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 on the meaning of ISO specific terms and expressions related to conformity
assessment, as well as information about ISO’s adherence to the WTO principles in the Technical
Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information
The committee responsible for this document is ISO/TC 22, Road vehicles, Subcommittee SC 38,
Motorcycles and mopeds.
If there is any lack of requirements especially for safety issues in this International Standard, the
requirement in other relevant standards, such as ISO 17409, is adopted.

Introduction
This International Standard prescribes basic safety requirements for electrically propelled mopeds
and motorcycles, which are called electric vehicles, for simplicity, in this International Standard, while
connected to an external electric power supply. The safety requirements for off-board chargers are
described in IEC 60335-2-29 and will be described in the IEC 61851-3 series (under consideration).
This International Standard does not consider discharging from vehicle to grid.
This International standard does not standardize specific charging method.
Moped and motorcycle are defined in ISO 3833:1977, 3.4 and 3.5.
