The invention provides a hybrid power assembly for an electric vehicle, a motor controller and the electric vehicle, the hybrid power assembly comprises a generator, a motor and a dual-motor controller, and the dual-motor controller comprises a generator power circuit, a motor power circuit and a control circuit. The control circuit is used for controlling the motor power circuit or the motor power circuit to generate pulse alternating current on the direct current bus, and the pulse alternating current is used for heating the power battery. By adjusting the phase value of the pulse current output by at least one of the generator power circuit and the motor power circuit, the phase difference of the pulse current generated by the generator power circuit and the motor power circuit is reduced, so that the heating efficiency of the power battery is improved.
