ADVANCED MODELING APPROACHES FOR STATE-OF-CHARGE ESTIMATION AND STATE-OF-HEALTH MONITORING IN LITHIUM-ION BATTERIES FOR ELECTRIC VEHICLES

Abstract

Abstract: This work reviews battery modeling approaches for electric vehicles, focusing on monitoring State of Health and estimating State of Charge. Key modeling strategies including electrochemical, equivalent circuit, mathematical, and data-driven methods are discussed in terms of their advantages and limitations. Accurate models enable reliable state estimation, enhance battery safety, optimize charging and discharging, and support extended battery life, making them essential for efficient Battery Management Systems and sustainable transport operation.
