What is a battery energy storage system?
A battery energy storage system (BESS) is an electrochemical device that charges from the grid or a power plant and then discharges that energy to provide electricity or other grid services when needed.
How does the state of charge affect a battery?
The state of charge greatly influences a battery’s ability to provide energy or ancillary services to the grid at any given time. Round-trip efficiency, measured as a percentage, is a ratio of the energy charged to the battery to the energy discharged from the battery.
Can a battery store electricity if not used?
However, batteries are not ideal and due to internal leakage currents or parasitic loads batteries will slowly discharge themselves when not in use but until then they can store electrical energy for very long periods of time. Then we can say that a battery is an energy storage device capable of storing and producing electricity until it is needed.
How long can a battery store and discharge power?
The storage duration of a battery is determined by its power capacity and usable energy capacity. For example, a battery with 1MW of power capacity and 6MWh of usable energy capacity will have a storage duration of six hours.
How does charging a battery work?
Charging a cell or whole battery is effectively the reverse of the discharging process, in that electrical energy is converted into chemical energy which the battery stores until it is needed.
Who uses battery storage?
Battery storage is a technology that enables power system operators and utilities to store energy for later use.
