[ In this case, both the first blocking plate 24 and the second blocking plate 44 are hingedly turned inward to open all of the openings of the first flow path 72 and the second flow path 74, And then discharged to the second outlet (50) provided with the outlet (90).

FIG. 4 is a view showing an arrangement for assembling a plurality of battery case modules according to an embodiment of the present invention, and FIG. 5 is a view illustrating a large battery module assembled into a plurality of battery case modules.

4 to 5 show a plurality of battery case modules 1a to 1d, a pump 90, and a large battery module 100a.

The battery case modules 1a to 1d according to the present embodiment are standardized and all have the same structure. In this case, a large-capacity battery module 100a having a large capacity can be assembled through a simple operation of assembling another battery case module to an arbitrary battery case module.

Hereinafter, the case of assembling using four battery case modules 1a to 1d will be described for convenience of understanding and explanation of the invention. However, Needless to say, the module can be assembled to form a large battery module.

The center of the battery pack 100 is connected to the inlet of the battery case module adjacent to the pump connection point of the neighboring two battery case modules, And an outlet port of the module is assembled correspondingly. This will be described in detail as follows.

4, in the case of the first battery case module 1a to which the pump 90 is connected, the remaining one of the outflow ports (the first outflow port 30a in the figure) The outlet 50a) is provided with a sealing cap.

The first inlet 20a of the first battery case module 1a is associated with the first outlet 30b of the second battery case module 1b. In this case, after the sealing cap provided on the first outlet 30b of the second battery case module 1b is removed, the first contact 22a provided on the first inlet 20a of the first battery case module 1a, Is inserted into the first outlet 30b of the second battery case module 1b to be connected to the third contact 42b of the second battery case module 1b.

The second outlet 50c of the third battery case module 1c is assembled to the second inlet 40a of the first battery case module 1a. The fourth contact 52c provided on the second outlet 50c of the third battery case module 1c after removing the sealing cap provided on the second outlet 50c of the third battery case module 1c, Is inserted into the second inlet 40a of the first battery case module 1a to be connected to the third contact point 42a of the first battery case module 1a.

Here, all the battery case modules 1a to 1d are standardized and have the same structure, and the inner mounting points of the third contacts 42 are assembled corresponding to the protruding length of the first contacts 22, And the inner mounting points of the second contacts 32 are also assembled corresponding to the protruding lengths of the fourth contacts 52 and can be connected to each other.

The second inlet 40b of the second battery case module 1b corresponds to the second outlet 50d of the fourth battery case module 1d and the first inlet 20c of the third battery case module 1c And the first outlet 30d of the fourth battery case module 1d correspond to the first battery case 1d. In this case, the sealing caps provided on the first outlet 30d and the second outlet 50d of the fourth battery case module 1d can be removed.

When the negative pressure is generated in the internal flow path by driving the pump 90 after the assembly of the four battery case modules 1a to 1d is completed, the first inlet 20b of the second battery case module 1b, The second inlet 40c of the case module 1c, the first inlet 20d and the second inlet 40d of the fourth battery case module 1d function as an inlet and the first battery 40a, A ventilation path in which the first outlet 30a of the case module 1a serves as an outlet can be formed. The air sucked into the pump 90 may be discharged to a separately connected duct or the outside.

Here, the contacts to be connected in the process of assembling the battery case modules 1a to 1d to each other may be configured so that the same polarity is connected to each other. For example, when the first inlet 20a of the first battery case module 1a and the first outlet 30b of the second battery case module 1b are assembled corresponding to each other, the first contact 22a and the second contact The second contact 32b may be connected to the positive pole, and the negative pole may be connected to the negative pole.

When the same polarities are connected to each other, a parallel connection can be established between the battery case modules 1a to 1d. In this case, the pump 90 becomes operable even in the event of a short-circuit other than the directly-connected contact of the pump 90 (the second contact 32a of the first battery case module 1a).

6 is a view showing a battery case module according to another embodiment of the present invention and assembly of a large battery module using the same.

Referring to FIG. 6, the polarities of the inlets and outlets corresponding to the battery case modules 1a, 1b, 1d are opposite to each other.

For example, in the first battery case module 1a, the positive terminal and the negative terminal of the first contact 22a provided at the first inlet 20a are connected to the second contact 32a provided at the first outlet 30a, And the positive terminal and the negative terminal of the capacitor C are provided at positions opposite to each other. The positive terminal and the negative terminal of the third contact 42a provided in the second inlet 40a are connected to the positive terminal and the negative terminal of the fourth contact 52a provided in the second outlet 50a, It is installed in the opposite position.

Accordingly, when assembling the large battery module 100b, terminals of different polarities are connected to each other when the contacts of any battery case module are connected to the contacts of the other battery case modules, so that the series connection can be established. When the circuit is configured in series, the number of revolutions (RPM) of the pump 90 and the number of battery case modules can be interlocked. That is, as the number of battery case modules used for assembly increases, the number of revolutions of the pump 90 can be increased.

7 is a cross-sectional view of a battery case module according to another embodiment of the present invention.

7, a first flow path 72e connecting the first inlet 20e and the first outlet 30e is formed in the middle portion of the battery case module 1e, 2 outlet port 50e of the battery case module 1e while intersecting with the second flow path 74e to partition the four spaces in the battery case module 1e.

With this structure, instead of installing two battery units as described above, four battery units 112, 114, 116, and 118 can be installed in each of the divided spaces.

A method of assembling a large battery module by assembling with another battery case module can be performed by the same principle as described above with respect to the previous embodiments.

Although the present invention has been described on the assumption that the number of contacts provided in one battery case module is four, it is only one embodiment, and it is needless to say that the number of contacts may be increased or decreased as necessary.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the following claims And changes may be made without departing from the spirit and scope of the invention.
