IEC 63119的本部分为IEC 63119的其他部分奠定了基础，规定了电动汽车充电服务提供商（CSP）、充电站运营商（CSO）和清算所平台之间通过漫游端点漫游的术语和定义、系统模型的一般描述、分类、信息交换和安全机制。概述电动汽车漫游服务系统的一般要求。 IEC 63119（所有部分）适用于涉及不同CSP之间的信息交换/交互的高级通信，以及CSP和CSO之间的信息交换/交互，无论是否通过漫游端点使用交换所平台。 IEC 63119（所有部分）未规定充电站（CS）与充电站操作员（CSO）之间或电动汽车与CS之间的信息交换。交叉引用:RFC 5246IEC 61851-1:2017ISO/IEC 15118-1IEC TS 62913- 2-4:2019IEC 63110-1购买本文件时可获得的所有现行修订均包含在购买本文件中。

This part of IEC 63119 establishes a basis for the other parts of IEC 63119, specifying the terms and definitions, general description of the system model, classification, information exchange and security mechanisms for roaming between EV charge service providers (CSPs), charging station operators (CSOs) and clearing house platforms through roaming endpoints. It provides an overview and describes the general requirements of the EV roaming service system. IEC 63119 (all parts) is applicable to high-level communication involved in information exchange/interaction between different CSPs, as well as between a CSP and a CSO with or without a clearing house platform through the roaming endpoint. IEC 63119 (all parts) does not specify the information exchange, either between the charging station (CS) and the charging station operator (CSO), or between the EV and the CS.Cross References:RFC 5246IEC 61851-1:2017ISO/IEC 15118-1IEC TS 62913-2-4:2019IEC 63110-1All current amendments available at time of purchase are included with the purchase of this document.
