Application of V2G communication for wireless interoperable power transfer

Abstract

Vehicle to grid (V2G) communication for conductive charge points is already well established for example by the ISO 15118 standard or the Open Charge Point Protocol (OCPP). Recently a wireless interoperable power transfer (WiPT) has been developed by the multi manufacturer research consortium InterOp. Manufacturer independent operation has been reached by a technology independent source definition of the wireless power supply and is described within IEC 61980-3 Annex AA. This WiPT definition also includes command & control as well as safety procedures. The compatibility of the WiPT command & control to the already standardized V2G communication are investigated within this paper.
