Embodiment Construction
[0026] The temperature regulation method and temperature regulation system of the vehicle battery proposed by the embodiments of the present invention and the non-transitory readable storage medium are described below with reference to the accompanying drawings.
[0027] Figure 1a-1b It is a structural schematic diagram of the temperature regulation system of the vehicle battery according to the first embodiment of the present invention. Such as Figure 1a-1b As shown, the system includes: a battery thermal management module 1, a vehicle air conditioner 2, a heat exchanger 3, a semiconductor heat exchange module 5 and a controller (not specifically shown in the figure).
[0028] Wherein, the vehicle air conditioner 2 has an air outlet of the air conditioner, and a first air duct 100 is formed between the air outlet of the air conditioner and the heat exchanger 3 . A second air duct 200 is formed between the cooling end of the semiconductor heat exchange module 5 and the first...

The invention discloses a temperature regulating system of a vehicle-mounted system. The temperature regulating system comprises a vehicle-mounted air conditioner, an in-vehicle cooling branch circuit, a battery cooling branch circuit, a semiconductor heat exchange module, a battery heat management module and a controller, wherein the vehicle-mounted air conditioner is used for providing refrigeration power for the in-vehicle cooling branch circuit and the battery cooling branch circuit; the battery cooling branch circuit is connected with the vehicle-mounted air conditioner; the semiconductorheat exchange module is used for providing refrigeration power for the in-vehicle cooling branch circuit and the battery cooling branch circuit; the battery heat management module is connected between the battery cooling branch circuit and the battery; the controller is used for obtaining the temperature regulation required power and the temperature regulation actual power of the battery and regulating the power of the semiconductor heat exchange module and / or a compressor according to the temperature regulation required power and the temperature regulation actual power of the battery. Therefore, when the temperature of the vehicle-mounted battery is too high or too low, the temperature can be regulated, the temperature of the vehicle-mounted battery remains in a preset range, and the condition that the performance of the vehicle-mounted battery is influenced due to abnormal temperature is avoided.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to a temperature regulating system for a vehicle battery. 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] However, in the related art, the method for adjusting the temperature of the on-board battery is relatively rough, and the cooling power of the on-board battery cannot be accurately controlled according to the actual condition of the on-board battery, so that the temperature of the on-board battery cannot be maintained within a preset range. Contents of the invention [0004] The present invention aims to solve one of the tec...
