Secondary cells and batteries containing alkaline or other non-acid electrolytes - Safety requirements for secondary lithium cells and batteries, for use in industrial applications
This document specifies requirements and tests for the safe operation of secondary lithium cells
and batteries used in industrial applications, including stationary applications.
When there exists an IEC International Standard specifying test conditions and requirements
for cells used in special applications and which is in conflict with this document, the former
takes precedence (e.g., IEC 62660 series on road vehicles).
The following are some examples of applications that utilize cells and batteries 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: forklift truck, golf cart, automated guided vehicle (AGV), railway
vehicles, and marine vehicles, with the exception of road vehicles.
Since this document covers batteries for various industrial applications, it includes those
requirements which are common and minimum to the various applications.
Electrical safety is included only as a part of the risk analysis of Clause 8. In regard to details
for addressing electrical safety, the end use application standard requirements need to be
considered.
This document applies to cells and batteries. If the battery is divided into smaller units, the
smaller unit can be tested as the representative of the battery. The manufacturer clearly
declares the tested unit. The manufacturer can add functions, which are present in the final
battery to the tested unit.
This document addresses first life cells and batteries. Reuse, repurpose, second life use or
similar are not taken into consideration by this document.
Akkumulatoren und Batterien mit alkalischen oder anderen nicht säurehaltigen Elektrolyten - Sicherheitsanforderungen für Lithium-Akkumulatoren und -Batterien für die Verwendung in industriellen Anwendungen
Accumulateurs alcalins et autres accumulateurs à électrolyte non acide - Exigences de sécurité pour les accumulateurs au lithium pour utilisation dans des applications industrielles
IEC 62619:2022 spécifie les exigences et les essais pour le fonctionnement en toute sécurité des accumulateurs au lithium utilisés dans des applications industrielles, y compris les applications stationnaires. Lorsqu'il existe une Norme internationale IEC qui spécifie des conditions d'essai et des exigences pour des éléments destinés à des applications particulières, et qui est en contradiction avec le présent document, la publication particulière est appliquée en priorité (par exemple, la série IEC 62660 sur les véhicules routiers). Ci-après figurent des exemples d’applications qui emploient les éléments et les batteries inclus dans le domaine d’application du présent document :
- applications stationnaires: télécommunications, alimentation sans interruption (ASI), système de stockage d'énergie électrique, sélecteur de service, alimentation de secours et applications similaires;
- applications mobiles: chariot élévateur à fourche, voiturette de golf, véhicule à guidage automatique (AGV, automated guided vehicle), véhicules ferroviaires et marins, à l'exclusion des véhicules routiers.
Sekundarni členi in baterije z alkalnimi ali drugimi nekislinskimi elektroliti - Varnostne zahteve za sekundarne litijeve člene in baterije za industrijsko uporabo
Ta dokument določa zahteve in preskuse za varno uporabo sekundarnih litijevih členov in baterij za industrijsko rabo, vključno s stacionarno uporabo.
Če obstaja mednarodni standard IEC, ki določa preskusne pogoje in zahteve za člene za posebno uporabo ter je v nasprotju s tem dokumentom, ima prednost prvi (npr. skupina standardov IEC 62660 o cestnih vozilih).
V nadaljevanju je navedenih nekaj primerov uporabe členov in baterij v okviru tega dokumenta.
• Stacionarna uporaba: telekomunikacije, napajalniki za neprekinjeno napajanje (UPS), sistem za shranjevanje električne energije, preklapljanje storitev, zasilno napajanje in podobni načini uporabe.
• Pogonska uporaba: viličar, voziček za golf, samodejno vodeno vozilo (AGV), železniška in pomorska vozila, razen cestnih vozil.
Ker ta dokument zajema baterije za različno industrijsko rabo, vključuje skupne in minimalne zahteve za različne načine uporabe.
Električna varnost je vključena samo kot del analize tveganja v točki 8. V povezavi s podrobnostmi za obravnavanje električne varnosti je treba upoštevati standardne zahteve za končno uporabo.
Ta dokument se uporablja za člene in baterije. Če je baterija razdeljena na manjše enote, je mogoče manjšo enoto preskusiti kot reprezentativno za baterijo. Proizvajalec jasno deklarira preskušeno enoto. Proizvajalec lahko preskušeni enoti doda funkcije, ki jih vsebuje končna baterija.
Ta dokument se uporablja za člene in baterije v prvem življenjskem ciklu. Ta dokument ne upošteva vnovične uporabe, spremenjenega namena uporabe, uporabe v drugem življenjskem ciklu in podobnih načinov uporabe.

SAFETY REQUIREMENTS FOR SECONDARY LITHIUM CELLS
AND BATTERIES, FOR USE IN INDUSTRIAL 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.
IEC 62619 has been prepared by subcommittee 21A: Secondary cells and batteries containing
alkaline or other non-acid electrolytes, of IEC technical committee 21: Secondary cells and
batteries. It is an International Standard.
This second edition cancels and replaces the first edition published in 2017. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) new requirements for moving parts;
b) addition of requirements for hazardous live parts;
c) addition of requirements for battery system design;
d) new requirements for system lock;
e) new requirements for EMC;

SAFETY REQUIREMENTS FOR SECONDARY LITHIUM CELLS
AND BATTERIES, FOR USE IN INDUSTRIAL APPLICATIONS
1 Scope
This document specifies requirements and tests for the safe operation of secondary lithium cells
and batteries used in industrial applications, including stationary applications.
When there exists an IEC International Standard specifying test conditions and requirements
for cells used in special applications and which is in conflict with this document, the former
takes precedence (e.g., IEC 62660 series on road vehicles).
The following are some examples of applications that utilize cells and batteries 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: forklift truck, golf cart, automated guided vehicle (AGV), railway
vehicles, and marine vehicles, with the exception of road vehicles.
Since this document covers batteries for various industrial applications, it includes those
requirements which are common and minimum to the various applications.
Electrical safety is included only as a part of the risk analysis of Clause 8. In regard to details
for addressing electrical safety, the end use application standard requirements need to be
