The invention discloses a power control method of a range extender. According to the method, in an enabling judgment step, whether output electric energy of the range extender meets an enabling condition is judged, a target rotation speed acquisition step is performed if the answer is positive, and otherwise, the process is ended; in the target rotation speed acquisition step, the target rotation speed, corresponding to target power of output power of the range extender, of an engine of the range extender is acquired; in an engine rotation speed adjustment step, the real-time rotation speed of the engine is adjusted to reach the target rotation speed; in a reverse torque application step, real-time torque, corresponding to the real-time rotation speed, of the engine is acquired, a power generator of the range extender applies reverse torque which is approximately equal to the real-time torque in magnitude and opposite in direction to the engine; in a speed judgment step, whether the real-time rotation speed is equal to the target rotation speed is judged in real time, a power adjustment step is performed if the answer is positive, and otherwise, the engine rotation speed adjustment step and the reverse torque application step are performed again; in the power adjustment step, output torque of the engine is adjusted, so that the output power of the range extender is equal to the target power.
