The invention discloses an electric motor vehicle. The electric motor vehicle comprises an accumulator set, a transmission system, a traction motor and a driving system, wherein the driving system at least comprises a frame and a wheel; a power supply end of the traction motor is connected with a power supply output end of the accumulator set; the traction motor is connected with an output shaft through a differential; the end part of the output shaft is fixedly connected with a gear by a universal coupling; the wheel comprises a tire and a hub; the inner ring surface of the hub is provided with a tooth part engaged with the gear; the center of the hub is connected with a wheel shaft through a bearing; at least one wheel of the electric motor vehicle is correspondingly connected with a generator; the generator is an outer rotor generator; a rotor of the generator is fixedly connected with the hub; a stator of the generator is fixedly connected with the wheel shaft; and a terminal of the generator is connected with a power supply input end of the accumulator set. The wheel of the electric motor vehicle rotates to drive the rotation of the generator for generating electricity; and the electricity generated by the generator is recovered and supplied to the traction motor, so that the driving range of the electric motor vehicle can be effectively prolonged.
