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

Abstract

The invention discloses a semiconductor-based vehicle battery temperature adjustment method and a temperature adjustment system. The system includes: a semiconductor heat exchange module, including a semiconductor heat exchanger and a heat exchanger, and the semiconductor heat exchanger has a heating end and a cooling end. To provide heating power / cooling power, the heat exchanger is arranged opposite to at least one of the heating end and the cooling end of the semiconductor heat exchanger; the battery thermal management module is connected to the heat exchanger to form a heat exchange flow path; the controller is used to obtain The temperature of the battery regulates the required power and the temperature of the battery regulates the actual power, and the temperature of the battery is adjusted according to the temperature-regulated demanded power and the temperature-regulated actual power. The invention can adjust the temperature of the vehicle battery when the temperature is too high or too low, so as to maintain the temperature of the vehicle battery in a preset range, and avoid the situation that the performance of the vehicle battery is affected by the temperature being too high or too low.

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...
