Electric vehicle wireless power transfer (WPT) systems -- General requirements
This Part of IECÂ 61980 applies to the supply device for charging electric road vehicles using wireless methods at standard supply voltages per IECÂ 60038 up to 1Â 000Â V AC and up to 1Â 500Â 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.
