Wireless Flywheel-Based Fast Charging Station (WFFCS)

To facilitate mass adoption of Electric Vehicles (EVs), fast charging facility deployment is one of the crucial tasks. Flywheel-based Fast Charging Station (FFCS) can be useful in this regard. Flywheel Energy Storage System has advantage of having high power capacity, short access time, long lifetime (cycles), low maintenance effort, high efficiency, and small environmental impacts. Another emerging technology in EV Charging is Wireless power transfer (WPT) or Inductive Power Transfer (IPT). This technology can facilitate static and in-motion charging of electrified transportation. In this paper, FFCS and WPT systems are presented separately with associated control schemes. Lastly a design of Wireless FFCS (WFFCS) has been proposed and implementation challenges are discussed.
