Wirelessly Charging Electrical Vehicles

A Stanford University research team has designed a high-efficiency charging system that uses magnetic fields to wirelessly transmit large electric currents between metal coils placed several feet apart. The long-term goal of the research is to develop an all-electric highway that wirelessly charges cars and trucks as they cruise down the road.

00:00:01 [Music] Stanford University this is a vehicle running on the highway we have a series of Cs embedded in the highway for this skin we are uh using the near field magnetic field to transfer the energy wirelessly this is used as a source coil and the coil under the car is used as the pickup coil when the car is driving

00:00:45 by the energy is transfer wirelessly from The Source coil to the pickup coil eventually we would like to charge the electrical vehicle on the highway when it's running there is this anxiety for the electrical Vehicles so uh if we can actually charge the uh electrical vehicle when it's running on the highway then we can solve this problem for more please visit us at
