Electric vehicle wireless power transfer (WPT) systems - Part 3: Specific requirements for magnetic field wireless power transfer systems.

IEC 61980-3:2022 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 mounted primary 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.

IEC 61980-3:2022 is to be used in conjunction with IEC 61980-1:2020.
