Abstract
A motor drive apparatus includes a three-phase inverter and a three-phase motor. A first terminal of the three-phase inverter is connected to a positive electrode of a power battery. A second terminal of the three-phase inverter is connected to a negative electrode of the power battery Three phase coils of the three-phase motor are respectively connected to midpoints of three phase legs of the three-phase inverter. The motor drive apparatus is configured to simultaneously control (i) a process of charging the power battery by a power supply module, (ii) a torque of the three-phase motor at a zero output, and (iii) the three-phase inverter and the three-phase motor to heat a heat exchange medium flowing through at least one of the three-phase inverter or the three-phase motor.
