WebThe SOH is often related to the loss of battery’s rated capacity. When the capacity reduces to 80% of the beginning of life capacity, the battery is considered to have reached its end of life. Cycling and calender aging cause the battery to loose its capacity. WebAccurate state-of-charge (SOC) and state-of-health (SOH) estimations of batteries are of great significance for electric vehicles. A combined SOC and SOH estimation method for lithium-ion batteries based on a dual extended Kalman filter (EKF) and fractional-order model (FOM) is proposed. A fractional second-order RC model is established and model …
