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


Do you need a multi-user copy?




IEC 63056:2020 specifies requirements and tests for the product safety of secondary lithium cells and batteries used in electrical energy storage systems (Figure 2) 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:
• telecommunications,
• central emergency lighting and alarm systems,
• stationary engine starting,
• photovoltaic systems,
• home (residential) energy storage systems (HESS), and
• large energy storage: on-grid/off-grid.
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.
The contents of the corrigendum of June 2021 have been included in this copy.
