Electric vehicle wireless power transfer (WPT) systems - Part 1: General requirements

IEC 61980-1:2020 applies to the supply device for charging electric road vehicles using wireless methods at standard supply voltages per IEC 60038 up to 1 000 V AC and up to 1 500 V DC. Electric road vehicles (EV) covers road vehicles, including plug-in hybrid road vehicles (PHEV) that derive all or part of their energy from on-board rechargeable energy storage systems (RESS). This document also applies to wireless power transfer (WPT) equipment supplied from on-site storage systems (e.g. buffer batteries). The aspects covered in this document include • the characteristics and operating conditions of a supply device, • the specification for required level of electrical safety of a supply device, • communication between EV device and vehicle to enable and control WPT, • efficiency, alignment and other activities to enable WPT, and • specific EMC requirements for a supply device. The following aspects are under consideration for future documents: • requirements for MF-WPT systems supplying power to EVs in motion; • requirements for bidirectional power transfer. This document does not apply to: • safety aspects related to maintenance, • WPT system for trolley buses, rail vehicles and vehicles designed primarily for use off‑road, and • any safety or EMC requirements for the vehicle side. IEC 61980-1:2020 cancels and replaces the first edition published in 2015. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) the contents of IEC 61980-1:2015 have been re-organized so that this document is generally applicable to any WPT technologies; b) technology specific requirements, mostly for MF-WPT in the main text of IEC 61980-1:2015, have been transferred to IEC 61980-2 and IEC 61980-3; c) Annex A, Annex B and Annex C have been removed and contents of these annexes have been transferred to the relevant technology specific parts of the IEC 61980 series; d) duplications and overlaps of the requirements within IEC 61980-1:2015 have been resolved; e) terms and definitions which are specified in IEC 61851-1:2017 and are applicable for WPT system have been directly described in this document, with modification for some terms. The reference to IEC 61851-1 is withdrawn.

Kontaktlose Energieübertragungssysteme (WPT) für Elektrofahrzeuge - Teil 1: Allgemeine Anforderungen

Systèmes de transfert de puissance sans fil (WPT) Pour véhicules électriques - Partie 1: Exigences générales

L'IEC 61980-1:2020 s'applique aux dispositifs d'alimentation pour la charge des véhicules électriques routiers au moyen de technologies sans fil, à des tensions d'alimentation normalisées conformément à l'IEC 60038, jusqu'à des tensions alternatives de 1 000 V et des tensions continues de 1 500 V. Les véhicules électriques (VE) routiers couvrent les véhicules routiers, y compris les véhicules routiers hybrides rechargeables (VEHR), qui tirent tout ou partie de leur énergie de systèmes rechargeables de stockage d'énergie (RESS) embarqués. Le présent document s'applique également aux matériels de transfert de puissance sans fil (WPT) qui équipent les systèmes de stockage sur site (par exemple, batteries tampons). Le présent document couvre les aspects suivants: • les caractéristiques et conditions de fonctionnement d'un dispositif d'alimentation; • la spécification concernant le niveau exigé de sécurité électrique d'un dispositif d'alimentation; • la communication entre le dispositif du VE et le véhicule pour permettre et contrôler le WPT; • le rendement, l'alignement et autres activités pour permettre le WPT; et • les exigences de CEM spécifiques pour un dispositif d'alimentation. Les aspects suivants sont à l'étude pour de futurs documents: • les exigences concernant les systèmes MF-WPT qui alimentent les VE en mouvement; • les exigences concernant le transfert de puissance bidirectionnel. Le présent document ne s'applique pas: • aux aspects de sécurité relatifs à la maintenance; • aux systèmes WPT pour trolleybus, véhicules ferroviaires et véhicules conçus principalement pour une exploitation non routière; • aux exigences de sécurité ou de CEM côté véhicule. L'IEC 61980-1:2020 annule et remplace la première édition parue en 2015. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) le contenu de l'IEC 61980-1:2015 a été réorganisé de sorte que le présent document soit généralement applicable à toutes les technologies WPT; b) les exigences spécifiques à la technologie, principalement pour le transfert de puissance sans fil par champ magnétique, dans le texte principal de l'IEC 61980-1:2015 ont été transférées dans l'IEC 61980-2 et l'IEC 61980-3; c) les Annexes A, B et C ont été supprimées et le contenu de ces annexes a été transféré dans les parties spécifiques à la technologie pertinentes de la série IEC 61980; d) les redondances et les chevauchements des exigences de l'IEC 61980-1:2015 ont été résolus; e) les termes et définitions qui sont spécifiés dans l'IEC 61851-1:2017 et qui sont applicables au système WPT sont directement décrits dans le présent document, avec des modifications pour certains termes; la référence à l'IEC 61851-1 a été supprimée.

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 agreemen
