Recently, Battery Electric Vehicle (BEV) became a popular research and development area due to new regulations which aim CO 2 -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.

This paper presents a hybrid formulation that combines MoM and edge-based vector FEM to the find the Shielding Effectiveness of an enclosure with an aperture. While the FEM is used to solve EM fields inside the enclosure, the MoM is used to solve the surface integrals related to the aperture field components, using equivalent surface currents. The hybrid method is applied to the enclosure with and without load. Results are compared with the analytical results and good agreement is reported.

In this paper to obtain of electromagnetic field distribution inside loaded enclosure with aperture, we present hybrid formulation which combines method of moments (MoM) and vector finite element method (FEM). While FEM is used for solving electromagnetic fields inside of the enclosure, MoM is used for solving the surface integrals related with the aperture field components using equivalent surface currents. To obtain efficiency of the proposed method, first applied to empty enclosure and the results are validated by comparing with literature. Then the method applied to loaded enclosure Shielding effectiveness, stored electrical energy and dissipated power in load are examined.
