IEC 63057:2020 pdf download.Secondary cells and batteries containing alkaline or other non-acid electrolytes
1 Scope
This document specifies safety tests and requirements for secondary lithium batteries permanently installed in road vehicles not for the propulsion. Replacement secondary batteries permanently installed in road vehicles not for propulsion are covered by this document. The following are typical applications that utilize the batteries under the scope of this document: a power source for the starting of internal combustion engines, lighting, on-board auxiliary equipment, and energy absorption for regeneration from braking. This document applies to batteries with a maximum voltage less than or equal to 60 V DC. The batteries primarily used for propulsion of electric vehicles (EVs), including battery electric vehicles (BEVs), hybrid electric vehicles (HEVs), and plug-in hybrid electric vehicles (PHEVs) are not covered by this document. NOTE Testing on cell level is specified in IEC 6261 9.

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.3.1 battery unit comprising one or more cells, modules and a battery management system 3.2 battery management system BMS set of protection functions associated with a battery to prevent overcharge, overcurrent, over temperature, under temperature and if applicable overdischarge Note 1 to entry: The function of the BMS can be assigned to the battery or to the vehicle that uses the battery. See Figure 1 . Note 2 to entry: The BMS can be divided and it can be found partially in the battery and partially on the equipment that uses the battery. See Figure 1 . Note 3 to entry: The BMS is sometimes also referred to as a BMU (battery management unit). Note 4 to entry: This term applies to the French language only. 3.3 cell secondary cell where electrical energy is derived from the insertion or 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. 3.4 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. 3.5 explosion failure that occurs when a battery case opens violently, and solid components are forcibly expelled Note 1 to entry: Liquid, gas, and smoke can be erupted. 3.6 final voltage specified closed circuit voltage at which the discharge of a battery is terminated Note 1 to entry: The final voltage should be declared by the battery manufacturer.
