Abstract
A battery pack structure of a vehicle, may include a cell module assembly formed by stacking a plurality of cell modules, end plates coupled to both side end portions of the cell module assembly, and support plates coupled to the top and the bottom of the cell module assembly and both side end portions of the end plates to bring the cell modules in contact with each other.
Claims5
A battery pack structure of a vehicle, the structure comprising:
- a cell module assembly formed by stacking a plurality of cell modules;
- 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.
