<p>PURPOSE: A unit module assembly prevents electric connection of all battery cells in a unit module with external devices and maintains electric connection among all the battery cells in case of malfunctioning such as overcharging, thereby improving safety. CONSTITUTION: A unit module assembly has two or more unit modules (100-120) in which at least two battery cells are connected to each other. An electrode terminal (20A) of one battery cell is electrically connected to a bus bar (50) or an inter bus bar, and terminals of the residual battery cells are electrically connected to the electrode terminal of the first battery cell in a state of not in contact with the bus bar or the inter bus bar.</p> |
