Nowadays, the global shift towards living a more eco-friendly life is changing the content of vehicles by means of utilizing more and more electric propulsion systems that use high voltage components with safety aspects that may make automotive electromagnetic compatibility (EMC) more difficult. Vehicles with electric propulsion systems, as well as those that use internal combustion engines (ICE) need to comply with certain EMC rules and not overtake an acceptable level of radiated emissions. Compared to ICE vehicles, electric vehicles (EVs) need recharging of the battery after driving and this simple action may cause EMC issues by producing big levels of radiated emissions that are not acceptable for residential, commercial or light industrial environments. Also, while driving, all vehicles have to be compliant with EMC regulations, so that every electric/electronic system and subsystem inside the vehicle or in the proximity of the vehicle, to function as designed and not be harmful or affect in any way human beings or the environment. This study presents the different operating modes an EV should be tested from EMC point of view to check the generated level of radiated emissions. One of the operating modes is “rechargeable energy storage system (REESS) in charging mode coupled to the power grid”. Another one is “other than REESS in charging mode coupled to the power grid”, but this operating mode can be split in two: “driving mode” and “ready to drive mode”. By analyzing the results obtained from performing real radiated emissions tests in a semi-anechoic chamber on an EV will show the differences between different operating modes, different location of the charging inlet and as well as different types of charging cables.
