Abstract: A battery pack has reduced manufacturing cost, improved heat dissipation efficiency, and enhanced product stability. The battery pack includes a cover structure including a first cover frame having a plate shape with both front and rear ends bent leftward to form an inner space and a second cover frame having a portion coupled to the first cover frame and having a plate shape with both front and rear ends bent rightward to form an inner space; a first battery module having a plurality of battery cells; and a second battery module having a plurality of battery cells.

Abstract: A battery module has improved impact resistance and safety and a battery pack including the same. The battery module includes a first case having a receiving space, a plurality of battery cells received in the receiving space in an upright state such that a positive electrode terminal of each of the battery cells faces upwards, one or more busbars located in the vicinity of the positive electrode terminals of the battery cells, a wire configured to electrically connect each of the battery cells and a corresponding one of the busbars to each other, a rib structure located above the battery cells, the rib structure being provided with an upwardly protruding rib configured to protect the wire and an opening configured to allow the wire to extend therethrough, and a resin layer provided above the battery cells, and a battery pack including the same.

Abstract: A battery pack includes battery modules each including secondary batteries; a connection plate having a body portion at the upper portion or the lower portion of the secondary batteries and provided with connection terminals respectively in electrical contact and connection with the electrode terminal at one of the secondary batteries, and a connection portion to protrusively extend in a left or right direction from the body portion so that a part of the protrusively extending portion is bent upward or downward from the body portion and the bent end is bonded to a portion of the other connection plate; and a module housing having hollows in which the secondary batteries are inserted and accommodated, the module housing having a separating groove at an outer wall thereof by indenting a portion of the outer wall inward to be spaced apart from the bent end of the connection portion.
