Abstract

Provided is a battery control system including a power generation unit that generates electric power from renewable energy as an energy source, a battery storing the electric power, a power generation amount estimation unit that estimates a generation amount of electric power generated by the power generation unit, based on estimation information in which a renewable energy amount available to the power generation unit is estimated, a power consumption amount estimation unit that estimates power consumption, a determination unit that determinates whether or not electric power is to be stored in the battery, based on a storage amount of the battery, the generation amount of electric power and the amount of power consumption, and a power acquisition unit that acquires electric power to be stored in the battery, when, as a result of determination by the determination unit, electric power is to be stored in the battery.

First claim

What is claimed is:

1. A device comprising:
processing circuitry configured to
receive input information about a visitor to a building, the input information about the visitor including the schedule of the visitor and attributes of the visitor;
estimate a generation amount of electric power generated by a power generator, based on estimation information in which a renewable energy amount available to the power generator is estimated;
estimate an amount of electric power consumption to be consumed in the building based on the input information about the visitor and based on a variance value calculated from previously accumulated actual measured electric power consumption values corresponding to the input information about the visitor;
determine whether or not electric power is to be stored in a battery, based on a storage amount of the battery, the generation amount of electric power, and the amount of electric power consumption; and
upon determination that electric power is to be stored in the battery, control acquisition of additional electric power and storage of the additional electric power in the battery.

2. The device according to claim 1 , wherein
the processing circuitry is configured to calculate the variance value from an average value of the accumulated actual measured electric power consumption values.

3. The device according to claim 1 , wherein
the processing circuitry is configured to receive the input information from a mobile device.

4. The device according to claim 1 , wherein
the generation amount of electric power generated by the power generator includes electric power from sunlight energy as an energy source.

5. The device according to claim 4 , wherein
the estimation information includes an estimated solar irradiation duration and intensity.

6. The device according to claim 1 , wherein
the generation amount of electric power generated by the power generator includes electric power from wind power as an energy source.

7. The device according to claim 6 , wherein
the estimation information includes wind speed estimation information.

8. A method, comprising:
receiving input information about a visitor to a building, the input information about the visitor including the schedule of the visitor and attributes of the visitor;
estimating a generation amount of electric power generated by a power generator, based on estimation information in which an available renewable energy amount is estimated;
estimating an amount of electric power consumption to be consumed based on the input information about the visitor and based on a variance value calculated from previously accumulated actual measured electric power consumption values corresponding to the input information about the visitor;
determining whether or not electric power is to be stored in a battery, based on a storage amount of the battery, the generation amount of electric power and the amount of electric power consumption; and
upon determination that electric power is to be stored in the battery, controlling acquisition of additional electric power and storage of the additional electric power in the battery.

9. The method according to claim 8 , further comprising:
calculating the variance value from an average value of the accumulated actual measured electric power consumption values.

10. The method according to claim 8 , further comprising:
receiving the input information from a mobile device.

11. The method according to claim 8 , wherein
the generation amount of electric power generated by the power generator includes electric power from sunlight energy as an energy source.

12. The method according to claim 11 , wherein
the estimation information includes an estimated solar irradiation duration and intensity.

13. The method according to claim 8 wherein
the generation amount of electric power generated by the power generator includes electric power from wind power as an energy source.

14. The method according to claim 13 , wherein
the estimation information includes wind speed estimation information.

15. A non-transitory computer-readable recording medium having computer-readable instructions, which when executed by a computer, causes the computer to perform a method, the method comprising:
receiving input information about a visitor to a building, the input information about the visitor including the schedule of the visitor and attributes of the visitor;
estimating a generation amount of electric power generated by a power generator, based on estimation information in which an available renewable energy amount is estimated;
estimating an amount of electric power consumption to be consumed based on the input information about the visitor and based on a variance value calculated from previously accumulated actual measured electric power consumption values corresponding to the input information about the visitor;
determining whether or not electric power is to be stored in a battery, based on a storage amount of the battery, the generation amount of electric power and the amount of electric power consumption; and
upon determination that electric power is to be stored in the battery, controlling acquisition of additional electric power and storage of the additional electric power in the battery.
