Title:
SEMICONDUCTOR BASED TEMPERATURE REGULATION METHOD AND TEMPERATURE REGULATION SYSTEM FOR VEHICLE-MOUNTED BATTERY
Document Type and Number:
WIPO Patent Application WO/2019/062944
Kind Code:
A1
Abstract:
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 comprising a semiconductor heat exchanger, wherein the semiconductor heat exchanger has a heating end and a cooling end for providing a heating power/a cooling power; a battery heat management module connected to the semiconductor heat exchanger to form a heat exchange flow path; and a controller connected to the battery heat management module and the semiconductor heat exchanger, and used for acquiring a required power and an actual power for performing temperature regulation on a vehicle-mounted battery, and for regulating the temperature of the battery according to the required power and the actual power. By means of the present application, a heating power and a cooling power of a vehicle-mounted battery can be precisely controlled according to an actual state of the vehicle-mounted battery, and the temperature is regulated when the temperature of the 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.
