Problems solved by technology
[0004] At present, whether it is an electric vehicle or a hybrid vehicle, the power generation device and the transmission device are arranged as a whole between the engine and the transmission. This arrangement is not conducive to the structural design of the automobile chassis, and also causes the chassis structure to be too complicated.

The invention discloses a double rotor engine for a pure electric car and a control method thereof. A power transmission shaft is fixedly supported on a rotor shaft and fixedly connected with an outer rotor; an inner rotor is fixedly connected with the rotor shaft; a permanent magnet fixedly supported on the rotor shaft is arranged between the inner rotor and the outer rotor; a stator three-phasewinding is fixedly connected to the inner wall of a shell of the double rotor engine; the power transmission shaft is coaxially and fixedly connected with one end of an output shaft; the other end ofthe output shaft is fixedly connected with a flywheel; the outer rotor generates induced electromotive force to rotate by means of the rotation of the inner rotor; the control unit controls power output, starting, generating, braking and accelerating functions of the engine based on various sensor signals. The engine is integrated with transmission and generating devices into one piece, which effectively increases the power transmission efficiency, and prolongs the travel distance.
Description
technical field [0001] The invention relates to a new power device and a vehicle-mounted power generation system of a pure electric car, in particular to a structure and a control method of a double-rotor engine. Background technique [0002] With the increasingly prominent energy and environmental issues, zero-pollution, high-efficiency electric vehicles have become a hot spot in the research and development of the current automotive field. Electric vehicles use a large-capacity battery pack as a power source, an electric motor as a power device, and obtain the power provided by the battery pack through a controller. During the use of electric vehicles, the mileage depends on the capacity of the battery pack, and the battery packs of existing electric vehicles are fully charged once, and the mileage that can be driven is mostly no more than 200 kilometers, and the battery life is poor; for this reason, there is an uninterrupted The most effective solution to the poor endur...
