本SAE技术信息报告SAE J2931/4规定了在插入式电动车辆（PEV）和电动车辆供电设备（EVSE）直流非车载充电器之间使用宽带电力线通信（PLC）进行物理和数据链路层通信的规范。本文件涉及HomePlug Green PHY v1.1（HomePlug GP1.1）中可选功能的具体修改或选择，这些功能是支持SAE J1772中所述的控制引导线上的汽车充电应用所必需的™. PLC也可用于直接连接到公用事业智能电表或家庭局域网（HAN），并可在技术上应用于交流电源，这两者都不在本文件的范围内。

This SAE Technical Information 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 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 (HAN), and may technically be applied to the AC mains, both of which are outside the scope of this document.
