The work of preparing International Standards is normall

13、y carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the

14、work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare Inte

15、rnational Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.Attention is drawn to the possibility that some of th

16、e elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.ISO 12405-2 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 21, Electrically propelled road vehicles.ISO 12405 consists of th

The requirements for lithium-ion based battery systems to be used as a power source for the propulsion

19、 of electric road vehicles are significantly different from those for batteries used for consumer electronics or stationary usage.ISO 12405 provides specific test procedures for lithium-ion battery packs and systems specially developed for propulsion of road vehicles. It specifies such tests and rel

20、ated requirements to ensure that a battery pack or system is able to meet the specific needs of the automobile industry. It enables vehicle manufacturers to choose test procedures to evaluate the characteristics of a battery pack or system for their specific requirements.A coordination of test speci

21、fications for battery cells, packs and systems for automotive application is necessary for practical usage of standards.Specifications for battery cells are given in IEC 62660-1 and IEC 62660-2.Some tests as prescribed within this specification are based on existing specifications: USABC, EUCAR, Fre

23、 packs and systems to be used in electrically propelled road vehicles.The specified test procedures enable the user of ISO 12405 to determine the essential characteristics of performance, reliability and abuse of lithium-ion battery packs and systems. They also assist the user in comparing the test

24、results achieved for different battery packs or systems.Therefore the objective of ISO 12405 is to specify standard test procedures for the basic characteristics of performance, reliability and abuse of lithium-ion battery packs and systems.ISO 12405 enables the setting up of a dedicated test plan f

25、or an individual battery pack or system subject to an agreement between customer and supplier. If required, the relevant test procedures and/or test conditions of lithium-ion battery packs and systems can be selected from the standard tests provided in ISO 12405 to configure a dedicated test plan.Th
