Secondary lithium-ion cells for the propulsion of electric road vehicles - Part 1: Performance testing
IEC 62660-1:2018 specifies performance and life testing of secondary lithium-ion cells used for propulsion of electric vehicles including battery electric vehicles (BEV) and hybrid electric vehicles (HEV). This document specifies the test procedures to obtain the essential characteristics of lithium-ion cells for vehicle propulsion applications regarding capacity, power density, energy density, storage life and cycle life. This document provides the standard test procedures and conditions for testing basic performance characteristics of lithium-ion cells for vehicle propulsion applications, which are indispensable for securing a basic level of performance and obtaining essential data on cells for various designs of battery systems and battery packs. IEC 62660-1:2018 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 purpose of each test has been added.
b) The power test has been revised for clarification, and an informative part of the current-voltage characteristic test has been moved to the new Annex C.

L'IEC 62660-1:2018 spécifie les essais de performance et de durée de vie des accumulateurs lithium-ion utilisés pour la propulsion des véhicules électriques, incluant les véhicules électriques à batterie (BEV) et les véhicules électriques hybrides (HEV). Le présent document spécifie les procédures d'essai afin d’obtenir les caractéristiques essentielles des éléments lithium-ion destinés aux applications de propulsion de véhicules; ces caractéristiques concernent la capacité, la densité de puissance, la densité d'énergie, la durée de stockage et la durée de vie. Le présent document spécifie les procédures d'essai et les conditions normalisées pour effectuer les essais des caractéristiques de performance fondamentales des éléments lithium-ion destinés aux applications de propulsion de véhicules; ces caractéristiques sont indispensables pour fixer un niveau de performance de base et obtenir des données essentielles pour différentes conceptions de systèmes de batteries et de packs de batteries. L'IEC 62660-1:2018 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) L’objet de chaque essai a été ajouté.
b) L’essai de puissance a été révisé pour clarification, et une partie informative de l’essai des caractéristiques courant-tension a été transférée à la nouvelle Annexe C.

Part 1: Performance 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
