An electric battery is a device that transform chemical energy into electric energy in both directions. It serves to store electric energy by transforming electric energy into chemical energy when it is relatively easy/cheap and release (by transforming back chemical energy into electric energy) it when it is relatively expensive or more needed.
Battery are part of battery energy storage system (BESS): a combination of a battery, power inverters, battery management system (BMS) and energy management system EMS. Other components may include: thermal regulation system,fire protection, electric protection, transformers.
