Flywheel energy storage
Flywheel energy storage (FES) works by accelerating a rotor to a very high speed and maintaining the energy in the system as rotational energy. When energy is extracted from the system, the flywheel''s rotational speed is reduced as a consequence of the principle of conservation of energy ; adding energy to the system correspondingly results in an
Ah Efficiency
In particular, columbic efficiency (or Ah efficiency) represents the amount of energy which cannot be stored anymore in the battery after a single charge–discharge cycle [23,24], and the discharge efficiency is defined as the ratio between the output voltage (with internal losses) and the open-circuit-voltage (OCV) of the battery [25].
