Abstract

Wireless Power Transfer (WPT) technology is one of the most promising application for charging the batteries of electric vehicles. The exposure assessment of human body to the stray electromagnetic fields emitted by WPT devices is a critical issue which can limit the spreading of this technology in everyday life. In this paper, a numerical dosimetric study was carried out to evaluate the electric (E)-field induced in both a homogeneous ellipsoid phantom and in an anatomical human model exposed to a WPT system prototype delivering a power of 560 W, which was previously experimentally characterized. A methodology for the numerical assessment of the E-field induced by WPT system in exposed people was set up in order to obtain reliable dosimetric results, avoiding high computational costs for simulations. Two exposure scenarios were considered employing the anatomical model: the maximum 99thpercentile of the induced E-field value in central nervous system was 0.05 V/m, that is compliant with the basic restriction for general public established in [1]. The maximum current density value in the head was 30 mA/m2; even in this case the compliance with the basic restriction for population in [2] was assured.
