end plates coupled to first and second side end portions of the cell module assembly; and first and second support plates coupled to a top portion and a bottom portion of the cell module assembly and first and second side end portions of the end plates to bring the cell modules in contact with each other, wherein the cell modules each have a terminal on a first side for electrical connection between the cell modules and a fastening portion on a second side for coupling to the first and second support plates, wherein the cell modules are stacked such that the terminals and the fastening portions of the cell modules are alternately disposed in the cell module assembly in groupings of at least two terminals and fastening portions, wherein the first support plate that is coupled to the top portion of the cell module assembly and the first and second side end portions of the end plates, has a plurality of protrusions formed toward the fastening portions of the cell modules, and wherein the fastening portions of the cell modules are fastened to the protrusions. ### Claim 2 (depends on 1) The battery pack structure of claim 1, further including bus bars electrically connecting the terminals of the cell modules facing each other. ### Claim 3 (depends on 1) The battery pack structure of claim 1, wherein the first and second support plates each have locking structure at first and second side end portions, so that the support plates are locked to the end plates such that the end plates press the cell module assembly. ### Claim 4 A battery pack structure of a vehicle, the structure comprising: a cell module assembly formed by stacking a plurality of cell modules; first and second end plates coupled to first and second side end portions of the cell module assembly; a first support plate being in contact with a top portion of the cell module assembly on a surface, having locking structures at first and second side end portions thereof, and locked to the first and second end plates such that the first and second end plates press the cell module assembly; and a second support plate being in contact with a bottom portion of the cell module assembly on a surface and having locking structures to be locked to the first and second end plates such that the first and second end plates press the cell module assembly, wherein the cell modules each have a terminal on a first side for electrical connection between the cell modules and a fastening portion on a second side for coupling to the first and second support plates, wherein the cell modules are disposed such that the terminals and the fastening portions of the cell modules are alternately disposed in the cell module assembly in groupings of at least two terminals and fastening portions, wherein the first support plate that is coupled to the top portion of the cell module assembly and the first and second side end portions of the end plates has a plurality of protrusions formed toward the fastening portions of the cell modules, and wherein the fastening portions of the cell modules are fastened to the protrusions. ### Claim 5 (depends on 4) The battery pack structure of claim 4, further including bus bars electrically connecting the terminals of the cell modules facing each other.
