Wireless power transmission apparatus with multiple controllers and adjacent coil muting

A method for transmission of wireless power comprising:

• managing a plurality of primary coils in a wireless power transmission apparatus, wherein the plurality of primary coils are independently capable of transmitting wireless power, the plurality of primary coils including at least a first primary coil and a second primary coil that are adjacent or overlapping with each other, and wherein the plurality of primary coils are managed by a corresponding plurality of local controllers, the plurality of local controllers including at least a first local controller and a second local controller for controlling the first primary coil and the second primary coil, respectively;
• determining that a first wireless power receiving apparatus is in proximity to a first primary coil;
• and
• in response to a determination that a first wireless power receiving apparatus is in proximity to the first primary coil:
• causing the first primary coil to transmit wireless power, and
• disabling the second primary coil that is adjacent or overlapping with the first primary coil while the first primary coil is transmitting the wireless power.
