Zusammenfassung: | The present invention relates to a secondary battery module capable of minimizing deformation of a housing, in which a plurality of secondary batteries are mounted in the housing. According to the present invention, the secondary battery module comprises: a plurality of secondary batteries having two side surfaces flat and parallel to each other; and a housing including a bottom part formed in the horizontal direction, two side wall parts vertically erected from both ends of the bottom part in parallel with each other in the longitudinal direction, and a ceiling part extending from the upper end of the side wall parts and disposed in parallel with the bottom part and in which the plurality of secondary batteries are stacked and mounted in the thickness direction, wherein the outermost side surfaces of the secondary batteries on both sides face the side wall parts, respectively. The housing has a rib formed to have a thicker thickness than that of other places on the inside of a corner connecting the bottom part and the side wall part.
본 발명은, 복수 개의 이차전지가 하우징에 탑재되는 이차전지 모듈에 있어서, 평평하며 서로 평행한 두 개의 측면을 갖는 이차전지; 및 가로방향을 따라 형성된 바닥부와 상기 바닥부의 양단에서 세로방향으로 서로 간에 평행하게 수직으로 세워진 두 개의 측벽부 및 상기 측벽부들의 상단을 연장하며 바닥부와 평행하게 배치되는 천정부를 포함하며, 복수 개의 상기 이차전지들이 두께방향을 따라 적층되어 탑재되되, 양측 최외각에 놓인 이차전지의 측면이 각각의 측벽부와 마주하도록 탑재되는 하우징;을 포함하고, 상기 하우징은 바닥부와 측벽부를 연결하는 모서리 내측에는 다른 곳 보다 더 두꺼운 두께를 갖도록 리브(rib)가 형성된 것을 특징으로 한다. |
