RECONSTITUTED BATTERY PACK, METHOD FOR MANUFACTURING RECONSTITUTED BATTERY PACK, METHOD FOR USING RECONSTITUTED BATTERY PACK, AND RECONSTITUTED BATTERY PACK CONTROL SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a reconstituted battery pack preventing overcharge or over-discharge failure of a part of used secondary batteries thereof and sufficiently exhibiting performance of each used secondary battery thereof, and to provide a manufacturing method thereof, a using method thereof and a reconstituted battery pack control system.

SOLUTION: This method includes the acquiring step (step S1) of acquiring a reference time charged amount of each used secondary battery constituting the used battery pack using a first charged state controlling section having been controlling the charged state of the used battery pack when used or a second charged state controlling section attaining controlling of the charged state of each used secondary battery equal to that by the first charged state controlling section, the selecting step (step S2) of selecting a plurality of used secondary batteries having approximate reference time charged amounts from a group of the used secondary batteries of the acquired reference time charged amounts and the assembling step (step 3) of combining the plurality of used secondary batteries selected to constitute a new reconstituted battery pack.
