The present invention relates to a battery module case, and more particularly, to a battery module case in which sub-battery modules are slidably mounted in a vertical or horizontal direction, wherein each sub-battery module comprises one or more battery cells, electrode tabs extending in one direction from the respective battery cells, and a pouched type case consisting of aluminum laminate sheets for covering the surfaces of the battery cells, except for the surfaces on which the electrode tabs are formed. The battery module case of the present invention is formed into an assembly type structure to be coupled to the outer surfaces of the sub-battery modules, wherein the outer surfaces include surfaces on which the electrode tabs are formed. At least two or more sub-battery modules are stacked and arranged in parallel, such that the surfaces on which the electrode tabs are formed are aligned in the same direction. |

1. A battery module case comprising: each sub-battery module slidably mounted in a vertical or horizontal direction; and formed in an assembly type structure to be coupled to outer peripheral surfaces of the sub-battery modules,
wherein each sub-battery module includes one or more battery cells, electrode tabs extending in one direction from the respective battery cells, and a pouched type case consisting of aluminum laminate sheets for covering remaining surfaces of the battery cells, except for the surfaces on which the electrode tabs are formed, the outer peripheral surfaces include surfaces on which the electrode tabs are formed, and at least two or more sub-battery modules are stacked and arranged in parallel, such that the surfaces on which the electrode tabs are formed are aligned in the same direction, the battery module case includes: an upper housing coupled to surfaces on which the electrode tabs of the sub-battery module are formed; a lower housing formed in a shape in which two surfaces are orthogonal to each other, and in which a plurality of partition wall parts are formed on an inner side surface thereof so that each sub-battery module is slidably mounted in a vertical or horizontal direction, and the opposite side surface to the surface on which the electrode tabs of the sub-battery module are formed and one outer peripheral surface adjacent thereto are coupled to each other; and a side surface housing coupled to a remaining outer peripheral surface which is not coupled by the upper and lower housings, wherein the upper, the lower, and the side surface housings are coupled to each other. |
