Technical Field
[0001] The utility model relates to the technical field of energy storage battery packs, and in particular to an energy storage module wiring structure compatible with different types of battery cells. Background Art
[0002] Energy storage battery pack data collection is an important consideration in the design and operation of energy storage systems. In energy storage systems, battery pack data collection is directly related to the safety and stability of the system, and the accuracy and reliability of the sampling line are crucial. The main function of the sampling line is to collect data such as voltage, temperature, internal resistance, and active and passive balancing management of battery cells; BMS can use this data to monitor battery status and manage normal battery operation.
[0003] Therefore, when connecting the sampling harness, the energy storage battery pack needs to pay attention to the accuracy of the connection position of the sampling harness. Whether the sampling line and bus are combined into one (hereinafter referred to as CCS) or the sampling harness and bus are separated, attention needs to be paid to accuracy. Especially for the battery modules using CCS at present, the CSS shape and appearance are consistent, and only the silk screen logo is distinguished. The modules in the battery pack of the same structural type are often only different in the starting position of the positive and negative polarity. Before welding the module, it is necessary to manually identify the drawings to determine the type of CCS currently required. If it is identified after welding, there is a risk of dismantling and re-welding, and it is easy to produce defective products. The modules also need to be checked when they are put into the box. If the wrong type of module is placed, the jumper bar will be connected in parallel or short-circuited. The sampling line and bus are separated, which is prone to incorrect bus placement, incorrect connection position of the voltage sampling line and the temperature sampling line, which affects BMS monitoring and management.
[0004] With the development of the energy storage industry, the number of cells in a single battery pack is increasing, and the safety requirements are getting higher and higher. Now, one cell in the battery pack is gradually equipped with one temperature collection point, and the connection points of the sampling harness are also increasing, and the defective rate will also increase. For this reason, we propose an energy storage module wiring structure that is compatible with different types of cells to solve the above problems. Summary of the invention
[0005] The purpose of the utility model is to solve the shortcomings of the prior art in the above-mentioned background technology and to propose an energy storage module wiring structure that is compatible with different types of battery cells.
[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] A wiring structure for an energy storage module compatible with different models of battery cells, including a first connecting rod and a battery pack housing. The first connecting rod is installed inside the battery pack housing. A first guide rail is sleeved outside the first connecting rod. A second connecting rod is provided on the right side of the first connecting rod, and a second guide rail is sleeved outside the second connecting rod. A third connecting rod is provided on the right side of the second connecting rod, and a third guide rail is sleeved outside the third connecting rod. A fifth connecting rod is provided on the right side of the third connecting rod, and a fourth guide rail is sleeved outside the fifth connecting rod. Visual number block assemblies are respectively arranged inside the second connecting rod, the first connecting rod, the third connecting rod and the fifth connecting rod. Spacing adjustment assemblies are symmetrically distributed on the left and right sides of the back of the second connecting rod. The first connecting rod and the first guide rail are connected by a connecting pin shaft.
[0008] In this device, an auxiliary tooling for splicing and adjustable energy storage battery packs is provided to solve the problem of relying solely on manual drawing checking or photo recognition after processing to determine accuracy. This device can assist manual connection and check the position of sampling wire harnesses during the manufacturing process before the result is formed, reducing the labor and material costs caused by rework afterwards. Even if problems occur during the process, it can be adjusted immediately, greatly saving rework time.
[0009] Preferably, a handle is welded on the side wall of the battery pack housing, and the handles are symmetrically distributed at the left and right ends of the front of the battery pack housing.
[0010] Preferably, the visual number block assembly includes a number plate fixing shaft, a visual block fixing shaft, a number plate body and a visual block body. The number plate fixing shaft is inserted into the second connecting rod, the first connecting rod, the third connecting rod and the fifth connecting rod, and a number plate body is connected to the outside of the number plate fixing shaft.
[0011] Preferably, visual block fixing shafts are distributed on the side of the number plate fixing shaft, and a visual block body is connected to the outside of the visual block fixing shaft.
[0012] Preferably, the spacing adjustment assembly includes a fourth connecting rod, a spacing adjustment block and a spacing adjustment fixing shaft. The end of the fourth connecting rod is connected to the back of the second guide rail. A spacing adjustment block is installed above the fourth connecting rod, and a spacing adjustment fixing shaft is inserted into the side of the spacing adjustment block.
[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0014] By setting a simple multi-stage linkage structure, the device changes the visual window to display the number plate to match the type of the current required module or battery pack, implementing point-to-point auxiliary indication. The inspection work can be completed while installing the wire harness and the busbar, greatly improving the assembly accuracy rate, reducing the quality control difficulty and the defective rate. For longer modules or battery packs, the splicing module can be increased for adaptation, and the guide rail spacing can be telescoped to be compatible with battery modules and battery packs of different models of square battery cells as required.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0021] Referring to Figures 1-4 , a wiring structure for an energy storage module that is compatible with different models of battery cells includes a first connecting rod 1 and a battery pack housing 12. The first connecting rod 1 is installed inside the battery pack housing 12. A first guide rail 2 is sleeved outside the first connecting rod 1. A second connecting rod 3 is provided on the right side of the first connecting rod 1, and a second guide rail 4 is sleeved outside the second connecting rod 3. A third connecting rod 5 is provided on the right side of the second connecting rod 3, and a third guide rail 6 is sleeved outside the third connecting rod 5. A fifth connecting rod 10 is provided on the right side of the third connecting rod 5, and a fourth guide rail 11 is sleeved outside the fifth connecting rod 10. Visible number block assemblies 7 are respectively provided inside the second connecting rod 3, the first connecting rod 1, the third connecting rod 5, and the fifth connecting rod 10. Spacing adjustment components 8 are symmetrically distributed on the left and right sides of the back of the second connecting rod 3. The first connecting rod 1 and the first guide rail 2 are connected by a connecting pin shaft 9. Similarly, the second connecting rod 3 and the second guide rail 4, the third connecting rod 5 and the third guide rail 6, and the fifth connecting rod 10 and the fourth guide rail 11 are all connected by a connecting pin shaft 9. Through transmission, corresponding actions are completed to complete the adaptation to the module.
[0022] This device is also applicable to the wiring and inspection of a single module. Before welding a single module, it is necessary to place a bus bar or the corresponding CCS. Before placing the bus bar, this application can be preferentially placed. It can not only avoid the misplacement of the bus bar through physical limit, but also support the indication and assistance of wire harness connection after welding, with a dual-purpose effect. For modules using CCS, after placing the CCS, this application can directly check the type and position of the currently placed CCS to avoid rework caused by checking and judging after welding. Compared with the difficulty of manually judging whether the current module operation is correct by visually checking the drawing, the auxiliary indication mark provided by this application can directly compare point-to-point with the constraint, and the scheme is simpler and more direct, greatly improving the accuracy and inspection efficiency in the actual manufacturing process.
[0023] The main structural part of this application is made of phenolic plastic. On the premise of ensuring good insulation, safe operation can be carried out. Phenolic plastic also has relatively high strength and a relatively long service life.
[0024] Further, referring to Figure 3 It can be known that a handle 13 is welded on the side wall of the battery pack housing 12, and the handles 13 are symmetrically distributed at the left and right ends of the front of the battery pack housing 12. Through the setting of the two groups of handles 13, it is convenient for the staff to transport the battery pack housing 12.
[0025] Further, referring to Figure 1 It can be known that the visible number block assembly 7 includes a number plate fixing shaft 701, a visible block fixing shaft 702, a number plate body 703 and a visible block body 704. The number plate fixing shaft 701 is inserted into the interiors of the second connecting rod 3, the first connecting rod 1, the third connecting rod 5 and the fifth connecting rod 10. A number plate body 703 is connected to the outside of the number plate fixing shaft 701. During use, through the mutual cooperation of the number plate fixing shaft 701 and the number plate body 703, the installation of the number plate body 703 can be realized.
[0026] Further, referring to Figure 1 It can be known that visible block fixing shafts 702 are distributed on the sides of the number plate fixing shaft 701, and a visible block body 704 is connected to the outside of the visible block fixing shaft 702. During use, through the mutual cooperation of the visible block fixing shaft 702 and the visible block body 704, the installation of the visible block body 704 can be realized.
[0027] Further, referring to Figure 1It can be known that the spacing adjustment component 8 includes a fourth connecting rod 801, a spacing adjustment block 802 and a spacing adjustment fixed shaft 803. The end of the fourth connecting rod 801 is connected to the back of the second guide rail 4. Above the fourth connecting rod 801, a spacing adjustment block 802 is installed, and a spacing adjustment fixed shaft 803 is inserted into the side of the spacing adjustment block 802. Through the mutual cooperation of the fourth connecting rod 801, the spacing adjustment block 802 and the spacing adjustment fixed shaft 803, the lateral spacing between the first connecting rod 1 and the third connecting rod 5 can be adjusted, so as to effectively improve the applicability of the device during use. In the default state, the device is as Figure 1 and Figure 2 shown. When the battery module and battery pack used are relatively long, the staff can first detach the first connecting rod 1 and the fifth connecting rod 10 from the side of the device through the spacing adjustment component 8, and add an appropriate number of second connecting rods 3, so as to meet the use requirements of longer modules or battery packs.
[0028] Working principle: When the present utility model is in use, the staff can first, according to the use requirements, push and pull the second connecting rod 3 to displace the second guide rail 4 forward and backward, thereby driving the first connecting rod 1 and the third connecting rod 5 to complete the forward and backward movement, and then the linkage of the visible number block component 7 can be completed. At this time, the number plate body 703 moves from the visible position of window A to the visible position of window B, so that the overall switching of the auxiliary wiring indication of two battery packs with the same core arrangement and different polarities can be completed, and there will be no problem that a single or multiple positions are not adjusted or adjusted incorrectly. After the overall switching, the wiring harness can be connected while observing the wiring serial number through the visible window, and the effect of synchronous operation of wiring and inspection can be achieved.
[0029] When different cores use the same structure and arrangement method, the position of the spacing adjustment block 802 in the spacing adjustment component 8 can be adjusted. After the adjustment is completed, the spacing adjustment fixed shaft 803 is inserted into the matching hole between the spacing adjustment block 802 and the fourth connecting rod 801, so that the spacing can be locked. When the number of cores in a single module or battery pack is greater than the current tooling matching number, splicing guide rails and splicing connecting rods with the same specifications can be added, and the corresponding components are connected by connecting pins 9, and the corresponding actions are completed through transmission to complete the situation adapted to the module. The above is the entire working principle of the present utility model.
[0030] In the present utility model, the installation methods, connection methods or setting methods of all the above-mentioned components are common mechanical methods, and the specific structures, models and coefficient indexes of all their components are their own technologies. As long as their beneficial effects can be achieved, they can be implemented, so no more details will be described.
[0031] The above embodiments are the preferred embodiments of the present utility model. However, the embodiments of the present utility model are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present utility model shall be equivalent replacement methods and are all included in the protection scope of the present utility model.
