The battery is charged,
Although a chemical reaction occurs during discharge to generate heat, the conventional battery case contains the battery cells in close contact with each other.Therefore, at least one side of the battery cell is in contact with the case. Since the heat is dissipated by conduction, the temperature rise is small, but the inner battery cells are surrounded by battery cells that also generate heat, so the heat dissipation is poor, and they tend to heat up during rapid charging or continuous operation. Will end up. The heating of the battery not only lowers the capacity, but also has the drawback of significantly reducing the life.

A partition body is interposed between each row, and
By securing the space open to the outside, the contact area between the battery cells is reduced and the area exposed to the air is increased, and the heat generated in the battery cells is deprived by the partition body and the air layer. In particular, during running, the ventilation in the space is improved, and the heat dissipation effect is greatly improved. Further, since the initial charging is performed in water, in that case, water flows into the space and is efficiently cooled. Also, when the initial charge is completed and the battery is pulled up from the water, the water that has entered the space is discharged from the air window, but even if the air window does not reach the bottom surface, each row communicates at the bottom. Like the leaked electrolyte, it is surely discharged from the drain hole in the center.

In this embodiment, the partition body is composed of a single plate body. However, a plurality of sheets are arranged vertically with a space between them, or as shown in FIG. 4, the rod 8 or the pipe is used. There is no problem in partitioning by, and the point is that space should be secured between adjacent cells. Therefore, inside the battery case, there may be a case where it is only divided into two sections by one partition, or there are cases where two partitions are arranged orthogonally and divided into four sections, all of which have the same width interval. Not only is it partitioned by, but the width of one battery cell is three, while the other is only one battery cell wide. Furthermore, as shown in FIG.
It is also possible to arrange the plate bodies 4.4 as the partition bodies alternately in the top and bottom in a grid pattern so that spaces are formed in the front, rear, left and right of the battery cells arranged inside. Further, the shape and size of the ventilation window do not have to match the cross-sectional shape of the space, and as shown in the previous figure, it is possible to provide only one round hole 9.9 .. May be provided. Further, the shape and size of the partition body can be freely changed.For example, the temperature distribution can be made uniform by changing the ratio of the partition body and the space according to the temperature rise distribution in the battery case. It may be integrally fixed inside, or may be detachably incorporated. Also, the material of the partition body is not particularly limited.
