Abstract
This disclosure provides systems, methods and apparatuses for wireless power transmission and reception. A wireless power transmission apparatus may include a primary coil that transmits power to a corresponding secondary coil in a wireless power reception apparatus. The wireless power transmission apparatus may configure characteristics of the wireless power transmission based on a load setting of a wireless power reception apparatus. The wireless power transmission apparatus may take into account a coupling factor and power transfer characteristics of the wireless power reception apparatus in determining a configuration of the wireless power transmission from the wireless power transmission apparatus to the wireless power reception apparatus. In some implementations, a change in wireless power transmission may occur based on a corresponding change in the load. For example, the change in wireless power transmission and the corresponding change in the load may occur in relation to a synchronization event.
