Abstract

A structure for mounting a power supply apparatus on a vehicle includes a driver'"'"'s seat and a passenger'"'"'s seat installed within a vehicle compartment and aligned in the vehicle width direction, an instrument panel provided at the vehicle front inside the vehicle compartment and equipped with electronics, a battery pack assembly located between the driver'"'"'s seat and the passenger'"'"'s seat, and wire harnesses electrically connected to the battery pack assembly. The vehicle front side and the vehicle upper side of the wire harnesses face the battery pack assembly. With the above-described configuration, there is provided a structure for mounting a power supply apparatus on a vehicle where the electronics provided at the instrument panel are appropriately protected from an electromagnetic wave.

Claims

1. A structure for mounting a power supply apparatus on a vehicle, comprising:

a first seat and a second seat installed within a vehicle compartment and aligned in a vehicle width direction;

an instrument panel installed at a vehicle front inside the vehicle compartment and equipped with electronics;

a power supply portion located between said first seat and said second seat; and

an electrical component electrically connected to said power supply portion,

a vehicle front side and a vehicle upper side of said electrical component facing said power supply portion.

2. The structure for mounting a power supply apparatus on a vehicle according to claim 1, wherein

said electronics are provided at a position higher than said electrical component.

3. The structure for mounting a power supply apparatus on a vehicle according to claim 1, wherein

said power supply portion includes a side located at a vehicle rear side, and

a recess is formed in such a manner that said side is set back toward a vehicle front, and said electrical component is located in said recess.

4. The structure for mounting a power supply apparatus on a vehicle according to claim 3, wherein

said power supply portion includes a first power supply portion and a second power supply portion,

said first power supply portion and said second power supply portion have a first side and a second side, respectively, located at the vehicle rear side, and

said recess is formed in such a manner that said second power supply portion is provided on said first power supply portion, and said second side is located more rear than said first side.

5. The structure for mounting a power supply apparatus on a vehicle according to claim 4, further comprising

a metallic floor panel provided on a floor inside the vehicle compartment, wherein

said first power supply portion is installed on said floor panel, and

said electrical component has three sides surrounded by said first power supply portion, said second power supply portion and said floor panel.

6. The structure for mounting a power supply apparatus on a vehicle according to claim 4, wherein

said first power supply portion and said second power supply portion include a plurality of power supply cells that are stacked and electrically connected to one another, respectively, and

the power supply cells that are included in said second power supply portion and stacked in a longitudinal direction of the vehicle are larger in number than the power supply cells that are included in said first power supply portion and stacked in the longitudinal direction of the vehicle.

7. The structure for mounting a power supply apparatus on a vehicle according to claim 4, wherein

said first power supply portion and said second power supply portion include a plurality of power supply cells that are stacked and electrically connected to one another, respectively, and the power supply cells included in said second power supply portion are larger in number than the power supply cells included in said first power supply portion

the structure for mounting a power supply apparatus on a vehicle further comprising:

a first exhaust passage through which a cooling air having cooled said plurality of power supply cells is discharged from said first power supply portion; and

a second exhaust passage through which a cooling air having cooled said plurality of power supply cells is discharged from said second power supply portion, wherein

said first exhaust passage and said second exhaust passage extend independently of each other, and

electrical equipment is installed on a path of said first exhaust passage.

8. The structure for mounting a power supply apparatus on a vehicle according to claim 3, wherein

said first seat and said second seat include a driver'"'"'s seat and a passenger'"'"'s seat, respectively,

the structure for mounting a power supply apparatus on a vehicle further comprising:

a center console installed between said driver'"'"'s seat and said passenger'"'"'s seat and housing said power supply portion; and

a rear seat installed at a vehicle rear of said driver'"'"'s seat and said passenger'"'"'s seat, wherein

said center console includes a sidewall located at the vehicle rear side and curved toward said recess.
