Abstract

The invention discloses a magnetic suspension flywheel energy storage battery. The battery includes a battery shell, a storage shell, an accelerating flywheel, an external rotating shaft, a magnetic suspension flywheel and a magnetic suspension power generation device. A longitudinal magnetic suspension bearing and a transverse limiting magnetic bearing are used to avoid the vibration and gyroscopic effect of a flywheel energy storage battery system. The accelerating flywheel structure is added to allow the magnetic suspension flywheel to achieve maximum acceleration, and so the magnetic suspension flywheel can always be accelerated by external force so as to avoid external deceleration benefits. A method of combining electromagnetic transmission and contact transmission is adopted. Firstly, the rotation speed of the power generation device is slowly increased by electromagnetic flexible transmission, then the contact transmission is used to make the power generation device well transition from a stationary state to a high-speed rotation state without losing transmission efficiency, and the damage of the rotating shaft caused by forced speed increase and rigid collision of the power generation device can be avoided. The power generation device also adopts the magnetic suspension design so as to avoid friction loss, improve transmission efficiency and improve kinetic energy utilization rate.

Description

technical field [0001] The invention belongs to the field of flywheel application technology, and in particular relates to a magnetic levitation flywheel energy storage battery. Background technique [0002] Among various energy storage technologies, the development speed of chemical energy storage has always been ahead of that of physical energy storage. With the improvement of the energy system's demand for energy storage technology, physical energy storage technology, which has always been known for its low environmental pollution and high operational stability, is being developed. The temperature rises rapidly, among which the flywheel energy storage has the characteristics of fast charging and discharging, and the highest energy density. The flywheel energy storage system is composed of high-speed flywheel, bearing support system, motor, generator, power converter, electronic control system and additional equipment such as vacuum pump and emergency backup bearing. At v...
