Scope:

Note: As requested by the responsible SDO, this NOI being reissued as the standard was in the initial stages of development for more than 12 months. An additional comment period of March 25 to April 15 25, 2025 (originally published on March 26, 2024).
 

Note: The designation number for this NOI (originally published on March 26, 2024) was updated by the responsible SDO on March 18, 2025.

 

This part of the standard 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. 
C22.2 No. 61980-3 is to be used in conjunction with C22.2 No. 61980-1. 

Project need:

With the increasing adoption of electric vehicles (EVs) worldwide, the need for advanced charging methodologies has increased. The adoption of this standard will help align Canadian requirements with those of international standards in the area of charging electric road vehicles using wireless methods for regulators, utilities, and manufacturers. This forms part of the wireless power transfer standard series, C22.2 No. 61980.
