Kind Code:
A1
Abstract:
Disclosed is a temperature regulation system for a vehicle-mounted battery, the system comprising: a vehicle-mounted air conditioning apparatus comprising a refrigeration branch and a plurality of battery cooling branches connected to the refrigeration branch in series, wherein the refrigeration branch comprises a compressor and a condenser connected to the compressor, and each battery cooling branch comprises a heat exchanger and a valve connected to the heat exchanger; a battery temperature regulation apparatus connected to the battery cooling branches to form a heat exchange flow path; and a controller connected to the vehicle-mounted air conditioning apparatus and the battery temperature regulation apparatus and used for regulating the temperature of a battery. The temperature regulation system of the present disclosure can regulate the temperature 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 the temperature.
