Israel Tests Wireless Charging Roads for Electric Vehicles

Electric vehicles have long been a promising option for sustainable transportation. They come with practical headaches like expensive, bulky batteries that often need recharging, however. Israel is tackling those hurdles by investing in roads that power electric buses—as they ride down the street. The government is collaborating with Israeli start-up ElectRoad to install a public bus route in Tel Aviv, using an under-the-pavement wireless technology that eliminates the need for plug-in recharging stations.
Although still in its infancy, the technology could clear the three biggest hurdles—cost, weight and range—that have held back the widespread adoption of battery-powered vehicles for more than a century. First, though, ElectRoad will have to demonstrate that its “inductive charging” technology can be scaled up cheaply enough to be adopted on roadways worldwide. “It’s exciting because it’s charging without wires,” says Tim Cleary, director of BATTERY, an energy-storage research laboratory at The Pennsylvania State University, who is not involved in the project. “But unless it’s affordable and cost-effective it’s not going to take off.”
