Abstract

Two equivalent circuit battery models and two battery model characterization methods are examined in this paper. A simple model, consisting of just an open circuit voltage and a series resistance, is compared to a more sophisticated model composed of an open circuit voltage, inductance, resistance, parallel resistance and capacitance, and a Warburg element all connected in series. The equivalent circuit models are then fit to either time or frequency domain test data, and the model performance for both parameterization methods is compared. In the digest the model accuracy is evaluated for a portion of a vehicle drive cycle, while in the final paper the models will be comprehensively evaluated for a range of drive cycle and temperature cases.
