INFORMATION EXCHANGE FOR ELECTRIC
VEHICLE CHARGING ROAMING SERVICE –
Part 1: General
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.
International Standard IEC 63119-1 has been prepared by IEC technical committee 69:
Electric road vehicles and electric industrial trucks.

INFORMATION EXCHANGE FOR ELECTRIC
VEHICLE CHARGING ROAMING SERVICE –
Part 1: General
1 Scope
This part of IEC 63119 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 charge 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.
IEC 63119 (all parts) 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.
IEC 63119 (all parts) 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.
