Electric vehicle wireless power transfer (WPT) systems. Specific requirements for magnetic field wireless power transfer systems | Status: Current

1 Scope 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 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 mountedprimary 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.

NOTE The terms used in this document are specifically for MF-WPT.
