Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see www .iso
.org/iso/foreword .html.
This document was prepared by Technical Committee ISO/TC 22 Road vehicles, Subcommittee SC 37
Electrically propelled road vehicles.
This edition of ISO/TR 8713 cancels and replaces the first edition (ISO 8713:2012), which has been
technically revised and includes the following main changes:
— addition of all terms and definitions from ISO/TC 22/SC 37 standards;
— addition of source information for terms/definitions not developed in ISO/TC 22/SC 37;
— provision of information on standards using the relevant term and defining a master;
— adaptation of structure to the ISO/IEC Directives Part 2, 2016 edition;
— provision of a list of abbreviations used in this document.
Any feedback or questions on this document should be directed to the user’s national standards body. A

Introduction
This document establishes a vocabulary of terms and the related definitions used in ISO standards for
electrically propelled road vehicles.
It provides support for the development of new standards and for the review of existing standards.
This document lists terms as defined in ISO/TC 22/SC 37 publications. For each term, the master
publication is assigned based on an ISO/TC 22/SC 37 decision. Other publications of ISO TC 22/SC 37
may contain definitions for those terms as well. This document replicates the definition for the term
from the master publication without any change. The master publication and the other publications are
listed with each term.
ISO/TC 22/SC 37 decided that project leaders of projects using the term should align themselves with
the content of the definition under the leadership of the project leader from the master publication.
ISO/TC 22/SC 37 prioritizes a consistent use of definitions for terms.
The terms and definitions are listed in alphabetical order. A topic specific list is given in Annex A.
