The application of electric motors and inverters for automotive traction leads to a significant increase in electromagnetic compatibility (EMC) problems. Especially the influence of traction batteries as part of the path for electromagnetic interference is not sufficiently investigated up to now. In This work, models for battery behavior are derived from the structure of cylindrical and prismatic batteries. Therefore, material parameters are defined which describe the characteristics of the material used in the battery and allow the prediction of current distribution in the battery. The models are parameterized and verified by impedance measurements on Lithium ion (Li-ion) and nickel metal hydride (NiMH) batteries. The results allow the calculation of high frequency losses, the simulation of batteries as interference path and the prediction of external fields.
