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.
