Range extender and motorized equipment

The range extender comprises an engine, a power generator and a power generator controller, the engine comprises a crankshaft, the power generator is arranged adjacent to the engine, the engine comprises a motor rotor shaft, the motor rotor shaft is detachably connected to the crankshaft, and therefore the purpose of connecting the power generator and the engine is achieved; the generator controller comprises a packaging end cover and an integrally-formed driving control panel, the packaging end cover is detachably connected to the side, away from the engine, of the generator, so that the purpose of connecting the generator controller and the generator is achieved, a first containing space is formed in the packaging end cover, and the first containing space is used for containing the generator. The driving control board is located in the first containing space, so that the structure of the range extender is more compact, the occupied space needed by the range extender is reduced, a three-phase high-voltage wi
