Technology for wireless in-vehicle charging of personal devices to be developed by electronics firm Powermat and used in GM models starting in 2012.

GM and electronics firm Powermat have announced a new partnership to develop wireless charging technology for personal devices to be used in GM vehicles.

GM Ventures, the automaker's investment arm, will invest $5 million in Powermat to create a "mat" technology for wireless charging of hand-held electronics such as mobile phones in future Buick, Chevrolet, Cadillac and GMC models. The technology is scheduled to be ready by mid-2012.

Powermat already sells wireless charging devices for the home to consumers at major U.S. retail outlets such as Wal-Mart and Best Buy.

"Imagine a mat or shelf where you could put your iPhone, your Droid or other personal device and charge it automatically while you commute to work, run errands or as you're driving on a family vacation," said Micky Bly, GM executive in charge of electronics.
