Low‐complexity state of charge and anode potential prediction for lithium‐ion batteries using a simplified electrochemical model‐based observer under variable load condition

Abstract: The accurate knowledge of the physics-based state of charge (SOC) and anode potential for lithium-ion batteries (LIBs) plays an essential role in the driving range prediction and charge strategy optimization of electric vehicles (EVs). However, the SOC estimation based on empirical equivalent circuit models and the lack of anode potential information makes it challenging in developing advanced battery management systems for EVs. For this reason, this paper proposes a low-complexity SOC and anode potential pred… Show more

“…The SOH is an important indicator to evaluate the aging state. Currently, the SOH estimation methods have been mainly divided into two categories: model-based methods and data-driven methods (Xiong et al, 2018;Liu F. et al, 2021;Khaleghi et al, 2022;Wu et al, 2022). Among them, the model-based methods mainly include electrochemical methods, empirical methods, and equivalent circuit methods.…”

“…Among them, the model-based methods mainly include electrochemical methods, empirical methods, and equivalent circuit methods. The aging model of the solid electrolyte interphase (SEI) layer is established for the electrochemical method (Tian et al, 2021;Wu et al, 2022). The electrochemical method can not only describe the complex electrochemical reaction but also provide an accurate aging model.…”
