Summary: According to the official IEC website, IEC 63056:2020 "Secondary cells and batteries containing alkaline or other non-acid electrolytes-Safety requirements for secondary lithium cells and batteries for use in electrical energy storage systems" was officially released on March 27, 2020. IEC 63056:2020 is under the jurisdiction of IEC/SC21A, under which the WG5 working group is responsible for the formulation.
Since IEC 63056:2020 covers batteries for various electrical energy storage systems, the standard only specifies common and minimum requirements.
(Safety requirements for secondary lithium batteries and accumulators containing alkaline or other non-acid electrolytes used in electrical energy storage systems)
IEC 63056:2020 specifies requirements and tests for the product safety of secondary lithium cells and batteries used in electrical energy storage systems with a maximum DC voltage of 1,500 V (nominal).
Basic safety requirements for the secondary lithium cells and batteries used in industrial applications are included in IEC 62619. This document provides additional or specific requirements for electrical energy storage systems.
Since this document covers batteries for various electrical energy storage systems, it includes those requirements which are common and minimum to the electrical energy storage systems.
Examples of appliances that are within the scope of this document are:
This document applies to cells and batteries for uninterruptible power supplies (UPS).
This document does not apply to portable systems 500 Wh or below, which are covered by IEC 61960-3.
