The automobile design process is faced with increased requirements on electrical energy storage devices. Modeling the battery's behavior is mandatory for simulating the complete power system. This work figures out the main requirements on those models and presents modeling approaches for various purposes and applications afterwards. A time domain model and a frequency domain model map battery's behavior with high accuracy. For taking into account the degradation process different ways for modeling the aging effects are presented. Increased requirements on automotive energy storage devices both for traction and classic SLI functions demand precise knowledge of battery behavior and reliable models for simulating the complete power system. This work describes different modeling approaches. The time domain model maps battery behavior over a wide range of operation parameters with high accuracy and takes into account both long term and high dynamic behavior. The frequency domain model using electrochemical impedance spectroscopy focusses on the battery's complex-valued inner impedance and describes its behavior in a defined operating point. Finally aging influence is investigated systematically in order to extend the time domain model and to predict cycle life in dependence of operating parameters.
