PROBLEM TO BE SOLVED: To provide manufacturing method and manufacturing device of battery pack capable of fastening a nut to a terminal bolt reliably, even if there is a variation in the interval of terminal bolts.SOLUTION: A controller 9 prestoring a correction amount D calculates the pitch C of terminal bolts 1c, 1c, ... when splitting evenly by the number n of battery cells 1a, 1a, ..., according to mathematical formula 1, from the overall length L of a battery pack 1 in the lamination direction, the distance A to the position of axis of a terminal bolt 1c arranged on the most one end side, the distance B to the position of axis of a terminal bolt 1c arranged on the most the other end side, and the number n of battery cells 1a, 1a, ..., and also calculates the distance Xfrom one end of the battery pack 1 to the position of axis of the n-th terminal bolt 1c from one end of the battery pack 1 according to mathematical formula 2, and positions a nut runner 6 at the terminal bolt 1c by moving the battery pack 1 horizontally based on the distance Xthus calculated. |
