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 according to the present disclosure comprises a cell stack comprising a plurality of battery cells; and a module case covering the outside of the cell stack. A module case comprises a first case comprising a rib and a first coupling portion that has a greater thickness than that of the rib and that is connected to a side of the rib; a second case comprising a second coupling portion facing an upper portion of the rib and a side of the first coupling portion; a tunnel portion formed between the rib, the first coupling portion, and the second coupling portion; and a welding portion in which a boundary area of the first coupling portion and the second coupling portion is welded.

Battery module

A battery module includes: a plurality of battery cells stacked in a horizontal direction; a first plate supporting lower sides of the plurality of the battery cells and dissipating heat generated in the battery cells; and a second plate in contact with upper sides of the battery cells and dissipating heat generated in the battery cells, wherein the second plate comprises accommodation grooves to receive corresponding sealing portions formed in the upper sides of the battery cells, wherein a heat transfer material having a dielectric strength of from 10 kV/mm to 30 kV/mm is disposed in the accommodation grooves.

The present invention provides a battery module which includes: a battery stack formed by stacking a plurality of battery cells on each other, each of which includes electrode tabs; a first case unit including a bottom section which surrounds one side of the battery stack and a pair of first sidewalls located on both sides of the battery stack in a direction in which battery cells are stacked; and a second case unit including a top section which surrounds the other side of the battery stack and a pair of second sidewalls located on both sides of the battery stack in the direction in which battery cells are stacked, wherein the first sidewall and the second sidewall are located on both sides of the battery stack in the direction in which battery cells are stacked, in a state in which at least portions thereof are overlapped with each other.

A battery module includes: a plurality of battery cells; a first plate supporting lower surfaces of the battery cells and dissipating heat generated in the battery cells; and a second plate being in contact with upper sides of the battery cells and dissipating heat generated in the battery cells, wherein the second plate includes accommodation grooves to receive sealing portions of the battery cells, and a heat transfer material is disposed in the accommodation grooves.
