Abstract: The battery pack of the present disclosure comprises a pack housing forming a plurality of areas; a plurality of battery modules each disposed in the plurality of areas; and a cover which is disposed above the plurality of battery modules and on which a plurality of exhaust devices corresponding to each of the plurality of battery modules are formed, wherein each of the plurality of exhaust devices is be opened or closed by the pressure of a gas generated at a corresponding battery module among the plurality of battery modules.

Abstract: A battery pack includes a pack housing, at least one battery module disposed inside the pack housing, and a vent hole connecting inside and outside of the pack housing, wherein the battery module includes a plurality of battery cells and a first thermal propagation (TP) blocking member disposed between the plurality of battery cells.

Abstract: A battery pack includes a pack housing including a plurality of accommodation spaces; a partition member coupled to the pack housing and partitioning a space of the pack housing into the plurality of accommodation spaces; a plurality of pack units respectively disposed in the plurality of accommodation spaces; a first pack cover in contact with the partition member and covering at least one of the plurality of accommodation spaces or the pack unit; and a second pack cover covering the first pack cover and the pack housing.

Abstract: A battery module is disclosed. The battery module includes a cell assembly including a plurality of battery cells, each of the plurality of battery cells including an electrode accommodation portion accommodating an electrode assembly, and an electrode lead protruding from the electrode accommodation portion and coupled to the electrode assembly; a module housing accommodating the cell assembly; a bus bar unit including a plurality of slits in which the electrode leads are inserted respectively, and a bus bar coupled to the electrode leads; and a guide member positioned between the electrode accommodation portion and the bus bar unit, the guide member including a plurality of openings through which the electrode leads pass.

Abstract: A battery pack includes a cell assembly unit including a plurality of battery cells and a bus bar configured to electrically connect the plurality of battery cells, a frame unit accommodating the cell assembly unit, and a bracket unit fixing the cell assembly unit to the frame unit. The bracket unit and the frame unit form a flow path through which a gas is discharged. A reverse flow prevention member is disposed between the bus bar and the bracket unit. The reverse flow prevention member includes a plurality of gas permeation holes, each of which extends from one end facing the bus bar and leads to another end facing the flow path.

Abstract: A battery pack includes a number of secondary battery cells, and a frame unit including a number of sealed compartments in which the number of secondary battery cells are dispersedly accommodated, and configured to, when flames or gas are generated in a secondary battery cell disposed in one of the compartments, discharge the flames or gas.
