Charge control device, charge system, charge control method, and program

A charge control device configured to control a plurality of charge facilities, the plurality of charge facilities each being electrically connectable to an electrically driven vehicle on which a storage battery is mounted, the plurality of charge facilities each being configured to supply a charging current to the storage battery of the electrically driven vehicle, which is electrically connected, within a range not exceeding a charging current value allocated by the charge control device, the charge control device comprising:

• a communicator configured to communicate with each of the plurality of charge facilities;
• a determiner configured to determine the charging current value to be allocated to each of the plurality of charge facilities;
• and
• a controller configured to cause the communicator to transmit the charging current value determined by the determiner to each of the plurality of charge facilities,
• the determiner being configured to
• make an allocation of one or more first current values respectively to one or more charge facilities which are included in the plurality of charge facilities and each of which is not supplying the charging current,
• make an allocation of one or more second current values respectively to one or more charge facilities which are included in the plurality of charge facilities and each of which is supplying the charging current, and
• determine the allocation of the one or more first current values and the allocation of the one or more second current values such that a total of the one or more first current values and the one or more second current values does not exceed an upper limit value which is predetermined.
