Abstract
A wireless charging system is configured to charge one or more receiver devices simultaneously. The wireless charging system includes a plurality of coils for wireless charging the one or more receiver devices. The wireless charging system may use a machine learning algorithm to detect the one or more receiver devices and select which of the multiple coils to activate for charging the multiple coils. Based on measurements made from signal through the coils within the wireless charging system, the machine learning algorithm determines a subset of the coils to activate for charging the detected one or more receiver devices.
