Sekundarni litij-ionski členi za pogon električnih cestnih vozil - 2. del: Preskušanje zanesljivosti in izrabljivosti

Ta del IEC 62660 določa preskusne postopke za opazovanje zanesljivosti in izrabljivosti sekundarnih litij-ionskih členov, ki se uporabljajo za pogon električnih vozil, vključno z baterijskimi električnimi vozili (BEV) in hibridnimi električnimi vozili (HEV). Namen tega standarda je določiti standardne preskusne postopke in pogoje za osnovne značilnosti litij-ionskih členov za uporabo pri pogonu baterijskih in hibridnih električnih vozil. Preskusi so nepogrešljivi za pridobivanje bistvenih podatkov o zanesljivosti in izrabljivosti litij-ionskih členov za uporabi pri različnih zasnovah baterijskih sistemov in kompletov baterij. Ta standard podaja standardno klasifikacijo opisa rezultatov preskušanj, ki se uporabljajo pri načrtovanju baterijskih sistemov ali kompletov baterij.

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 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 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 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

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 efforts 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 Publications

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. Independent 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 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 (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 application 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 62660-2 has been prepared by IEC technical committee 21:

Secondary cells and batteries.
The text of this standard is based on the following documents:

INTRODUCTION

The commercialisation of electric road vehicles including battery, hybrid and plug-in hybrid

electric vehicles has been accelerated in the global market, responding to the global concerns

on CO reduction and energy security. This, in turn, has led to rapidly increasing demand for

high-power and high-energy density traction batteries. Lithium-ion batteries are estimated to

be one of the most promising secondary batteries for the propulsion of electric vehicles. In the

light of rapidly diffusing hybrid electric vehicles and emerging battery and plug-in hybrid

electric vehicles, a standard method for testing reliability and abuse requirements of lithium-

ion batteries is indispensable for securing a basic level of safety and obtaining essential data

for the design of vehicle systems and battery packs.

This standard is to specify reliability and abuse testing for automobile traction lithium-ion cells

that basically differ from the other cells including those for portable and stationary

applications specified by the other IEC standards. For automobile application, it is important

to note the usage specificity; i.e. the designing diversity of automobile battery packs and

systems, and specific requirements for cells and batteries corresponding to each of such

designs. Based on these facts, the purpose of this standard is to provide a basic test

methodology with general versatility, which serves a function in common primary testing of

lithium ion cells to be used in a variety of battery systems. For the requirements for cells differ

depending on the system designs of battery pack or vehicle, and should be evaluated by the

users, this standard does not provide any pass-fail criteria for the tests, but specifies a

standard classification of descriptions for test results.
This standard is associated with ISO 12405-1-and ISO 12405-2 .

IEC 62660-1 specifies the performance testing of lithium-ion cells for electric vehicle

application.
