Abstract

This paper investigates how different battery models perform in terms of battery dynamics and state-of-charge (SOC) estimation. We have selected Shepherd and equivalent circuit models to represent the battery pack of lithium-ion batteries in electric vehicles (EVs). We generate the power demand using existing driving cycles to discharge the battery. We conclude that the EC model captures the dynamics of the battery more accurately than the Shepherd model. Nevertheless, both models produce similar results when we assess the SOC estimation.
