29、IC VEHICLE BATTERY SWAP SYSTEM Part 2: Safety requirements 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-o
30、peration on all questions 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
31、 as “IEC Publication(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
32、preparation. IEC 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
33、consensus of opinion 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 effo
34、rts are made to ensure 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 Publicati
35、ons transparently 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. Inde
36、pendent certification 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
37、liability shall attach 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 (
38、including legal fees) 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 applicatio
39、n of this publication. 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 62840-2 has been prepared by IEC technica
40、l committee 69: Electric road vehicles and electric industrial trucks. The text of this standard is based on the following documents: FDIS Report on voting 69/420/FDIS 69/433/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the ab
41、ove table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. This standard is to be read in conjunction with IEC 62840-1:2016. IEC 62840-2:2016 IEC 2016 5 in this document, the following print types are used: requirements: in roman type; test specifications: in ita
42、lic type; notes: in small roman type. A list of all parts in the IEC 62840 series, published under the general title Electric vehicle battery swap system, can be found on the IEC website. The following differing practices of a less permanent nature exist in the countries indicated below 7.6.1: RCDs
43、of type AC may be used (Japan). 7.6.1: a device which measures leakage current over a range of frequencies and trips at pre-defined levels of leakage current, based upon the frequency, is required (United States). 10.4: three-part cautionary statements are required (United States). The committee has
44、 decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC website 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 am
45、ended. 6 IEC 62840-2:2016 IEC 2016 INTRODUCTION The purpose of the battery swap system is to provide energy partly or in total to electric vehicles (EV) through fast replacement of their swappable battery systems (SBS). While charging, the EV typically takes a relatively long time, whereas the batte
46、ry swap process takes only a few minutes to complete. Thus it will reduce the range anxiety and will facilitate travel for longer distances. As there is a possibility to charge the batteries after their removal from the vehicle in various ways, the impact of this process on the critical infrastructu
47、re of the electrical grid can be minimized. Battery swap stations mainly include one or more of the following functions: swap of EV swappable battery system (SBS); storage of EV SBS; charging and cooling of EV SBS; testing, maintenance and safety management of EV SBS. This part of IEC 62840 serves a
48、s a generic approach for safety during the lifecycle of battery swap systems and stations for electric vehicles. IEC 62840-2:2016 IEC 2016 7 ELECTRIC VEHICLE BATTERY SWAP SYSTEM Part 2: Safety requirements 1 Scope This part of IEC 62840 provides the safety requirements for a battery swap system, for
49、 the purposes of swapping swappable battery system (SBS) of electric vehicles. The battery swap system is intended to be connected to the supply network. The power supply is up to 1 000 V AC or up to 1 500 V d.c, in accordance with IEC 60038. This standard also applies to battery swap systems supplied from on-site storage systems (e.g. buffer batteries). Aspects covered in this standard: safety requir
