1. A power supply system for a house that supplies electrical power from an electric vehicle to the house, whereinthe electric vehicle comprises:

  • a rechargeable battery;

    a power-supplying coil;

    a power-supplying circuit that, using the rechargeable battery as a power source, drives the power-supplying coil in a voltage-current waveform that is suitable for supplying electrical power wirelessly;

    a vehicle communication device; and

    a power supply control device that controls the power-supplying circuit; and

    whereinthe house comprises;

    a power-receiving coil;

    a power-receiving circuit that receives electrical power from the power-receiving coil into the house;

    a house communication device that is configured to communicate with the vehicle communication device; and

    a power prediction device that predicts electrical power required in the house,the power-supplying coil and the power-receiving coil are constructed such that they form an electromagnetic coupling circuit when they are placed a preset distance apart from each other,the power prediction device is constructed such that it predicts electrical power that will need to be supplied from the electric vehicle to the house in a delay time taking a power transmission delay into account, and communicates a prediction data of the predicted electrical power to the power supply control device via the house communication device and the vehicle communication device, andthe power supply control device is constructed such that it supplies electrical power that corresponds to the power prediction data to the power-supplying coil,wherein the delay time is a time from when the prediction data is output by the power prediction device to when electrical power that corresponds to the prediction data is supplied to the house,wherein the power supply control device of the electric vehicle stores delay time that has been determined in advance by at least one of actual measurement and calculation, andthe vehicle communication device is constructed such that it communicates the stored delay time to the house communication device.
