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.
Battery capacity, typically measured in ampere-hours (Ah) or watt-hours (Wh), indicates the amount of energy a battery can store and deliver under specific conditions. Accurate capacity testing ensures that batteries meet their specified performance metrics, helps predict their lifespan, and identifies potential degradation issues.
Battery capacity estimation is one of the key functions in the BMS, and battery capacity indicates the maximum storage capability of a battery which is essential for the battery State-of-Charge (SOC) estimation and lifespan management.
By simulating the actual charging and discharging process of the battery, the capacity tester can accurately measure the capacity information of the battery. This method is not only highly accurate, but also can comprehensively evaluate the health of the battery, providing strong support for maintenance decisions.
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.
