The invention relates to a power system for an electric vehicle, which comprises a permanent magnet synchronous motor and an electro-magnetic synchronous motor, one of the permanent magnet synchronous motor and the electro-magnetic synchronous motor is a front-drive motor for driving front wheels of the electric vehicle, and the other of the permanent magnet synchronous motor and the electro-magnetic synchronous motor is a rear-drive motor for driving rear wheels of the electric vehicle. And the other one of the permanent magnet synchronous motor and the electro-magnetic synchronous motor is a rear drive motor for driving rear wheels of the electric vehicle. The peak power and the peak torque of the permanent magnet synchronous motor are smaller than the peak power and the peak torque of the electro-magnetic synchronous motor. And the power output by the permanent magnet synchronous motor and the electrically excited synchronous motor is dynamically adjusted according to the real-time working condition of the electric vehicle, so that the power loss borne by the power system reaches a preset minimum value. The invention further relates to an electric vehicle comprising the power system.
