Are batteries rated in terms of their capacity?
Nearly all batteries, particularly for renewable energy applications, are rated in terms of their capacity. However, the actual energy that can be extracted from the battery is often (particularly for lead acid batteries) significantly less than the rated capacity.
What is the capacity of a battery?
The capability of a battery is the rate at which it can release stored energy. As with capacity, the respective maximum is specified. The common unit of measurement is watts (W), again, with unit prefixes like kilo (1 kW = 1000 W) or mega (1 MW = 1,000,000 W). The C-rate indicates the time it takes to fully charge or discharge a battery.
What is the difference between rated power capacity and storage duration?
Rated power capacity is the total possible instantaneous discharge capability (in kilowatts [kW] or megawatts [MW]) of the BESS, or the maximum rate of discharge that the BESS can achieve, starting from a fully charged state. Storage duration is the amount of time storage can discharge at its power capacity before depleting its energy capacity.
What is the maximum energy accumulated in a battery?
The maximum amount of energy accumulated in the battery within the analysis period is the Demonstrated Capacity (kWh or MWh of storage exercised). In order to normalize and interpret results, Efficiency can be compared to rated efficiency and Demonstrated Capacity can be divided by rated capacity for a normalized Capacity Ratio.
