Document Type and Number:
WIPO Patent Application WO/2022/242323
Kind Code:
A1
Abstract:
Provided are a heat control method and apparatus, and a vehicle, applied to a controller of a vehicle. The vehicle comprises a heat pump system, a motor, and a battery. The method comprises: when the heat pump system is started, obtaining a first temperature difference inside the battery, a first temperature of a battery body, a second temperature of a first cooling circuit of the motor, and a second temperature difference between a target temperature and an actual temperature of a passenger cabin of the vehicle (S100); and controlling the heat pump system to recover the waste heat of the first cooling circuit according to the first temperature difference, the second temperature difference, the first temperature, and the second temperature, or controlling the first cooling circuit to adjust the temperature of the battery (S200). Three functions of recovering heat from the air by a heat pump, recovering the waste heat of the motor by the heat pump system, and heating the battery by the waste heat of the motor are combined, so that the heat pump system has a higher energy efficiency, and the pure electric endurance mileage of the whole vehicle at a low temperature is improved.
