DETAILED DESCRIPTION

[0037] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0038] In the related art, the energy storage device includes a shell and a plurality of batteries disposed in the shell. An electrical module and a cooling module are also disposed in the shell, and the electrical module is adjacent to the cooling module.

[0039] However, the electrical modules and cooling modules in the above energy storage device are distributed in a mixed manner, which makes it easy for the electrical modules and cooling modules to affect each other during installation, use and maintenance, resulting in low overall safety of the energy storage device; and each component is fastened with multiple bolts, which makes the fastening process of each component more complicated, so that the overall production efficiency of the energy storage device is low.

[0040] Based on this, the embodiment of the present application provides an energy storage device, which is provided with: a frame, which has a plurality of installation cavities; a plurality of battery assemblies, the battery assembly includes a body, an electrical module and a cooling module, the body is provided on the cooling module, and the body and the cooling module are at least partially located in the installation cavity; the cooling module has an interface, the electrical module is electrically connected to the body, and the electrical module and the interface are respectively located on opposite sides of the body. Thus, the interface of the electrical module and the cooling module in the frame is effectively separated, so that the electrical module and the cooling module are not easily affected by each other during installation, use and maintenance, which greatly improves the overall safety and reliability of the device, and solves the problem of low safety of energy storage devices in the prior art.

[0041] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0042] like Figure 1 and Figure 2 As shown, an energy storage device provided in an embodiment of the present application includes:

[0043] A frame 100 having a plurality of mounting cavities 110;

[0044] A plurality of battery assemblies 200, wherein the battery assemblies 200 include a body, an electrical module 300 and a cooling module 400, wherein the body is disposed on the cooling module 400, and both the body and the cooling module 400 are at least partially located in the mounting cavity 110;

[0045] The cooling module 400 has an interface, the electrical module 300 is electrically connected to the body, and the electrical module 300 and the interface are respectively located on two opposite sides of the body.

[0046] The frame 100 may be a cuboid, a cube, a rhombus, a hexagon or other shapes, which are not limited. The frame 100 is provided with a plurality of reinforcing ribs 120, which are arranged obliquely and can be fixed to the frame 100 by welding, screwing or other methods. The reinforcing ribs 120 increase the stability of the frame 100 itself and increase the load bearing capacity.

[0047] It should be noted that the main body and the cooling module 400 may be completely accommodated in the installation cavity 110 , or the main body and the cooling module 400 may be partially accommodated in the installation cavity 110 , and there is no limitation to this.

[0048] During installation, it is only necessary to install the body, the electrical module 300 and the cooling module 400 together on the frame 100. At this time, the interfaces on the electrical module 300 and the cooling module 400 in the frame 100 can be effectively separated, so that the electrical module 300 and the cooling module 400 are not easily affected by each other during installation, use and maintenance, which greatly improves the overall safety and reliability of the energy storage device and solves the problem of low safety of the energy storage device in the prior art.

[0049] like Figure 1 As shown, in some embodiments, the frame 100 is hollow inside, and a plurality of partitions 600 are disposed on the frame 100 , and the plurality of partitions 600 divide the inside of the frame 100 into a plurality of installation cavities 110 ;

[0050] Each battery assembly 200 is plugged into each mounting cavity 110 .

[0051] Specifically, each separator 600 is spaced apart inside the frame 100 to divide the frame 100 into a plurality of mounting cavities 110, and the mounting cavities 110 are open at both ends. When installing, the battery assembly 200 only needs to be inserted into the mounting cavity 110 from any end.

[0052] like Figure 1 and Figure 2 As shown, further, a plurality of limiting members 700 are provided on the frame 100 , and the limiting members 700 are provided at one end of the installation cavity 110 to limit the battery assembly 200 in the installation cavity 110 .

[0053] The stopper 700 may be in the form of a plate, strip or other structure, and each stopper 700 is disposed at one end of each mounting cavity 110. The stopper 700 may be fixed to the frame 100 by screwing, clamping, welding or other methods, so that the stopper 700 closes the opening of one end of the mounting cavity 110.

[0054] Therefore, during installation, the battery assembly 200 only needs to be fully inserted into the installation cavity 110 from the end away from the limiting member 700, thereby reducing the possibility of the battery assembly 200 falling out of the installation cavity 110 during the insertion process.

[0055] Based on this, the battery assembly 200 is installed in a quick pulling manner, which can improve production efficiency, increase space utilization, effectively reduce installation difficulty, increase energy density and reduce costs.

[0056] like Figure 2 As shown, the electrical module 300 includes a plurality of groups of male terminals 310 and female terminals 320 that cooperate with each other. The female terminals 320 are arranged on the battery, and the male terminals 310 are arranged on the limiting member 700 .

[0057] In this embodiment, the electrical module 300 includes two sets of male terminals 310 and female terminals 320 . Both female terminals 320 are arranged on the battery, and the female terminals 320 penetrate to the outside of the shell 210 . Both male terminals 310 are arranged on the limiting member 700 .

[0058] The limiting member 700 is provided with a plurality of installation openings 710 , and each male end 310 is correspondingly embedded in each installation opening 710 .

[0059] When installing the battery assembly 200, the end of the battery assembly 200 with the female end 320 is inserted from the end of the installation cavity 110 away from the stopper 700, so that when the battery assembly 200 is completely inserted into the installation cavity 110, each female end 320 is respectively plugged and matched with each male end 310, thereby completing the installation of the battery electrical module 300. Subsequently, the external circuit only needs to be connected to the male end 310 to connect the battery to the external circuit.

[0060] During implementation, the male end 310 and the female end 320 may also be provided with magnetism to improve the convenience of connecting the male end 310 and the female end 320 to each other.

[0061] like Figure 1 As shown, in some embodiments, the body further includes a shell 210 and a battery, the shell 210 is disposed on the cooling module 400, the battery is disposed in the shell 210, and the electrical module 300 is electrically connected to the battery.

[0062] Specifically, the housing 210 is an open structure at one end, and the battery is accommodated in the housing 210, and the two are adapted, and the battery is not shown in the drawings. The open end of the housing 210 is attached to the cooling module 400, so that the battery is in contact with the cooling module 400. The housing 210 can be fixed to the cooling module 400 by screwing, pinning or other means, so that the housing 210, the battery and the cooling module 400 form a whole.

[0063] During use, the battery can be protected by the housing 210 to improve the safety of the battery.

[0064] It can be understood that when the battery assembly 200 is entirely located in the installation cavity 110 , it is only necessary to lock any one of the housing 210 , the battery, and the cooling module 400 to lock the battery assembly 200 entirely in the installation cavity 110 .

[0065] The electric module 300 passes through the housing 210 , and the electric module 300 is electrically connected to the battery.

[0066] like Figure 1 and Figure 3 As shown, in some embodiments, the cooling module 400 includes a liquid cooling plate 410 and a cooling pipe, and the housing 210 is connected to the liquid cooling plate 410;

[0067] The cooling pipe is disposed in the liquid cooling plate 410 , and the end of the cooling pipe extends to the outside of the liquid cooling plate 410 to form an interface.

[0068] At this time, the open end of the housing 210 is fixed to the liquid cooling plate 410 , so that the battery is in contact with the liquid cooling plate 410 .

[0069] It should be noted that the cooling module 400 can be configured as an air-cooled form or a liquid-cooled form. In this embodiment, the cooling module 400 is configured as a liquid-cooled form.

[0070] Specifically, the cooling module 400 includes a liquid cooling plate 410 and a cooling pipe arranged inside the liquid cooling plate 410. The cooling pipe is not shown in the accompanying drawings. The cooling pipe can be in the form of a coil. The cooling pipe has a liquid inlet 420 and a liquid outlet 430, and the liquid inlet 420 and the liquid outlet 430 both extend to the outside of the liquid cooling plate 410 and are both located on the side of the main body away from the electrical module 300.

[0071] When in use, the coolant can be input into the cooling pipe from the liquid inlet 420 and then output from the liquid outlet 430, so that the cooling pipe can contact the battery through the liquid cooling plate 410, thereby dissipating the heat of the battery and improving the battery use effect and safety.

[0072] In addition, the electrical module 300 is arranged at one end of the battery facing the limit member 700, and the liquid inlet 420 and the liquid outlet 430 of the cooling tube are both arranged at the end of the liquid cooling plate 410 away from the electrical module 300, so that the liquid inlet 420 / liquid outlet 430 in the electrical module 300 and the cooling module 400 are distributed at both ends of the battery assembly 200, thereby separating the electrical module 300 and the cooling module 400, that is, having the effect of dry and wet separation, thereby improving the overall safety of the energy storage device.

[0073] like Figure 1 and Figure 3 As shown, further, a plurality of positioning holes are provided on the cooling module 400 , and the partition 600 is provided with a locking member 500 , which is used to cooperate with the positioning holes to lock the battery assembly 200 in the installation cavity 110 .

[0074] In this embodiment, the two positioning holes form a pair, and the two positioning holes in the same pair are respectively located at the two ends of the cooling module 400 along the direction of insertion of the battery assembly 200. Several pairs of positioning holes can be provided on the same cooling module 400, and there is no limitation on this. In this embodiment, the positioning holes are provided on the liquid cooling plate 410 in the cooling module 400, and the positioning holes are not shown in the drawings.

[0075] The number of the locking members 500 is set to correspond to the number of the positioning holes, so that each locking member 500 can be matched with each positioning hole to lock the cooling module 400 and the battery assembly 200 in the installation cavity 110.

[0076] Exemplarily, the locking member 500 can be an elastic latch, specifically including a latch and a spring, wherein the latch is slidably disposed on the partition 600, and the two ends of the spring are respectively connected to the latch and the partition 600, so that the spring can push the latch to automatically slide toward the battery assembly 200 to be plugged into the positioning hole, thereby quickly locking the cooling module 400 and the battery assembly 200 as a whole in the installation cavity 110.

[0077] Of course, the latch in the locking member 500 can also be rotatably connected to the partition 600, and a torsion spring is added to the rotating part of the latch to control the latch to automatically plug and fit into the positioning hole. The locking member 500 can also be set to other structures, and only needs to lock the positioning hole, which is not limited.

[0078] During installation, after the battery assembly 200 is inserted into the installation cavity 110, the locking piece 500 cooperates with the positioning hole on the cooling module 400 to quickly lock the battery assembly 200 in the installation cavity 110, thereby reducing the use of screws or bolts and improving the production efficiency of the energy storage device.

[0079] like Figure 1 and Figure 3 As shown, in some embodiments, the partition 600 includes a partition plate 610 and a side plate 620, the partition plate 610 is connected to the side plate 620, and a plurality of partition plates 610 divide the interior of the frame 100 into a plurality of installation cavities 110;

[0080] like Figure 4 As shown, the side plate 620 is located at the side of the installation cavity 110 , and the side plate 620 is used to guide the insertion process of the battery assembly 200 .

[0081] In this embodiment, two partitions 600 are correspondingly provided in the same installation cavity 110, so that the two partitions 600 are located at both ends of the installation cavity 110 along the plugging direction of the vertical battery assembly 200, and the partition plate 610 can be fixed to the frame 100 by screwing, welding or other methods.

[0082] The side plate 620 may be integrally formed with the partition plate 610 , and the side plate 620 may also be fixed to the partition plate 610 by welding, bonding or other methods. The side plate 620 is located at the side of the installation cavity 110 . At this time, the locking member 500 may be disposed on the partition plate 610 .

[0083] Furthermore, a limiting strip 621 is provided on one side of the side plate 620 facing the battery assembly 200, and the limiting strip 621 extends along the plugging direction of the battery assembly 200. During the plugging process of the battery assembly 200, the battery assembly 200 can also be guided by the side plate 620 and the limiting strip 621, so that the plugging process of the battery assembly 200 is smoother and the installation convenience is improved.

[0084] During implementation, a plurality of limiting protrusions may be further formed on the side of the side plate 620 facing the battery assembly 200, and the limiting protrusions are distributed along the plugging direction of the battery assembly 200, so as to further guide the installation process of the battery assembly 200 through the limiting protrusions.

[0085] During implementation, for example, the housing 210 is located above the liquid cooling plate 410, and the width of the housing 210 is smaller than the width of the liquid cooling plate 410, so that the battery assembly 200 is in a stepped structure with a small top and a large bottom. In this regard, the limit strip 621 is correspondingly arranged at the stepped portion of the battery assembly 200 to improve the guiding effect of the battery assembly 200.

[0086] In summary, when installing the energy storage device provided in the embodiment of the present application, each battery assembly 200 can be quickly locked in the installation cavity 110 by the locking member 500, without the need to use multiple bolts for fastening, so that the installation process is more convenient and the production efficiency of the energy storage device is higher; and the electrical module 300 and the cooling module 400 in the frame 100 are effectively separated, which greatly improves the overall safety and reliability of the energy storage device and solves the problem of low safety of the energy storage device in the prior art.

[0087] Finally, it should be noted that those skilled in the art will readily conceive of other embodiments of the present invention after considering the specification and practicing the invention disclosed herein. The present invention is intended to cover any variations, uses or adaptations of the present invention, which follow the general principles of the present invention and include common knowledge or customary technical means in the art not disclosed by the present invention, are not limited to the precise structure described above and shown in the drawings, and may be modified and changed in various ways without departing from the scope thereof.
