On-board flywheels: There are two charging methods for the on-board flywheel battery, one is to use electrical energy as input energy, and the second is to directly drive the flywheel to rotate through the transmission device with mechanical energy (mainly used for braking energy recovery of electric vehicles).
The energy storage facility provided by flywheels are suitable for continuous charging and discharging options without any dependency on the age of the storage system. The important aspect to be taken note of in this regard is the ability of FES to provide inertia and frequency regulation .
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 .
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.
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.
