Abstract: 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.
