The initial integration of a large scale battery system in existing end products like cars is usually of experimental nature. So are the simulation models supporting its design process. In the following a comprehensive Modelica model is introduced for the simulative description of the physical behavior of lithium ion battery cells packs for relevant aspects and use cases. It is part of the Modelon Battery Library; a commercial Modelica library to model battery cells and packs of various types; shape and grouping.
Thermal behavior; electrical behavior and the impact of the degradation due to aging are considered as they influence each other.
The model parameters to calculate the electrical behavior are to be derived from measurements; an optimization algorithm to obtain them is integrated in the package using the Optimization Library. Functions to validate the model against these measurements are included as well.
As an application example the simulation of an energetic energy storage system in the model of a battery electrical vehicle is shown.
