055] Optionally, the real-time operating condition information of the vehicle-mounted power battery and the vehicle-mounted power battery management system is compared with the preset information of the vehicle-mounted power battery management system of the vehicle to obtain a comparison result. When the comparison result meets the preset conditions, a control instruction set is generated, including: comparing the temperature of the vehicle-mounted power battery with the second temperature initialized when the cooling control is turned on. When the temperature of the vehicle-mounted power battery is less than or equal to the second temperature initialized when the cooling control is turned on, it is determined whether the temperature of the vehicle-mounted power battery is greater than the first temperature initialized when the cooling control is turned on. If so, it is determined whether the actual working voltage of the solar charging device is greater than the lower limit of the effective working voltage of the solar charging device. If so, a first target instruction in the control instruction set is generated, and the first target instruction is used to control the vehicle-mounted power battery management system to execute the solar-assisted cooling working mode. In the above steps, by sequentially judging the temperature of the vehicle-mounted power battery and the actual working voltage of the solar charging device, the control process is made more accurate, avoiding the situation where the solar charging device cannot provide sufficient power to each actuator due to its own voltage being too low.

[0056] Optionally, controlling the vehicle power battery management system to execute the solar assisted cooling working mode includes: controlling the switch circuit to open so that the solar charging device provides power to each actuator of the vehicle, and controlling the power battery cooling pipe radiator to perform heat exchange operation to reduce the temperature of the coolant in the vehicle power battery temperature control system.

[0059] Optionally, controlling the vehicle power battery management system to execute the solar auxiliary charging working mode includes: controlling the switch circuit to open so that the solar charging device provides charging power to the vehicle's on-board auxiliary power supply. In the above steps, the solar charging device charges the on-board auxiliary power supply, and the on-board auxiliary power supply can directly provide power to various actuators of the vehicle, the battery auxiliary heating device, and the main heating device of the battery, that is, the solar charging device indirectly reduces the power consumption of the vehicle power battery.

[0060] Optionally, the real-time operating condition information of the vehicle-mounted power battery and the vehicle-mounted power battery management system is compared with the preset information of the vehicle-mounted power battery management system of the vehicle to obtain a comparison result. When the comparison result meets the preset conditions, a control instruction set is generated, including: comparing the temperature of the vehicle-mounted power battery with the second temperature initialized when the cooling control is turned on. When the temperature of the vehicle-mounted power battery is less than or equal to the second temperature initialized when the cooling control is turned on, it is judged whether the temperature of the vehicle-mounted power battery is greater than the first temperature initialized when the cooling control is turned on. If not, it is judged whether the temperature of the vehicle-mounted power battery is less than or equal to the second temperature initialized when the heating control is turned on. If not, it is judged whether the temperature of the vehicle-mounted power battery is less than or equal to the first temperature initialized when the heating control is turned on. If not, it is judged whether the real-time value of the state of charge of the vehicle-mounted auxiliary power supply is less than or equal to the lower limit threshold of the charging state of charge of the vehicle-mounted auxiliary power supply. If yes, it is judged whether the actual working voltage of the solar charging device is greater than the lower limit value of the effective working voltage of the solar charging device. If yes, a second target instruction in the control instruction set is generated, and the second target instruction is used to control the vehicle-mounted power battery management system to execute the solar auxiliary charging working mode. In the above steps, the control process is made more accurate by making multiple judgments on the vehicle power battery temperature, the real-time value of the charge state of the vehicle auxiliary power supply, and the actual working voltage of the solar charging device.

If yes, a third target instruction in the control instruction set is generated, and the third target instruction is used to control the on-board power battery management system to execute the solar joint heating working mode. In the above steps, the control process is made more accurate by making multiple judgments on the on-board power battery temperature and the actual working voltage of the solar charging device.
