Today (May 27), Manitoba's first low carbon school bus successfully converted from diesel to electric power is rolling out of RRC Polytech's Vehicle Technology and Energy Centre (VTEC) - demonstrating the viability of a cost-effective unique process to electrify current fleets and reduce the environmental impact of using fossil fuels.
"Our work on the electric school bus conversion kit is the latest example of how applied research collaborations with industry partners support market-driven innovation and product development," said Fred Meier, President and CEO, RRC Polytech. "This project is an example of the applied research expertise and facilities RRC Polytech has developed over the last 20 years that contribute to advancing technologies to support Manitoba's energy transition."
Funded by the Government of Manitoba's Conservation and Climate Fund and the Canadian Shield Foundation, the diesel to EV school bus conversion kit is the result of a collaborative project that brought together the experts at RRC Polytech's VTEC, Noble Northern and Seven Oaks School Division. The conversion kit reduces greenhouse gases (GHG) emissions, cuts costs for schools and the government, and offers an affordable alternative to factory-built electric buses.
"Manitoba is committed to advancing clean transportation solutions that protect our environment while ensuring safe and sustainable mobility for students," said the Honourable Mike Moyes, Minister of Environment and Climate Change. "We're thrilled that the result of this collaboration - proof of concept for the conversion of diesel school buses to electric power - not only offers an alternative to importing costly technology, but the potential to stimulate our local economy through job creation and growth."
The project began in August 2023, when the Seven Oaks School Division provided a suitable bus for conversion and students from RRC Polytech's Heavy Equipment Mechanic Program removed its diesel engine before transferring the bus to principal industry collaborator, Noble Northern. VTEC's research team joined their experts on the groundwork for converting the bus, including the preliminary design for the electric drive system, which eventually led to the procurement of electric motors, batteries, controllers, inverters, and other essential accessories in the conversion kit. After the installation and commissioning phase, the newly converted electric school bus was returned to RRC Polytech for rigorous environmental performance evaluations within MotiveLab VTEC's climatic chamber.
"RRC Polytech's VTEC is proudly regarded as a Canadian leader in EV technology. By seeking cost-effective methods to reduce emissions and source renewable energies for fuel for fleet vehicles like school buses, we are helping to build and maintain a sustainable future while training the workforce of tomorrow," said Jojo Delos Reyes, Program Manager, Vehicle Technology and Energy Centre. "This project also allowed us to deepen our relationship with industry experts, Noble Northern and build on the knowledge that we acquired while working together converting the Arctic Tundra Buggy which will undoubtedly benefit our next partners and projects."
Even with labour costs considered, retrofitting an existing diesel bus using the conversion kit saves over $100,000 on the price of purchasing a new factory-built Type C electric school bus, freeing up valuable budget for administrators to reinvest directly into the classroom while still significantly reducing their carbon footprint. The benefits of converting just one bus also include saving up to $11,000 in fuel costs and reducing 21.6 tonnes of CO2 emissions per school year (approximately 39 weeks). Other advantages of switching to this technology include lower maintenance costs and elimination of air and noise pollution.
"This successful collaboration has proven what is possible - now we're ready to literally drive it forward," said Delos Reyes. "Our next steps are to explore commercialization and scaling possibilities of the conversion process and to connect with partners who are interested and motivated to adopt this new technology."
