SOC fusion estimation for lithium battery using dual OCV-SOC relationships combined with fractional order extended Kalman filter

Abstract Using a single or averaged OCV-SOC (open circuit voltage VS. state of charge) relationship obtained under charging or discharging condition will deteriorate battery SOC estimation of model-based methods. To address the issues, this paper proposes a novel SOC fusion estimation method conside...
