1. A storage battery management system, comprising:

  • a power receiving unit configured to receive power generated by a plurality of power generating units via a power system;

    a power information acquiring unit configured to acquire first system power information showing a proportion of power generated by each power generating unit in a first period;

    an intensity database configured to store environmental loading intensities indicating each an amount of environmental load emitted by each power generating unit per unit electric energy;

    a charge load intensity calculator configured to calculate a charge load intensity which is a weighted sum of the environmental loading intensities corresponding to each power generating unit by the proportion of each power generating unit shown in the first system power information;

    a storage unit configured to be capable of charging/discharging power;

    a charge/discharge judging unit configured to determine to charge the storage unit in the first period when the charge load intensity is less than a reference value, and to determine not to charge the storage unit in the first period when the charge load intensity is equal to or greater than the reference value; and

    a charge/discharge controller configured to charge the storage unit in the first period by using the power received by the power receiving unit, when the charge/discharge judging unit determines to charge the storage unit.
