PURPOSE: A battery pack assembly for an electric vehicle is provided to simplify the structure by shortening the length of ducts related to cooling. CONSTITUTION: A battery pack assembly(100) for an electric vehicle has a tray(10) having an empty space in which a battery for the electric vehicle is received; an exhaust duct(20) installed on a side of the tray; and a cooling fan(30) installed on the side of the tray, to induce the flowing of air flowing inside the tray. Plural through-holes(11) are formed on the sides of the lower parts of the tray. The cooling air in the tray is exhausted through the exhaust duct. The cooling fan is interposed in the exhaust duct.
