Abstract: A charging control system includes a flattened charging speed calculation unit that calculates a flattened charge speed for fully charging EVs at a constant speed according to permitted charging time for the EVs and the amount of charging required by the EVs; a charging speed calculation unit that calculates a charging speed for the EVs by multiplying the flattened charging speed by a request demand ratio function based on change over time in electric power demand requested from the electric power supply side; and a control unit that controls the charging of the EVs on the basis of the charging speed calculated by the charging speed calculation unit.

Abstract: A charging control system that controls charging of a plurality of vehicles that run on electricity includes: an assignment unit that assigns an order of priority relating to charging to the plurality of vehicles based on a predetermined index; a receiving unit that receives electric power demands that are requested from an electric power supply side; and a control unit that selects from among the plurality of vehicles in the order of highest priority charging-object vehicles in which the ON/OFF setting for turning charging ON and OFF is to be set to ON, and sets the ON/OFF setting of charging-object vehicles to the ON setting. The control unit changes the number of charging-object vehicles in response to changes in electric power demands over time.

Abstract: A charging control system that controls charging of an automobile that uses electric power as motive power include a receiving unit that receives electric power demands from an electric power supplier side; and a control unit that controls charging on and off of the automobile. The control unit changes a ratio of a charging-on duration and a charging-off duration in each duration in allowable charging durations for the automobile according to changes of the electric power demands over time.

Abstract: A charging controller (300) controls charging of a battery by an interface device (400-1 to 400-m) on the basis of distribution system connection time when the interface device (400-1 to 400-m) and a battery mounted on EV (500-1 to 500-n) are connected to each other and on the basis of distribution system disconnection time when they are disconnected in each of the interface devices (400-1 to 400-m).
