• Informing infrastructure deployment where WPT integrates with on‑site storage or grid connections

Who will use it:

• EV charging equipment manufacturers and system integrators
• Automotive OEMs and electrical engineers implementing WPT interfaces
• Test laboratories and certification bodies
• Utilities, site operators and standards committees evaluating WPT installations

Related Standards

• IEC 61980 series (technology‑specific parts: IEC 61980‑2, IEC 61980‑3)
• IEC 60038 (standard voltages)
• EMC/EMI and immunity standards (IEC 61000 series, CISPR)
• IEC 60364‑7‑722 (supplies for electric vehicles), ISO 17409 and other normative references cited in EN IEC 61980‑1:2021

Part 1: General 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-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 61980-1 has been prepared by IEC technical committee 69:

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, EMF);
• IEC 61980-2 specifically applies to magnetic field wireless power transfer (MF-WPT) for
electric road vehicles and covers specific requirements for system activities and
communication between the electric road vehicle side and the off-board side including
general background and definitions;
• IEC 61980-3 covers specific power transfer requirements for the off-board side of magnetic
field wireless power transfer systems for electric road vehicles (e.g. efficiency, electrical
safety, EMC, EMF).
The requirements described in this document are general. The technical requirements for the
various wireless power transfer technologies are specific. The requirements for magnetic field-
wireless power transfer systems are described in IEC 61980-2 and IEC 61980-3. Further parts
of this series are reserved to other technologies.
Reference to "technology specific parts" always refer to other parts of the IEC 61980 series.
