[0047] The following will describe the specific implementation of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0048] In the description of the present disclosure, it should be understood that the orientation or positional relationships indicated by terms such as "upper" and "lower" are defined based on the direction of the energy storage cabinet in its normal use state. This is only for the convenience of describing the present disclosure and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, as well as a specific orientation structure and operation. Therefore, it should not be construed as a limitation to the present disclosure. For example, the up and down directions can be the upper and lower directions when the energy storage cabinet is placed normally. The side of the energy storage cabinet close to or located on the ground is the lower side, and the side far from the ground is the upper side. In addition, the terms "inner" and "outer" refer to the inside and outside of the corresponding structural contour. Additionally, terms such as "first" and "second" are only used to distinguish one element from another, and do not have sequentiality or importance.

[0049] In the description of the present disclosure, it should also be noted that unless otherwise clearly specified and limited, the terms "arranged", "connected", "linked", and "installed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0050] As Figures 1 to 10 shown, in the first aspect of the present disclosure, a housing 10 is provided. The housing 10 includes a cabinet door 100 and a cabinet body 200. An opening 11 is arranged on one side of the cabinet body 200. One end of the cabinet door 100 is movably connected to the cabinet body 200 and is adapted to open or close the opening 11. For example, one end of the cabinet door 100 is hinged above the opening 11 of the cabinet body 200, and the cabinet door 100 is configured as an up-and-down opening cabinet door 100.

[0051] Through the above solution, the cabinet door 100 and the cabinet body 200 are configured as an up-and-down opening cabinet door 100, so that when the cabinet door 100 is opened or closed, the area of the opening 11 of the cabinet body 200 will not be reduced. At the same time, since the other end of the cabinet door 100 can be connected to the cabinet body 200 to close the opening 11, there is no need to set up door posts at the opening 11 of the cabinet body 200 for the cabinet door 100 to connect, avoiding the space occupied by the door posts inside the cabinet body 200. Thus, the space inside the cabinet body 200 for accommodating the battery module can be increased by canceling the door posts, which is beneficial to increasing the volume of the battery module arranged in the housing 10 and enhancing the energy storage capacity of the energy storage cabinet.

[0052] It should be noted that the battery module can include a battery module and / or a battery pack, and both the battery module and the battery pack have battery cells inside. The movable connection manner between the cabinet door 100 and the cabinet body 200 includes but is not limited to hinged connection or sliding connection. As Figure 1 and Figure 5It shows that the cabinet door 100 and the cabinet body 200 adopt a hinged movable connection method. One end of the cabinet door 100 is hinged to the cabinet body 200 through a first hinge 140, and the first hinge 140 is located above the opening 11, so that the cabinet door 100 can be opened by rotating upward to expose the opening 11, and the cabinet door 100 can be closed by rotating downward to close the opening 11. Of course, when adopting a sliding connection movable connection method, a chute arranged in the height direction can be provided on the cabinet body 200, and the cabinet door 100 can be slid in the chute to realize that the cabinet door 100 slides upward to open the cabinet door 100 to expose the opening or the cabinet door 100 slides downward to close the cabinet door 100 and close the opening 11.

[0053] When the cabinet door 100 is hinged to the cabinet body 200, since the cabinet door 100 rotates upward when it is in the open state, after the cabinet door 100 is opened, the cabinet door 100 can form a plate-shaped shielding structure, which has a certain function of preventing rain and sun, so that the operator can stand under the shielding structure formed by the cabinet door 100 to operate the battery module in the cabinet body 200, and then the energy storage cabinet formed by the housing 10 can be used in an outdoor environment.

[0054] In addition, the housing 10 can be a part of the energy storage cabinet. In the drawings provided in this embodiment, only the frame structure of the cabinet body 200 in the housing 10 is shown. In actual application, a skin or a decorative board is also provided on the outer surface or the inner surface of the cabinet body 200, so as to use the frame structure as the installation basis for the skin or the decorative board, so that the surface of the cabinet body 200 can form a relatively closed structure, cooperate with the cabinet door 100 to form an energy storage cabinet, and form an accommodation cavity for accommodating the battery module inside. After that, multiple energy storage cabinets can be connected to form an energy storage device. Of course, when there are multiple housings 10, multiple housings 10 can be arranged side by side and connected together, and then a skin or a decorative board is provided to form an energy storage cabinet device. In this way, the accommodation cavities between multiple side-by-side arranged housings 10 can communicate with each other.

[0055] It should be noted that the opening of the cabinet body 200 is communicated with the accommodation cavity inside the cabinet body 200, and the accommodation cavity is used for placing the battery module.

[0056] In some alternative embodiments, the cabinet body 200 includes a first door body 110 and a second door body 120. The first end of the first door body 110 is hinged to the cabinet body 200, and the second end of the first door body 110 is hinged to the first end of the second door body 120, so that the cabinet door 100 is configured as a vertically foldable cabinet door 100.

[0057] The first door body 110 and the second door body 120 in the cabinet door 100 are folded up and down. After the cabinet door 100 is opened, the second door body 120 can be folded relative to the first door body 110 to shorten the opening length after the cabinet door 100 is opened. Thus, when the energy storage cabinets are in multiple columns, the gap between two adjacent columns of the housing 10 can be shortened, and then the gap between two columns of energy storage cabinets can be shortened, making the arrangement of the energy storage cabinets more compact. When the cabinet door 100 is closed, the first door body 110 and the second door body 120 are in the unfolded state.

[0058] It should be noted that when the gap between two adjacent columns of energy storage cabinets is large enough or there is only one column of energy storage cabinets, when the cabinet door 100 is opened, the second door body 120 may not be selectively folded relative to the first door body 110, that is, the first door body 110 and the second door body 120 remain in the unfolded state after the cabinet door 100 is opened. In this way, a larger shielding structure can be formed, having a larger shielding area. The first door body 110 is hinged to the cabinet body 200 through a first hinge member 140, and the first door body 110 is hinged to the second door body 120 through a second hinge member 150.

[0059] Since the energy storage cabinet formed by the housing 10 needs certain sealing requirements when used outdoors to ensure the normal operation of the battery module inside the energy storage cabinet. In view of this, in some alternative embodiments of the present disclosure, a first sealing structure 300 is provided on the cabinet door 100, and the first sealing structure 300 is adapted to seal a first gap 130 between the second end of the first door body 110 and the first end of the second door body 120. When the cabinet door 100 is in the closed state, the first sealing structure 300 seals the first gap 130 to prevent liquid (such as rainwater) or solid (such as dust) from entering the inside of the housing 10 from the first gap 130.

[0060] It should be noted that when the cabinet door 100 is in the open state and the first door body 110 and the second door body 120 are unfolded, the first sealing structure 300 can also seal the first gap 130 to prevent rainwater from dripping from the first gap 130 when the cabinet door 100 is a folding structure.

[0061] Regarding the specific structure of the first sealing structure 300, as Figures 2 to 4 shown, the first sealing structure 300 may include a first seal 310 and a second seal 320. Both the first seal 310 and the second seal 320 are adapted to be sealingly disposed in the first gap 130. The cabinet door 100 has an inner side surface adapted to close the opening 11, and the second seal 320 is closer to the inner side surface than the first seal 310. The first seal 310 and the second seal 320 can form a double-sealing effect at the first gap 130 to improve the sealing performance of the first gap 130 between the first door body 110 and the second door body 120.

[0062] The inner side here can also be understood as the surface of the cabinet door 100 facing the accommodation cavity or the surface constituting the accommodation cavity when the cabinet door 100 is in the closed state.

[0063] Of course, in other alternative embodiments, the first sealing structure 300 may also include only the first seal 310 or the second seal 320, and seal the first gap 130 through the first seal 310 or the second seal 320. Or, the first sealing structure 300 may further include another seal provided for sealing the first gap 130 to form a triple or more seal at the first gap 130. In this regard, the present disclosure does not make specific limitations.

[0064] It should be noted that the first seal 310 may be fixed on either the first door body 110 or the second door body 120, and the second seal 320 may be fixed on either the first door body 110 or the second door body 120. In this regard, the present disclosure does not make specific limitations.

[0065] In some alternative embodiments, both the first seal 310 and the second seal 320 may be elastic seals to achieve a better sealing effect through the deformation of the elastic seals. Of course, in other embodiments, the first seal 310 and the second seal 320 may also adopt rigid seals to achieve sealing by means of surface fitting contact sealing.

[0066] To improve the sealing effect of the first seal 310 and the second seal 320 on the first gap 130, as Figures 2 to 4 shown, the first seal 310 is adapted to be fixed to the second end of the first door body 110 and is adapted to be press-fitted and sealed with the first end of the second door body 120; the second seal 320 is adapted to be fixed to the first end of the second door body 120 and is adapted to be press-fitted and sealed with the second end of the first door body 110; wherein, when the cabinet door 100 is in the closed state, the position where the first seal 310 is press-fitted and sealed with the second door body 120 is lower than the position where the second seal 320 is press-fitted and sealed with the first door body 110.

[0067] Fix the first seal 310 at the second end of the first door body 110 so that there is a seal between the first seal 310 and the second end of the first door body 110. The gap between the first seal 310 and the first end of the second door body 120 forms the first gap segment of the first gap 130. Fix the second seal 320 at the first end of the second door body 120 so that there is a seal between the second seal 320 and the first end of the second door body 120. The gap between the second seal 320 and the second end of the first door body 110 forms the second gap segment of the partial first gap 130. And by setting the position where the first seal 310 is crimped and sealed with the second door body 120 to be lower than the position where the second seal 320 is crimped and sealed with the first door body 110, so that the height where the first gap segment is located is lower than the height where the second gap segment is located. Since liquids or solids generally do not have the ability to move upward by their own gravity, therefore, liquids or solids outside the housing 10 cannot pass through the first gap segment and the second gap segment and enter the cabinet body 200. Therefore, the sealing effect at the first gap 130 is further improved.

[0068] As Figures 2 to 4 shown, in some alternative embodiments, the first sealing structure 300 further includes a first convex portion 340. The first convex portion 340 is provided and protrudes from the end face of the first end of the second door body 120. The second seal 320 is disposed on the first convex portion 340. By providing the first convex portion 340, the first convex portion 340 can protrude from the end face of the second end of the second door body 120. After the liquid or solid enters the first gap 130, it needs to move upward and cross the first convex portion 340 before it is possible to reach the accommodation cavity. Thus, the first convex portion 340 can improve the sealing effect on the first gap. Even if the seal of the second seal 320 fails, the first convex portion 340 still has a certain sealing effect.

[0069] In some alternative embodiments, the first convex portion 340 and the second door body 120 are integrally formed to improve the connection strength and the sealing effect between the first convex portion 340 and the second door body 120. Of course, in other embodiments, the first convex portion 340 and the second door body 120 can also be connected by other connection methods such as bolt connection and bonding. The second seal 320 can be fixed on the first convex portion 340 in a detachable manner, such as by snap connection or bolt connection.

[0070] To further improve the sealing effect on the first gap 130, as Figures 2 to 4As shown, in some alternative embodiments, the first sealing structure 300 further includes a second convex portion 330. The second convex portion 330 is provided and protrudes from the end face of the second end of the first door body 110. The second convex portion 330 cooperates with the first convex portion 340 to make the first gap 130 have an inclined gap section 131 that extends obliquely upward from the outside to the inside. The first seal 310 is disposed on the second convex portion 330, and the second seal 320 is disposed on the first convex portion 340.

[0071] Providing the second convex portion 330 can cooperate with the first convex portion 340 to form an inclined gap section 131 that extends obliquely upward from the outside to the inside, and this inclined gap section 131 can prevent liquids or solids from entering the interior of the cabinet body 200. Even when the first seal 310 and / or the second seal 320 fails to seal, this inclined gap section 131 still exists.

[0072] It should be noted that here, from the outside to the inside refers to from the outer side of the cabinet door 100 to the inner side of the cabinet door 100. The outer side of the cabinet door 100 and the inner side of the cabinet door 100 are oppositely arranged.

[0073] In some alternative embodiments, the second convex portion 330 is integrally formed with the first door body 110 to improve the connection strength and sealing effect between the second convex portion 330 and the first door body 110. Of course, in other embodiments, the second convex portion 330 can also be fixed to the first door body 110 by means such as welding or bolt connection. The first seal 310 can be fixed to the second convex portion 330 in a detachable manner, such as by snap connection or bolt connection.

[0074] As Figure 4 shown, in some alternative embodiments, the second convex portion 330 has a first mounting surface 331, a first inclined surface 332, and a first crimping surface 333 that are sequentially connected from the outside to the inside. The first convex portion 340 has a second crimping surface 341, a second inclined surface 342, and a second mounting surface 343 that are sequentially connected from the outside to the inside. Among them, the first seal 310 is fixed to the first mounting surface 331 and is adapted to be crimped and sealed with the second crimping surface 341. The second seal 320 is fixed to the second mounting surface 343 and is adapted to be crimped and sealed with the first crimping surface 333. The first inclined surface 332 and the second inclined surface 342 are oppositely arranged to construct the inclined gap section 131.

[0075] By providing an installation base for the first seal 310 by setting the first installation surface 331, the first seal 310 is crimped and sealed with the second crimping surface 341, and by setting the second installation surface 343 as the installation base for the second seal 320, the second seal 320 is crimped and sealed with the first crimping surface 333, it can be ensured that the sealing positions of the first seal 310 and the first crimping surface 333 and the sealing positions of the second seal 320 and the second crimping surface 341 are spaced apart by the inclined gap section 131. Even when the first seal 310 fails to seal, the liquid cannot flow directly onto the second seal 320 along the first seal 310.

[0076] As Figures 1 to 3 shown, in some alternative embodiments, the cabinet door 100 is provided with a second sealing structure 400, and the second sealing structure 400 is adapted to seal the first gap 130 between the first door body 110 and the second door body 120. The second sealing structure 400 includes a first panel 410, and the first panel 410 includes a first part 411 and a second part 412. The first part 411 is adapted to be disposed on the outer side surface of the first door body 110, and the second part 412 is adapted to be in contact with the outer side surface of the second door body 120.

[0077] Designed in this way, when the first door body 110 and the second door body 120 are folded, the first panel 410 is disposed on the first door body 110 through the first part 411 and moves with the first door body 110. When the cabinet door 100 is in the closed state, the second part 412 of the first panel 410 is in contact with the outer side surface of the second door body 120 to achieve sealing, so that the first panel 410 can block the connection position between the first door body 110 and the second door body 120, playing a role in blocking and sealing the first gap 130, reducing the probability of liquid and solid entering the first gap 130, and improving the sealing effect on the first gap 130.

[0078] It should be noted that the outer side surface of the first door body 110 is also a part of the outer side surface of the cabinet door 100; the inner side surface of the first door body 110 is also a part of the inner side surface of the cabinet door 100. Also, the outer side surface of the second door body 120 is also a part of the outer side surface of the cabinet door 100; the inner side surface of the second door body 120 is also a part of the inner side surface of the cabinet door 100. In addition, when the cabinet door 100 is provided with both the first sealing structure 300 and the second sealing structure 400, the sealing effect on the first gap 130 can be improved.

[0079] Optionally, the first panel 410 is a decorative panel. Using the decorative panel of the cabinet door 100 as the first panel 410 enables the first panel 410 to serve two purposes, not only achieving the effect of blocking and sealing the first gap 130, but also improving the aesthetics of the cabinet door 100.

[0080] As Figure 2 andFigure 3 As shown, in some alternative embodiments, a second panel 420 is provided on the outer side of the second door body 120. When the first panel 410 is attached to the outer side wall of the second door body 120, one end of the first panel 410 is in surface contact with one end of the second panel 420, so that the second panel 420 cooperates with the first panel 410 to improve the sealing effect on the first gap 130.

[0081] Optionally, the second panel 420 can also be a decorative panel.

[0082] As Figures 5 to 10 shown, in some alternative embodiments, the housing 10 is provided with a third sealing structure 500. When the cabinet door 100 is in the closed state, the third sealing structure 500 is adapted to seal the gap between the cabinet body 200 and the cabinet door 100 (hereinafter referred to as the second gap). After the third sealing structure 500 seals the second gap, it can prevent liquids and solids from entering the cabinet body 200 through the second gap, further improving the sealing effect of the housing 10.

[0083] Optionally, as Figure 6 and Figure 7 shown, the third sealing structure 500 includes a third seal 510 and a fourth seal 520. The third seal 510 is arranged to extend along the length or width direction of the opening 11, and the fourth seal 520 is configured in a U-shaped structure. When the cabinet door 100 is in the closed state, the two ends of the third seal 510 are hermetically connected to the two ends of the fourth seal 520 to form an annular structure and are adapted to seal the second gap between the cabinet body 200 and the cabinet door 100. The annular structure can ensure the sealing performance between the cabinet body 200 and the cabinet door 100.

[0084] It should be noted that the extension of the third seal 510 along the length or width direction of the opening 11 is determined according to the size of the opening 11. When the dimension of the opening 11 in the height direction of the cabinet body 200 is greater than the dimension of the opening 11 in the direction perpendicular to the height direction of the cabinet body 200, the third seal 510 extends along the width direction of the opening 11. When the dimension of the opening 11 in the height direction of the cabinet body 200 is less than the dimension of the opening 11 in the direction perpendicular to the height direction of the cabinet body 200, the third seal 510 extends along the length direction of the opening 11. It can also be understood that the third seal 510 extends generally along a direction perpendicular to the height direction of the cabinet body 200. The third seal 510 and the fourth seal 520 can both be provided on the cabinet door 100, or both be provided on the cabinet body 200, or one of the third seal 510 and the fourth seal 520 can be provided on the cabinet door 100 and the other on the cabinet body 200. In this regard, the present disclosure does not make specific limitations. The annular structure formed by the third seal 510 and the third seal 510 can be located outside the opening of the cabinet door 100, that is, the opening of the cabinet door 100 is located within the area enclosed by the annular structure. In this way, when the cabinet door 100 is in the closed state, through the sealing between the third sealing structure 500 and the cabinet door 100 and the cabinet body 200, it is possible to isolate the opening of the cabinet door 100 from the outside, achieving the effect of preventing liquid or solids from entering the cabinet body 200 through the second gap. Of course, in other embodiments, the annular structure formed by the third seal 510 and the third seal 510 can also be located on the inner side wall of the opening 11, and the accommodation cavity is sealed by inserting the cabinet door 100 into the opening 11.

[0085] Such as Figures 5 to 7As shown, in some alternative embodiments, a first mounting member 160 extending along the length or width direction of the opening 11 is provided on the inner side surface of the cabinet door 100. A first drainage groove 161 with an upward-facing notch is formed on the first mounting member 160. The above-mentioned third sealing member 510 is installed on the side of the first mounting member 160 away from the first door body 110. The top of the third sealing member 510 is not lower than the notch of the first drainage groove 161. When the cabinet door 100 is in the closed state, the third sealing member 510 is adapted to press and seal the gap between the third sealing member 510 and the corresponding part of the cabinet body 200. Providing the first mounting member 160 on the housing 10 can provide a mounting base for the third sealing member 510, enabling the third sealing member 510 to be fixedly installed with the cabinet door 100 by being fixed on the first mounting member 160. By arranging the third sealing member 510 on the side of the first mounting member 160 away from the cabinet door 110 and setting the top of the third sealing member 510 to be not lower than the notch of the first drainage groove 161 formed on the first mounting member 160, when the third sealing member 510 is pressed and sealed with the cabinet body 200, the liquid entering from the gap between the cabinet door 100 and the cabinet body 200 will flow into the first drainage groove 161 through the third sealing member 510, and then the first drainage groove 161 will divert the liquid to other positions for discharge. For example, the liquid is diverted to the drainage groove 231 as shown in Figure 8 . At the same time, it also avoids the formation of a concave structure between the top of the third sealing member and the first mounting member 160 caused by the third sealing member being lower than the notch of the first drainage groove 161, thereby preventing rainwater from flowing smoothly into the first drainage groove 161.

[0086] It should be noted that when the cabinet door 100 includes a first door body 110 and a second door body 120, and the first end of the first door body 110 is hinged to the cabinet body 200 and the second end of the first door body 110 is hinged to the first end of the second door body 120, the above-mentioned first mounting member 160 is provided on the inner side surface of the first door body 110. The third sealing member 510 can be fixed to the first mounting member 160 by means of snap connection. Specifically, as shown in Figure 7 , the third sealing member 510 can be snap-connected to the side of the first mounting member 160 away from the cabinet door 110. Of course, the third sealing member 510 can also be fixed to the first mounting member 160 by means of bonding or bolt pressing.

[0087] It should be noted that the gap between the third sealing member 510 and the corresponding part of the cabinet body 200 refers to the gap between the part of the cabinet door 100 provided with the third sealing member 510 and the corresponding part of the cabinet body 200.

[0088] As shown in Figures 5 to 7As shown, in some alternative embodiments, the cabinet body 200 has a cross beam 210 adapted to be sealingly crimped with a third seal 510. The cross beam 210 is near the upper end of the cabinet body 200. A second diversion groove 221 is provided on the cabinet body 200. The opening of the second diversion groove 221 faces upward and is located below the crimping and sealing position between the cross beam 210 and the third seal 510. The second diversion groove 221 receives the liquid flowing down due to seal failure between the third seal 510 and the cabinet body 200, preventing this part of the liquid from directly dripping inside the cabinet body 200.

[0089] Optionally, the cabinet body 200 is provided with a second mounting member 220, and the second diversion groove 221 is formed on the second mounting member 220. Of course, in other embodiments, the second diversion groove 221 can also be directly formed on the cabinet body 200.

[0090] As Figure 7 shown, in some alternative embodiments, a first diversion plate 211 extends downward from the lower end of the cross beam 210. The projection of the lower end of the first diversion plate 211 in the vertical direction is located within the notch of the second diversion groove 221. At least a part of the third seal 510 is adapted to be sealingly crimped with the first diversion plate 211. The first diversion plate 211 can divert the liquid, so that when the seal fails between the third seal 510 and the cabinet body 200, the leaked liquid can be diverted into the second diversion groove 221, further preventing the liquid from flowing into the cabinet body 200 along the surface of the cross beam 210.

[0091] As Figure 7 shown, in some alternative embodiments, an inclined second diversion plate 170 is provided on the cabinet door 100. The first end of the second diversion plate 170 is connected to the cabinet door 100, and the second end of the second diversion plate 170 extends in a direction away from the cabinet door 100. When the cabinet door 100 is in the closed state, the position of the second end of the diversion plate is lower than the first end. The second diversion plate 170 is used to divert the liquid into the notch of the second diversion groove 221.

[0092] It should be noted that when the cabinet door 100 includes a first door body 110 and a second door body 120, and the first end of the first door body 110 is hinged to the cabinet body 200 and the second end of the first door body 110 is hinged to the first end of the second door body 120, the second diversion plate 170 is also provided on the first door body 110 to relatively fix the first door body 110 and the first mounting member 160.

[0093] Optionally, the first diversion plate 211 and the second diversion plate 170 are arranged oppositely, and a flow path for the liquid is defined between the first diversion plate 211 and the second diversion plate 170, so that the leaked liquid after the third seal 510 fails can be guided into the second diversion groove 221 through this flow path.

[0094] AsFigure 10 As shown, in some alternative embodiments, the fourth seal 520 is disposed outside the opening 11 of the cabinet body 200. Both ends of the fourth seal 520 are adapted to be connected to both ends of the third seal 510 to form an annular structure for sealing the second gap between the cabinet body 200 and the cabinet door 100. At least one side of the cabinet door 100 is provided with a water guide plate 230. The water guide plate 230 is spaced from the fourth seal 520 and located outside the fourth seal 520. The water guide plate 230, together with a part of the fourth seal 520 and the cabinet body 200, constructs a drainage groove 231. The first diversion groove 161 is communicated with the drainage groove 231, and / or the second diversion groove 221 is communicated with the drainage groove 231.

[0095] When the cabinet door 100 is in the closed state, both ends of the fourth seal 520 are connected to both ends of the third seal 510 to form an annular structure, which is press-fitted and sealed between the cabinet door 100 and the cabinet body 200, thereby realizing the sealing of the second gap between the cabinet door 100 and the cabinet body 200 and preventing liquid or solid from entering the cabinet body 200 through the second gap. The drainage groove 231 can receive the liquid in the first diversion groove 161 and / or the second diversion groove 221 to discharge the liquid outside the energy storage cabinet.

[0096] It should be noted that both the upper end and the lower end of the drainage groove 231 are open ends. The liquid flowing out of the first diversion groove 161 and / or the second diversion groove 221 can enter the drainage groove 231 from the upper end opening of the drainage groove 231 and then directly flow to the installation foundation of the energy storage cabinet, such as the ground, from the lower end of the drainage groove 231. Of course, the lower end of the drainage groove 231 can also be communicated with other drainage structures to discharge the liquid through other drainage structures. The communication position between the first diversion groove 161 and the drainage groove 231 can be at the end of the first diversion groove 161 or at a position other than the end (for example, opening a hole at the bottom of the groove near the end of the first diversion groove 161). For the communication position between the second diversion groove 221 and the drainage groove 231, it can be at the end of the first diversion groove 161 or at a position other than the end (for example, opening a hole at the bottom of the groove near the end of the second diversion groove 221).

[0097] As Figure 8 and Figure 10 As shown, in some alternative embodiments, a water blocking strip 240 is provided on at least one side of the open end of the cabinet body 200. When the cabinet door 100 is in the closed state, the water blocking strip 240 is used to block the gap between the cabinet door 100 and the corresponding side wall of the cabinet body 200. The water blocking strip 240 can block the rainwater or splashed liquid floating on the side of the energy storage cabinet to prevent this part of the rainwater or splashed liquid from entering the second gap, thereby improving the sealing effect of the second gap to a certain extent.

[0098] Optionally, when the cabinet door is in the closed state, the side wall of the cabinet door 100 fits against the water baffle 240 to further improve the blocking effect on rainwater or splashing liquid.

[0099] In a second aspect of the present disclosure, an energy storage cabinet is provided. The energy storage cabinet includes a battery module and the above-mentioned housing 10, and the battery module is disposed inside the housing. The energy storage cabinet has all the beneficial effects of the above-mentioned housing, and the present disclosure will not elaborate on this.

[0100] In some alternative embodiments, the battery cells of the battery module are adapted to be in direct contact with the coolant of the battery module, so that the battery cells can directly exchange heat with the coolant for cooling.

[0101] It should be noted that a pipeline structure can be provided inside the energy storage cabinet. The pipeline structure can be in communication with the inside of the battery module. A flowable coolant is provided inside the pipeline structure, and the coolant can flow into the battery module so that the battery cells inside the battery module can exchange heat by contacting the coolant. After heat exchange, the coolant can also flow out of the battery module. There are various ways of heat exchange between the battery cells and the coolant. For example, the battery cells inside the battery module are adapted to be in direct contact with the coolant inside the battery module and be immersed or sprayed with the coolant. That is, the heat exchange method of the battery cells here can be heat exchange by immersion of the coolant or heat exchange of the battery cells by spraying the coolant onto the surface of the battery cells.

[0102] In a third aspect of the present disclosure, an energy storage device is provided. The energy storage device includes a plurality of energy storage cabinets.
