Revisiting the State of Charge Estimation for Lithium-Ion Batteries A Methodical Investigation of the EKF Approach

This article is devoted to nonlinear state and parameter estimation problems where the system is represented in the state-space framework. This article comprises of two parts where the first part provides a tutorial on prevailing nonlinear stochastic estimation techniques, and the second part presents a self-contained description of estimation problems and solutions in rechargeable Lithium-ion batteries.
