Electric vehicle wireless power transfer (WPT) systems - Part 4: Interoperability and safety of high-power wireless power transfer (H-WPT) for electric vehicles

Scope

IEC PAS 61980-4:2025 applies to the off-board supply equipment for high-power wireless power transfer (H-WPT) via magnetic field (MF-WPT) to electric road vehicles for purposes of supplying electric energy to the RESS (rechargeable energy storage system) or other on-board electrical systems, or both.

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.

The aspects covered in this document include

– the characteristics and operating conditions,

– specific power transfer requirements for the off-board side of magnetic field high-power wireless power transfer systems for electric road vehicles,

– 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

This document does not apply to

– safety aspects related to maintenance, and

– trolley buses, rail vehicles and vehicles designed primarily for use off-road
