Charging control apparatus

A charging control apparatus, comprising:

• a communication unit that communicates between the vehicle and a server apparatus that includes a geographic data base that stores geographic data, a route calculation unit that calculates a scheduled travel route to a destination based on geographic data read from the geographic data base and a vehicle position, and a required charge amount calculation unit that calculates a required charge amount for the vehicle to travel the corresponding scheduled travel route, based on a travel distance of the scheduled travel route calculated by the route calculation unit and a power consumption amount of the battery installed in the corresponding vehicle per unit travel distance of the vehicle;
• an electric fee table in which data indicating a change of an electric fee with the elapse of time of a system power is set;
• and
• a charging schedule processing unit that acquires from the vehicle a residual capacity of the battery installed in the vehicle via the communication unit, acquires the required charge amount for the vehicle to travel the scheduled travel route from the server unit, plans a charging schedule to charge the battery installed in the vehicle from the residual capacity of the battery to the required charge amount at the cheapest electric fee by at predetermined date and time, based on the electric fee table, and causes a charging/discharging unit that charges the battery with the system power to supply the system power to the battery in accordance with the corresponding charging schedule.
