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

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.

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
