Batteries also play an important role in daily electromagnetic compatibility (EMC) testing and measurement tasks, namely if they are used for powering devices under test (DUT) or measurement equipment. In this paper, we demonstrate the impact of a commercial 9V block battery on the result of a bulk current injection (BCI) test when used to supply optical voltage probes attached to the DUT. To illustrate the battery’s impact by simulation, a 3D model of selfsame is developed based on its actual internal structure and applying state-of-the-art approaches for battery modeling and commercial 3D EM simulation software. The model is validated by comparison of measurement and simulation of DUT voltages and input current during an actual BCI test.
