ComEd, North Carolina State University receives federal grant to develop and demonstrate extremely fast charging for electric vehicles

Latest example of ComEd’s efforts to develop network innovations to reduce carbon emissions and air pollution

ComEd, in partnership with the FREEDM Systems Center at North Carolina State University, received a $200,000 Federal Research and Development Grant from the U.S. Department of Energy (DOE) to help fund a $5 million research project billion focused on improving efficiency and reducing the cost of super fast charging (XFC) for electric vehicles (EVs).

“The growth of electric vehicles has the potential to reduce harmful emissions and improve air quality for everyone, whether they drive or ride in an electric vehicle, but the time it takes to fully charge an electric vehicle can be a deterrent to consumers,” said Michelle BlaiseSVP Technical Services at ComEd. “ComEd engineers are industry-leading innovators, and we are honored to contribute our expertise and resources to find new technical solutions that will convince more consumers to switch to an electric vehicle. »

XFC will allow EV owners to charge their vehicles at a much faster rate than a Level 1 or Level 2 charger. Level 1 chargers, which rely on standard 120V outlets and AC power , are the slowest charging method available, taking approximately 50 hours to charge a standard 70kWh EV battery. Level 2 chargers use 240V outlets and take approximately 7.5 hours to fully charge a standard 70kWh battery.

The XFC charger that this project seeks to develop and demonstrate will be an ultra-low-cost modular silicon carbide power converter for DC charging equipment that can connect directly to a medium voltage distribution system. With power capacities of 300 kWh, these chargers aim to reduce the time to fully charge a standard 70 kWh EV battery to just 15 minutes.

“The goal of this new project is to bring super fast charging significantly closer to market realization and support the continued adoption of electric vehicles by reducing consumer charging anxiety,” said Srdjan Lukic, Ph.D., North Carolina State Professor, Deputy Director of FREEDM and Principal Investigator of the project. “We couldn’t achieve this without the collaboration of project partners like ComEd.”

The project will be divided into two phases focusing on cost analysis and system development and system demonstration, respectively. Once the charging systems are developed, ComEd’s Grid Integration and Technology (GrIT) lab in Maywood, Illinois will serve as the initial testing location for this new technology, providing independent validation of XFC system performance. ComEd will also support phase two of the project by identifying ideal locations on the distribution network to demonstrate this technology, unlocking the potential for wider deployment.

The $5 million XFC EV development and demonstration project is funded by collaborator cost-sharing, including $200,000 from ComEd. Other collaborators on this project include Danfoss, GoTriangle, the New York Power Authority and the North Carolina Clean Energy Technology Center.

The ComEd GrIT Lab reinforces ComEd’s commitment to supporting the grid of the clean energy future for its customers. The lab focuses on the impacts that increased levels of renewable and beneficial electrification technologies will have on the grid. Previous GrIT Lab projects include the Bronzeville Community Microgridthe first utility-operated microgrid cluster powered by DERs and controllable gas generation, and the ComEd Distribution Linear State Estimator, a software application that processes field data to estimate voltages, currents and electrical power flows from the system to the distribution network to improve the system remotely. monitoring and control capabilities.

Commonwealth Edison Company (ComEd) is a unit of Chicago-based Exelon Corporation (NASDAQ: EXC), the nation’s leading competitive energy provider, with approximately 10 million customers. ComEd provides services to approximately 4 million customers in northern Illinois, or 70% of the state’s population.
