Fractional-Order Model-Based State-of-Charge and State-of-Power Estimation with Available-Capacity Feedback for Lithium-ion Batteries

Accurate state-of-charge (SOC) and state-of-power (SOP) estimation requires consistent treatment of voltage dynamics and available-capacity uncertainty. This study couples a fractional-order equivalent circuit model, a fast multi-innovation unscented Kalman filter SOC observer, and a slow capacity estimator. Self-ada...

A Study on SOC Estimation for Lithium-Ion Batteries Based on the FFRLS-PSO-WMIUKF Algorithm

Accurate estimation of SOC for lithium-ion batteries is a very important job in battery management systems, but under complex dynamic operating conditions, model misalignment often happens, and filtering algorithms usually do not make enough use of historical data, so the estimation accuracy is lowered. This paper puts...
