Power supply system for house

A house to which electrical power is supplied from an electric vehicle, the house comprising:

• 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 receives, from the electric vehicle, a delay time taking a power transmission delay into account;
• and
• a power prediction device that is constructed such that it predicts electrical power that will need to be supplied from the electric vehicle to the house in the delay time, and
• communicates a prediction data of the predicted electrical power to the electrical vehicle via the house communication device,
• 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 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, and
• the vehicle communication device is constructed such that it communicates the stored delay time to the house communication device.

An electric vehicle which supplies electrical power to a house, the electric vehicle comprising:

• 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,
• wherein the power supply control device stores a delay time that has been determined in advance by at least one of actual measurement and calculation, the delay time taking a power transmission delay into account,
• the vehicle communication device is constructed such that it communicates the stored delay time to the house,
• the vehicle communication device receives a prediction data of predicted electrical power which will need to be supplied from the electric vehicle to the house in the delay time, and
• the power supply control device is constructed such that it supplies electrical power that corresponds to the prediction data to the power-supplying coil, and
• wherein the delay time is a time from when the prediction data is output by a power prediction device, which predicts electrical power required in the house, of the house to when electrical power that corresponds to the prediction data is supplied to the house,
• 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, and
• the vehicle communication device is constructed such that it communicates the stored delay time to the house communication device.
