Abstract

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

a history upload control unit configured to transmit, when it is determined that the charge/discharge device is the first charge/discharge device, the battery history data recorded with the history information to the server via the first charge/discharge device.

2. The battery history information management device according to claim 1,

wherein the history upload control unit is further configured to delete, from the battery history data stored in a storage unit, the history information recorded in the battery history data which the history upload control unit has transmitted to the server.

3. The battery history information management device according to claim 1, further comprising:

a charge/discharge threshold determination unit configured to determine whether or not a charge/discharge integrated value exceeds a predetermined threshold, the charge/discharge integrated value being an integrated value of one of the following;

the number of times of charge;

the number of times of discharge;

the number of times of charge-and-discharge;

an amount of charge;

an amount of discharge; and

an amount of charge-and-discharge, for the secondary battery, which is indicated by the charge/discharge history which is history of charge or discharge to or from the secondary battery performed by the second charge/discharge device recorded in the battery history data; and

a penalty execution unit configured to execute, when it is determined that the charge/discharge integrated value exceeds the threshold, a penalty operation including limiting charging or discharging to or from the secondary battery or issuing an alert.

4. The battery history information management device according to claim 3,

wherein, the penalty execution unit is configured to execute, when it is determined that the charge/discharge integrated value exceeds the threshold, the penalty operation at next charge or discharge to or from the secondary battery performed by the second charge/discharge device.

5. The battery history information management device according to claim 3, further comprising

an alert execution unit configured to issue an alert when a difference between the charge/discharge integrated value and the threshold is smaller than or equal to a predetermined value.

6. The battery history information management device according to claim 3,

wherein the charge/discharge threshold determination unit is configured to:

increase the threshold when the history upload control unit transmits the battery history data to the server; and

determine whether or not the charge-and-discharge integrated value exceeds the threshold increased.

7. The battery history information management device according to claim 3, further comprising:

a storage unit configured to store registered charge/discharge device data indicating a registered charge/discharge device that is the second charge/discharge device previously registered; and

a registered charge/discharge determination unit configured to determine, when it is determined that the charge/discharge device is the second charge/discharge device, whether the second charge/discharge device is the registered charge/discharge device or the unregistered charge/discharge device which is not the registered charge/discharge device, with reference to the registered charge/discharge device data,

wherein the charge/discharge threshold determination unit is configured to;
