Flywheel batteries for vehicles [PDF]

open access: yesProceedings of the 2002 Workshop on Autonomous Underwater Vehicles, 2002., 2003
Energy storage flywheels are useful in power conditioning applications, i.e. when there is a mismatch between the power generated and the power required by the load. Two examples of this mismatch are a temporal mismatch and a mismatch in magnitude. The use of a flywheel in a hybrid vehicle, for example, permits the engine to be designed to provide only
