Patent ID: 8749202

Claim:
A battery control system comprising: a power generation unit that generates electric power from renewable energy as an energy source; a battery for 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 an amount of electric power consumption to be consumed based on information input by a user corresponding to the amount of electric power consumption to be consumed and based on a variance value calculated from previously accumulated actual measured electric power consumption values corresponding to the information input by the user; a determination unit that determines 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.
