RATIONALE

This update is to correct the switch orientation for AC V2V hardware option using prox signal. It’s normally closed instead

of normally open for the prox values expected. Additional AC V2L values will be confirmed to make sure they are also

correct.

1. SCOPE

This SAE Recommended Practice establishes the communication for the variety of potential functions for plug-in electric

vehicle (PEV) customers. This includes features for use case items in SAE J2836/3 that may be PEV/customer optional

equipment, such as AC vehicle-to-load (V2L) and AC vehicle-to-vehicle systems. These systems conform to SAE J1772

with variations required to identify to the PEV bidirectional onboard charger (OBC) the mode of operation changes and

output requirements.

SAE has published multiple documents relating to PEV and vehicle-to-grid (V2G) interfaces. The various document series

are listed below, with a brief explanation of each.

SAE J2836 General requirements and use cases. This series is divided into several sections. SAE J2836/1 is for

utility/smart grid messaging. SAE J2836/2 is for direct current (DC) charge control. SAE J2836/3 is for

reverse energy flow. SAE J2836/4 is for diagnostics. SAE J2836/5 is for consumer requirements and the

home area network (HAN). SAE J2836/6 is for wireless charging.

SAE J2847 Functional messaging requirements. This series defines the functional messages required for a given

function. This series is divided into several sections that correspond to SAE J2836 above. SAE J2847/1 is

for utility/smart grid messaging. SAE J2847/2 is for DC charge control. SAE J2847/3 is for reverse energy

flow. SAE J2847/5 is for consumer requirements. SAE J2847/6 is for wireless charging.

SAE J2931 Digital communications for PEVs. This series defines the requirements to enable digital communications

for PEVs. This series is divided into several sections. SAE J2931/1 describes overall requirements.

SAE J2931/4 is wired communications using PLC. SAE J2931/6 is for wireless charging. SAE J2931/7

includes the security for each of these.

SAE J2953 PEV interoperability with electric vehicle supply equipment (EVSE). This series includes the requirements

in SAE J2953/1 and test procedures in SAE J2953/2, for all the previous documents, including SAE J1772’s

control pilot and proximity circuits and functions.

SAE J3072 Interconnection requirements for onboard, utility-interactive inverter systems. This document includes the

requirements for onboard inverters to send/receive the grid signals for V2G functions.

Figure 1 shows the sequencing of these documents and their primary function (e.g., the SAE J2836 and SAE J2847/1

documents start with smart charging, SAE J2836 and SAE J2847/2 then add DC charging, etc.). The intent is to have

subsequent slash sheets complement each other as more functions and features are included. The /6 series of documents

add wireless charging items not already included in the proceeding slash sheets. These are all then included in

interoperability in SAE J2953 and security in SAE J2931/7. SAE J3072 then includes the PEV to grid requirements for V2G

power and communication to match the SAE J2836/3 use cases.
