For a flywheel energy storage, the state-of-charge is directly measurable from the rotor speed. There are four areas where batteries, for the time being, are decidedly better than flywheels: Cost per kWh. Regarding costs, battery prices have decreased significantly in the last decade.
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 input energy for a Flywheel energy storage system is usually drawn from an electrical source coming from the grid or any other source of electrical energy. As more energy is imparted into a flywheel it speeds up as it stores more energy and slows down when it loses the said energy , .
The principle of flywheel energy storage FESS technology originates from aerospace technology. Its working principle is based on the use of electricity as the driving force to drive the flywheel to rotate at a high speed and store electrical energy in the form of mechanical energy.
FESS has been integrated with various renewable energy power generation designs. Gabriel Cimuca et al. proposed the use of flywheel energy storage systems to improve the power quality of wind power generation. The control effects of direct torque control (DTC) and flux-oriented control (FOC) were compared.
As more energy is imparted into a flywheel it speeds up as it stores more energy and slows down when it loses the said energy , . Although, the existing lithium-ion battery has a high energy density but high cost in term of power capacity and less power density. ... ...
