Battery module with improved frame structure and frame assembly therefor

Abstract

Battery module comprising: a plurality of cells (100); a frame assembly including a bottom plate (111) configured to support lower end surfaces of the plurality of cells (100), a pair of side plates (113), which extend perpendicularly from the opposite edge ends of the lower plate (111) and are placed adjacent to an outermost side of the cells (100), and a top plate (114) coupled to an upper end of the side plate (113) to cover an upper portion of the cells (100), wherein the battery module further comprises second guide plates (115) extending perpendicularly from opposite edge ends of the upper plate (114), which are not in contact with the side plates (113) to prevent separation of the plurality of cells (100), and wherein the second guide plates (115) are bent from the upper plate (114) in one piece with the upper plate (114).
