SAFETY REQUIREMENTS FOR SECONDARY
BATTERIES AND BATTERY INSTALLATIONS –
Part 6: Safe operation of lithium ion batteries in traction applications
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 62485-6 has been prepared by IEC technical committee 21:
Secondary cells and batteries.
The text of this International Standard is based on the following documents:
FDIS Report on voting
21/1071/FDIS 21/1077/RVD

The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to
the specific document. At this date, the document will be
• reconfirmed,
• withdrawn,

SAFETY REQUIREMENTS FOR SECONDARY
BATTERIES AND BATTERY INSTALLATIONS –
Part 6: Safe operation of lithium ion batteries in traction applications
1 Scope
This part of IEC 62485 applies to battery installations used for electric off-road vehicles; it does
not cover the design of such vehicles.
Examples of the main applications are:
– industrial
• cleaning machines,
• trucks for material handling, for example, lift trucks, tow trucks, automatic guided
vehicles,
• electrically propulsed lifting platforms;
– other applications
• electric powered boats and ships.
This document covers the safety aspects of battery installations in such applications. This
document does not cover railway vehicles, for traction railway application, see IEC 62928.
This document does not cover batteries and battery installations for the propulsion of electric
road vehicles. In the event of there being a variation of requirements between this document
and those of a relevant product standard (e.g. goods vehicles, bicycles, wheel chairs, golf
carts), then the product standard requirements take precedence.
Lithium ion cells and batteries used in traction industrial application are intended to fulfil safety
requirements in accordance with IEC 62619.
The maximum voltages are limited to AC 1 000 V and to DC 1 500 V, and the principal measures
for protection against hazards, generally from electricity, gas emission and electrolyte to
prevent fire and explosion are described.
This document provides requirements on safety aspects associated with the installation, use,
inspection, maintenance and disposal of lithium ion batteries. Batteries containing lithium metal
are not covered by this document.
In general, the safety requirements for secondary batteries and battery installations – General
safety information and definitions are specified for lead-acid, nickel-cadmium and nickel-metal
hybrid batteries in accordance with IEC 62485-1.
