Research on Electromagnetic Compatibility of New Energy Vehicles

Abstract

The concept of automotive electromagnetic compatibility (EMC) is introduced. The occurrence of electromagnetic interference is pointed out, which includes interference source, transmission path of interference source and interference sensitive equipment. According to EMC test and design issues of new energy vehicles, test items for the development of new energy vehicles are summarized. The methods to enhance EMC performance and the measures to suppress electromagnetic coupling are presented from the perspective of improving vehicle performance. For the vehicle EMC design, some specific advices are given from wires selecting, wire disposal, grounding, etc. The adoption of these recommendations can effectively reduce vehicle electromagnetic radiation and improve the vehicle electromagnetic immunity performance.
