6 FAQs about [User energy storage capacity decay calculation formula]
How is battery degradation calculated?
The battery degradation comes from cyclic and calendar aging. The cyclic aging normally accounts for the C-rate, temperature, DoD usage and No. of cycles. On the other hand, the calendar aging takes into account the SOC, temperature and time. There is no formula as such for the battery degradation calculation.
How do you calculate the end of life of a battery?
The End of Life (EoL) criterion is usually defined as when the battery capacity reduces to 80 % of the rated value, that is: L = 0.2. Battery aging comprises calendar aging and cycle aging. The overall linearized degradation rate fd is then expressed as follows: (2) f d = t f d, t + N f d, c y c l e.
