[0028] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0029] As described in the background technology, when the energy storage container is used in an environment with high humidity, water vapor condenses easily on the surface of the battery shell to produce water droplets, which has an adverse effect on the battery life. In order to solve the above problem, the present application proposes the following solution.

[0030] like Figure 1 As shown, an embodiment of the present application provides an energy storage container, comprising: a box body 100; a battery compartment 10, arranged inside the box body 100, the battery compartment 10 comprising a plurality of battery racks 11; a dehumidification device 20, arranged in the box body 100, the dehumidification device 20 comprising a dehumidifier 21 and an air inlet duct 22 connected to the dehumidifier 21; wherein the air inlet duct 22 extends into the battery compartment 10, and an air inlet 221 is opened on the air inlet duct 22.

[0031] Specifically, Figure 1 As shown, the box 100 has a battery compartment 10, and a plurality of battery racks 11 are arranged side by side in the battery compartment 10. A plurality of battery packs are stored on the battery racks 11. In addition to the battery compartment 10, the box 100 also has a main control room, air conditioner, etc. The box 100 has a top plate (not shown in the figure), and the dehumidifier 21 is installed in the box 100. Figure 1 The dehumidifier 21 shown is installed in the main control room and close to the top plate, and the air inlet pipeline 22 is connected to the dehumidifier 21.

[0032] In this embodiment, the air inlet duct 22 extends into the battery compartment 10, and an air inlet 221 is opened on the air inlet duct 22. With this arrangement, the originally humid air in the battery compartment 10 can be sucked into the dehumidifier 21 for dehumidification through the air inlet duct 22, which can effectively adjust the air humidity in the battery compartment 10 to ensure that the air humidity in the compartment is maintained at a relatively stable level, avoid condensation of water vapor on the surface of the battery shell to produce water droplets, thereby increasing the battery life and helping to increase the number of batteries integrated inside the battery compartment.

[0033] In one embodiment, a plurality of air inlets 221 are provided, and each air inlet 221 is disposed in one-to-one correspondence with each battery rack 11 .

[0034] For details, please refer to Figure 1 and Figure 2 The air inlet duct 22 is provided with a plurality of air inlets 221, and each air inlet 221 is provided corresponding to a battery rack 11. As an example, five battery racks 11 are provided in the battery compartment 10, and five air inlets 221 are provided on the ventilation duct, and each air inlet 221 is provided corresponding to each battery rack 11.

[0035] Such an arrangement can ensure that the air near each battery rack 11 can be sucked into the dehumidifier 21, and good gas flow can be formed inside the battery compartment 10, avoiding the situation where the air humidity around the dehumidifier 21 is low and the air humidity far away from the dehumidifier 21 is high, thereby improving the humidity balance in the battery compartment 10 and facilitating the precise control of the humidity in the battery compartment 10.

[0036] In one embodiment, the dehumidifier 21 is disposed outside the battery compartment 10 ; the outlet of the air inlet pipe 22 is connected to the dehumidifier 21 , and the air inlet 221 of the air inlet pipe 22 extends to a side of the battery compartment 10 away from the dehumidifier 21 .

[0037] like Figure 1 As shown, the dehumidifier 21 is arranged outside the battery compartment 10 to facilitate drainage of the dehumidifier 21. The outlet of the air inlet pipeline 22 is connected to the dehumidifier 21. After the humid air enters the air inlet pipeline 22 from the air inlet 221, it enters the dehumidifier 21 for dehumidification.

[0038] Furthermore, the air inlet 221 at the end of the air inlet pipe 22 extends to the side of the battery compartment 10 away from the dehumidifier 21, Figure 1 and Figure 2 It can be seen that the air inlet 221 at the end of the air inlet duct 22 is as close to the end of the box body 100 as possible, which effectively expands the coverage of the air inlet duct 22 so as to disturb the air in the battery compartment 10 to a greater extent and form good gas flow inside the battery compartment 10.

[0039] In one embodiment, the dehumidification device 20 also includes a return air duct 23 ; the inlet of the return air duct 23 is connected to the dehumidifier 21 , and the air outlet 231 of the return air duct 23 extends into the battery compartment 10 and is away from the air inlet 221 of the air inlet duct 22 .

[0040] Specifically, the inlet of the return air duct 23 is connected to the dehumidifier 21, and the return air duct 23 can be used to discharge the dry air dehumidified by the dehumidifier 21; further, the air outlet 231 of the return air duct 23 extends into the battery compartment 10 and is away from the air inlet 221 of the air inlet duct 22. Such an arrangement can form good gas flow in the battery compartment 10, so that the air in the entire battery compartment 10 can circulate through the dehumidifier 21 for drying treatment, thereby improving the humidity balance in the battery compartment 10.

[0041] In one embodiment, the air outlet 231 of the return air duct 23 extends to the bottom of the box 100. Specifically, when the air outlet 231 of the return air duct 23 is set at a position close to the bottom of the box 100, the gas blown out of the air outlet 231 can stir the airflow in the battery compartment 10, so that the air in the battery compartment 10 is stirred and circulated as much as possible, and the humid air at the bottom of the battery compartment is stirred to move upward, dehumidified through the air inlet duct 22 and the dehumidifier 21, and then the dry air is sent out through the air outlet 231 of the return air duct 23, thereby forming a cycle, accelerating the drying efficiency in the battery compartment, and avoiding the situation where only the gas in the upper half of the battery compartment 10 is dried, the lower half is humid, and the humidity difference in some areas of the battery compartment is too large.

[0042] Optionally, the return air duct 23 can also be configured to extend along the bottom of the box body 100 to pass through each battery rack 11, and an air outlet 231 is set at a position corresponding to each battery rack 11, so as to further increase the circulation intensity and range, which can greatly improve the humidity balance in the battery compartment 10 and further improve the accuracy of humidity control in the battery compartment 10.

[0043] In one embodiment, the dehumidification device 20 further includes a drain pipe 24 , which is connected to the water outlet 211 of the dehumidifier 21 .

[0044] By connecting the drain pipe 24 to the water outlet 211 of the dehumidifier 21, the water generated by the dehumidifier 21 during the dehumidification process is discharged through the drain pipe 24. As an example, Figure 1 As shown, the drain pipe 24 is attached to and arranged on the outer side wall of the side plate of the battery compartment 10 .

[0045] In one embodiment, the outlet of the drain pipe 24 extends to the bottom of the box body 100, and the bottom of the box body 100 is provided with an opening corresponding to the outlet of the drain pipe 24, which can conveniently discharge the water generated during the dehumidification process to the outside of the energy storage container.

[0046] In some embodiments, the drain pipe 24 may also be merged with the drainage pipeline in the energy storage container, so as to reduce the number of openings in the energy storage container and effectively discharge the water generated during the dehumidification process to the outside of the energy storage container.

[0047] In one embodiment, the air inlet 221 on the air inlet duct 22 faces the battery rack 11 .

[0048] Specifically, an air inlet 221 may be opened on the side of the air inlet duct 22 facing the battery rack 11, so that the air near the battery rack 11 can be more specifically sucked into the air inlet duct 22, and then dehumidified by the dehumidifier 21. Specifically, when the air inlet duct 22 is located directly above the battery rack 11, the air inlet 221 may be opened directly below the air inlet duct 22; when the air inlet duct 22 is located above the battery rack, the air inlet 221 may be opened below the side of the air inlet duct 22 to ensure that the air inlet 221 faces the battery rack 11.

[0049] For example, the energy storage container described in any of the above embodiments may be a liquid-cooled container.

[0050] As a mainstream energy storage box, liquid-cooled containers are often in a working environment with high air humidity. When the liquid cooling system in the liquid-cooled container cools the battery pack, it is easy for the temperature difference between the battery pack surface and the air to be large. When the air humidity is high, it is common for water vapor to condense on the battery pack surface to produce water droplets. By adding a dehumidification device 20 to the liquid-cooled container, especially adding a dehumidification device 20 to the battery compartment, the humidity level of the battery compartment 10 in the liquid-cooled container can be effectively regulated, reducing the condensation of water vapor on the battery shell surface, preventing the battery from leaking, thermal runaway and other problems, and effectively improving the battery life.

For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.

[0052] It will be apparent to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential features of the present application. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present application.
