Middle or large-sized battery module
First Claim
1. A middle- or large-sized battery module comprising:
- a battery cell stack including a plurality of unit modules electrically connected with each other, wherein each unit module includes two or more battery cells constructed in a stacked structure in which electrode terminals of the battery cells are electrically connected with each other and electrode terminal connections are bent such that the battery cells are stacked;
a first module case configured to surround a side end of the battery cell stack and to partially surround upper and lower ends of the battery cell stack, the first module case being provided at a front part thereof with external input and output terminals;
a second module case coupled with the first module case, the second module case configured to surround another side end of the battery cell stack and to partially surround the upper and lower ends of the battery cell stack, the second module case being provided at a front part thereof with bus bars for connecting electrode terminals of the battery cell stack to the external input and output terminals; and
a sensing member mounted to the first module case or the second module case,wherein the first and second module cases are provided in insides thereof with pluralities of mounting grooves in which edges of the unit modules are inserted.
