1 Scope
This part of IEC 61980 applies to the off-board supply equipment for wireless power transfer via magnetic
field (MF-WPT) to electric road vehicles for purposes of supplying electric energy to the RESS
(rechargeable energy storage system) and/or other on-board electrical systems. The
MF-WPT system operates at standard supply voltage ratings per IEC 60038 up to 1 000 V AC and up to 1 500 V DC from the supply network. The power transfer
takes place while the electric vehicle (EV) is stationary.
Off-board supply equipment fulfilling the requirements in this document are intended
to operate with EV devices fulfilling the requirements described in ISO 19363.
The aspects covered in this document include
-
— the characteristics and operating conditions,
-
— the required level of electrical safety,
-
— requirements for basic communication for safety and process matters if required by
a MF-WPT system,
-
— requirements for positioning to assure efficient and safe MF-WPT power transfer, and
-
— specific EMC requirements for MF-WPT systems.
The following aspects are under consideration for future documents:
-
— requirements for MF-WPT systems for two- and three-wheel vehicles,
-
— requirements for MF-WPT systems supplying power to EVs in motion,
-
— requirements for bidirectional power transfer,
-
— requirements for flush mountedprimary device,
-
— requirements for MF-WPT systems for heavy duty vehicle, and
-
— requirements for MF-WPT systems with inputs greater than 11,1 kVA.
This document does not apply to
-
— safety aspects related to maintenance, and
-
— trolley buses, rail vehicles and vehicles designed primarily for use off-road.
NOTE The terms used in this document are specifically for MF-WPT.
