The present invention relates to a battery pack which is formed by stacking multiple battery cells or battery modules side by side. The battery cell of the present invention is capable of cooling each battery cell or battery module evenly by properly closing up cooling channels formed between the battery cells, the battery modules, or battery cells included in the battery modules according to a pressure difference between an inflow of cooling air and an outflow of the cooling air and the shapes of the battery packs to improve distribution uniformity in a flux of the cooling air. As battery cells or battery modules of the battery pack can be evenly cooled down, the performance and life of the battery pack can be improved. |
