An electric vehicle drive system includes a power battery, a drive, a motor, a detection module, a torque reference module, and a controller, and the drive includes a filtering module, a first conversion module, a first capacitor, and a second conversion module. A positive electrode of the power battery is connected to an input end of the filtering module, and a first output end of the filtering module is connected to an alternating current end of the first conversion module. One end of the first capacitor is separately connected to direct current input ends of the first conversion module and the second conversion module, and the other end of the first capacitor is separately connected to direct current output ends of the first conversion module and the second conversion module and a negative electrode of the power battery.
