Canada: Wireless system charges electric vehicles

VICTORIA, British Columbia, Oct. 29 (UPI) — Canadian researchers say they’ve developed a safe, efficient technology to wirelessly charge electric vehicles using “remote magnetic gears.”

“Wireless charging has been a much sought-after technical solution for everything from cellphones to electric cars,” University of British Columbia physics Professor Lorne Whitehead says.

“A significant concern for charging cars wirelessly has been the high power and high frequency electromagnetic fields and their unknown, potential health effects on humans.”

A system invented by Whitehead and his research team operates at a frequency 100 times lower and with negligible exposed electric fields, a UBC release reported Monday.

Their system uses “remote magnetic gears” — a rotating base magnet driven by electricity from the grid, and a second located within the car — to eliminate the use of radio waves.
