Temperature regulation system for vehicle battery

Abstract

The invention discloses a temperature regulation system for a vehicle-mounted battery, comprising: a battery cooling branch circuit, the battery cooling branch circuit includes a heat exchanger; a semiconductor heat exchange module, the semiconductor heat exchange module is used for cooling the heat exchanger; The battery thermal management module connected to the heater; the vehicle air conditioner, the vehicle air conditioner includes a compressor and the condenser; the cooling branch connected to the compressor and the heat exchanger; the controller, the controller and the semiconductor heat exchange module and the battery thermal management The modules are connected, and the controller is used to obtain the temperature regulation demand power and temperature regulation actual power of the battery, and control the semiconductor heat exchange module and the vehicle air conditioner to adjust the temperature of the battery according to the temperature regulation demand power and temperature regulation actual power. Thus, the temperature can be adjusted when the temperature of the on-board battery is too high or too low, so that the temperature of the on-board battery can be maintained within a preset range, and the situation that the performance of the on-board battery is affected by the high temperature can be avoided.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a temperature regulating system for a 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 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 preset range. Contents of the invention [0004] The present invention aims to solve one of the tec...
