[0052] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as commonly understood by those skilled in the art.

[0053] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0054] Combine Figure 1 and Figure 2 As shown, this embodiment provides an energy storage module, which includes: a box body 1, an installation component 2 and a battery module 3, and the installation component 2 and the battery module 3 are respectively located in the box body 1.

[0055] The mounting assembly 2 includes a first limiting plate 21 and a second limiting plate 22 .

[0056] The first limiting plate 21 and the second limiting plate 22 are respectively in contact with two opposite side surfaces of the battery module 3, and at least one of the first limiting plate 21 and the second limiting plate 22 is movably connected to the first inner wall 101 of the box body 1 so that the distance between the first limiting plate 21 and the second limiting plate 22 is adjustable.

[0057] In the energy storage module of this embodiment, the battery module 3 is fixed in the box body 1 by the installation component 2, and the first limit plate 21 and the second limit plate 22 of the installation component 2 are respectively abutted on the two opposite sides of the battery module 3, and at least one of the two limit plates is movably connected to the first inner wall 101 of the box body 1, so that the spacing between the two limit plates can be adjusted. When there is a gap between the battery module 3 and the two limit plates, the position of the limit plates can be adjusted so that the spacing between the two limit plates is exactly the same as the size of the corresponding direction of the battery module 3, so that the two limit plates can be tightly fitted on the sides of the battery module 3, respectively, to achieve complete limiting constraint of the battery module 3.

[0058] In some possible implementations, the box body 1 may be in the shape of a cuboid.

[0059] In some possible implementations, the battery module 3 may be in the shape of a cuboid, and the first limiting plate 21 and the second limiting plate 22 may respectively abut against two side surfaces of the battery module 3 along the length direction A.

[0060] Exemplarily, the battery module 3 includes a plurality of battery cells, each of which has a tab located at a top end of the battery cell in a height direction B of the battery module 3 .

[0061] In some other possible implementations, the first limiting plate 21 and the second limiting plate 22 are sheet metal structures, which have simple structures, low production and processing costs, and are easy to install.

[0062] Combine Figure 2 As shown, in some embodiments, the first limiting plate 21 is movably connected to the first inner wall 101 .

[0063] One of the first limiting plate 21 and the first inner wall 101 is provided with a fixing groove 2121 , and the other one is provided with a fixing column 11 .

[0064] The fixing post 11 is movably connected to the fixing slot 2121 . When the relative positions of the fixing post 11 and the fixing slot 2121 are adjusted, the distance between the first limiting plate 21 and the second limiting plate 22 changes.

[0065] Through the above arrangement, the movable connection between the first limit plate 21 and the first inner wall 101 is achieved by utilizing the cooperation between the fixing groove 2121 and the fixing column 11. The specific position of the fixing column 11 in the fixing groove 2121 can be adjusted, and the positions of the fixing column 11 and the fixing groove 2121 can be fixed to each other, thereby realizing the adjustment of the relative position of the first limit plate 21 and the first inner wall 101, and further realizing the adjustment of the spacing between the first limit plate 21 and the second limit plate 22.

[0066] In some possible implementations, the mounting assembly 2 further includes a compression nut, which can be threadedly connected to the fixing column 11. When the compression nut is loosened, the fixing groove 2121 and the fixing column 11 are in a movable state, so that the position can be adjusted. When the position adjustment is completed, the compression nut is tightened to lock the relative position of the fixing groove 2121 and the fixing column 11.

[0067] Exemplarily, the first limiting plate 21 is provided with a fixing groove 2121, and the first inner wall 101 is provided with a fixing column 11. Alternatively, the first limiting plate 21 is provided with a fixing column 11, and the first inner wall 101 is provided with a fixing groove 2121.

[0068] In some possible implementations, the second limiting plate 22 is movably connected to the first inner wall 101 , and a fixing groove 2121 is provided on one of the second limiting plate 22 and the first inner wall 101 , and a fixing column 11 is provided on the other.

[0069] In other possible implementations, the first limiting plate 21 and the second limiting plate 22 are respectively movably connected to the first inner wall 101, and one of the first limiting plate 21 and the first inner wall 101 is provided with a fixing groove 2121, and the other is provided with a fixing column 11, and one of the second limiting plate 22 and the first inner wall 101 is provided with a fixing groove 2121, and the other is provided with a fixing column 11, so that the first limiting plate 21 and the second limiting plate 22 can adjust their relative positions with the first inner wall 101, and then adjust the distance between the first limiting plate 21 and the second limiting plate 22 to meet the size requirements of battery modules 3 of different sizes.

[0070] In other possible implementations, if the first limiting plate 21 and the second limiting plate 22 respectively abut against the two side surfaces of the battery module 3 along the length direction A, the first limiting plate 21 and / or the second limiting plate 22 are movably connected to the first inner wall 101, so that the spacing between the first limiting plate 21 and the second limiting plate 22 along the length direction A can be adjusted. When the spacing between the first limiting plate 21 and the second limiting plate 22 along the length direction A is equal to the length of the battery module 3, the first limiting plate 21 and the second limiting plate 22 can respectively abut against the two side surfaces of the battery module 3 along the length direction A, thereby realizing reliable limiting constraints of the battery module 3 along the length direction A.

[0071] Exemplarily, the extension direction of the fixing groove 2121 is parallel to the length direction A of the battery module 3, so that when the position of the fixing column 11 in the fixing groove 2121 is adjusted, the first limiting plate 21 or the second limiting plate 22 can be moved along the length direction A, thereby adjusting the distance between the two along the length direction A.

[0072] Combine Figure 2As shown, in some embodiments, there are multiple fixing slots 2121 and fixing posts 11, and the multiple fixing slots 2121 are arranged at intervals, with each fixing slot 2121 corresponding to a fixing post 11. Exemplarily, the multiple fixing slots 2121 are parallel to the length direction A of the battery module 3. In another exemplary embodiment, the multiple fixing slots 2121 and fixing posts 11 are arranged at intervals along the height direction B of the battery module 3.

[0073] Through the above arrangement, when the number of fixing grooves 2121 and fixing columns 11 is multiple and parallel, on the one hand, multiple fixing points can be provided for the first limiting plate 21, and on the other hand, multiple fixing grooves 2121 can be used to form parallel regulations, and the first limiting plate 21 has a better activity effect when adjusting its position along the length direction A.

[0074] Combine Figure 2 As shown, in some embodiments, the first limiting plate 21 includes a first limiting plate body 211 and a first bending section 212 that are fixedly connected. The first limiting plate body 211 abuts against a side surface of the battery module 3 along the length direction A, and the first bending section 212 is parallel to the first inner wall 101.

[0075] A fixing groove 2121 is defined on the first bending section 212 , and the fixing groove 2121 extends along the length direction A.

[0076] A fixing column 11 is provided on the first inner wall 101 .

[0077] In this embodiment, the first limiting plate body 211 abuts against a side surface of the battery module 3 along the length direction A, and the first bending section 212 fixedly connected to the first limiting plate body 211 is parallel to the first inner wall 101, so that it can be fitted on the first inner wall 101 and connected to the fixed column 11 at the corresponding position using the fixing groove 2121 thereon. The movable connection method between the first limiting plate 21 and the first inner wall 101 is simple and easy to assemble and disassemble, and the position of the first limiting plate 21 can be quickly adjusted, which is highly practical.

[0078] Combine Figure 1 and Figure 2 As shown, in some embodiments, the first bending section 212 is located on a side of the first limiting plate body 211 facing away from the battery module 3 .

[0079] Through the above arrangement, the first bending section 212 is on the outside of the first limiting plate 21, so that when the battery module 3 is installed between the first limiting plate 21 and the second limiting plate 22, the relative position of the fixing groove 2121 and the first fixing member can be adjusted on the outside, and the position adjustment operation of the first limiting plate 21 is simple and efficient.

[0080] Combine Figure 1 and Figure 2As shown, in some embodiments, the first limiting plate 21 further includes a second bent section 213. The second bent section 213 is fixedly connected to the top edge of the first limiting plate body 211 and is located on the side of the first limiting plate body 211 facing the battery module 3. The second bent section 213 abuts against the top surface of the battery module 3 along the height direction B.

[0081] Through the above arrangement, the second bending section 213 of the first limiting plate 21 is defined, and the second bending section 213 can abut against the top of the battery module 3, thereby limiting the height direction B of the battery module 3.

[0082] Combine Figure 1 and Figure 4 As shown, in some embodiments, the first limiting plate 21 is movably connected to the first inner wall 101 using the fixing groove 2121, and the second limiting plate 22 is fixedly connected to the first inner wall 101, wherein the fixed connection between the second limiting plate 22 and the first inner wall 101 can be fixed by bolts, fixed by welding, or fixed by other means.

[0083] Combine Figure 1 and Figure 3 As shown, in some embodiments, the second limiting plate 22 includes a second limiting plate body 221 and a third bending section 222 that are fixedly connected.

[0084] The second limiting plate body 221 contacts the other side surface of the battery module 3 along the longitudinal direction A.

[0085] The third bending section 222 is fixedly connected to the top edge of the second limiting plate body 221 and is located on the side of the second limiting plate body 221 facing the battery module 3. The third bending section 222 is in contact with the top surface of the battery module 3 along the height direction B.

[0086] Through the above arrangement, the second limiting plate 22 can use the second limiting plate body 221 to abut against the other side of the battery module 3 along the length direction A, corresponding to the first limiting plate body 211, to achieve limiting constraint of the battery module 3 along the length direction A.

[0087] The third bending section 222 and the second bending section 213 respectively correspond to the two rectangular ends along the length of the top surface of the battery module 3 , thereby realizing position restriction of the battery module 3 along the height direction B.

[0088] Combine Figure 4 As shown, in some embodiments, the mounting assembly 2 further includes a third limiting plate 23 , which is fixedly connected to the interior of the box body 1 and abuts against the bottom surface of the battery module 3 along the height direction B.

[0089] Through the above arrangement, the third limiting plate 23 can provide limiting support along the height direction B for the battery module 3 from the bottom.

[0092] With this arrangement, the battery module 3 can be installed into the box body 1 along the width direction C. The energy storage module is side-mounted as a whole, and the opening 121 of the box body 12 is also arranged on the side. The top and bottom of the box body 1 can remain intact, making it convenient to arrange structures such as handles on the top of the box body 12 and structures such as legs on the bottom of the box body 12. In addition, the top of the box body 12 with the side opening 121 has better pressure-bearing capacity.

[0093] The mounting assembly 2 further includes at least one fourth limiting plate 24, which abuts the side of the battery module 3 facing the case cover 13 and is detachably connected to at least one of the first limiting plate 21 and the second limiting plate 22. The at least one fourth limiting plate 24, disposed on one side of the case cover 13, provides constraint and limitation for the battery module 3 in the width direction C.

[0094] Exemplarily, the number of fourth limiting plates 24 is, for example, one, two, etc. When the number of fourth limiting plates 24 is one, one end of the fourth limiting plate 24 can be detachably connected to the first limiting plate 21 or the second limiting plate 22, and the other end extends to the side of the battery module 3 along the width direction C.

[0095] Alternatively, the fourth limiting plate 24 extends along the length direction A of the battery module 3, with one end connected to the first limiting plate 21 and the other end connected to the second limiting plate 22, and the middle of the fourth limiting plate 24 abuts against the side of the battery module 3 along the width direction C.

[0097] Through the above arrangement, a fourth bending section 214 is set on the side edge of the first limiting plate body 211 facing the box cover 13, forming a connection area parallel to the side of the battery module 3 facing the box cover 13. The connection area can be parallel to the fourth limiting plate 24 to achieve a detachable connection between the fourth limiting plate 24 and the fourth bending section 214.

[0098] Combine Figure 3 and Figure 4 As shown, in some embodiments, when the second limiting plate 22 includes a second limiting plate body 221, the second limiting plate 22 also includes a fifth bending section 223. When the second limiting plate 22 includes the second limiting plate body 221, the fifth bending section 223 is located on the side of the second limiting plate body 221 facing the box cover 13, and the fifth bending section 223 is detachably connected to at least one fourth limiting plate 24.

[0099] Through the above arrangement, a fifth bending section 223 is set on the side edge of the second limiting plate body 221 facing the box cover 13, forming a connection area parallel to the side of the battery module 3 facing the box cover 13. The connection area can be parallel to the fourth limiting plate 24 to achieve a detachable connection between the fourth limiting plate 24 and the fifth bending section 223.

[0100] Combine Figure 1 As shown, in some embodiments, the battery module 3 includes a strapping strap 31 that surrounds the side of the battery module 3; at least one fourth limiting plate 24 is detachably connected to the strapping strap 31 on the side of the battery module 3 facing the box cover 13.

[0101] Through the above arrangement, the strapping belt 31 surrounds the side of the battery module 3, which can restrain the battery module 3. Moreover, the strapping belt 31 passes through the side of the battery module 3 toward the box cover 13 along the length direction A. Therefore, the battery module 3 can be connected to the fourth limiting plate 24 through the detachable connection between the fourth limiting plate 24 and the strapping belt 31, and then the fourth limiting plate 24 can be used to achieve a detachable connection with the first limiting plate 21 or the second limiting plate 22.

[0102] Combine Figure 1 As shown, in some embodiments, the energy storage module further includes at least one functional module 4 , at least one functional module 4 is located in the box 1 , and at least one functional module 4 is located on the side of the first limiting plate 21 facing away from the battery module 3 .

[0103] Through the above arrangement, the functional module 4 is arranged on the side of the first limiting plate 21 facing away from the battery module 3. The first limiting plate 21 is movably connected to the first inner wall 101 by means of the fixing groove 2121 and the fixing column 11. The first limiting plate 21 can be removed, so that the space on the side facing away from the battery module 3 is larger, and the connection operation of the functional module 4 is more convenient.

[0104] In some implementations, the functional module 4 includes but is not limited to a control module, a communication module, an acquisition harness, and the like.
