Transport Electrification - STL to test two electric buses with a range extender

June 22, 2017

In the aims of gradually rendering its entire fleet of buses electric within the next few years, the Société de transport de Laval (STL) will, effective this year, be testing two electric buses with range extenders. The vehicles will have a range of at least 35 kilometres in electric mode. Through this pilot project, the STL intends to broaden its knowledge into electric transport modes so that it can tailor its future technology choices all while encouraging Quebec-based electromobility subsidiaries. At a cost of 8.5 million dollars, the project was made possible thanks to a 4.25-million-dollar financial contribution by the Ministry of Energy and Natural Resources and to the expertise and contribution of TM4 and Cummins.   

This 18-month experiment will see the STL acquire one rapid charging station which will be installed near the Cartier metro station. The STL thanks Hydro-Québec and the new Metropolitan Regional Transportation Authority for supporting the charging station project. The results from this test will help further expand Quebec expertise in transport electrification. It should be noted that, in 2012, the STL was the first public transit corporation in Canada to acquire a 40-foot 100% electric bus.

“Over the last few years, the STL tested several electric propulsion technologies on Laval territory. I am elated that the Government of Quebec put its faith in the STL, an innovative corporation, so that it may contribute to the development of Quebec electromobility subsidiaries. The STL’s transport electrification plan is in perfect alignment with Laval’s strategic plan in its objectives to cut greenhouse gas (GHG) emissions on its territory”, stated Laval mayor Marc Demers.  

“A leader in electrification since 2012, the STL keeps constantly scanning developments in public transport electrification. Thanks to our engineering team’s sense of initiative, we have developed cutting edge expertise in testing various electric vehicles. In this current project, the tests will guide our investment decisions based on our operating reality. Our objective is to eventually acquire only electric vehicles”, emphasised STL Board President David De Cotis.

“TM4 has always innovated in order to meet market requirements”, affirmed Robert Baril, Director General of TM4. “These days, our clients are able to purchase limited range electric or hybrid buses. Our aim is to put out a system that can attain a minimum range of 35 km and to benefit from rapid charging infrastructure performance of less than 5 minutes at a force of 450 kW. The range extender offers peace of mind and important flexibility for public transit corporations such as the STL, which plans its bus routes with interlineation,” concluded Mr. Baril.

The main interest in this project lies in combining the rapid charging mode with the vehicle’s range extender. This innovative technology allows us to benefit from the advantages of electric propulsion while simultaneously benefiting from higher range than that of a hybrid vehicle. The STL is proud to contribute to the development of Quebec electromobility subsidiaries.  

“The integration and management of system controls of an electric traction system with an appropriately matched diesel motor are key constituents to the development of an electric range-extender-equipped vehicle motorisation system. Cummins appreciates the opportunity to put its transport expertise into supporting the Government of Quebec’s vision on transport electrification. The Cummins sales and service team stands ready to offer its support”, stated Jeff Van Poucke, Cummins sales and service president for Eastern Canada.
