SEMICONDUCTOR-BASED TEMPERATURE REGULATION METHOD AND TEMPERATURE REGULATION SYSTEM FOR VEHICLE-MOUNTED BATTERY

WIPO Patent Application WO/2019/062955

A1

Disclosed are a semiconductor-based temperature regulation method and temperature regulation system for a vehicle-mounted battery. The system comprises: a semiconductor heat exchange module (6) comprising a semiconductor heat exchanger (2) and a heat exchanger (1), wherein the semiconductor heat exchanger (2) has a heating end and a cooling end for providing a heating power/a cooling power, and the heat exchanger (1) is arranged opposite at least one of the heating end and the cooling end of the semiconductor heat exchanger (2); a battery heat management module (3) connected to the heat exchanger (1) to form a heat exchange flow path; and a controller (8) used for acquiring a required power and an actual power for performing temperature regulation on a vehicle-mounted battery, and regulating the temperature of a battery according to the required power and the actual power. The system 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 excessively high or excessively low temperature.
