Abstract

An information processing system includes a controller that controls the supply route of electric power in a house, a determining unit that determines, based on the driving schedule of an electric vehicle, necessary energy with which the car battery of the electric vehicle should be charged, and a detector that detects first charge energy with which the car battery is charged. The controller selects, based on the necessary energy and the first charge energy, which one of electric power supplied from a power company and electric power supplied from the car battery is to be consumed in the house.

Claims

1. An information processing apparatus comprising:

a controller that controls a supply route of electric power in a house;

a determining unit that determines, based on a driving schedule of an electric vehicle, necessary energy with which a car battery of the electric vehicle should be charged; and

a detector that detects first charge energy with which the car battery is charged,

wherein said controller selects, based on the necessary energy and the first charge energy, which one of electric power supplied from a power company and electric power supplied from the car battery is to be consumed in the house.

2. The information processing apparatus according to claim 1, further comprising a calculator that calculates surplus energy in the car battery based on a difference between the first charge energy and the necessary energy,

wherein said controller supplies, from the car battery, electric power corresponding to the calculated surplus energy for consumption in the house.

3. The information processing apparatus according to claim 2, wherein said determining unit further determines a predicted house power consumption based on an action schedule in the house, and

when the determined predicted house power consumption is not more than a predetermined amount, said controller leaves, in the car battery, the surplus electric power based on the surplus energy.

4. The information processing apparatus according to claim 1, wherein said determining unit further determines the predicted house power consumption based on the action schedule in the house,

said detector further detects second charge energy with which a house battery provided in the house is charged, and

said controller selects, based on the predicted house power consumption and the second charge energy, whether to supply electric power with which the car battery is charged for consumption in the house or to charge the house battery.

5. The information processing apparatus according to claim 1, further comprising a notifier that notifies a user to the supply route of the electric power.

6. The information processing apparatus according to claim 1, further comprising an accumulator that accumulates a first driving record about consumption of a battery in an electric vehicle of the same model as the electric vehicle, wherein said determining unit determines the necessary energy based on the driving schedule and the accumulated first driving record.

7. The information processing apparatus according to claim 6, wherein said accumulator further accumulates a second driving record about consumption of a battery in an electric vehicle having the same driving capability as the electric vehicle, and

said determining unit determines the necessary energy based on the driving schedule and the accumulated second driving record.

8. The information processing apparatus according to claim 1, further comprising a power generation amount predictor that predicts a power generation amount of a photovoltaic power generation system provided in the house,

wherein said controller controls the supply route of the electric power in the house while selecting, based on the power generation amount, which one of the electric power supplied from the power company and the electric power supplied from the car battery of the electric vehicle is to be consumed in the house.
