Secondary lithium-ion cells for the propulsion of electric road vehicles - Part 2: Reliability and abuse testing
IEC 62660-2:2018 specifies test procedures to observe the reliability and abuse behaviour of secondary lithium-ion cells and cell blocks used for propulsion of electric vehicles including battery electric vehicles (BEV) and hybrid electric vehicles (HEV). This document specifies the standard test procedures and conditions for basic characteristics of lithium-ion cells for use in propulsion of battery and hybrid electric vehicles. The tests are indispensable for obtaining essential data on reliability and abuse behaviour of lithium-ion cells for use in various designs of battery systems and battery packs. This document provides standard classification of description of test results to be used for the design of battery systems or battery packs. IEC 62660-2:2018 cancels and replaces the first edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) The procedure of forced discharge test has been clarified (6.4.3.2).
b) "Cell block" has been added to the scope (Clause 1).
c) Option of temperature cycling test with electrical operation has been deleted (6.3.2).
d) The test conditions for overcharge test have been revised (6.4.2.2).
Eléments d'accumulateurs lithium-ion pour la propulsion des véhicules routiers électriques - Partie 2: Essais de fiabilité et de traitement abusif
L'IEC 62660-2:2018 spécifie les procédures d'essai destinées à observer la fiabilité et le comportement sous traitement abusif des éléments et des blocs d’éléments d’accumulateurs lithium-ion utilisés pour la propulsion des véhicules électriques, y compris les véhicules électriques à batterie (BEV) et les véhicules électriques hybrides (HEV). Le présent document spécifie les procédures et les conditions d'essai normalisées pour des caractéristiques fondamentales des éléments lithium-ion utilisés pour la propulsion des véhicules électriques à batterie d’accumulateurs et hybrides. Les essais sont indispensables pour obtenir des données importantes sur la fiabilité et sur le comportement sous traitement abusif des éléments lithium-ion utilisés dans différentes conceptions de systèmes de batteries et de packs de batteries. Le présent document donne une classification normalisée de la description des résultats d'essai à utiliser pour la conception des systèmes de batteries et des packs de batteries. L'IEC 62660-2:2018 annule et remplace la première édition parue en 2010. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) La procédure d'essai de décharge forcée a été clarifiée (6.4.3.2).
b) Le concept de "bloc d’éléments" a été ajouté au domaine d’application (Article 1).
c) L’option d’essai de cycles de température avec fonctionnement électrique a été supprimée (6.3.2).

SECONDARY LITHIUM-ION CELLS FOR
THE PROPULSION OF ELECTRIC ROAD VEHICLES –
Part 2: Reliability and abuse testing
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 redline version of the official IEC Standard allows the user to identify the changes
made to the previous edition. A vertical bar appears in the margin wherever a change
has been made. Additions are in green text, deletions are in strikethrough red text.
International Standard IEC 62660-2 has been prepared by IEC technical committee 21:
Secondary cells and batteries.
This second edition cancels and replaces the first edition published in 2010. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) The procedure of forced discharge test has been clarified (6.4.3.2).
b) "Cell block" has been added to the scope (Clause 1).
c) Option of temperature cycling test with electrical operation has been deleted (6.3.2).
d) The test conditions for overcharge test have been revised (6.4.2.2).
The text of this International Standard is based on the following documents:
FDIS Report on voting
21/976/FDIS 21/986/RVD
