Wireless power transmission apparatus with multiple primary coils and adjacent coil muting

A wireless power transmission apparatus, comprising:

• a plurality of primary coils that are selectively and individually capable of transmitting wireless power based on a power signal;
• a plurality of switches capable of individually coupling one or more coils of the primary coils to a driver;
• and
• a controller configured to:
• control the plurality of switches to couple ones of the plurality of primary coils to the driver at different times to enable ping actions via each primary coil or each subset of the plurality of primary coils;
• cause the driver to transmit the wireless power to a first wireless power receiving apparatus via a first primary coil based on a communication or ping response received from the first wireless power receiving apparatus while the first primary coil is coupled to the driver;
• and
• disconnect, by the plurality of switches, one or more coils that are adjacent to the first primary coil from the driver while the first primary coil is transmitting wireless power to the first wireless power receiving apparatus.

A method of a wireless power transmission apparatus, the method comprising:

• coupling, via a plurality of switches, at least a first primary coil of a plurality of primary coils to a local controller to enable a ping action via the first primary coil, the plurality of switches capable of individually coupling one or more coils of the plurality of primary coils to respective local controllers, the plurality of primary coils selectively and individually capable of transmitting wireless power;
• detecting a first wireless power receiving apparatus based on a communication or ping response from the first wireless power receiving apparatus while the first primary coil is coupled to the local controller;
• causing the local controller to transmit the wireless power to the first wireless power receiving apparatus via the first primary coil;
• transmitting wireless power to the first wireless power receiving apparatus via the first primary coil;
• and
• preventing the plurality of switches from coupling one or more adjacent primary coils to any local controller while the first primary coil is transmitting the wireless power to the first wireless power receiving apparatus.
