This application relates to the field of electric vehicles, and in particular, to a vehicle thermal management system, a drive apparatus, and an electric vehicle. The thermal management system includes: a motor configured to drive a compressor of an air conditioner to work, N resistor branches, and a driver configured to drive the motor and resistors on the N resistor branches to work. The driver includes a control circuit and an inverter circuit. The control circuit is configured to control the inverter circuit to output an alternating current to the motor, to drive the motor to rotate. The control circuit is further configured to control the inverter circuit to output currents to the N resistor branches, so that the resistors on the N resistor branches generate heat. Therefore, the motor and a heat emitting resistor are driven by using the single driver. This reduces costs of the thermal management system and saves space of the thermal management system.
