Technical Field

[0004] , ,

[0001] The present invention relates to a wall-mounted structure of an energy storage device, and more particularly, to a wall-mounted structure capable of mounting an energy storage device on a wall for storage.

Background Art

[0002] A secondary battery refers to a rechargeable battery, unlike a non-rechargeable primary battery, and is applied not only to portable devices but also to electric vehicles (EVs), hybrid electric vehicles (HEVs), etc. driven by an electric drive source.

[0003] Currently widely used types of secondary batteries include lithium-ion batteries, lithium polymer batteries, nickel cadmium batteries, nickel metal hydride batteries, nickel zinc batteries, etc. The operating voltage of such a unit secondary battery cell, i.e., a unit battery cell, is about 2.5V to 4.6V. Therefore, when a higher output voltage is required, a large number of battery cells are connected in series to form a battery pack. Also, depending on the charge / discharge capacity required for the battery pack, a large number of battery cells may be connected in parallel to form a battery pack. Therefore, the number of battery cells included in the battery pack can be variously set according to the required output voltage or charge / discharge capacity.

[0004] When a large number of battery cells are connected in series / parallel to form a battery pack, generally, at least one battery cell, preferably a battery module composed of a large number of battery cells, is first configured, and at least one such battery module is used, and other components are added to form a battery pack. Here, a battery module means a component in which a large number of battery cells are connected in series or parallel, and a battery pack may mean a component in which a large number of battery modules are connected in series or parallel in order to increase the capacity and output, etc.

[0005] Recently, energy storage devices have been used to store the electricity produced, and these energy storage devices may consist of multiple battery modules.

[0006] Energy storage devices are small and can be used in homes; however, such small energy storage devices may require a separate installation method. [Overview of the project] [Problems that the invention aims to solve]

[0034] An energy storage device 1000 according to one embodiment of the present invention may include a case 100, a plurality of battery modules 200, and a support frame 300 for supporting the battery modules 200.

[0035] The case 100 forms the outer casing of the energy storage device 1000 and can accommodate a plurality of battery modules 200 and support frames 300. It may also include a main body 110 and a door 120.

[0036] In case 100, the main body 110 may include a bottom portion 111, a front portion 112, a rear portion 114, a side portion 113, and a top portion 115.

[0037] The bottom 111 of the main body 110 can be formed as a horizontally extending plate shape. Four support feet 111a for supporting the case 100 may be positioned at each corner of the outer lower surface of the bottom 111.

[0038] In the main body 110, the front portion 112 and the rear portion 114 can form the front and rear surfaces of the case 100, respectively, and can be positioned at the front and rear edges of the bottom portion 111 and top portion 115, respectively.

[0039] The main body 110 has a side portion 113 which forms one side of the case 100 and can be positioned at the left edge or right edge of the bottom 111 and top portion 115, respectively.

[0040] The front section 112, the rear section 114, and the side section 113 can form the sides of the case 100 together with the door 120.

[0041] The main body 110 has an upper surface 115 which is positioned on top of the case 100 and can cover the inside of the case 100. The upper surface 115 can have a structure for installing electrical equipment such as a power conversion system (PCS) on its outer upper surface.

[0042] The door 120 is attached to one side of the main body 110 and can open and close the inside of the case 100. The door 120 can be positioned on the opposite side of the side portion 113 of the case 100, facing the side portion 113, and can form one side of the case 100.

[0043] The door 120 is rotatably connected to the body 110 by hinges, and can also be connected to the body 110 so that it can be completely separated from the body 110.

[0044] One embodiment of the present invention may include a locking device for the door 120.

[0045] In case 100, the areas of the side portion 113 and the door 120 are the same or approximately the same, and the areas of the side portion 113 and the door 120 may be larger than the area of ​​the bottom portion 111. For example, the areas of the side portion 113 and the door 120 may be more than twice the area of ​​the bottom portion 111. Therefore, as shown in the figure, in case 100 of the energy storage device 1000, one side with a large area does not form the bottom, but is arranged to form the side of case 100 and stand upright, thereby reducing the installation area.

[0046] In one embodiment of the present invention, the energy storage device 1000 can be coupled to a wall-mounted bracket 500 and mounted on a wall W. Figures 3 to 11 are diagrams illustrating a wall-mounted structure according to one embodiment of the present invention.

[0047] The wall mounting bracket 500 can be fixed to the wall W and support the energy storage device 1000.

[0048] As shown in Figure 3, the wall-mounted bracket 500 includes a plurality of connecting holes 510. A fixing member 511 is connected to each connecting hole 510, and the wall-mounted bracket 500 can be fixed to the wall W by the fixing member 511. The fixing member 511 connected to the connecting hole 510 may be a screw, nail, anchor, anchor bolt, etc.

[0049] In this embodiment, the coupling hole 510 can extend horizontally (in the Y-axis direction). By extending the coupling hole 510 in the width direction (in the Y-axis direction) of the wall-mount bracket 500, the fixing position of the fixing member 511 within the coupling hole 510 can be adjusted. Multiple coupling holes 510 can be arranged on the left and right sides of the wall-mount bracket 500, as shown in the figure, and may also be arranged on the upper and lower sides.

[0050] The wall-mount bracket 500 may include a rack bracket 550.

[0051] The rack bracket 550 is for supporting the coupling bracket 150 which is located on the rear surface of the energy storage device 1000, and may extend in the width direction (Y-axis direction) of the wall-mount bracket 500.

[0052] The rack bracket 550 may include a coupling portion 551 that connects to the wall-mount bracket 500, a support portion 552, and an upward extension portion 553 (see Figures 3 and 10).

[0053] The connecting portion 551 is formed by bending upward from the rear end of the support portion 552, and the connecting portion 551 can be joined to the wall-mounted bracket 500 by welding or other means.

[0054] In this embodiment, the connecting portion 551 may be positioned on both the left and right sides of the wall-mounted bracket 500.

[0055] The support portion 552 extends in the width direction (Y-axis direction) of the wall-mounted bracket 500 and can have a plate shape that extends long in one direction.

[0056] As shown in Figures 9 and 10, the support portion 552 can support the support projection 155 of the connecting bracket 150 from below.

[0057] The upper extensions 553 are positioned on both sides of the support portion 552 and may be formed by bending upward from the front end of the support portion 552.

[0058] The upper extension 553 can support one side of the support projection 155, and together with the support portion 552, as shown in Figure 10, it can support the support projection 155. By extending the upper extension 553 upward from one end of the support portion 552 and supporting one side of the support projection 155, it is possible to prevent the support projection 155 from detaching from the wall-mounted bracket 500 in the forward direction (X-axis direction).

[0059] The upper end of the upper extension 553 may be formed to curve forward, as shown in Figure 10. This forward-curving shape of the upper end of the upper extension 553 allows the support projection 155 of the coupling bracket 150 to easily move inward into the upper extension 553 when it is moved downward to connect to the rack bracket 550, as shown in Figure 8.

[0060] The connecting portion 551, the support portion 552, and the upward extension portion 553 that constitute the rack bracket 550 can be formed integrally.

[0061] The rack brackets 550 are positioned above and below the wall-mount bracket 500, respectively, and each rack bracket 550 can support the support projection 155.

[0062] Therefore, the coupling bracket 150, which is positioned on the rear surface of the energy storage device 1000, can be placed on the rack bracket 550, allowing the energy storage device 1000 to be mounted on the wall-mount bracket 500.

[0063] A wing plate 530 may be placed at each end of the wall-mounted bracket 500.

[0064] The vane plates 530 can be formed by bending them forward from both ends of the wall-mounted bracket 500. As shown in Figure 3, each vane plate 530 may include a protruding plate 531 and a coupling hole 532, the coupling hole 532 of which may be formed in the protruding plate 531. A coupling member 151b for coupling the coupling bracket 150 and the wall-mounted bracket 500 can be inserted into the coupling hole 532.

[0065] The protruding plate 531 is formed such that a certain area of ​​the vane 530 bulges outward, and the vane 530 protrudes outward in the area of ​​the protruding plate 531, thereby increasing the overall thickness.

[0066] The protruding plate 531 of the vane plate 530, which is formed to bulge outward, can contact the outer plate 151 of the coupling bracket 150. The coupling member 151b passes sequentially through the coupling hole 151a formed in the outer plate 151 of the coupling bracket 150 and the coupling hole 532 of the vane plate 530, and can be screw-connected to a nut (not shown) on the inside of the protruding plate 531. The nut (not shown) to which the coupling member 151b is connected is positioned on the inner surface of the protruding plate 531 (the side opposite to the surface of the protruding plate 531 that faces the outer plate 151), and can also be fixed to the inner surface of the protruding plate 531 by welding or the like. In this way, since the protruding plate 531 can be tightened using the coupling member 151b while it is protruding from the vane plate 530 and in contact with the outer plate 151, the vane plate 530 and the outer plate 151 can be firmly connected. The coupling member 151b may be a bolt or the like.

[0067] Multiple protruding plates 531 and connecting holes 532 can be arranged in the vertical direction (Z direction) of the vane plate 530.

[0068] As shown in the figure, the wall-mounted bracket 500 may have multiple through holes 501. By forming multiple through holes 501 in the wall-mounted bracket 500, the self-load of the wall-mounted bracket 500 is reduced, and air circulation becomes smoother, which helps in cooling the energy storage device 1000.

[0069] The coupling bracket 150, which is positioned on the rear surface (rear surface of the side portion 113) of the main body 110 of the case 100, can be positioned on the left and right sides of the rear surface of the main body 110, as shown in Figure 5.

[0070] Each connecting bracket 150 can extend vertically (in the Z-axis direction) from the rear edge of the main body 110 and may include a connecting plate 152, an outer plate 151, and an inner plate 153.

[0071] The connecting plate 152 can extend vertically along the rear edge of the main body 110 and can be joined to the rear surface of the main body 110 by welding or other means.

[0072] The outer plate 151 is formed by bending the outer end of the connecting plate 152 backward (towards the wall-mounted bracket 500), and multiple connecting holes 151a can be formed along the vertical direction. The connecting members 151b inserted into the connecting holes 151a are connected to the connecting holes 532 of the wing plate 530, thereby connecting the outer plate 151 and the wing plate 530.

[0073] The inner plate 153 is formed by bending the inner end of the connecting plate 152 backward (towards the wall-mounted bracket 500), and may be positioned facing the outer plate 151 and parallel to the outer plate 151.

[0074] Support projections 155 may be provided on the inner plate 153. The support projections 155 extend downward, and as described above, the support projections 155 are supported by the rack bracket 550, thereby enabling the energy storage device 1000 to be mounted on the wall bracket 500.

[0075] The support projections 155 are positioned on the upper and lower sides, respectively, and the upper and lower support projections 155 can be connected to the upper and lower rack brackets 550 of the wall-mount bracket 500, respectively.

[0076] Figures 6 to 11 show the process of mounting the energy storage device 1000 onto the wall-mounted bracket 500.

[0077] As shown in Figure 6, with the energy storage device 1000 separated from the wall-mount bracket 500, the energy storage device 1000 can be moved toward the wall-mount bracket 500, allowing it to be brought into close contact with the wall-mount bracket 500. Here, the support projection 155 of the coupling bracket 150 is positioned on the upper side of the rack bracket 550.

[0078] Subsequently, as shown in Figures 7 and 8, the energy storage device 1000 is moved downward along the wall, causing the support projections 155 of the coupling bracket 150, which is positioned on the rear surface (side portion 113) of the main body 100 of the case 100 of the energy storage device 1000, to be supported by the rack bracket 550 of the wall-mounted bracket 500. Here, the vane 530 of the wall-mounted bracket 500 is positioned between the outer plate 151 and the inner plate 153 of the coupling bracket 150, and each support projection 155 of the coupling bracket 150 on both sides is supported by the support portion 552 inside the upper extension portion 553 of the rack bracket 550.

[0079] Figure 10 is a detailed view showing the state in which the support projection 155 of the connecting bracket 150 is supported by the rack bracket 550 of the wall-mounted bracket 500.

[0080] In this manner, with the support projections 155 positioned on the upper and lower sides of the connecting bracket 150 supported by the rack brackets 550 positioned on the upper and lower sides of the wall-mounted bracket 500, the connecting bracket 150 is fixed to the wall-mounted bracket 500 with the connecting member 151b.

[0081] The coupling bracket 150 can be fixed to the wall-mounted bracket 500 using the coupling member 151b by inserting the coupling member 151b into the coupling hole 151a formed in the outer plate 151 of the coupling bracket 150 and the coupling hole 532 in the wing plate 530, and then screwing it with a nut (not shown) inside the coupling hole 532.

[0082] In this way, the mounting of the energy storage device 1000 to the wall-mounted bracket 500 is completed by tightening the connecting member 151b and firmly fixing the connecting bracket 150 to the wall-mounted bracket 500.

[0083] As described above, the wall-mounted structure of the energy storage device 1000 according to this embodiment ensures structural rigidity to support the energy storage device 1000, and since the energy storage device 1000 is mounted by hanging it on a wall-mounted bracket 500 fixed to the wall W, installation is easy and a structure to support the bottom of the energy storage device 1000 is unnecessary. Furthermore, in this embodiment, the wall-mounted bracket 500 is hardly exposed to the outside, and the coupling bracket 150 of the energy storage device 1000 is fixed to the wall-mounted bracket 500 with a coupling member 151b, thereby preventing movement of the rear surface of the energy storage device 1000 and improving seismic resistance.

[0084] Figure 12 shows a wall-mounted structure of the energy storage device 1000 according to another embodiment, and is a partial plan view of the energy storage device 1000 coupled to the wall-mounted bracket 500.

[0085] In another embodiment shown in Figure 12, the coupling bracket 150 may further include an extension support plate 154 extending from the inner plate 153 and a side support plate 154a extending from the extension support plate 154.

[0086] The extension support plate 154 can be bent from the inner plate 153 of the coupling bracket 150 toward the outer plate 151 and extend along the wall mounting bracket 500. The extension support plate 154 can contact the wall mounting bracket 500 and can be supported by the wall mounting bracket 500.

[0087] The side support plate 154a can be bent from the end of the extension support plate 154 toward the connecting plate 152 and extend along the vane 530 of the wall-mounted bracket 500. The side support plate 154a can contact the vane 530 and can be supported by the vane 530.

[0088] Another embodiment shown in Figure 12 further includes an extension support plate 154 that extends from the inner plate 153 of the coupling bracket 150 toward the outer plate 151, and a side support plate 154a that is bent from the extension support plate 154 and can contact the vane plate 530. This further suppresses lateral movement and vibration of the energy storage device 1000, and allows for more stable support of the energy storage device 1000.

[0089] Figure 13 shows a wall-mounted structure of the energy storage device 1000 according to another embodiment, and is a partial plan view of the energy storage device 1000 coupled to the wall-mounted bracket 500.

[0090] In another embodiment shown in Figure 13, the coupling bracket 150 may further include an extension support plate 154 extending from the inner plate 153, a side support plate 154a extending from the extension support plate 154, and an elastic member 154b positioned outside the side support plate 154a.

[0091] The extension support plate 154 can be bent from the inner plate 153 of the connecting bracket 150 toward the outer plate 151 and extend along the wall mounting bracket 500. The extension support plate 154 can contact the wall mounting bracket 500 and can be supported by the wall mounting bracket 500.

[0092] The side support plate 154a can be bent from the end of the extension support plate 154 toward the connecting plate 152 and extend along the vane 530 of the wall-mounted bracket 500.

[0093] The elastic member 154b is positioned between the side support plate 154a and the vane 530, and can elastically support the vane 530 by contacting it. The elastic member 154b may be made of rubber, silicone, synthetic resin foam, or the like.

[0094] Another embodiment shown in Figure 13 further includes an extension support plate 154 that extends from the inner plate 153 of the coupling bracket 150 toward the outer plate 151, a side support plate 154a that is bent from the extension support plate 154 and can contact the vane plate 530, and an elastic member 154b that elastically supports the vane plate 530 with the side support plate 154a. This further suppresses lateral movement and vibration of the energy storage device 1000 and allows for more stable support of the energy storage device 1000.

[0095] The battery module 200 may include a module case 210 and a plurality of cell module assemblies (CMAs) (not shown) housed within the module case 210, as shown in Figures 14 and 15.

[0096] The cell module assembly (CMA) housed in the module case 210 comprises multiple battery cells, and the multiple battery cells in each cell module assembly may be arranged in close contact with each other.

[0097] Each battery cell may be, for example, a pouch-type battery cell 250. The pouch-type battery cell 250 may have a structure in which an electrode assembly is housed within a pouch-type case.

[0098] For example, a cell module assembly may comprise multiple battery cells stacked or closely spaced together, and each battery cell may have electrode leads 251, 252 at its front and / or rear ends, with a positive electrode lead at the front end and a negative electrode lead at the rear end. In a cell module assembly, multiple battery cells 250 may be arranged to be electrically connected to one another.

[0099] In this embodiment of the cell module assembly, the battery cells are stacked vertically, and multiple cell module assemblies can be arranged vertically within the module case 210.

[0100] Figure 16 shows a pouch-type battery cell 250.

[0101] The pouch-type battery cell 250 may include an electrode assembly and a cell case 255 that houses the electrode assembly.

[0102] The cell case 255 of the battery cell 250 is for housing the electrode assembly and may be a pouch-type cell case 255. The cell case 255 includes a lower case and an upper case that covers the lower case, and the upper case and lower case may be integrated. Also, as shown in Figure 16, the connecting portion of the upper case and lower case may be folded. And, as shown in the figure, the upper case may completely cover the lower case and a sealing portion 254 may be formed around the periphery.

[0103] Both the upper and lower cases can be laminate structures including an internal coating layer, a metal layer, and an external coating layer. The internal coating layer is located inside the cell case 255 relative to the metal layer and is in direct contact with the electrode assembly. Therefore, it must have insulating and electrolytic resistance properties, and in order to provide airtightness to the outside, it is required to have sealing properties, that is, the sealing portions where the internal layers are heat-bonded together must have excellent thermal bonding strength. The metal layer is located between the internal and external coating layers and acts as a barrier layer that prevents moisture and various gases from penetrating into the inside of the battery from the outside. A suitable material for the metal layer in contact with the internal coating layer is a thin film of aluminum (Al) which is lightweight yet has excellent moldability. The external coating layer is located outside the cell case 255 relative to the metal layer. Such an external coating layer can use a heat-resistant polymer with excellent tensile strength, moisture permeability prevention, and air permeability prevention properties so as to protect the electrode assembly while ensuring heat resistance and fire resistance. For example, nylon or polyethylene terephthalate can be used.

[0104] An accommodating groove 256 is formed in the upper case and the lower case, and the electrode assembly can be accommodated in the accommodating groove 256 of the upper case and the lower case. In the cell case 255 of the pouch-type battery cell 250, the part shown in Figure 16 is the upper case, and the lower case is positioned below it. In this embodiment, the lower case of the cell case 255 is positioned facing the bottom 3211 of the module case 210, and the lower case and its accommodating groove 256 may be positioned parallel to the bottom 211.

[0105] The electrode assembly housed in the cell case 255 may be one selected from the group consisting of a jelly roll type electrode assembly having a structure in which a separation membrane is interposed between a long sheet-like negative electrode and a positive electrode before it is wound up, a stack type electrode assembly consisting of unit cells having a structure in which rectangular positive and negative electrodes are stacked with a separation membrane in between, a stack-folding type electrode assembly in which the unit cells are wound up by a long separation film, and a lamination-stack type electrode assembly in which the unit cells are stacked with a separation membrane in between and adhere to each other.

[0106] The electrode assembly may also include two electrode tabs 250a and 250b, and two electrode leads 251 and 252 connected to these two electrode tabs 250a and 250b via welded joints.

[0107] One of the two electrode tabs 250a and 250b may be the positive electrode tab and the other may be the negative electrode tab.

[0108] One of the two electrode leads 251, 252 may be a positive lead connected to a positive tab, and the other electrode lead 251, 252 may be a negative lead connected to a negative tab. For example, the positive electrode leads 251, 252 may be made of aluminum (Al), and the negative electrode leads 251, 252 may be made of copper (Cu).

[0109] A lead film 253 can be attached to each of the electrode leads 251 and 252. The lead film 253 attached to the electrode leads 251 and 252 is located between the electrode leads 251 and 252 and the cell case 255, preventing short circuits from occurring between the electrode leads 251 and 252 and the cell case 255, improving sealing and preventing leakage of electrolyte.

[0110] Although the two electrode leads 251 and 252 are shown positioned on both sides of the electrode assembly, they may be positioned on only one side of the electrode assembly depending on the arrangement of the electrode tabs.

[0111] In a cell module assembly, the battery cells are not limited to pouch-type battery cells, but may consist of other forms of battery cells such as prismatic or cylindrical battery cells.

[0112] The cell module assembly may be located within the module case 210 of the battery module 200 in an open configuration without separate housings. Alternatively, as another example, the cell module assembly may have a configuration in which multiple battery cells are housed in housings, and the cell module assembly may be housed in individual housings and arranged independently within the module case 210.

[0113] As another example, the battery module 200 may consist of multiple battery cells stacked and arranged within a module case 210.

[0114] The module case 210 may include a bottom section 211, a front section 212, a rear section 214, two side sections 213 and 216, and a top section 215.

[0115] The bottom 211 of the module case 210 has a plate shape that extends horizontally and can form the bottom of the module case 210.

[0116] The front portion 212 and the rear portion 214 can form the front and rear surfaces of the module case 210, respectively, and can be positioned at the front and rear edges of the bottom portion 211 and the top portion 215, respectively.

[0117] The two side portions 213 and 216 form the two sides of the module case 210 and may be positioned on the left and right edges of the bottom portion 211 and the top portion 215, respectively.

[0118] The front section 212, the rear section 214, and both side sections 213 and 216 can form the sides of the module case 210.

[0119] The upper portion 215 is positioned on top of the module case 210 and can cover the inside of the module case 210.

[0120] In the module case 210, the area of ​​the side portions 213 and 216 may be larger than the area of ​​the bottom portion 211. For example, the area of ​​the side portions 213 and 216 may be more than twice the area of ​​the bottom portion 211. Therefore, as shown in the figure, in the module case 210, one side with a large area does not form the bottom but forms the side of the module case 210 and is arranged to stand upright, thereby reducing the installation area within the energy storage device 1000.

[0121] Multiple such battery modules 200 can be arranged on a support frame 300 within the case 100.

[0122] Figure 17 shows an energy storage device 1000 according to one embodiment of the present invention, and illustrates a support frame 300 that supports a battery module 200.

[0123] The support frame 300 can support multiple battery modules 200. In this embodiment, the support frame 300 may include multiple vertical support members 310, a lower support portion 320, an upper support portion 330, a top fixing member 340, and a module fixing member 350.

[0124] In this embodiment, four vertical support members 310 are arranged, with two vertical support members 310 positioned in front of the battery module 200 and two vertical support members 310 positioned behind the battery module 200.

[0125] The vertical support member 310 may include a pair of vane plates 311 and a connecting plate 312.

[0126] A connecting plate 312 positioned between a pair of vanes 311 can connect the pair of vanes 311. The pair of vanes 311 and the connecting plate 312 are integrally formed, and the pair of vanes 311 can be bent outward from both ends of the connecting plate 312 at a certain angle (e.g., a right angle) (towards the opposite side of the battery module 200) by a vertical support member 310 and arranged parallel to each other.

[0127] Each wing plate 311 may have multiple through holes 313 spaced apart along its longitudinal direction.

[0128] The vertical support member 310 can be reinforced in terms of structural rigidity by having a pair of bent wing plates 311 positioned on both sides of the connecting plate 312 in this manner.

[0129] The lower support portion 320 is positioned below the support frame 300 and can support multiple battery modules 200.

[0130] In this embodiment, two battery modules 200 are shown being supported by the lower support portion 320, but two or more battery modules 200 may be arranged on the lower support portion 320.

[0131] The lower support section 320 may include a support plate 321 and two horizontal members 322 (see Figure 19).

[0132] The support plate 321 is a roughly rectangular plate on which the battery module 200 can be supported. A bent plate 321b is integrally formed on the edge of the support plate 321 in the width direction (X-axis direction), and the support plate 321b can be fixed by bolts or the like to two vertical support members 310 located behind the battery module 200 through coupling holes 321c formed in the bent plate 321b. The support plate 321 can be connected to the vertical support members 310 by bolts, rivets, welding, etc. The material of the support plate 321 may be, for example, a metal material.

[0133] A sheet 323 may be placed on the support plate 321.

[0134] The sheet 323 can be bonded to the support plate 321 or attached with an adhesive, and may be made of resin, polycarbonate, or other materials. A polycarbonate sheet as the sheet 323 has excellent electrical insulation, durability, weather resistance, and impact resistance, and can stably support a high-to-medium capacity battery module 200.

[0135] According to this embodiment, since the sheet 323 is placed on the support plate 321, when a high-to-medium capacity battery module 200 is placed on the support plate 321, friction is reduced, making it easier to install the battery module 200 and preventing scratches between contact parts.

[0136] The area of ​​sheet 323 may be the same as or smaller than the area of ​​support plate 321, and may be larger than the sum of the areas of the bottoms 211 of the two battery modules 200.

[0137] The support plate 321 may include side portions 321a that are bent downward from both ends in the longitudinal direction (Y-axis direction). The length of the side portions 321a in the longitudinal direction (Y-axis direction) may be the same as the length of the support plate 321.

[0138] The two horizontal members 322 may be formed by bending (for example, at a right angle) from the end of the side portion 321a toward the support plate 321. The horizontal members 322 may be parallel to the support plate 321.

[0139] The horizontal members 322 are formed integrally with the support plate 321, and one end of each horizontal member 322 can be connected to the lower part of a vertical support member 310 positioned in front of the battery module 200. The horizontal members 322 can be connected to the vertical support member 310 by bolts, rivets, welding, etc.

[0140] Furthermore, the horizontal member 322 is formed in a plate shape and can extend and protrude beyond the support plate 321 in the longitudinal direction (Y-axis direction). Therefore, the length of the horizontal member 322 in the longitudinal direction (Y-axis direction) may be longer than that of the support plate 321. Thus, a space S can be formed between the front portion of the battery module 200 placed on the support plate 321 and the vertical support member 310 coupled to the horizontal member 322. In this embodiment, by securing a space S inside the vertical support member 310 in this way, insertion and assembly of the battery module 200 become easier, and electrical work, as well as the installation of electrical devices and wiring, becomes easier (see Figure 15).

[0141] The lower support portion 320 can be integrally formed with the support plate 321, the side portion 321a, and the horizontal member 322.

[0142] The lower support portion 320 is arranged by bending the side portions 321a from both ends of the support plate 321, and by bending the horizontal member 322 from the side portions 321a, thereby providing rigidity and stably supporting the high-to-medium capacity battery module 200.

[0143] The upper support portion 330 is positioned above the lower support portion 320 of the support frame 300 and can support multiple battery modules 200. In this embodiment, the upper support portion 330 is positioned between the lower support portion 320 and the top fixing member 340 and can be connected to the approximately central part of the vertical support member 310.

[0144] The configuration of the upper support section 330 is almost identical to that of the lower support section 320. Although the drawing shows two battery modules 200 supported by the upper support section 330, two or more battery modules 200 can also be arranged on the upper support section 330.

[0145] The upper support portion 330 may include a support plate 331 and two horizontal members 332 (see Figure 20).

[0146] In the upper support portion 330, the support plate 331 may be made of a substantially rectangular plate. A bent plate 331b is integrally formed on the edge of the support plate 331 in the width direction (X-axis direction), and it can be fixed by bolts or the like to two vertical support members 310 located behind the battery module 200 through coupling holes 331c formed in the bent plate 331b. The support plate 331 can be made of a metal material, for example, and can be connected to the vertical support members 310 by bolts, rivets, welding, etc.

[0147] A sheet 333 may be placed on the support plate 331. The sheet 333 can be bonded to the support plate 321 or attached with an adhesive, and may be made of resin, polycarbonate, or the like.

[0148] In the upper support portion 330, as with the lower support portion 320, the sheet 333 is placed on the support plate 331. This reduces friction when a high-to-medium capacity battery module 200 is placed on the support plate 331, making it easier to install the battery module 200.

[0149] The area of ​​sheet 333 may be the same as or smaller than the area of ​​support plate 331, and may be larger than the sum of the areas of the bottoms 211 of the two battery modules 200.

[0150] Side portions 331a may be bent downwards from both ends of the support plate 331 in the longitudinal direction (Y-axis direction). The length of the side portions 331a in the longitudinal direction (Y-axis direction) may be the same as that of the support plate 331.

[0151] The two horizontal members 332 may be formed by bending (for example, at a right angle) the ends of the side portion 331a toward the support plate 321. The horizontal members 332 may also be parallel to the support plate 331.

[0152] In the upper support portion 330, the horizontal members 332 are integrally formed with the support plate 331, and one end of each horizontal member 332 can be connected to the central part of the vertical support member 310 positioned in front of the battery module 200 by bolts, rivets, welding, etc.

[0153] Furthermore, the horizontal member 332 is formed in a plate shape and can extend and protrude beyond the support plate 331 in the longitudinal direction (Y-axis direction). Therefore, the length of the horizontal member 332 in the longitudinal direction (Y-axis direction) may be longer than that of the support plate 331. Thus, a space S is formed between the front portion of the battery module 200 placed on the support plate 331 and the vertical support member 310 connected to the horizontal member 332, and by securing space S inside the vertical support member 310, insertion and assembly of the battery module 200 become easier, and electrical work becomes easier.

[0154] In the upper support portion 330, the support plate 331, the side portion 331a, and the horizontal member 332 can be formed integrally.

[0155] The upper support portion 330 is formed by bending the side portions 331a from both ends of the support plate 331 and then bending the horizontal member 332 from the side portions 331a, thereby providing rigidity and stably supporting the high-to-medium capacity battery module 200.

[0156] The top fixing member 340 is positioned on the upper part of the support frame 300 and can serve to fix and support the upper end of the support frame 300.

[0157] The top fixing member 340 may include two fixing members 341 and two connecting members 342.

[0158] With the top fixing member 340, one end of the fixing member 341 can be connected to the front vertical support member 310 of the battery module 200, and the other end of the fixing member 341 can be connected to the rear vertical support member 310 of the battery module 200. The two fixing members 341 can be arranged parallel to each other. The fixing members 341 can be connected to the vertical support member 310 by bolts, rivets, welding, etc.

[0159] One end of the connecting member 342 is connected to one fixing member 341, and the other end is connected to another fixing member 341, thereby connecting two fixing members 341 to each other. The two connecting members 342 can be spaced apart along the longitudinal direction (Y-axis direction) of the fixing member 341 and can be arranged parallel to each other.

[0160] In this way, the two fixing members 341 can connect to each other the two vertical support members 310 which are positioned in the front and rear of the battery module 200, and the two connecting members 342 can connect to each other the two fixing members 341, so that the top fixing member 340 can fix and support the upper end of the support frame 300.

[0161] In this embodiment, the module fixing member 350 is connected to the vertical support member 310, fixing the two battery modules 200 and preventing movement and vibration.

[0162] As shown in the figure, upper and lower module fixing members 350 are positioned on two vertical support members 310 at the rear of the battery module 200. The lower module fixing member 350 can fix two battery modules 200 positioned on the lower support portion 320, and the upper module fixing member 350 can fix two battery modules 200 positioned on the upper support portion 330.

[0163] The module fixing member 350 may include a coupling plate 351 that is coupled to and fixed to two vertical support members 310, and the rear portions of two battery modules 200 can be supported by the coupling plate 351.

[0164] In this embodiment, the rigidity of the structure can be stably ensured because the support frame 300 has the configuration described above. Furthermore, the energy storage device 1000 according to this embodiment has a reduced installation area and a thinner thickness (distance in the X-axis direction).

[0165] As described above, the present invention has been described based on preferred embodiments, but it is not limited to the embodiments described above, and various modifications and alterations are possible by persons with ordinary skill in the art to which the present invention belongs, without departing from the technical spirit of the present invention.
