UNE-EN IEC 61980-3:2022

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 MF111 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, and

requirements for bidirectional power transfer.

requirements for flush mounted primary devices

requirements for MF-WPT systems for heavy duty vehicles

requirements for MF-WPT systems with inputs greater than 11,1 kVA

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.
