Protocol for management of electric vehicles charging and discharging infrastructures - Part 1: Basic definitions, use cases and architectures

IEC 63110-1:2022, as a basis for the other parts of IEC 63110, covers the definitions, use cases and architecture for the management of electric vehicle charging and discharging infrastructures.
It addresses the general requirements for the establishment of an e-mobility eco-system, therefore covering the communication flows between different e-mobility actors as well as data flows with the electric power system.
This document covers the following features:
– management of energy transfer (e.g., charging session), reporting, including information exchanges related to the required energy, grid usage, contractual data, and metering data;
– asset management of EVSE, including controlling, monitoring, maintaining, provisioning, firmware update and configuration (profiles) of EVSE;
– authentication/authorization/payment of charging and discharging sessions, including roaming, pricing, and metering information;
– the provision of other e-mobility services;
– cybersecurity.

Protocole de gestion des infrastructures de charge et de décharge des véhicules électriques - Partie 1: Définitions de base, cas d'utilisation et architectures

L'IEC 63110-1:2022, qui sert de base aux autres parties de l'IEC 63110, couvre les définitions, cas d'utilisation et architectures pour la gestion des infrastructures de charge et de décharge des véhicules électriques.
Elle porte sur les exigences générales relatives à la mise en place d'un écosystème de mobilité électrique et couvre donc les flux de communication entre les différents acteurs de mobilité électrique, ainsi que les flux de données avec le système d'alimentation électrique.
Le présent document couvre les caractéristiques suivantes:
– la gestion du transfert d'énergie (session de charge, par exemple), la consignation, y compris les échanges d'informations relatives à l'énergie exigée, l'utilisation du réseau électrique, les données contractuelles et les données de comptage;
– la gestion des actifs du SAVE, y compris le contrôle, la surveillance, la maintenance, l'approvisionnement, la mise à jour du micrologiciel et la configuration (profils) du SAVE;
– l'authentification/l'autorisation/le paiement des sessions de charge et de décharge, y compris les informations d'itinérance, de tarification et de comptage;
– la fourniture d'autres services de mobilité électrique;
– la cybersécurité.

PROTOCOL FOR MANAGEMENT OF ELECTRIC VEHICLES
CHARGING AND DISCHARGING INFRASTRUCTURES –
Part 1: Basic definitions, use cases and architectures
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 63110-1 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:
Draft Report on voting
69/837/FDIS 69/843/RVD

Full information on the voting for its approval can be found in the report on voting indicated in

the above table.
