Accurately calculating the capacity of battery packs is of great significance to battery fault diagnosis, health evaluation, residual value assessment, and predictive
Battery module and pack testing involves very little testing of the internal chemical reactions of the individual cells. Module and pack tests typically evaluate the overall battery performance, safety, battery management systems (BMS), cooling systems, and internal heating characteristics.
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.
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.
The United States has several sources for performance and testing protocols on stationary energy storage systems. This research focuses on the protocols established by National Labs (Sandia National Laboratories and PNNL being two key labs in this area) and the Institute of Electrical and Electronics Engineers (IEEE).
Module and pack tests typically evaluate the overall battery performance, safety, battery management systems (BMS), cooling systems, and internal heating characteristics. Common performance-based tests include drive-cycles, peak power capability, BMS software validation, and other application-specific characterization
As in previous battery and capacitor test manuals, this version of the manual defines testing methods for full-size battery systems, along with provisions for scaling these tests for modules, cells or other subscale level devices.
