Exposures representative of traction current magnetic fields in hybrid and electric vehicles - I: Simulation of basic restrictions in a seated human

Numerical simulations based on an anatomically detailed human model exposed to low frequency magnetic fields that are representative of traction currents in vehicles with electrical powertrains have been used to assess exposure levels for vehicle occupants. The results obtained, which were based on a measured traction current waveform from a small electric vehicle, indicate that induced current density and internal electric fields at frequencies below 3 kHz would comply with the basic restrictions recommended by ICNIRP in 1998 and 2010. However, the estimated exposure relative to the basic restrictions of ICNIRP 2010 is found to be slightly higher than the estimated exposure relative to the corresponding field reference levels in one of the test cases studied.
