Central server receives travel information on the electric vehicles and remaining charge information on rechargeable batteries from the electric vehicles, forecasts demanded power in a predetermined area, and issues a charge schedule change request to charge control devices included in the predetermined area. Charging stations change charge schedules for the rechargeable batteries mounted on the electric vehicles in accordance with the charge schedule change request. ## Claims ### Claim 1 A charging system comprising: a server device capable of communicating with an electric vehicle driven by electric power stored in a rechargeable battery; and a charge control device capable of communicating with the server device and configured to control charging of the rechargeable battery, wherein the server device comprises: a communication unit configured to receive travel information on the electric vehicle and remaining charge information on the rechargeable battery of the electric vehicle from the electric vehicle; a demand forecast unit configured to forecast demanded power in a predetermined area based on the travel information and the remaining charge information received by the communication unit; and a schedule management unit configured to issue a charge schedule change request to the charge control device included in the predetermined area based on the demanded power in the predetermined area forecasted by the demand forecast unit, and the charge control device changes a charge schedule for the rechargeable battery mounted on the electric vehicle in accordance with the charge schedule change request issued by the server device. ### Claim 2 (depends on 1) The charging system according to claim 1, wherein the schedule management unit obtains a power consumption in the predetermined area, and compares the obtained power consumption and the demanded power in the predetermined area forecasted by the demand forecast unit to calculate a degree of match, in a case where the degree of match calculated by the schedule management unit is lower than a predetermined value, the demand forecast unit re-forecasts demanded power in the predetermined area based on the travel information and the remaining charge information, and the schedule management unit issues a charge schedule change request to the charge control device included in the predetermined area based on the demanded power as a re-forecast result of the demand forecast unit. ### Claim 3 (depends on 2) The charging system according to claim 2, wherein the schedule management unit learns a process of generating the charge schedule change request in the predetermined area based on the degree of match. ### Claim 4 A server device capable of communicating with an electric vehicle driven by electric power stored in a rechargeable battery and a charge control device configured to control charging of the rechargeable battery mounted on the electric vehicle, the server device comprising: a communication unit configured to receive travel information on the electric vehicle and remaining charge information on the rechargeable battery of the electric vehicle from the electric vehicle;
