A novel partial element equivalent circuit (PEEC) formulation for solving full-Maxwell’s equations, with piecewise homogeneous\ud and linear conductive, dielectric, and magnetic media, is presented. It is based on the cell method which by using integral variables\ud as problem unknowns is naturally suited for developing circuit-like approaches such as PEEC. Volume meshing allows complex\ud 3-D geometries, with electric and magnetic materials, to be discretized. Electromagnetic couplings in the air domain are modeled\ud by integral equations

In this paper, starting from the experimental experience of the road embedment of a transmitting coil for wireless power transfer, a numerical model of such device is constructed. The model is then used to perform several parametric analyses which aim at investigating the influence of the main electromagnetic parameters of the concrete and the geometrical parameters of the wireless power transfer on the overall behavior of the device. The results of such study allow for providing guidelines for the design of the coil and the choice of the materials for the embedment. Moreover, as a secondary result of the adopted methodology, the electromagnetic characterization of the concrete adopted for the road embedment is obtained.

The present work aims at quantifying how, and how much, the uncertainties on the components and material parameters of a wireless power transfer (WPT) system for the static charge of electric vehicles affect the overall efficiency and functionality of the final produced device. With the aim of considering the perspective of a possible industrial developer, the parameters selected for the uncertainty quantification are chosen to be the capacitance values of the compensation capacitors and the electromagnetic material parameters used for the construction of the magnetic structure of a WPT system, i.e. the parameters of the elements to be purchased. The analysis is based on a standard system among the ones provided by the current SAE J2954 recommended practice.
