IEC 63370: The Most Suitable Approach for Rechargeable Battery System Testing of Battery-Operated Tools

Manufacturers are increasingly adopting IEC 63370 – Rechargeable battery system safety and compatibility requirements for product interchangeability for the testing and certification of rechargeable battery systems, rather than relying on Annex K to IEC 62841. One key reason is the separation of responsibilities in today’s supply chains. In many cases, the tool, battery pack, and charging system are not produced by the same manufacturer, making unified certification under tool-specific standards impractical.

Annex K to IEC 62841 was developed within the context of complete tool systems, assuming that all components are designed and certified together. However, as battery and charger manufacturers often supply to multiple tool brands, there is a growing need for independent certification of battery systems.

IEC 63370 addresses this need by providing a comprehensive standard focused exclusively on the safety and compatibility of rechargeable battery systems, thereby facilitating product interchangeability. It establishes a standalone certification path that evaluates safety, compatibility, charging behaviour, and protection features independently of the end-use tool. This modular approach is particularly well-suited for systems where interoperability between different brands and components is required.

By adopting IEC 63370, battery and charger manufacturers can demonstrate compliance and safety without relying on tool manufacturers. This streamlines product development, increases flexibility, and supports broader market access across multiple platforms. At SIQ we can already support you with the testing according to the IEC 63370 or help you in case you have any additional questions related to this standard.
