<p><P>PROBLEM TO BE SOLVED: To suppress an operation cost by successively optimizing charging capacity used for charging an onboard storage battery of an electric vehicle. <P>SOLUTION: A charge control device 10 which controls charging of an additional storage battery 30 used when charging an onboard storage battery 62 of an electric vehicle 60 stores an electricity bill on the basis of time in a predetermined time range, calculates charge frequency necessary from specified time to time at which the predetermined time range ends when the electricity bill of the specified time in the predetermined time range is not the lowest, calculates a charge stop capacity which is a capacity of stopping charging of the additional storage battery 30 and a charge start capacity which is a capacity of starting charging of the additional storage battery 30 on the basis of the calculated charge frequency and an average charge capacity per one charging, starts charging of the additional storage battery 30 when a capacity stored in the additional storage battery 30 is less than the charge start capacity and stops charging of the additional storage battery 30 when the capacity stored in the additional storage battery 30 reaches the charge stop capacity. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
