Electrically propelled road vehicles — Safety specifications — Part 1: Rechargeable energy storage system (RESS)

This document specifies safety requirements for rechargeable energy storage systems (RESS) of electrically propelled road vehicles for the protection of persons. It does not provide the comprehensive safety information for the manufacturing, maintenance and repair personnel. NOTE 1 Requirements for motorcycles and mopeds are specified in ISO 13063 and ISO 18243. NOTE 2 Additional safety requirements can apply for RESS that can be recharged by means different from supplying electric energy (e.g. redox flow battery).

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. 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. 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

This document was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 37,
Electrically propelled vehicles.
This third edition cancels and replaces the second edition (ISO 6469-1:2009) and ISO 12405-3:2014,
which have been technically revised.
The main changes compared to ISO 6469-1:2009 and ISO 12405-3:2014 are as follows:
— test descriptions and requirements were reworked to include specific characteristics for lithium-
ion based battery systems;
— document was reworked to become a general safety standard for all RESS types; and
— almost all test procedures and descriptions as given in the previous versions of both documents
have been adapted to the latest technical developments.
A list of all parts in the ISO 6469 series can be found on the ISO website.
Any feedback or questions on this document should be directed to the user’s national standards body. A
