Electric vehicles are typical representatives of new energy vehicle technology applications, which are developing rapidly and the market is huge. Flywheel energy storage systems can be mainly used in the field of electric vehicle charging stations and on-board flywheels.
The operational mechanism of a flywheel has two states: energy storage and energy release. Energy is stored in a flywheel when torque is applied to it. The torque increases the rotational speed of the flywheel; as a result, energy is stored. Conversely, the energy is released in the form of torque to the connected mechanical device .
There are losses due to air friction and bearing in flywheel energy storage systems. These cause energy losses with self-discharge in the flywheel energy storage system. The high speeds have been achieved in the rotating body with the developments in the field of composite materials.
Small applications connected in parallel can be used instead of large flywheel energy storage systems. There are losses due to air friction and bearing in flywheel energy storage systems. These cause energy losses with self-discharge in the flywheel energy storage system.
The basic function of the flywheel is to convert the mechanical energy for the end-use application, which is electrical energy. For this conversion, an electromechanical machine is required which could be a motor/generator set. Generator and motor: When the kinetic energy is being stored, the motor is used to drive the flywheel.
In simple terms, a magnetic bearing uses permanent magnets to lift the flywheel and controlled electromagnets to keep the flywheel rotor steady. This stability needs a sophisticated control system with costly sensors. There are three types of magnetic bearings in a Flywheel Energy Storage System (FESS): passive, active, and superconducting.
