Safety testing and certification for energy storage systems (ESS) Large batteries present unique safety considerations, because they contain high levels of energy. Additionally, they may utilize hazardous materials and moving parts. We work hand in hand with system integrators and OEMs to better understand and address these issues.
Typically battery manufacturers only run life cycle tests at 100% or 80% of energy capacity. However utility cycles can also involve depth of discharge cycling that mix moderate (20-30%) depth of discharge combined with many small (<1%) depth of discharge events. Partial state of charge test patterns must be used to augment the full scale depth
The stored energy capacity test is the first test conducted in the baseline test program, which generates data to calculate round trip efficiency (RTE). The response time and ramp rate tests provide the time required for an ESS to change from zero to full charging/discharging rate and hence the ramp rate, which is important in understanding
