Secondary lithium-ion cells for the propulsion of electric road vehicles - Part 3: Safety requirements

IEC 62660-3:2016 specifies test procedures and the acceptance criteria for safety performance of secondary lithium-ion cells and cell blocks used for the propulsion of electric vehicles (EV) including battery electric vehicles (BEV) and hybrid electric vehicles (HEV). This International Standard intends to determine the basic safety performance of cells used in a battery pack and system under intended use, and reasonably foreseeable misuse or incident, during the normal operation of the EV. The safety requirements of the cell in this standard are based on the premise that the cells are properly used in a battery pack and system within the limits for voltage, current and temperature as specified by the cell manufacturer (cell operating region). The evaluation of the safety of cells during transport and storage is not covered by this standard.

Lithium-Ionen-Sekundärzellen für den Antrieb von Elektrostraßenfahrzeugen - Teil 3: Sicherheitsanforderungen

Éléments d’accumulateurs lithium-ion pour la propulsion des véhicules routiers électriques - Partie 3: Exigences de sécurité

L'IEC 62660-3:2016 spécifie les procédures d'essai et les critères d'acceptation en matière de performance de sécurité des éléments d'accumulateurs lithium-ion et des blocs d'éléments utilisés pour la propulsion des véhicules électriques (EV), y compris les véhicules électriques à batterie (BEV) et les véhicules électriques hybrides (HEV). La présente Norme internationale a pour objet de déterminer les performances de sécurité de base des éléments utilisés dans un bloc et système de batteries dans les conditions d'utilisation prévue et les utilisations abusives ou incidents raisonnablement prévisibles, pendant le fonctionnement normal de l'EV. Dans la présente norme, les exigences de sécurité de l'élément s'appuient sur l'hypothèse selon laquelle les éléments sont correctement utilisés dans un bloc et système de batteries dans les limites de tension, de courant et de température spécifiées par le fabricant de l'élément (plage de fonctionnement de l'élément). L'évaluation de la sécurité des éléments pendant le transport et le stockage n'est pas couverte par la présente norme.

Sekundarni litij-ionski členi za pogon električnih cestnih vozil - 3. del: Varnostne zahteve

Ta del standarda IEC 62660 določa preskusne postopke in merila sprejemljivosti za varnostne lastnosti sekundarnih litij-ionskih členov in blokov členov, ki se uporabljajo za pogon električnih vozil (EV), vključno z električnimi akumulatorskimi vozili (BEV) ali hibridnimi električnimi vozili (HEV).
OPOMBA 1: Kot alternativa členom se lahko v skladu z dogovorom med proizvajalcem in kupcem uporabijo bloki členov.
OPOMBA 2: V povezavi s členom za hibridna cestna vozila z možnostjo polnjenja prek navadne vtičnice (PHEV) lahko proizvajalec izbere preskuse pogoje za uporabo električnih akumulatorskih vozil ali hibridnih električnih vozil.
Ta mednarodni standard je namenjen za določanje osnovnih varnostnih lastnosti členov v akumulatorju in sistemu v skladu s predvideno uporabo ter pričakovano nepravilno uporabo ali incident pri običajnem delovanju električnih vozil. Varnostne zahteve za člen v tem standardu temeljijo na predpostavki, da se členi pravilno uporabljajo v akumulatorju ter sistemu znotraj napetostnih, tokovnih in temperaturnih omejitev, ki jih določi proizvajalec členov (območje delovanja členov).
Ta standard ne vključuje ocene varnosti za člene med prevozom in skladiščenjem.
OPOMBA 3: Varnostne zahteve glede zmogljivosti litij-ionskih akumulatorjev in sistemov so opredeljene v standardu ISO 12405-3. Specifikacije in varnostne zahteve za litij-ionske akumulatorje ter sisteme električno gnanih mopedov in motornih koles so opredeljena v standardu ISO 18243 (v pripravi). IEC 62619 (v pripravi) zajema varnostne zahteve za litij-ionske člene in akumulatorje za industrijsko uporabo, vključno z viličarji, vozički za golf in avtomatsko vodenimi vozili.
OPOMBA 4: Informacije o območju delovanja členov so podane v dodatku A.

SECONDARY LITHIUM-ION CELLS FOR THE PROPULSION

Part 3: Safety requirements
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 th
