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

2Scope / Description

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 kVAThis 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.
