Battery Module, and Battery Pack and Vehicle Including the Same

Abstract

A battery module according to the present disclosure may include a plurality of battery cells, a cell frame configured to accommodate the plurality of battery cells, and a filler filled between the plurality of battery cells. At least a portion of the cell frame may be recessed to form a leakage prevention groove for receiving the filler. The cell frame may include a frame wall forming a perimeter of the cell frame and a cell accommodation portion provided inside the frame wall to accommodate the plurality of battery cells, and wherein the leakage prevention groove may be provided between the frame wall and the cell accommodation portion. Thus, leakage of the filler may be prevented when the filler is injected. Additionally, where cell frames cell are coupled to each other, it is possible to prevent the filler from leaking between the cell frames.

Dependencies are inferred from the claim text.
