Abstract: This application provides a vehicle and a power battery heating apparatus and method thereof. In the power battery heating 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 according to heating energy to heat a coolant flowing through the power battery. A preset quadrature-axis current that causes a torque value outputted by the motor to be an appropriate value is obtained, and a corresponding preset direct-axis current is obtained according to heating power of the power battery, to control, according to the preset direct-axis current and the preset quadrature-axis current, 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 relatively small torque value is outputted at a motor shaft. The electromagnetic torque cannot cause the vehicle to move, also cannot cause a damage to parts and components of a transmission mechanism of the vehicle. It only causes the motor output shaft to output a pre-tightening force to the transmission mechanism, thereby eliminating an engagement gap and effectively avoiding jitter of the vehicle.
