This approach will use the direct measurement method with EMF measurement during the equilibrium state and the bookkeeping estimating method with the CC method during the discharging state.
(i) More accuracy (ii) Solving nonlinear system
(i) Limited robustness (ii) Linearization error will occur
It employs the KF method to fix the CC method’s initial values. This method yielded an approximation beginning value that convenes a real deal and SOC estimation for the prolonged working duration.
(i) Low power consumption (ii) Self-correcting nature
This combination is used to find the best battery model parameter for calculating SOC with high accuracy. Parameters’ absolute values are converted to dimensionless values about a set of base values.
