New tech eases range anxiety for electric cars and buses
Company is paving the way for the future of e-mobility.
Electric cars and buses are great, but their batteries have limited range. You can only go so far without running out of juice. It’s called “range anxiety,” and it’s often cited as the No. 1 reason people are reluctant to buy electric vehicles.
Now, an Israeli company called ElectRoad has come up with an ingenious solution to help ease range anxiety and put more electric buses on the road. It's the third company founded by serial entrepreneur Oren Ezor, a graduate of the Technion Institute in Israel.
Many cities around the world already have an electric-powered public transportation system, but the overhead wires that power the buses are an eyesore, not to mention potentially dangerous.
What ElectRoad proposes to do is bury the electric charges underneath bus lanes on city streets, much like we bury modern telephone and power lines for private homes and businesses. It’s called Dynamic Wireless Power Transfer, and it’s the same technology that wirelessly recharges your electric toothbrush or smartphone.
It’s actually a pretty simple idea: If you change an electric current, it creates a changing magnetic field, which will induce an electric current into a nearby wire even without a physical connection. So by embedding wire coils into the road, electric vehicles traveling over the road could be charged even while driving.
ElectRoad says the wireless charging lanes will both increase the market share for electric vehicles and contribute toward meeting the environmental demands of future mobility, reducing emissions and cost of operation.
The company recently won a grant from the European Union’s Horizon 2020 program to further development of its technologies. While the company's vision is still in its early stages, it also hopes to one day produce technology to send charging currents from car to car.
