Qi wireless charging standard of the Wireless Power Consortium is free in the phone is not physically connected to all, but still requires your device and wireless charging platform to be in contact with each other to work. Today, the WPC has announced that version 1.2 of the Qi standard add support for loading resonance, it is possible that your phone is charged when near a block of Qi and not directly on it.
It is a relatively minor change to the current 1.1 Qi receivers will be able to enjoy it without any additional hardware, but it opens up various opportunities for companies that want to build a Qi support in their products. The CMP said Qi chargers now be integrated into tables and desks instead of being placed on the surface, making it less boring. “The new models of low-power transmitters” will be easier to build Qi chargers in cars, and Qi Qi transmitter 1.2 can charge multiple devices simultaneously. Qi can now also provide up to 2000 watts of power for household appliances (the statement specifically mentions “kitchen appliances”).
Current Qi devices can draw power from these new transmitters at distances up to 30 mm (about 1.2 inches), while devices with built especially Qi 1,2 receptors increase the distance of 45 mm (1.8 inches). Engadget reports that the version of the Qi resonance is about 70-80 percent efficiency, while the old inductive version is about 85 percent efficiency, and Qi 1.1 and 1.2 transmitters and receivers will be able to interoperate, inductive load and buffer Nexus Wireless Charger still be able to collect 1.2 Qi phones. Just know that the resonant load required 1.2 Qi transmitter.
While Qi is just one of many wireless charging standard (also Rezence and PMA), which we hope not to have to keep track of all these competing consortia for a long time. Broadcom announced a new chip earlier this year that promises support for the three main rules. 1.2 Qi chargers should start to appear later this year and in 2015.
