The invention discloses a gradual perpetual motion power electric vehicle. The gradual perpetual motion power principle of gradual grade mutual power and circular energy complementation perpetual motion is adopted to realize perpetual motion operation. The vehicle is the gradual perpetual motion power electric vehicle which does not require external electric energy, is emission-free, can generate lasting mechanical energy and electric power, is never powered-off and is most perfect. Meanwhile, the gradual perpetual motion power electric vehicle can also transmit a large amount of electric power to other domestic electric appliances. The gradual perpetual motion power electric vehicle consists of a gradual perpetual motion machine cabin, a gradual perpetual motion system, a reduction control power machine, an engine, a power generator, an extended-capacity storage battery and a fan, wherein the gradual perpetual motion machine cabin comprises a perpetual motion power device inner sleeve, a perpetual motion machine body outer shell front plate, a flange disc, a perpetual motion machine body outer shell rear cover, a gradual perpetual motion connecting shaft rod, a high-temperature resistant axial rare-earth strong magnet, gradual magnetic power and multi-stage power source device discs, a radial permanent-magnetic high-frequency magnet, an air exchange ventilating cover, an integral machine base fixing bracket and the like. The vehicle is provided with a new energy source which is inexhaustible.
