29、DRIDE PRISMATIC RECHARGEABLE SINGLE CELLS FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all q
30、uestions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publicat
31、ion(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC
32、collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opin
33、ion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to e
34、nsure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently
35、 to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certifica
36、tion bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall a
37、ttach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal f
38、ees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publica
39、tion. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 62675 has been prepared by subcommittee 21A: Secondary cel
40、ls and batteries containing alkaline or other non-acid electrolytes, of IEC technical committee 21: Secondary cells and batteries. The text of this standard is based on the following documents: FDIS Report on voting 21A/550/FDIS 21A/560/RVD Full information on the voting for the approval of this sta
41、ndard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. IEC 62675:2014 IEC 2014 5 The committee has decided that the contents of this publication will remain unchanged until the stability date indic
42、ated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 6 IEC 62675:2014 IEC 2014 SECONDARY CELLS AND BATTERIES CONTAINING ALKALINE OR OTHER NON-AC
43、ID ELECTROLYTES SEALED NICKEL-METAL HYDRIDE PRISMATIC RECHARGEABLE SINGLE CELLS 1 Scope This International Standard specifies marking, designation, dimensions, tests and requirements for sealed nickel-metal hydride prismatic secondary single cells. NOTE In this context, “prismatic“ refers to cells h
44、aving rectangular sides and base. When there exists an IEC standard specifying test conditions and requirements for cells used in special applications and which is in conflict with this standard, the former takes precedence. 2 Normative references The following documents, in whole or in part, are no
45、rmatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 60050-482:2004, International Electrotechnical Vocabula
46、ry (IEV) Part 482: Primary and secondary cells and batteries 3 Terms and definitions For the purposes of this document, the terms and definitions given in the IEC 60050-482, as well as the following apply. 3.1 sealed cell cell which remains closed and does not release either gas or liquid when opera
47、ted within the limits of charge and temperature specified by the manufacturer Note 1 to entry: The cell is equipped with a safety device to prevent dangerously high internal pressure. Note 2 to entry: The cell does not require addition to the electrolyte and is designed to operate during its life in
48、 its original sealed state. Note 3 to entry: The nickel-metal hydride cell, however, may release gas towards the end of its life due to the accumulation of hydrogen in the cell. SOURCE: IEC 60050-482:2004, 482-05-17, modified The existing note has been developed into Notes 1, 2 and 3 to entry. 3.2 n
49、ominal voltage suitable approximate value of voltage used to designate or identify the voltage of a cell or battery Note 1 to entry: The nominal voltage of a sealed nickel-metal hydride rechargeable single cell: 1,2 V. Note 2 to entry: The nominal voltage of a battery of n series connected cells is equal to n times the nominal voltage of a single cell. IEC 62675:2014 IEC 2014 7 SO
