The fan 610 according to the exemplary embodiment of the present disclosure may be disposed on the top of the container 1000 to discharge the heat generated in the configuration of the battery module 10 to the outside. The fan 610 may include a cover part disposed to cover the fan 610 outside the container 1000. The fan 610 and the side surface and the cover of the container 1000 may include bolt holes communicating with each other and may be bolted to each other. On the other hand, it is not necessary to use the bolt hole and the bolt as a means for coupling the fan 610 with the cover. The fan 610 or cover may include grooves and protrusions that may engage with each other, or may be joined by welding. In addition, the fan 610 is typically operated for 24 hours to continuously maintain the ventilation inside the container 1000.

Accordingly, by lowering the temperature by ventilating the internal air of the container 1000, the temperature of which is increased by the operation of the components of the battery module 10, it is possible to maintain a relatively lower temperature than when using a conventional energy storage device. As a result, the efficiency of the battery module 10 can be increased and its life can be preserved for a long time.

In addition, according to the embodiment, by placing the air inlet 500 and the air outlet 600 far away from each other, and by placing the air outlet 600 above the air inlet 500, the container 1000 It is possible to circulate the internal air of the whole.

In addition, according to an embodiment of the present disclosure, at least one side of the container 1000 may be disposed at least one, and may further include a door 800 of any one of a sliding type and a sliding type. More specifically, according to an embodiment of the present disclosure, two surfaces except for two surfaces disposed in the long axis direction among the four sides of the container 1000 may be referred to as first and second sides, respectively. At least one of the first and second side surfaces may further include a side door 820 having a sliding type or a sliding type and at least one side. In this case, the opening and closing direction can be opened and closed with the opening and closing direction up and down or left and right, it is a type that can be opened and closed in the form of a normal casement door. In addition, the door 800 may be formed of a metal material including iron, and may use the same material as the battery rack 200, the floor 700, or the container 1000. The above description of the material of the door 800 is merely an example, and the present disclosure is not limited thereto. In another embodiment, glass, plastic, or the like may be used as the material.

For example, as shown in FIG. 5, the container 1000 may include three casement type side doors 820 on the first side. In addition, the first side door 821, the second side door 822, and the third side door 823 may be configured with the same standard and spaced apart by a predetermined interval. In addition, the second side surface may similarly include three side doors. Detailed description of the side door 820 described above is merely an example, and the present disclosure is not limited thereto.

Accordingly, the user can easily perform maintenance and replacement without opening the side door 820, without having to enter the container 1000. In addition, through the opening of the side door 820, the internal air may be quickly ventilated or cooled, thereby extending the efficiency and lifespan of the battery module 10.

6 is a structure of a fluid leak prevention unit according to an embodiment of the present disclosure.

The container 1000 according to the exemplary embodiment of the present disclosure may have a fluid leak prevention part 400 formed at a predetermined height from a bottom surface of the inside of the container 1000 to prevent the fluid from leaking out of the container 1000. It may include. In addition, the fluid leakage preventing part 400 may be disposed on at least one side of the container 1000.

More specifically, the fluid leak prevention part 400 may include a prevention frame 410 folded in a “b” shape and welded to at least a portion of an inner side of the container 1000 as illustrated in FIG. 6. have. The prevention frame 410 may be installed around the container 1000 to correspond to the front and rear doors 810 and the side doors 820. Accordingly, even when the fluid (for example, electrolyte) contained in the pipe 300 and the battery module 10 leaks, it may be prevented from leaking outside the container 1000. Detailed form of the above-described fluid leak prevention unit 400 is only an example, the present disclosure is not limited thereto.

In addition, according to one embodiment of the present disclosure, the fluid leak prevention part 400 may be formed at a predetermined height based on an expected water level derived when all the fluid inside the battery module 10 and the pipe 300 leaks. Can be. More specifically, the height from the bottom surface inside the container 1000 to the top of the prevention frame 410 may be preset above the expected leak level of the fluid. Here, the estimated leakage level of the fluid is calculated based on at least part of the volume of the fluid included in the pipe 300 and the battery module 10 and the bottom area of the container 1000 on the assumption that all of the fluid leaks. Can be. Through this, even when the total amount of the fluid inside the pipe 300 and the battery module 10 comes out, the fluid may not leak outside the container 1000. In addition, secondary damage such as surrounding soil contamination due to fluid leakage may be prevented in advance.

In addition, the fluid leak prevention part 400 according to the exemplary embodiment of the present disclosure may further include a patch 420 disposed between the prevention frame 410 and the side door 820. More specifically, a side door 820 of a hinge type may be disposed on the first side or the second side of the container 1000. In addition, the patch 420 may be disposed between the side door 820 and the prevention frame 410 and may be a thin plate having variability. Accordingly, when the side door 820 is opened or closed, leakage of the fluid may be prevented by filling the gap between the side door 820 and the prevention frame 410 regardless of opening or closing of the side door 820.

Further, according to one embodiment of the present disclosure, at least one of the bottom surface of the container 1000, at least one side of the container 1000 to a predetermined height, and the fluid leakage preventing part 400 may be formed of a component that does not react with the fluid. Acid resistant paint can be applied. More specifically, the acid-resistant paint may be applied to the components that can come into contact with the fluid in case the entire fluid flows out and rises from the bottom of the container 1000 to the highest level. For example, the bottom surface of the container 1000, some of the sides of the container 1000 to a predetermined height, a portion of the frame included in the battery rack 200 to a predetermined height, and the prevention frame 410. Acid-resistant paint can be applied to Here, the acid resistant paint may be a product of acid paint AP-101 having high chemical resistance to prevent the fluid (eg, electrolyte) from reacting with the metal. Detailed description of the application site and the product of the above-mentioned acid-resistant paint is only an example, and the present disclosure is not limited thereto.

Accordingly, the container 1000 according to the embodiment of the present disclosure may stably accommodate the battery module 10 through the battery rack 200 and at the same time, arrange each component with high space efficiency. In addition, the manager may easily perform maintenance and management of the battery module 10 through the side door 820 and the floor 700.

In addition, the fluid (eg, electrolyte) that may leak from the pipe 300 and the battery module 10 may not be exposed to the outside of the container 1000, thereby protecting the surrounding environment and facilitating the settlement even in case of an accident. have. In addition, even when the fluid leaks, the components inside the container 1000 may not be chemically reacted to be maintained intact.
