University of Colorado-Boulder (CU Boulder) researchers are working on the development of electric vehicles that one day may be able to charge while driving down the highway, drawing wireless power directly from plates installed in the road.
Such an arrangement could allow cars to drive thousands of miles without having to plug in for a recharge.
CU Boulder professor Khurram Afridi and colleagues have spent the past two years creating a proof of concept for wireless power transfer that transfers electrical energy through electric fields at very high frequencies.
Enabling the transfer of large amounts of energy across greater physical distances to in-motion platforms from low-cost charging plates would expand the technology's potential applications beyond small consumer electronics.
The technology can now transmit kilowatts of power at megahertz-scale frequencies. In the near future, Afridi says, the technology could help warehouses eliminate the need to idle robots and forklifts for recharge.
