Problems solved by technology
[0004] However, for areas with hot summer and cold winter, the above method cannot solve the problem of overheating and low temperature of the vehicle battery, and the method of adjusting the temperature of the vehicle battery is relatively rough and cannot be accurately controlled according to the actual state of each battery. The heating power and cooling power of each battery cannot balance the temperature of each area in the cabin when the battery temperature is adjusted.

The invention discloses a temperature adjustment method and a temperature adjustment system for a vehicle-mounted battery. The system includes a plurality of battery cooling circuits, a plurality of in-vehicle cooling circuits, and a plurality of refrigeration circuits. The method includes the following steps: obtaining a plurality of The temperature-regulated demand power and temperature-regulated actual power of multiple batteries in the battery cooling circuit; obtain the regional temperature and air-conditioning set temperature of multiple regions in the vehicle respectively; The set temperature of the air conditioner adjusts the opening degrees of multiple interior cooling circuits, multiple battery cooling circuits, and multiple refrigeration circuits. According to the actual state of each battery, the temperature of multiple areas in the compartment and the set temperature of the air conditioner, the present invention distributes the cooling capacity of the battery and each area in the compartment, and can not only adjust the temperature when the battery temperature is too high or too low. It can be adjusted to maintain the temperature of the battery within the preset range, and it can also balance the temperature of each area in the cabin.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to a method for regulating the temperature of a vehicle battery and a temperature regulating system for the vehicle battery. Background technique [0002] At present, the performance of the on-board battery of electric vehicles is greatly affected by the climate environment, and the performance of the on-board battery will be affected if the ambient temperature is too high or too low. Therefore, it is necessary to adjust the temperature of the on-board battery to maintain its temperature within a preset range . [0003] In related technologies, for areas with hot climate environment, it is necessary to add a battery cooling system to the electric vehicle to reduce the temperature of the vehicle battery when the temperature is too high; for areas with a cold climate environment, it is necessary to increase the battery heating system in the electric vehicle, to increase the tempe...
