Patent ID: 7823672

Claim:
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 two or more sets 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 direction perpendicular to the direction along which said two or more sets of battery cells are stacked for supplying cooling air between each of said two or more sets 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 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, each set of battery cells includes a single layer of battery cells extending in a same direction and being in a same plane, the two or more sets of battery cells is stacked in an orthogonal direction that is orthogonal to the same plane, and the intake chamber extends parallel to the orthogonal direction.
