Embodiment Construction

[0032] 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.

[0033] 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).

[0034] 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...

Abstract

The invention discloses a temperature adjustment method and a temperature adjustment system for a vehicle-mounted battery. The system includes: a battery cooling branch, the battery cooling branch includes a heat exchanger; a semiconductor heat exchange module, and the semiconductor heat exchange module is used to provide heating power / Cooling power; battery thermal management module; car air conditioner, car air conditioner includes compressor, condenser; car interior cooling branch connected with compressor and heat exchanger; controller, controller and semiconductor heat exchange module and battery thermal management The modules are connected, and the controller is used to obtain the temperature regulation demand power and temperature regulation actual power of the battery, and control the semiconductor heat exchange module and the vehicle air conditioner to adjust the temperature of the battery according to the temperature regulation demand power and temperature regulation actual power. Thus, the temperature can be adjusted when the temperature of the on-board battery is too high or too low, so that the temperature of the on-board battery can be maintained within a preset range, and the situation that the performance of the on-board battery is affected by the high temperature can be avoided.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method for regulating the temperature of an on-vehicle battery, a non-transitory computer-readable storage medium and a temperature regulating system for an on-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 b...
