Temperature adjustment system of vehicle-mounted battery

Abstract

The invention discloses a temperature adjustment system of a vehicle-mounted battery. The temperature adjustment system comprises a heat exchanger, a vehicle-mounted air conditioner, a semiconductor heat exchange module, a battery thermal management module and a controller, wherein the vehicle-mounted air conditioner is provided with an air conditioner air outlet, a first air duct is formed between the air conditioner air outlet and the heat exchanger, a second air duct is formed between a cooling end of the semiconductor heat exchange module and a first fan, a third air duct is formed betweenthe cooling end of the semiconductor heat exchange module and a compartment, the battery thermal management module and the heat exchanger are connected to form a heat exchange flowing path, and the controller is connected with the semiconductor heat exchange module, the battery thermal management module and the vehicle-mounted air conditioner. The battery temperature can be adjusted by the systemwhen the temperature of the vehicle-mounted battery is excessively high, so that the temperature of the vehicle-mounted battery is maintained within a preset range, and the influence of excessively high temperature on the performance of the vehicle-mounted battery is prevented.

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 precisely controlled according to the actual condition of the on-board battery, so that the temperature of the on-board battery cannot be guaranteed to be maintained within a preset range. Contents of the invention [0004] The present invention aims to solv...
