Flywheel Energy Storage Systems (FESS) rely on a mechanical working principle: An electric motor is used to spin a rotor of high inertia up to 20,000-50,000 rpm. Electrical energy is thus converted to kinetic energy for storage. For discharging, the motor acts as a generator, braking the rotor to produce electricity.
Braking energy recovery (BER) notably extends the range of electric vehicles (EVs), yet the high power it generates can diminish battery life. This paper proposes an optimization strategy for BER that employs a hybrid energy storage system (HESS), integrating a flywheel energy storage system (FESS) with a battery system.
Therefore, a new type of energy storage device named flywheel system appeared [ 12]. Research data showed that the use of flywheel systems made the energy recovery rate of electric vehicles up to more than 85%, which not only effectively reduced the emission of pollutants but also prolonged the service life of power batteries.
As a solution, the flywheel energy storage system (FESS) can be offered. In the literature, power transmission of vehicles with integrated FESS is provided by mechanical systems (CVT FESS). These systems are heavy, high cost, large volume, and occupy the rear axle of the vehicle.
For braking, a cable winds onto a pulley geared to the vehicle''s propulsion driveshaft as it unwinds from another pulley geared to the flywheel and then operates in reverse for the transfer of
