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 temperature adjustment method and temperature adjustment system of a vehicle-mounted battery. The system comprises a semiconductor heat exchange module, abattery thermal management module and a controller, wherein the semiconductor heat exchange module comprises a semiconductor heat exchanger and a heat exchanger, the semiconductor heat exchanger is provided with a heating end and a cooling end, the heating end and the cooling end are used for providing a 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 with the semiconductor heat exchanger to form a heat exchange flowing path, and the controller is used for acquiring a temperature adjustment demand power of the battery and a temperature adjustment actual power of the battery and adjusting the temperature of the battery accordingto the temperature adjustment demand power and the temperature adjustment actual power. By the system, the temperature can be adjusted when the temperature of the vehicle-mounted battery is excessively high or excessively low, the temperature of the vehicle-mounted battery is maintained within a preset range, and the influence of excessively high or excessively low temperature on the performanceof the vehicle-mounted battery is prevented.

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...
