Flywheel Energy Storage Systems (FESS) convert electricity to kinetic energy, and vice versa; thus, they can be used for energy storage. High technology devices that directly use mechanical energy are currently in development, thus this scientific field is among the hottest, not only for mobile, but also for stationary applications.
Indeed, the development of high strength, low-density carbon fiber composites (CFCs) in the 1970s generated renewed interest in flywheel energy storage. Based on design strengths typically used in commercial flywheels, s. max/r is around 600 kNm/kg for CFC, whereas for wrought flywheel steels, it is around 75 kNm/kg.
How it works. Very simply the system comprises a flywheel connected by a continuously variable transmission [CVT] to the drivetrain. If you move the CVT toward …
As soon as the desired flywheel speed is reached, the ICE is shut down and the flywheel is used to drive the vehicle, thus the ICE operates in an on-off mode. From 55 kph to 100 kph the ICE is always running and the flywheel assists the vehicle. Beyond that the flywheel is disconnected and ICE powers the vehicle.
