Konzept zur kabellosen Energieversorgung von Elektrofahrzeugen unter Verwendung eines induktiven Spulensystems - Concept for wireless energy supply of electric vehicles with inductive coil systems

One of the major challenges of today's electric vehicles is its far from satisfactory energy storage capacity. Consequent-ly, the inductive transmission of electric energy is worthwhile to consider. One variation is an inductive coil system embedded in the road. Correspondingly, this article describes possible topologies of primary and secondary coil ar-rangements for inductive charging. Advantages and disadvantages of applicable topologies are discussed on the basis of simulations. The communication-, localization- and identification- solution that were consequently considered are dis-cussed in the following. We intend to encompass the various possible end-to-end communication-paths of all connected components in one solution. Calculations about the amount of data to be expected conclude this article.
