  • the module connection portion 413 is provided in a shape in which the cross section thereof is substantially close to the "T" and extends as long as the height of the tray wall 412.
  • the module connection part 413 has a head portion 413a that slides up and down in the grooves 162 of the tray connection parts 160 and 260 so as to conform to the tray connection parts 160 and 260. That is, in the present embodiment, the module connection part 413 is slide-coupled in the vertical direction to the tray connection parts 160 and 260 having a square pillar shape in which the inside is an empty space, and thus the module connection part 413 may be disposed in the empty space. Therefore, when the unit battery modules 100, 200, and 300 are mounted in the tray 410, the tray connection parts 160 and 260 of the unit battery modules 100, 200 and 300 and the module connection parts 413 of the tray 410 are respectively positioned at corresponding positions.
  • the unit battery modules 100, 200, and 300 when the unit battery modules 100, 200, and 300 are mounted in the tray 410, the head of the module connection part 413 is fitted to the grooves 162 of the tray connection parts 160 and 260 so that the flow in the horizontal direction is reduced. Can be suppressed.
  • the unit battery modules 100, 200, and 300 may be vertically bolted onto the tray 410, thereby preventing flow in the vertical direction.
  • both side walls 412 of the tray 410 are connected to the tray connecting portions 160 and 260, and the tray connecting portions 160 and 260 are integrally formed with the side plates forming the common wall W.
