Research on electromagnetic compatibility performance of new energy bus CAN network

Abstract

The application of CAN technology on new energy bus is introduced, focusing on the research of electromagnetic compatibility performance based on CAN network communication reliability. The main sources of electromagnetic interference are discussed. Electromagnetic emission requirements of main interference components and electromagnetic immunity performance requirements of each node of the network are brought out ; Analyzing electromagnetic interference coupling pathways, the basic method is proposed to solve the general interference fault; Further research in the vehicle CAN network topology design , shield and bus layout of CAN node is implemented to ensure the new energy bus CAN network information in timely and effective interaction.I.
