Charging control system, charging control method, and recording medium
First Claim
1. A charging control system that controls charging of a plurality of vehicles that run on electric power, the charging control system comprising:
- an assignment unit that, based on a predetermined index, assigns to said plurality of vehicles an order of priority relating to charging;
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 said plurality of vehicles, in higher orders according to order of said order of priority, charging-object vehicles in which an ON/OFF setting for ON/OFF of said charging is to be set to ON and sets the ON/OFF setting of said charging-object vehicles to ON,wherein said control unit changes a number of said charging-object vehicles according to changes of said electric power demands over time,wherein said assignment unit uses, as said predetermined index, an index that is based on at least one of a charging amount of said vehicles, a charging rate of said vehicles, a permissible range of charging amount of said vehicles, a permissible range of charging rate of said vehicles, a desired charging amount that is necessary for said vehicles, a desired charging speed that is necessary for said vehicles, a permissible charging speed of said vehicles, a time interval required for said desired charging amount in said vehicles, and a time interval in which charging of said vehicles is possible, andwherein said assignment unit uses, as said predetermined index, an index that is based on a value that is calculated by a formula;
(said desired charging amount, said desired charging rate, or said time interval required for said desired charging)/(said time interval in which said charging is possible).

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.

11. A charging control method in a charging control system that controls charging of a plurality of vehicles that run on electric power, the charging control method comprising:
-
based on a predetermined index, assigning to said plurality of vehicles an order of priority relating to charging; receiving electric power demands that are requested from an electric power supply side; and selecting from among said plurality of vehicles in higher orders according to order of said order of priority charging-object vehicles in which an ON/OFF setting relating to ON/OFF of said charging is to be set to ON and implementing a control procedure to set the ON/OFF setting of said charging-object vehicles to ON, wherein, in said control procedure, a number of said charging-object vehicles changes according to changes of said electric power demands over time, wherein, in said assigning to said plurality of vehicles, as said predetermined index, an index is used that is based on at least one of a charging amount of said vehicles, a charging rate of said vehicles, a permissible range of charging amount of said vehicles, a permissible range of charging rate of said vehicles, a desired charging amount that is necessary for said vehicles, a desired charging speed that is necessary for said vehicles, a permissible charging speed of said vehicles, a time interval required for said desired charging amount in said vehicles, and a time interval in which charging of said vehicles is possible, and wherein, in said assigning to said plurality of vehicles, as said predetermined index, an index that is used based on a value that is calculated by a formula; (said desired charging amount, said desired charging rate, or said time interval required for said desired charging)/(said time interval in which said charging is possible). - View Dependent Claims (12, 13, 14)

15. A non-transitory recording medium that can be read by a computer and on which a program is recorded that causes the computer for controlling charging of a plurality of vehicles that run on electric power to execute:
-
an assignment procedure of based on a predetermined index, assigning an order of priority relating to charging to said plurality of vehicles; a reception procedure of receiving electric power demands that are requested from an electric power supply side; and a control procedure of selecting from among said plurality of vehicles according to higher orders of said order of priority charging-object vehicles in which an ON/OFF setting for ON/OFF of said charging is to be set to ON and implementing a control procedure to set the ON/OFF setting of said charging-object vehicles to ON, wherein, in said control procedure, a number of said charging-object vehicles changes according to changes of said electric power demands over time, wherein, in said assignment procedure, as said predetermined index, an index is used that is based on at least one of a charging amount of said vehicles, a charging rate of said vehicles, a permissible range of charging amount of said vehicles, a permissible range of charging rate of said vehicles, a desired charging amount that is necessary for said vehicles, a desired charging speed that is necessary for said vehicles, a permissible charging speed of said vehicles, a time interval required for said desired charging amount in said vehicles, and a time interval in which charging of said vehicles is possible, and wherein, in said assignment procedure, as said predetermined index, an index that is used based on a value that is calculated by a formula; (said desired charging amount, said desired charging rate, or said time interval required for said desired charging)/(said time interval in which said charging is possible). - View Dependent Claims (16, 17, 18)
