[0046] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0047] Energy storage equipment, such as liquid-cooled outdoor energy storage cabinets, currently employs the following drainage measures: a funnel-shaped or inclined partition with an angle to the horizontal plane is installed at the bottom of the cabinet, a floor drain is installed at the lowest point of the partition, and a water pipe corresponding to the electrical compartment is fixed at the floor drain. Water in the electrical compartment is then guided through the water pipe to the floor drain inside the cabinet and discharged through the floor drain.

[0048] Because the door frame sealing strips inside the liquid-cooled energy storage outdoor cabinet are arranged in a continuous ring, water inside the cabinet can only drain through the floor drain. However, when the floor drain becomes clogged, water inside the cabinet (such as condensate or leaked coolant) cannot drain out, posing a short-circuit risk to the electrical components inside the cabinet. Furthermore, the floor drains are generally made of pure copper and are designed to prevent backflow, which is typically expensive.

[0049] This application provides an energy storage device that can solve the problems in the aforementioned related technologies.

[0050] Figure 1 This is a schematic diagram of an energy storage device structure provided in an embodiment of this application. Please refer to it. Figure 1 One embodiment of this application provides an energy storage device 000, including: a cabinet 010, a partition 020, and a cover 030.

[0051] The cabinet 010 has a storage compartment C1 and a first opening K that communicates with the storage compartment C1.

[0052] The partition 020 is fixed inside the receiving chamber C1. The side of the partition 020 facing the top of the cabinet 010 has a liquid collection tank 0211, and the edge portion of the partition 020 facing the first opening K has a first flow channel L1, with the liquid collection tank 0211 communicating with the first flow channel L1.

[0053] The cover plate 030 is connected to one side of the cabinet body 010 where the first opening K is located, and covers the first opening K.

[0054] The containment chamber C1 has a second flow channel L2 at the edge of the first opening K. The extension direction of the second flow channel L2 intersects the extension direction of the first flow channel L1, and the end of the second flow channel L2 is connected to the end of the first flow channel L1.

[0055] To clearly illustrate the liquid collection tank 0211, the first flow channel L1, and the second flow channel L2 in the energy storage device 000, please refer to... Figure 2 , Figure 2 yes Figure 1 Enlarged structural diagram of point A in the energy storage device.

[0056] In summary, since the partition has a liquid collection tank on the side facing the top of the cabinet, and a first flow channel on the edge of the partition facing the first opening, the liquid collection tank is connected to the first flow channel. The edge of the containment chamber facing the first opening has a second flow channel, the extension direction of the second flow channel intersects with the extension direction of the first flow channel, and the end of the second flow channel is connected to the end of the first flow channel. Thus, the liquid generated in the containment chamber can be collected through the liquid collection tank on the partition, and the collected liquid can flow to the outside through the first and second flow channels in sequence, thereby realizing the drainage operation of the liquid in the containment chamber. The energy storage device of this application does not require the introduction of special pipelines for drainage; the drainage flow channel can be formed solely through the cooperation of the partition and the cabinet, effectively simplifying the structure of the energy storage device and solving the problem of structural complexity caused by drainage.

[0057] Figure 3 This is a schematic diagram of a partition structure provided in an embodiment of this application. Please refer to it. Figure 3 In some feasible implementations, the end of the liquid collection tank 0211 facing the first opening K is the open end C2, and the liquid collection tank 0211 on the partition 020 is connected to the first flow channel L1 through the open end C2.

[0058] The open end C2 of the liquid collection tank 0211 facing the first opening K facilitates the timely discharge of the liquid collected in the liquid collection tank 0211 to the first flow channel L1, and then to the outside through the second flow channel L2, thereby realizing the drainage of the containment chamber C1 and ensuring the electrical safety of the energy storage device 000.

[0059] For example, the liquid collection tank 0211 has a first sidewall 0212 connected to each other, two oppositely distributed second sidewalls 0213, and a bottom wall 0214. The two second sidewalls 0213 and the bottom wall 0214 form an open end C2 on the side near the first opening K, and the first sidewall 0212 is disposed opposite to the open end C2.

[0060] Among them, the first sidewall 0212 and the two second sidewalls 0213 are all inclined relative to the bottom wall 0214.

[0061] The first sidewall 0212 and the second sidewall 0213 are inclined, so that the liquid collected on the sidewall can flow quickly to the bottom wall 0214, and then flow to the first flow channel L1 through the bottom wall 0214. In this way, the drainage efficiency can be accelerated, and the electrical compartment C12 is kept in a relatively dry environment so that the components inside the electrical compartment C12 can operate normally.

[0062] The bottom wall 0214 in the liquid collection tank 0211 can be distributed parallel to or inclined relative to the bottom of the cabinet 010. When the bottom wall 0214 is inclined relative to the bottom of the cabinet 010, the side of the bottom wall 0214 away from the first flow channel L1 is higher than the side of the bottom wall 0214 close to the first flow channel L1. In this way, the inclined bottom wall 0214 can further accelerate the speed at which the liquid in the liquid collection tank 0211 flows to the first flow channel L1, thereby improving the drainage efficiency.

[0063] In other feasible embodiments, the end of the liquid collection tank 0211 facing the first opening K can also be a closed end, and a guide hole is opened on the side wall of the liquid collection tank 0211 at the closed end. The liquid collection tank 0211 is connected to the first flow channel L1 through the guide hole to realize the drainage of the liquid collection tank 0211.

[0064] In some feasible implementations, the partition 020 divides the housing C1 into a battery compartment C11 and an electrical compartment C12, with the electrical compartment C12 being closer to the top of the cabinet 010 than the battery compartment C11.

[0065] The battery compartment C11 has a second flow channel L2 at the edge portion facing the first opening K.

[0066] It is understood that the liquid discharged from the energy storage device 000 of this application mainly includes condensate in the electrical compartment C12 and leaked coolant. The drainage channels refer to the first channel L1 on the partition 020 and the second channel L2 on the cabinet 010 at the battery compartment C11.

[0067] Figure 4 This is a schematic diagram of another partition structure provided in an embodiment of this application. Please refer to it. Figure 4 In one feasible embodiment, the partition 020 includes a partition body 021 and a first flow guide 022. The side of the partition body 021 facing the electrical compartment C12 has a liquid collection tank 0211. The first flow guide 022 is fixedly connected to the edge of the partition body 021 facing the first opening K, and the first flow guide 022 has a first flow channel L1.

[0068] Figure 5 This is a schematic diagram of another energy storage device structure provided in an embodiment of this application. Figure 6 yes Figure 5 The enlarged structural diagram of section B of the energy storage device is shown below. For a clearer view of the structure of the first flow guide 022, please refer to [the diagram / reference needed]. Figure 6For example, the first guide member 022 includes a first folded edge B1, a second folded edge B2, and a third folded edge B3. The first folded edge B1 and the third folded edge B3 are arranged parallel to each other and opposite to each other. The second folded edge B2 is located between the first folded edge B1 and the third folded edge B3, and both sides of the second folded edge B2 are fixedly connected to one side of the first folded edge B1 and the third folded edge B3, respectively. The side of the first folded edge B1 facing away from the second folded edge B2 is fixedly connected to the edge of the partition body 021 facing the first opening K.

[0069] The first fold B1, the second fold B2, and the third fold B3 form the first flow channel L1.

[0070] The first flow guide 022 is formed by the first folded edge B1, the second folded edge B2 and the third folded edge B3 to form the first flow channel L1. The structure is simple and easy to process.

[0071] The first folded edge B1 in the first guide member 022 can be independently set relative to the side wall of the partition body 021 facing the first opening K, and the first folded edge B1 and the side wall of the partition 020 facing the first opening K can be connected by welding. Alternatively, the first folded edge B1 can also be directly used as the side wall of the partition body 021 facing the first opening K, thus simplifying the structure of the partition 020 and reducing the material cost of the partition 020.

[0072] In some feasible embodiments, the energy storage device 000 further includes a second flow guide 011. The second flow guide 011 is fixedly connected to the edge portion of the battery compartment C11 facing the first opening K, that is, the second flow guide 011 is fixedly connected to the side wall of the cabinet 010 corresponding to the battery compartment C11 on the side of the first opening K.

[0073] The second flow guide 011 has a second flow channel L2, one end of which is connected to the end of the first flow channel L1, and the other end of which is connected to the outside.

[0074] For example, please refer to Figure 6 The second flow guide 011 includes a fourth folded edge B4, a fifth folded edge B5, and a sixth folded edge B6. The fourth folded edge B4 and the sixth folded edge B6 are parallel and opposite to each other. The fifth folded edge B5 is located between the fourth folded edge B4 and the sixth folded edge B6, and both sides of the fifth folded edge B5 are fixedly connected to one side of the fourth folded edge B4 and the sixth folded edge B6, respectively. The side of the fourth folded edge B4 facing away from the fifth folded edge B5 is fixedly connected to the edge of the battery compartment C11 facing the first opening K.

[0075] The fourth fold B4, the fifth fold B5, and the sixth fold B6 form the second flow channel L2.

[0076] The second flow guide 011 is formed by the fourth fold B4, the fifth fold B5 and the sixth fold B6 to form the second flow channel L2. The structure is simple and easy to process.

[0077] The fourth fold B4 in the second flow guide 011 can be independently set relative to the side wall of the battery compartment C11 facing the first opening K, and the fourth fold B4 and the side wall of the battery compartment C11 facing the first opening K can be connected by welding. Alternatively, the fourth fold B4 can be directly used as the side wall of the battery compartment C11 facing the first opening K, thus simplifying the structure of the second flow guide 011 and reducing the material cost of the second flow guide 011.

[0078] In some feasible embodiments, the energy storage device 000 further includes a third flow guide 012. The third flow guide 012 is located between the end of the first flow guide 022 and the end of the second flow guide 011, and the third flow guide 012 has a third flow channel L3, the two ends of which are respectively connected to the end of the first flow channel L1 and the end of the second flow channel L2.

[0079] By setting the third guide component 012, the liquid in the first flow channel L1 of the first guide component 022 is guided into the second flow channel L2 of the second guide component 011, making the drainage operation smoother and helping to ensure the sealing of the battery compartment C11.

[0080] For example, please refer to Figure 7 , Figure 7 for Figure 1 The enlarged structural diagram of point A of the energy storage device shows that, in order to better ensure the drainage and the sealing of the battery compartment C11 during drainage, the third guide component 012 includes: the seventh fold B7 and the eighth fold B8.

[0081] Among them, one side of the seventh fold B7 is connected to the second fold B2, and the other side of the seventh fold B7 is connected to the fifth fold B5. One side of the eighth fold B8 is connected to the third fold B3, and the other side of the eighth fold B8 is connected to the sixth fold B6.

[0082] For example, a second guide member 011 is provided on each side of the first guide member 022, and correspondingly, a third guide member 012 is provided on each side of the first guide member 022. In this way, after the liquid in the collection tank 0211 flows into the first flow channel L1, it can flow to both sides of the first flow channel L1 and be discharged outside the cabinet 010 through the third flow channel L3 and the second flow channel L2 on both sides. That is, a symmetrical double-drainage flow channel is formed inside the energy storage device 000, which ensures both drainage efficiency and drainage reliability.

[0083] Figure 8This is a partial structural diagram of an energy storage device provided in an embodiment of this application. Figure 8 The main structures shown are the liquid collection tank 0211, the first flow channel L1, the second flow channel L2, and the third flow channel L3. Figure 8 The arrows in the diagram indicate the flow direction of the liquid in the electrical compartment C12. Specifically, the liquid flows through the second side wall 0213 to the bottom wall 0214, then through the bottom wall 0214 to the first flow channel L1, and then through the third flow channel L3 and the second flow channel L2 to be discharged outside the cabinet 010.

[0084] Please refer to Figure 5 In some feasible embodiments, the energy storage device 000 further includes a first sealing part 040. The first sealing part 040 is located at the edge of the battery compartment C11 facing the first opening K, the first sealing part 040 abuts against the side of the cover plate 030 facing the cabinet 010, and the first sealing part 040 is annular, and the first sealing part 040 is at least attached to the third folded edge B3 and the sixth folded edge B6.

[0085] The first sealing part 040 better ensures the airtightness of the battery compartment C11, guaranteeing the normal operation of the structure within the battery compartment C11. For example, the first sealing part 040 is an annular silicone sealing ring.

[0086] by Figure 5 For example, two second flow guides 011 are distributed on the left and right side walls of the cabinet 010 on the side where the first opening K is located. In order to fully ensure the sealing of the battery compartment C11, a fourth flow guide 013 is provided on the edge of the battery compartment C11 facing the first opening K and opposite to the first flow guide 022. The two sides of the fourth flow guide 013 are respectively connected to the second flow guides 011 on both sides.

[0087] The structure of the fourth guide member 013 is similar to that of the second guide member 011. For example, it also has three folded edges. A structure similar to that of the third guide member 012 can also be provided between the fourth guide member 013 and the second guide member 011 to connect the fourth guide member 013 and the second guide member 011, or the fourth guide member 013 can extend directly to the end of the second guide member 011 to contact and connect with the second guide member 011.

[0088] The second flow guide 011, the third flow guide 012 and the fourth flow guide 013 can be integrated with the cabinet 010. For example, the second flow guide 011, the third flow guide 012 and the fourth flow guide 013 can be formed by sheet metal stamping at the corresponding positions of the cabinet 010.

[0089] For example, the second guide member 011, the third guide member 012 and the fourth guide member 013 are connected to form a U-shaped or approximately U-shaped frame structure, and the U-shaped or approximately U-shaped frame structure is connected to the first guide member 022 to form a rectangular or approximately rectangular frame structure.

[0090] Correspondingly, the annular first sealing part 040 is a rectangular or approximately rectangular sealing part. The first sealing part 040 is connected to the third folded edge B3, the sixth folded edge B6, the eighth folded edge B8, etc., and abuts against the cover plate 030 to achieve sealing of the battery compartment C11 on the first opening K side.

[0091] In this embodiment, the second flow channel L2 is a hidden flow channel, which enables the energy storage device 000 to have a simple and compact structure without affecting the product appearance.

[0092] The connection principle between the first sealing part 040 and the first guide member 022, the second guide member 011, the third guide member 012, and the fourth guide member 013 is the same. Therefore, the connection method of the first sealing part 040 is illustrated by taking the connection between the first sealing part 040 and the first guide member 022 as an example. Please refer to... Figure 9 , Figure 9 This is a partial structural diagram of another energy storage device provided in the embodiment of this application. According to the cross-section of the first sealing part 040, the first sealing part 040 is provided with a hanging groove on the side away from the cover plate 030. The first sealing part 040 is hung with the third folded edge B3 in the first guide member 022 through the hanging groove.

[0093] Please refer to Figure 5 In some feasible embodiments, the energy storage device 000 further includes a second sealing part 050, which is located at the edge of the electrical compartment C12 facing the first opening K, and the second sealing part 050 abuts against the side of the cover plate 030 facing the cabinet 010.

[0094] The second sealing part 050 includes a first sealing section 051 and two oppositely distributed second sealing sections 052. The two ends of the first sealing section 051 are respectively connected to the first ends of the two second sealing sections 052, and the first guide member 022 is distributed between the second ends of the two second sealing sections 052.

[0095] The second sealing section 050, through the first sealing section 051 and two opposing second sealing sections 052, forms an inverted U-shaped or near-U-shaped sealing strip. This strip abuts against the cover plate 030 and is clamped between the back panel and the cabinet 010 to ensure a seal within the electrical compartment C12. The U-shaped or near-U-shaped sealing strip creates a clearance at the open end C2 of the liquid collection tank 0211, allowing liquid in the liquid collection tank 0211 to flow through the open end C2 to the first flow channel L1.

[0096] Figure 10 yes Figure 5 Please refer to the enlarged structural diagram of point C of the energy storage device. Figure 10 The electrical compartment C12 has a first bend 014, a second bend 015, and a third bend 016 fixed on the edge facing the first opening K.

[0097] The first bending portion 014 corresponds to the first sealing section 051, the second bending portion 015 corresponds to the second sealing section 052, and the third bending portion 016 is located between the adjacent first bending portion 014 and the second bending portion 015. The two sides of the third bending portion 016 are respectively fixedly connected to one side of the adjacent first bending portion 014 and one side of the second bending portion 015.

[0098] The second sealing part 050 can be connected to the bent edge of the first bent part 014 and the second bent part 015 on the side away from the cabinet 010.

[0099] Figure 11 This is a schematic diagram of another energy storage device structure provided in the embodiments of this application. Please refer to it. Figure 11 The energy storage device 000 also includes: battery pack 060, liquid cooler 070 and control box 080.

[0100] The battery packs 060 consist of multiple units, stacked within the battery compartment C11. The liquid cooler 070 and control box 080 are located within the electrical compartment C12. The liquid cooler 070 removes heat generated by the battery packs 060 through liquid circulation, while the control box 080 precisely controls and schedules the charging and discharging process of the battery packs 060 by monitoring parameters such as charge level, temperature, and voltage.

[0101] Figure 12 yes Figure 11 The enlarged structural diagram of the energy storage device at point D shows the first sealing part 040 installed on the side of the battery compartment C11 facing the first opening K and the second sealing part 050 installed on the side of the electrical compartment C12 facing the first opening K.

[0102] Figure 13 This is a schematic diagram of another energy storage device structure provided in the embodiments of this application. Please refer to it. Figure 13 In some feasible implementations, the energy storage device 000 also includes a base 090, which is connected to the bottom of the cabinet 010.

[0103] The height of the bottom of the cabinet 010 can be raised by the base 090, so that when the energy storage device 000 is actually used, the end of the second flow channel L2 away from the first flow channel L1, that is, the end of the second flow channel L2 near the bottom of the cabinet 010, can be spaced apart from the surface (e.g., the ground) supporting the energy storage device 000 through the base 090. In this way, the smooth flow of the second flow channel L2 can be ensured, and the port of the second flow channel L2 can be prevented from being blocked.

[0104] For example, the base 090 has a forkhole 091 to facilitate the transport of the energy storage device 000 by a forklift.

[0105] Figure 14 This is a partial internal structure diagram of an energy storage device provided in an embodiment of this application. Please refer to it. Figure 14 In some feasible implementations, multiple longitudinal beams 017 are fixed inside the cabinet 010. The multiple longitudinal beams 017 are distributed between the bottom and top of the cabinet 010, and the multiple longitudinal beams 017 are located on the side wall near the cabinet 010.

[0106] One side of the longitudinal beam 017 can be connected to the top of the cabinet 010, and the other side can be connected to the bottom of the cabinet 010. The peripheral edge of the partition 020 can be sealed and welded to multiple longitudinal beams 017 to ensure the airtightness of the adjacent battery compartment C11 and electrical compartment C12.

[0107] Figure 15 This is a schematic diagram of an energy storage device structure provided in another embodiment of this application. Please refer to it. Figure 15 In some feasible implementations, the cabinet 010 also has a second opening communicating with the containment chamber C1, and the second opening and the first opening K are distributed relative to each other.

[0108] The energy storage device also includes: cabinet door 0100. Cabinet door 0100 is connected to and covers the side of cabinet body 010 where the second opening is provided.

[0109] The cabinet door 0100 has an air inlet 0101 that connects to the electrical compartment C12, and the cover plate 030 has an air outlet 031 that connects to the electrical compartment C12.

[0110] An airflow channel is formed by the air inlet 0101 and the air outlet 031, which facilitates heat dissipation for the electrical compartment C12 and provides a good operating environment for the electrical compartment C12.

[0111] In summary, since the partition has a liquid collection tank on the side facing the top of the cabinet, and a first flow channel on the edge of the partition facing the first opening, the liquid collection tank is connected to the first flow channel. The edge of the containment chamber facing the first opening has a second flow channel, the extension direction of the second flow channel intersects with the extension direction of the first flow channel, and the end of the second flow channel is connected to the end of the first flow channel. Thus, the liquid generated in the containment chamber can be collected through the liquid collection tank on the partition, and the collected liquid can flow to the outside through the first and second flow channels in sequence, thereby realizing the drainage operation of the liquid in the containment chamber. The energy storage device of this application does not require the introduction of special pipelines for drainage; the drainage flow channel can be formed solely through the cooperation of the partition and the cabinet, effectively simplifying the structure of the energy storage device and solving the problem of structural complexity caused by drainage.

[0112] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.

[0113] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
