- the housing 3 when the housing 3 is provided with the protruding portion 3g1 and the protruding portion 3f1 and the opening 2s is viewed from the Y direction, The point which extends over between the one end 3h and the other end 3i is different from the third embodiment.
- the protrusions 3g1 and 3f1 and the opening 2s are offset in the X direction without overlapping in the Y direction.
- the present invention is not limited to this example, and the protrusions 3g1 and 3f1 are not limited to this example. May be provided in a state where at least a part of the aperture overlaps the opening 2s in the Y direction.
- protrusion part 3g1, 3f1 is provided in the housing
- protrusion part 3g1 is not limited to this protrusion part 3g1, 3f1. It may be provided.
- protrusion part 3g1 since the circulating flow W1 generated in the introduction passage P1 can be suppressed by the opening 2s and the protrusions 3g1 and 3f1, for example, variation in the temperature of the battery module 4 depending on the location is further ensured. It is easy to be suppressed.
- FIG. 11 is a cross-sectional view of the storage battery system 1E.
- a storage battery system 1E of the embodiment shown in FIG. 11 has the same configuration as the storage battery system 1 of the first embodiment. Therefore, according to this embodiment, the same effect based on the same configuration as that of the first embodiment can be obtained.
- this embodiment is different from the first embodiment in that a plurality of guide plates 2g are provided in the introduction passage P1, for example, as shown in FIG.
- the guide plate 2g and the opening 2s are located on one side in the Z direction with respect to the housing 3 and are aligned in the Y direction. Further, the plurality of guide plates 2g are partially offset from each other so as to go to one side in the Z direction as the distance from the opening 2s increases.
- the guide plate 2g is supported by, for example, the wall 2e (see FIG. 1) and the wall 3e of the container 2 or the wall 2b (ceiling) of the container 2.
- the guide plate 2g has, for example, an inclined surface 2g1 and a vertical surface 2g2.
- the inclined surface 2g1 is inclined so as to approach the floor surface 2a1 (housing 3) as it goes away from the opening 2s, that is, toward the other side in the Y direction.
- the vertical surface 2g2 extends from the other end in the Y direction of the inclined surface 2g1 to the other (downward) in the Z direction.
- the guide plate 2g has a function of deflecting and guiding the air flow W flowing into the introduction passage P1 from the opening 2s toward the floor surface 2a1 (housing 3).
- the guide plate 2g is also referred to as an airflow deflector.
- the guide plate 2g is provided in the introduction passage P1, for example, the air flow W is guided to the housing 3 side by the guide plate 2g, thereby circulating in the introduction passage P1.
- the flow W1 (see FIG. 5) can be suppressed. Therefore, for example, variation in the temperature of the battery module 4 depending on the location can be easily suppressed, and thus the life of the storage battery system 1E can be extended.
- FIG. 12 is an exemplary and schematic cross-sectional view of a first modification of the storage battery system 1E.
- the storage battery system 1F of the modification shown by FIG. 12 is equipped with the structure similar to the storage battery system 1E of the said 4th Embodiment. Therefore, also by this modification, the same effect based on the structure similar to the said 4th Embodiment is acquired.
- the plurality of guide plates 2g are arranged more densely on the center side than on both ends in the Y direction in the introduction passage P1. This is different from the fourth embodiment.
- the distance between the one end portions in the Z direction between the two guide plates 2g adjacent in the Y direction is narrower on the center portion side than the both end portions side in the Y direction.
- the flow velocity of the air flow W that has flowed in from the opening 2s may be higher at the center in the Y direction and lower at both ends in the Y direction.
- the guide plate 2g is more densely concentrated on the center side in the Y direction to increase the resistance, so that the flow velocity of the air flow W toward the other side (downward) in the Z direction is made more uniform. Yes.
- the distance on the other end portion side in the Z direction of the guide plate 2g on the center portion side in the Y direction is equal to the other pitch because the uniformity of the flow velocity is further increased. Therefore, according to the present modification, for example, the guide plate 2g easily suppresses the variation in the cooling performance of the plurality of battery modules 4 due to the air flow W, and thus easily suppresses the variation in the temperature of the battery modules 4 depending on the location.
