12、 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 organizations, governmental

13、 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.The procedures used to develop this document and those intended for its further maintenance are

14、 described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Attention is d

15、rawn 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. Details of any patent rights identified during the development of the document will be in the Introduction and/or o

The requirements for lithium-ion battery systems to be used as power source for the propulsion of electric road vehicl

20、es are significantly different to those batteries used for consumer electronics or for stationary applications.Lithium-ion batteries can store electricity at relatively high-energy density compared to other battery chemistries currently available. Under current state of art, most lithium-ion batteri

21、es use organic electrolytes which are classified as Class 3 “flammable liquid” under the “UN Recommendations on the Transport of Dangerous Goods Model Regulations”. Therefore, mitigating potential hazards associated with fire or explosion of lithium-ion batteries is considered an important issue.Thi

22、s part of ISO 12405 provides specific test procedures and related requirements to ensure an appropriate and acceptable level of safety of lithium-ion battery systems specifically developed for propulsion of road vehicles.

23、ly propelled road vehicles Test specification for lithium-ion traction battery packs and systems Part 3: Safety performance requirements1 ScopeThis part of ISO 12405 specifies test procedures and provides acceptable safety requirements for voltage class B lithium-ion battery packs and systems, to be

24、 used as traction batteries in electrically propelled road vehicles. Traction battery packs and systems used for two-wheel or three-wheel vehicles are not covered by this part of ISO 12405. This part of ISO 12405 is related to the testing of safety performance of battery packs and systems for their

25、intended use in a vehicle. This part of ISO 12405 is not intended to be applied for the evaluation of the safety of battery packs and systems during transport, storage, vehicle production, repair, and maintenance services.2 Normative referencesThe following documents, in whole or in part, are normat
