Abstract
A boost charging control method, apparatus, and a storage medium, wherein the boost charging control method includes selecting, based on an electrical angle θ of the motor, two phase windings of a motor with top two inductance strengths as working windings. The method also includes controlling currents of the two phase windings, and setting a current of the other phase winding as zero, thereby causing the motor to generate a set torque. A boost charging control method, apparatus, and a storage medium are disclosed, which may cause a motor to generate a set torque, and reduce shaking and noise due to motor torque fluctuations.
