Performance Comparaison Of Lithium-Ion Battery Model Parameters Estimation Methods

This study focused on accurately modeling lithium-ion batteries to ensure safety and efficiency. The process involved selecting the Thevenin model for battery characterization and employing three parameter estimation methods: Simulink design optimization, curve fitting, and extraction from experimental data. After analyzing the results, the study concluded that the Simulink design optimization method was the most effective, as it yielded the lowest root-mean-square error, highlighting its importance for accurately estimating battery parameters and enhancing overall system performance.
