車両2台を対象とした非接触給電システムからの磁界曝露に伴う体内誘導電界の評価

Recently, technology of wireless power transfer (WPT) system for EV/PHV has been developed for the purpose of facilitating the battery charging. However, it is required that we grasp the influence on human health by exposure to leaked magnetic field from WPT system. ICNIRP guideline makes a recommendation that the induced electric field in human body is used for assessment of human safety. In this paper, the value of this quantity is evaluated for different parking patterns of two vehicles. Here, transfer power and frequency are 3.7kW and 85kHz, respectively. As a result of analysis, we found that the value could be reduced by controlling the phase difference between primary currents of two vehicles for each parking pattern.
