The present application discloses a boost charging control method, a boost charging circuit, an apparatus, a device and a storage medium; the method is applied to a boost charging circuit, the circuit includes a motor, a
motor controller, a
battery pack and a boost charging switch, one end of the boost charging switch is connected to a charging
pile, and the other end is respectively connected to the motor and the first phase of the
motor controller, the method includes: obtaining the effective value of the electrical
signal output by each of the other two phases of the motor in each of
multiple stages of the boost charging process; determining the execution
duty cycle value of the corresponding phase of the corresponding stage based on the electrical
signal command value of each phase of each stage and the effective value of the electrical
signal of the corresponding phase; generating a corresponding phase PWM wave of the corresponding stage based on the execution
duty cycle value of each phase of each stage, and the waveforms of the PWM
waves of the other two phases are staggered by 180 degrees; based on the PWM wave of each of the other two phases of each stage, using the
motor controller to drive the other two phases of the motor to perform boost charging control on the vehicle in the corresponding stage.
