The Effects of Test Profile on Lithium-ion Battery Equivalent-Circuit Model Parameterization Accuracy

Accurate modelling of battery cells is crucial for the safety and longevity of the battery system. The equivalent-circuit battery model (ECM) is widely used because it provides good accuracy at a relatively low computational cost. The accuracy of an ECM depends primarily on the model parameters, which can be identified using optimization algorithms based on experimental data. This study investigates the effect of test profiles on the accuracy …
