Electricity stored in a flywheel
Kinetic Power Booster is a flywheel-based energy storage system without the need for chemical battery cells. This technology makes it possible to charge electric cars with double the charging power the electricity grid could provide. What''s more, it can be used in places where the grid''s capacity falls far short of what''s required for
A comprehensive review on energy storage in hybrid electric vehicle
The Porsche 918R hybrid concept sports car with a flywheel storage system was announced in the 2010 Detroit Motor show (Amiryar and Pullen, 2017). The FESS stores KE from rotation, where the stored energy E n depends on the moment of inertia ( J ) and the rotational speed ( ω ) ( De Oliveira, 2011 ).
