The present disclosure discloses a power battery heating method and device for an electric vehicle and a vehicle. The method 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, during control of the driving motor to drive the electric vehicle into operation according to the power demand information by the motor controller, 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. According to the present disclosure, the high-frequency oscillation current outputted by the driving motor is increased to satisfy a self-heating demand of the power battery while it is ensured that the power demand information is satisfied, thereby improving the heating rate and efficiency.
