Abstract
This invention relates to a battery pack and a vehicle including the battery pack, the battery pack comprising: a plurality of cell blocks formed by stacking a plurality of battery cells; a battery pack housing for housing the cell blocks; and a transverse member disposed between adjacent cell blocks to support adjacent cell blocks, and the transverse member comprising a plurality of side beams that engage with each other, wherein each side beam includes: a protrusion projecting toward each other, and the protrusions formed at each side beam are arranged to overlap in the front-rear direction in the engaged state, thus improving the structure of the transverse member for securing and fastening the cell blocks to the battery pack housing, facilitating maintenance and effectively absorbing volume expansion due to the bulging of the battery cells and cell blocks, thereby providing excellent stability.
