Semiconductor-based vehicle-mounted battery temperature regulation method and system

Abstract

The invention discloses a semiconductor-based vehicle-mounted battery temperature regulation method and system. The semiconductor-based vehicle-mounted battery temperature regulation system comprisesat least one battery thermal management module correspondingly connected with at least one battery, a semiconductor heat exchange module and a controller. The semiconductor heat exchange module is connected to the at least one battery thermal management module, and includes a semiconductor heat exchanger, wherein the semiconductor heat exchanger is provided with a heating end and a cooling end forproviding heating power / cooling power. The controller is used for obtaining required temperature regulation power of the batteries and actual temperature regulation power of the batteries, and regulating the temperatures of the batteries according to the required temperature regulation power and the actual temperature regulation power. According to the semiconductor-based vehicle-mounted batterytemperature regulation method and system, the heating power and the cooling power of the vehicle-mounted batteries can be accurately controlled according to the actual status of the vehicle-mounted batteries, the temperatures are regulated when the temperatures of the vehicle-mounted batteries are too high or too low, so that the temperatures of the vehicle-mounted batteries are maintained withina preset range to avoid occurrence of the situation of affecting the performance of the vehicle-mounted batteries due to the too high or too low temperatures.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a semiconductor-based vehicle battery temperature regulation method, a semiconductor-based vehicle battery temperature regulation system, and a non-transitory computer-readable storage medium. 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] In related technologies, for areas with hot climate environment, it is necessary to add a battery cooling system to the electric vehicle to reduce the temperature of the vehicle battery when the temperature is too high; for areas with a cold climate environment, it is necessary to increase the...

Problems solved by technology

[0004] However, for regions where the summer is hot and the winter is cold, the above method cannot solve the problem of overheating and low temperature of the on-board battery, and the method of adjusting the temperature of the on-board battery is relatively rough, and it cannot be heated according to the actual condition of the on-board battery. Precise control of power and cooling power, making it impossible to ensure that the temperature of the on-board battery remains within a preset range
