Description / Abstract:
This SAE Information Report SAE J2836/2™ establishes use cases
and general information 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 battery of the
electric vehicle through a SAE J1772™ Hybrid coupler or SAE J1772™
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 that is further described in SAE J2847/2.
The specification supports DC energy transfer via Forward Power
Flow (FPF) from grid-to-vehicle.
The relationship of this document to the others that address PEV
communications is further explained in section 5.
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 "what we
think works" 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.
Purpose
The purpose of SAE J2836/2™ is to document the general
information which must be supported by SAE Recommended Practice SAE
J2847/2, Communication between Plug-in Vehicles and the
off-board charger in the EV Supply Equipment (EVSE).
