Secondary cells and batteries containing alkaline or other non-acid electrolytes - Safety requirements for secondary lithium cells and batteries, for use in industrial applications

IEC 62619:2017 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 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, auto guided vehicle (AGV), railway, and marine, excluding 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 have 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 may add functions, which are present in the final battery to the tested unit.

Accumulateurs alcalins et autres accumulateurs à électrolyte non acide - Exigences de sécurité pour les accumulateurs au lithium pour utilisation dans des applications industrielles

L'IEC 62619:2017 spécifie les exigences et les essais pour le fonctionnement en toute sécurité des éléments et des batteries d’accumulateurs au lithium utilisés dans des applications industrielles, y compris les applications stationnaires.
En cas d'existence d'une norme IEC spécifiant des conditions d'essai et des exigences pour des éléments destinés à des applications particulières, et qui serait 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 utilisant 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), ferroviaire et marine, à l'exclusion des véhicules routiers.
Étant donné que le présent document couvre les batteries destinées à différentes applications industrielles, il inclut ces exigences qui sont communes et minimales pour les différentes applications.
La sécurité électrique est incluse uniquement dans le cadre de l'analyse des risques de l'Article 8. Concernant les détails en matière de sécurité électrique, les exigences normalisées relatives à l'application finale sont à prendre en compte.
Le présent document s'applique aux éléments et aux batteries. Si la batterie est divisée en unités plus petites, l’unité plus petite peut être soumise à essai pour représenter la batterie. Le fabricant déclare clairement l'unité soumise à essai. Il peut ajouter des fonctions, qui sont présentes dans la batterie finale, à l'unité soumise à essai.

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.

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 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, auto guided vehicle (AGV), railway, and marine,

excluding 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 have 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 may add functions, which are present in the final

battery to the tested unit.
2 Normative references

5 General safety considerations
5.1 General

The safety of lithium secondary cells and batteries requires the consideration of two sets of

applied conditions:
a) intended use;
b) reasonably foreseeable misuse.

Cells and batteries shall be so designed and constructed that they are safe under conditions

of both intended use and reasonably foreseeable misuse. It may also be expected that cells

and batteries subjected to intended use shall not only be safe but shall continue to be

functional in all respects.

It is expected that cells or batteries subjected to misuse may fail to function. However, even if

such a situation occurs, they shall not present any significant hazards.
Potential hazards which are the subject of this document are:
a) fire,
b) burst/explosion,
c) critical electrical short-circuit due to leakage of cell electrolyte,
d) venting which continuously vents out flammable gases,

e) rupture of the casing of cell, module, battery pack, and battery system with exposure of

internal components.

Conformity with 5.1 to 5.6 is checked by the tests of Clauses 6, 7, and 8, and in accorda
