Description

Technical Field

[0001] This utility model relates to the field of energy storage technology, and specifically to an energy storage container system. Background Technology

[0002] In most energy storage applications, battery energy storage systems are installed in fixed locations and then connected to the power grid. The main structure of the energy storage system is a metal enclosure, inside which battery modules and a bottom shell are housed. The battery modules are mounted on the bottom shell, which has a hollow interior forming a liquid-cooling cavity to dissipate heat and cool the battery modules, ensuring the safety of the energy storage system. However, directly forming the liquid-cooling channels at the bottom of the battery enclosure not only poses a short-circuit problem due to leakage from ruptures, but also results in relatively thick and heavy enclosure walls to withstand hydraulic pressure, leading to high costs. Utility Model Content

[0003] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, embodiments of this invention propose an energy storage container system. This energy storage container system has the advantages of reduced material costs, high ease of assembly and disassembly, and high safety performance.

[0004] The energy storage container system of this utility model embodiment includes a battery box bracket, multiple energy storage boxes, and a liquid cooling system.

[0005] The battery box bracket is equipped with an independently configured cooling chamber and multiple battery chambers, with each of the energy storage boxes correspondingly positioned within one of the battery chambers. Each energy storage box includes a battery module, a main body cover, and a battery box base plate. The battery box base plate has a connecting surface and a mating surface that are oppositely arranged. The main body cover is positioned on the connecting surface to form a receiving cavity for accommodating the battery module, and the mating surface has a receiving slot. A portion of the liquid cooling system is disposed within the cooling chamber, and another portion of the liquid cooling system is engaged within the receiving slot. The receiving slot has an opening on one side of the battery box bracket in the width direction, and the portion of the liquid cooling system can extend out of the battery box base plate through the corresponding opening. It is understood that the liquid cooling system is located on the outside of the energy storage box and is not connected to the interior of the energy storage box.

[0006] The energy storage container system of this embodiment features a receiving slot on the mating surface of the battery box bottom plate, into which a portion of the liquid cooling system is secured. This means that a part of the liquid cooling system is located on the outside of the energy storage box and is not connected to the inside of the box, thus preventing short circuits and fires caused by leaks from ruptured liquid cooling channels. Therefore, this energy storage container system improves operational safety. Simultaneously, the external liquid cooling system reduces the thickness requirements of the battery box bottom plate, significantly reducing the overall weight of the bottom shell structure. Furthermore, separately installed liquid cooling pipes are relatively inexpensive, further reducing the overall production cost of the equipment.

[0007] Furthermore, by placing a portion of the liquid cooling system on the outside of the energy storage tank, the system can be pre-installed during assembly, eliminating the need for a sealed connection between the cooling pipes and the energy storage tank, thus simplifying the assembly process. Moreover, in the event of damage during use, individual sections of the cooling pipes can be replaced, further enhancing maintenance convenience.

[0008] Therefore, the energy storage container system of this utility model has the advantages of reduced material costs, high ease of assembly and disassembly, and high safety performance.

[0009] In some embodiments, the liquid cooling system includes a liquid cooler, an inlet pipe, an outlet pipe, and multiple liquid cooling coil sections.

The multiple liquid cooling coil sections are correspondingly engaged in the receiving slots of the multiple battery box bottom plates. The liquid cooler is disposed in the cooling chamber.

[0010] In some embodiments, the battery compartments are arranged in multiple rows and columns, and at least a portion of the liquid inlet pipe and the liquid outlet pipe extends along the height direction of the battery box support. The liquid cooling coil segments corresponding to multiple battery compartments in the same row are sequentially connected in series to form a liquid cooling main row, and the multiple liquid cooling main rows are arranged in parallel between the liquid inlet pipe and the liquid outlet pipe.

[0011] In some embodiments, the mating surface has a plurality of limiting grooves extending along the width direction of the battery box bracket, the plurality of limiting grooves being spaced apart along the length direction of the battery box bracket to form a limiting protrusion between adjacent limiting grooves, one end of each limiting groove being open along the length direction, the liquid cooling coil segment being arranged in a meandering manner, the liquid cooling coil segment having a first end and a second end along the width direction of the battery box bracket, the portion of the first end having a meandering bend angle being disposed in the receiving slot, and the portion of the second end having a meandering bend angle being engaged on the limiting protrusion.

[0012] In some embodiments, both the inlet pipe and the outlet pipe are provided with multiple external connectors, which are connected to the outermost liquid cooling coil section of the multiple liquid cooling main body rows.

[0013] In some embodiments, two adjacent liquid cooling coil sections in the same row are provided with a connecting buckle at the connection point. The connecting buckle is disposed on the battery box bracket and is detachably snapped onto the liquid cooling coil section.

[0014] In some embodiments, the battery box support includes a container frame and a plurality of partition plates and a plurality of bottom support members disposed within the container frame. The plurality of partition plates are spaced apart and connected to the top and bottom plates of the container frame along the length direction of the container frame. Each bottom support member is connected to two adjacent partition plates, and each bottom support member forms a placement position for placing the battery box.

[0015] In some embodiments, the bottom support member includes a bottom support plate and a shock-absorbing layer. The bottom support plate is connected to two adjacent partition plates. The bottom support plate has a support surface and a recessed receiving groove. The battery box bottom plate is disposed on the support surface, and the shock-absorbing layer is disposed in the receiving groove.

[0016] In some embodiments, the bottom support plate includes an integrally bent main body section, an extension section, and a flange section. The extension section is formed on both sides of the main body section along the length direction of the container frame, and the extension section extends upward along the opposite edges of the main body section to form the receiving groove. The flange section extends along the upper end of the extension section toward the direction close to the partition plate, and the flange section is connected to the partition plate. The shock-absorbing layer is disposed on the main body section.

[0017] In some embodiments, a stop portion is provided on one of the partition plate or the bottom support member, and the bottom plate of the battery box abuts against the stop portion.

[0018] In some embodiments, the outermost partition plate is spaced from the side plate of the container frame to form a cooling chamber on one side and a heat insulation zone on the other side.

[0019] In some embodiments, the stop portion is a U-shaped groove formed by bending, the edge of the battery box bottom plate extends outside the main body cover of the box, the edge of the battery box bottom plate is embedded in the U-shaped groove, and the U-shaped groove can engage a part of the battery box.

[0040] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0041] The following is for reference. Figures 1-12 This invention describes an energy storage container system according to an embodiment of the present invention.

[0042] The energy storage container system of this utility model embodiment includes a battery box bracket 1, multiple energy storage boxes 2, and a liquid cooling system 3.

[0043] The battery box bracket 1 has multiple battery compartments 101, and multiple energy storage boxes 2 are correspondingly arranged in the battery compartments 101. Each energy storage box includes a battery module, a main body cover 21, and a battery box base plate 22. The battery box base plate 22 has a connecting surface and a mating surface that are arranged opposite each other. The main body cover 21 is disposed on the connecting surface to form a receiving cavity for accommodating the battery module, and the mating surface has a receiving slot. A portion of the liquid cooling system 3 is engaged in the receiving slot. The receiving slot has an opening on one side of the battery box bracket 1 in the width direction, and a portion of the liquid cooling system 3 can extend out of the battery box base plate 22 through the corresponding opening. It is understood that the liquid cooling system 3 is located on the outside of the energy storage box and is not connected to the inside of the energy storage box.

[0044] The energy storage container system of this embodiment features a receiving slot on the mating surface of the battery box bottom plate 22, within which a portion of the liquid cooling system 3 is secured. This means that a portion of the liquid cooling system 3 is positioned on the outside of the energy storage container and is not connected to the interior, thus preventing short circuits and fires caused by leakage from ruptured liquid cooling channels. This enhances the safety of the energy storage container system. Furthermore, the external placement of the liquid cooling system 3 on the energy storage container 2 reduces the thickness requirements of the battery box bottom plate 22, significantly reducing the overall weight of the bottom shell structure. Additionally, the relatively low cost of separately installed liquid cooling pipes further reduces the overall production cost of the equipment.

[0045] Furthermore, a portion of the liquid cooling system 3 is located on the outside of the energy storage tank. During installation, the liquid cooling system 3 can be pre-installed, eliminating the need for a sealed connection between the cooling pipes and the energy storage tank, thus simplifying the assembly process. Moreover, in case of damage during use, a specific section of the cooling pipe can be replaced individually, further improving maintenance convenience.

[0046] Therefore, the energy storage container system of this utility model has the advantages of reduced material costs, high ease of assembly and disassembly, and high safety performance.

[0047] Understandably, multiple battery modules can be installed inside the energy storage box.

[0048] like Figures 2 to 5 As shown, the liquid cooling system 3 includes a liquid cooler 31, an inlet pipe 32, an outlet pipe 33, and multiple liquid cooling coil sections 34. The liquid cooler 31, the inlet pipe 32, the multiple liquid cooling coil sections 34, and the outlet pipe 33 are connected in a sequential cycle. The multiple liquid cooling coil sections 34 are correspondingly engaged with the receiving slots of the multiple battery box bottom plates 22.

[0049] The energy storage container system of this utility model divides the liquid cooling system 3 into a liquid cooler 31, an inlet pipe 32, an outlet pipe 33, and multiple liquid cooling coil sections 34. The multiple liquid cooling coil sections 34 are correspondingly engaged in the receiving slots of multiple battery box bottom plates 22. That is, the liquid cooling coil sections 34 can be positioned and installed by the receiving slots, thereby improving the stability of the structure and the convenience of installation.

[0050] Furthermore, each liquid cooling coil segment 34 can be integrally bent and formed, and multiple liquid cooling coil segments 34 can be sealed and connected together. This not only provides the advantage of good overall structural integrity but also facilitates segmented replacement during later maintenance.

[0051] like Figures 1 to 4 As shown, the battery box bracket 1 also has a cooling chamber 102, which is set independently from the battery chamber 101. The liquid cooler 31 is set in the cooling chamber 102. The battery chambers 101 are arranged in multiple rows and columns. At least a portion of the liquid inlet pipe 32 and the liquid outlet pipe 33 extend along the height direction of the battery box bracket 1. The liquid cooling coil sections 34 corresponding to the multiple battery chambers 101 in the same row are connected in series to form a liquid cooling main row. The multiple liquid cooling main rows are connected in parallel between the liquid inlet pipe 32 and the liquid outlet pipe 33.

[0052] The energy storage container system of this embodiment of the utility model, by setting the battery compartment 101 and the cooling compartment 102 relatively independently, can to a certain extent isolate the heat dissipated from the cooling compartment 102 to the battery compartment 101, and avoid the problem of poor heat dissipation caused by the heat generated by the liquid cooler 31 entering the battery compartment 101. Thus, the heat dissipation effect on the battery module is improved.

[0053] In addition, the liquid cooling coil sections 34 corresponding to the multiple battery compartments 101 in the same row are connected in series to form a liquid cooling main row. The multiple liquid cooling main rows are connected in parallel between the liquid inlet pipe 32 and the liquid outlet pipe 33, which facilitates the simplification of the piping in the liquid cooling system 3.

[0054] like Figure 7 and Figure 9 As shown, the mating surface has multiple limiting grooves 221 extending along the width direction of the battery box bracket 1. The multiple limiting grooves 221 are spaced apart along the length direction of the battery box bracket 1 to form limiting protrusions 222 between adjacent limiting grooves 221. One end of each limiting groove 221 is open along its length direction. The liquid cooling coil section 34 is arranged in a meandering manner. The liquid cooling coil section 34 has a first end and a second end along the width direction of the battery box bracket 1. The portion of the first end with a meandering bend angle is disposed in the receiving slot, and the portion of the second end with a meandering bend angle is engaged on the limiting protrusion 222.

[0055] The energy storage container system of this embodiment features a liquid-cooled coil section 34 arranged in a circuitous and bent manner. Simultaneously, the portion with the first bend angle is positioned within a receiving slot, while the portion with the second bend angle is engaged with a limiting protrusion 222. Therefore, during assembly and disassembly, the liquid-cooled coil section 34 can be inserted into the receiving slot from the open end of the battery box bottom plate 22, eliminating the need to disassemble the entire energy storage box 2 before replacing it. Thus, the energy storage container system of this embodiment further enhances the ease of assembly and disassembly of the liquid-cooled system 3.

[0056] Furthermore, adjacent liquid cooling coil sections 34 are sealed together by connectors, allowing for quick pipe replacement by simply plugging and unplugging the water cooling pipe connectors, greatly reducing the replacement process.

[0057] Optionally, the battery box bottom plate 22 is integrally formed from an aluminum plate or a steel plate through slotting. Therefore, the energy storage container system of this embodiment has the advantages of good structural integrity and high strength.

[0058] like Figure 4 and Figure 5 As shown, both the inlet pipe 32 and the outlet pipe 33 are provided with multiple external connectors 35, which are connected to the outermost liquid cooling coil section 34 of the multiple liquid cooling main body.

[0059] The energy storage container system of this utility model has multiple external connectors 35 on both the inlet pipe 32 and the outlet pipe 33. These external connectors 35 are then connected to the outermost liquid cooling coil section 34 of the multiple liquid cooling main body. This connection structure further improves the ease of installation of the inlet pipe 32 and the outlet pipe 33 with the liquid cooling main body.

[0060] like Figure 4 and Figure 5 As shown, two adjacent liquid cooling coil sections 34 in the same row are provided with connecting buckles 36 at the connection point. The connecting buckles 36 are set on the battery box bracket 1 and can be detachably snapped onto the liquid cooling coil section 34.

[0061] The energy storage container system of this utility model is connected to the battery box bracket 1 by connecting buckles 36 at the connection points of two adjacent liquid-cooled coil sections 34 in the same row, which improves the stability of the connection of the liquid-cooled coil sections 34. In addition, the connecting buckles 36 are detachably fastened to the liquid-cooled coil sections 34, which further improves the convenience of assembling and disassembling the liquid-cooled coil sections 34.

[0062] like Figure 1 and Figure 2 As shown, the battery box bracket 1 includes a container frame 11 and a plurality of partition plates 12 and a plurality of bottom support members 13 disposed within the container frame 11. The plurality of partition plates 12 are spaced apart and connected to the top plate and the bottom plate of the container frame 11 along the length direction of the container frame 11. Each bottom support member 13 is connected to two adjacent partition plates 12, and each bottom support member 13 forms a placement position for placing the battery box.

[0063] The energy storage container system of this utility model divides the battery box support 1 into a container frame 11 and multiple partition plates 12 and multiple bottom support members 13 disposed within the container frame 11. The multiple bottom support members 13 form multiple battery box placement positions. That is, multiple battery box placement positions are formed by a frame and partitions, which not only has a simple structure, but also has relatively good frame structure stability.

[0064] Specifically, the connecting clip 36 can be fixed to the partition plate 12 by screws. Furthermore, the connecting clip 36 can be a hinge structure, with two opposing spring clip structures having engagement grooves on them.

[0065] like Figure 1 and Figure 2 As shown, there is a gap between the outermost partition plate 12 and the side plate of the container frame 11 to form a cooling chamber 102 on one side and a heat insulation zone on the other side. This helps to prevent excessive influence from the external environment.

[0066] like Figure 6 , Figure 9 and Figure 10 As shown, the bottom support member 13 includes a bottom support plate 131 and a shock-absorbing layer 132. The bottom support plate 131 is connected to two adjacent partition plates 12. The bottom support plate 131 has a support surface and a recessed receiving groove 1314. The battery box bottom plate 22 is disposed on the support surface, and the shock-absorbing layer 132 is disposed in the receiving groove 1314.

[0067] The energy storage container system of this embodiment features a recessed bottom support plate 131 forming a receiving groove 1314, within which a shock-absorbing layer 132 is installed. This is because the battery may encounter vibrations or impacts during transportation or use. The shock-absorbing layer 132 provides elastic support for the battery box and effectively absorbs these external forces, reducing direct physical damage to the battery box and its internal batteries. Simultaneously, the shock-absorbing layer 132 also reduces the problem of loose electrical connections between the battery and other components, ensuring the reliability of electrical connections. Therefore, this energy storage container system reduces transportation losses.

[0068] like Figure 1 and Figure 12 As shown, the bottom support plate 131 includes an integrally bent main body section 1311, an extension section 1312, and a flange section 1313. The extension section 1312 is disposed on both sides of the main body section 1311 along the length of the container frame 11, and the extension section 1312 extends upward along the opposite edges of the main body section 1311 to form receiving grooves 1314. The flange section 1313 extends along the upper end of the extension section 1312 toward the direction close to the partition plate 12, and the flange section 1313 is connected to the partition plate 12. The shock-absorbing layer 132 is disposed on the main body section 1311. It can be understood that the bottom support plate 131 includes the main body section 1311, the extension section 1312 extending upward along the opposite edges of the main body section 1311, and the flange section 1313 extending along the upper end of the extension section 1312 toward the direction close to the partition plate 12.

[0069] The energy storage container system of this utility model, by integrally bending the main body section 1311, extension section 1312 and flange section 1313 of the bottom support plate 131 to form a receiving groove 1314, not only has the advantages of good structural integrity and high stability, but also the outer flange section 1313 facilitates positioning and installation with the partition plate 12.

[0070] Optionally, the shock-absorbing layer 132 can be a foam layer. This is because foam layers not only offer advantages such as lightweight and good shock absorption, but also often possess good thermal insulation properties, helping to maintain a relatively stable operating environment for the battery.

[0071] Furthermore, the foam layer is adhered to the main body section 1311. Adhering the foam layer to the main body section 1311 improves the ease of installation of the shock-absorbing layer 132.

[0072] like Figure 10 and Figure 11 As shown, a stop 133 is provided on one of the partition plate or the bottom support member 13, and the bottom plate 22 of the battery box abuts against the stop 133.

[0073] The energy storage container system of this embodiment of the invention has a stop 133 on either the partition plate or the bottom support member 13, which can limit the position of the battery box. Therefore, this energy storage container system improves the stability of the battery box during transportation.

[0074] like Figure 10 and Figure 11 As shown, the stop part 133 is a U-shaped groove formed by bending. The edge of the battery box bottom plate 22 extends out of the main body cover 21. The edge of the battery box bottom plate 22 is embedded in the U-shaped groove, which can engage a part of the battery box.

[0075] The energy storage container system of this utility model fixes the energy storage box 2 by bending the stop part 133 into a U-shaped slot, which engages with the bottom plate 22 of the battery box. This avoids the problem of collision caused by the displacement of the energy storage box 2 during transportation, and further reduces the problem of transportation damage.

[0076] Optionally, the stop portion 133 can be formed by bending. Furthermore, this structural method has the advantages of high processing convenience and good overall structural integrity.
