The invention provides a range extender for a pure electric vehicle. The range extender for the pure electric vehicle comprises a permanent magnet generator (1) and a vehicle-mounted range extender (4), wherein the permanent magnet generator (1) is used for providing transmitted electric energy to a battery of the electric vehicle through the vehicle-mounted range extender (4); an output voltage of the vehicle-mounted range extender (4) can be kept consistent with detected busbar voltage so as to realize constant power output. The range extender for the pure electric vehicle, provided by the invention, is advantaged in that the battery can be charged during the operation of the electric vehicle and the cruising ability of the electric vehicle is effectively improved. When suffering high voltage feedback electromotive force during braking, the range extender can be adjusted to a voltage the same as the busbar voltage in time so as to ensure that the range extender is not separated from a power supply network; and moreover, the range extender can realize constant power output so as to effectively protect the generator.
