The flywheel schematic shown in Fig. 11.1 can be considered as a system in which the flywheel rotor, defining storage, and the motor generator, defining power, are effectively separate machines that can be designed accordingly and matched to the application. This is not unlike pumped hydro or compressed air storage whereas for …
The anatomy of a flywheel energy storage device. Image used courtesy of Sino Voltaics . A major benefit of a flywheel as opposed to a conventional battery is that their expected service life is not dependent on the number of charging cycles or age. The more one charges and discharges the device in a standard battery, the more it degrades.
