What drives capacity degradation in utility-scale battery energy
The temperature was assumed to have seasonal changes between 10 and 30 °C and daily changes of ± 5 °C. The SoH of 60% was modelled to be reached after 5 years. The battery degradation in this use case was mainly driven by the cycling ageing (96%), caused by slow but deep cycles. Only 4% of the total capacity loss was caused by calendar ageing.
