1 Scope
This part of IEC 61980, which is a Technical Specification, applies to the equipment for the magnetic field
wireless power transfer (MF-WPT) 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. The MF-WPT system
operates at standard supply voltages ratings per IEC 60038 up to 1 000 V AC and up to 1 500 V DC The power transfer takes place while the electric
vehicle (EV) is stationary.
This document also applies to MF-WPT equipment supplied from on-site storage systems
(e.g. buffer batteries) at standard supply voltages ratings per IEC 60038 up to 1 000 V AC and up to 1 500 V DC.
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 two- and three-wheel vehicles,
-
– requirements for MF-WPT systems supplying power to EVs in motion, and
-
– requirements for bidirectional power transfer.
This standard 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.
