Abstract

In this paper a modeling approach for Lithium-Ion cell online monitoring and offline benchmarking is proposed. It combines physical modeling in equivalent electric circuit representation with grid tables of cell type characteristic information from laboratory tests. The model is fully parameterized and validated with cells used in the HighVoltage battery pack of DLR research robotic electric vehicle ROboMObil.
