In Canada, transportation contributes over 23% of annual greenhouse gas (GHG) emissions. A key component of strategies to reduce GHG emissions in the transportation sector is the electrification of public transit via electric buses (e-Buses). The wide adoption of e-Buses necessitates advanced solutions for charging facilities that can handle high power, operate with high reliability, and have a small footprint. Moreover, to reduce stress on electrical infrastructure, a local energy storage system (ESS) will be important to shave the peak power demand of an e-Bus charging facility. This project addresses the above needs by designing and testing a high-power ESS-ready fast charger system for e-Buses. The project is a collaboration among a power electronics expert at the University of Alberta, a smart energy management expert at the University of Calgary, and industry partner eCAMION, a solution provider for the energy storage industry. The final outcome of the project will be a fully functional fast charger hardware and control prototype that will be an integral part of an e-Bus charging station. The project will provide vital knowledge and solutions to Canadian electric vehicles and e-Bus industries.
