This project piloted a smart EV charging solution at the University of Alberta car parks. As EVs become more prominent, commercial buildings will have the greatest potential to minimize charger deployment costs and reduce energy consumption emissions generated by EV charging.

Commercial buildings play an important role in decarbonizing the transportation sector, which is the largest GHG emission contributor in Canada. EVs, when coupled to a building’s electrical systems as a new power load, pass on energy consumption and GHG emissions from transportation to buildings, thus exacerbating building contribution to emissions.

The innovation is in the use of a combined dynamic demand management and emission signal-based control. It is different from the equal power sharing approach coupled with high current 48A electric vehicle charging stations.

Project Innovation

Smart EV charging solution

The intent of this pilot program is to address some of the issues of EV and building unification.

It addresses peak demand loads, and costs associated with overall infrastructure upgrades.

The solution proposes to install high-current, level-2, smart EV chargers and a Central Charger Management system (CCMS) with demand-control capabilities. The ability to use this software and restrict peak demand loads will result in a reduced fee for overall infrastructure upgrades, while potentially increasing the number of charging stations.

The project will pilot the smart EV charging solution in University of Alberta car parks where the data projected and collected for the claims on energy savings and emissions reductions can be calculated and compared with projections. There will be a total of 20 EVs installed and monitored with the CCMS platform, and they will be integrated with an existing PV station.

Upon successful deployment of the project, a standard solution will be generated to scale up the technology for larger campus and commercial projects.
