Abstract

The invention discloses a temperature adjusting method and a temperature adjusting system of a vehicle-mounted battery; the temperature adjusting system of the vehicle-mounted battery comprises a compressor, a condenser in connection with the compressor, an in-vehicle cooling branch circuit and a battery cooling branch circuit, a semiconductor heat exchange module, a battery heat management module, and a controller, wherein the in-vehicle cooling branch circuit and the battery cooling branch circuit are connected with the compressor, the semiconductor heat exchange module is used for providingcooling power for a heat exchanger, the battery heat management module is connected with the heat exchanger to form a heat exchange flow path; the controller is used for acquiring temperature adjusting demand power and temperature adjusting actual power of the battery, and adjusting the cooling power of the semiconductor heat exchange module and / or the compressor according to the temperature adjusting demand power and the temperature adjusting actual power. The system can be used for adjusting the battery temperature according to the actual condition of the vehicle-mounted battery when the temperature of the vehicle-mounted battery is too high, so that the temperature of the vehicle-mounted battery is maintained in a preset range, and the situation that the performance of the vehicle-mounted battery is influenced due to too high temperature is avoided.

Description

technical field [0001] The 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] In related technologies, the method for adjusting the temperature of the on-board battery is relatively rough, and the heating power and cooling power cannot be precisely controlled according to the actual condition of the on-board battery, so that the temperature of the on-board battery cannot be guarantee...
