If Canada wants mass adoption of EVs it needs a fast charging network and a uniform set of standards to govern it, says the CSA Group

CSA Group has been engaged in activities supporting the development and implementation of EV charging technologies and their harmonization across North America since 2010.
As Canada aims for 100 per cent zero-emission new vehicle sales by 2035, we need to prepare our infrastructure for the growing number of electric vehicles (EVs) on the road. This is no small task.
To tackle the issue of insufficient charging infrastructure, the federal government has promised $680 million to build more stations across the country.
Collaboration with utilities is critical for advancing generation and transmission infrastructure capabilities to meet increased demand.
The role of standards in electrifying transportation
The challenges faced by the transportation sector, electrical utilities, and manufacturers can be partly addressed through codes and standards. These may address the quality, safety and performance of services, products and systems.
Moreover, standards encourage compatibility and interoperability, promote environmental protection and enhance trade.
When harmonized at the national, regional, or international level, codes and standards can help reduce the regulatory burden by aligning common requirements and ultimately reducing time-to-market and costs for manufacturers.
Fast-charging infrastructure is critical for mass EV adoption
The widespread adoption of battery EVs depends greatly on the availability of reliable DC fast charging infrastructure. This type of charging is necessary for long-distance travel and allows drivers to charge up to 80 per cent in about 30 minutes.
This infrastructure delivers high power. Being used by the public, it is crucial to prioritize its safety.
The new standard, CSA C22.2 No. 346:22, DC charging equipment for electric vehicles, published in December 2022, addresses this challenge.
The standard, developed at the request of industry and manufacturers, provides safety requirements for the construction, performance, testing and marking of DC fast charging equipment in North America. It also addresses protection of users against injury.
Using the standard CSA C22.2 No. 346, manufacturers have clarity on the safety requirements for their products. Conformity assessment bodies can use the standard as a means to test and certify products for electrical safety compliance.
While CSA C22.2 No. 346 provides requirements for the development and safe operations of electric vehicle DC fast charging supply equipment in the Canadian context, the standard is also accepted in the U.S. and Mexico, helping ensure compatibility and interoperability of systems across North America.
Systemic approach to integrating battery electric vehicles
The CSA’s standardization approach helps to seamlessly integrate EVs into the electrical system.
Addressing techniques such as energy management, bi-directional power transfer, and energy storage will help overcome the challenges of increased energy demand and support the widescale adoption of EVs.
Our standards also support the adoption of EVs for various transportation modes, contributing to broader electrification and decarbonization of the transportation sector.
