More specifically, a battery pack that includes a plurality of modules is mounted lengthwise in a center console installation space between a driver seat and a passenger seat. A cooling air providing means is configured to supply cooling air to a front protion of the battery pack, and a cooling air distributing means is configured to distribute the cooling air provided by the cooling air providing means to each of a plurality of battery modules individually. Finally, a discharge duct means is configured to receive cooling air that has already passed over each of the individual battery modules and discharge the cooling air through a rear portion of the battery pack to outside of a vehicle body. ## Claims ### Claim 1 A battery pack mounting structure of a vehicle, comprising: a battery pack mounted lengthwise in a center console installation space between a driver seat and a passenger seat and including a plurality of battery modules; a cooling air providing means configured to supply cooling air to a front portion of the battery pack; a cooling air distributing means configured to distribute the cooling air provided by the cooling air providing means to each of the plurality of battery modules individually; and a discharge duct means configured to receive cooling air that has already passed over each of the individual battery modules and discharge the cooling air through a rear portion of the battery pack to outside of a vehicle body, wherein: the battery pack, the cooling air providing means, and the cooling air distributing means are integrally modularized and installed on a mounting plate which extends lengthwise in the vehicle, the mounting plate is seated and fixed to a top portion of a center tunnel of a floor panel, the cooling air providing means is a cooling fan installed on the mounting plate in the front portion of the battery pack to provide air via rotational force thereof and blow the provided air into the cooling air distributing means through an exhaust duct, the exhaust duct is opened rearward on the top of the battery pack, the battery pack is configured by placing the plurality of battery modules in series in lengthwise direction of the vehicle, and one end of the cooling air distributing means is connected to the exhaust duct of the cooling fan and a plurality of other ends are each connected respectively to each of the battery modules individually to supply cooling air to each battery module individually from above, wherein the cooling air distributing means is embodied as a plurality of branch ducts which overlap each other longitudinally to provide cooling air from the cooling fan to each of the battery modules individually. ### Claim 2 (depends on 1) The battery pack mounting structure of a vehicle of claim 1, wherein: the mounting plate includes a plurality of curves, wherein both sides are formed to receive a plurality of mounting brackets attached to the center tunnel of a floor panel, and the plurality of mounting brackets are configured to fix the mounting plate to the center tunnel in a particular position. ### Claim 3 (depends on 2) The battery pack mounting structure of a vehicle of claim 2, wherein a sectional structure of the mounting plate is configured to include a center protrusion protruding downward from a center of the mounting plate to form a horizontal plane. ### Claim 4 (depends on 1) The battery pack mounting structure of a vehicle of claim 1, wherein the branch ducts are formed in a shape of a plurality of hollow plates overlapped one on top of the other and placed on top of the battery pack. ### Claim 5 (depends on 1) The battery pack mounting structure of a vehicle of claim 1, wherein the discharge duct means is an outlet duct that is connected from a rear lower side of the battery pack, is branched to both sides of the center tunnel, and is in communication with a center floor reinforcing frame installed on the floor panel of the vehicle in a horizontal direction of the vehicle body to discharge the cooling air to the outside of the vehicle body through an exit opening outside the vehicle body.
