Secondary battery management device, secondary battery, and secondary battery management program

Abstract

A secondary battery management device is connected with electronic equipment using a secondary battery as a driving power supply via the Internet. The secondary battery management device acquires performance information of the secondary battery from the electronic equipment, and measures a degradation level of performance of the secondary battery during a predetermined unit period. The secondary battery management device estimates a degrading speed of the secondary battery on the basis of the degradation level. The secondary battery management device may notify a user of the electronic equipment of the replacement timing of the secondary battery, use fees of the secondary battery, and the like.

What is claimed is: 
     
         1 . A secondary battery removably mounted on electronic equipment as a driving power supply of the electronic equipment, the secondary battery comprising:
 a data storage unit; and   a data acquisition unit to acquire data from the electronic equipment and save the acquired data in the data storage unit.   
     
     
         2 . The secondary battery according to  claim 1 , wherein
 the data acquisition unit includes an equipment ID acquisition unit that acquires, as the data, an equipment ID of the electronic equipment, and saves the acquired equipment ID in the data storage unit.   
     
     
         3 . The secondary battery according to  claim 1 , wherein
 the data acquisition unit includes a use history acquiring unit that acquires, as the data, use history of the electronic equipment, and saves the use history in the data storage unit.   
     
     
         4 . The secondary battery according to  claim 1 , wherein
 the data acquisition unit includes a user information acquiring unit that acquires, as the data, user information of a user that uses the electronic equipment, and saves the acquired user information in the data storage unit.   
     
     
         5 . The secondary battery according to  claim 1 , further comprising:
 a charge/discharge control unit to control battery charge and discharge on the basis of the acquired data.   
     
     
         6 . The secondary battery according to  claim 5 , wherein
 the secondary battery includes battery cells, and   the charge/discharge control unit controls charge and discharge of the battery cells.   
     
     
         7 . The secondary battery according to  claim 1 , wherein
 the data storage unit is configured to allow an external device to read the saved data.   
     
     
         8 . The secondary battery according to  claim 1 , further comprising:
 a degradation measuring unit to calculate a degradation level of the secondary battery on the basis of the saved acquired data.   
     
     
         9 . The secondary battery according to  claim 1 , further comprising:
 a fee calculating unit to calculate a use fee of the secondary battery on the basis of the saved acquired data.   
     
     
         10 . The secondary battery according to  claim 3 , further comprising:
 an estimation unit to estimate one or more of how degradation of the secondary battery will progress, a future use fee, and replacement timing on the basis of the saved acquired use history.
