Abstract

The invention discloses a temperature regulating system and method of a vehicle battery. The system comprises a heat exchanger, a vehicle air conditioner, a semiconductor heat exchange module, a battery heat management module, and a controller, wherein the vehicle air conditioner has an air conditioner air outlet, a first air passage is formed between the air conditioner air outlet and the heat exchanger, a second air passage is formed between a cooling end of the semiconductor heat exchange module and a first fan, a third air passage is formed between the cooling end of the semiconductor heatexchange module and a compartment, the battery heat management module is connected with the heat exchanger so as to form a heat exchange flow path, and the controller is connected with the semiconductor heat exchange module, the battery heat management module and the vehicle air conditioner. The system can regulate temperature when temperature of the vehicle battery is too high, so as to maintainthe temperature of the vehicle battery within a preset range, therefore, the vehicle battery performance is not affected by too high temperature.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a temperature regulation system for a vehicle battery, a temperature regulation system for a vehicle battery and a non-temporary readable storage medium. 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 accurately controlled according to the actual condition of the on-board battery, so that the temperature of the on-board battery cannot be maintained within a pre...
