ISO 15118-2:2014规定了电池电动汽车（BEV）或插入式混合动力电动汽车（PHEV）与电动汽车供电设备之间的通信。ISO 15118-2:2014中定义的应用层消息集旨在支持从电动汽车供电设备到电动汽车的能量传输。ISO 15118-1包含描述双向能量传输的额外用例元素。这些用例的实现需要对本文定义的应用层消息集进行增强。 ISO 15118-2:2014的目的是详细说明电动汽车（BEV或PHEV）和电动汽车供电设备之间的通信。规定了用于在通信网络中检测车辆并在EVCC和SECC之间启用基于互联网协议（IP）的通信的方面。 ISO 15118-2:2014定义了消息、数据模型、基于XML/EXI的数据表示格式、V2GTP、TLS、TCP和IPv6的使用。此外，它还描述了如何从第3层的角度访问数据链路层服务。ISO 15118中描述了数据链路层和物理层功能- 3.

ISO 15118-2:2014 specifies the communication between battery electric vehicles (BEV) or plug-in hybrid electric vehicles (PHEV) and the Electric Vehicle Supply Equipment. The application layer message set defined in ISO 15118-2:2014 is designed to support the energy transfer from an EVSE to an EV. ISO 15118-1 contains additional use case elements describing the bidirectional energy transfer. The implementation of these use cases requires enhancements of the application layer message set defined herein. The purpose of ISO 15118-2:2014 is to detail the communication between an EV (BEV or a PHEV) and an EVSE. Aspects are specified to detect a vehicle in a communication network and enable an Internet Protocol (IP) based communication between EVCC and SECC. ISO 15118-2:2014 defines messages, data model, XML/EXI based data representation format, usage of V2GTP, TLS, TCP and IPv6. In addition, it describes how data link layer services can be accessed from a layer 3 perspective. The Data Link Layer and Physical Layer functionality is described in ISO 15118-3.
