METHOD AND SYSTEM FOR SIMULTANEOUSLY WIRELESSLY CHARGING PORTABLE RECHARGEABLE DEVICES BASED ON WIRELESS INDUCTIVE POWER TRANSFER WITH SEAMLESS FREE POSITIONING CAPABILITY

摘要

Embodiments of the present invention specifically relate to a system for seamlessly and simultaneously wirelessly charging portable chargeable devices with free positioning capability and a method therefor. The system comprises a charging subsystem. The charging subsystem comprises an electromagnetic shield for minimization of interference, and a transmitter coil array. The transmitter coil array comprises a first plurality of transmitter coils juxtaposed to each other and coupled to the electromagnetic shield, and a second plurality of transmitter coils, wherein each of the second plurality of transmitter coils is overlappingly coupled to at least a pair of the first plurality of transmitter coils in juxtaposition and positioned thereunder, and at least a controller for scanning the transmitter coils and selectively activating and deactivating the transmitter coils based on the detection of receiver coils positioned at any position relative to the transmitter coils, and a portable chargeable device comprising a receiver coil, wherein the system facilitates minimization of interference between the transmitter coils in juxtaposition.
