An electric drive system includes a pair of inverters, an open winding motor, a first switch connected between upper bridges of the inverters, and a control apparatus. In a boost charging mode, the control apparatus controls the first switch to turn off, an upper bridge arm of the second inverter to turn on, and a lower bridge arm of the second inverter to turn off, and a lower bridge arm and an upper bridge arm of a corresponding phase of the first inverter to be alternately turned on in a boost charging mode, such that a charging current first flows towards a winding of a corresponding phase of the open winding motor and then flows towards a battery through the winding of the corresponding phase of the open winding motor. As such, the electric drive system can implement boost charging.
