Charging control system, charging control method, and program
First Claim
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.

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.
