Capacity defines the energy stored in the system and depends on the storage process, the medium and the size of the system;. Power defines how fast the energy stored in the system can be discharged (and charged);. Efficiency is the ratio of the energy provided to the user to the energy needed to charge the storage system. It accounts for the energy loss during the …
