Battery assembly module

A battery assembly module comprising:

• an upper cover including first coupling holes defined at a plurality of locations of the upper cover;
• a lower cover disposed to correspond to the upper cover, the lower cover including second coupling holes defined at a plurality of locations of the lower cover;
• a plurality of pouch cells, to each of which first and second electrodes are connected to a first side and a second side of the corresponding pouch cell, respectively, the plurality of pouch cells configured to selectively store and supply electricity;
• a plurality of cartridges alternately and vertically male-female-coupled, stacked between the upper cover and the lower cover, the plurality of cartridges having different shapes to accommodate the plurality of pouch cells;
• and
• a plurality of caulking pipes extending through the corresponding first and second coupling holes disposed at the plurality of locations in the upper cover and the corresponding lower cover, respectively, the plurality of caulking pipes vertically passing through some of the plurality of cartridges to be coupled to the upper cover and the lower cover,
• wherein the plurality of cartridges include first cartridges and second cartridges, and
• wherein first electrode and second electrode have shapes bent upward and downward, respectively, in opposite directions, such that first electrode of one pouch cell and second electrode of another pouch cell disposed below the one pouch cell are configured to, when assembled, surround a voltage sensing busbar of a first cartridge that is disposed between the one pouch cell and the another pouch cell.
