Electric power control system, electric power control method, and control device, data storage medium, and server device for the same

A control device adapted to control a cumulative power amount that is an amount of electric power accumulated in a storage cell that is charged with electric power and supplies a load with electric power,

• the control device comprising:
• a drive schedule acceptance unit for accepting drive schedule data that represents whether or not the load is to be used during a predetermined period in the future, and
• a cumulative power amount control unit for charging the storage cell with electric power till the cumulative power amount reaches a first threshold if the accepted drive schedule data represents the load is to be used during the period, or otherwise, charging the storage cell with electric power till the cumulative power amount reaches a second threshold lower than the first threshold if the drive schedule data represents the load is not to be used during the period.

A server device comprising:

• a drive schedule reception unit for receiving drive schedule data that represents whether or not a load is to be used during a predetermined period in the future, the drive schedule data being received from a control device adapted to control a cumulative power amount that is an amount of electric power accumulated in a storage cell, the storage cell being charged with electric power and supplying the load with electric power,
• a threshold cumulative power amount control unit for determining a lower limit of the cumulative power amount based on the received drive schedule data, the lower limit being a second threshold smaller than a first threshold that is an upper limit of the cumulative power amount, and
• a threshold cumulative power amount transmission unit for transmitting the determined second threshold to the control device.
