The present disclosure relates to a motive power system for an electric vehicle, comprising a permanent magnet synchronous motor and an electrically excited synchronous motor, one of the permanent magnet synchronous motor and electrically excited synchronous motor being a front drive electric machine for driving front wheels of the electric vehicle, and the other of the permanent magnet synchronous motor and electrically excited synchronous motor being a rear drive electric machine for driving rear wheels of the electric vehicle. A peak power and a peak torque of the permanent magnet synchronous motor are less than a peak power and a peak torque of the electrically excited synchronous motor. The powers outputted by the permanent magnet synchronous motor and the electrically excited synchronous motor are dynamically adjusted according to real-time operating conditions of the electric vehicle, such that a power loss sustained by the motive power system reaches a predetermined minimum value. The present disclosure further relates to an electric vehicle comprising the motive power system.
