Communication for Plug-in Electric Vehicles 2012-01-1036

This paper is the third in the series of documents designed to record the progress on the SAE Plug-in Electric Vehicle (PEV) communication task force. The initial paper (2010-01-0837) introduced utility communications (J2836/1™ & J2847/1) and how the SAE task force interfaced with other organizations. The second paper (2011-01-0866) focused on the next steps of the utility requirements and added DC charging (J2836/2™ & J2847/2) along with initial effort for Reverse Power Flow (J2836/3™ & J2847/3). This paper continues with the following: 1. Completion of DC charging's 1st step publication of J2836/2™ & J2847/2. 2. Completion of 1st step of communication requirements as it relates to PowerLine Carrier (PLC) captured in J2931/1. This leads to testing of PLC products for Utility and DC charging messages using EPRI's test plan and schedule. 3. Progress for PEV communications interoperability in J2953/1.
The Use cases, general information and architecture are also being developed and/or updated for the following. 4. Reverse Power Flow (J2836/3™ & J2847/3), 5. Diagnostics (J2836/4™ & J2847/4), 6. Customer to PEV and HAN/NAN communication (J2836/5™ & J2847/5).
The existing approach continues for these documents whereas the J2836™ series to capture the use cases and general information that feeds into the J2847 series with corresponding specific requirements. J2931/1 includes the overall and protocol requirements and J2953 includes the interoperability criteria.
The SAE document partitioning allows the teams to focus on specific functions but also allows combinations that build on each other (e.g., Reverse Power Flow with off-board conversion would include the DC communication requirements and only add the additional criteria for that aspect of Reverse Power Flow (RPF), including architecture variations).
These documents are also expected to progress thru at least three ballot steps with Step 1 being "what we think works," Step 2 "implement and update changes/additions" and Step 3 being a final review and clean-up. However, more intermediate steps may occur as needed. The intent of these standards is to capture the requirements and options that will enable opportunities for the customer to have a better experience with the PEV.
