Abstract: This application provides a vehicle and a power battery heating apparatus and method thereof. In the method, when a current temperature value of a power battery is lower than a preset temperature value, and a heating condition of the power battery meets a preset condition, a three-phase inverter is controlled to cause a three-phase alternating current motor to generate heat to heat a coolant flowing through the power battery. A preset quadrature-axis current and a corresponding preset direct-axis current are obtained to control the three-phase inverter to adjust a phase current of the three-phase alternating current motor in the heating process, so that electromagnetic torque with a small torque value is outputted at a motor shaft. The electromagnetic torque causes the motor output shaft to output a pre-tightening force to the transmission mechanism, thereby eliminating an engagement gap and effectively avoiding jitters of the vehicle.
