Product Code:SAE J2847/2
Title:Communication Bbetween Plug-in Vehicles and Off-Board DC Chargers
Issuing Committee:Hybrid - Ev Committee
Scope:This SAE Recommended Practice SAE J2847-2 establishes requirements and specifications 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.This applies to the off-board DC charger for conductive charging, which supplies DC current to the vehicle RESS of the electric vehicle through a SAE J1772鈩?Hybrid coupler or SAE J1772鈩?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. The specification supports DC energy transfer via Forward Power Flow (FPF) from source-to-vehicle. 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 鈥渨hat we think works鈥?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.
