State of Charge Estimation of Lithium-Ion Battery Considering Operating Conditions and Aging Degree

State of Charge Estimation of Lithium-Ion Battery Considering Operating Conditions and Aging Degree

When using the extended Kalman filter (EKF) to estimate the state of charge (SOC) of an electric vehicle power battery, the change of system noise and model parameters may lead to a reduction in estimation accuracy, due to variable operating conditions, battery aging, and other factors. The NCR18650...
