English -- Electric vehicle wireless power transfer (WPT) systems – Part 3: Specific requirements for the magnetic field wireless power transfer systems - Edition 1.0

Abstract

Scope: This part of IEC 61980, which is a Technical Specification, applies to the equipment for the magnetic field wireless power transfer (MF-WPT) of electric power from the supply network 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 voltages ratings per IEC 60038 up to 1 000 V AC and up to 1 500 V DC The power transfer takes place while the electric vehicle (EV) is stationary. This document also applies to MF-WPT equipment supplied from on-site storage systems (e.g. buffer batteries) at standard supply voltages ratings per IEC 60038 up to 1 000 V AC and up to 1 500 V DC. 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 MFWPT 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 two- and three-wheel vehicles, – requirements for MF-WPT systems supplying power to EVs in motion, and – requirements for bidirectional power transfer. 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.
