General Model and SOC Estimation of Battery

open access: yesInternational Journal of Circuits, Systems and Signal Processing, 2021
Monitoring the battery state is of great importance for the safety and normal of the systems which are powered by batteries. SOC (State of Charge) is one of the most important state parameters of battery. SOC cannot be measured directly. The Kalman filter algorithm is one of the techniques often applied to estimate SOC value.
