Inductive charging (also known as wireless charging or cordless charging) uses an electromagnetic field to transfer energy between two objects through electromagnetic induction. This is usually done with a charging station. Energy is sent through an inductive coupling to an electrical device, which can then use that energy to charge batteries or run the device.
Power Matters Alliance (PMA) is a global, not-for-profit, industry organization whose mission is to advance a suite of standards and protocols for wireless power transfer. Founded by Procter & Gamble and Powermat Technologies in March 2012, PMA is networking technology companies in order to guarantee consumers interoperable devices which employ wireless power technology.
Qi (pronounced ; IPA: /tʃiː/, from the Chinese word " natural energy") is an open interface standard developed by the Wireless Power Consortium for inductive charging over distances of up to 4 cm (1.6 inches). The system uses a charging pad and a compatible device, which is placed on top of the pad, charging via resonant inductive coupling.
The most popular form of wireless power charging.
Wireless Charging provides a convenient, safe, and reliable way to charge and power millions of electrical devices at home, in the workplace and in industry. By eliminating the use of physical connectors and cables, wireless charging provides a number of efficiency, cost and safety advantages over the traditional charging cable.
A great diagram that explains how the wireless charging coils work.
Wireless charging is very convenient and it makes life easier. How exactly does it work? Join Trace as he explains the physics of wireless charging.
