A structure self-adjusting type vehicle-mounted magnetic suspension flywheel battery coping with multiple operation modes and an operating method thereof are provided. An ant-nest type channel is formed in a radiator of the flywheel battery along a circumferential direction, and a plurality of counterweight magnetic adsorption devices are symmetrically embedded in a flywheel lower sphere. When the flywheel battery operates in a charging mode, a standby mode or a discharging mode, the operation mode of the motor is flexibly changed according to different recovered energy levels or output energy levels, and the loss in the magnetic bearing system is reduced through matching of different types of magnetic bearings according to different disturbance levels. The low-loss, high-safety and stable operation of the vehicle-mounted magnetic suspension flywheel battery in various operation modes can be realized.

Structure self-adjusting type vehicle-mounted flywheel battery coping with multiple operation modes and operating method thereof

An ultra-thin vehicle-mounted magnetic suspension flywheel battery for an electric vehicle and an operating method thereof are provided. A motor bracket, an axial flux motor, a flywheel, and an inner stator, a coil, and a permanent magnet of a five-degree-of-freedom magnetic bearing are coaxially arranged in a shell from top to bottom. The flywheel consists of an upper layer, a middle layer, and a lower layer which are continuous. An upper annular groove is formed in a middle of a flywheel upper annular layer of the upper layer. The axial flux motor is placed in the upper annular groove. An annular inner groove, a middle-layer annular cavity, and a lower annular groove are communicated with each other and jointly used for placing the inner stator, the coil, and the permanent magnet of the five-degree-of-freedom magnetic bearing.
