13、ndards bodies (ISO member bodies). The work of preparing International Standards is normally 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 or
14、ganizations, governmental and non-governmental, in liaison with ISO, also take part in the 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 give
15、n in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International 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 7
16、5 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the 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 12405-1 was prepared by Technical Committee ISO/TC 22, R
17、oad vehicles, Subcommittee SC 21, Electrically propelled road vehicles. ISO 12405 consists of the following parts, under the general title Electrically propelled road vehicles Test specification for lithium-ion traction battery systems: Part 1: High-power applications Part 2: High-energy application
18、s BS ISO 12405-1:2011ISO 12405-1:2011(E) ISO 2011 All rights reserved vIntroduction Lithium-ion-based battery systems are an efficient alternative energy storage system for electrically propelled vehicles. The requirements for lithium-ion based battery systems for use as a power source for the propu
19、lsion of electric road vehicles are significantly different from those batteries used for consumer electronics or stationary usage. This part of ISO 12405 provides specific test procedures for lithium-ion battery packs and systems specially developed for propulsion of road vehicles. This part of ISO
20、 12405 specifies such tests and related requirements to ensure that a battery pack or system is able to meet the specific needs of the automobile industry. It enables vehicle manufactures to choose test procedures to evaluate the characteristics of a battery pack or system for their specific require
21、ments. A coordination of test specifications for battery cells, packs and systems for automotive application is necessary for the practical usage of standards. For specifications for battery cells, see IEC 62660-1 and IEC 62660-2. Some tests as prescribed within this specification are based on exist
22、ing specifications, i.e. USABC, EUCAR, FreedomCAR and other sources. BS ISO 12405-1:2011BS ISO 12405-1:2011INTERNATIONAL STANDARD ISO 12405-1:2011(E) ISO 2011 All rights reserved 1Electrically propelled road vehicles Test specification for lithium-ion traction battery packs and systems Part 1: High-
23、power applications 1 Scope This part of ISO 12405 specifies test procedures for lithium-ion battery packs and systems for use in electrically propelled road vehicles. The specified test procedures enable the determination of the essential characteristics of performance, reliability and abuse of lith
24、ium-ion battery packs and systems. They assist the user of this part of ISO 12405 to compare the test results achieved for different battery packs or systems. Therefore, this part of ISO 12405 specifies standard test procedures for basic characteristics of performance, reliability and abuse of lithi
25、um-ion battery packs and systems. This part of ISO 12405 enables the setting up of a dedicated test plan for an individual battery pack or system subject to agreement between the customer and supplier. If required, the relevant test procedures and/or test conditions of lithium-ion battery packs and
26、systems can be selected from the standard tests provided in this part of ISO 12405 to configure a dedicated test plan. This part of ISO 12405 specifies tests for high-power battery packs and systems. NOTE 1 Typical applications for high-power battery packs and systems are hybrid electric vehicles (H
27、EVs) and fuel cell vehicles (FCVs). NOTE 2 Testing on cell level is specified in IEC 62660-1 and IEC 62660-2. 2 Normative references The following referenced documents are indispensable for the application of this document.
