Description

Technical Field

[0001] This application relates to the field of energy storage equipment, specifically to a battery support frame and an energy storage device. Background Technology

[0002] As a type of energy storage device, energy storage containers are characterized by convenient installation and transportation, high integration, small footprint, and good scalability, making them an important component of distributed energy in the field of energy storage.

[0003] The energy storage units in an energy storage device are usually battery cells. In order to fix the battery cells, they are usually fixed on a battery support frame and secured to ensure that their position does not move, so as to avoid collisions between the battery cells and other structures and ensure their safety performance during use.

[0004] However, the existing battery support frame structure of the battery cells is not reasonable enough, making it difficult to effectively limit the position of the battery cells, and the installation and disassembly of the battery cells are also relatively inconvenient, which in turn affects the assembly and maintenance efficiency of energy storage containers. Utility Model Content

[0005] In view of this, the embodiments of this application are committed to providing a battery support frame and energy storage device to solve the technical problems that the existing battery support frame structure of the battery cell is not reasonable enough, making it difficult to effectively fix the battery cell, and the installation and disassembly of the battery cell are also relatively inconvenient, thus affecting the assembly and maintenance efficiency of the energy storage container.

[0006] The first aspect of this application provides a battery support frame, comprising: Multiple support columns are configured to extend along the height direction and are spaced apart from each other; Multiple mounting plates are fixedly mounted on multiple support columns and are stacked horizontally to form mounting positions for supporting individual battery cells. The mounting plates are provided with fastener mounting holes. Wherein, a limiting part is fixedly provided at the rear end of the mounting position in the first direction on the battery support frame, and a limiting hole is provided on the limiting part. The limiting hole is used to interlock with the limiting pin of the battery cell. The first direction is the inlet and outlet direction of the battery cell.

[0007] Another aspect of this application provides an energy storage device, comprising: At least one of the battery support frames; At least one battery cell is fixedly disposed in the mounting position of the battery support frame.

[0008] During the installation of the battery support frame in this embodiment, the battery cell needs to be placed on the mounting position on the mounting plate along the first direction, and the limiting pin of the battery cell is inserted into the upper limiting hole of the limiting part fixedly provided at the rear end of the mounting position in the first direction. The limiting pin and the limiting hole of the battery cell cooperate with each other to effectively limit the movement of the battery cell. Then, the fastener passes through the fastener mounting hole on the mounting plate and is fixedly connected to the battery cell, which can prevent the battery cell from sliding relative to the battery support frame and ensure that the battery cell is always in its corresponding mounting position. It can be seen that the battery support frame in this embodiment can effectively limit the battery cell, and the installation and disassembly of the battery cell are relatively convenient, which can effectively improve the assembly and maintenance efficiency of the battery cell.

[0022] Numerous specific details are set forth below to provide an understanding of the structure, function, and use of the embodiments described and illustrated in the specification and figures. It is to be understood that the embodiments described and illustrated herein are non-limiting examples, and thus it will be appreciated that the particular structural and functional details disclosed herein are representative and exemplary. Variations and changes may be made to these embodiments without departing from the scope of the claims.

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] like Figures 1 to 8 As shown, this application provides a battery support frame 10 for placing battery cells 20, which includes a plurality of support columns 11 and a plurality of mounting shelves 12. The plurality of support columns 11 are configured to extend along the height direction and are spaced apart from each other.

[0025] like Figure 3 As shown, the battery support frame 10 of this embodiment can be provided with four support columns 11, which are arranged in a rectangular array to ensure that the battery support frame 10 of this embodiment can be stably supported on the fixed surface. In another embodiment of this application, more support columns 11 can also be provided to improve the stability of the battery support frame 10 of this embodiment, which will not be described in detail here.

[0026] like Figures 3 to 6As shown, multiple mounting plates 12 are fixedly mounted on multiple support columns 11 and are stacked horizontally to form mounting positions for supporting battery cells 20; that is, the space above the mounting plates 12 is the mounting position for the battery cells 20; multiple mounting plates 12 stacked horizontally can form multiple mounting positions, thereby placing multiple battery cells 20.

[0027] The battery cell 20 in this embodiment can store chemical energy and controllably convert it into electrical energy. For recyclable battery cells 20, the active materials can be reactivated by charging after discharge for continued use. The battery cell 20 in this embodiment can be a lithium-ion battery, sodium-ion battery, sodium-lithium-ion battery, lithium metal battery, sodium metal battery, lithium-sulfur battery, magnesium-ion battery, nickel-metal hydride battery, nickel-cadmium battery, lead-acid battery, etc., and is not limited thereto. Figure 2 As shown, the battery cell 20 in this embodiment can be a prismatic battery cell 20 or a battery cell 20 of other shapes, and there is no limitation here.

[0028] The mounting plate 12 is provided with fastener mounting holes 124; a limiting part 13 is fixedly provided at the rear end of the mounting position in the first direction on the battery support frame 10, and the limiting part 13 is provided with a limiting hole 131, which is used to interlock with the limiting pin 21 of the battery cell 20. The first direction is the in-and-out direction of the battery cell 20. The in-and-out direction of the battery cell 20 is the direction of movement of the battery cell during the process of mounting it on the battery support frame 10.

[0029] Therefore, during the installation of the battery support frame 10 in this embodiment, the battery cell 20 needs to be placed on the mounting position on the mounting plate 12 along the first direction, and the limiting pin 21 of the battery cell 20 needs to be inserted into the limiting hole 131 on the limiting part 13 fixedly provided at the rear end of the mounting position in the first direction. The limiting pin 21 of the battery cell 20 and the limiting hole 131 cooperate with each other to effectively limit the movement of the battery cell 20. Then, the fastener passes through the fastener mounting hole 124 on the mounting plate 12 and is fixedly connected to the battery cell 20, which can prevent the battery cell 20 from sliding relative to the battery support frame 10 and ensure that the battery cell 20 is always in its corresponding mounting position. It can be seen that the battery support frame 10 in this embodiment can effectively limit the battery cell 20, and the installation and disassembly of the battery cell 20 are relatively convenient, which can effectively improve the assembly and maintenance efficiency of the battery cell 20. Understandably, in order to facilitate the installation of the battery cell 20, the limiting hole 131 can be circular in shape, and the limiting pin 21 of the battery cell 20 can be cylindrical or nearly conical in shape, so as to reduce the installation difficulty of the battery cell 20.

[0030] like Figures 3 to 5As shown, in one embodiment of this application, the limiting part 13 is provided with at least two limiting holes 131. Since the limiting part 13 is provided with at least two limiting holes 131, the at least two limiting holes 131 can be used to engage with at least two limiting pins 21 on the battery cell 20, thereby limiting the movement of the battery cell 20 and preventing relative sliding between the battery cell 20 and the battery support frame 10, ensuring that the battery cell 20 is always in its corresponding installation position.

[0031] Furthermore, such as Figures 3 to 5 As shown, in one embodiment of this application, the limiting part 13 is provided with two limiting holes 131, and the two limiting holes 131 are respectively located on both sides of the second direction at the rear end of the mounting position, the second direction being perpendicular to the first direction and the height direction.

[0032] That is, Figures 3 to 5 As shown, each battery cell 20 can be provided with two positioning pins. The two positioning pins are located on the two lateral sides of the rear end face of the battery cell 20, so that they can cooperate with the two limiting holes 131 located on both sides of the second direction at the rear end of the mounting position to limit the battery cell 20. This not only ensures that the movement of the battery cell 20 is restricted and prevents the battery cell 20 from sliding relative to the battery support frame 10, ensuring that the battery cell 20 is always in its corresponding mounting position, but also reduces the required number of positioning pins and corresponding limiting holes 131.

[0033] Specifically, such as Figures 3 to 5 As shown, in one embodiment of this application, the limiting part 13 includes a first limiting member 132 and a second limiting member 133. The first limiting member 132 and the second limiting member 133 are each provided with a limiting hole 131, which are respectively located on both sides of the second direction at the rear end of the mounting position.

[0034] In the battery support frame 10 of this application embodiment, a first limiting member 132 and a second limiting member 133 are respectively provided on both sides of the second direction at the rear end of the mounting position. Each of the first limiting member 132 and the second limiting member 133 is provided with a limiting hole 131, which cooperates with the positioning pin on the battery cell 20. In this way, the material cost of the limiting part 13 can be effectively reduced, and the limiting part 13 is not likely to affect the arrangement of other structures.

[0035] like Figures 3 to 5As shown, in one embodiment of this application, the first limiting member 132 and the second limiting member 133 are fixedly disposed on the support column 11; that is, in the processing of the battery support frame 10 in this embodiment of the application, the first limiting member 132 and the second limiting member 133 can be fixedly disposed on the support column 11 by means of welding, riveting, bolting or other methods; or the first limiting member 132, the second limiting member 133 and the support column 11 can be directly processed by means of integral molding or other methods.

[0036] Furthermore, such as Figures 3 to 5 As shown, in one embodiment of this application, a plurality of first support portions 141 are provided on the support column 11. The side surfaces of the first support portions 141 are fixedly disposed on the support column 11, and the top surfaces of the first support portions 141 are fixedly disposed on the bottom surfaces of the first limiting member 132 and / or the second limiting member 133. That is, the side surfaces of the first support portions 141 are fixedly disposed on the support column 11, and the top surfaces of the first support portions 141 can be used to support the first limiting member 132 and the second limiting member 133, avoiding deformation of the first limiting member 132 and the second limiting member 133 after long-term use.

[0037] And such Figure 8 As shown, in another embodiment of this application, the limiting part 13 is configured to extend along the second direction, with both ends fixedly disposed on the support column 11; and the limiting part 13 is provided with two limiting holes 131. That is, the limiting part 13 extending along the second direction can have two limiting holes 131, and the two ends of the limiting part 13 can be fixedly disposed on the support column 11, thereby facilitating its interlocking with the two positioning pins on each battery cell 20 to limit the movement of the battery cell 20 and prevent the battery cell 20 from sliding relative to the battery support frame 10.

[0038] In another embodiment of this application, the limiting part 13 is fixedly connected to the mounting plate 12 above the mounting position and / or the mounting plate 12 above the mounting position; that is, in the battery support frame 10 of this application embodiment, the limiting part 13 can be fixedly connected to the mounting plate 12 above the mounting position, or the limiting part 13 can be fixedly connected to the mounting plate 12 below the mounting position, or the limiting part 13 can be fixedly connected to both the mounting plate 12 above the mounting position and the mounting plate 12 above the mounting position simultaneously, thereby further improving the fixing stability of the limiting part 13 and preventing deformation.

[0039] It is understood that the above description of the limiting part 13 can be understood as a description of the limiting part 13 corresponding to one battery cell 20, and there can be a one-to-one correspondence between the limiting part 13 and the battery cell 20.

[0040] like Figure 5As shown, in one embodiment of this application, the distance between adjacent mounting plates 12 in the height direction is H(1) mm, the distance between the limiting hole 131 and the lower mounting plate 12 is H(2) mm, and H(2) / H(1) satisfies 0.15≤H(2) / H(1) ≤0.25.

[0041] In the height direction, when the relationship H(1) mm between adjacent mounting plates 12 and H(2) mm between the limiting hole 131 and the lower mounting plate 12 is less than 0.15, the limiting hole 131 is located too low, which has a poor effect on restricting the movement of the upper end of the battery cell 20 and makes it easy for the battery cell 20 to flip up and down; when H(2) / H(1) is greater than 0.15, the limiting hole 131 is located too high, which has a poor effect on restricting the movement of the upper end of the battery cell 20 and also makes it easy for the battery cell 20 to flip up and down.

[0042] Therefore, when the relationship H(2) / H(1) between the spacing H(1) mm between adjacent mounting plates 12 and the distance H(2) mm between the limiting hole 131 and the lower mounting plate 12 satisfies 0.15≤H(2) / H(1)≤0.25, it can be ensured that the limiting hole 131 is in a suitable position, minimizing the possibility of the battery cell 20 flipping up and down, and effectively limiting the movement of the battery cell 20. In a specific embodiment, the specific value of H(2) / H(1) can be selected from 0.15, 0.16, 0.17, 0.19, 0.21, 0.22, 0.23, 0.235, 0.24, 0.25, etc., and is not limited here.

[0043] Specifically, such as Figure 5 As shown, in one embodiment of this application, the spacing H(1) mm between adjacent mounting plates 12 in the height direction satisfies 240 mm ≤ H(1) mm ≤ 280 mm.

[0044] When the distance H(1) mm between adjacent mounting plates 12 is less than 240 mm, the overall height of the battery cell 20 is low, and the size occupied by the non-active parts such as the casing of the battery cell 20 is large, which will reduce the energy storage density of the support frame and the battery cell 20 as a whole in this embodiment. When the distance H(1) mm between adjacent mounting plates 12 is greater than 280 mm, the structural strength and working stability of the battery cell 20 will be weakened, and the overall weight of the battery cell 20 will also be increased, thereby increasing the assembly difficulty of the battery cell 20.

[0045] Therefore, when the spacing H(1) mm between adjacent mounting plates 12 satisfies 240 mm ≤ H(1) mm ≤ 280 mm, the energy storage density of the support frame and the battery cell 20 in this embodiment can be effectively guaranteed, as well as the structural strength and operational stability of the battery cell 20, and the assembly difficulty of the battery cell 20 can be reduced. In specific embodiments, the spacing H(1) mm between adjacent mounting plates 12 can be selected from specific values ​​such as 240 mm, 244 mm, 249 mm, 253 mm, 257 mm, 262 mm, 266 mm, 270 mm, 275 mm, 280 mm, etc., and is not limited here.

[0046] like Figure 5 As shown, in one embodiment of this application, in the height direction, the distance H(2) mm between the limiting hole 131 and the lower mounting plate 12 satisfies 40 mm ≤ H(2) mm ≤ 60 mm.

[0047] When the distance H(2) mm between the limiting hole 131 and the lower mounting plate 12 is less than 40 mm, the position of the limiting hole 131 is too low, which has a poor effect on restricting the movement of the upper end of the battery cell 20 and makes it easy for the battery cell 20 to flip up and down; when H(2) mm is greater than 60 mm, the position of the limiting hole 131 is too high, which has a poor effect on restricting the movement of the upper end of the battery cell 20 and also makes it easy for the battery cell 20 to flip up and down.

[0048] Therefore, when the distance H(2) mm between the limiting hole 131 and the lower mounting plate 12 satisfies 40 mm ≤ H(2) mm ≤ 60 mm, the position of the limiting hole 131 can be ensured to be in a suitable position, minimizing the possibility of the battery cell 20 flipping up and down, and effectively limiting the movement of the battery cell 20. In a specific embodiment, the distance H(2) mm between the limiting hole 131 and the lower mounting plate 12 can be selected from specific values ​​such as 40 mm, 43 mm, 45 mm, 47 mm, 50 mm, 52 mm, 54 mm, 56 mm, 58 mm, and 60 mm, and is not limited here.

[0049] like Figure 5 As shown, in one embodiment of this application, in the second direction, the distance between the support columns 11 on both sides of the mounting position is L(1) mm, the distance between the limiting hole 131 and the adjacent support column 11 is L(2) mm, and L(2) / L(1) satisfies 0.035≤L(2) / L(1) ≤0.085. The second direction is perpendicular to the first direction and the height direction.

[0050] When the relationship between the distance L(1) mm between the support columns 11 on both sides of the mounting position and the distance L(2) mm between the limiting hole 131 and the adjacent support column 11 is less than 0.035, the limiting part 13 is too close to the edge of the battery cell 20, which will affect the limiting and fixing effect on the battery cell 20; when L(2) / L(1) is greater than 0.085, the limiting part 13 is too close to the middle of the battery cell 20, which will also affect the limiting and fixing effect on the battery cell 20, and the required extension length of the limiting part 13 is too long, which will also affect the structural strength of the limiting part 13 itself.

[0051] Therefore, when the relationship L(1) mm between the support columns 11 on both sides of the mounting position and L(2) mm between the limiting hole 131 and the adjacent support column 11 is satisfied, the limiting part 13 can guarantee the limiting and fixing effect of the battery cell 20, and ensure that the structural strength of the limiting part 13 itself can meet the requirements and is not easily deformed. In specific embodiments, L(2) / L(1) can be selected from specific values ​​such as 0.035, 0.042, 0.048, 0.055, 0.059, 0.066, 0.071, 0.077, 0.082, 0.085, etc., which are not limited here.

[0052] like Figure 5 As shown, in one embodiment of this application, in the second direction, the distance L(1) mm between the support columns 11 on both sides of the mounting position satisfies 700 mm ≤ L(1) mm ≤ 900 mm. When the distance L(1) mm between the support columns 11 on both sides of the mounting position is less than 700 mm, the overall width of the battery cell 20 is smaller, and the size occupied by the non-active parts such as the casing of the battery cell 20 is larger, which will reduce the energy storage density of the support frame and the battery cell 20 as a whole in this embodiment of the application. When the distance L(1) mm between the support columns 11 on both sides of the mounting position is greater than 900 mm, the structural strength and working stability of the battery cell 20 will be weakened, and the overall weight of the battery cell 20 will also be increased, thereby increasing the assembly difficulty of the battery cell 20.

[0053] Therefore, when the distance L(1) mm between the support columns 11 on both sides of the mounting position satisfies 700 mm ≤ L(1) mm ≤ 900 mm, it can effectively ensure the overall energy storage density of the support frame and the battery cell 20 in this embodiment, as well as the structural strength and operational stability of the battery cell 20, and reduce the assembly difficulty of the battery cell 20. In a specific embodiment, the spacing H(1) mm between adjacent mounting plates 12 can be selected from specific values ​​such as 700 mm, 718 mm, 743 mm, 765 mm, 782 mm, 800 mm, 837 mm, 861 mm, 885 mm, and 900 mm, and is not limited here.

[0054] like Figure 5 As shown, in one embodiment of this application, in the second direction, the distance L(2) mm between the limiting hole 131 and the adjacent support column 11 satisfies 30 mm ≤ L(2) mm ≤ 60 mm. When the distance L(2) mm between the limiting hole 131 and the adjacent support column 11 is less than 30 mm, the limiting part 13 is too close to the edge of the battery cell 20, which will affect the limiting and fixing effect on the battery cell 20; when the distance L(2) mm between the limiting hole 131 and the adjacent support column 11 is greater than 60 mm, the limiting part 13 is too close to the middle of the battery cell 20, which will also affect the limiting and fixing effect on the battery cell 20, and the required extension length of the limiting part 13 is too long, which will also affect the structural strength of the limiting part 13 itself.

[0055] Therefore, when the distance L(2) mm between the limiting hole 131 and the adjacent support column 11 satisfies 30 mm ≤ L(2) mm ≤ 60 mm, the limiting part 13 can ensure the limiting and fixing effect of the battery cell 20, and ensure that the structural strength of the limiting part 13 itself can meet the requirements and is not easily deformed. In a specific embodiment, the distance L(2) mm between the limiting hole 131 and the adjacent support column 11 can be selected from specific values ​​such as 30 mm, 33 mm, 37 mm, 41 mm, 45 mm, 49 mm, 53 mm, 56 mm, 58 mm, and 60 mm, and is not limited here.

[0056] like Figures 3 to 7 As shown, in one embodiment of this application, the mounting shelf 12 includes at least two first crossbeams 121 and at least two second inner crossbeams 122. The first crossbeams 121 extend along a first direction, and the second inner crossbeams 122 extend along a second direction; the second direction is perpendicular to the first direction and the height direction. That is, in the battery support frame 10 of this application embodiment, the mounting shelf 12 can be formed using at least two first crossbeams 121 and at least two second inner crossbeams 122, which can effectively reduce the material cost and overall weight of the mounting shelf 12.

[0057] Furthermore, such as Figures 3 to 7 As shown, in one embodiment of this application, a plurality of second support portions 142 are provided on the support column 11, and the sides of the second support portions 142 are fixedly disposed on the support column 11; the battery support frame 10 also includes a bottom beam 15, which is disposed on the bottom surface of the battery support frame 10; a second internal crossbeam 122 is fixedly disposed on the top surface of the second support portion 142 or the bottom surface of the bottom beam 15; and a first crossbeam 121 is fixedly disposed on the second internal crossbeam 122.

[0058] In the battery support frame 10 of this application embodiment, multiple second support parts 142 can be provided on the support column 11. The top surface of the second support part 142 or the bottom surface of the bottom beam 15 can be used to support the second internal crossbeam 122 on the mounting plate 12. The first crossbeam 121 on the mounting plate 12 is fixedly set on the second internal crossbeam 122. This can effectively ensure the support strength of the mounting plate 12 and effectively reduce the processing and fixing difficulty of the mounting plate 12.

[0059] like Figures 3 to 7 As shown, in one embodiment of this application, the mounting plate 12 further includes a second external crossbeam 123, which is fixedly connected to the first crossbeam 121; wherein, the second external crossbeam 123 protrudes from the front end of the support column 11 in the first direction of the mounting position, and the second external crossbeam 123 is provided with fastener mounting holes 124.

[0060] By setting the second external crossbeam 123, the extension dimension of the mounting position in the first direction can be effectively expanded; and since the second external crossbeam 123 is located on the outside of the support frame and is provided with fastener mounting holes 124, fasteners can pass through the fastener mounting holes 124 on the second external crossbeam 123 and be fixedly connected to the battery cell 20, which facilitates the fixed installation of the battery cell 20 and reduces the installation difficulty of the battery cell 20.

[0061] like Figures 3 to 7 As shown, in one embodiment of this application, the mounting plate 12 further includes two side limiting plates 125. The two side limiting plates 125 are respectively located on the side of the two first crossbeams 121 at both ends away from the mounting position, and are configured to extend along the height direction. By providing two side limiting plates 125 on the side of the two first crossbeams 121 at both ends away from the mounting position, the left and right movement of the battery cell 20 can be restricted during the installation of the battery cell 20, ensuring that the battery cell 20 can reach its corresponding installation position and be fixedly mounted on the battery support frame 10 of this embodiment.

[0062] like Figures 3 to 6As shown, in one embodiment of this application, the battery support frame 10 further includes at least one reinforcing beam 16; both ends of the reinforcing beam 16 are fixedly connected to two support columns 11, and the extension direction of the reinforcing beam 16 forms an acute angle with the height direction. By providing a reinforcing beam 16 extending in an inclined direction in the battery support frame 10 of this application embodiment, the structural strength of the battery support frame 10 of this application embodiment can be further improved, and deformation of the battery support frame 10 of this application embodiment can be avoided after long-term use.

[0063] This application also provides an energy storage device, which includes at least one of the aforementioned battery support frames 10 and at least one battery cell 20, wherein the battery cell 20 is fixedly disposed in the mounting position of the battery support frame 10. It is understood that this energy storage device can be various energy storage devices such as energy storage containers and energy storage cabinets, and is not limited thereto.

[0064] It should be noted that the elements described in the above specific embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, this application will not describe the various possible combinations separately.

[0065] It should be understood that multiple components and / or parts can be provided by a single integrated component or part. Alternatively, a single integrated component or part can be divided into multiple separate components and / or parts.
