A battery history information management device (100) for managing history information of a secondary battery (200) includes: a connection determination unit (110) which determines whether a charge/discharge device connected to the secondary battery (200) is (i) a first charge/discharge device (20) connected via a communication network (30) to a server (40) which manages the history information or (ii) a second charge/discharge device (50) not connected to the server (40); a battery history recording unit (120) which records, when it is determined that the charge/discharge device is the second charge/discharge device (50), charge/discharge history for second charge/discharge device (50) into battery history data (191); and a history upload control unit (130) which transmits, when it is determined that the charge/discharge device is the first charge/discharge device (20), the battery history data (191) to the server (40) via the first charge/discharge device (20).
