The development trend of industry. From the perspective of energy saving, the energy saving effect of driving the vehicle at present is mainly reflected in two aspects: firstly, on a hybrid electric vehicle (including a part of plug-in type), an internal combustion engine can be controlled to work in a region with higher efficiency all the time; secondly, the kinetic energy can be greatly recovered in the braking process. Since the energy consumed by braking accounts for a large proportion of the energy consumed by the running of an automobile, most electrically driven vehicles are equipped with a braking energy recovery function. The flywheel energy storage has the advantages of high energy storage density, strong adaptability, wide application range, high efficiency, long service life, no pollution, low maintenance cost and the like.
However, the existing electrically-driven flywheel energy storage system generally stores and releases energy to the flywheel energy storage system through the motor and the generator, and the high-speed flywheel and the motor/generator of the electrically-driven flywheel energy storage system need to be sealed in a vacuum box body, so that the problem of temperature rise is difficult to solve.

according to the formula (1), the balance relation among the rotating speed of the permanent magnet outer rotor, the rotating speed of the magnetic adjusting ring rotor and the permanent magnet inner rotor can be known. By varying the stator field speed, the outer rotor speed can be adjusted. When the rotating speed of the magnetic adjusting ring rotor is changed, the balance relation among the rotating speed of the outer rotor, the rotating speed of the magnetic adjusting ring rotor and the permanent magnet rotor is broken, a balance rotating speed difference is formed in a short time, and at the moment, the rotating speeds of the permanent magnet inner rotor and the permanent magnet outer rotor are changed to a new balance state.
As shown in fig. 5, the stator 13 and the motor stator 25 are connected to a frequency converter and a power electronic converter, respectively; the frequency converter and the power electronic converter are connected with the storage battery; the motor magnetism-adjusting outer rotor 26 is connected with a main speed reducer through a connecting body, and the main speed reducer is connected with a driving wheel.

The driving system of the Chinese patent application 2018104533982 consists of a storage battery, a vehicle controller, a power electronic converter, a flywheel energy storage magnetic coupling transmission device, a conventional transmission system, a brake, a clutch, a differential and a driving wheel. The accumulator is used as a DC power supply, the terminal voltage of the power supply is approximately constant, and three-phase AC with variable frequency and voltage can be obtained through the action of the power electronic converter. The battery, vehicle controller, conventional transmission system, brake, clutch, differential and drive wheels constitute the primary drive system of the vehicle. The mechanical port of the flywheel energy storage magnetic coupling transmission device is connected with the brake and acts on the driving wheel through the clutch and the differential, and the electrical port of the flywheel energy storage magnetic coupling transmission device is connected with the storage battery through the power electronic converter, so that a braking energy recovery system and an automobile auxiliary driving system of the automobile are formed. When the automobile normally runs, the automobile is driven by a main driving system; when the automobile brakes and goes downhill, a braking energy recovery system is composed of a flywheel energy storage magnetic coupling transmission device, a brake, a clutch, a differential mechanism, a driving wheel, a power electronic converter and a storage battery, and the braking energy can be converted into mechanical energy of the flywheel, namely quick charging; when the automobile needs to run in an accelerated mode, an auxiliary driving system is formed by a flywheel energy storage magnetic coupling transmission device, a brake, a clutch, a differential mechanism, a driving wheel, a power electronic converter and a storage battery, mechanical energy of the flywheel is released instantaneously, and the speed of the load of the automobile can be increased by adjusting the output frequency of the power electronic converter, namely quick release; when the stored energy of the flywheel is not enough to drive the automobile to run in an accelerating way or the automobile does not need to run in an accelerating way, the mechanical energy of the flywheel can be slowly converted into electric energy to be stored in the storage battery, which is called slow release.
Compared with the Chinese patent application 2018104533982, although the utility model adds the dual-rotor motor 37, but it omits the vehicle controller, the conventional transmission system, the brake, and the like, the structure is more simplified, importantly, because the flywheel energy storage magnetic coupling transmission device 35, the magnetic coupling transmission mechanism 36 and the dual-rotor motor 37 cooperate with each other, the normal uniform speed operation of the vehicle, the recovery of braking energy when the vehicle brakes and descends, and the conversion of the flywheel kinetic energy into the vehicle kinetic energy when the vehicle accelerates and ascends, are realized, the magnetic coupling transmission device is converted into the flywheel energy storage magnetic coupling transmission device 35, the magnetic coupling transmission mechanism 36 and the dual-rotor motor 37 cooperate with each other by the Chinese patent application 2018104533982, the magnetic pole pair number of the stator magnetic field can be greatly reduced, the maximum synchronous rotating speed of the flywheel coupling transmission device is improved by times, the maximum energy storage of the flywheel is greatly improved, and simultaneously, the original advantages of the Chinese patent application 2018104533982 are kept.
