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.
SAE J2847-6 defines abstract messages supporting the wireless transfer of energy between EVs and the Wireless Charger/ (WEVSE). This document is based on the use cases in SAE J2836/6™ that established the wireless charging requirements.
