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 62282-4-102 has been prepared by IEC technical committee 105:

Fuel cell technologies.

This second edition cancels and replaces the first edition published in 2017. This edition

constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous

edition:
a) Change the title and scope in accordance with that of IEC 62282-4-101 Ed.2,
b) Deletion of definitions (previous 3.5, 3.10, and 3.15),

c) Add new terms for “3.14 Delivered power” and “3.15 Regenerated power” in clause 3,

d) Revision of symbols and their meanings in accordance with that of IEC 62282-3-201 Ed.2,

e) Replace "reference condition" with "standard condition" as see in clause 5,
f) Revision of the test method for Accessory load voltage spike test (13.3.2),
g) Clarification of 14. Power stability under the operation,
h) Any editorial corrections.

1 INTRODUCTION

2 This part of IEC 62282-4 provides consistent and repeatable test methods for the

3 electric/thermal and environmental performance of fuel cell power systems for electrically

4 powered industrial trucks.
5 The IEC 62282-4 series deals with categories such as safety, performance, and

6 interchangeability of fuel cell power systems for propulsion other than road vehicles and

7 auxiliary power units (APUs). Among the categories mentioned above, this document

8 (IEC 62282-4-102) focuses on fuel cell power systems for electrically powered industrial trucks

9 because such an application is urgently demanded in the world.

10 This part of IEC 62282-4 describes type tests and their test methods only. No routine tests are

11 required or identified, and no performance targets are set in this standard.

12 Fuel cells used in electrically powered industrial trucks, such as forklift trucks, are hybrids and

13 so operate in several different modes. Similarly, forklift trucks operate in different modes. The

14 purpose of this document is to evaluate the fuel cell system in the various combinations of fuel

15 cell modes and forklift truck modes. This document will break down these different modes and

16 provide a framework for designing and evaluating a fuel cell system for use specifically in a

17 forklift truck.

18 This part of IEC 62282-4 is to be used by manufacturers of fuel cell power systems used for

19 electrically powered industrial trucks and/or those who evaluate the performance of their

20 systems for certification purposes.

21 Users of this document selectively execute test items that are suitable for their purposes from

22 those described in this document. This document is not intended to exclude any other methods.
