Secondary cells and batteries containing alkaline or other non-acid electrolytes - Sealed nickel-metal hydride cells and batteries for use in industrial applications - Part 1: Performance

IEC 63115-1:2020 specifies the marking, designation, tests and requirements for sealed nickel­metal hydride cells and batteries used in industrial applications, including stationary applications.
When an IEC International Standard specifying test conditions and requirements for cells used in special applications is in conflict with this document, the former takes precedence (e.g. IEC 62675).
The following are some examples of applications that utilize the cells and batteries falling under the scope of this document.
• Stationary applications: telecom, uninterruptible power supplies (UPS), electrical energy storage system, utility switching, emergency power and similar applications.
• Motive applications: fork-lift truck, golf cart, AGV (Automatic Guided Vehicle), railway, and marine, excluding road vehicles.
Since this document covers batteries for various industrial applications, it includes those requirements that are common and minimum to the various applications.
This document applies to cells and batteries. If the battery is divided into smaller units, the smaller unit can be tested as representative of the battery. The manufacturer clearly declares the tested unit. The manufacturer can add functions to the tested unit that are present in the final battery.

Accumulateurs alcalins et autres accumulateurs à électrolyte non acide - Accumulateurs étanches au nickel-métal hydrure destinés à l'utilisation dans des applications industrielles - Partie 1: Performances

L'IEC 63115-1:2020 spécifie le marquage, la désignation, les essais et les exigences applicables aux éléments et batteries d'accumulateurs étanches au nickel-métal hydrure utilisés dans les applications industrielles, y compris les applications stationnaires.
Lorsqu'une Norme internationale IEC spécifiant des conditions d'essai et des exigences pour des éléments destinés à des applications particulières est en contradiction avec le présent document, c'est la publication particulière qui prévaut (par exemple, l'IEC 62675).
Quelques exemples d'applications utilisant les éléments et batteries d'accumulateurs relevant du domaine d'application du présent document sont cités ci-dessous.
• Applications stationnaires: télécommunication, alimentation sans interruption (ASI), système de stockage de l'énergie électrique, commutation de services publics, alimentation de secours et applications similaires.
• Applications mobiles: chariot élévateur à fourche, voiturette de golf, véhicule à guidage automatique (VGA), véhicules ferroviaires et maritimes, à l'exclusion des véhicules routiers.
Le présent document inclut les exigences communes et minimales pour plusieurs applications dans la mesure où elle traite des batteries destinées aux différentes applications industrielles.
Le présent document s'applique aux éléments et batteries d'accumulateurs. Si la batterie est constituée d'unités plus petites, l'une d'elles peut être considérée comme représentative de la batterie entière et être soumise à l'essai en tant que telle. Le fabricant déclare clairement l'unité soumise à l'essai. Le fabricant peut ajouter à cette unité d'autres fonctions présentes dans la batterie finale.

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.

Part 1: Performance
1 Scope

This document specifies the marking, designation, tests and requirements for sealed

nickel-metal hydride cells and batteries used in industrial applications, including stationary

applications.

When an IEC International Standard specifying test conditions and requirements for cells

used in special applications is in conflict with this document, the former takes precedence (e.g.

IEC 62675).

The following are some examples of applications that utilize the cells and batteries falling

under the scope of this document.

• Stationary applications: telecom, uninterruptible power supplies (UPS), electrical energy

storage system, utility switching, emergency power and similar applications.

• Motive applications: fork-lift truck, golf cart, AGV (Automatic Guided Vehicle), railway, and

marine, excluding road vehicles.

Since this document covers batteries for various industrial applications, it includes those

requirements that are common and minimum to the various applications.

This document applies to cells and batteries. If the battery is divided into smaller units, the

smaller unit can be tested as representative of the battery. The manufacturer clearly declares

the tested unit. The manufacturer can add functions to the tested unit that are present in the

final battery.
2 Normative references
