<P>PROBLEM TO BE SOLVED: To reduce effects imposed upon a battery pack by a variation in charge/discharge characteristics of each single battery of the battery pack. <P>SOLUTION: The battery pack manufacturing method involves combining a plurality of single secondary batteries to produce a battery pack, of which each secondary battery is such that the absolute value of an inclination of a charge/discharge characteristic curve showing their charge/discharge characteristics changes from a first value to a second value greater than the first value, and that, out of regions changing to a third value smaller than the second value, the absolute value has an inflection region which is a region of the second value. When single batteries are confirmed to be normal (Yes in step S101), voltages between terminals of the respective single batteries are adjusted to a prescribed value in the inflection region of the charge/discharge characteristic curve of each of them (step S103), and then the respective single batteries thus adjusted are combined into a battery pack (step S104). <P>COPYRIGHT: (C)2012,JPO&INPIT |
