how does the magnetic levitation flywheel energy storage battery store electricity

The flywheel energy storage system (FESS) has excellent power capacity and high conversion efficiency. It could be used as a mechanical battery in the uninterruptible power supply (UPS). The magnetic suspension technology is used in the FESS to reduce the standby loss and improve the power capacity.

ESSs store intermittent renewable energy to create reliable micro-grids that run continuously and efficiently distribute electricity by balancing the supply and the load [1]. The ex-isting energy storage systems use various technologies, including hydro-electricity, batteries, supercapacitors

In these systems it is typical to have an electric motor/generator which acts to produce a mechanical torque accelerating the rotational speed of the flywheel as electric power is supplied to it. The same process can be made to work in reverse so that the rotational kinetic energy of the flywheel
