Abstract
A battery module includes a plurality of cylindrical battery cells having electrode terminals; a module housing having an inner space to accommodate the cylindrical battery cells; and a module bus bar configured to electrically connect the cylindrical battery cells to each other. The module bus bar includes a first metal plate having a first body portion facing an outer surface of the module housing and a first contact portion configured to contact the electrode terminal; and a second metal plate having a second body portion stacked on an outer side of the first body portion of the first metal plate, a second contact portion configured to contact the electrode terminal, and a fuse portion configured to electrically connect the second contact portion and the second body portion and be disconnected at a predetermined current or above. The second metal plate has a smaller thickness than the first metal plate.
