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.

Battery module

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.

A battery module includes a housing that includes an internal space, a cell stack accommodated in the internal space and including a plurality of battery cells stacked in a first direction and a plurality of thermal blocking members disposed between battery cells in the plurality of battery cells, a plurality of electrically conductive members electrically connected to the plurality of battery cells, and a frame supporting the plurality of electrically conductive members. Each battery cell includes an electrode assembly and an electrode accommodating portion accommodating the electrode assembly. At least one of the thermal blocking members includes: a body portion configured to face the electrode accommodating portion and blocking heat propagation between the plurality of battery cells, and one or more blocking portions extending from the body portion in a second direction perpendicular to the first direction, and configured to at least partially block gas flow in the first direction.

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.
