Abstract
In an embodiment a charging box includes a bottom surface parallel to a first axis, a driver, a switch matrix and a plurality of transmitting coils, each of the plurality of transmitting coils being wrapped around a second axis that is orthogonal to the first axis, wherein the driver is electrically connected to the switch matrix and the plurality of transmitting coils, wherein the switch matrix is configured to determine a power distribution of the plurality of transmitting coils by transmitting a ping to a mobile device and receiving a feedback from the mobile device, to select, based on a ping and feedback process, a pair of transmitting coils that transmits the most power and connect the determined pair of transmitting coils in series, and wherein the charging box is configured to wirelessly transmit power to the mobile device via the selected transmitting coils.
