1. A sub-battery container used in a battery container for receiving a plurality of battery modules, the sub-battery container comprising: two side plates standing to face each other at both side walls of the sub-battery container; andhorizontal support bars disposed in parallel,wherein one longitudinal end of each horizontal support bar is coupled to one side plate of the two side plates and the other longitudinal end of each horizontal support bar is coupled to the other side plate of the two side plates such that each horizontal support bar is perpendicularly coupled to the two side plates,wherein the horizontal support bars include an upper horizontal support bar and a lower horizontal support bar disposed under the upper horizontal support bar,wherein the lower horizontal support bar and the upper horizontal support bar have uneven portions, respectively,wherein an uneven portion of the lower horizontal support bar is formed at a bottom of the lower horizontal support bar and an uneven portion of the upper horizontal support bar is formed at a top of the upper horizontal support bar such that a convex portion of one of the uneven portions is inserted into a concave portion of the other one thereof when two sub-battery containers are stacked, andwherein opposite ends of each of the two side plates are bent in a C shape to form concave portions to receive a fixing plate to be inserted into the concave portions. 2. The sub-battery container used in a battery container according to claim 1, further comprising a top plate whose both ends are fixed to the top of the upper horizontal support bars. 3. The sub-battery container used in a battery container according to claim 1, wherein the uneven portions have a convex portion formed at the top of the upper horizontal support bar and a concave portion formed at the bottom of the lower horizontal support bar. 4. The sub-battery container used in a battery container according to claim 1, wherein the uneven portions have a convex portion formed at the bottom of the lower horizontal support bar and a concave portion formed at the top of the upper horizontal support bar. 5. The sub-battery container used in a battery container according to claim 1, wherein at least one of the horizontal support bars has an opening. 6. The sub-battery container used in a battery container according to claim 1, further comprising another upper horizontal support bar and another lower horizontal support bar to provide two upper horizontal support bars and two lower horizontal support bars. 7. A battery container for receiving a plurality of battery modules, comprising: a plurality of sub-battery containers including two side plates standing to face each other at both side walls thereof; andhorizontal support bars disposed in parallel,wherein one longitudinal end of each horizontal support bar is coupled to one side plate of the two side plates and the other longitudinal end of each horizontal support bar is coupled to the other side plate of the two side plates such that each horizontal support bar is perpendicularly coupled to the two side plates,wherein the horizontal support bars include an upper horizontal support bar and a lower horizontal support bar disposed under the upper horizontal support bar,wherein the lower horizontal support bar and the upper horizontal support bar have uneven portions, respectively,wherein an uneven portion of the lower horizontal support bar is formed at a bottom of the lower horizontal support bar and an uneven portion of the upper horizontal support bar is formed at a top of the upper horizontal support bar,wherein the plurality of sub-battery containers are stacked by mutually coupling such that one sub-battery container is stacked on top of another sub-battery container adjacent said one sub-battery container such that the uneven portion of the lower horizontal support bar of said sub-battery container and the uneven portion of the upper horizontal support bar of said another sub-battery container mesh with each other,wherein opposite ends of each of the two side plates are bent in a C shape to form concave portions, andwherein the battery container further comprises two fixing plates inserted into the concave portions of the sides plates at opposite ends of the battery container along a stacking direction of the sub-battery containers. 8. The battery container according to claim 7, wherein the upper horizontal support bar is provided in plurality, and wherein each sub-battery container further includes a top plate whose both ends are fixed to the top of the upper horizontal support bars. 9. The battery container according to claim 7, wherein the uneven portions have a convex portion formed at the top of the upper horizontal support bar and a concave portion formed at the bottom of the lower horizontal support bar. 10. The battery container according to claim 7, wherein the uneven portions have a convex portion formed at the bottom of the lower horizontal support bar and a concave portion formed at the top of the upper horizontal support bar. 11. The battery container according to claim 7, wherein at least one of the horizontal support bars included in each sub-battery container has an opening. 12. The battery container according to claim 7, wherein each sub-battery container includes another upper horizontal support bar and another lower horizontal support bar to provide two upper horizontal support bars and two lower horizontal support bars. 13. A battery pack, comprising a plurality of battery modules received in the battery container defined in claim 7.
