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

What Is Energy Storage? "Storage" refers to technologies that can capture electricity, store it as another form of energy (chemical, thermal, mechanical), and then release it for use when it is needed. Lithium-ion batteries are one such technology. Although using energy storage is never 100% efficient—some energy is always lost in
