The main technical measures of a Battery Energy Storage System (BESS) include energy capacity, power rating, round-trip efficiency, and many more. Read more...
In residential storage solutions there’s a broad range of batteries available, each with specific energy content. Someone can find two commercial battery storage systems with the same rated energy of 9.8 kWh, but different capacities. Let’s call them System A and System B. Why do they have different capacities but the same rated energy?
Rated Energy Storage Capacity is the total amount of stored energy in kilowatt-hours (KWh) or megawatt-hours (MWh). Capacity expressed in ampere-hours (100Ah@12V for example). The amount of time storage can discharge at its power capacity before exhausting its battery energy storage capacity.
The amount of time storage can discharge at its power capacity before exhausting its battery energy storage capacity. For example, a battery with 1MW of power capacity and 6MWh of usable energy capacity will have a storage duration of six hours. Depth of Discharge (DoD) expresses the total amount of capacity that has been used.
1. Amp-Hours (Ah) Amp-hours (Ah) measure the total energy storage capacity of a battery. This rating indicates how much current a battery can deliver over a specific period. For example, a battery rated at 100 Ah can provide 5 amps for 20 hours before needing a recharge.
A full battery energy storage system can provide backup power in the event of an outage, guaranteeing business continuity. Battery systems can co-locate solar photovoltaic, wind turbines, and gas generation technologies.
