6、de federation of national standards 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 tha
7、t committee. International organizations, 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 a
8、ccordance with the rules given 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 re
9、quires approval by at least 75 % of the member bodies casting a vote. In other circumstances, particularly when there is an urgent market requirement for such documents, a technical committee may decide to publish other types of document: an ISO/IEC Publicly Available Specification (ISO/IEC PAS) rep
10、resents an agreement between technical experts in an ISO working group and is accepted for publication if it is approved by more than 50 % of the members of the parent committee casting a vote; an ISO/IEC Technical Specification (ISO/IEC TS) represents an agreement between the members of a technical
11、 committee and is accepted for publication if it is approved by 2/3 of the members of the committee casting a vote. An ISO/IEC PAS or ISO/IEC TS is reviewed after three years in order to decide whether it will be confirmed for a further three years, revised to become an International Standard, or wi
12、thdrawn. If the ISO/IEC PAS or ISO/IEC TS is confirmed, it is reviewed again after a further three years, at which time it must either be transformed into an International Standard or be withdrawn. Attention is drawn to the possibility that some of the elements of this document may be the subject of
13、 patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO/IEC PAS 16898 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 21, Electrically propelled road vehicles.iv ISO/IEC 2012 All rights reserved ISO/IEC PAS 16898:2012(E) Intr
14、oduction The vehicle traction battery system as a large and very costly component of an electrically propelled vehicle has a huge influence on the vehicle design. Depending on vehicle dimensions and package constraints, the shape of battery packs and systems has to follow a top-down procedure. The d
15、imensional requirements on lithium-ion cells for automotive application are given by the battery system, which is influenced by the vehicle design. Therefore, this Publicly Available Specification (PAS) was developed in a joint ISO and IEC Working Group consisting of experts from the automotive indu
16、stry, the automotive suppliers, the battery and the cell industry. Today there is a huge variety of different cell types and dimensions on the market. When a traction battery system design is finished based on one specific cell, a change to another cell or cell supplier is quite difficult or may not
17、 be possible. It is necessary to reduce this variety in order to: lower the cell costs through encouraging competition and allowing cell suppliers access to the worldwide market, enable an exchange of the cells from different suppliers during and after the battery system development, and support the
18、 battery system design by specifying basic outer dimensions per known design type of lithium-ion cells for automotive traction battery systems. By specifying only a certain number of cell dimensions for vehicle propulsion, this PAS aims to reduce the number of different dimensions. It should further
19、more ensure that cells of the dimensions as listed in this PAS will be used in the long term by the vehicle manufacturers for their current and future models. Cells of these dimensions need to be available for the vehicle production time, plus the vehicle life time, plus the legally required spare p
20、art availability time. This PAS lists only those battery cells, chosen from the currently existing variety, which will be used for the current and planned vehicle models and which are currently available. This PAS does not exclude the usage of other cell dimensions in vehicle models. This PAS is not
21、 intended to restrict the development of cell technology. Therefore no requirements are specified in this PAS for the cell chemistry, the usage of materials or any electrical characteristics.

22、ary lithium-ion cells 1 Scope This Publicly Available Specification (PAS) specifies a designation system as well as the shapes and dimensions for secondary lithium-ion cells for integration into battery packs and systems used in electrically propelled road vehicles including the position of the term
23、inals and any over-pressure safety device (OPSD). It is related to cylindrical, prismatic and pouch cells. The cell designation according to this PAS is intended to be applied to the cells used for electrically propelled road vehicles. This PAS does not apply to cells specifically used for mopeds, m
24、otorcycles and vehicles not primarily defined as road vehicles, i.e. material handling trucks or forklifts. The cell dimensions listed in this PAS are recommended but not restricted for use in passenger cars up to 3,5 t. The inner design, the cell chemistry, the electrical characteristics and any fu
25、rther properties of the cells are not defined in this PAS. 2 Normative references The following referenced documents are indispensable for the application of this document.
