Electromagnetic modeling and performance comparison of different pad-to-pad length ratio for dynamic inductive power transfer

摘要

Several recent research efforts are oriented towards the dynamic inductive power transfer for the charge of electric vehicles during their motion. This possibility presents several open issues that need a solution. The present paper focuses on the analysis of the effects related to the variation of the ratio between the transmitter and the receiver pad lengths with respect to a basic case in which the two pads have the same dimensions. Three cases are analyzed by means of an accurate electromagnetic modeling investigating the power transfer characteristics and the induced losses in the vehicle chassis.
