A battery pack includes a pack case accommodating a plurality of battery modules, a bus bar coupled to two battery modules among the plurality of battery modules and interconnecting terminals provided in the two battery modules, and a bus bar cover accommodating the bus bar therein and coupled to the bus bar, wherein the bus bar cover is configured to surround the bus bar and entire upper and side surfaces.

Battery pack

A method for manufacturing a lower case of a battery module includes an extrusion molding operation in which a metal material is extruded to mold a cooling plate member and a sidewall member of a battery module; a forging operation in which an internal surface of the cooling plate member is pressed with a punch, having an edge of a lower end provided vertically to form an accommodation groove; and a forming operation in which an embossed piece, protruding to an external surface of the cooling plate member by forming the accommodation groove, is removed.

Method for manufacturing case of battery module and case of battery module

A battery module includes a plurality of secondary battery cells, a housing member accommodating a plurality of the secondary battery cells therein, and an insulating member disposed on an inner surface of the housing member, preventing flow of electrical current to the housing member, having a heat transfer function to discharge heat of the secondary battery cell externally, and formed to have a predetermined thickness.

Battery module

A battery module includes a module housing including a first plate in which one side is open, a second plate coupled with the first plate to form an internal space, and a partition member disposed across the internal space to couple the first plate with the second plate; and a battery cell stack disposed in the internal space, in which a plurality of battery cells are stacked.

Battery module including partition member

A secondary battery may include a cell body member accommodating an electrode assembly therein; and a heat conductive member disposed between the cell body member and a cooling plate member to form a heat path for transferring heat from the cell body member, wherein the heat conductive member is in contact with the cooling plate member, and wherein a contact area of the cooling plate member and the heat conductive member is smaller than a cross-sectional area of the cell body member parallel to a thickness direction of the electrode assembly.

Secondary battery and battery module having thereof

A battery module according to an embodiment of the present disclosure includes a plurality of secondary battery cells; and a housing member including a cooling plate member, and a heat conductive member provided between the secondary battery cells and the cooling plate member to form a heat path for transferring heat from the secondary battery cells to the cooling plate member, the housing member having the plurality of secondary battery cells accommodated therein, wherein the heat conductive member is comprised such that a portion of the heat conductive member in contact with a secondary battery cell that is supercooled has a lower thermal conductivity than a remaining portion of the heat conductive member.

A secondary battery may include a cell body member accommodating an electrode assembly therein, including three sealing sides and provided adjacently to a cooling plate member; and wherein the cell body member, in contact with a heat conductive member on a lower surface thereof comprises a surface area-increasing groove formed to be concave in the lower surface thereof and the lower surface is a region in which a sealing portion is not formed, wherein the heat conductive member provided in at least a portion between the cell body member and the cooling plate member to form a heat path for transferring heat from the cell body member to the cooling plate member, wherein the surface area-increasing groove includes a curved-region in a cross section in a thickness direction of the cell body member, wherein the curved-region is in contact with the heat conductive member.
