TIME SLICING WIRELESS CHARGING

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.
