4 FAQs about Number of charge and discharge cycles of energy storage equipment

What is a charging and discharging cycle?

A charging and discharging cycle of a battery storage system refers to the process of charging the battery from a lower state of charge (SOC) to a higher SOC and then discharging it back to a lower SOC.

How many full charge/discharge cycles should be counted?

Every time step is critical since battery cycle life changes for every unique SOC value. The findings of the analysis indicate that the suggested cycle counting approach counts 38 total full charge/discharge cycles for a 2 MW/1 MWh BESS which is providing frequency response ancillary service within a one-month period.

Should energy storage systems be recharged after a short duration?

An energy storage system capable of serving long durations could be used for short durations, too. Recharging after a short usage period could ultimately affect the number of full cycles before performance declines. Likewise, keeping a longer-duration system at a full charge may not make sense.

Do batteries go through a full 0 - 100% charge - discharge cycle?

However, in real - world applications, batteries rarely go through a full 0 - 100% charge - discharge cycle. Partial cycles, where the battery only charges or discharges a fraction of its total capacity, are much more common. Different battery chemistries have different cycle life characteristics.
