The extended Kalman filter (EKF) has been widely used to estimate the state-of-charge (SoC) of batteries over the past decade. Battery SoC estimation with the EKF is initialized without knowing the true value of the SoC. Thus, it requires a fast convergence rate to provide users with an accurate SoC...
