SCOPE This SAE Technical I
22、nformation Report SAE J2931/4 establishes the specifications for physical and data-link layer communications using broadband Power Line Communications (PLC) between the plug-In electric vehicle (PEV) and the electric vehicle supply equipment (EVSE) DC off-board-charger. This document deals with the
23、specific modifications or selection of optional features in HomePlug Green PHY v1.1 (HomePlug GP1.1) necessary to support the automotive charging application over Control Pilot lines as described in SAE J1772. PLC may also be used to connect directly to the Utility smart meter or home area network (
24、HAN), and may technically be applied to the AC mains, both of which are outside the scope of this document. 1.1 Purpose The purpose of SAE J2931/4 is to describe the broadband PLC communications component to complement SAE J1772. Specifically, it provides context for HomePlug GP1.1 PLC technology an
25、d specifies specific parameters and methods required to use HomePlug GP1.1 PHY for the automotive charging applications. The use cases for communications between a PEV and the utility are described in SAE J2836/1 with the message details included in SAE J2847/1. The PEV may also interface with an of
26、f-board charger in the EVSE as described in SAE J2836/2 with the messages defined in SAE J2847/2. SAE J2931/1 describes OSI-layers 3 through 6 to interface between the application messages and SAE J2931/4. It is an objective of this document to be harmonized with DIN 70121 and also with ISO/IEC 1511
27、8 and IEC 61851 series documents. 2. REFERENCES 2.1 Applicable Documents The following publications form a part of this specification to the extent specified herein.
