What is battery capacity testing?
Capacity testing determines the amp-hour capacity of the battery between a set maximum and minimum voltage under at a predetermined discharge rate. The energy capacity, usually in kilowatt-hours (kWh), is the maximum amount of stored energy for a specified discharge rate over a set voltage range.
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.
Can FEMP assess battery energy storage system performance?
This report describes development of an effort to assess Battery Energy Storage System (BESS) performance that the U.S. 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.
What are the KPIs of a battery system?
For battery systems, Efficiency and Demonstrated Capacity are the KPIs that can be determined from the meter data. Efficiency is the sum of energy discharged from the battery divided by sum of energy charged into the battery (i.e., kWh in/kWh out).
What is battery energy storage?
