The present invention relates to a battery module. The battery module according to the present invention includes a housing having an internal accommodation space; and a plurality of battery cells disposed in the internal accommodation space, in which the housing includes a weld joint in which a first base material of a first aluminum-based alloy and a second base material of a second aluminum-based alloy are welded, and at least a partial region of a bead surface of the weld joint is located inward with respect to a reference plane, with an imaginary plane, which connects an outer surface of the first base material and an outer surface of the second base material in contact with the weld joint, as the reference plane.

Battery module

A battery module includes a plurality of secondary battery cells, including at least one weak sealing portion, and a housing unit in which the plurality of secondary battery cells are accommodated. The housing unit includes a flame discharge opening formed to face the weak sealing portion such that flame or exhaust gas, discharged from the weak sealing portion, is induced to be discharged outwardly of the housing unit.

A battery module includes a housing that includes an internal space, a cell stack accommodated in the internal space and including a plurality of battery cells stacked in a first direction and a plurality of thermal blocking members disposed between battery cells in the plurality of battery cells, a plurality of electrically conductive members electrically connected to the plurality of battery cells, and a frame supporting the plurality of electrically conductive members. Each battery cell includes an electrode assembly and an electrode accommodating portion accommodating the electrode assembly. At least one of the thermal blocking members includes: a body portion configured to face the electrode accommodating portion and blocking heat propagation between the plurality of battery cells, and one or more blocking portions extending from the body portion in a second direction perpendicular to the first direction, and configured to at least partially block gas flow in the first direction.

The present disclosure relates to a high voltage battery module and a pack, in which a thermal barrier is mounted, and, more particularly, relates to a battery module comprising a cell assembly stacked with a plurality of secondary battery cell; a housing accommodating the cell assembly, a thermal barrier is placed in the housing, wherein the thermal barrier comprises a heat resistant layer to prevent propagation of heat or flame from a secondary battery cell to an neighboring secondary battery cell.

Battery module comprising thermal barrier and pack

A battery module includes: first and second sub-battery modules, respectively comprising a cell stack including a plurality of battery cells, and a bus bar assembly disposed at least one side of the cell stack; and a central wall disposed between the first and second sub-battery modules, wherein the central wall includes a hollow venting passage formed in a direction intersecting the direction that the first and second sub-battery modules are disposed such that gas or flames occurring in the first or second sub-battery modules are allowed to flow from inside the battery module through the hollow venting passage to the outside of the battery module.

Battery module including the center wall

An eco-friendly power source, such as a battery module provided for a transportation vehicle includes 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, and a lower cover coupled to the first sub-module and the second sub-module. 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.

Eco-friendly power source such as battery module for a transportation vehicle and method of manufacturing battery module

An eco-friendly power source such as a battery module is provided for a transportation vehicle, including: a first sub-module and a second sub-module respectively including a cell stack in which a plurality of battery cells are stacked; and a central wall disposed between the first sub-module and the second sub-module, wherein the central wall includes a first central wall facing the first sub-module and a second central wall facing the second sub-module, wherein the first central wall has a rotationary symmetrical shape of the second central wall around a first axis.

Eco-friendly power source such as battery module for transportation vehicle

A battery module includes at least one cell group, and a heat dissipating member coupled to one side of the at least one cell group to externally dissipate heat generated in the at least one cell group, wherein the at least one cell group includes at least one battery cell stack, a flame retardant cover coupled to the battery cell stack to encase both side surfaces and an upper portion of the battery cell stack, and a flame retardant member disposed between an upper surface of the battery cell stack and the flame retardant cover and formed of a porous material.
