SIST EN IEC 63119-2:2023

Information exchange for electric vehicle charging roaming service - Part 2: Use cases (IEC 63119-2:2022)

The Standard specifies roaming use cases of information exchange between EV Charge Service Providers (CSP), Charging Station Operators (CSOs) and Clearing House platforms through roaming endpoints. The elementary use cases defined in this document of IEC 63119-2 are designed to support the user to have access to the EV supply equipment which doesn’t belong to the Home-CSP.
IEC 63119 series are applicable to high-level communication involved in information exchange/interaction between different CSPs, as well as between a CSP and CSO with or without Clearing House platform through the roaming endpoint.
IEC 63119 series do not specify the communication either between Charging Station (CS) and Charging Station Operator (CSO) or between EV and CS.

Échange d'informations pour le service d'itinérance de la recharge des véhicules électriques - Partie 2: Cas d'utilisation (IEC 63119-2:2022)

L'IEC 63119-2:2022 spécifie les cas d'utilisation en itinérance de l'échange d'informations entre les prestataires de services de recharge (CSP, Charging Service Providers) de VE, les opérateurs de bornes de charge (CSO, Charging Station Operators) et les plateformes d'échanges de données par le biais d'un nœud final d'itinérance. Les cas d'utilisation élémentaires définis dans le présent document sont conçus pour aider l'utilisateur à accéder au système d'alimentation pour VE qui n'appartient pas au CSP contractuel.
L'IEC 63119 (toutes les parties) s'applique aux communications de haut niveau dans le cadre des échanges d'informations/interactions entre les différents CSP, mais aussi entre un CSP et un CSO avec ou sans plateforme d'échange de données par le biais du nœud final d'itinérance.
L'IEC 63119 (toutes les parties) ne spécifie pas la communication entre la borne de charge (CS, Charging Station) et l'opérateur de bornes de charge (CSO) ni entre le VE et la CS.

Izmenjava informacij za gostovanje storitev napajanja električnih vozil - 2. del: Primeri uporabe (IEC 63119-2:2022)

Standard določa primere uporabe gostovanja pri izmenjavi informacij med ponudniki storitev polnjenja električnih vozil (CSP), operaterji polnilnih postaj (CSO) in platformami Clearing House prek končnih točk gostovanja. Primeri osnovne uporabe, opredeljeni v tem dokumentu standarda IEC 63119-2, so zasnovani tako, da so uporabniku v pomoč pri dostopu do opreme za napajanje električnih vozil, ki ne spada v Home-CSP.
Skupina standardov IEC 63119 se uporablja za komunikacijo na visoki ravni, ki poteka pri izmenjavi podatkov/interakcijami med različnimi ponudniki storitev napajanja, pa tudi med ponudniki storitev napajanja in operaterji polnilnih postaj s platformami Clearing House prek končnih točk gostovanja ali brez njih.
Skupina standardov IEC 63119 ne določa komunikacije med polnilno postajo (CS) in operaterjem polnilne postaje (CSO) ali med električnim vozilom in polnilno postajo.

Part 2: Use cases

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
IEC 63119-2 has been prepared by IEC technical committee 69: Electrical power/energy
transfer systems for electrically propelled road vehicles and industrial trucks. It is an
International Standard.
The text of this International Standard is based on the following documents:
