BS EN IEC 63056:2020 pdf free.Secondary cells and batteries containing alkaline or other non-acid electrolytes一Safety requirements for secondary lithium cells and batteries for use in electrical energy storage systems.
BS EN IEC 63056 This document 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 hose 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.Battery systems and the cells they contain shall comply with the applicable general safety considerations of IEC 62619. Within the standard temperature range, secondary cells can be charged at the maximum charge current, which is specified from a safety point of view. Lithium-ion cells shall always be operated within the operating region values and the storage conditions specified by the manufacturer.Wiring and its insulation shall be sufficient to withstand the maximum anticipated voltage, current, temperature, altitude and humidity requirements. The design of wiring shall be such  that adequate clearances and creepage distances are maintained between conductors in accordance with IEC 60950-1:2005，3.1 and 3.2 (test temperature relies on the battery system’s operating region specified by the manufacturer). Hazardous live parts of the battery system shall be protected to avoid the risk of electric shocks, including during installation. BS EN IEC 63056 pdf download.
