IEC 62485-3:2010

Safety requirements for secondary batteries and battery installations - Part 3: Traction batteries

IEC 62485-3:2010 applies to secondary batteries and battery installations used for electric vehicles, e.g. in electric industrial trucks (including lift trucks, tow trucks, cleaning machines, automatic guided vehicles), in battery powered locomotives, in electric vehicles (e.g. goods vehicles, golf carts, bicycles, wheelchairs), and does not cover the design of such vehicles. This International Standard covers lead dioxide-lead (lead-acid), nickel oxide-cadmium, nickel-oxide-metal hydride and other alkaline secondary batteries. Safety aspects of secondary lithium batteries in such applications will be covered in their own appropriate standards. The nominal voltages are limited to 1 000 V AC and 1 500 V DC respectively and describe the principal measures for protection against hazards generally from electricity, gas emission and electrolyte. It provides requirements on safety aspects associated with the installation, use, inspection, maintenance and disposal of batteries.

Exigences de sécurité pour les batteries d'accumulateurs et les installations de batteries - Partie 3: Batteries de traction

La CEI 62485-3:2010 s'applique aux installations d'éléments et de batteries d'accumulateurs utilisées pour les véhicules électriques par exemple dans les chariots électriques industriels (y compris chariots élévateurs, tracteurs, machines de nettoyage, véhicules automatiques guidés), locomotives alimentées par batteries, véhicules électriques routiers (par exemple véhicules pour le transport de marchandises, voiturettes de golf, bicyclettes, chaises roulantes), et ne couvre pas la conception de tels véhicules. Cette norme internationale couvre les accumulateurs au plomb/dioxyde de plomb (plomb acide), oxyde de nickel/cadmium, oxyde de nickel/hydrure métallique et autres accumulateurs alcalins. Les aspects de sécurité des accumulateurs lithium dans ces applications seront couverts par les normes qui leur sont propres. Les tensions nominales sont limitées respectivement à 1 000 V en courant alternatif et 1 500 V en courant continu et donnent les principales mesures de protection contre les risques produits en général par l'électricité, les émissions de gaz et l'électrolyte. Elle fournit les exigences concernant les aspects de sécurité liés à la mise en oeuvre, à l'utilisation, au contrôle, à la maintenance et à la mise au rebut des 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 internation
