Comparison of electromagnetic exposure to child and adult from electric vehicle wireless power transmission

It is important to verify the safety of electric vehicle(EV)wireless power transmission for child passengers by studying the electromagnetic exposure difference between the child passengers and the adult passengers.The dielectric parameters of the child passengers’body were calculated under the operating frequency of 85 kHz.Using the finite element simulation software COMSOL Multiphysics,a model was established for the child passengers and adult passengers when the EVs charged by the wireless charging coil.This paper analyzed the distribution of magnetic induction intensity and induced electric field intensity generated on the body and head when the child passengers and adult passengers sat in four different positions.Additionally,the difference between the brain electromagnetic exposure values of children and adults was analyzed and compared with the limits set.The results showed that the electromagnetic exposure was the largest when the passenger sat in the co-driver position.The electromagnetic exposure level of child was slightly higher than that of adult at the same position,and the magnetic induction intensity and induced electric field intensity of both were much smaller than the public electromagnetic exposure recommendation values.
