We often see wireless chargers for low-power devices such as phones and tablets, but it's certainly possible to use the same technology to power larger products, including EVs. The challenge is that it takes a long time to power an EV with pure wireless charging – up to 8 hours for a full charge. Current methods have clocked the power transfer at 3kW, 11kW, even up to 40kW. 

A team of researchers at Oak Ridge National Laboratory (ORNL) in Tennessee recently reported they hit 100kW, with 96% efficiency (meaning minimal energy loss during transfer), and they claim they can get to 120kW power delivery “with potential to deliver more power still”.

That's an incredible leap in capability and perhaps something that would make wireless charging more realistic for EVs. Instead of 8 hours you could wirelessly charge a battery to drive 350 miles in just one hour. 

Still a lot of research to be done, but the technology is moving faster and faster every day.
