EMC Analysis of High and Low Voltage Wiring Spacing for New Energy Vehicles

Abstract

With the gradual improvement of vehicle electrification level, the layout and wiring of electrical parts are facing unprecedented challenges. EMC performance becomes a key performance indicator after the continuous compression of the spacing between electrical parts. Especially for new energy vehicles, there are both high and low voltage systems. If the high and low voltage coupling is not handled well, EMC problems will occur frequently. This paper focuses on the EMC analysis of the high and low voltage wiring spacing of new energy vehicles, and makes a comprehensive analysis from the aspects of theory, standard, simulation and test, and gives relevant wiring spacing suggestions.
