1. A method for wireless power transmission, the method comprising:

  • scanning, using a wireless communication component of a transmitter, for available receivers within a vehicle that are authorized to receive wirelessly delivered power from the transmitter;

    detecting, by the transmitter, a first receiver and a second receiver of the available receivers within the vehicle based on the scanning;

    while continuing to scan for available receivers within the vehicle;

    receiving, by a connector of the transmitter, where the connector is coupled to a power source of the vehicle, electrical current from the power source that is used by the transmitter to generate a plurality of power waves;

    transmitting, by a plurality of antennas of the transmitter, a first set of the plurality of power waves, such that the first set of the plurality of power waves converge to form a first constructive interference pattern in proximity to a location of the first receiver within the vehicle;

    receiving, by the wireless communication component of the transmitter, a charging request from the second receiver within the vehicle, wherein the charging request;

    (i) corresponds to a request for wirelessly delivered power from the transmitter, and(ii) is sent by the second receiver when a charge level of the second receiver is less than a minimum level of charge; and

    adjusting, by a controller of the transmitter, respective gains and phases of at least a second set of the plurality of power waves, andtransmitting the second set of the plurality of power waves such that the second set of the plurality of power waves converge to form a second constructive interference pattern, distinct from the first constructive interference pattern, in proximity to a location of the second receiver within the vehicle.
