Scope
SAE J2847/6 establishes minimum requirements for communication between an electric vehicle and an inductive battery charging system for wireless power transfer (WPT). Where relevant, this document notes—but does not formally specify—interactions between the vehicle and vehicle operator.
This document leverages the work of the SAE J2954 Alignment and Controls Sub-Team in the Wireless Power Transfer and Alignment Task Force by extending a JSON-based message set (protocol) originally developed to bench test wireless energy transfer interoperability between unmatched Ground Assembly (GA) and Vehicle Assembly (VA) systems (i.e., components manufactured by different companies). SAE J2847/6 furthers that work by adding messages sufficient to indicate that proper coil alignment has been achieved, initialize the sub-systems for wireless charging, ramp-up to full power, perform active wireless power transfer, and terminate the WPT session.
Guidance for an engineering implementation of the JSON protocol is provided as a reference for developing verification and validation of test plans by enabling the GA and VA to transmit a basic set of information using standard wireless IEEE 802.11n (Wi-Fi) communications hardware.
Rationale
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.

* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
