Compared with other ways to store electricity, FES systems have long lifetimes (lasting decades with little or no maintenance; full-cycle lifetimes quoted for flywheels range from in excess of 10 , up to 10 , cycles of use), high (100–130 W·h/kg, or 360–500 kJ/kg), and large maximum power output. The (ratio of energy out per energy in) of flywheels, also known as round-trip efficiency, can be as high as 90%. Typical capacities range from 3 to 13. The operating principle of flywheel energy storage technology is based on the conversion of electrical energy to kinetic energy. Upon drawing excess power by an electric vehicle charging station from the grid or renewable sources, it gives over that energy to a spinning flywheel for storage. [pdf]
