Abstract

The invention discloses a temperature regulation method and a temperature regulation system for a vehicle battery. The system comprises a vehicle air conditioner, an in-vehicle cooling branch, a battery cooling branch, a semiconductor heat exchange module, a battery thermal management module, and a controller, wherein the vehicle air conditioner is used to provide cooling power for the in-vehiclecooling branch and the battery cooling branch, the battery cooling branch is connected to the vehicle air conditioner, the semiconductor heat exchange module is used to provide cooling power for the in-vehicle cooling branch and the battery cooling branch, the battery thermal management module is connected between the battery cooling branch and the battery, and the controller is used to obtain thetemperature regulation demand power and temperature regulation actual power of the battery, and regulate the power of the semiconductor heat exchange module and the vehicle air conditioner power according to the temperature regulation demand power and temperature regulation actual power of the battery. Therefore, the temperature can be adjusted when the temperature of the vehicle battery is too high or too low to make the temperature of the vehicle battery be maintained within a preset range, thereby avoiding the situation that the performance of the vehicle battery is affected due to temperature abnormality.

Description

technical field [0001] The present invention relates to the technical field of automobiles, in particular to a method for regulating the temperature of an on-vehicle battery, a non-transitory computer-readable storage medium, and a temperature-regulating system for an on-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] However, in the related art, the method for adjusting the temperature of the on-board battery is relatively rough, and the cooling power of the on-board battery cannot be precisely controlled according to the actual condition of the on-board battery, so that the temperature of the on-board battery ...
