The invention provides a range extender assembly, a rear-drive series hybrid power device and a vehicle. The range extender assembly comprises an engine, a generator and a generator controller. An output shaft of the engine is connected with a speed increaser, the speed increaser comprises a first gear and a second gear which are meshed with each other, and the diameter of the first gear is larger than that of the second gear; a first shaft penetrates through the middle of the first gear, and a second shaft penetrates through the middle of the second gear. The first shaft is connected with an output shaft of the engine, and the second shaft is connected with an input shaft of the generator. The cost and the size of the range extender assembly can be reduced, meanwhile, an engine and a generator run in an efficient area, and the power running efficiency of a vehicle is improved.
