Patent ID: 11611229

Abstract:
Inductive charging techniques utilize a plurality of transmitter coils arranged in a predetermined configuration and each being configured to, when active, inductively transfer power to a receiver coil of a wireless device and a controller configured to control a charging session during which power is inductively transferred from at least one of the plurality of transmitter coils to the receiver coil of the wireless device, including monitoring electrical parameters of at least two transmitter coils of the plurality of transmitter coils, wherein the at least two monitored transmitter coils comprise at least one active transmitter coil, based on the monitoring, determining a position of the receiver coil relative to the plurality of transmitter coils, and selectively activating and/or deactivating at least one of the plurality of transmitter coils based on the monitoring when the position of the receiver coil changes to provide uninterrupted inductive power transfer.
