    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, andan 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.
