Description

Technical Field

[0001] This invention relates to the field of energy storage module technology, and in particular to a long-cycle soft-pack energy storage module. Background Technology

[0002] With the rapid development of science and technology and the rise of the new energy industry, battery technology, as a core power source, is being used more and more widely in various fields. Among them, soft-pack battery modules, with their unique advantages, are gradually becoming an important choice in the field of energy storage. Long-cycle soft-pack energy storage modules, as an advanced product in this field, have background technologies covering several key aspects.

[0003] A soft-pack energy storage module, with publication number CN218827721U, includes several soft-pack cells. Each soft-pack cell has a tab at its upper and lower ends. Adjacent soft-pack cells are connected in series via either the upper or lower tab. The two connected tabs are fixed by a tab connecting plate, which is fixed to two adjacent connecting brackets. A heat-conducting bracket is positioned between adjacent soft-pack cells. Side insulating plates and side brackets are sequentially arranged on the outer sides of the soft-pack cells at both ends of the module. The side brackets, side insulating plates, connecting brackets, and heat-conducting brackets are connected and fixed by module connecting studs. Upper and lower insulating plates are also provided on the upper and lower sides of the module, respectively. The soft-pack module also includes two copper busbars, one end connected to a tab located on the outer soft-pack cell, and the other end fixed to the side bracket. An insulator is also provided between the side bracket and the copper busbar. The module has a compact structure and is easy to assemble.

[0004] The aforementioned existing technologies are limited in function and lack thermal insulation protection. The performance of pouch energy storage modules is closely related to their operating temperature. Within a suitable temperature range, the energy storage and release efficiency of the energy storage module is optimal. If thermal insulation is lacking, the internal temperature of the module is easily affected by the external environment, leading to performance degradation. Furthermore, temperature fluctuations can accelerate chemical reactions inside the battery, potentially causing loss of active materials and degradation of the battery structure. Long-term lack of thermal insulation will shorten the cycle life of pouch energy storage modules, thus requiring corresponding improvements. Summary of the Invention

[0005] The purpose of this invention is to provide a long-cycle soft-pack energy storage module to solve the problem mentioned in the background art that the existing soft-pack energy storage modules have poor temperature protection performance during use, which affects their use.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a long-cycle soft-pack energy storage module, comprising a soft-pack energy storage module body and a sleeve plate, wherein the sleeve plate is sleeved on the bottom outer side of the soft-pack energy storage module body, and fixing holes are evenly arranged on the outer side of the sleeve plate;

[0007] It also includes: heat sinks are evenly connected to the top of the main body of the soft-pack energy storage module, and heat conduction grooves are opened on each heat sink; insulation boards are evenly connected to the top of the sleeve plate, and a fixing mechanism is provided between the insulation board and the sleeve plate; the insulation board is made of aluminum alloy.

[0008] Preferably, four insulation boards are provided and distributed on the four outer sides of the soft-pack energy storage module body.

[0009] Preferably, each of the insulation boards has an insulation cavity inside, and the insulation cavity is uniformly connected with transverse support columns and longitudinal support columns.

[0010] Preferably, multiple transverse and longitudinal support columns are provided in the insulation cavity, arranged in a transverse manner, and the transverse and longitudinal support columns are arranged in a staggered manner, with insulation cotton filling the interlayer between the transverse and longitudinal support columns.

[0011] Preferably, the fixing mechanism includes plug-in blocks, and each plug-in block is fixed to the bottom end of the insulation board. One end of each plug-in block extends into the plug-in hole. Each fixing hole is located inside the sleeve plate. Each plug-in block has an internal cavity, and a return spring is connected inside the internal cavity. One end of the return spring is connected to a moving plate, and one end of the moving plate is connected to a locking block. One end of the locking block passes through the fixing hole.

[0012] Preferably, guide posts extend through both sides of the interior of the movable plate, and the movable plate is slidably connected to the guide posts.

[0013] Compared with the prior art, the beneficial effects of the present invention are: the long cycle soft pack energy storage module not only has a better temperature protection effect, enabling the power battery to continue to work in low temperature environments, but also the temperature protection structure is detachable, avoiding the impact of high temperature environments on the use of the power battery.

[0014] By connecting insulation boards to all four sides of the soft-pack energy storage module body, the insulation boards are made of aluminum alloy, which is lightweight, high-strength, and has good insulation effect. This enhances the insulation effect of the soft-pack energy storage module body, so that the soft-pack energy storage module body can maintain good endurance in low-temperature environments and helps to extend the service life of the soft-pack energy storage module body.

[0015] The insulation cotton is laid in the insulation cavity inside the insulation board, which can effectively reduce heat transfer, further enhance the insulation performance of the insulation board and the main body of the soft-pack energy storage module, reduce energy consumption, and thus improve the energy efficiency and service life of the main body of the soft-pack energy storage module. Horizontal and vertical support columns are arranged in the insulation cavity to provide internal support for the main body of the soft-pack energy storage module, so that the main body of the soft-pack energy storage module has high strength and support, and plays a certain protective role for the main body of the soft-pack energy storage module.

[0016] By inserting the plug-in block on the insulation board into the plug-in hole, the return spring is compressed during the insertion process, and the locking block is retracted into the internal cavity. When the plug-in block is fully inserted, the return spring returns to its original position, pushing the locking block into the fixing hole, thus fixing the insulation board onto the sleeve plate and making the insulation board adhere to the outer wall of the soft-pack energy storage module body, providing heat insulation and protection for the soft-pack energy storage module body. Later, the locking block can be pushed by the ejector pin to disengage it from the fixing hole, and the insulation board can be removed for later inspection, maintenance and replacement.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1-5 The present invention provides the following technical solution: Example 1

[0026] To address the issue that existing soft-pack energy storage modules, while exhibiting good insulation, suffer from high energy consumption in low-temperature environments, thus affecting their performance, the following technical solution is proposed. Please refer to the following for details. Figure 1 , Figure 2 , Figure 4 A long-cycle soft-pack energy storage module includes a soft-pack energy storage module body 1 and a sleeve plate 3. The sleeve plate 3 is sleeved on the bottom outer side of the soft-pack energy storage module body 1, and fixing holes 301 are evenly arranged on the outer side of the sleeve plate 3. It also includes: heat sinks 2 are evenly connected to the top of the soft-pack energy storage module body 1, and heat conduction grooves 201 are opened on each heat sink 2. The top of the sleeve plate 3 is evenly connected to the insulation plate 4. There are four insulation plates 4, which are distributed on the four outer sides of the soft-pack energy storage module body 1. Each insulation plate 4 has an insulation cavity 401 inside, and horizontal support columns 402 and vertical support columns 403 are evenly connected inside the insulation cavity 401. There are multiple horizontal support columns 402 and vertical support columns 403 in the insulation cavity 401, which are horizontally distributed. The horizontal support columns 402 and vertical support columns 403 are staggered. The interlayer between the horizontal support columns 402 and vertical support columns 403 is filled with insulation cotton 404.

[0027] In this embodiment, insulation plates 4 are connected to all four sides of the soft-pack energy storage module body 1. The insulation plates 4 are made of aluminum alloy, which is lightweight, high-strength, and has good insulation properties, thus enhancing the insulation performance of the soft-pack energy storage module body 1. This allows the soft-pack energy storage module body 1 to maintain good battery life in low-temperature environments. Insulation cotton 404 is laid in the insulation cavity 401 inside the insulation plates 4, effectively reducing heat transfer and further enhancing the insulation performance of the insulation plates 4 and the soft-pack energy storage module body 1. This reduces heat exchange between the soft-pack energy storage module body 1 and the external environment, thereby maintaining the soft-pack energy storage module's performance. The relatively stable internal temperature of the soft-pack energy storage module body 1 makes the energy storage and release efficiency of the soft-pack energy storage module body 1 higher, which helps to improve the overall performance of the soft-pack energy storage module body 1. Horizontal support columns 402 and vertical support columns 403 are arranged in the insulation cavity 401 to provide internal support for the soft-pack energy storage module body 1, giving it high strength and support, and providing a certain degree of protection. Multiple heat sinks 2 are installed on the top of the soft-pack energy storage module body 1 to effectively conduct heat under high-intensity use, further enhancing the protection of the soft-pack energy storage module body 1. Example 2

[0028] This embodiment differs from Embodiment 1 in that the fixing mechanism 5 allows for the free assembly and disassembly of the insulation board 4, facilitating subsequent inspection and maintenance. Therefore, the following technical solution is disclosed; please refer to the details. Figure 1 , Figure 2 , Figure 3 , Figure 5 A fixing mechanism 5 is provided between the insulation board 4 and the sleeve plate 3. The insulation board 4 is made of aluminum alloy. The fixing mechanism 5 includes a plug-in block 501, and the plug-in block 501 is fixed to the bottom end of the insulation board 4. One end of the plug-in block 501 extends into the plug-in hole 302. The fixing hole 301 is set inside the sleeve plate 3. The plug-in block 501 has an internal cavity 502, and a return spring 504 is connected inside the internal cavity 502. One end of the return spring 504 is connected to a moving plate 503, and one end of the moving plate 503 is connected to a locking block 506. One end of the locking block 506 passes through the fixing hole 301. Guide posts 505 pass through both sides inside the moving plate 503. The moving plate 503 and the guide posts 505 are slidably connected.

[0029] In this embodiment, during use, the insertion blocks 501 on multiple insulation boards 4 are inserted into the insertion holes 302 respectively. During the insertion process, the locking block 506 contacts the inner wall of the insertion hole 302. Pressing the locking block 506 compresses the return spring 504 and retracts the locking block 506 into the internal cavity 502. After the insertion blocks 501 are fully inserted, the return spring 504 returns to its original position, pushing the locking block 506 into the fixing hole 301, thus fixing the insulation board 4 in place. On the sleeve plate 3, during the movement of the locking block 506, the moving plate 503 slides along the guide post 505. The guide post 505 can be used to limit and guide the movement of the locking block 506, so that the insulation plate 4 is attached to the outer wall of the soft-pack energy storage module body 1, which can provide heat insulation and protection for the soft-pack energy storage module body 1. Later, the locking block 506 is pushed by the ejector pin to disengage it from the fixing hole 301, so that the insulation plate 4 can be removed for later inspection, maintenance and replacement.
