1. An information processing device, comprising:

  • a plurality of secondary battery packs; and

    a charge/discharge execution unit for executing charge to the plurality of secondary battery packs and discharge from the plurality of secondary battery packs,the charge/discharge execution unit being configured to, when executing the discharge, select one of the plurality of secondary battery packs as a selected secondary battery pack based on a number of times of charge/discharge of each of the plurality of secondary battery packs, and execute the discharge from the selected secondary battery pack,wherein the charge/discharge execution unit is configured to count;

    a detection of a fully-charged state of the each of the plurality of secondary battery packs when the charge to the each of the plurality of secondary battery packs is executed, as a number of the detection of the fully-charged state;

    a detection of an intermediate state in which a remaining capacity of the each of the plurality of secondary battery packs becomes equal to a predetermined value between a maximum remaining capacity value in the fully-charged state and a remaining capacity of zero, when the discharge from the each of the plurality of secondary battery packs is executed, as a number of the detection of the intermediate state; and

    a detection of a remaining capacity near-zero state in which the remaining capacity of the each of the plurality of secondary battery packs becomes equal to a near-zero value closer to the remaining capacity of zero than the predetermined value, when the discharge from the each of the plurality of secondary battery packs is executed, as a number of the detection of the remaining capacity near-zero state; and

    the charge/discharge execution unit is configured to determine the number of times of charge/discharge of the each of the plurality of secondary battery packs based on the number of the detection of the fully-charged state, the number of the detection of the intermediate state, and the number of the detection of the remaining capacity near-zero state.
