Secondary batteries (except lithium) for the propulsion of electric road vehicles - Part 4: Safety requirements of nickel-metal hydride cells and modules

IEC 61982-4:2015 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). This standard intends to secure the basic safety performance of the cell as used in a battery system under intended use and reasonably foreseeable misuse, during the normal operation of EV. The safety requirements of the cell in this standard are based on the premise that the cells and modules are properly used in a battery pack and system within the limit of voltage, current and temperature as specified by the cell manufacturer. The evaluation of the safety of batteries during transport and storage is not covered by this standard.

Accumulateurs (excepté lithium) pour la propulsion des véhicules routiers électriques - Partie 4: Exigences de sécurité pour les éléments et modules d'accumulateurs nickel métal-hydrure

L'IEC 61982-4:2015 spécifie les procédures d'essai et les critères d'acceptation pour les performances de sécurité des éléments et modules d accumulateurs nickel métal-hydrure (Ni-MH) utilisés pour la propulsion des véhicules électriques (EV), y compris les véhicules électriques à batterie (BEV) et les véhicules électriques hybrides (HEV). La présente norme entend encadrer les performances de sécurité fondamentale de l'élément tel qu'il est utilisé dans un système de batterie en utilisation prévue et en utilisation abusive raisonnablement prévisible, pendant le fonctionnement normal du véhicule électrique. Les exigences de sécurité de l'élément dans la présente norme sont basées sur l'hypothèse que les éléments et les modules sont correctement utilisés dans un système et un bloc de batterie dans les limites de tension, de courant et de température telles que spécifiées par le fabricant de l'élément. L'évaluation de la sécurité des batteries pendant le transport et le stockage n'est pas couverte par la présente norme.

Sekundarne baterije (z izjemo litijevih) za pogon električnih cestnih vozil - Varnostne zahteve za nikelj-kovinske hidridne celice in module

Ta del standarda IEC 61982 določa preskusne postopke in kriterije sprejemljivosti za varnostne lastnosti sekundarnih nikelj-kovinskih hidridnih (Ni-MH) celic in modulov, ki se uporabljajo za pogon električnih vozil (EV), vključno z električnimi akumulatorskimi vozili (BEV) ali hibridnimi električnimi vozili (HEV). Ta standard je namenjen za zagotavljanje osnovnih varnostnih lastnosti celice v baterijskem sistemu v skladu s predvideno uporabo in pod pogoji pričakovane nepravilne uporabe pri običajnem delovanju električnih vozil. Varnostne zahteve za celico v tem standardu temeljijo na predpostavki, da se celice in moduli pravilno uporabljajo v baterijskem paketu ter sistemu znotraj napetostnih, tokovnih in temperaturnih omejitev, ki jih določi proizvajalec celic. Ta standard ne vključuje ocene varnosti za baterije med prevozom in skladiščenjem. OPOMBA 1: Celice Ni-MH v tem standardu pomenijo zatesnjene nikelj-kovinske hidridne celice: to so zatesnjene celice, pri katerih se za pozitivno elektrodo uporablja nikljev hidroksid, za negativno elektrodo zlitina, ki absorbira vodik, in za elektrolit alkalna vodna raztopina, kot je kalijev hidroksid. Zatesnjene celice so celice, ki so zmožne ohranjati zatesnjeno stanje ter ne puščajo plina ali tekočine pri električnem polnjenju in praznjenju znotraj temperaturnega razpona, ki ga določi proizvajalec celic. Te celice so opremljene z mehanizmom za izpust plina, ki preprečuje eksplozijo.
OPOMBA 2: V tem standardu se za preskušani modul uporabljajo vsi opisi celic.

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:

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

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.
