Non-Destructive Modeling of a 9V Alkaline Battery for EMC Simulation Based on S-Parameter Measurement

摘要

Batteries are fundamental components of many modern systems, most prominently electric vehicles (EV) or mobile devices. Hence, generation of battery models is becoming a crucial task to evaluate the performance of suchlike electronic systems in simulation, including electromagnetic compatibility (EMC). But even commercial cells like a 9V block battery may critically impact daily EMC measurement tasks, namely if they are used for powering tested devices or peripheral equipment. To depict the battery’s influence by simulation, a model of selfsame suitable for 3D simulation with commercial software is developed. It is validated by two practical experiments and eventually applied to reproduce results of a bulk current injection (BCI) test.
