[0033] The embodiments of the present disclosure are described in detail below. Examples of the embodiments are shown in the accompanying drawings, and in all of the accompanying drawings, the same or similar reference symbols indicate the same or similar components or components having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0034] 1 to 32, an energy storage module 201 according to an embodiment of the present disclosure is described below. The energy storage module 201 can be installed in an energy storage cabinet to supply power to other electrical appliances.

[0035] As shown in FIG. 1 to FIG. 32 , an energy storage module 201 according to an embodiment of the present disclosure includes an energy storage unit 220, a support beam 219, a first side plate 211, and a second side plate 212. The energy storage unit 220 includes a plurality of cells 208, which are arranged in order along the thickness direction of the cells 208. When the energy storage unit 220 is placed in the direction shown in FIG. 7 , the thickness direction of the cells 208 points to the left-right direction shown in FIG. 7 . The energy storage unit 220 is arranged between the first side plate 211 and the second side plate 212. As shown in FIG. 2 and FIG. 4 , the support beam 219 extends along the thickness direction of the cells 208, and the support beam 219 is connected between the first side plate 211 and the second side plate 212, so that the first side plate 211 and the second side plate 212 can sandwich the energy storage unit 220. The support beam 219 is provided on at least one side of the energy storage unit 220 in the width direction of the cell 208. When the energy storage unit 220 is placed in the direction shown in Fig. 2, the width direction of the cell 208 is the vertical direction of the energy storage module 201 in Fig. 2. The support beam 219 can be provided on the upper side of the energy storage unit 220, the support beam 219 can also be provided on the lower side of the energy storage unit 220, or the support beam 219 can be provided on both the upper side and the lower side of the energy storage unit 220. For example, the support beam 219 is provided on both the upper side and the lower side of the energy storage unit 220.

[0036] As shown in FIG. 4, when the energy storage module 201 is placed in the direction shown in FIG. 4, the first side plate 211 and the second side plate 212 are respectively disposed on the left and right sides of the energy storage unit 220. The present disclosure is described by taking an example in which the first side plate 211 is disposed on the left side of the energy storage unit 220, and the second side plate 212 is disposed on the right side of the energy storage unit 220. The first side plate 211 and the second side plate 212 are connected by a connecting beam, and the energy storage unit 220 is disposed between the first side plate 211 and the second side plate 212, so that after the connecting beam is assembled with the first side plate 211 and the second side plate 212, the first side plate 211 and the second side plate 212 can clamp the energy storage unit 220, and the energy storage unit 220 can be fixed in the energy storage module 201. There is no need to install brackets for fixing the cells 208 inside the energy storage module 201, so the space for arranging the cells 208 in the energy storage module 201 is increased, and more cells 208 can be arranged in the energy storage module 201, thereby improving the energy density of the energy storage module 201. When the energy storage module 201 has the same energy density, the energy storage module 201 of the present disclosure has a smaller volume. Furthermore, by providing the support beams 219 on both the lower and upper sides of the energy storage unit 220, the support beams 219 on the lower side of the energy storage unit 220 can support the energy storage unit 220, so that the energy storage unit 220 is firmly sandwiched between the first side plate 211 and the second side plate 212. At the same time, by clamping the energy storage unit 220 using the support beam 219, the first side plate 211, and the second side plate 212, the structure of the energy storage module 201 can be simplified, the assembly efficiency of the energy storage module 201 can be improved, and the production efficiency of the energy storage module 201 can be thus improved.

[0037] Therefore, the energy storage unit 220 can be clamped by the cooperation of the energy storage unit 220, the first side plate 211, the second side plate 212, and the support beam 219, which simplifies the structure of the energy storage module 201 and improves the assembly efficiency of the energy storage module 201. In addition, there is no need to install brackets to fix the cells 208 inside the energy storage module 201. More cells 208 can be arranged in the energy storage module 201, which improves the energy density of the energy storage module 201. When the energy storage module 201 has the same energy density, the volume of the energy storage module 201 is smaller.

[0038] In some embodiments of the present disclosure, as shown in Figures 1 and 3, the energy storage module 201 may also include a top cover 213 and a bottom cover 214. In the width direction of the cell 208, the top cover 213 and the bottom cover 214 are located on two sides of the energy storage unit 220, respectively. When the energy storage module 201 is placed in the direction shown in Figure 1, in the up-down direction shown in Figure 1, the top cover 213 is disposed on the upper side of the energy storage unit 220, the bottom cover 214 is disposed on the lower side of the energy storage unit 220, and both the top cover 213 and the bottom cover 214 are connected to the first side plate 211 and the second side plate 212. Furthermore, both the top cover 213 and the bottom cover 214 are connected between the first side panel 211 and the second side panel 212, or both the first side panel 211 and the second side panel 212 are connected between the top cover 213 and the bottom cover 214, for example, both the top cover 213 and the bottom cover 214 are connected between the first side panel 211 and the second side panel 212. The second air duct 216 is formed between a surface of the energy storage unit 220 close to the top cover 213 and the top cover 213 and / or between a surface of the energy storage unit 220 close to the bottom cover 214 and the bottom cover 214 due to the separating effect of the support beams 219. That is, the second air duct 216 can be formed between a surface of the energy storage unit 220 close to the top cover 213 and the top cover 213 due to the separating effect of the support beam 219, or the second air duct 216 can be formed between a surface of the energy storage unit 220 close to the bottom cover 214 and the bottom cover 214 due to the separating effect of the support beam 219, and the second air duct 216 can also be formed between a surface of the energy storage unit 220 close to the top cover 213 and the top cover 213, and between a surface of the energy storage unit 220 close to the bottom cover 214 and the bottom cover 214. For example, the second air duct 216 is formed between a surface of the energy storage unit 220 close to the top cover 213 and the top cover 213, and between a surface of the energy storage unit 220 close to the bottom cover 214 and the bottom cover 214.

[0039] Specifically, the support beams 219 are provided between a surface of the energy storage unit 220 close to the top cover 213 and the top cover 213, and between a surface of the energy storage unit 220 close to the bottom cover 214 and the bottom cover 214. The support beams 219 between the energy storage unit 220 and the top cover 213 separate the energy storage unit 220 and the top cover 213 to form a second air duct 216 between the energy storage unit 220 and the top cover 213, and the support beams 219 between the energy storage unit 220 and the bottom cover 214 separate the energy storage unit 220 and the bottom cover 214 to form a second air duct 216 between the energy storage unit 220 and the bottom cover 214. The air outside the energy storage module 201 can flow into the second air duct 216, and after flowing into the second air duct 216, the air can exchange heat with the energy storage unit 220, and then the air will flow out of the energy storage module 201, thereby removing the heat of the cell 208, achieving a cooling effect, and improving the heat dissipation efficiency of the cell 208. Furthermore, by providing the second air duct 216 between the energy storage unit 220 and the top cover 213 and between the energy storage unit 220 and the bottom cover 214, the temperature difference between the two sides of a single cell 208 can be controlled within 4 degrees, so that the temperature difference between different regions of the cell 208 can be more balanced.

[0040] In some embodiments of the present disclosure, as shown in Figures 2, 4, and 5, in order to divide the second air duct 216 into a plurality of sub-air ducts 217, the support beam 219 is in contact with a surface of the energy storage unit 220 close to the top cover 213 and the top cover 213, and / or the support beam 219 is in contact with a surface of the energy storage unit 220 close to the bottom cover 214 and the bottom cover 214, and the support beam 219 has an air passage 218 connecting two adjacent sub-air ducts 217. Furthermore, when the energy storage module 201 is placed in the orientation shown in Figure 1, the support beam 219 located between the energy storage unit 220 and the top cover 213 is in contact with both the upper surface of the energy storage unit 220 and the top cover 213, and the support beam 219 located between the energy storage unit 220 and the bottom cover 214 is in contact with both the lower surface of the energy storage unit 220 and the bottom cover 214. The support beams 219 located between the energy storage unit 220 and the top cover 213 can divide the second air duct 216 into a plurality of sub-air ducts 217, and the support beams 219 located between the energy storage unit 220 and the bottom cover 214 can divide the second air duct 216 into a plurality of sub-air ducts 217. The plurality of sub-air ducts 217 located between the energy storage unit 220 and the top cover 213 are sequentially arranged in the length direction of the cell 208, and the plurality of sub-air ducts 217 located between the energy storage unit 220 and the bottom cover 214 are sequentially arranged in the length direction of the cell 208.

[0041] After the gas outside the energy storage module 201 flows into the sub-air duct 217, the gas can flow into the adjacent sub-air duct 217 through the air passage 218. In the process of the gas flow, the air exchanges heat with the cells 208 and can remove the heat of the cells 208, and finally the gas flows out of the energy storage module 201. In addition, by bringing the support beam 219 into contact with the energy storage unit 220, the support beam 219 located below the energy storage unit 220 can support the energy storage unit 220. Meanwhile, the support beam 219 located below the energy storage unit 220 and the support beam 219 located above the energy storage unit 220 sandwich the energy storage unit 220, so that the energy storage unit 220 is firmly assembled in the energy storage module 201.

[0042] 2 and 4, a plurality of support beams 219 may be provided between the energy storage unit 220 and the top cover 213, and the plurality of support beams 219 between the energy storage unit 220 and the top cover 213 are spaced apart in the length direction of the cell 208 (i.e., the front-to-back direction in FIG. 4). At the same time, a plurality of support beams 219 may be provided between the energy storage unit 220 and the bottom cover 214, and the plurality of support beams 219 between the energy storage unit 220 and the bottom cover 214 are spaced apart in the length direction of the cell 208. By simultaneously clamping the energy storage unit 220 with multiple support beams 219 and by clamping the energy storage unit 220 with the first side plate 211 and the second side plate 212, the energy storage unit 220 can be assembled more securely within the energy storage module 201, and the first side plate 211 and the second side plate 212 can also clamp the energy storage unit 220 securely.

[0043] In some embodiments of the present disclosure, as shown in Fig. 4, the support beam 219 spans all the cells 208 along the thickness direction of the cells 208. As shown in Fig. 4, the leftmost end of the support beam 219 is connected to the first side plate 211, and the rightmost end of the support beam 219 is connected to the second side plate 212. The support beam 219 spans all the cells 208 along the thickness direction of the cells 208 and then connects to the first side plate 211 and the second side plate 212, so that the first side plate 211 and the second side plate 212 can securely sandwich the energy storage unit 220.

[0044] In some embodiments of the present disclosure, as shown in FIG. 5 , the inner surface of the first side plate 211 close to the energy storage unit 220 and / or the inner surface of the second side plate 212 close to the energy storage unit 220 may be provided with a limiting boss 221 protruding toward the energy storage unit 220. It may be understood that the limiting boss 221 can be provided on the inner surface of the first side plate 211 close to the energy storage unit 220, and the limiting boss 221 can also be provided on the inner surface of the second side plate 212 close to the energy storage unit 220. The limiting boss 221 can also be provided on the inner surface of the first side plate 211 close to the energy storage unit 220 and the inner surface of the second side plate 212 close to the energy storage unit 220. After the support beam 219, the first side plate 211, and the second side plate 212 are assembled, the limiting boss 221 can press the energy storage unit 220, so that the energy storage unit 220 is fixed in the energy storage module 201.

[0045] In addition, the support beam 219 is overlapped on the limiting boss 221. Specifically, as shown in FIG. 5, the two ends of the support beam 219 located between the energy storage unit 220 and the top cover 213 are overlapped on the upper surface of the limiting boss 221 of the first side plate 211 and the upper surface of the limiting boss 221 of the second side plate 212, respectively. The limiting boss 221 supports the support beam 219 between the energy storage unit 220 and the top cover 213, so that the support beam 219 can be reliably assembled with the first side plate 211 and the second side plate 212. The two ends of the support beam 219 between the energy storage unit 220 and the bottom cover 214 are overlapped on the lower surface of the limiting boss 221 of the first side plate 211 and the lower surface of the limiting boss 221 of the second side plate 212, respectively. The limiting boss 221 supports the support beam 219 between the energy storage unit 220 and the bottom cover 214 , thereby preventing the support beam 219 between the energy storage unit 220 and the bottom cover 214 from excessively compressing the cell 208 .

[0046] In some embodiments of the present disclosure, as shown in Fig. 5, a third air duct 222 is formed in the restrictive boss 221, and the third air duct 222 extends in the length direction of the cell 208. Since the restrictive boss 221 is in contact with the energy storage unit 220, after the gas flows into the third air duct 222, the gas can exchange heat with the energy storage unit 220. When the gas flows along the third air duct 222, the gas can continuously remove the heat of the energy storage unit 220, thereby achieving the effect of cooling the energy storage unit 220.

[0047] In some embodiments of the present disclosure, as shown in FIG. 5, both the first side plate 211 and the second side plate 212 are provided with mounting holes 223 for assembling the support beam 219, the axis of the mounting hole 223 extends in the thickness direction of the cell 208, the mounting hole 223 on the first side plate 211 penetrates the first side plate 211 in the thickness direction of the first side plate 211, the mounting hole 223 on the second side plate 212 penetrates the second side plate 212 in the thickness direction of the second side plate 212, and the fasteners 224 penetrate the mounting holes 223 and engage with the support beam 219, so that the first side plate 211 and the second side plate 212 can clamp the energy storage unit 220. There are a plurality of fasteners 224 and mounting holes 223, and the plurality of mounting holes 223 and the plurality of fasteners 224 are arranged one by one. The fasteners 224 may be bolts or screws. The fasteners 224 pass through corresponding mounting holes 223 from the outside of the first side panel 211 and the second side panel 212 and are threadedly connected to the support beam 219, thereby fixing the first side panel 211 and the second side panel 212 together, and the first side panel 211 and the second side panel 212 then clamp the energy storage unit 220.

[0048] In some embodiments of the present disclosure, as shown in FIG. 7 and FIG. 8, the energy storage module 201 may also include a heat sink 209, the heat sink 209 is provided between at least two adjacent cells 208 of the plurality of cells 208, the heat sink 209 is in contact with the adjacent cells 208, and the heat sink 209 defines a first air duct 210 extending along the length direction of the cells 208. When the energy storage module 201 is placed in the orientation shown in FIG. 7, the length direction of the cells 208 points to the front-back direction shown in FIG. 7. This arrangement allows the contact surface between the heat sink 209 and the cells 208 to be a large surface of the cells 208, which can improve the heat dissipation effect of the heat sink 209 on the cells 208. Furthermore, gas (such as cold air) can flow into the first air duct 210 after entering the energy storage module 201. When the cool air flows along the first air duct 210, the cool air exchanges heat with the cells 208, removing heat from the cells 208, thereby achieving a cooling effect for the cells 208. After the air in the first air duct 210 exits the first air duct 210, the air can flow out of the energy storage module 201, thereby releasing heat from the energy storage module 201.

[0049] In some embodiments of the present disclosure, as shown in Figures 5, 7, and 8, the heat sink 209 can define multiple first air ducts 210, which are arranged sequentially along the width direction of the cell 208. When the energy storage module 201 is placed in the direction shown in Figure 7, the width direction of the cell 208 points to the up-down direction shown in Figure 7. This setting allows the gas to flow smoothly in the different first air ducts 210 and avoids the formation of vortexes in the heat sink 209, thereby ensuring the gas flow velocity and facilitating the gas to flow out of the heat sink 209, thereby quickly removing the heat of the cell 208 and also avoiding the noise generated by the gas in the heat sink 209.

[0050] In some embodiments of the present disclosure, as shown in FIG. 7 and FIG. 8, a plurality of cells 208 may form a plurality of cells, each of which includes at least one cell 208. Moreover, as shown in FIG. 7, every two cells 208 form one cell, and two cells 208 located at the end form one cell respectively. A heat sink 209 is provided between two adjacent cells, ensuring that each cell 208 is in contact with at least one heat sink 209, so that each cell 208 has at least one heat sink 209 to dissipate its heat, and the heat sink can also be coupled to the side of the cell 208 with a larger area, thereby enlarging the heat dissipation area of ​​the cell 208 and reducing the temperature difference of various regions of the cell 208. At the same time, due to the arrangement of the multiple cells 208 and the heat sink 209, the heat sink 209 can provide support for the cells 208, thereby improving the structural stability and safety of the energy storage module 201.

[0051] In some embodiments of the present disclosure, as shown in Figures 4 and 12, the energy storage module 201 may further include a driving fan 2061. The driving fan 2061 is located at one end of the energy storage unit 220 in the length direction of the cell 208, the driving fan 2061 is spaced apart from the energy storage unit 220, and the driving fan 2061 is used to drive the gas to flow along the first air duct 210 in the first air duct 210. Furthermore, as shown in Figure 4, when the energy storage module 201 is placed in the direction shown in Figure 4, the driving fan 2061 is located at the front end of the energy storage unit 220, and the selection of the driving fan 2061 may choose different models of fans based on specific heat dissipation requirements. When the driving fan 2061 is working, the blades of the driving fan 2061 rotate, and under the driving of the driving fan 2061, the gas in the first air duct 210 flows along the first air duct 210 toward the driving fan 2061, the heat generated by the cells 208 is removed by the gas flow, and the gas carried out by the driving fan 2061 is finally discharged to the outside of the energy storage module 201. By providing the driving fan 2061, the gas flow velocity in the first air duct 210 can be increased, and the heat of the cells 208 can be removed more quickly, thereby improving the heat exchange efficiency of the heat sink 209.

[0052] In some embodiments of the present disclosure, as shown in FIG. 4 and FIG. 6, multiple driving fans 2061 can be installed, and the multiple driving fans 2061 are sequentially spaced apart along the thickness direction of the cells 208. It should be noted that the number of driving fans 2061 is positively correlated with the number of cells 208 in the energy storage module 201, that is, the more cells 208 installed in the energy storage module 201, the more driving fans 2061 are installed, and the fewer cells 208 installed in the energy storage module 201, the fewer driving fans 2061 are installed. The present disclosure takes an example of installing two driving fans 2061 in the energy storage module 201 for illustration. By installing multiple driving fans 2061, the covering area of ​​the driving fans 2061 can be enlarged, thus ensuring the improvement of the gas flow rate of the first air duct 210 of each heat sink 209 in the energy storage module 201, thereby further improving the heat dissipation efficiency of the energy storage module 201.

[0053] In some embodiments of the present disclosure, as shown in FIG. 6, along the thickness direction of the cell 208, the interval distance between any two adjacent driving fans 2061 is A, which satisfies the relationship 90 mm≦A≦100 mm. For example, the interval distance between two adjacent driving fans 2061 is 98 mm. By setting the interval distance between two adjacent driving fans 2061 to A in the thickness direction of the cell 208, i.e., in the left-right direction of FIG. 6, it can be ensured that the driving fan 2061 can drive the gas flow in the first air duct 210 located between the two driving fans 2061, and the heat of the cell 208 can be removed more quickly, thereby ensuring the heat exchange efficiency of the heat sink 209.

[0054] In some embodiments of the present disclosure, as shown in FIG. 6, along the thickness direction of the cell 208, the spacing distance between the center of one of any two adjacent driving fans 2061 and the center of the other driving fan 2061 is B, which satisfies the relationship 180 mm≦B≦200 mm. For example, the spacing distance between the center of one of the two adjacent driving fans 2061 and the center of the other driving fan 2061 is 190 mm. This installation can further ensure that the driving fan 2061 can drive the gas flow in the first air duct 210 located between the two driving fans 2061, thereby removing the heat of the cell 208 more quickly, and further ensure the heat exchange efficiency of the heat sink 209.

[0055] In some embodiments of the present disclosure, as shown in FIG. 6, in the length direction of the cell 208, the clearance distance between the driving fan 2061 and the cell 208 is C, which satisfies the relationship 40 mm≦C≦50 mm. For example, the clearance distance between the driving fan 2061 and the cell 208 is 45.6 mm. Furthermore, in the length direction of the cell 208, the clearance distance between the driving fan 2061 and the heat sink 209 is also C. This setting can further ensure that the driving fan 2061 can drive the gas flow in the first air duct 210 located between the two driving fans 2061, and can remove the heat of the cell 208 more quickly, thereby further ensuring the heat exchange efficiency of the heat sink 209, so that the clearance dimension between the driving fan 2061 and the cell 208 and the clearance dimension between the driving fan 2061 and the heat sink 209 are appropriate.

[0056] In some embodiments of the present disclosure, as shown in FIG. 6, in the thickness direction of the cell 208, the spacing distance between the outermost surface of the heat sink 209 away from the driving fan 2061 and the adjacent driving fan 2061 is D, which satisfies the relationship 60 mm≦D≦70 mm. For example, the spacing distance between the outermost surface of the heat sink 209 away from the driving fan 2061 and the adjacent driving fan 2061 is 65.2 mm. Such a setting can ensure that the gas in each first air duct 210 flows driven by the driving fan 2061, which can improve the temperature consistency of various regions of the energy storage module 201, thereby ensuring the uniform heat dissipation of the energy storage module 201.

[0057] It should be noted that the larger the size of the driving fan 2061, the faster the air flow speed in the first air duct 210. In the width direction of the cell 208, the size of the driving fan 2061 is equal to or greater than the width dimension of the cell 208. At this time, the size of the driving fan 2061 in the width direction of the cell 208 reaches 100% of the coverage of the cell 208, and the working area of ​​the driving fan 2061 is circular, so that the maximum air flow is realized in the first air duct 210 to ensure the heat dissipation effect of the energy storage module 201. Furthermore, in the width direction of the energy storage module 201, the set size of the driving fan 2061 occupies 40% to 50% of the width dimension of the energy storage module 201, for example, the set size of the driving fan 2061 occupies 44.62% of the width dimension of the energy storage module 201.

[0058] In some embodiments of the present disclosure, in the thickness direction of the cell 208, the area of ​​the side (i.e., large surface) of the cell 208 is S1, and the contact area between the heat sink 209 and the adjacent cell 208 is S2, which satisfies the relationship 0.90≦S2 / S1≦1, for example, S2 / S1 is 0.97. This setting can ensure the contact area between the heat sink 209 and the adjacent cell 208, and can improve the heat exchange efficiency between the heat sink 209 and the cell 208.

[0059] 4 and 12 , the energy storage module 201 may also include a heat dissipating end plate 206, on which the driving fan 2061 is mounted, and which is fixedly connected to the first side plate 211 and / or the second side plate 212. It may also be understood that the heat dissipating end plate 206 can be connected to the first side plate 211, or the heat dissipating end plate 206 can be connected to the second side plate 212, or the heat dissipating end plate 206 can be fixedly connected to both the first side plate 211 and the second side plate 212. 4, the heat-dissipating end plate 206 is installed at the front end of the first side plate 211 and the second side plate 212, the heat-dissipating end plate 206 is connected to both the first side plate 211 and the second side plate 212, and the heat-dissipating end plate 206 can be installed on the first side plate 211 and the second side plate 212 by bolts. Also, the heat-dissipating end plate 206 is spaced apart from the energy storage unit 220. By installing the driving fan 2061 on the heat-dissipating end plate 206, the gas in the first air duct 210 can move toward the front of the energy storage module 201 along the first air duct 210, and the driving fan 2061 can be reliably disposed in the energy storage module 201.

[0060] In addition, as shown in FIG. 1, FIG. 19 to FIG. 21, the energy storage module 201 may also include a connection piece 2083 and a busbar mounting rack 2084. In the length direction of the cell 208, a positive pole and a negative pole are provided at two ends of the cell 208, respectively. The connection piece 2083 is connected between the positive pole and the negative pole of two adjacent cells 208 to realize the electrical connection of the two adjacent cells 208. The busbar mounting rack 2084 is disposed between the heat dissipation end plate 206 and the energy storage unit 220. The connection piece 2083 is installed on the busbar mounting rack 2084. The busbar mounting rack 2084 can be fixedly attached to the first side plate 211 and the second side plate 212. For example, the busbar mounting rack 2084 can be attached to the first side plate 211 and the second side plate 212 by bolts, or the busbar mounting rack 2084 can be clamped on the first side plate 211 and the second side plate 212. The specific assembly format is not particularly limited. The heat dissipation end plate 206 is removably attached to the busbar mounting rack 2084, so that the heat dissipation end plate 206 is indirectly attached to the first side plate 211 and the second side plate 212.

[0061] In some embodiments of the present disclosure, as shown in FIG. 1 and FIG. 4, the energy storage module 201 may further include a fixed plate 2065, which is installed on the first side plate 211 and / or the second side plate 212, i.e., the fixed plate 2065 can be installed on the first side plate 211, the fixed plate 2065 can also be installed on the second side plate 212, and the fixed plate 2065 can also be installed on the first side plate 211 and the second side plate 212 at the same time. Furthermore, the portion of the fixed plate 2065 connected to the side plate is configured as a flat plate structure. As shown in FIG. 2 and FIG. 4, the fixed plate 2065 can be provided with a handle 2066. Furthermore, the handle 2066 is provided on the end of the fixed plate 2065 away from the side plate, and the portion of the fixed plate 2065 connected to the handle 2066 is configured as a flat plate structure. When the energy storage module 201 needs to be removed and put away, an attendant can lift the energy storage module 201 by grasping the handle 2066, thereby facilitating transportation of the energy storage module 201. In some embodiments of the present disclosure, the heat dissipating end plate 206 can be fixedly connected to the fixed plate 2065, and the heat dissipating end plate 206 can be attached to the fixed plate 2065 using bolts.

[0062] 1, the energy storage module 201 may also include a fixing bracket 2067, which is installed on the first side plate 211 and / or the second side plate 212, for example, the first side plate 211 and the second side plate 212 are both provided with the fixing bracket 2067, the fixing bracket 2067 is located between the fixing plate 2065 and the heat dissipating end plate 206, the fixing bracket 2067 is located inside the fixing plate 2065, and the fixing bracket 2067 is used to limit the position of the heat dissipating end plate 206. As shown in FIG. 1 and FIG. 4, the fixing bracket 2067 is provided on the front end of the first side plate 211 and the front end of the second side plate 212. In the front-rear direction of the energy storage module 201, the fixing bracket 2067 is provided between the heat dissipation end plate 206 and the side plate (i.e., the first side plate 211 and the second side plate 212). By providing the fixing bracket 2067 between the heat dissipation end plate 206 and the side plate, the heat dissipation end plate 206 can be spaced apart from the energy storage unit 220, and an installation space can be provided for arranging components such as the connection piece 2083, that is, an installation space can be provided for arranging the bus bar mounting rack 2084. In addition, due to the restrictive cooperation between the fixing bracket 2067 and the heat dissipation end plate 206, the fixing bracket 2067 can limit the movement of the heat dissipation end plate 206 in the width direction of the energy storage module 201, and the heat dissipation end plate 206 and the bus bar mounting rack 2084 can be reliably assembled. In addition, the fixing bracket 2067 is removably connected to the fixing plate 2065, for example, the fixing bracket 2067 and the fixing plate 2065 are securely fixed by bolts or screws. The heat dissipating end plate 206 can also be attached to the fixing bracket 2067 by bolts or screws.

[0063] 14, an insertion post 2085 is provided in the fixing bracket 2067, and an insertion hole 2086 is provided in both the first side plate 211 and the second side plate 212. When the fixing bracket 2067 is assembled with the first side plate 211, the insertion post 2085 is inserted into the insertion hole 2086 of the first side plate 211, and the fixing bracket 2067 and the first side plate 211 are fixed together with a bolt. When the fixing bracket 2067 is assembled with the second side plate 212, the insertion post 2085 is inserted into the insertion hole 2086 of the second side plate 212, and the fixing bracket 2067 and the second side plate 212 are fixed together with a bolt. This setting allows the fixing bracket 2067 to be firmly installed on the first side plate 211 and the second side plate 212, which is convenient for disassembly and assembly of the fixing bracket 2067.

[0064] In some embodiments of the present disclosure, as shown in Figures 4 and 13, the heat dissipating end plate 206 is provided with a positive electrode connection terminal 2029 and a negative electrode connection terminal 2030, the positive electrode connection terminal 2029 is connected to all positive output terminals of the energy storage unit 220, and the negative electrode connection terminal 2030 is connected to all negative output terminals of the energy storage unit 220. Furthermore, in the thickness direction of the cell 208, the positive electrode connection terminal 2029 and the negative electrode connection terminal 2030 are disposed near the same side of the heat dissipating end plate 206, for example, as shown in Figure 4, the positive electrode connection terminal 2029 and the negative electrode connection terminal 2030 are disposed near the left side of the heat dissipating end plate 206. When the energy storage modules 201 are stacked in the energy storage cabinet, the positive electrode connection terminal 2029 and the negative electrode connection terminal 2030 are arranged on the same side of the heat dissipation end plate 206, so that in two adjacent energy storage modules 201, the positive electrode connection terminal 2029 of one energy storage module 201 and the negative electrode connection terminal 2030 of the other energy storage module 201 can be connected, and the length of the conductive bar 10 can be shortened. The conductive bar 10 is connected between the positive electrode connection terminal 2029 and the negative electrode connection terminal 2030. Furthermore, the conductive bar 10 is plug-connected to both the positive electrode connection terminal 2029 and the negative electrode connection terminal 2030.

[0065] In some embodiments of the present disclosure, as shown in FIG. 4 and FIG. 13, the heat dissipating end plate 206 can define a mounting groove 2063, and the positive electrode connecting terminal 2029 and the negative electrode connecting terminal 2030 are both disposed in the mounting groove 2063. Furthermore, the mounting groove 2063 is recessed from the outer surface of the heat dissipating end plate 206 toward the inside of the heat dissipating end plate 206. By disposing the positive electrode connecting terminal 2029 and the negative electrode connecting terminal 2030 in the mounting groove 2063, the positive electrode connecting terminal 2029 and the negative electrode connecting terminal 2030 can be hidden in the mounting groove 2063, thereby preventing the positive electrode connecting terminal 2029 and the negative electrode connecting terminal 2030 from protruding from the outer surface of the heat dissipating end plate 206 and interfering with other components.

[0066] 4 and 13, the heat dissipating end plate 206 further defines a foolproof slot 203, the foolproof slot being in communication with the mounting groove 2063, and the foolproof slot 203 being used for wiring (e.g., conductive bar 10). Further, the foolproof slot 203 includes a first slot segment 20641, a second slot segment 20642, and a third slot segment 20643. The first slot segment 20641 and the second slot segment 20642 both extend in the height direction of the energy storage module 201, the second slot segment 20642 extends in the width direction of the energy storage module 201, one end of the second slot segment 20642 is connected to the first slot segment 20641, the other end of the second slot segment 20642 is connected to the third slot segment 20643, the third slot segment 20643 is connected to the mounting groove 2063, and the shape of the conductive bar 10 is adapted to match the shape of the foolproof slot 203. As shown in FIG. 13, the positive electrode connection terminal 2029 may be located to the left of the negative electrode connection terminal 2030. When multiple energy storage modules 201 are stacked in order, the conductive bar 10 is connected between two adjacent energy storage modules 201. The lower end of the conductive bar 10 is plugged into the positive electrode connection terminal 2029 of the energy storage module 201 located below, and the upper end of the conductive bar 10 is plugged into the negative electrode connection terminal 2030 of the energy storage module 201 located above, thereby realizing an electrical connection between two adjacent energy storage modules 201. In addition, by placing the conductive bar 10 in the foolproof slot 203, the foolproof slot 203 can guide the conductive bar 10 and prevent the conductive bar 10 from being installed incorrectly (for example, the upper end of the conductive bar 10 and the negative electrode connection terminal 2030 of the energy storage module 201 located above, and the lower end of the conductive bar 10 and the negative electrode connection terminal 2030 of the energy storage module 201 located below).At the same time, hiding the conductive bar 10 in the foolproof slot 203 can avoid the conductive bar 10 from interfering with other components, thereby ensuring the reliability of the assembly between the conductive bar 10 and the positive electrode connecting terminal 2029 and the negative electrode connecting terminal 2030.

[0067] 4, when the energy storage module 201 is placed in the orientation shown in FIG. 4, the wiring slot 2064 is disposed on the upper side of the mounting groove 2063, and the foolproof slot 203 is disposed on the lower side of the mounting groove 2063. The wiring slot 2064 is disposed corresponding to the positive connecting terminal 2029, and the foolproof slot 203 is disposed corresponding to the negative connecting terminal 2030. When multiple energy storage modules 201 are stacked in order, the conductive bar 10 is connected between two adjacent energy storage modules 201, the lower end of the conductive bar 10 is plugged into and connected to the positive electrode connection terminal 2029 of the lower energy storage module 201 and is located in the wiring slot 2064 of the energy storage module 201, and the upper end of the conductive bar 10 is plugged into and connected to the negative electrode connection terminal 2030 of the upper energy storage module 201 and is located in the foolproof slot 203 of the energy storage module 201, thereby connecting the two energy storage modules 201 in series. The wiring slot 2064 is used to avoid the conductive bar 10. The conductive bar 10 is hidden in the wiring slot 2064 to avoid interference between the conductive bar 10 and other components. The foolproof slot 203 and the wiring slot 2064 can both limit the position of the conductive bar 10.

[0068] In some embodiments of the present disclosure, the energy storage module 201 may also include a temperature sensing member, which is used to collect the temperature of the energy storage unit 220. It should be noted that the temperature sensing member may be installed as a temperature sensor. Both the driving fan 2061 and the temperature sensing member are suitable for connection to a battery management system of the energy storage module 201. The battery management system is used to control the speed of the driving fan 2061 by receiving the temperature information collected by the temperature sensing member.

[0069] The driving fan 2061 and the temperature detection member can be connected to the battery management system of the energy storage module 201 through a communication harness. The temperature detection member can detect the temperature of the energy storage unit 220 in real time. After the temperature detection member transmits the detected temperature information to the battery management system, the battery management system controls the rotation speed of the driving fan 2061 according to the received temperature information. For example, when the temperature of the energy storage unit 220 is high (e.g., above 35°C), the battery management system controls the driving fan 2061 to increase the rotation speed, preferably to rotate at full speed, thereby effectively cooling the energy storage module 201. When the temperature of the energy storage unit 220 is low (e.g., the temperature reaches 30°C), the battery management system controls the driving fan 2061 to decrease the rotation speed, so that the driving fan 2061 rotates at half speed, thereby effectively cooling the energy storage module 201 as well. This setting can realize the variable speed adjustment of the driving fan 2061 of the energy storage module 201 at different temperatures, and can adjust the driving fan 2061 to a suitable speed to meet the heat dissipation requirements of the energy storage module 201, which helps to save electricity bills and has an important effect on improving heat dissipation efficiency and power utilization rate. In addition, this arrangement maintains the stability of the temperature of the energy storage module 201 during operation, and effectively supports the stable output of the energy storage module 201.

[0070] 22, the energy storage module 201 can also be equipped with an information collector 2062 (BIC), which can be connected between the temperature detection member and the battery management system. The temperature information detected by the temperature detection member is transmitted to the battery management system through the information collector 2062. In addition, the driving fan 2061 is electrically connected to the information collector 2062 through a wiring harness. By obtaining power from the outside using the information collector 2062, the driving fan 2061 is driven to rotate.

[0071] In some embodiments of the present disclosure, as shown in FIG. 1, FIG. 2 and FIG. 32, the energy storage module 201 may further include a ventilation panel 207, where the ventilation panel 207 is disposed on a side of the driving fan 2061 away from the energy storage unit 220, and the ventilation panel 207 is provided with an air outlet hole 20722. As shown in FIG. 1, the ventilation panel 207 and the heat-dissipating end plate 206 are both disposed on the front side of the energy storage unit 220, the heat-dissipating end plate 206 is located between the ventilation panel 207 and the energy storage unit 220, and the ventilation panel 207 is installed on the heat-dissipating end plate 206. In addition, the ventilation panel 207 can be installed on the heat-dissipating end plate 206 by magnetic attraction, and the ventilation panel 207 can also be installed on the heat-dissipating end plate 206 by bolts. The specific assembly method of the ventilation panel 207 and the heat-dissipating end plate 206 is selected according to the actual situation. When the driving fan 2061 is working, the blades of the driving fan 2061 rotate. Under the driving of the driving fan 2061, the gas in the first air duct 210 flows along the first air duct 210 toward the driving fan 2061, and the heat generated by the cells 208 is removed by the gas flow. The gas carried out by the driving fan 2061 is finally discharged to the outside of the energy storage module 201 through the air outlet holes 20722 on the ventilation panel 207, thereby realizing the function of dissipating hot air. In addition, the ventilation panel 207 can also shield the driving fan 2061 to prevent the driving fan 2061 from being exposed to the outside of the energy storage module 201.

[0072] In some embodiments of the present disclosure, as shown in FIG. 1 and FIG. 2, the energy storage module 201 may further include an end plate 2081, which is arranged at the other end of the energy storage unit 220 and spaced apart from the energy storage unit 220, and which is connected to the top cover 213 and / or the bottom cover 214, and which is provided with a first air inlet hole 2082 communicating with the first air duct 210. The end plate 2081 may be directly or indirectly connected to both the top cover 213 and the bottom cover 214, and the end plate 2081 may be directly assembled with the top cover 213 and the bottom cover 214 by bolts. As shown in FIG. 1, a busbar mounting rack 2084 may be provided between the end plate 2081 and the energy storage unit 220. The busbar mounting rack 2084 is directly or indirectly attached to the first side plate 211 and the second side plate 212. The busbar mounting rack 2084 is also provided with a connecting piece 2083. The end plate 2081 may be attached to the top cover 213 and / or the bottom cover 214, thereby realizing an indirect connection between the end plate 2081 and the first side plate 211 and the second side plate 212. In addition, the end plate 2081 is provided with a first air inlet hole 2082 communicating with the first air duct 210, so that the gas can flow into the energy storage module 201 through the first air inlet hole 2082. A part of the gas flowing into the energy storage module 201 flows into the heat sink 209, and another part of the gas flows into the second air duct 216, so that the cells 208 are surrounded by the gas, thereby improving the heat dissipation efficiency of the cells 208.

[0073] In some embodiments of the present disclosure, as shown in Fig. 1, the top cover 213 and / or the bottom cover 214 may be provided with a second air inlet hole 215 connected to the second air duct 216. For example, both the top cover 213 and the bottom cover 214 are provided with a second air inlet hole 215 connected to the second air duct 216. The cool air can flow into the second air duct 216 through the second air inlet hole 215, so that the cells 208 are surrounded by the cool air, thereby further improving the heat dissipation efficiency of the cells 208.

[0074] In some embodiments of the present disclosure, as shown in Fig. 11, the cell 208 is flat and resembles a blade, and the cell 208 may be a new type of lithium iron phosphate battery. The length dimension of the cell 208 is E, where E satisfies the relationship 400mm < E < 1500mm, the width dimension of the cell 208 is F, where F satisfies the relationship 70mm < F < 150mm, and the thickness dimension of the cell 208 is G, where G satisfies the relationship 10mm < G < 25mm. This configuration allows the flat cell 208 to be arranged in the energy storage module 201, and the energy density in the energy storage module 201 can be improved by arranging multiple cells 208 in sequence along the thickness direction of the cell 208.

[0075] The energy storage cabinet according to the embodiment of the present disclosure includes the energy storage module 201 of the above embodiment, and the energy storage module 201 has a simple structure that improves the assembly efficiency of the energy storage module 201, thereby improving the assembly efficiency of the energy storage cabinet. In addition, there is no need to install brackets to fix the cells 208 in the energy storage module 201, and more cells 208 can be arranged in the energy storage module 201, which improves the energy density of the energy storage module 201 and the energy storage cabinet. When the energy storage module 201 has the same energy density, the size of the energy storage module 201 and the energy storage cabinet is reduced.

[0076] In some embodiments of the present disclosure, as shown in Fig. 23 to Fig. 31, two energy storage modules 201 are connected by an electrical connection assembly 100, which is suitable for connecting between the two energy storage modules 201 to realize an electrical connection between the two energy storage modules 201, so as to connect the two energy storage modules 201 in series or in parallel. For illustration, the present disclosure takes an example of connecting the electrical connection assembly 100 between the two energy storage modules 201 in series. The energy storage modules 201 are provided with a connection terminal 202, and two connection terminals 202 can be provided on each energy storage module 201, one of the two connection terminals 202 is configured as a positive connection terminal 2029 of the energy storage module 201, and the other of the two connection terminals 202 is configured as a negative connection terminal 2030 of the energy storage module 201.

[0077] As shown in Fig. 23 to Fig. 31, the electrical connection assembly 100 includes a conductive bar 10 and an insulating cover 20. The conductive bar 10 can be installed as a copper bar. The conductive bar 10 is suitable for plugging and matching with a connection terminal 202 for electrically connecting the conductive bar 10 and the connection terminal 202. The insulating cover 20 is covered on the conductive bar 10. The insulating cover 20 can prevent the conductive bar 10 from popping out of the connection terminal 202. The insulating cover 20 is connected to the connection terminal 202, and the insulating cover 20 is suitable for pressing the conductive bar 10.

[0078] When two energy storage modules 201 need to be connected in series, the conductive bar 10 is inserted and connected to the positive electrode connection terminal 2029 of one of the two energy storage modules 201, and the conductive bar 10 is also inserted and connected to the negative electrode connection terminal 2030 of the other of the two energy storage modules 201, so as to connect the two energy storage modules 201 in series. In the process of inserting the conductive bar 10 into the connection terminal 202, there is no need to use a tool such as a wrench to insert the conductive bar 10 into the connection terminal 202, which can facilitate docking of the conductive bar 10 and the connection terminal 202, improve the assembly efficiency of the conductive bar 10 and the connection terminal 202, and reduce the installation cost of the conductive bar 10 and the connection terminal 202. At the same time, the insulating cover 20 is connected to the connection terminal 202, and the insulating cover 20 presses the conductive bar 10. By pressing the insulating cover 20 against the conductive bar 10, the conductive bar 10 can be securely inserted into the connection terminal 202, which can avoid virtual connection between the conductive bar 10 and the connection terminal 202, prevent arc discharge, improve the safety of the electrical connection assembly 100, and also improve the safety of the energy storage module 201. In addition, the insulating cover 20 is an insulating member, and the insulating cover 20 is covered on the conductive bar 10, which can avoid the conductive bar 10 from being exposed, avoid electric leakage, and improve high voltage safety.

[0079] In some embodiments of the present disclosure, as shown in Figures 26 to 29 and 31, the conductive bar 10 may include a first sub-conductive bar 11, a second sub-conductive bar 12, and a third sub-conductive bar 13. The first sub-conductive bar 11 and the third sub-conductive bar 13 are used to insert and cooperate with the corresponding connection terminals 202, respectively. The second sub-conductive bar 12 is connected between the first sub-conductive bar 11 and the third sub-conductive bar 13 to separate the first sub-conductive bar 11 and the third sub-conductive bar 13, so that an avoidance space 14 is formed between the first sub-conductive bar 11 and the second sub-conductive bar 12 and between the third sub-conductive bar 13 and the second sub-conductive bar 12, and each avoidance space 14 is used to configure a connection terminal 202.

[0080] As shown in FIG. 30 and FIG. 31 , the energy storage module 201 may be provided with a foolproof slot 203. The shape of the foolproof slot is consistent with the shape of the conductive bar 10. When two energy storage modules 201 need to be connected in series, the first sub-conductive bar 11 is plugged into the positive electrode connection terminal 2029 of one of the two energy storage modules 201, the negative electrode connection terminal 2030 of the energy storage module 201 connected to the first sub-conductive bar 11 is located in the avoidance space 14 between the first sub-conductive bar 11 and the second sub-conductive bar 12, and the third sub-conductive bar 13 is plugged into the negative electrode connection terminal 2030 of the other of the two energy storage modules 201, and the positive electrode connection terminal 2029 of the energy storage module 201 connected to the third sub-conductive bar 13 is located in the avoidance space 14 between the third sub-conductive bar 13 and the second sub-conductive bar 12. The conductive bar 10 is located in the foolproof slot 203, and the foolproof slot 203 restricts the conductive bar 10 along the length, width, and thickness directions of the conductive bar 10. This setting can hide the conductive bar 10 in the foolproof slot 203, avoid the conductive bar 10 from being scratched, and facilitate the positioning of the conductive bar 10. In addition, the foolproof slot 203 can be set as a curved structure and assembled in cooperation with the conductive bar 10 to prevent the conductive bar 10 from being installed incorrectly, and play a foolproof role.

[0081] In some embodiments of the present disclosure, one end of the second sub-conductive bar 12 is connected to the first sub-conductive bar 11, the other end of the second sub-conductive bar 12 is connected to the third sub-conductive bar 13, and the first sub-conductive bar 11 and the third sub-conductive bar 13 extend in a direction away from each other. As shown in Figures 26 to 29 and 31, one end of the second sub-conductive bar 12 is connected to one end of the first sub-conductive bar 11, and the other end of the second sub-conductive bar 12 is connected to one end of the third sub-conductive bar 13. Furthermore, the second sub-conductive bar 12 is disposed perpendicular to the first sub-conductive bar 11 and the third sub-conductive bar 13. Such an arrangement can achieve the technical effect of forming an avoidance space 14 between the first sub-conductive bar 11 and the second sub-conductive bar 12 and between the third sub-conductive bar 13 and the second sub-conductive bar 12, so that the arrangement of the first sub-conductive bar 11, the second sub-conductive bar 12, and the third sub-conductive bar 13 is reasonable. Also, the conductive bar 10 can be configured as a "Z"-shaped structure. By configuring the conductive bar 10 as a "Z"-shaped structure and drawing out the positive electrode connection terminal 2029 and the negative electrode connection terminal 2030 from the same side of the energy storage module 201, the installation and disassembly of the electrical connection assembly 100 and the maintenance of the electrical connection assembly 100 are facilitated.

[0082] In some embodiments of the present disclosure, as shown in FIG. 26 to FIG. 28, the conductive bar 10 is provided with a positioning slot 15, which is suitable for positioning and alignment with the connecting terminal 202. Moreover, the positioning slot 15 penetrates the conductive bar 10 in the thickness direction of the conductive bar 10. The first sub-conductive bar 11 and the third sub-conductive bar 13 can be provided with a positioning slot 15, and the connecting terminal 202 can be provided with a limiting protrusion 2026. After the conductive bar 10 is inserted into the connecting terminal 202, the limiting protrusion 2026 extends into the positioning slot 15 of the conductive bar 10. Due to the cooperation of the limiting protrusion 2026 and the positioning slot 15, the conductive bar 10 can be securely inserted into the connecting terminal 202, which can avoid the connection terminal 202 and the conductive bar 10 from being separated, thereby further avoiding the virtual connection between the conductive bar 10 and the connecting terminal 202, and also preventing the conductive bar 10 from swinging relative to the connecting terminal 202.

[0083] In addition, both the first sub-conductive bar 11 and the third sub-conductive bar 13 may be provided with a plurality of positioning slots 15, and the connection terminal 202 may be provided with a plurality of limiting protrusions 2026. Through cooperation between the plurality of positioning slots 15 and the plurality of limiting protrusions 2026, the conductive bar 10 may be more securely inserted into the connection terminal 202, and the connection terminal 202 and the conductive bar 10 may be prevented from being separated, thereby further avoiding a virtual connection between the conductive bar 10 and the connection terminal 202, and further preventing the conductive bar 10 from swinging relative to the connection terminal 202.

[0084] In some embodiments of the present disclosure, as shown in Figures 23, 28, and 29, the insulating cover 20 may include an insulating cover body 21 and a first clamping portion 22, where the insulating cover body 21 is covered on the conductive bar 10 and is suitable for pressing the conductive bar 10, and in a first orientation of the insulating cover 20, when the electrical connection assembly 100 is placed in the orientation of Figure 23, the first orientation of the insulating cover 20 refers to the left-right direction in the figure, and the first clamping portion 22 is provided on at least one side of the insulating cover body 21, for example, in the first orientation, the first clamping portion 22 is provided on both sides of the insulating cover body 21, and the first clamping portion 22 is suitable for clamping with the connection terminal 202. By providing the first clamping portion 22 on the insulating cover body 21, the insulating cover 20 can be stably installed on the connection terminal 202, so that the insulating cover body 21 can be reliably pressed against the conductive bar 10, thereby further preventing the virtual connection between the conductive bar 10 and the connection terminal 202, and the insulating cover body 21 is covered on the conductive bar 10, which plays the role of insulation protection, can avoid the leakage of the electrical connection assembly 100, and can improve the safety of using the electrical connection assembly 100. At the same time, by clamping the insulating cover 20 and the connection terminal 202 together, the disassembly and assembly of the insulating cover 20 and the connection terminal 202 is simplified, which can improve the assembly efficiency of the insulating cover 20 and the connection terminal 202.

[0085] In some embodiments of the present disclosure, in the second direction of the insulating cover 20, when the electrical connection assembly 100 is placed in the direction shown in FIG. 23, the second direction of the insulating cover 20 refers to the front-rear direction shown in FIG. 23, and a shielding portion 23 is provided at the end of the insulating cover body 21 away from the conductive bar 10, and the shielding portion 23 is used to shield the conductive bar 10. As shown in FIG. 23, FIG. 27, and FIG. 29, the connection terminal 202 defines a plug slot 2023. As shown in FIG. 23 and FIG. 27, when the electrical connection assembly 100 is placed in the direction shown in FIG. 27, the upper end of the plug slot 2023 is open, and in the second direction of the insulating cover 20, the front end of the plug slot 2023 and the rear end of the plug slot 2023 are both open. The conductive bar 10 can be pushed into the plug-in slot 2023 of the connection terminal 202 from the open end of the plug-in slot 2023 to achieve plug-in alignment between the conductive bar 10 and the connection terminal 202. After the conductive bar 10 is inserted into the plug-in slot 2023, the insulating cover 20 is installed on the connection terminal 202. The shielding portion 23 can shield the open end of the plug-in slot 2023 in the second direction, thereby shielding the conductive bar 10 and further preventing leakage of the electrical connection assembly 100. In addition, the insulating cover 20 is located at the upper end of the plug-in slot 2023, and the insulating cover 20 can limit the position of the conductive bar 10, thereby preventing the conductive bar 10 from jumping out of the plug-in slot 2023.

[0086] In some embodiments of the present disclosure, as shown in Fig. 23, Fig. 26 to Fig. 28, an insulating sheath 30 is provided on the outer cover of the conductive bar 10, and the insulating sheath 30 has an insulating function. Moreover, the insulating sheath 30 can be made of insulating adhesive. Moreover, in the longitudinal direction of the conductive bar 10, at least a part of the structure of the first sub-conductive bar 11 and the third sub-conductive bar 13 is exposed outside the insulating sheath 30. By placing the insulating sheath 30 on the outside of the conductive bar 10, the electric leakage of the conductive bar 10 can be avoided, and the electric shock after the user touches the conductive bar 10 can be prevented, thereby further improving the safety of the electrical connection assembly 100.

[0087] The energy storage module 201 is provided with a connection terminal 202, and a plurality of energy storage modules 201 are provided in the energy storage cabinet. The plurality of energy storage modules 201 are stacked in order in the height direction of the energy storage cabinet, and each energy storage module 201 is provided with two connection terminals 202, the two connection terminals 202 are arranged in the width direction of the energy storage module 201, the two connection terminals 202 are arranged at the same end of the energy storage module 201, one of the two connection terminals 202 is configured as a positive connection terminal 2029 of the energy storage module 201, and the other of the two connection terminals 202 is configured as a negative connection terminal 2030 of the energy storage module 201. The electrical connection assembly 100 is used to electrically connect the two energy storage modules 201.

In the plugging process between the conductive bar 10 and the connection terminal 202, there is no need to use a tool such as a wrench to plug the conductive bar 10 into the connection terminal 202, which facilitates the docking of the conductive bar 10 and the connection terminal 202, improves the assembly efficiency of the conductive bar 10 and the connection terminal 202, thereby improving the assembly efficiency of the energy storage cabinet, and also reduces the installation cost of the conductive bar 10 and the connection terminal 202. At the same time, the insulating cover 20 is connected to the connection terminal 202, and the insulating cover 20 presses the conductive bar 10. By pressing the insulating cover 20 against the conductive bar 10, the conductive bar 10 can be securely inserted into the connection terminal 202, which can avoid virtual connection between the conductive bar 10 and the connection terminal 202, prevent arc discharge, improve the safety of the electrical connection assembly 100, and also improve the safety of the energy storage module 201, thereby improving the safety of the energy storage cabinet. In addition, the insulating cover 20 is an insulating member, and the insulating cover 20 is covered on the conductive bar 10, which can avoid the conductive bar 10 from being exposed, avoid electric leakage, and improve high voltage safety.

[0089] In some embodiments of the present disclosure, as shown in Fig. 31, two connection terminals 202 are provided on the energy storage module 201, one of which is connected to the conductive bar 10 and the other connection terminal 202 is away from the conductive bar 10. Two connection terminals 202 are provided on each energy storage module 201, one of which is connected to the conductive bar 10 and the other connection terminal 202 is located in the avoidance space 14 formed by the conductive bar 10, so as to keep the connection terminals 202 away from the conductive bar 10 and avoid interference between the connection terminals 202 and the conductive bar 10. The two connection terminals 201 are disposed at the same end of the energy storage module 201, and the two connection terminals 201 are disposed adjacent to the same side of the energy storage module 201. It may also be seen that the energy storage module 201 is provided with a positive connection terminal 2029 and a negative connection terminal 2030, the positive connection terminal 2029 and the negative connection terminal 2030 being disposed adjacent to the same side of the energy storage module 201.

[0091] In some embodiments of the present disclosure, as shown in Fig. 26 and Fig. 27, the connection terminal 202 may include a conductive elastic piece 2021 and an insulating terminal body 2022, the terminal body 2022 defines an insertion slot 2023, the conductive elastic piece 2021 is arranged in the insertion slot 2023, and the conductive bar 10 is inserted into the insertion slot 2023 and contacts the conductive elastic piece 2021. Furthermore, when the electrical connection assembly 100 is placed in the direction shown in Fig. 27, the upper end of the insertion slot 2023 is open, and in the second direction of the insulating cover 20, the front end and the rear end of the insertion slot 2023 are both open, and the conductive bar 10 is pushed into the insertion slot 2023 of the connection terminal 202 from the open end of the insertion slot 2023 to bring the conductive elastic piece 2021 into contact with the conductive bar 10, thereby achieving an electrical connection between the conductive bar 10 and the conductive elastic piece 2021.

[0092] Further, as shown in Figures 26 and 27, the conductive elastic piece 2021 may include a first conductive elastic piece 2024 and a second conductive elastic piece 2025, wherein the first conductive elastic piece 2024 and the second conductive elastic piece 2025 are arranged opposite each other in a first direction of the connection terminal 202, the first direction of the connection terminal 202 coincides with the first direction of the insulating cover 20, and the conductive bar 10 is suitable to be inserted between the first conductive elastic piece 2024 and the second conductive elastic piece 2025. In addition, there are a plurality of first conductive elastic pieces 2024 and a plurality of second conductive elastic pieces 2025, and the plurality of first conductive elastic pieces 2024 and the plurality of second conductive elastic pieces 2025 are arranged in sequence along the second direction of the connection terminal 202, and the plurality of first conductive elastic pieces 2024 and the plurality of second conductive elastic pieces 2025 correspond to each other one by one, and the second direction of the connection terminal 202 is consistent with the second direction of the insulating cover 20. After the conductive bar 10 is pushed into the plug-in slot 2023 of the connection terminal 202 from the open end of the plug-in slot 2023, the conductive bar 10 is sandwiched between the first conductive elastic piece 2024 and the second conductive elastic piece 2025, which ensures that the conductive bar 10 is in reliable contact with both the first conductive elastic piece 2024 and the second conductive elastic piece 2025, thereby further avoiding the virtual connection between the conductive bar 10 and the connection terminal 202.

[0093] 26 and 27, the conductive bar 10 is provided with a positioning slot 15, and at least one of the first conductive elastic piece 2024 and the second conductive elastic piece 2025 has a limiting protrusion 2026, which is suitable for extending into the positioning slot 15 of the conductive bar 10.

Through cooperation between the limiting protrusion 2026 and the positioning slot 15, the conductive bar 10 can be securely inserted into the connection terminal 202, and the conductive elastic piece 2021 and the conductive bar 10 can be prevented from being separated, thereby further preventing a virtual connection between the conductive bar 10 and the conductive elastic piece 2021, and also preventing the conductive bar 10 from swinging relative to the connection terminal 202. In addition, by making the limiting protrusion 2026 extend into the positioning slot 15 of the conductive bar 10, it can be determined whether the conductive bar 10 is inserted in a predetermined position.

Furthermore, one end of the conductive member 2027 extends into the plug-in slot 2023 and is connected to the conductive elastic piece 2021. When the connection terminal 202 is installed in the energy storage module 201, the conductive member 2027 is connected between the conductive elastic piece 2021 and the energy storage module 201, so as to realize an electrical connection between the connection terminal 202 and the energy storage module 201.

By clamping the second clamping portion 2028 with the first clamping portion 22 so as to improve the efficiency of disassembly and assembly of the insulating cover 20 and the connecting terminal 202, it is easy to install the insulating cover 20 on the connecting terminal 202 and easy to remove the insulating cover 20 from the connecting terminal 202. However, the present disclosure is not limited thereto, and the insulating cover 20 and the connecting terminal 202 can also be assembled by bolts. The specific assembly method of the insulating cover 20 and the connecting terminal 202 can be selected according to the actual situation.

[0096] Further, as shown in FIG. 23 and FIG. 26, the first clamping portion 22 is one of the clamping hole and the clamping hook, and the second clamping portion 2028 is the other of the clamping hole and the clamping hook.
