Abstract

A power source pack is arranged on a floor in such a manner that the vehicle front side is positioned higher than the vehicle rear side. Specifically, the front side of the power source pack is placed on a cross member qualified as a structural member that is fixed to traverse the vehicle on the floor. By such a configuration, it is possible to provide a structure for mounting a power source pack that is configured to be less vulnerable to the heat penetrating from a lower surface of the floor to the interior of a cabin even if the power source pack is arranged on the floor.

Claims

1. A structure for mounting a power source pack that houses a power source,

said power source pack being provided on a floor panel of a vehicle, and

said power source pack being inclined such that said vehicle front side of said power source pack is positioned higher than said vehicle rear side thereof by placing said front side of said power source pack on a cross member that is fixed on said floor panel of said vehicle.

2. The structure for mounting a power source pack according to claim 1, wherein

said vehicle includes an engine as a driving source, and

an exhaust passage is arranged below said floor panel and said power source pack is arranged above said exhaust passage.

3. The structure for mounting a power source pack according to claim 2, wherein

said exhaust passage includes a catalytic device and said power source pack is arranged above said catalytic device.

5. The structure for mounting a power source pack according to claim 1, wherein

said power source pack houses a power source module and an equipment portion, and

said equipment portion is arranged on said vehicle front side in said power source pack.

6. The structure for mounting a power source pack according to claim 1, wherein

a liquid discharging portion is provided on said vehicle rear side of said power source pack.

7. The structure for mounting a power source pack according to claim 1, wherein

said power source pack is arranged between a driver'"'"'s seat and a passenger seat of said vehicle.

8. The structure for mounting a power source pack according to claim 1, wherein

said vehicle is a hybrid vehicle that can output power of an engine and/or an electric motor to a drive shaft.
