Provided is an information processing device capable of easily determining the number of times of charge/discharge of each of a plurality of secondary battery packs, the information processing device including a charge/discharge execution unit (21, 22, 23) having the following configuration. That is, the charge/discharge execution unit (21, 22, 23) determines the number of times of charge/discharge of each of a plurality of secondary battery packs (11, 12, 13) based on: the number of times a fully-charged state of the secondary battery pack is detected when the charge to the secondary battery pack is executed; the number of times an intermediate state in which the remaining capacity of the secondary battery pack becomes equal to a predetermined value between the maximum remaining capacity value in the fully-charged state and a remaining capacity of zero is detected when the discharge from the secondary battery pack is executed; and the number of times a remaining capacity near-zero state in which the remaining capacity of the secondary battery pack becomes equal to a near-zero value closer to the remaining capacity of zero than the predetermined value is detected when the discharge from the secondary battery pack is executed.
