1. A battery module, comprising:
a first sub-module and a second sub-module disposed in a first direction, the first sub-module and the second sub-module respectively including a plurality of battery cells stacked in a second direction, which is perpendicular to the first direction;
a busbar bar assembly disposed on each of the first sub-module and the second sub-module and electrically connected to the plurality of battery cells, and including a first busbar assembly and a second busbar assembly facing each other with the plurality battery cells between in the first direction; and
a terminal portion provided in the first busbar assembly and electrically connected to the plurality of battery cells,
wherein the first sub-module and the second sub-module are disposed to be rotationally symmetrical to each other about a central axis, which is perpendicular to both the first direction and the second direction,
wherein the first busbar assembly is positioned farther from the central axis than the second busbar assembly, and
wherein the terminal portion is disposed closer to one side edge of each of the first sub-module and the second sub-module in the first direction than to the central axis.
