Abstract:
This contribution deals with the modeling and validation of multi-physical battery-models, by using the programming language Modelica. The article presents a battery model which can be used to simulate the electric, thermal and aging behavior of a lithium-ion traction battery of an EV in different load conditions.The model is calibrated with experimental data of an electric vehicle tested on a chassis dynamometer. The calibration parameters, that are the open circuit voltage, the serial resistance and the resistance and capacitance of two serially connected RC-circuits, are used to configure the electric equivalent circuit model of the battery. The calibration process is based on a best-fit of the measured data from one test, while the validation is made by comparing measured and simulated battery voltages of a different battery load cycle. The comparison between simulations and experiments shows that this model is capable to accurately reproduce the real-world behavior of the battery, providing the scientific community with a novel approach for design and optimization purposes.
