Comparison of electrical battery models using a numerically optimized parameterization method

This article describes the parameterization process of dynamic battery models for cell and system simulation. Three commonly used equivalent circuit battery models are parameterized using a numeric optimization method and basic electrical tests with a lithium-ion polymer cell. The maximum model performance is investigated and a reasonable simplification is presented. The parameterized models are then validated and compared using a current profile obtained from an electric vehicle simulation performing a real life driving cycle.
