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.

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.
