EN IEC 62281 pdf download.SAFETY OF PRIMARY AND SECONDARY LITHIUM CELLS AND BATTERIES DURING TRANSPORT
1 Scope
This International Standard specifies test methods and requirements for primary and secondary (rechargeable) lithium cells and batteries to ensure their safety during transport other than for recycling or disposal. Requirements specified in this document do not apply in those cases where special provisions given in the relevant regulations, listed in 7.3, provide exemptions. NOTE Different standards may apply for lithium-ion traction battery systems used for electrically propelled road vehicles.
3 Terms and definitions
For the purposes of this document, the following terms and definitions 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 aggregate lithium content total lithium content of the cells comprising a battery 3.2 battery one or more cells electrically connected and fitted in a case, with terminals, markings and protective devices etc., as necessary for use Note 1 to entry: This definition is different from the definition used in the UN Manual of Tests and Criteria [1 2]. This document was, however, carefully prepared so that the test set-up for each test is harmonized with the UN Manual. Note 2 to entry: A cell used in equipment where the equipment is providing the functions of a case, terminals, markings and protective devices etc., as necessary for use in the equipment, is, for the purposes of this document, considered to be a battery. [SOURCE: IEC 60050-482:2004 [1 ], 482-01 -04, modified – Reference to “electrically connected” has been added.] 3.3 battery assembly battery comprising two or more batteries 3.4 coin cell or battery lithium button cell or battery small round cell or battery where the overall height is less than the diameter, containing non- aqueous electrolyte Note 1 to entry: The nominal voltage of lithium batteries is typically greater than 2 V. [SOURCE: IEC 60050-482:2004, 482-02-40, modified – The definition “small round cell or battery” replaces the original “cell with a cylindrical shape”, “containing non-aqueous electrolyte” was added, the term “lithium button” was added] 3.5 cell basic functional unit, consisting of an assembly of electrodes, electrolyte, container, terminals and, usually, separators that is a source of electric energy obtained by direct conversion of chemical energy [SOURCE: IEC 60050-482:2004, 482-01 -01 ] 3.6 component cell cell contained in a battery 3.7 cycle <of a secondary (rechargeable) cell or battery> set of operations that is carried out on a secondary (rechargeable) cell or battery and is repeated regularly in the same sequence Note 1 to entry: These operations may consist of a sequence of a discharge followed by a charge or a charge followed by a discharge under specified conditions. This sequence may include rest periods. [SOURCE: IEC 60050-482:2004, 482-05-28, modified – The words “secondary (rechargeable)” have been added.] 3.8 cylindrical cell or battery round cell or battery in which the overall height is equal to or greater than the diameter [SOURCE: IEC 60050-482:2004, 482-02-39, modified – The words “round cell or battery” replace the original “cell with a cylindrical shape”, the term “cylindrical battery” has been added.] 3.9 depth of discharge DOD percentage of rated capacity discharged from a battery Note 1 to entry: This note applies to the French language only. 3.1 0 first cycle initial cycle of a secondary (rechargeable) cell or battery following completion of all manufacturing, formation and quality control processes 3.1 2 fully discharged, adj state of charge of a cell or battery corresponding to 1 00 % depth of discharge 3.1 3 large battery battery with a gross mass of more than 1 2 kg 3.1 4 large cell cell with a gross mass of more than 500 g 3.1 5 lithium cell <primary or secondary (rechargeable)> cell containing a non-aqueous electrolyte and a negative electrode of lithium or containing lithium Note 1 to entry: Depending on the design features chosen, a lithium cell may be primary or secondary (rechargeable). [SOURCE: IEC 60050-482:2004, 482-01 -06, modified – The domain “primary or secondary (rechargeable)” has been added.] 3.1 6 lithium content mass of lithium in the negative electrode of a lithium metal or lithium alloy cell or battery in the undischarged or fully charged state 3.1 7 lithium ion cell or battery rechargeable non-aqueous cell or battery in which the positive and negative electrodes are both intercalation compounds constructed with no metallic lithium in either electrode Note 1 to entry: Intercalated lithium exists in an ionic or quasi-atomic form with the lattice of the electrode material. Note 2 to entry: A lithium polymer cell or battery that uses lithium ion chemistries, as described herein, is considered as a lithium ion cell or battery.
