The Central Florida Expressway Authority (CFX) has partnered with Advancing Sustainability through Powered Infrastructure for Roadway Electrification (ASPIRE) to test a mechanism in Central Florida that charges electric vehicles (EVs) on the go. CFX has installed approximately one mile of dynamic wireless induction charging on the proposed five-mile Lake/Orange Expressway that will charge EVs as they drive on this stretch.
The innovative patented ENRX technology (former IPT Technology) works through wireless inductive power transfer. It infuses charge into the battery as the vehicle drives over the lane. Energy flows from the pre-assembled ground winding coils to a receiver pad under the vehicle through electromagnetic induction – a technology widely in using for charging things like electric toothbrush or cell phone. The technology can detect when an electric vehicle is directly above it, making the lane safe for all other drivers to use, as well as the surrounding environment. “This is a game changer for speeding up the energy transition, said Richard van den Dool, Vice President Charge.
The ENRX Charge 200 kW Electrified Roadway Technology will be able to power all vehicle classes using the roadway. The vehicle types include passenger cars, medium-duty delivery vans, and heavy-duty trucks and buses. The solution provides comparable benefits including dynamic charging, high power, flexibility, and safety. With more than 25 years of experience in testing and installing this equipment in concrete with several pilots in Europe, ENRX has successfully tested it with charging powers of 180 kW, and driving speed of 50 mph and overall efficiency of more than 90%.
The benefits of this technology include elimination of range anxiety and long charging time. Thus, it would be much easier to charge EVs while driving. “As a roadway agency, it is exciting to work with ASPIRE and ENRX to pilot this emerging technology that has the potential to make a significant impact on the future of roadway infrastructure nationwide,” said CFX Chief of Infrastructure Glenn Pressimone.
