1. A power transmission device, comprising:

  • a communication unit configured to;

    transmit a power capability information transmission request via a communication channel;

    receive power capability information based on the power capability information transmission request;

    a processing unit configured to;

    set a parameter based on the received power capability information,wherein the power capability information indicates a transmission type and a first parameter type;

    calculate a plurality of power transmission efficiencies for each of a plurality of parameters of the first parameter type; and

    set a first standard range of efficiency for transmission of power based on a maximum power transmission efficiency of the plurality of power transmission efficiencies; and

    a power transmission unit configured to wirelessly transmit the power based on the parameter,wherein the transmission of the power capability information transmission request occurs prior to the transmission of the power.
