Most of the BESS systems are composed of securely sealed battery packs, which are electronically monitored and replaced once their performance falls below a given threshold. Batteries suffer from cycle ageing, or deterioration caused by charge–discharge cycles. This deterioration is generally higher at high charging rates and higher depth of discharge. This aging cause a loss of performance (capacity or voltage decrease), overheating, and may eventually le
