The most significant problem is short range in electrical and hybrid electric vehicles (EV, HEV). There are various studies about higher energy density battery technologies and higher efficient internal combustion engines to overcome range problem. In this study, the kinetic energy storage system designed and experimentally investigated to increase range of EV and HEV with available battery capacity. Traditional vehicles lose their kinetic energy as heat energy when they want to slow down. However, if vehicles do regenerative braking, they can store some part of this kinetic energy in energy storage system. But most of the recuperated energy is lost as heat in braking mode. In this study, a Flywheel Energy Storage System (FESS) is designed to store vehicle�s kinetic energy, which occurs braking of the vehicle. Mathematical calculations, design of the FESS have been done in a scaled down laboratory prototype. Simulation and mechanical production stages of the prototype and preliminary test results are also included in the full paper. Flywheel is an energy storage system that stores the regenerated energy as kinetic energy on a high speed rotating mass. Vehicle�s electric motor is operated as generator during braking. The regenerated energy is transferred to the FESS� Motor/Generator (M/G) unit during deceleration of the vehicle. M/G unit is operated as motor mode and energy is stored as kinetic energy by accelerating the FESS. Then the stored energy transferred the vehicle�s DC bus operating M/G unit as generator mode when vehicle needs energy to accelerate the vehicle. Thus there is no loss of kinetic energy converted into heat energy from the vehicle during breaking, is stored to be used again in FESS.
