Abstract
Communication conformance is an essential link to ensure the application of electric vehicle (EV) wireless power transfer (WPT) systems in a public place. It is necessary to standardize the communication interconnection between vehicle assembly (VA) and ground assembly (GA) produced by different device manufacturers in a standardized way, so as to ensure the safe and stable operation of EV WPT systems. This paper introduces conformance requirements and test standard research progress for communication protocols of EV WPT systems, including the conformance test method, conformance test requirements, and conformance test system. In addition, the power transfer process with respect to communication and the communication message format and content between the ground communication service unit (CSU) and in-vehicle unit (IVU) of EV WPT systems are also presented.
