PROBLEM TO BE SOLVED: To provide a manufacturing method of an on-vehicle battery pack which improves time efficiency (reduces the waste of a manufacturing time) and is capable of reducing cost of manufacture.SOLUTION: After an assembly step (step S1) and before an initial charge step (step S3), the manufacturing method includes the step of preparing a plurality of batteries 100 each of which has finished the assembly step, arranging the batteries 100 in one or more lines to form one or more battery lines 10, using an on-vehicle constraining component 20 to provide a constraint state by applying a compression load while holding the battery lines 10 between both end sides, and forming an on-vehicle battery pack 1 (step S2). All the initial charge step (step S3), an aging step (step S4) and inspection steps (steps S5-S7) are performed on the on-vehicle battery pack 1.SELECTED DRAWING: Figure 7 |
