The C-rate defines how fast a battery can charge or discharge relative to its capacity., 100 kWh battery discharges at 50. . This report describes development of an effort to assess Battery Energy Storage System (BESS) performance that the U. Department of Energy (DOE) Federal Energy Management Program (FEMP) and others can employ to evaluate performance of deployed BESS or solar photovoltaic (PV) +BESS systems. The. . Battery capacity is a critical indicator of lithium battery performance, representing the amount of energy the battery can deliver under specific conditions (such as discharge rate, temperature, and cutoff voltage), usually measured in ampere-hours (Ah). For example: A 2 MW / 4 MWh BESS can continuously deliver 2 MW for 2 hours before it runs empty. Imagine your battery as a water tank – capacity is the total water volume, while discharge time dictates how fast you can drain it.
