Learn MoreA battery energy storage system (BESS) is an electrochemical device that charges (or collects energy) from the grid or a power plant and then discharges that energy at a later time to provide electricity or other grid services when needed.
Depth of Discharge (DOD) is another essential parameter in energy storage. It represents the percentage of a battery's total capacity that has been used in a given cycle. For instance, if you discharge a battery from 80% SOC to 70%, the DOD for that cycle is 10%. The higher the DOD, the more energy has been extracted from the battery in that cycle.
In this blog, we will explore these critical aspects of energy storage, shedding light on their significance and how they impact the performance and longevity of batteries and other storage systems. State of Charge (SOC) is a fundamental parameter that measures the energy level of a battery or an energy storage system.
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.
Rated power capacity is the total possible instantaneous discharge capability (in kilowatts or megawatts ) 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.
The energy storage capacity, E, is calculated using the efficiency calculated above to represent energy losses in the BESS itself. This is an approximation since actual battery efficiency will depend on operating parameters such as charge/discharge rate (Amps) and temperature.
