Abstract: An eco-friendly power source, such as a battery module for a transportation vehicle, including a housing having an internal space; a cell stack accommodated in the internal space and including a plurality of battery cells; a busbar assembly including a busbar electrically connecting the plurality of battery cells to each other; and an insulation cover assembly preventing short circuit between the busbar and the housing, wherein the insulation cover assembly includes a cover frame disposed between the busbar and the housing; and a short-circuit prevention member coupled to the cover frame.

Abstract: A battery module is disclosed. In some implementations, the battery module includes: a housing having an internal space, a cell stack in which a plurality of battery cells and a first heat blocking member blocking heat propagation between the plurality of battery cells are stacked, and a second heat blocking member disposed between the cell stack and the housing, wherein at least a portion of the first heat blocking member is in contact with the second heat blocking member.

Abstract: A battery module is disclosed. The battery module includes a battery cell assembly including a plurality of battery cells; a case assembly accommodating the battery cell assembly; the case assembly including a top case positioned on the battery cell assembly; and a bus bar assembly including a bus bar unit electrically connecting the plurality of battery cells, a connection frame connected to the bus bar unit and positioned under the top case, and an expansion sheet positioned between the connection frame and the top case. When a heat is applied to the expansion sheet and a temperature of the expansion sheet is higher than or equal to a predetermined temperature, the expansion sheet expands toward the top case.

Abstract: A battery module which uses a flexible printed circuit board (FPCB) to provide a transmission path of information on the voltage or temperature thereof sensed by a bus bar. The battery module may have a smaller size in a height direction compared to a case of using a rigid printed circuit board (RPCB) or a wire instead of the FPCB to provide the transmission path of the information on the voltage or temperature, and may thus have improved energy efficiency per volume.

Abstract: Provided are a more easily assembled sensing assembly and a battery module comprising the same by having a simplified process through a connection structure between a terminal portion and a signal connection portion which are respectively coupled to a case and lead portions of a battery cell, thereby solving a problem that an additional process is necessary for a conventional sensing block to be coupled to leads of the secondary batteries after being coupled to a case.
