Abstract

To make even a high-voltage battery with an extraordinarily large capacity, mountable on a vehicle, a high-voltage battery is installed on a rear floor panel in a rear portion of a fuel cell electric vehicle, and a cooling fan unit for cooling the battery is connected to the high-voltage battery by an exhaust duct. In addition, the cooling fan unit is disposed on a rear side member, in the vicinity, at the vehicle-rear side, of the high voltage battery, and on the same horizontal plane that the high-voltage battery is located on. At the vehicle-rear side of the high-voltage battery, a utility box is provided. An exhaust duct connected to the cooling fan unit is disposed between the utility box and a utility box adjacent thereto.

Claims (15)

1. A high-voltage battery unit mounting structure for a vehicle, wherein the vehicle has a vehicle front and a vehicle rear, and

wherein a high-voltage battery is mounted in a lower portion of the vehicle between the front and the rear of the vehicle, and a cooling fan motor for cooling the high-voltage battery is disposed rearward from the entire high-voltage battery, adjacent to the rear of the vehicle and laterally to a side of the high-voltage battery, and on the same horizontal plane that the high-voltage battery is located on.

2. The high-voltage battery unit mounting structure for the vehicle according to claim 1 , wherein the vehicle is a fuel cell electric vehicle that mounts a fuel cell thereon, wherein a hydrogen pipe for supplying the fuel cell extends in a vehicle fore-and-aft direction, and wherein positions of the hydrogen pipe and the cooling fan motor in a vehicle-height direction are shifted from each other when viewed from the vehicle fore-and-aft direction.

3. The high-voltage battery unit mounting structure for the vehicle according to claim 1 , wherein the cooling fan motor is disposed on a vehicle-body frame member located in the lower portion of the vehicle.

4. The high-voltage battery unit mounting structure for the vehicle according to claim 1 , wherein an exhaust duct which receives exhaust air containing heat generated from the high-voltage battery and through which the exhaust air is flown by the cooling fan motor is disposed in a parting portion between a plurality of article storage boxes provided in a vehicle compartment.

5. The high-voltage battery unit mounting structure for the vehicle according to claim 4 , wherein the article storage boxes are brought into close contact with a vehicle body.

6. The high-voltage battery unit mounting structure for the vehicle according to claim 4 , wherein the article storage boxes are brought into close contact with a rear floor panel.

7. The high-voltage battery unit mounting structure for the vehicle according to claim 1 , wherein an exhaust duct which receives exhaust air containing heat generated from the high-voltage battery and through which the exhaust air is flown by the cooling fan motor is disposed so as to have a discharge port located in a vicinity of a rear-end portion of the vehicle.

8. The high-voltage battery unit mounting structure for the vehicle according to claim 1 , wherein an exhaust duct which receives exhaust air containing heat generated from the high-voltage battery and through which the exhaust air is flown by the cooling fan motor is disposed so as to be surrounded by a plurality of article storage boxes provided in a vehicle compartment.

9. The high-voltage battery unit mounting structure for the vehicle according to claim 1 , wherein an exhaust duct which receives exhaust air containing heat generated from the high-voltage battery and through which the exhaust air is flown by the cooling fan motor is disposed so as to make a space between outer walls of a plurality of article storage boxes provided in a vehicle compartment be an exhaust passage.

10. The high-voltage battery unit mounting structure for the vehicle according to claim 9 , wherein the exhaust duct is connected to an exhaust port disposed on a side of a rear portion of the vehicle.

11. The high-voltage battery unit mounting structure for the vehicle according to claim 1 , wherein the high-voltage battery and the cooling fan motor are arranged on a floor panel under a cargo room in a rear portion of the vehicle.

12. A high-voltage battery unit mounting structure for a vehicle, wherein

a high-voltage battery is mounted in a lower portion of the vehicle, and a cooling fan motor for cooling the high-voltage battery is disposed to a rear side of the entire high-voltage battery and laterally to a side of the high-voltage battery, and on the same horizontal plane that the high-voltage battery is located on,

wherein the vehicle is a fuel cell electric vehicle that mounts a fuel cell thereon, wherein a hydrogen pipe for supplying the fuel cell extends in a vehicle fore-and-aft direction, and wherein positions of the hydrogen pipe and the cooling fan motor in a vehicle-height direction are shifted from each other when viewed from the vehicle fore-and-aft direction.
