Description
Extensive systematic measurements concerning magnetic field exposure of persons during the charging of passenger vehicles with electric drive systems were carried out. Areas both inside and outside the vehicles in their immediate vicinity and close to the charging infrastructure were considered. Magnetic fields occurring during conductive charging of electric vehicles were systematically measured and assessed for a variety of different vehicle-to-charging-point combinations, considering all presently relevant modes of AC and DC charging. The measurements showed that reference levels according to EC recommendation 1999/519/EC and ICNIRP 2010 may be locally and temporarily substantially exceeded in accessible areas during AC charging, caused by transient magnetic fields in the initial phase of the charging process (typically in the time interval 2 - 5 seconds after starting the charging). During the stationary phase of charging, which can be assumed from about 10 seconds after starting the charging process, maximum measured magnetic flux densities inside the vehicles were below the reference levels. Directly along the charging cables and at the surface of the charging plug, the reference levels for the general public were slightly exceeded even during the stationary charging phase.
