At CES, Vegas, General Motors with Powermat announced the wireless charging mat accessory for car interior. 2011 Chevy Volt be the first to have this mat, the rest will be followed at 2012 models of GM.
The working of this wireless charging mat is very simple, just lay your phones and MP3 players on the center console and have them wirelessly charge.
As in the deal, GM Ventures has invested $5 million in Powermat.
The other companies which have wireless charging Tech are Fujitsu, Palm, Pure Energy Solutions, ElectroHub, Green Plug and WiiPower.
Wireless charging mats generally work by first using a receiver somewhere on a portable device that magnetically connects it to a charge point on a mat that is plugged in to an electricity source.
Once fully charged that receiver sends a signal to the mat, which then halts further electricity from passing through to the device. In addition to the convenience of no wires, charging mats offer an energy-efficient alternative to chargers, which often continue to suck down electricity even after a device is fully charged.
