The invention discloses a range-extending power device of an electric automobile. The range-extending power device comprises a motor and a wheel power generation device, the motor is arranged on the periphery of a wheel of the electric automobile, a driving shaft of the motor is provided with a transmission wheel used for driving the electric automobile to run, and the motor is one of a large motor and two small motors. The wheel power generation device comprises a hub and a wheel axle, the hub is arranged on the peripheral side of the wheel axle in a sleeving mode and rotationally connected with the wheel axle, a plurality of power generation coils are arranged in the hub, and stator magnets for generating power with the power generation coils are further arranged in the hub to form an electrode combination. The electric vehicle has the beneficial effects that the design is novel, the structure is reasonable, the wheels are driven to run through pressurization of the motor, more than 30% of power can be saved, meanwhile, the wheel power generation device is additionally arranged, unconsumed electric energy in the running process of the electric vehicle is converted into electric energy again, energy conservation and environmental protection are achieved, the endurance mileage is high, and large-area application and popularization can be achieved.
