Recently, wireless power transfer technology has attracted attention. There is interest in how much physical quantity has been induced in the human body due to typical wireless power transfer system. The most promising frequency band is 85 kHz band. Only a few studies have been reported on the compliance evaluation for this application. According to the international guidelines by international committee on non-ionizing radiation protection (ICNIRP), the dominant factor affecting the human body is nerve stimulation. Thus, the in-situ electric field is used as a metric. The basic restriction (allowable in-situ electric field) at this frequency is 11.475 V/m. In this study, we analyzed the variability of the in-situ electric field for the wireless power transfer system implemented under the central vehicle body with the SPFD (Scalar Potential Finite Difference) method, which is based on the quasi-static approximation. First, we analyzed the distance property of the electric field when human standing at the side of the vehicle. In addition, we conducted computation to examine several postures of human body; scenarios when picking up an object on the ground and when lying, the maximum values of in-situ electric fields were 0.92 and 5.95 V/m, respectively. The induced electric field for the driver in the vehicle and the human standing on the primary coil (without the vehicle body), the maximum in-situ electric field was 0.024 V/m in the hip and 0.549 V/m in the ankle, respectively. All these values were smaller than the basic restriction. |
