标准摘要
[中文适用范围]： IEC 63119-1:2025 为 IEC 63119 系列标准的其他部分奠定了基础，规定了术语与定义、系统模型概述、分类、通过漫游终端实现不同电动汽车充电服务提供者（CSP）、充电场站运营商（CSO）及结算平台之间 roaming 时的信息交换与安全机制。该标准概述并描述了电动汽车漫游服务系统的总体要求。IEC 63119 系列标准适用于不同 CSP 之间、以及 CSP 与 CSO 之间（无论是否通过结算平台）经由漫游终端进行的高层级信息交换/交互通信。该系列标准不涉及充电场站（CS）与 CSO 之间，或电动汽车（EV）与 CS 之间的信息交换。本第二版于 2019 年发布的第一版被废止并予以替代。本版在技术上较前一版作出以下重要修订：a) 适用范围扩大，明确区分“归属服务提供商”与“访问服务提供商”角色，并新增“漫游实体”的明确定义；b) 新增“归属充电服务提供者（home-CSP）”、“访问充电场站运营商（visited-CSO）”及“充电详单（CDR）”的定义，并扩展了“服务”“漫游实体”等相关术语；c) 在术语中引入 home-CSP 与 visited-CSO 的缩写变体，以与北美和欧洲惯例保持一致；d) 更新通信协议栈，采用更高版本的传输层安全协议（TLS 由 1.2 升级至 1.3）；e) 系统架构与通信接口中细化了归属 CSP 与访问 CSO 之间的交互过程；f) 扩展“服务”定义以涵盖更广泛的应用场景，如停车与预约管理；g) 区分“充电详单（CDR）”与“服务详单（SDR）”，并在术语中阐明二者关系；h) 在通信接口中丰富并细化用户凭证传递方式；i) 在漫游服务模型分类中强化混合模式的描述，强调通过提升响应速度以改善用户体验。 [外文原描述]： 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.
