<p>PURPOSE: A battery pack apparatus is provided to have stable cooling performance because heated air, which is heated by a battery module in a casing, flows from lower side of a vent to high side, and external air, which is flowed in from an inlet, is smoothly outflow from an outlet to outside, after contacting with the surface of the battery module. CONSTITUTION: A battery pack apparatus comprises a casing(2), an inlet(5), an outlet(6), and a vent in casing(7). A battery module is composed by laminating and arranging a plurality of a battery cell. The casing accept a battery module inside thereof. The inlet in installed in the casing. The outlet introduces external air to inside the casing. The outlet is installed a location higher than the location of the inlet in casing for exhausting. The vent connects the inlet and the outlet along a direction inclined to perpendicular direction.</p> |
