本文件规定了电动汽车（EV）（包括电池电动汽车（BEV）和插入式混合动力电动汽车（PHEV））与电动汽车供电设备（EVSE）之间的通信。本文件中定义的应用层消息旨在支持电动汽车和电动汽车供电设备之间的电力传输。 本文件定义了双向功率传输的通信消息和序列要求。 本文件进一步定义了传导充电和无线充电的无线通信要求，以及自动连接设备和充电和控制状态信息服务的通信要求。 本文件旨在详细说明电动车辆通信控制器（EVCC）和供电设备通信控制器（SECC）之间的通信。 指定了用于检测通信网络中的车辆并启用EVCC和SECC之间基于互联网协议（IP）的通信的方面。

This document specifies the communication between the electric vehicle (EV), including battery electric vehicle (BEV) and plug-in hybrid electric vehicle (PHEV), and the electric vehicle supply equipment (EVSE). The application layer messages defined in this document are designed to support the electricity power transfer between an EV and an EVSE. This document defines the communication messages and sequence requirements for bidirectional power transfer. This document furthermore defines requirements of wireless communication for both conductive charging and wireless charging as well as communication requirements for automatic connection device and information services about charging and control status. The purpose of this document is to detail the communication between an electric vehicle communication controller (EVCC) and a supply equipment communication controller (SECC). Aspects are specified to detect a vehicle in a communication network and enable an Internet Protocol (IP) based communication between the EVCC and the SECC.
