Description / Abstract:
This SAE Information Report SAE J2836/6TM establishes
use cases for communication between plug-in electric vehicles and
the EVSE, for wireless energy transfer as specified in SAE J2954.
It addresses the requirements for communications between the
on-board charging system and the Wireless EV Supply Equipment
(WEVSE) in support of detection of the WEVSE, the charging process,
and monitoring of the charging process.
Since the communication to the charging infrastructure and the
power grid for smart charging will also be communicated by the
WEVSE to the EV over the wireless interface, these requirements are
also covered. However, the processes and procedures are expected to
be identical to those specified for V2G communications specified in
SAE J2836/1.
Where relevant, the specification notes interactions that may be
required between the vehicle and vehicle operator, but does not
formally specify them. Similarly communications between the
on-board charging sub-system and the on-board vehicle electronics
is not formally specified in this document.
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 J2836/6TM is to specify the use
cases and communications requirements that will allow access and
control to wireless EV charging systems that comply with SAE J2954,
independent of the precise technology used in implementing the
wireless charging system.
SAE J2847/6 specifies the functional messaging required to
support the use-cases and required in this document.
SAE J2931/6 specifies and profiles the protocols that will be
used to communicate the messages between the EV and WEVSE.
