Battery pack with enhanced structure for preventing short circuit and shock

摘要

The battery pack according to the present invention includes battery cells each having an electrode terminal formed at an upper and a lower portion thereof, and a cell housing for accommodating the battery cells so that only the electrode terminal is exposed to the outside, and a plurality of cells arranged in the front-rear direction. Cell assembly; A first metal plate mounted on an upper end of the cell housing and integrally contacting upper electrode terminals of the battery cells; And a second metal plate mounted on a lower end of the cell housing and integrally contacting lower electrode terminals of the battery cells, wherein the cell housing includes a portion of the first metal plate and a portion of the second metal plate. It includes a side portion having a slit that is bent to form a gap that can be inserted in each of the vertical directions and a side portion having a through hole formed in a direction crossing the slit, and a first metal plate mounted on any one of the cell housings is adjacent to each other. The second metal plate mounted on the other cell housing may be disposed to overlap within the through hole.
