Electric vehicle wireless power transfer systems (WPT) - Part 1: General requirements

This part of the standard applies to the equipment for the wireless transfer 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 in an operational state when connected to the supply network, at standard. supply voltages ratings per IEC 60038 up to 1000V a.c. and up to 1500 V d.c.

This standard also applies to Wireless Power Transfer (WPT) equipment supplied from on-site storage systems (e.g. buffer batteries etc.).

The aspects covered in this standard include:

– the characteristics and operating conditions;

– the specification for required level of electrical safety;

– requirements for basic communication for safety and process matters if required by a WPT system;

– requirements for basic positioning, efficiency and process matters if required by a WPT system.

– requirements for WPT system while driving (under consideration);

- trolley buses and rail vehicles

– specific EMC requirements for WPT systems.

This standard does not apply to:

– safety aspects related to maintenance;

– WPT vehicle power supply circuit, which is covered by ISO 6469 series; ISO 193631

– EMC requirements for on-board equipment while connected, which are covered in IEC 61851-21-12.
