Abstract: A battery module includes a battery assembly including a plurality of sub-packing units, the plurality of sub-packing units respectively including a cell housing, at least one battery cell accommodated in an internal space of the cell housing, and at least one vent hole disposed in the cell housing and connecting the internal space to an outside of the cell housing, and a flame blocking structure coupled to the battery assembly, and including an inlet hole connected to the vent hole, an inner chamber communicating with the inlet hole, an outlet hole communicating with the inner chamber and the outside, and at least one partition wall protruding into the inner chamber.

Abstract: A battery rack includes: a housing; a module unit provided in the housing, including a plurality of battery cells, and having at least one vent hole; and a cooling unit provided to face the vent hole in the housing, and including a cooling line in which a coolant is provided, wherein the cooling line is provided so that at least a portion of an outer periphery thereof is melted by heat generated from the module unit to supply the coolant toward the vent hole.

Abstract: An energy storage system includes: stacked battery modules; and a rack accommodating the battery modules. The rack includes a sidewall disposed on one side of the battery modules, and the sidewall includes a fire-resistant member opposing the battery modules.

Abstract: A battery module is proposed. The battery module includes a plurality of battery sub-modules, and a front cover part configured to cover an outermost stacking surface of the plurality of stacked battery sub-modules. The front cover part includes a front plate including a contact terminal electrically connected to an outside, a bus bar electrically connecting the plurality of battery sub-modules to each other, and a disconnection induction bus bar coupled to an inside end of the contact terminal to press and contact the bus bar, and a switching slider configured to slide between the bus bar and the disconnection induction bus bar.

Abstract: A battery module includes a battery sub-module including a cell support member, at least one battery cell accommodated in the cell support member, and a case provided to partially surround the at least one battery cell, and a first barrier disposed on a first side of the battery sub-module, wherein the at least one battery cell is enclosed and sealed by the cell support member and the case, and the first barrier includes a first protrusion configured to press a part of the case inwardly of the battery sub-module

Abstract: A battery module includes a housing; a first battery cell and a second battery cell accommodated inside the housing; a first conductive member electrically connecting the first battery cell and the second battery cell, partially embedded in the housing to be fixed to the housing, and not exposed to the outside of the housing, and a second conductive member electrically connected to the first conductive member and partially exposed to the outside of the housing.
