Spatial wireless power transfer based on multiple magnetic resonances - Part 1: Requirements (IEC 63245-1:2021)

This part of IEC 63245 specifies requirements for spatial wireless power transfer based on
multiple magnetic resonances (SWPT-MMR), which is a non-radiative wireless power transfer
(WPT). This document contains two categories of requirements: general requirements and
functional requirements. The general requirements cover charging procedures and charging
zones. The functional requirements cover each component of a SWPT-MMR system, such as
transmitter coils.

L'IEC 63245-1:2021 spécifie les exigences relatives au transfert d’énergie sans fil dans l’espace reposant sur des résonances magnétiques multiples (SWPT-MMR), qui est un mode de transfert d’énergie sans fil (WPT) non radiatif. Le présent document contient deux catégories d’exigences: les exigences générales et les exigences fonctionnelles. Les exigences générales couvrent les procédures de charge et la zone de charge. Les exigences fonctionnelles couvrent chaque composant d’un système SWPT-MMR (les bobines de transmission, par exemple).

SPATIAL WIRELESS POWER TRANSFER

Part 1: 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 63245-1 has been prepared by technical area 15: Wireless power
transfer, of IEC technical committee 100: Audio, video and multimedia systems and equipment.

INTRODUCTION
The IEC 63245 (Spatial wireless power transfer based on multiple magnetic resonances,
SWPT-MMR) series provides requirements and a reference model for implementing a spatial
wireless power transfer system. The IEC 63245 series consists of the following parts:
– IEC 63245-1: Spatial wireless power transfer based on multiple magnetic resonances –
Part 1: Requirements, which describes requirements of SWPTs with multiple magnetic
resonances; and
– IEC 63245-2: Spatial wireless power transfer based on multiple magnetic resonances –
Part 2: Reference model, which describes a reference model for SWPTs with multiple
magnetic resonances.
