Lithium-Ion Battery Degradation & SOH Calculator

Model multi-factor capacity degradation across utility-scale BESS and data center UPS systems: combine Arrhenius electrochemical calendar aging ($k_{cal} propto e^{-E_a / R T}$) and mechanical cycle fade ($k_{cyc} propto sqrt{N}$), project exact years to $80%$ State of Health (SOH) battery retirement, and battery financial modeling yields.
