The motive of this paper is to explore the state of charge (SOC) observer design for lithium-ion batteries (LIBs) with time-varying parameter uncertainties for electric vehicles (EVs) and hybrid electric vehicles (HEVs) using passivity theory for the first time. Based on the construction of the Lyapunov-Krosovkii functional (LKF) and linear matrix inequality (LMI) technique a novel robust state observer criterion is developed for the solvability of LIBs in terms of equivalent circuit mathematical model (ECMM) in the sense that SOC performance, which ensures the optimum performance of LIBs for EV applications. Finally, a fascinating simulation example is demonstrated to show the usefulness and benefits of the proposed approach, and this was demonstrated through a comparison of our results over existing methods in the literature.
