摘要： A tumbler-type vehicle-mounted flywheel energy storage device with five-degree-of-freedom magnetic suspension support for an electric vehicle is provided. A flywheel is formed into a bowl by a metal flywheel rotor and a composite material ring by interference fit. The metal flywheel rotor comprises an upper-section ring, a mid-section hollow hemisphere, and a lower-section ring. The composite material ring is closely fitted outside the upper-section ring to form a bowl-shaped bowl opening part. An annular axial thrust disc protrudes inward in a radial direction from an inner wall on a bottom end of the upper-section ring. An area above the axial thrust disc is a bowl opening empty slot layer, and an area below the axial thrust disc is a sphere empty slot layer and a bowl bottom empty slot layer in sequence, which form an inner cavity of the flywheel. A supporting frame is fitted in an inner stator.

摘要： 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.

摘要： An ultra-thin vehicle-mounted magnetic suspension flywheel battery for an electric vehicle and an operating method thereof are peovided. 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.
