Wireless charging for cars in development

Larisa Brass, writing for the News Sentinel, reports that researchers at Oak Ridge National Laboratory are working on a magnetic charging system for vehicles, eliminating the need to plug in for charging.

The idea has been several years in the making, and engineers now have a proof of concept, said Mitch Olszewski, director of power electronics and electrical power systems research at ORNL's National Transportation Research Center.

Studies cited by Olszewski show that up to 90 percent of utility workers with electric vehicles forgot to plug in their vehicles.

"What (behavior studies) find is people most apt to plug their vehicles in make it part of a routine," he said. "People that don't have that kind of a routine, they're less likely to plug it in," he said.

Although other research groups are working on the problem, Olszewski and Matthew Scudiere, a retired researcher at the NTRC who came up with the idea and is leading its development for ORNL on a contract basis, said their technology offers an efficient charge - 90 percent or more, depending on how far the battery sits from the charging station.

The current system uses antennas that emit an electromagnetic wave, the transmitter and receiver magnetically connect to transfer electricity from source to battery. As the product develops, it will be incorporated into a mat connected to a power source that a vehicle could simply park on during charging stops, Scudiere said.

The researchers say the system's components are simple and available, and so should not add significantly to the cost of installing a 220v charging line for electric car owners.
