Below is the text version for the "Wireless Charging for Electric Vehicles" video.

The video opens with a shot of an electric vehicle, showing the parts involved in charging: the transmitting plate, receiving plate, controller, and battery.

Charging is getting a whole lot easier for electric vehicles. Pretty soon you won’t even have to plug-in to power up. Hi, I’m Nay Chehab in the Energy Department’s Vehicle Technologies Office.

Going wireless is the dream for most consumers, and thanks to a project we’re supporting with Oak Ridge National Laboratory, EV drivers could soon be pulling the plug on their charging stations.

The lab’s wireless power transfer project recently received a special recognition award by R&D magazine for innovation.

The video shows cars being tested on in the laboratory, with the subtitle: Wireless Power Transfer.

The lab teamed up with industry to develop the world’s first 20-kilowatt wireless charging system for passenger cars. The electric current is transferred by creating a magnetic field between a transmitting pad on the ground and a receiving pad located under the vehicle.

The system is 90% efficient while charging at three times the power rating of a conventional charger. This means that you can recharge an average all-electric vehicle in one to two hours or a hybrid plug-in in less than an hour.

Just the idea of being able to pull up over the top of a charging pad, get out of my vehicle and walk away… That’s a huge convenience issue for me and a big benefit.

Oak Ridge is one of 11 national labs taking home an R&D 100 award for outstanding technology development. Thirty-two out of the top 100 innovations recognized by the magazine were supported by the Energy Department.
