Field test results of interoperable electric vehicle wireless power transfer

To provide a public infrastructure for wireless power transfer (WPT) to electrical vehicles, the ability of interoperable use between infrastructure and vehicle parts of different manufacturers is necessary. Based on the interoperability definition given in IEC 61980-3 (draft) Annex AA several different primary and secondary devices (pickups) have been realized by four manufacturers and have been applied to full electric cars. Experimental results of the interoperability check and field test results of cross manufacturer vehicle operation are presented, proving the usability of the interoperability definition.
