1. A method, comprising:

  • determining, by a base station comprising a plurality of transmitting coils, a first plurality of mutual magnetic parameters, each mutual magnetic parameter of the first plurality of mutual magnetic parameters being associated with a transmitting coil of the plurality of transmitting coils and a receiving coil of at least one receiving coil associated with at least one electronic device remotely located from and to be remotely charged by the base station;

    determining, by the base station, a plurality of control signals based on the first plurality of mutual magnetic parameters, each control signal of the plurality of control signals being associated with a corresponding transmitting coil of the plurality of transmitting coils;

    providing each control signal of the plurality of control signals to a driving circuit coupled to the control signal'"'"'s corresponding transmitting coil; and

    using each control signal of the plurality of control signals to cause the driving circuit coupled to the control signal'"'"'s corresponding transmitting coil to cause a current with a magnitude and phase determined from the control signal to flow in the corresponding transmitting coil.
