Cornell researchers are trying to build a future where electric vehicle owners can charge their cars wirelessly without stopping. We’ve seen ideas for “plugless EV charging”
Charging is one of the biggest obstacles for electric vehicles at the moment. A recent report suggests that 1 in 5 electricity owners in California are switching back to gas because finding and waiting for chargers is a hassle and potentially dangerous.
However, researchers at Cornell University have developed technology that can turn our ways into wireless chargers. It is a system where drivers only have to change lanes to top up the battery.
Cornell Electrical and Computer Engineer Khurram Afridi has been working on the technology for the past seven years and wants to put wireless charging strips on the highway. Like toll roads, you can drive up a loading lane, refill the juice and pay for everything at the same time. Either that, or get a bill later if you haven’t paid your toll.
This also applies not only to electric vehicles. Cornell engineers say this can work with electric vehicles, autonomous forklift trucks and other mobile machines, while keeping them moving.
Afridi and his team use an idea that is more than 100 years old by Nikola Tesla. In short, creating a charging system that would use two insulated metal plates on the ground and a high frequency inverter to create oscillating electric fields. Then, EV cars can attract and repel those charges with similar metal plates underneath the vehicle. Rather than a magnetic charging field, which is a closed loop, this is an open-ended system that operates while the receiving device is still moving and passing through the electric fields.
Neat, right? Obviously, a project like this requires government and state approval, not to mention millions of dollars invested in road and highway upgrades. However, Afridi sees this as a way to build an infrastructure that matches the technology that is available now and in the future.
