Claim:
1. A charge control device that controls charging of a plurality of vehicles, which use electric power as a drive source, using electric power from an electric power grid, comprising: a storage unit that stores a first period in a charge control period for which the charging is controlled; a second period other than the first period in the charge control period; and a target level of a charge demand in the first period; a receipt unit that receives from each of the plurality of vehicles a required charge amount; a control unit that controls the charging using as a target the target level of the charge demand in the first period, sets up a target level of charging in the second period based on a remaining total amount that is generated by subtracting the charge amount in the first period from a total amount of the plurality of required charge amounts, and controls the charging using as a target the target level of the charging, and an assignment unit that assigns charge priorities to the plurality of vehicles based on a predetermined condition comprising a factor calculated by the formula [Required charge amount/(Remaining charge time×Charge electric power)], wherein the assignment unit assigns a higher charge priority to a vehicle having a larger factor.
