Description

Wall-mounted mounting structure for energy storage devices

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

[0002] Secondary batteries, unlike primary batteries that cannot be recharged, are batteries that can be charged and discharged. They are used not only in portable devices but also in electric vehicles (EVs) and hybrid electric vehicles (HEVs) that are driven by electrical power sources.

[0003] Currently, widely used types of secondary batteries include lithium-ion batteries, lithium polymer batteries, nickel-cadmium batteries, nickel-metal hydride batteries, and nickel-zinc batteries. The operating voltage of these unit secondary battery cells, i.e., unit battery cells, is approximately 2.5 V to 4.6 V. Therefore, when a higher output voltage is required, multiple battery cells are connected in series to form a battery pack. Furthermore, depending on the charge / discharge capacity required for the battery pack, multiple battery cells are connected in parallel to form a battery pack. Therefore, the number of battery cells included in the battery pack can be set in various ways depending on the required output voltage or charge / discharge capacity.

[0004] When configuring a battery pack by connecting multiple battery cells in series or parallel, it is common to first configure a battery module comprising at least one battery cell, preferably multiple battery cells, and then use at least one such battery module and add other components to configure the battery pack. Here, the battery module refers to a component in which multiple battery cells are connected in series or parallel, and the battery pack may refer to a component in which multiple battery modules are connected in series or parallel to increase capacity and output.

[0005] Recently, energy storage devices are being used to store generated electricity, and the energy storage devices can be configured to include multiple battery modules.

[0006] Energy storage devices are small and can be used for domestic purposes, and for such small energy storage devices, separate mounting methods may be required.

[0057] 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).

[0058] The above case (100) forms an outer case of an energy storage device (1000), can accommodate a plurality of battery modules (200) and a support frame (300), and can include a main body (110) and a door (120).

[0059] In the 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 an upper portion (115).

[0060] The bottom part (111) of the main body (110) can be formed in the form of a plate extending horizontally. On the outer lower surface of the bottom part (111), four support legs (111a) for supporting the case (100) can be respectively arranged at the corners of the bottom part (111).

[0061] In the main body (110), the front part (112) and the rear part (114) can form the front and rear of the case (100), respectively, and can be arranged at the front and rear edges of the bottom part (111) and the upper surface part (115), respectively.

[0062] In the main body (110), the side portion (113) forms one side of the case (100) and can be placed on the left or right edge of the bottom portion (111) and the upper surface portion (115), respectively.

[0063] The front part (112), the rear part (114), and the side part (113) can form the side of the case (100) together with the door (120).

[0064] In the main body (110), the upper surface (115) may be placed on the upper part of the case (100) and may cover the inside of the case (100). An electrical device such as a PCS (Power Conversion System) may be installed on the outer upper surface of the upper surface (115), and may have a structure for installing the electrical device.

[0065] The door (120) is coupled to one side of the main body (110) and can open and close the interior of the case (100). The door (120) can be positioned on the opposite side of the side portion (113) of the case (100) to face the side portion (113) and form one side of the case (100).

[0066] The door (120) can be rotatably connected to the main body (110) by a hinge, and can also be connected to the main body (110) so as to be completely detachable from the main body (110).

[0067] In one embodiment of the present invention, a locking device for the door (120) may be provided.

[0068] In the case (100), the areas of the side portion (113) and the door (120) may be the same or similar to each other, 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 that of the bottom portion (111), and therefore, as illustrated, one side with a large area in the case (100) of the energy storage device (1000) may be arranged in a form in which it stands up by forming the side of the case (100) rather than forming the bottom, thereby reducing the installation area.

[0069] In one embodiment of the present invention, an energy storage device (1000) may be mounted on a wall (W) by being coupled to a wall-mounted bracket (500). FIGS. 3 to 11 are drawings for explaining a wall-mounted mounting structure in one embodiment of the present invention.

[0070] A wall mounting bracket (500) can be fixed to a wall (W) to support an energy storage device (1000).

[0071] The wall-mounted bracket (500) includes a plurality of connecting holes (510) as illustrated in FIG. 3. A fixing member (511) is connected to each connecting hole (510), and the wall-mounted bracket (500) can be fixed to a wall (W) by the fixing member (511). The fixing member (511) connected to the connecting hole (510) can be a screw, a nail, an anchor, an anchor bolt, or the like.

[0072] In this embodiment, the joining hole (510) can extend in the horizontal direction (Y-axis direction). Since the joining hole (510) extends in the width direction (Y-axis direction) of the wall-mounted bracket (500), the fixing position of the fixing member (511) within the joining hole (510) can be adjusted. As illustrated, a plurality of joining holes (510) can be arranged on the left and right sides of the wall-mounted bracket (500) and can also be arranged on the upper and lower sides.

[0073] The wall bracket (500) may include a rack bracket (550).

[0074] The rack bracket (550) is intended to support a coupling bracket (150) placed at the rear of the energy storage device (1000), and can be extended in the width direction (Y-axis direction) of the wall-mounted bracket (500).

[0075] The rack bracket (550) may include a coupling portion (551) that is coupled to the wall bracket (500), a support portion (552), and an upward extension portion (553) (see FIGS. 3 and 10).

[0076] The connecting portion (551) can be formed by bending upward from the rear end of the support portion (552), and the connecting portion (551) can be connected to the wall-mounted bracket (500) by welding or the like.

[0077] In this embodiment, the connecting portion (551) can be placed on both left and right sides of the wall-mounted bracket (500).

[0078] The support member (552) can be formed to extend 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.

[0079] As shown in FIGS. 9 and 10, the support member (552) can support the support protrusion (155) of the coupling bracket (150) from below.

[0080] The upper extension (553) can be arranged on both sides of the support (552) and can be formed by bending upward from the front end of the support (552).

[0081] The upward extension portion (553) can support one side of the support protrusion (155), and can support the support protrusion (155) together with the support portion (552) as illustrated in FIG. 10. The upward extension portion (553) extends upward from one end of the support portion (552) to support one side of the support protrusion (155), thereby preventing the support protrusion (155) from being separated in the forward direction (X-outward direction) from the wall-mounted bracket (500).

[0082] The upper end of the upper extension (553) can be formed to be bent forward as shown in Fig. 10. By forming the upper end of the upper extension (553) to be bent forward as shown in Fig. 8, when the support protrusion (155) of the coupling bracket (150) is moved downward to be coupled to the rack bracket (550), the support protrusion (155) can be easily moved inside the upper extension (553).

[0083] The connecting portion (551), the supporting portion (552), and the upward extension portion (553) constituting the rack bracket (550) can be formed integrally.

[0084] Rack brackets (550) can be placed on the upper and lower portions of the wall-mounted bracket (500), and support protrusions (155) can be supported on each rack bracket (550).

[0085] Accordingly, the energy storage device (1000) can be mounted on the wall bracket (500) by hanging the coupling bracket (150) placed on the rear of the energy storage device (1000) on the rack bracket (550).

[0086] Wing plates (530) can be placed on each side of the wall-mounted bracket (500).

[0087] The wing plates (530) may be formed by being bent forward from both sides of the wall-mounted bracket (500). As illustrated in FIG. 3, each wing plate (530) may include a protruding plate (531) and a joining hole (532), and the joining hole (532) may be formed in the protruding plate (531). A joining member (151b) for joining the joining bracket (150) and the wall-mounted bracket (500) may be inserted into the joining hole (532).

[0088] The protrusion plate (531) may be formed to be convex outward in a certain area on the wing plate (530), and the entire thickness of the wing plate (530) may protrude outward in the area of ​​the protrusion plate (531).

[0089] The protruding plate (531) formed convexly outwardly on the wing plate (530) can contact the outer plate (151) of the coupling bracket (150). A coupling member (151b) sequentially passes through the coupling hole (151a) formed on the outer plate (151) of the coupling bracket (150) and the coupling hole (532) of the wing plate (530) and can be screw-connected with a nut (not shown) on the inside of the protruding plate (531). The nut (not shown) to which the coupling member (151b) is connected can be placed on the inner surface of the protruding plate (531) (the opposite surface of the surface of the protruding plate (531) facing the outer plate (151), and can also be fixed to the inner surface of the protruding plate (531) by welding, etc. In this way, the protruding plate (531) protrudes from the wing plate (530) and is in contact with the outer plate (151), and can be tightened using the connecting member (151b), thereby firmly connecting the wing plate (530) and the outer plate (151). The connecting member (151b) may be a bolt or the like.

[0090] In the wing plate (530), a plurality of protrusion plates (531) and connecting holes (532) can be arranged in the vertical direction (Z direction).

[0091] As shown, a plurality of holes (501) may be formed in the wall-mounted bracket (500). By forming a plurality of holes (501) in the wall-mounted bracket (500), the self-load of the wall-mounted bracket (500) can be reduced and air circulation can be facilitated, thereby helping to cool the energy storage device (1000).

[0092] The coupling brackets (150) arranged on the rear side (rear side of the side part (113)) of the case (100) main body (110) can be arranged on the left and right sides of the rear side of the main body (110) as shown in FIG. 5.

[0093] Each coupling bracket (150) can extend vertically (Z-axis direction) from the edge of the rear surface of the main body (110) and can include a coupling plate (152), an outer plate (151), and an inner plate (153).

[0094] The joining plate (152) can extend vertically along the edge of the rear surface of the main body (110) and can be joined to the rear surface of the main body (110) by welding or the like.

[0095] The outer plate (151) can be formed by bending backwards (towards the wall-mounted bracket (500)) from the outer end of the connecting plate (152), and a plurality of connecting holes (151a) can be formed along the vertical direction. The connecting member (151b) inserted into the connecting hole (151a) can be connected to the connecting hole (532) of the wing plate (530) to connect the outer plate (151) and the wing plate (530).

[0096] The inner plate (153) can be formed by bending backward (toward the wall-mounted bracket (500)) from the inner end of the joining plate (152) and can be arranged to face the outer plate (151) and can be arranged parallel to the outer plate (151).

[0097] A support protrusion (155) may be arranged on the inner plate (153). The support protrusion (155) may be formed to extend downward, and as described above, the support protrusion (155) may be supported on the rack bracket (550) so that the energy storage device (1000) may be mounted on the wall bracket (500).

[0098] The support protrusions (155) can be positioned on the upper and lower sides, respectively, and the support protrusions (155) on the upper and lower sides can be connected to the upper and lower rack brackets (550) of the wall-mounted bracket (500), respectively.

[0099] Figures 6 to 11 are drawings illustrating a process of mounting an energy storage device (1000) on a wall-mounted bracket (500).

[0100] As shown in Fig. 6, when the energy storage device (1000) is separated from the wall-mounted bracket (500), the energy storage device (1000) can be moved toward the wall-mounted bracket (500) and the energy storage device (1000) can be brought into close contact with the wall-mounted bracket (500). At this time, the support protrusion (155) of the coupling bracket (150) is positioned above the rack bracket (550).

[0101] Next, as shown in FIGS. 7 and 8, the energy storage device (1000) is lowered along the wall so that the support protrusion (155) of the coupling bracket (150) disposed on the rear side (side surface (113)) of the case (100) body (100) of the energy storage device (1000) is supported by the rack bracket (550) of the wall-mounted bracket (500). At this time, the wing plate (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 protrusion (155) of the coupling brackets (150) on both sides is supported by the support portion (552) on the inner side of the upward extension portion (553) of the rack bracket (550).

[0102] Figure 10 is a detailed drawing showing a state in which a support protrusion (155) of a coupling bracket (150) is supported by a rack bracket (550) of a wall-mounted bracket (500).

[0103] In this way, the support protrusions (155) positioned on the upper and lower sides of the coupling bracket (150) are supported by the rack brackets (550) positioned on the upper and lower sides of the wall-mounted bracket (500), and the coupling bracket (150) is fixed to the wall-mounted bracket (500) using a coupling member (151b).

[0104] Fixing the coupling bracket (150) to the wall-mounted bracket (500) using the coupling member (151b) can be accomplished 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) of the wing plate (530) and screwing it with a nut (not shown) inside the coupling hole (532).

[0105] By tightening the connecting member (151b) in this way to firmly fix the connecting bracket (150) to the wall-mounted bracket (500), the mounting of the energy storage device (1000) on the wall-mounted bracket (500) is completed.

[0106] As described above, in the wall-mounted mounting structure of the energy storage device (1000) according to the present embodiment, structural rigidity for supporting the energy storage device (1000) can be secured, the energy storage device (1000) is hung on a wall-mounted bracket (500) fixed to a wall (W), making installation easy, and eliminating the need for a structure for supporting the bottom of the energy storage device (1000). In addition, in the present 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) by a coupling member (151b), thereby preventing rearward movement of the energy storage device (1000) and improving earthquake resistance.

[0107] FIG. 12 is a drawing illustrating a wall-mounted mounting structure of an energy storage device (1000) according to another embodiment, and is a partial plan view of an energy storage device (1000) coupled to a wall-mounted bracket (500).

[0108] In another embodiment illustrated in FIG. 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).

[0109] The extension support plate (154) can be bent from the inner plate (153) of the coupling bracket (150) toward the outer plate (151) and extended along the wall-mounted bracket (500). The extension support plate (154) can contact the wall-mounted bracket (500) and be supported by the wall-mounted bracket (500).

[0118] The battery module (200) may include a module case (210) as shown in FIGS. 14 and 15, and a plurality of cell module assemblies (CMAs (Cell Module Assemblies)) (not shown) accommodated within the module case (210).

[0119] A cell module assembly (CMA) accommodated in a module case (210) comprises a plurality of battery cells, and in each cell module assembly, a plurality of battery cells can be arranged in close contact.

[0120] 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 accommodated within a pouch-type case.

[0121] For example, a cell module assembly may include a plurality of battery cells that are mutually stacked or closely packed, and each battery cell may be provided with electrode leads (251, 252) at the front and / or rear ends, and a positive electrode lead may be provided at the front end and a negative electrode lead may be provided at the rear end. In the cell module assembly, a plurality of battery cells (250) may be arranged so as to be electrically connected to each other.

[0122] In the cell module assembly of the present embodiment, battery cells can be stacked vertically, and a plurality of cell module assemblies can be arranged vertically within a module case (210).

[0123] Figure 16 is a drawing illustrating a pouch-type battery cell (250).

[0124] A battery cell (250) provided in a pouch type may include an electrode assembly and a cell case (255) that accommodates the electrode assembly.

[0125] The cell case (255) of the battery cell (250) may be a pouch-type cell case (255) for accommodating the electrode assembly. The cell case (255) includes a lower case and an upper case covering the lower case, and the upper and lower cases may be formed as a single body. In addition, as illustrated in FIG. 16, the connecting portions of the upper and lower cases may be formed in a structure in which they are bent and folded. In addition, as illustrated, the upper case may completely cover the lower case, and a sealing portion (254) may be formed at the periphery.

[0126] Both the upper and lower cases can be formed of a laminate structure including an inner covering layer, a metal layer, and an outer covering layer. The inner covering layer is located on the inside of the cell case (255) based on the metal layer and is in direct contact with the electrode assembly, so it must have insulation and electrolytic resistance. In addition, in order to seal it from the outside, the sealing portion where the inner layers are thermally bonded must have excellent thermal bonding strength. The metal layer is located between the inner covering layer and the outer covering layer and serves as a barrier layer that prevents moisture or various gases from penetrating into the battery from the outside. A preferable material for the metal layer in contact with the inner covering layer is an aluminum (Al) thin film that is lightweight and has excellent formability. The outer covering layer is located on the outside of the cell case (255) based on the metal layer, and this outer covering layer can use a heat-resistant polymer with excellent tensile strength, moisture permeability, and air permeability to protect the electrode assembly while ensuring heat resistance and chemical resistance. For example, nylon or polyethylene terephthalate can be used.

[0127] A receiving groove (256) may be formed in each of the upper and lower cases, and an electrode assembly may be accommodated in the receiving groove (256) of the upper and lower cases. In the cell case (255) of the pouch-type battery cell (250), the part shown in FIG. 16 is the upper case, and the lower case is arranged below it. In the present embodiment, the lower case of the cell case (255) may be arranged to face the bottom portion (3211) of the module case (210), and the lower case and its receiving groove (256) may be arranged parallel to the bottom portion (211).

[0128] The electrode assembly housed in the cell case (255) may be one of a group consisting of a jelly-roll type electrode assembly having a structure in which a separator is interposed between long sheet-shaped positive and negative electrodes and then rolled up, a stack type electrode assembly having unit cells having a structure in which rectangular positive and negative electrodes are stacked with a separator interposed between them, a stack-folding type electrode assembly in which the unit cells are rolled up by a long separator film, and a lamination-stack type electrode assembly in which the unit cells are stacked with a separator interposed between them and attached to each other.

[0129] Additionally, the electrode assembly may include two electrode tabs (250a, 250b) and two electrode leads (251, 252) connected to the two electrode tabs (250a, 250b) by welding, respectively.

[0130] One of the two electrode tabs (250a, 250b) may be a positive tab and the other may be a negative tab.

[0131] Among the two electrode leads (251, 252), one electrode lead (251, 252) may be a positive lead connected to the positive tab, and the other electrode lead (251, 252) may be a negative lead connected to the negative tab. For example, the positive electrode lead (251, 252) may be made of aluminum (Al), and the negative electrode lead (251, 252) may be made of copper (Cu).

[0132] A lead film (253) may be attached to each of the electrode leads (251, 252). The lead film (253) attached to the electrode leads (251, 252) is positioned between the electrode leads (251, 252) and the cell case (255) to prevent a short circuit from occurring between the electrode leads (251, 252) and the cell case (255) and to improve sealing strength, thereby preventing leakage of the electrolyte, etc.

[0133] The two electrode leads (251, 252) are shown as being arranged on each side of the electrode assembly, but may be arranged on only one side of the electrode assembly depending on the arrangement of the electrode tabs.

[0134] In the cell module assembly, the battery cells are not limited to pouch-shaped battery cells, but may be composed of other shapes such as square or cylindrical battery cells.

[0135] The cell module assembly may be placed within the module case (210) of the battery module (200) in an open form without an independent housing. In addition, as another example, the cell module assembly may be in a form in which a plurality of battery cells are housed within a housing, and the cell module assembly may be housed within individual housings and placed independently within the module case (210).

[0136] As another example, the battery module (200) may have multiple battery cells stacked and arranged within a module case (210).

[0137] The module case (210) may include a bottom portion (211), a front portion (212), a rear portion (214), two side portions (213, 216), and a top portion (215).

[0138] The bottom part (211) of the module case (210) can form the bottom of the module case (210) in the form of a plate extending in a horizontal direction.

[0139] The front part (212) and the rear part (214) can form the front and rear parts of the module case (210), respectively, and can be arranged at the front and rear edges of the bottom part (211) and the upper surface part (215), respectively.

[0140] The two side portions (213, 216) form both sides of the module case (210) and can be placed on the left and right edges of the bottom portion (211) and the top portion (215), respectively.

[0141] The front portion (212), the rear portion (214), and both side portions (213, 216) can form the side surfaces of the module case (210).

[0142] The upper surface (215) can be placed on the upper part of the module case (210) and cover the inside of the module case (210).

[0143] In the module case (210), the area of ​​the side portions (213, 216) may be larger than the area of ​​the bottom portion (211). For example, the area of ​​the side portions (213, 216) may be more than twice that of the bottom portion (211), and therefore, as illustrated, one side of the module case (210) with a large area may not form the bottom, but may be arranged to form a side of the module case (210) and stand up, thereby reducing the installation area within the energy storage device (1000).

[0144] These multiple battery modules (200) can be placed on a support frame (300) within a case (100).

[0145] FIG. 17 is a drawing illustrating a support frame (300) that supports a battery module (200) in an energy storage device (1000) according to one embodiment of the present invention.

[0146] The above support frame (300) can support a plurality of battery modules (200). In the present embodiment, the support frame (300) can include a plurality of vertical support members (310), a lower support member (320), an upper support member (330), a top fixing member (340), and a module fixing member (350).

[0147] In this embodiment, four vertical support members (310) can be arranged, two vertical support members (310) can be arranged in front of the battery module (200), and two vertical support members (310) can be arranged in the rear of the battery module (200).

[0148] The vertical support member (310) may include a pair of wing plates (311) and a connecting plate (312).

[0149] A connecting plate (312) disposed between a pair of wing plates (311) can connect the pair of wing plates (311). The pair of wing plates (311) and the connecting plate (312) can be formed integrally, and the pair of wing plates (311) in the vertical support member (310) can be bent outwardly (in the opposite direction of the battery module (200)) at a certain angle (for example, a right angle) from both ends of the connecting plate (312) and can be disposed parallel to each other.

[0150] Each wing plate (311) may have a plurality of apertures (313) spaced apart from each other along the length.

[0151] The vertical support member (310) can have its structural rigidity reinforced by having a pair of wing plates (311) bent on both sides of the connecting plate (312).

[0152] The lower support member (320) is arranged on the lower side of the support frame (300) and can support a plurality of battery modules (200).

[0153] In this embodiment, two battery modules (200) are shown to be supported by the lower support member (320), but two or more battery modules (200) may be placed on the lower support member (320).

[0154] The lower support (320) may include a support plate (321) and two horizontal members (322) (see FIG. 19).

[0155] The support plate (321) may be formed as a plate having an approximately rectangular shape, and the battery module (200) may be supported on the support plate (321). The support plate (321) may be integrally formed with a folded plate (321b) that is folded upward along an edge in the width direction (X-axis direction) of the support plate (321), and may be fixed by being joined to two vertical support members (310) arranged at the rear of the battery module (200) through a joining hole (321c) formed in the folded plate (321b) using a bolt or the like. The support plate (321) may be joined to the vertical support members (310) by a bolt, a rivet, welding, or the like. The material of the support plate (321) may be, for example, metal.

[0156] A sheet (323) can be placed on the support plate (321).

[0157] The sheet (323) can be bonded to or attached with an adhesive on the support plate (321), and can be, for example, a resin sheet, a polycarbonate sheet, etc. As the sheet (323), the polycarbonate sheet has excellent electrical insulation, durability, weather resistance, impact resistance, etc., and can stably support a heavy battery module (200).

[0158] In this embodiment, a sheet (323) is placed on a support plate (321), so that when a heavy 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 contacting parts.

[0159] The area of ​​the sheet (323) may be equal to or smaller than the area of ​​the support plate (321), and may be larger than the sum of the areas of the bottoms (211) of the two battery modules (200).

[0160] It may include two side portions (321a) that are bent downward at both ends of the support plate (321) along the longitudinal direction (Y-axis direction). The length of the side portions (321a) along the longitudinal direction (Y-axis direction) may be the same as that of the support plate (321).

[0161] Two horizontal members (322) can be formed by bending (for example, bending at a right angle) toward the support plate (321) at the end of the side portion (321a). The horizontal members (322) can be parallel to the support plate (321).

[0162] The horizontal member (322) may be formed integrally with the support plate (321), and one end of each horizontal member (322) may be joined to the lower portion of the vertical support member (310) positioned at the front of the battery module (200). The horizontal member (322) may be joined to the vertical support member (310) using bolts, rivets, welding, or the like.

[0163] In addition, the horizontal member (322) may be formed in a plate shape and may extend and protrude further than the support plate (321) in the longitudinal direction (Y-axis direction). Accordingly, the length of the horizontal member (322) in the longitudinal direction (Y-axis direction) may be longer than that of the support plate (321). Accordingly, a space (S) may be formed between the front portion of the battery module (200) disposed on the support plate (321) and the vertical support member (310) coupled to the horizontal member (322). In the present embodiment, by securing the space (S) inside the vertical support member (310) in this way, the insertion and assembly of the battery module (200) is facilitated, and electrical work is facilitated along with the installation of electrical devices and wiring (see FIG. 15).

[0164] In the lower support member (320), the support plate (321), the side member (321a), and the horizontal member (322) can be formed integrally.

[0165] The lower support member (320) is bent at both ends of the support plate (321) to place the side member (321a), and the horizontal member (322) is bent at the side member (321a) to place the horizontal member, thereby reinforcing the rigidity and stably supporting the heavy battery module (200).

[0166] The upper support member (330) may be positioned above the lower support member (320) in the support frame (300) to support a plurality of battery modules (200). In the present embodiment, the upper support member (330) may be positioned between the lower support member (320) and the top fixing member (340), and may be coupled to the vertical support member (310) at approximately the center.

[0167] The configuration of the upper support (330) is similar to that of the lower support (320). Although the drawing shows two battery modules (200) being supported on the upper support (330), two or more battery modules (200) may be placed on the upper support (330).

[0168] The upper support member (330) may include a support plate (331) and two horizontal members (332) (see FIG. 20).

[0169] In the upper support member (330), the support plate (331) may be formed as a plate having an approximately square shape. A folded plate (331b) folded upward along the edge of the width direction (X-axis direction) of the support plate (331) may be integrally formed on the support plate (331), and may be fixed by being joined to two vertical support members (310) arranged at the rear of the battery module (200) using bolts or the like through a joining hole (331c) formed in the folded plate (331b). The support plate (331) may be made of, for example, a metal material, and may be joined to the vertical support members (310) by means of bolts, rivets, welding, or the like.

[0170] A sheet (333) may be placed on the support plate (331). The sheet (333) may be bonded to the support plate (321) or attached with an adhesive, and may be, for example, a resin sheet, a polycarbonate sheet, or the like.

[0171] Similarly to the lower support (320), a sheet (333) is placed on the support plate (331) on the upper support (330), so that friction is reduced when placing a heavy battery module (200) on the support plate (331), thereby facilitating installation of the battery module (200).

[0172] The area of ​​the sheet (333) may be equal to or smaller than the area of ​​the support plate (331), and may be larger than the sum of the areas of the bottoms (211) of the two battery modules (200).

[0173] A side portion (331a) may be arranged by bending downwards at both ends of the support plate (331) along the longitudinal direction (Y-axis direction). The length of the side portion (331a) along the longitudinal direction (Y-axis direction) may be the same as that of the support plate (331).

[0174] Two horizontal members (332) can be formed by bending (for example, bending at a right angle) from the end of the side portion (331a) toward the support plate (321). The horizontal members (332) can be parallel to the support plate (331).

[0175] In the upper support member (330), the horizontal member (332) can be formed integrally with the support plate (331), and one end of each horizontal member (332) can be connected to the central portion of the vertical support member (310) arranged in front of the battery module (200) using a bolt, rivet, welding, or the like.

[0176] In addition, the horizontal member (332) may be formed in a plate shape and may extend and protrude further than the support plate (331) in the longitudinal direction (Y-axis direction). Accordingly, the length of the horizontal member (332) in the longitudinal direction (Y-axis direction) may be longer than that of the support plate (331). Accordingly, a space (S) may be formed between the front portion of the battery module (200) disposed on the support plate (331) and the vertical support member (310) coupled to the horizontal member (332), and by securing the space (S) inside the vertical support member (310), insertion and assembly of the battery module (200) are facilitated, and electrical work is facilitated.

[0177] In the upper support member (330), the support plate (331), the side member (331a), and the horizontal member (332) can also be formed integrally.

[0178] The upper support member (330) is bent at both ends of the support plate (331) to place the side member (331a), and the horizontal member (332) is bent at the side member (331a) to place the horizontal member, thereby reinforcing the rigidity and stably supporting the heavy battery module (200).

[0179] The above top fixing member (340) can be placed on the upper part of the support frame (300) and can serve to fix and support the upper part of the support frame (300).

[0180] The top fixing member (340) may include two fixing members (341) and two connecting members (342).

[0181] In the top fixing member (340), one end of the fixing member (341) may be coupled to the vertical support member (310) at the front of the battery module (200), and the other end of the fixing member (341) may be coupled to the vertical support member (310) at the rear of the battery module (200). The two fixing members (341) may be arranged parallel to each other. The fixing member (341) may be coupled to the vertical support member (310) by means of a bolt, a rivet, welding, or the like.

[0182] A connecting member (342) may have one end connected to one fixed member (341) and the other end connected to another fixed member (341) so as to connect two fixed members (341) to each other. The two connecting members (342) may be spaced apart from each other along the longitudinal direction (Y-axis direction) of the fixed member (341) and may be arranged parallel to each other.

[0183] In this way, the two fixing members (341) can connect the two vertical support members (310) arranged at the front and rear of the battery module (200), respectively, and the two connecting members (342) can connect the two fixing members (341) to each other, so that the top fixing member (340) can fix and support the upper end of the support frame (300).

[0184] In this embodiment, the module fixing member (350) is coupled to the vertical support member (310) to fix two battery modules (200) and prevent movement and vibration.

[0185] As shown, upper and lower module fixing members (350) can be placed on two vertical support members (310) at the rear of the battery module (200), and the lower module fixing member (350) can fix two battery modules (200) placed on the lower support member (320), and the upper module fixing member (350) can fix two battery modules (200) placed on the upper support member (330).

[0186] The module fixing member (350) may include a joining plate (351) that is joined and fixed to two vertical support members (310), and the rear of the two battery modules (200) may be supported by the joining plate (351).

[0187] In this embodiment, the support frame (300) has the configuration described above, thereby stably securing the rigidity of the structure. In addition, the energy storage device (1000) according to this embodiment has a reduced installation area and a thinner thickness (distance in the X-axis direction).

[0188] Although the present invention has been described with reference to preferred embodiments as described above, it is not limited to the above embodiments, and various changes and modifications may be made by a person having ordinary skill in the art to which the invention pertains within a scope that does not depart from the spirit of the present invention.

[0189] The present invention provides a wall-mounted mounting structure for an energy storage device that is easy to install and can stably support the energy storage device.
