Abstract: A battery module according to one embodiment of the present disclosure includes: a module case; a cell assembly that is accommodated in the module case and includes a plurality of battery cells; a busbar assembly that includes a busbar frame covering one side of the cell assembly and guiding the connection of electrode leads of the plurality of battery cells, and a terminal busbar electrically connected to the battery cells and configured for electrical connection to the outside; an insulating cover that covers the busbar frame and electrically insulates the electrode leads of the battery cells from the module case, and is provided with a terminal hole through which the end of the terminal busbar passes; and a sealing member that is hook-coupled to the insulating cover, and seals a gap between the terminal busbar and the terminal hole.

Abstract: A venting pressure measuring apparatus measures pressure at which a venting cover of a battery module ruptures, and includes: a pressure jig that allows the venting cover to be placed and supported thereon, and is provided with a pressure space formed to apply pressure to the venting cover; and a top jig that presses the venting cover into close contact with the pressure jig, and is provided with a through hole formed at a position corresponding to the pressure space. A gas flow when venting occurs in the battery module is simulated by shapes of the pressure space and the through hole.

Abstract: A garnishless type hidden lamp applied to a vehicle, may include a light source module, in which an internal lens spaced from an external lens, appearing as a garnish from outside thereof due to a color of a penetrable painting portion which reflects the external light, with an air gap interposed therebetween transmits an internal light of a light source through laser perforation holes to form a laser pattern on the external lens, so that the garnishless type hidden lamp may have the sense of unity with vehicle design by a painting garnish function of the external lens without combination with a separate metal garnish, improve a wow effect using the painting garnish, implement differentiated and customized lighting by only changing the laser pattern.
