Information exchange for electric vehicle charging roaming service - Part 1: General

SIST EN IEC 63119-1:2025

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.

Low-voltage switchgear and controlgear - Part 9-2: Active arc-fault mitigation systems - Optical-based internal arc-detection and mitigation devices

SIST EN IEC 60947-9-2:2025

This document covers internal arc-fault control devices, hereinafter referred to as IACD, which are intended to: - detect internal arc-faults in low-voltage switchgear and controlgear assemblies, by processing (at a minimum) the optical effect of an internal arc-fault, and - operate mitigation device (either external or combined) in order to minimize the effects of the internal arc-fault (see Figure 1). For the purpose of this document the terms "light" or "optical" covers more than visible spectra. They may cover also, for example, infrared or ultraviolet electromagnetic radiations (see Annex D). For combined-type IACD, this document is considered in addition to the relevant product standard for internal arc-fault mitigation devices (IARD per IEC TS 63107:2020). Compliance to the relevant product standard is mandatory and cannot be claimed by testing to this document alone. NOTE 1 Low-voltage switchgear and controlgear assemblies are usually described by IEC 61439 series. [Figure 1] Therefore, this document covers the following: - internal arc-fault control device (stand-alone, multifunction or combined); - one or more associated sensor(s) used to detect optical effect of the internal arc-fault; - sensor(s), sensing another physical effect, to confirm the fault; - associated or combined mitigation device. An IACD is not intended to trigger under normal operation of low-voltage switchgear and controlgear (i.e. absence of internal arc-fault), including normal arcing associated with operation of disconnecting and switching devices. This document only covers the following methods: - optical detection of the light caused by an internal arc-fault; - optional confirmation of internal arc-fault by line current measurement. Many different conductive materials could be used in LV assemblies (e.g. steel, copper, aluminium). Nevertheless, tests specified in this document are deemed to represent the most critical and challenging conditions for arc-detection and cover all combinations of conductive materials. NOTE 2 Compared to other materials (e.g. steel, aluminium), copper leads to a lower optical radiation energy. The rated voltage of the assembly in which an IACD is installed does not exceed 1 000 V AC. Such devices are designed to be operated and maintained by skilled persons only. This document does not cover: - DC internal arc-fault detection and control; - overcurrent relays; - AFDD (arc-fault detection devices) as defined by IEC 62606; - guidance on installation within assemblies; NOTE 3 The integration of an IACD into an assembly is described in IEC TS 63107. - use with additional measures needed for installation and operation within explosive atmospheres. These are given in IEC 60079 series documents; - requirements for embedded software and firmware design rules; for this subject, the manufacturer is responsible for taking additional safety measures; NOTE 4 IEC TR 63201 describes rules for firmware and embedded software development preventing errors in software. - cybersecurity aspects; for this subject, the manufacturer is responsible for taking additional safety measures; NOTE 5 See IEC TS 63208. - mobile applications. NOTE 6 Even when addressing internal arc-fault mitigation devices, this document does not supersede any other relevant product standard (e.g. IEC 60947-2 or IEC 60947-9-1). NOTE 7 DC arcing fault phenomena are under consideration. Further investigation is needed to comprehend DC arcing phenomena and required sensing.
