A rechargeable battery module may include: a plurality of unit cells arranged in a first direction and electrically coupled via a bus bar, including a pair of outermost unit cells at opposite ends of the first direction; an end plate supporting the outermost unit cells; side plates at opposite ends of a second direction to support side surfaces of the unit cells; a support member supporting the unit cells at a lower end of a third direction; and welding bushes extended in the third direction at opposite ends of the end plate in the second direction and opposite ends of the side plates in the first direction. Each welding bush may include a cylinder member to which the end plate and one of the side plates are welded, and a cap member combined with at least one of opposite ends of the cylinder member.

Rechargeable battery module including welding bushes

A rechargeable battery module includes unit cells that are arranged in a first direction, a bus bar that electrically connects the unit cells, a pair of end plates that are spaced apart from each other along the first direction at opposite ends of the unit cells to support the unit cells, and at least one side plate between the pair of end plates and connected to the pair of end plates, the at least one side plate extending along the unit cells and spaced apart from the unit cells a predetermined distance, wherein the side plate includes a stepped portion facing the unit cells.

Rechargeable battery module

A rechargeable battery pack including unit cells each including a rechargeable battery, barriers coupled to each other at an outer circumference of the unit cells and each located between respective ones of the unit cells, and a pack housing that accommodates the unit cells and the barriers, and that is coupled to the barriers by tight-fitting.

Rechargable battery pack

A rechargeable battery pack is disclosed. In one aspect, the rechargeable battery pack includes multiple a plurality of sets of unit cells adjacently placed to each other, wherein each unit cell includes a rechargeable battery and a plurality of rechargeable battery modules each configured to electrically connect a corresponding set of the unit cells to each other, wherein each rechargeable battery module includes a pair of end plates respectively placed on outermost opposing sides thereof. The rechargeable battery pack also includes a coupling member connecting the end plates of the rechargeable battery modules to each other. Each of the end plates includes a first flange having a first width and extending from a bent portion of a main body to be fastened to the coupling member and a second flange having a second width smaller than the first width and extending from a middle portion of the first flange.

Rechargeable battery pack

A rechargeable battery module is disclosed. In one aspect, the battery module includes a plurality of unit cells including first and second outermost unit cells disposed at first and second opposing ends of the unit cells arranged in a first direction, wherein the unit cells have top and bottom surfaces opposing each other. The battery module also includes a bus bar holder covering the top surface of the unit cells, a bus bar disposed at the bus bar holder to electrically connect the unit cells and a pair of end plates respectively supporting the first and second outermost unit cells. The battery module further includes a pair of side plates disposed at third and fourth opposing ends of the unit cells arranged in a second direction crossing the first direction, wherein the side plates are connected to the end plates and the bus bar holder.
