Summary:

This paper is the fourth in the series of documents designed toidentify the progress on the SAE Plug-in Electric Vehicle (PEV)communication task force. - The initial paper (2010-01-0837)introduced utility communications (J2836/1 and J2847/1) andhow the SAE task force interfaced with other organizations. - Thesecond paper (2011-01-0866) focused on the next steps of theutility requirements and added DC charging (J2836/2 andJ2847/2) along with initial effort for Reverse Power Flow(J2836/3 and J2847/3). - The third paper (2012-01-1036)summarized the task force documents and interaction. It alsoincluded the continued testing of PowerLine Carrier (PLC) productsfor Utility and DC charging messages using Electric Power ResearchInstitutes (EPRI) test plan and schedule that were used at EPRI andArgonne National Labs (ANL). It also included a more completesection on Reverse Power Flow that has now expanded to Use casesfor the Plug-In Electric Vehicle (PEV) as a Distributed EnergyResource (DER) that is now published as J2836/3.The purpose of this paper is to provide an update for FastCharging or DC Charging. The documents for DC Level 1 and 2charging have been published and include updates to three existingstandards and the initial release of a fourth. J1772 is thedocument for the EV Supply Equipment (EVSE), architecture andsafety features for both AC and DC charging and was updated toplace DC charging requirements back into it, since previousversions had it removed to focus on AC charging. The Comboconnector was included along with isolation monitoring and control,precharge and additional safety features as part of the latestversion of J1772. J2931/1 is the communication requirementsdocument and it was updated to include additional layers of thecommunication stack and harmonize with effort in ISO/IEC 15118 andDIN 70121 standards. The digital communication used for DC chargingis PowerLine Carrier (PLC) known as HomePlug GreenPHY (HP GP) andis described in the initial release of J2931/4. PLC is a carriersignal on the J1772 control pilot circuit and does not requireadditional terminals or circuits.The publication of these documents also aligns with the ULcertification of the SAE Combo connector so both the standards andthe products are moving into the implementation phase with a solidbase of documentation and equipment.Customers can select different engines such as a V6 or V8 forthe vehicle. The combination of modules and wiring is coordinatedwith these complexities so the vehicle is built correctly. Itshould be the same with on-board chargers and their EV SupplyEquipment (EVSE) so the customer could choose the combination thatmatches their needs. The EVSE could be installed at their home orif desired, the customer could rely on public locations. Off-boardchargers could be included in the home or public EVSE at a varietyof power levels. This paper will identify an approach or tool thatcan be used to develop the customer value based on cost and time ofre-charging both Plug-in Hybrid Electric (PHEV) and BatteryElectric (BEV) types of Plug-in Electric Vehicles (PEV)
