Electric vehicle wireless power transfer (wpt) systems - Part 3: Specific requirements for the magnetic field wireless power transfer systems

This part of IEC 61980 series, (in a first step as Technical Specification for three-year period) applies to the equipment for the magnetic field-wireless power transfer (MF-WPT) of electric power from the supply network to electric road vehicles for purposes of supplying electric energy to the RESS (Rechargeable energy storage system) and/or other on-board electrical systems in an operational state when connected to the supply network, at standard supply voltages ratings per IEC 60038 up to 1000V a.c. and up to 1500 V d.c.This standard also applies to MF-WPT equipment supplied from on-site storage systems (e.g. buffer batteries etc.) at standard supply voltages ratings per IEC 60038 up to 1000V a.c. and up to 1500 V d.c.

Part 3: Specific requirements for the magnetic field wireless power

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.

The main task of IEC technical committees is to prepare International Standards. In

exceptional circumstances, a technical committee may propose the publication of a technical

specification when

• the required support cannot be obtained for the publication of an International Standard,

despite repeated efforts, or

• the subject is still under technical development or where, for any other reason, there is the

future but no immediate possibility of an agreement on an International Standard.

Technical specifications are subject to review within three years of publication to decide

whether they can be transformed into International Standards.

IEC TS 61980-3, which is a Technical Specification, has been prepared by IEC technical

committee 69: Electric road vehicles and electric industrial trucks.

This part is to be used in conjunction with IEC 61980-1:2015.

The clauses of the particular requirements in this document supplement or modify the

corresponding clauses in IEC 61980-1:2015. Where the text indicates an "addition" to or a

"replacement" of the relevant requirement, test specification or explanation of

IEC 61980-1:2015, these changes are made to the relevant text of IEC 61980-1:2015, which

then becomes part of the standard. Where no change is necessary, the words "Clause xx of

IEC 61980-1:2015 is applicable" are used. Additional items to those of IEC 61980-1:2015 are

numbered starting 101. Additional annexes are lettered from AA onwards.

The committee has decided that the contents of this document will remain unchanged until the

stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to

INTRODUCTION

The IEC 61980 series is published in separate parts according to the following structure:

– IEC 61980-1 covers general requirements for electric road vehicle (EV) wireless power

transfer (WPT) systems including general background and definitions. (e.g. efficiency,

electrical safety, EMC);

– IEC TS 61980-2 covers specific requirements for communication between electric road

vehicle (EV) and wireless power transfer (WPT) systems including general background

and definitions.

– IEC TS 61980-3 covers specific requirements for electric road vehicle (EV) magnetic field

wireless power transfer (MF-WPT) systems including general background and definitions

(e.g. efficiency, electrical safety, EMC).

The requirements described in IEC 61980-1 are general. The technical requirements for the

various wireless power transfer (WPT) technologies are very different; they are specified in

the technology specific parts of the IEC 61980 series. A list of possible WPT technologies is

listed in IEC 61980-1. The requirements for magnetic field wireless power transfer systems

(MF-WPT) are described in this document. Further parts of the IEC 61980 series will describe

other technologies such as power transfer via electric field (EF-WPT) or via electromagnetic

field wireless power transfer systems (EF-WPT) or electromagnetic field-WPT systems, also

named microwave-WPT systems (MW-WPT).

Reference to "technology specific parts" always refers to each parts of the IEC 61980 series.

The structure of the "technology specific parts" follows the structure of IEC 61980-1.

WPT systems are still under development. For this reason, there is the future but not
