Abstract: Disclosed is a battery pack in which a seating recess is provided in a horizontal frame so that connection members pass through the horizontal frame through the seating recess, thereby maximizing a height of the horizontal frame. A vertical frame cover is provided in a vertical frame to secure a height of the vertical frame side in each module space. A sealing member is provided in the seating recess to seal the seating recess. A double shielding structure, including a module space cover shielding each module space and a battery pack cover shielding a battery pack housing as a whole, is provided to maximize airtightness of the battery pack.

Abstract: A battery cell assembly includes a plurality of battery cells, a bus-bar assembly to which electrode leads of the plurality of battery cells are coupled, and a barrier interposed between the plurality of battery cells and coupled to the bus-bar assembly.

Abstract: A battery pack includes a cell group including a number of secondary battery cells; a frame accommodating the cell group therein; and a bracket coupled to the frame, linked to the cell group to fix the cell group to the frame, and defining a vent space together with the frame to form a path, through which flames or gas are discharged, when the flames or the gas is generated in one of the secondary battery cells.

Abstract: The following disclosure relates to a battery pack case, and more particularly, to a battery pack case in which an internal space defined by a plate and an outer frame is partitioned into a plurality of module spaces so that a plurality of battery modules are individually seated and in which a plurality of channels are formed inside a left frame and a right frame of the outer frame and have a structure in which they are in communication with internal spaces of each of the plurality of partitioned module spaces to be able to discharge a harmful material generated at the time of occurrence of an issue in the battery module to the outside through the plurality of channels.

Abstract: The battery module includes: a battery cell stack in which a plurality of battery cells are stacked; a terminal block electrically connected to the battery cell stack; a housing accommodating the battery cell stack in a form of an opened side surface on which the terminal block is formed; an insulating cover covering an opening of the housing, a terminal block through hole exposing the terminal block to the outside being formed on one side of the insulating cover; and a terminal block protective cover accommodating the terminal block exposed to the outside. A portion of the terminal block protective cover being melted in a situation of a certain temperature or higher to cover and insulate an outer surface of the terminal block, thereby insulating the terminal block and preventing the short circuit in a thermal runaway situation.
