Aging Trends and Predictive Value of Equivalent Circuit Parameters: The Role of Operating Conditions in Battery State-of-Health Estimation
This study investigates how two-RC equivalent circuit model (ECM) parameters reflect battery aging and contribute to state-of-health (SOH) estimation under different operating conditions. The analysis uses 12,643 measurements from 30 LG HE4 cells aged at 23–45 °C within five state-of-charge (SOC) windows spanning 0–100...
