Abstract: Each wireless charging device of the wireless charging system has a Bluetooth module for detecting signal strength between the wireless charging device and an electronic device. The signal strength information is shared among the wireless charging devices by their data transceiver units. An analysis module of each wireless charging device automatically determines one wireless charging device having the best connection, and a decision module of the determined wireless charging device transmits a charging permit to the electronic device. Cross connection of the electronic device to multiple wireless charging devices is therefore avoided.

Abstract: The wireless charging system includes a base member for placing a to-be-charged device, a wireless power transmission module for wireless charging the to-be-charged device through a magnetic resonance unit, an impedance detection module, a power throttle module, an information reception module. Through the wireless charging system, firstly, the to-be-charged device is wireless charged on the base member. Secondly, when the to-be-charged device is not a desired object and reveals a higher impedance value, the impedance detection module would detects this and inhibits/throttles the wireless power transmission module. Thirdly, if the to-be-charged object is a desired one but attached with some metallic object such as a metallic back cover, the wireless charging system may continue wireless charging according to the impedance information from the wireless reception module.
