A battery is mounted to drive the motor.
Since the battery has a relatively large capacity and often requires a cooling structure for cooling the battery, a relatively large space is required for mounting the battery.

のバッテリに送っている。Various places have been proposed for installing the battery, such as under the underbody, inside the luggage compartment, or under the seat. However, when the battery is installed on the underbody, foreign matter such as muddy water from the outside of the vehicle causes the battery to go out. Less likely to impair function. As the air for cooling the battery, it is considered that the air outside the vehicle is taken in or the air inside the vehicle is used. However, when the air inside the vehicle is used, the temperature of the cooling air is relatively constant. The advantage is that As a vehicle having a cooling structure in which a battery is installed in a vehicle compartment and the air in the vehicle compartment is used to cool the battery,
For example, there is a vehicle described in Japanese Patent Laid-Open No. 2000-233648. In this publication, a space is provided between the front seat and the floor panel, and the battery is arranged in that space. Further, in the above-mentioned publication, a blower for introducing cooling air is provided on the vehicle compartment side of the dash panel that separates the vehicle compartment from the engine room, and the air in the vehicle compartment introduced from the blower is provided in the body member. It is sent to the battery under the front seat through the duct.

いう問題がある。However, as described in the above publication, when the cooling air is introduced from the dash panel into the battery under the seat through the inside of the body member, the air introduction path becomes long. Therefore, there is a problem that the cooling efficiency is not good because the flow resistance of the cooling air increases.

A battery cooling structure has also been proposed in which an air intake port is provided on the upper surface of the battery case that faces the lower surface of the rear seat.
For example, that described in Japanese Patent Application Laid-Open No. 2001-233064 is that. As described above, providing the air intake port directly above the battery makes it possible to shorten the air introduction path, which is convenient in terms of improving cooling efficiency. However, if the battery is arranged in the vehicle compartment and the air intake port is provided directly above the battery, the air intake port becomes closer to the occupant, so that the intake sound generated at the air intake port may be noisy. Further, when the battery is arranged in the vehicle compartment, noise generated at the air outlet becomes a problem even when the air outlet for exhausting the air for cooling the battery to the vehicle compartment is provided directly above the battery.

At 0, the air intake 36 is the rear side step 2
6 side surfaces 26b and 26c. for that reason,
Compared to the case where the air intake port 36 is provided under the seat (that is, above the battery 38), the air intake port 36 is separated from the occupant, so that the intake sound generated at the air intake port 36 is less likely to be heard by the occupant. It feels quiet, and the air introduction path is shorter than when air is introduced from the dash panel through the duct in the body member, so that the flow resistance of the cooling air is reduced and the cooling efficiency is improved. .

なる。Further, in the battery cooling structure 10 shown in the above embodiment, since the air intake port 36 is formed on the substantially vertical side surfaces 26b and 26c of the rear seat side step 26, the air intake port 36 is removed from the air intake port 36. It is less likely that dust or foreign matter will be mixed in or the air intake port 36 will be clogged, and the air intake port 36 will not be blocked by luggage. Further, if the air intake is provided under the seat as in the conventional case, there is a problem that the temperature of the air taken in from the air intake becomes high because the air intake is close to the outlet of the heater. In the battery cooling structure 10 of FIG. 3, since the air intake port 36 is provided in the rear seat side step 26, the distance between the air intake port 36 and the outlet of the heater is increased. The impact will be reduced.

Although it is considered that the air flow may be uncomfortable depending on the occupant, the air intake 36 has the side surfaces 26b, 2 of the rear side step 26 as in the above-described embodiment.
When formed in 6c, the air flow in the vehicle interior 12 caused by the introduction of the cooling air is generated at a place apart from the occupant, and thus the occupant hardly feels the air flow.

Since 6 is far from the driver's seat 14, it becomes more difficult for the driver to hear the intake sound generated at the air intake 36.

Since the air discharge duct 42 is arranged on the side of the battery case 30 opposite to the side on which the air introduction duct 34 is arranged, the air discharge duct 42 and the air introduction duct 34 are arranged with respect to the battery case 30. Compared with the case where and are arranged on the same side, the flow resistance (pressure loss) is small because the change in the direction of the air flow is small.
