IEC 61980-1:2015

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

IEC 61980-1:2015 applies to the equipment for the wireless transfer 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 1 000 V a.c. and up to 1 500 V d.c. This standard also applies to Wireless Power Transfer (WPT) equipment supplied from on-site storage systems (e.g. buffer batteries, etc.).
This publication is to be read in conjunction with the IEC 61980 series.
The contents of the corrigendum of January 2017 have been included in this copy.

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

L'IEC 61980-1:2015 s'applique aux matériels pour le transfert sans fil du réseau électrique aux véhicules électriques routiers afin de fournir de l'énergie électrique au RESS (système de stockage de l'énergie rechargeable) et/ou à d'autres systèmes électriques embarqués en fonctionnement lorsqu'ils sont raccordés au réseau électrique, à des tensions d'alimentation assignées normalisées conformément à l'IEC 60038, jusqu'à des tensions alternatives de 1 000 V et des tensions continues de 1 500 V. La présente norme s'applique également aux matériels de transfert de puissance sans fil (WPT) qui équipent les systèmes de stockage sur site (par exemple, batteries tampons, etc.). La présente version bilingue (2016-11) correspond à la version anglaise monolingue publiée en 2015-07.
Le contenu du corrigendum de janvier 2017 a été pris en considération dans cet exemplaire.
