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 (20) is lower than a preset temperature value, and a heating condition of the power battery (20) meets a preset condition, a three-phase inverter (11) is controlled to cause a three-phase alternating current motor (12) to generate heat according to heating energy, to heat a coolant flowing through the power battery (20), 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 (20), so as to control, according to the preset direct-axis current and the preset quadrature-axis current, the three-phase inverter (11) to adjust a phase current of the three-phase alternating current motor (12) in the heating process, where a direction of the preset direct-axis current changes periodically in the heating process, thereby making quantities of times of switching-on and switching-off of an upper leg and a lower leg of power switching devices of the same phase equal, and service life of devices balanced.
