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 3.1 0 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. 3.1 1 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
5 General safety considerations 5.1 General Battery systems and the cells they contain shall comply with the applicable general safety considerations of IEC 6261 9. 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. The safety of lithium secondary cells and battery systems requires the consideration of two sets of applied conditions: 1 ) intended use; 2) reasonably foreseeable misuse. Cells and battery systems shall be so designed and constructed that they are safe under conditions of both intended use and reasonably foreseeable misuse.
