Research of EMC management plan optimized for fuel cell electric vehicle(FCEV)

Abstract

The electromagnetic characteristics of FCEVs(fuel cell electric vehicles) are much different from the existing combustion engine cars due to the high voltage/current generated by a fuel cell stack which uses a compressed hydrogen gas reacted with oxygen. Moreover, FCEV are equipped with high voltage systems such as motors, inverters, and converters in addition to ordinary electric systems used in existing combustion engine cars. However, there is neither a reference nor a standard for the evaluation of potential hazards due to the safety errors in electric systems of FCEV. Therefore, EMC(Electromagnetic compatibility) management plan for FCEV systems is the most important element to prevent the possible electric functional safety errors. In this paper, a systematic approach in applying the EMC standard for FCEV system is proposed. Firstly, the EMC(Electromagnetic compatibility) management plan optimized for FCEV is suggested. Subsequently, evaluation procedure and consideration for the EMC management plan is introduced.
