The invention discloses a temperature regulation method and a temperature regulation system of a vehicle. The temperature regulation method comprises the following steps: obtaining the temperature regulation required power of the battery; obtaining the temperature regulation actual power of the battery; Power, interior temperature and air conditioner set temperature adjust the opening of the interior cooling circuit and battery cooling circuit. The present invention adjusts the opening of the cooling circuit in the vehicle and the cooling circuit of the battery, so that the temperature of the vehicle battery can be quickly adjusted when the temperature of the vehicle battery is too high or too low, so that the temperature of the vehicle battery can be maintained within the preset range, and the occurrence of Since the temperature affects the performance of the vehicle battery, it is also possible to make the temperature inside the vehicle meet the requirements when the battery temperature meets the requirements.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle temperature regulation method and a vehicle temperature regulation system. 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 battery heating system in the electric vehicle, to increase the temperature of the on-board battery if it ...
