IEC 63056:2020 pdf download.Secondary cells and batteries containing alkaline or other non-acid electrolytes
1 Scope
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 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.
3 Terms and definitions
For the purposes of this document, the terms and definitions given in IEC 60050-482, ISO/IEC Guide 51, and the following apply. ISO and IEC maintain terminological databases for use in standardization at the following addresses: IEC Electropedia: available at http://www.electropedia.org/ ISO Online browsing platform: available at http://www.iso.org/obp 3.1 safety freedom from unacceptable risk 3.2 risk combination of the probability of occurrence of harm and the severity of that harm 3.3 harm physical injury or damage to the health of people or damage to property or to the environment 3.4 hazard potential source of harm 3.5 intended use use of a product, process or service in accordance with specifications, instructions and information provided by the supplier 3.6 reasonably foreseeable misuse use of a product, process or service in a way which is not intended by the supplier, but which may result from readily predictable human behaviour 3.7 secondary lithium cell cell secondary cell where electrical energy is derived from the insertion/extraction reactions of lithium ions or oxidation/reduction reaction of lithium between the negative electrode and the positive electrode Note 1 to entry: The cell typically has an electrolyte that consists of a lithium salt and organic solvent compound in liquid, gel or solid form and has a metal or a laminate film casing. It is not ready for use in an application because it is not yet fitted with its final housing, terminal arrangement and electronic control device. 3.8 cell block group of cells connected together in parallel configuration with or without protective devices (e.g. fuse or positive temperature coefficient device) and monitoring circuitry Note 1 to entry: It is not ready for use in an application because it is not yet fitted with its final housing, terminal arrangement and electronic control device. 3.9 module group of cells connected together in a series and/or parallel configuration with or without protective devices (e.g. fuse or positive temperature coefficient device) and monitoring circuitry 3.10 battery pack energy storage device which comprises one or more cells or modules electrically connected and has monitoring circuitry which provides information (e.g. cell voltage) to a battery system to influence the battery’s safety, performance and/or service life Note 1 to entry: It may incorporate a protective housing and be provided with terminals or other interconnection arrangement. 3.11 battery system battery system which comprises one or more cells, modules or battery packs and has a battery management system capable of controlling current in case of overcharge, overcurrent, overdischarge, and overheating Note 1 to entry: Overdischarge cut off is not mandatory if there is an agreement between the cell manufacturer and the customer Note 2 to entry: The battery system may have cooling or heating units. More than one battery system may constitute a larger battery system.
