A power control system comprises a power accumulating system including a storage cell charged with electric power supplied from a power generating system and supplying a vehicle with electric power, and a control device controlling a cumulative power amount that is an amount of electric power accumulated in the storage cell. The power control system accepts drive schedule data representing whether or not the vehicle is to be used during a predetermined period. The power control system charges the storage cell till the cumulative power stored in the storage cell reaches a first threshold when the drive schedule data represents the vehicle is to be used during the period, or otherwise, it charges the storage cell till the cumulative power stored in the storage cell reaches a second threshold smaller than the first threshold when the drive schedule data represents the vehicle is not to be used during the period.

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

A battery charging system includes: an electric vehicle; a network termination unit connectable to the electric vehicle through a power line cable for supplying electric power to the electric vehicle; and a first server that transmits a control signal indicative of permission or forbiddance of power supply from the network termination unit to the electric vehicle to the electric vehicle through the network termination unit. The electric vehicle transmits identification information for identifying the electric vehicle and the user thereof to the first server through the network termination unit. The network termination unit transmits position information concerning the position of the network termination unit to the first server. The first server determines permission or forbiddance of the power supply based on the identification information and the position information.
