Overview
IEC 63338:2024 is an international standard published by the International Electrotechnical Commission (IEC) that provides general guidance on the reuse and repurposing of secondary cells and batteries, specifically focusing on secondary lithium-ion and nickel-metal hydride cells and batteries. The standard addresses the environmental and safety considerations involved in reusing batteries after they have been extracted from their initial market application.
This standard includes essential directives for managing and evaluating the suitability of battery reuse, encompassing requirements for battery lifetime traceability data and coordination with the original manufacturers. IEC 63338:2024 aims to support manufacturers, users, and regulators by highlighting the regulatory landscape and safety protocols necessary to enable responsible secondary battery reuse and repurposing.
