Structure of Hybrid Vehicle
First Claim
1. A structure of a hybrid vehicle having an internal combustion engine and a motor, comprising:
- a battery pack that has a secondary battery constituted by a plurality of battery cells stacked in a vehicle traveling direction for supplying electric power to said motor, and an intake chamber provided adjacent to said secondary battery in a substantially horizontal direction perpendicular to the direction along which said plurality of battery cells are stacked for supplying cooling air between each of said plurality of battery cells, and that is arranged on a vehicle floor; and
an exhaust passage having an exhaust port and extending from said internal combustion engine, passing below said vehicle floor, to said exhaust port, whereinsaid exhaust passage is provided so that it passes immediately below said battery pack and passes a position displaced from a position immediately below said intake chamber.

Abstract
A structure of a hybrid vehicle includes a battery pack arranged on a floor panel and an exhaust pipe extending from an engine, passing below the floor panel, to an exhaust port. The battery pack has a secondary battery constituted by a plurality of battery cells stacked in a vehicle traveling direction for supplying electric power to a motor, and an intake chamber provided adjacent to the secondary battery in a substantially horizontal direction perpendicular to the direction along which the plurality of battery cells are stacked for supplying cooling air between each of the plurality of battery cells. The exhaust pipe is provided so that it passes immediately below the battery pack and passes a position displaced from a position immediately below the intake chamber. With such a configuration, a structure of a hybrid vehicle that suppresses reduction in the efficiency of cooling a secondary battery without placing a great limit on routing of an exhaust pipe is provided.

3. A structure of a hybrid vehicle having an internal combustion engine and a motor, comprising:
-
a battery pack that has a secondary battery constituted by a plurality of battery cells stacked in a vehicle width direction for supplying electric power to said motor, an intake chamber provided adjacent to said secondary battery in a substantially horizontal direction perpendicular to the direction along which said plurality of battery cells are stacked for supplying cooling air between each of said plurality of battery cells, and an exhaust chamber arranged opposite to said intake chamber relative to said secondary battery for exhausting the cooling air from between each of said plurality of battery cells, and that is arranged on a vehicle floor; an exhaust passage having an exhaust port and extending from said internal combustion engine, passing below said vehicle floor, to said exhaust port a catalyst portion provided on a route of said exhaust passage for purifying exhaust gas, wherein said exhaust passage is provided so that it passes immediately below said battery pack, and said catalyst portion is arranged at a position displaced from a position immediately below said intake chamber.

4. A structure of a hybrid vehicle having an internal combustion engine and a motor, comprising:
-
a battery pack that has a secondary battery Constituted by a plurality of battery cells stacked in one of a vehicle traveling direction and a vehicle width direction for supplying electric power to said motor, an intake chamber provided adjacent to said secondary battery in a substantially horizontal direction perpendicular to the direction along which said plurality of battery cells are stacked for supplying cooling air between each of said plurality of battery cells, and an exhaust chamber arranged opposite to said intake chamber relative to said secondary battery for exhausting the cooling air from between each of said plurality of battery cells, and that is arranged on a vehicle floor; an exhaust passage having an exhaust port and extending from said internal combustion engine, passing below said vehicle floor, to said exhaust port; and a catalyst portion provided on a route of said exhaust passage for purifying exhaust gas, wherein said exhaust passage is provided so that it passes immediately below said battery pack, and said catalyst portion is arranged at a position displaced from a position immediately below said battery pack. - View Dependent Claims (5)

6. A structure of a hybrid vehicle having an internal combustion engine and a motor, comprising:
-
a battery pack that has a secondary battery constituted by a plurality of battery cells stacked in a vehicle width direction for supplying electric power to said motor, an intake chamber provided adjacent to said secondary battery in a substantially horizontal direction perpendicular to the direction along which said plurality of battery cells are stacked for supplying cooling air between each of said plurality of battery cells, and an exhaust chamber arranged opposite to said intake chamber relative to said secondary battery for exhausting the cooling air from between each of said plurality of battery cells, and that is arranged on a vehicle floor; and an exhaust passage having an exhaust port and extending from said internal combustion engine, passing below said vehicle floor, to said exhaust port, wherein said intake chamber and said exhaust chamber each include one end and the other end separated in a direction along which said plurality of battery cells are stacked, and extend from said one end to said other end, when the cooling air is introduced from said one end of said intake chamber and exhausted from said other end of said exhaust chambers, said exhaust passage is provided to pass immediately below said battery pack at a position nearer to said other end than to said one end, and when the cooling air is introduced from said one end of said intake chamber and exhausted from said one end of said exhaust chamber, said exhaust passage is provided to pass immediately below said battery pack at a position nearer to said one end than to said other end.
