The optimal parameter identification of lithium-ion (Li-ion) battery models is essential for accurately capturing battery behavior and performance in electric vehicle (EV) applications.
The battery identification parameters are optimised with the use of an Equilibrium Algorithm (EA) (Shaheen et al., 2021). These algorithms explore the parameter space to find the best-fit values that minimize the discrepancy between the model predictions and the observed battery behavior.

The physics-based lithium-ion battery model used in this work to demonstrate the OED methodology is based on the work of Doyle, Fuller and Newman . However, the proposed optimal parametrization strategy is not limited to this specific model but instead widely applicable for electrochemical battery models and beyond.
The identified optimal parameter values are used to simulate battery behavior, and the results are compared against the actual battery performance during the drive cycle. This validation process assesses the strategy's capability to accurately capture battery behavior and predict performance in EV applications.
The mean objective of the results is estimate the battery parameters to posteriorly use the battery model to estimate the SoC by adaptive method. As results, after the estimation of each parameter, it is possible to observe the resistances exponential behavior, where they decrease as SoC decrease.
