Title
Use Cases for Communication between Plug-in Vehicles and Off-Board DC Charger
Scope
This SAE Information Report SAE J2836/2<sup>T</sup><sup>M</sup> establishes use cases and general information for communication between plug-in electric vehicles and the DC Off-board charger. Where relevant, this document notes, but does not formally specify, interactions between the vehicle and vehicle operator.<p>This applies to the off-board DC charger for conductive charging, which supplies DC current to the vehicle battery of the electric vehicle through a SAE J1772<sup>T</sup><sup>M</sup> Hybrid coupler or SAE J1772<sup>T</sup><sup>M</sup> AC Level 2 type coupler on DC power lines, using the AC power lines or the pilot line for PLC communication, or dedicated communication lines that is further described in SAE J2847/2.<p>The specification supports DC energy transfer via Forward Power Flow (FPF) from grid-to-vehicle.<p>The relationship of this document to the others that address PEV communications is further explained in section 5.<p>This is the 1st version of this document and completes step 1 effort that captures the initial objectives of the SAE task force. The intent of step 1 was 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.
