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

A structure self-adjusting type vehicle-mounted flywheel battery coping with multiple operation modes, comprising a vacuum housing, wherein a radiator, a flywheel axial magnetic bearing stator yoke, a flywheel, and a counterweight are sequentially arranged inside the vacuum housing from top to bottom;

• an ant-nest type channel is formed in the radiator along a circumferential direction, a coolant is stored in the channel, an upper part of the channel is connected with a heat dissipation piece, and an end of the heat dissipation piece is arranged outside the vacuum housing;
• a plurality of counterweight magnetic adsorption devices are symmetrically embedded in a lower sphere of the flywheel, each of the counterweight magnetic adsorption devices comprises a magnetic isolation sleeve, a permanent magnet, a spring and a resin cover, the magnetic isolation sleeve is embedded in the lower sphere of the flywheel, the permanent magnet is arranged inside the magnetic isolation sleeve, the spring is arranged at a lower end of the permanent magnet, and the magnetic isolation sleeve is sealed by the resin cover;
• a counterweight axial passive magnetic bearing lower permanent magnet is mounted on an upper surface of a bottom cover of the vacuum housing, the counterweight axial passive magnetic bearing lower permanent magnet and a counterweight axial passive magnetic bearing upper permanent magnet are coaxial and are spaced apart from each other, and the counterweight axial passive magnetic bearing lower permanent magnet and the counterweight axial passive magnetic bearing upper permanent magnet constitute a counterweight axial passive magnetic bearing;
• a flywheel motor stator core is coaxially arranged outside the radiator, a motor is arranged on the flywheel motor stator core, and a radial magnetic resistance magnetic bearing and a radial Lorentz force magnetic bearing are arranged inside the flywheel;
• a flywheel axial Lorentz force magnetic bearing stator yoke is fixed on a central axis of the flywheel axial magnetic bearing stator yoke, a flywheel axial Lorentz force magnetic bearing control coil is wound on the flywheel axial Lorentz force magnetic bearing stator yoke, and the flywheel axial Lorentz force magnetic bearing control coil and an axial Lorentz force magnetic bearing permanent magnet constitute a flywheel axial Lorentz force magnetic bearing;
• a flywheel axial passive magnetic bearing upper permanent magnet is embedded in a lower end of the flywheel axial magnetic bearing stator yoke, and the flywheel axial passive magnetic bearing upper permanent magnet and the flywheel axial passive magnetic bearing lower permanent magnet constitute a flywheel axial passive suction magnetic bearing;
• and
• a flywheel axial Halbach axial passive magnetic bearing is mounted in a center of the bottom cover of the vacuum housing.
