This SAE Recommended Practice SAE J2847-2 establishes requirements and specifications for communication between Plug-in Electric Vehicle (PEV) and the DC Off-board charger. Where relevant, this document notes, but does not formally specify, interactions between the vehicle and vehicle operator.<\/div>\n
This document applies to the off-board DC charger for conductive charging, which supplies DC current to the Rechargable Energy Storage System (RESS) of the electric vehicle through a SAE J1772\u2122 coupler. Communications will be on the SAE J1772 Pilot line for PLC communication. The details of PowerLine Communications (PLC) are found in SAE J2931\/4.<\/div>\n
The specification supports DC energy transfer via Forward Power Flow (FPF) from source to vehicle.<\/div>\n
SAE has published multiple documents relating to PEV and vehicle-to-grid interfaces. The various document series are listed below, with a brief explanation of each.<\/div>\n
Figure 1.1<\/span> shows the sequencing of these documents and their primary function (e.g., the J2836 and J2847\/1 documents start with Smart Charging, J2836 and J2847\/2 then adds DC charging, etc.). The intent is to have subsequent slash sheets complement each other as more functions and features are included. The \/6 series of documents add wireless charging items not already included in the proceeding slash sheets. These are all then included in Interoperability in SAE J2953 and security in SAE J2931\/7. J3072 then includes the PEV to grid requirements for Vehicle to Grid (V2G) power and communication to match J2836\/3 Use Cases.<\/div>\n
The summary of documents for DC Charging is then as follows:<\/div>\n
    \n
  1. \n
    SAE J1772\u2122 is the PEV to EVSE systems document and includes the system and timing diagrams for DC Charging<\/div>\n<\/li>\n
  2. \n
    SAE J2836\/2\u2122 starts with the Use Cases for DC Charging communications<\/div>\n<\/li>\n
  3. \n
    SAE J2847\/2 then transforms these Use Case requirements into the signals and messages<\/div>\n<\/li>\n
  4. \n
    SAE J2931\/1 is where the Protocol requirements are placed for all PEV communications<\/div>\n<\/li>\n
  5. \n
    SAE J2931\/4 is used for the PLC communication requirements for DC Charging since it is only a wired median<\/div>\n<\/li>\n
  6. \n
    SAE J2953\/1 is the Interoperability requirements<\/div>\n<\/li>\n
  7. \n
    SAE J2953\/2 is the Interoperability procedure and plan<\/div>\n<\/li>\n
  8. \n
    SAE J2931\/7 includes the security<\/div>\n<\/li>\n<\/ol>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
