Overview - EN IEC 62660-2:2019 (CLC)
EN IEC 62660-2:2019, published under CLC, is the international European-adopted standard that defines reliability and abuse testing for secondary lithium‑ion cells and cell blocks used to propel electric road vehicles (BEV, HEV, and optionally PHEV). It specifies standardized test procedures, measurement conditions and result classification to obtain essential data on cell behaviour under mechanical, thermal and electrical stress. The standard supports battery system and pack design but does not set pass/fail criteria.
Key topics and technical requirements
The standard addresses test planning, instrumentation and a suite of reliability and abuse tests. Major technical topics include:
Test conditions and measurement
- Specification of measuring instruments and tolerances for voltage, current and temperature.
- Requirements for thermal stabilization and state‑of‑charge (SOC) adjustment before tests.
- Standard capacity and discharge measurement procedures.
Mechanical tests
- Vibration (broadband random vibration, PSD guidance).
- Mechanical shock (specified shock profiles and parameters).
- Crush tests (simulating mechanical intrusion or deformation of cells/cell blocks).
Thermal tests
- High‑temperature endurance to assess long‑term thermal reliability.
- Temperature cycling to evaluate performance under repeated thermal stress.
Electrical abuse tests
- External short‑circuit testing.
- Overcharge testing with revised overcharge conditions.
- Forced discharge procedures (clarified in this edition).
Result description and classification
- Standardized classification for documenting degradation, failure modes and abnormal behaviours to inform battery pack/system design.
Practical applications and users
EN IEC 62660-2:2019 is practical for organizations involved in the development, validation and integration of traction batteries:

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.

INTRODUCTION
The commercialization of electric road vehicles including battery, hybrid and plug-in hybrid
electric vehicles has been accelerated in the global market, responding to the global concerns
on CO reduction and energy security. This, in turn, has led to rapidly increasing demand for
high-power and high-energy-density traction batteries. Lithium-ion batteries are estimated to
be one of the most promising secondary batteries for the propulsion of electric vehicles. In the
light of the rapid spread of hybrid electric vehicles and the emergence of battery and plug-in
hybrid electric vehicles, a standard method for testing reliability and abuse requirements of
lithium-ion batteries is indispensable for securing a basic level of safety and obtaining
essential data for the design of vehicle systems and battery packs.
This document specifies reliability and abuse testing for automobile traction lithium-ion cells
that basically differ from the other cells including those for portable and stationary
applications specified by other IEC standards. For automobile application, it is important to
note the usage specificity; i.e. the design diversity of automobile battery packs and systems,
and specific requirements for cells and batteries corresponding to each of such designs.
Based on these facts, the purpose of this document is to provide a basic test methodology
with general versatility, which serves a function in common primary testing of lithium-ion cells
to be used in a variety of battery systems. This document does not provide any pass-fail
criteria for the tests, but specifies a standard classification of descriptions for test results.
This document is associated with ISO 12405-4 [1] .
IEC 62660-1 [2] specifies the performance testing of lithium-ion cells for electric vehicle
application.
IEC 62660-3 [3] specifies the safety requirements of lithium-ion cells for electric vehicle
application.

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.
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.

INTRODUCTION
The commercialization of electric road vehicles including battery, hybrid and plug-in hybrid
electric vehicles has been accelerated in the global market, responding to the global concerns
on CO reduction and energy security. This, in turn, has led to rapidly increasing demand for
high-power and high-energy-density traction batteries. Lithium-ion batteries are estimated to
be one of the most promising secondary batteries for the propulsion of electric vehicles. In the
light of the rapid spread of hybrid electric vehicles and the emergence of battery and plug-in
hybrid electric vehicles, a standard method for testing reliability and abuse requirements of
lithium-ion batteries is indispensable for securing a basic level of safety and obtaining
essential data for the design of vehicle systems and battery packs.
This document specifies reliability and abuse testing for automobile traction lithium-ion cells
that basically differ from the other cells including those for portable and stationary
applications specified by other IEC standards. For automobile application, it is important to
note the usage specificity; i.e. the design diversity of automobile battery packs and systems,
and specific requirements for cells and batteries corresponding to each of such designs.
Based on these facts, the purpose of this document is to provide a basic test methodology
with general versatility, which serves a function in common primary testing of lithium-ion cells
to be used in a variety of battery systems. This document does not provide any pass-fail
criteria for the tests, but specifies a standard classification of descriptions for test results.
This document is associated with ISO 12405-4 [1] .
IEC 62660-1 [2] specifies the performance testing of lithium-ion cells for electric vehicle
application.
IEC 62660-3 [3] specifies the safety requirements of lithium-ion cells for electric vehicle
application.
