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

Abstract

The invention discloses a semiconductor-based vehicle battery temperature adjustment method and temperature adjustment system. The system includes: at least one battery thermal management module respectively connected with at least one battery; semiconductor heat exchange connected with the at least one battery thermal management module The module includes a semiconductor heat exchanger. The semiconductor heat exchanger has a heating end and a cooling end to provide heating power / cooling power; the controller is used to obtain the battery temperature regulation demand power and the battery temperature regulation actual power, and according to the temperature Adjust the demand power and temperature adjust the actual power to adjust the temperature of the battery. The present invention can precisely control the heating power and cooling power of the on-board battery according to the actual state of the on-board battery, and adjust the temperature when the temperature of the on-board battery is too high or too low, so as to maintain the temperature of the on-board battery within a preset range, and avoid occurrence of Conditions that affect the performance of the vehicle battery due to excessively high or 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
