STACKED TYPE BATTERY MODULE HAVING EASILY MODIFIABLE CONNECTION STRUCTURE

摘要

Disclosed herein is a battery module including unit cells, each of which has electrode terminals formed at one side thereof, cartridges for fixing the unit cells, respectively, and busbars coupled to the electrode terminals for electrically interconnecting the unit cells, wherein the unit cells are mounted at the respective cartridges such that the electrode terminals are opposite to each other, and the electrode terminals are connected in parallel to each other via the busbars for parallel connection, which are mounted at the respective cartridges, such that the cartridges have unit cell parallel connection structures, and wherein the cartridges are stacked such that the unit cell parallel connection structures are arranged in a height direction from a ground, and the unit cell parallel connection structures are connected to each other via a series connection member and/or a parallel connection member for connecting the unit cell parallel connection structures in series and/or in parallel to each other.
