Abstract

For the characterization, simulation and diagnosis of batteries, different methods can be used. One approach is the separation of static and dynamic behavior, to analyze it separately and to combine them into one model. The dynamic behavior is often characterized by pulse tests and spectroscopic methods. The static behavior is determined by measuring the open circuit potential at different state of charge and temperature. To be useful in an application the measured behavior must be converted into suitable models. The models should be valid over a wide operating range and applicable with only minimal loss of generality. These requirements can be met by nonparametric models. In this work nonparametric modeling of the open circuit potential as well as of the dynamic behavior is presented. Simulations were done and compared to measured results.
