Israeli start-up ElectReon developed a wireless “smart road” system that charges electric vehicles
(EVs) while in full motion. The wireless charging system was named in the annual list of TIME
magazine’s 100 Best Inventions for 2021.
Founded in 2013, ElectReon’s wireless charging system uses copper coils laid beneath the
asphalt to transfer energy from the electricity grid to the road and to manage communication
with approaching vehicles. Receivers are installed on the floor of the vehicles to transmit the
energy directly to the engine and the battery while the vehicles are on the go, doing away with
concerns about limited driving range and short battery lifespans.
The company signed a new deal with the Tel Aviv-Jaffa Municipality and the Dan Bus Company
to launch a large-scale commercial deployment of its wireless charging infrastructure to power
electric buses in Tel Aviv. In summer 2021, ElectReon welcomed former Israeli president
Reuven Rivlin as company president to “enhance the company’s collaboration with governments
and global companies, as well as to share our activities with decision-makers around the world.”
ElectReon is based in the northern Israeli community of Beit Yannai. It has a number of running
partnerships in Europe to pilot its smart road tech in Germany, France and Belgium. In Sweden,
ElectReon has installed a 1.65-kilometre electric stretch used by a bus and a truck on the 4.1
kilometres route between the airport and town centre of Visby on Gotland Island.
“We are honoured by the recognition of ElectReon’s wireless charging solution by TIME as we
work to spread awareness on the viability of this technology in maximizing fleet owner vehicle
efficiencies, eliminating the cost of fuel, and reducing their full lifecycle carbon emissions,” said
ElectReon CEO Oren Ezer in a statement. “As we rapidly scale our deployments around the
world, we envision this technology to play a key role in accelerating the mass transition towards
total electrification and we look forward to continuing to build the transportation infrastructure
of tomorrow with the ongoing outstanding support from our industry and governmental partners
we have experienced until now.”
ElectReon was listed in the transportation category.
