Emc design for battery electric vehicle (bev) propulsion system

Abstract

Recently, Battery Electric Vehicle (BEV) became a popular research and development area due to new regulations which aim CO2-free transportation and emission limitations by governments. The integration of electric propulsion systems, that basically consist of high-voltage battery unit, inverter, e-machine, charger, DC/DC converter, into today's cars represents a substantial challenge. Due to having High Voltage (HV) wiring harness and components inside BEV, EMC takes its place as a crucial point that must be investigated. In this paper, the authors show an image of electromagnetic environment of BEV propulsion system. Analysis and design of the propulsion system with practical techniques are represented for reducing the electromagnetic interference.
