IEC 63370:2022

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).
