Abstract: This disclosure provides systems, methods, and apparatuses for wireless power transmission. Various implementations of this disclosure relate generally to intermittent wireless charging. A wireless power transmission apparatus (such as a charging pad or surface) can intermittently provide wireless power to one or more wireless power reception apparatuses based on time slices. The wireless power reception apparatuses can cool during time slices in which wireless power is not transferred. A power control unit of the wireless power transmission apparatus may determine first time slices during which wireless power will be provided to the wireless power reception apparatus. The power control unit also may determine second time slices during which wireless power will not be provided to the wireless power reception apparatus, where the second time slices are interspersed with the first time slices allowing time for thermal loads that accumulated during the first time slices to dissipate.

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.
