HAWTHORNE, Calif. (AP) - Tesla Motors Inc. is unveiling a solar-powered charging station that it says will make refueling electric vehicles on long trips about as fast as stopping for gas and a bathroom break in a conventional car.

CEO Elon Musk said at a news conference Monday night at the company's design studio in Hawthorne, Calif., that the company's roadside Supercharger already has been installed at six highway rest stops in California.

Musk says the stations are designed to fully charge a Tesla sedan in about an hour, and that a half-hour-long charge would produce enough energy for a three-hour trip.

He says his Palo Alto-based company plans to have more stations running throughout California and in parts of Nevada and Oregon by the end of the year.
