"This SAE Recommended Practice SAE J2847-6 establishes requirements and specifications for communications messages between wirelessly charged electric vehicles and the wireless charger. Where relevant@ this document notes@ but does not formally specify@ interactions between the vehicle and vehicle operator. This is the 1st version of this document and captures the initial objectives of the SAE task force. The intent of step 1 is to record as much information on ""what we think works"" and publish. The effort continues however@ to step 2 that allows public review for additional comments and viewpoints@ while the task force also continues additional testing and early implementation. Results of step 2 effort will then be incorporated into updates of this document and lead to a republished version. The next revision will address the harmonization between SAE J2847-6 and ISO/IEC 15118-7 to ensure interoperability. Purpose The primary purpose of SAE J2847-6 is to provide the communication to achieve wireless charging control irrespective of variations in the wireless charging technology employed. SAE J2847-1 identifies the functional messaging for the Plug-In Electric Vehicle (PEV) to connect to the utility for Level 1 2 AC energy transfer. SAE J2847-2 specifies the messages and protocols for DC charging. This document identifies the additional messages for wireless energy transfer to the PEV."
