CHARGING CONTROL SYSTEM, CHARGING CONTROL METHOD AND PROGRAM

A charging control system includes a flattened charging speed calculation unit (15) 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 (19) 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 (20) that controls the charging of the EVs on the basis of the charging speed calculated by the charging speed calculation unit (19).
