SECONDARY BATTERIES (EXCEPT LITHIUM)
FOR THE PROPULSION OF ELECTRIC ROAD VEHICLES –

Part 4: Safety requirements of nickel-metal hydride cells and modules

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 61982-4 has been prepared by IEC technical committee 21:
Secondary cells and batteries.
The text of this standard is based on the following documents:
CDV Report on voting
21/852/CDV 21/866/RVC

voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

the stability date indicated on the IEC website under "http://webstore.iec.ch" in the data

INTRODUCTION
The electric road vehicles (EV) including hybrid electric vehicles (HEV) begin to diffuse in the
global market with backing from global concerns on CO reduction and clean energy, as well
2
as from relevant technology advancement and cost reduction. Nickel-metal hydride (Ni-MH)
batteries have advantages in cost and balanced performance, and have been used
extensively for EV application, especially for the propulsion of HEV.
This standard provides the safety test procedures and acceptance criteria of Ni-MH batteries
(cells and modules) for EV application in order to evaluate their basic safety performance. For
automobile application, it is important to note the designing diversity of battery packs and
systems, and specific requirements for cells corresponding to each of such designs. Based on
these facts, the purpose of this standard is to provide a basic level of safety test methodology
and criteria with general versatility, which serves a function in common primary testing of cells
or modules to be used in a variety of battery systems.
For specific requirements for the safety of cell differ depending on the system designs of
battery pack or vehicle, final pass-fail criteria of cell are to be based on the agreement
between the cell manufacturers and the customers.

1 Scope
This Part of IEC 61982 specifies test procedures and acceptance criteria for safety
performance of nickel-metal hydride (Ni-MH) secondary cells and modules used for the
propulsion of electric vehicles (EV) including battery electric vehicles (BEV) and hybrid
electric vehicles (HEV).
