PROBLEM TO BE SOLVED: To provide a battery pack module achieving reduced cost and simplification and also capable of flexibly coordinating with a desired specification.SOLUTION: A battery pack module of an embodiment includes a plurality of battery cells, a coupling bus bar and an output bus bar. The coupling bus bar electrically connects the battery cells to each other. The output bus bar is fixed to an electrode terminal of the battery cells while a first end part of the coupling bus bar is connected to the output bus bar. The coupling bus bar is detachably coupled with respect to the output bus bar such that the direction of a second end part with respect to the first end part can be changed. |
