Flexible secondary pad design for wireless power transfer providing public interoperability

To provide a public infrastructure for wireless power transfer (WPT) of electrical vehicles, the ability of interoperable use between infrastructure and vehicles of different manufacturers is necessary. For that reason a Wireless interoperable Power Transfer (WiPT) definition has been conceived and developed for pilot field operation. Due to its ability of interoperable use and being inherently safe, the IEC 61980-3 (TS) Annex AA [3] uses this concept for public under floor installations. One of the main features of WiPT is the wide ranging flexibility for the design of vehicle pads. The concept of reaching this feature and corresponding secondary device design procedures are described.
