EMC mapping of a power train for fully electric 4-wheel drive vehicle

EMC issues in electric cars require a significantly different approach to the one in conventional cars due to the new power topologies. As a result, the EMC methodologies in these vehicles are not so much developed as they are for example in the railways case, where compatibility with communications and signaling infrastructure is assessed. This paper presents the results of a EMC study focused on the electromagnetic interferences that take place in a power train system used aboard a fully electrical vehicle. The outcome in this work is part of a EMC approach that covers the analysis of the emissions and immunity characteristics, as well as the coupling phenomena and grounding issues that cause an impact on the system safety and performance. The work herein corresponds to the first stage of the study carried out within the E-VECTOORC project (FP7-INFSO-284078), in collaboration with Jaguar Land Rover and řkoda, whose final step will be the electromagnetic mapping of a complete 4-wheel drive vehicle.
