The Wireless Power Consortium who’s members include Nokia, RIM, HTC, Samsung and LG have finalised the Qi charging standard.
The standard has been designed to allow consumers to easily identify compatible chargers and components. The current specification is limited to 5 Watts, but is enough to be able to charge USB-charging Symbian-powered phones.
The 5W specification is open enough to allow a number of different charging solutions. Including magnetically aligned coil that is used for the Palm Pre’s Touchstone charger, or an array of coils activated individually depending on device placement.
Gadgets and mobile devices that want to comply with the standard will have to pass third-party certification before the manufacturer is allowed to use the ‘Qi’ logo on the device or any of its packaging.
“Our customers will see the Qi logo and know: this product works with my other Qi products,”
“Publishing a standard is not enough. Without test documentation, certification services, and a logo license agreement, interoperability is an illusion.”
Wrote Menno Treffers, a senior director of standardisation at Philips who works with the consortium.
