Abstract
This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for wireless power transmission. In accordance with this disclosure, a wireless power transmission apparatus (such as a charging pad) may support positional freedom such that a wireless power receiving apparatus may be charged regardless of positioning or orientation of the wireless power receiving apparatus. Various implementations include the use of multiple primary coils in a wireless power transmission apparatus. In some implementations, a wireless power transmission apparatus having multiple local controllers to activate different primary coils. In some implementations, the wireless power transmission apparatus may support concurrent charging of multiple wireless power receiving apparatuses. Furthermore, in some implementations, the wireless power transmission apparatus may support charging of a wireless power receiving apparatus that moves in relation to the wireless power transmission apparatus.
