Document Type and Number:
WIPO Patent Application WO/2024/027065
Kind Code:
A1
Abstract:
Provided in the embodiments of the present application are a vehicle battery heating method and apparatus, and a vehicle and an electronic device. The method comprises: acquiring state information of a vehicle battery; disconnecting wheels of the vehicle from an electric motor thereof according to the state information of the vehicle battery; performing a driving operation on the disconnected electric motor, such that the rotation speed of the electric motor reaches a working rotation speed; and controlling the rotation speed of the electric motor, which reaches the working rotation speed, to fluctuate so as to result in a fluctuation in kinetic energy of a rotor, such that the vehicle battery is charged and discharged, and alternating current is then generated for heating. By means of implementing the embodiments of the present application, the capability of heating a vehicle battery is improved, a heating problem and a noise problem are prevented, and the cost is reduced.
