Human Exposure to Wireless Charging Systems for Electric Vehicles in Multistorey Carpark

This paper presents a study on the in-situ electric field strength inside the human body due to the exposure to low-frequency magnetic field generated by the wireless charging system (WCS) for electric vehicle inside a multistorey carpark. As the permeability of concrete is the same as that of air, the magnetic field generated by the WCS will penetrate through the floor under the primary coil, and hence result in an intense magnetic field downstairs. In this paper, the magnetic field strength, as well as the induced electric field strength inside a human body standing downstairs, are numerically assessed; the effect of the steel rebars on the dosimetry quantities is also investigated.
