A power battery heating method for an electric vehicle includes: acquiring a heating power demand of a power battery; acquiring power demand information of a driving module of the electric vehicle in real time, and determining a current heating power of the power battery according to the power demand information; acquiring a compensating heating current according to the heating power demand and the current heating power when the current heating power is less than the heating power demand; causing the motor controller to regulate a control current of the driving motor according to the compensating heating current, so that the driving motor outputs a high-frequency oscillation current equal to the compensating heating current; and causing the power battery to perform self-heating according to the high-frequency oscillation current outputted by the driving motor.
