What is the difference between rated power capacity and storage duration?
Rated power capacity is the total possible instantaneous discharge capability of a battery energy storage system (BESS), or the maximum rate of discharge it can achieve starting from a fully charged state. Storage duration, on the other hand, is the amount of time the BESS can discharge at its power capacity before depleting its energy capacity.
What does A 2C battery charge rate mean?
For instance, a C/2 rate means that the battery would be fully charged or discharged in 2 hours, while a 2C rate indicates that it would take only 0.5 hours (30 minutes) to charge or discharge the battery. Here are a few examples to illustrate the concept:
What is rated energy storage capacity?
Rated Energy Storage Capacity is the total amount of stored energy in kilowatt-hours (KWh) or megawatt-hours (MWh). It can also be expressed in ampere-hours (e.g., 100Ah@12V). This capacity determines the amount of time storage can discharge at its power capacity before exhausting its battery energy storage capacity.
