On-board battery temperature regulation system

Abstract

Disclosed is a temperature regulation system for a vehicle-mounted battery, the system comprising a vehicle-mounted air conditioner, an in-vehicle cooling branch, a battery cooling branch, a semiconductor heat exchange module, a battery heat management module and a controller, wherein the vehicle-mounted air conditioner is used for providing a refrigeration power for the in-vehicle cooling branch and the battery cooling branch; the battery cooling branch is connected to the vehicle-mounted air conditioner; the semiconductor heat exchange module is used for providing a refrigeration power for the in-vehicle cooling branch and the battery cooling branch; the battery heat management module is connected between the battery cooling branch and a battery; and the controller is used for acquiring a required power and an actual power for performing temperature regulation on the battery, and regulating, according to the required power and the actual power, the power of the semiconductor heat exchange module and / or a compressor. Therefore, the temperature can be regulated when the temperature of a vehicle-mounted battery is excessively high or excessively low, so that the temperature of the vehicle-mounted battery is kept within a pre-set range, thus preventing the performance of the vehicle-mounted battery from being affected by a temperature abnormality.

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...
