You will learn how to implement the EKF in Octave code, and how to use the EKF to estimate battery-cell SOC. The EKF is the best known and most widely used nonlinear Kalman filter. But, it has some ...

SoC is typically expressed as a percentage of a battery’s total energy storage capacity. For example, an SoC of 50% means a battery is half-charged. Accurate and reliable SoC measurement is ...
