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.
