IEC 63370:2022

Lithium-ion batteries and charging systems - Safety

IEC 63370:2022 contains a subset of requirements from IEC 62841-1:2014 that are applicable for battery charging systems. The battery charging system includes the battery(ies) and its related charging circuitry. In many cases, the same battery charging system is utilized for a wide variety of end products. Therefore, the purpose of this document is to provide a means for evaluating a battery charging system for electric motor-operated hand-held tools, transportable tools and lawn and garden machinery. This evaluation can then be utilized over a wide range of products covered by IEC 62841 (all parts), without having to re-evaluate the battery charging system for each case where the battery charging system is utilized in or with a product.
This document applies to the safety of lithium-ion batteries and charging systems for use in rechargeable battery-powered motor-operated or magnetically driven
hand-held tools (IEC 62841-2),
transportable tools (IEC 62841-3), and
lawn and garden machinery (IEC 62841-4).

Batteries lithium-ion et systèmes de charge – Sécurité

IEC 63370:2022 Le présent document inclut un sous-ensemble des exigences de l'IEC 62841-1:2014 qui s'appliquent aux systèmes de charge de batteries. Le système de charge de batterie se compose d'une ou de plusieurs batteries, ainsi que de leurs circuits de charge associés. Dans de nombreux cas, le même système de charge de batterie est utilisé pour une vaste gamme de produits finaux. Par conséquent, l'objet du présent document est de fournir un moyen d'évaluer le système de charge de batterie destiné aux outils électroportatifs à moteur, aux outils portables, ainsi qu'aux machines pour jardins et pelouses. Cette évaluation pourra alors être appliquée à une vaste gamme de produits traités par l'IEC 62841 (toutes les parties) sans nécessiter une réévaluation du système de charge de batterie pour chaque cas où celui-ci est utilisé dans ou avec un produit. Le présent document s'applique à la sécurité des batteries lithium-ion et des systèmes de charge associés qui sont destinés à être utilisés dans les produits à entraînement magnétique ou à moteur alimentés par des batteries rechargeables, tels que les:
outils électroportatifs (IEC 62841-2);
outils portables (IEC 62841-3);
machines pour jardins et pelouses (IEC 62841-4).

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.
IEC 63370 has been prepared by IEC technical committee 116: Safety of motor-operated
electric tools. It is an International Standard.
The text of this International Standard is based on the following documents:
Draft Report on voting
116/579/FDIS 116/588/RVD
Full information on the voting for its approval can be found in the report on voting indicated in
the above table.
The language used for the development of this International Standard is English.
This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available
