Abstract
Disclosed herein is a battery module for medium- or large-sized battery packs, including a plurality of unit cells, wherein the unit cells are generally plate-shaped unit cells, and the unit cells are electrically connected with each other while the unit cells are arranged in a module case so as to constitute at least two rows and at least two columns. According to the present invention, integration of the battery module is highly improved. Especially, the vertical-direction mechanical strength of the battery module is further increased, and the number of connecting members necessary for the electrical connection between the unit cells is reduced.
