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.
