Abstract

A wireless charging system (transmitter) has multiple transmit coils that allows for multiple receiver devices (receivers), such as cell phones, to be charged simultaneously. The receivers send data packets that include a receiver ID to the transmitter so that one of the transmitter coils can be paired with a respective one of the receivers. The transmitter can then distinguish between the communications with the receivers using the IDs such that communications with receivers connected with adjacent ones of the transmitter coils do not interfere with each other.
