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.

Part 1: Performance

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.
This consolidated version of the official IEC Standard and its amendment has been
prepared for user convenience.
IEC 63115-1 edition 1.1 contains the first edition (2020-01) [documents 21A/716/FDIS
and 21A/720/RVD] and its amendment 1 (2022-11) [documents 21A/811/FDIS and
21A/820/RVD].
In this Redline version, a vertical line in the margin shows where the technical content
is modified by amendment 1. Additions are in green text, deletions are in strikethrough
red text. A separate Final version with all changes accepted is available in this
publication.

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.

SEALED NICKEL-METAL HYDRIDE CELLS AND
BATTERIES FOR USE IN INDUSTRIAL APPLICATIONS –

Part 1: Performance

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
The following documents are referred to in the text in such a way that some or all of their
content constitutes requirements of this document. For dated references, only the edition
cited applies. For undated references, the latest edition of the referenced document (including
