1. A charging control system that controls charging to vehicles that run on electric power comprising:

  • a flattened charging speed calculation unit that calculates a flattened charging speed for fully charging the vehicles at a fixed speed according to a permitted charging time for said vehicles and an amount of charging that is required by said vehicles;

    a charging speed calculation unit that calculates charging speed for the vehicles by multiplying a request demand ratio function that is based on change over time of electric power demand that is requested from the electric power supply side and said flattened charging speed together;

    a control unit that controls charging of the vehicles based on the charging speed that was calculated in said charging speed calculation unit; and

    a request demand ratio function calculation unit that calculates said request demand ratio function based on change over time of electric power demand requested from the electric power supply side;

    wherein;

    said request demand ratio function calculation unit normalizes said request demand ratio function such that the average value within said permitted charging time is “

    1”

    ; and

    said charging speed calculation unit calculates the charging speed for the vehicles by multiplying the request demand ratio function that was normalized and said flattened charging speed.
