电动汽车充电漫游服务信息交换 第1部分：通用要求

[中文适用范围]： IEC 63119-1:2025 RLV 包含官方的IEC国际标准及其红线版本。红线版本仅提供英文版，便于用户快速、直观地比较官方IEC标准与其前一版之间的所有变更。IEC 63119-1:2025为IEC 63119系列的其他部分提供了基础，规定了术语和定义、系统模型的一般描述、分类、信息交换及安全机制，用于电动汽车充电服务提供商（CSP）、充电站运营商（CSO）及清算平台之间的漫游。该标准概述并描述了电动汽车漫游服务系统的一般要求。IEC 63119系列适用于不同CSP之间，以及CSP与CSO之间（通过或不通过清算平台）通过漫游端点进行的信息交换/交互的高层通信。IEC 63119系列不规定充电站（CS）与充电站运营商（CSO）之间，或电动汽车（EV）与充电站（CS）之间的信息交换。本版取消并替代了2019年发布的首版。与前一版相比，本版包括以下重大技术变更：a) 扩展了适用范围，包括区分本地服务提供商和访问服务提供商的角色，并新增了“漫游实体”的明确定义；b) 新增“本地充电服务提供商（home-CSP）”、“访问充电站运营商（visited-CSO）”和“充电详单记录（CDR）”的定义，并扩展了“服务”和“漫游实体”等相关术语；c) 在术语中引入了“home-CSP”和“visited-CSO”的缩写形式，以符合北美和欧洲惯例；d) 更新通信协议栈，采用更新的TLS版本（从1.2升级至1.3）；e) 系统架构和通信接口中包含本地CSP与访问CSO之间的详细交互；f) 新增“服务”的定义，涵盖更广泛的应用，如停车和预约管理；g) 新增“充电详单记录（CDR）”与“服务详单记录（SDR）”之间的区分，并在术语中明确其关系；h) 在通信接口中增强用户凭证传输方法的描述，提供更多样化的描述；i) 在漫游服务模型分类中增强对混合模式的描述，强调通过更快的响应时间提升用户体验。 [外文原描述]： IEC 63119-1:2025 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 63119-1:2025 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 charging 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. The IEC 63119 series 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. The IEC 63119 series 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. This second edition cancels and replaces the first edition published in 2019. This edition includes the following significant technical changes with respect to the previous edition: a) the scope is expanded to include differentiation between home and visited service provider roles and adds an explicit definition of roaming entity; b) adds definitions for "home charging service provider (home-CSP)", "visited charging station operator (visited-CSO)", and "charging detail record (CDR)", and expands related terms such as "service" and "roaming entity"; c) introduces abbreviation variants for "home-CSP" and "visited-CSO" in the terminology, aligning with North American and European conventions; d) updates the communication protocol stack by adopting a newer TLS version (upgraded from 1.2 to 1.3); e) system architecture and communication interfaces include detailed interactions between home-CSP and visited-CSO; f) adds a definition for "service" to cover a broader range of applications such as parking and reservation management; g) adds a distinction between "charging detail record (CDR)" and "service detail record (SDR)" and clarifies their relationship in the terminology; h) enhances the description of user credential transfer methods in communication interfaces with greater diversity; i) enhances the description of the mixed mode in the classification of roaming service models, emphasizing improved user experience through faster response times.
