eCoupled is a proprietary near-field wireless energy transfer technology developed by Fulton Innovation, a division of Alticor. It provides wireless power transfer via inductive coupling between a primary transmission coil and a secondary receiving coil. A single primary coil can provide power to multiple secondary coils at the same time.
eCoupled technology uses its wireless data transfer and authentication capabilities to automatically identify compatible products that need to be charged, the products' charge states, and the most efficient level at which to power the device(s) in question. It also stops power transmission when the device with the receiving electricity is turned off or fully charged. Power can be transferred at up to 98 percent efficiency. eCoupled is designed to provide wireless power transfer for products ranging from low-power devices such as cell phones and media players to laptop computers and power tools. Fulton Innovation has over 220 patents filed and pending on the eCoupled system.
