Description

Technical Field

[0001] The present invention relates to the technical field of multi-battery energy storage battery assemblies, and specifically to a multi-battery energy storage battery assembly. Background Art

[0002] Multi-battery energy storage battery filling refers to the process of filling electrolyte into a battery pack composed of multiple batteries.

[0003] In the manufacturing process of multi-battery energy storage battery assemblies, automated filling technology has become an ideal choice for large-scale production due to its high efficiency and precision. Automated filling systems are usually equipped with high-precision filling heads that can precisely control the discharge volume of the electrolyte according to a preset program, completing the filling of a large number of battery assemblies per unit time and greatly improving production efficiency. However, this technology has significant drawbacks. On the one hand, the upfront investment cost of automated filling equipment is extremely high, requiring the purchase of professional filling machinery, complex control systems, and supporting sensor equipment, which is an unaffordable financial burden for small factories with limited funds and severely restricts the widespread application of this technology. On the other hand, the cleaning of automated filling heads is extremely cumbersome. Since the electrolyte is corrosive and has a complex composition, after a batch of filling is completed, the remaining electrolyte will adhere to the inner pipes and nozzle surfaces. If not cleaned thoroughly in a timely manner, it will not only cause cross-contamination between different batches of electrolyte, affecting the consistency of battery performance, but also block the nozzle due to the crystallization of the remaining electrolyte, resulting in a decline in subsequent filling accuracy and even equipment failure. Currently, the cleaning of automated filling heads usually requires shutting down the machine and relying on specialized cleaning equipment and complex procedures, consuming a large amount of time and manpower, further increasing production costs and equipment maintenance difficulties.

[0004] Based on the above description, there will be smaller factories for manual filling. Manual filling, as a traditional electrolyte filling method, is still widely used in small factories or production scenarios with low requirements for automation. Although manual operation has a lower cost in terms of equipment investment, there are still many problems that are difficult to overcome. When judging the liquid level height of electrolyte filling, manual operation mainly relies on visual observation and experience judgment, lacking precise quantitative standards. The visual errors and differences in experience levels of different operators result in uneven electrolyte liquid levels in each battery assembly. An overly high liquid level will cause the electrolyte to overflow during the charging and discharging process of the battery, corroding the battery casing and surrounding equipment and affecting the safety and service life of the battery. An overly low liquid level cannot meet the chemical reaction requirements inside the battery, resulting in a reduction in battery capacity and unstable performance. In addition, since it is difficult for manual operation to precisely control the filling flow rate and volume like automated equipment, during the docking, filling process, and detachment of the filling head and the battery assembly, even a slight oversight can cause electrolyte leakage and splashing, resulting in a deviation between the actual amount of electrolyte filled into the battery assembly and the expected amount, affecting the consistency and stability of product quality.

[0005] Therefore, it is urgent to develop an electrolyte filling technology that can effectively solve the above problems and balance cost - effectiveness, filling accuracy, and safety.

[0006] Therefore, the present invention proposes a multi - battery type battery assembly to solve the above problems. Summary of the Invention

[0007] In view of this, the technical problem to be solved by the present invention is to propose a multi - battery type battery assembly to solve the problems existing in the prior art.

[0008] To achieve the above object, the present invention provides the following technical solution: A multi - battery type battery assembly includes: a battery housing, a cover plate, a filling port, an auxiliary sealing plate, and a power connection post. The cover plate is fixedly connected to the battery housing by buckling. The filling ports are equidistantly arranged on the battery housing. The auxiliary sealing plate is slidably clamped on the battery housing. The power connection posts are symmetrically fixed on the battery housing. It further includes: a leak - proof filling and cleaning integrated component, and a liquid level height monitoring and feedback component. The liquid level height monitoring and feedback component is located below the leak - proof filling and cleaning integrated component; The leak - proof filling and cleaning integrated component is used for protecting against electrolyte leakage during filling and assisting subsequent cleaning and maintenance; The liquid level height monitoring and feedback component is used for feeding back the filling amount of the electrolyte.

[0009] Preferably, the leak - proof filling and cleaning integrated component includes a filling head above the filling port. A vertical column cavity is vertically penetrated through the filling head. A first filling pipe fitting is arranged in the vertical column cavity. Auxiliary sliding grooves are circumferentially opened on the first filling pipe fitting. The top of the first filling pipe fitting is rotatably connected to an external pipeline.

[0010] Preferably, a ring cavity is opened in the filling head. A driving wheel is fixedly connected in the ring cavity. A circular ring is rotatably connected in the ring cavity. The circular ring is fixedly connected to the first filling pipe fitting.

[0011] Preferably, a second filling pipe fitting is sleeved at the bottom of the first filling pipe fitting. A guiding groove is opened on the second filling pipe fitting. Symmetrically fixed connection sliding columns are arranged on the upper part of the second filling pipe fitting. The sliding columns are slidably connected in the auxiliary sliding grooves. Symmetrically fixed connection guiding columns are arranged at the bottom of the filling head.

[0012] Preferably, an inner auxiliary ring part is fixedly connected to the bottom end of the second filling pipe fitting.

[0013] Preferably, the liquid level height monitoring and feedback component includes a monitoring chamber opened in the second filling pipe fitting. A feedback ring is slidably connected in the monitoring chamber.

[0014] Preferably, vacuum column rods are symmetrically and fixedly connected to the bottom surface of the feedback loop. A hollow floating column is fixedly connected to the bottom of the vacuum column rod. A connecting rod is fixedly connected to the bottom end of the vacuum column rod. A metal block is fixedly connected to one end of the connecting rod.

[0015] Preferably, electromagnets are symmetrically and fixedly connected to the bottom surface of the filling head.

[0016] Compared with the prior art, the present invention provides a multi-battery type battery assembly, which has the following beneficial effects: 1. The present invention has the following advantages in electrolyte filling by adopting the first filling pipe fitting and the second filling pipe fitting in a telescopic mode: The telescopic pipe fitting can penetrate into the battery filling port, so that the electrolyte can be directly injected into the specified position, avoiding the loss of electrolyte caused by splashing or leakage, thereby ensuring that the actual filling amount is highly consistent with the discharge amount controlled by the program, improving the accuracy of the filling amount, and helping to ensure the consistency and stability of the battery performance; Improving the cleanliness of the production environment: Avoiding the splashing of electrolyte into the surrounding environment during filling, keeping the production equipment and the working area clean, reducing the risk of corrosion and damage of the equipment by the electrolyte, extending the service life of the equipment, reducing the maintenance frequency and cost of the equipment, effectively avoiding the splashing of electrolyte onto the operators, reducing the risk of operators coming into contact with the corrosive electrolyte, improving the safety of manual filling, and protecting the personal safety of the operators; The telescopic design can adapt to the filling ports of batteries with different specifications and shapes. Whether it is a small battery or a large battery assembly, good docking and filling can be achieved by adjusting the telescopic lengths of the first filling pipe fitting and the second filling pipe fitting, improving the versatility and adaptability of the filling equipment, and reducing the cost and time required for replacing different filling equipment due to different battery models.

[0017] 2. The filling head composed of the first filling pipe fitting and the second filling pipe fitting in the anti-leakage filling and cleaning integrated assembly of the present invention adopts a telescopic mode. In addition to reducing the risk of electrolyte splashing during filling, it also has the following advantages: Significantly improving the cleaning efficiency: When the traditional filling head is cleaned, due to its fixed structure, it is difficult to reach some corners and gaps with residual electrolyte and crystallization. A large amount of time is required for disassembly, soaking, and manual brushing during cleaning; The telescopic filling head composed of the first filling pipe fitting and the second filling pipe fitting has changed this situation. During cleaning, the pipe fittings can freely expand and contract, and the first filling pipe fitting can assist in cleaning the residue in the second filling pipe fitting, quickly flushing away stubborn crystallization and residual electrolyte, greatly shortening the cleaning time, enabling the equipment to be put into the next production batch faster, and improving the overall production efficiency; Deep cleaning ensures filling accuracy: If residual electrolyte and crystals are not thoroughly removed, they will gradually accumulate, causing the inner diameter of the filling head to become smaller and the surface to become rough, affecting the flow rate and flow stability of the electrolyte, and reducing filling accuracy. The retractable design enables comprehensive deep cleaning to prevent residues. This allows the electrolyte to be injected into the battery at a precise flow rate and volume during subsequent filling, ensuring that the electrolyte volume in each battery cell is consistent, and improving the performance uniformity and stability of multi-battery storage battery assemblies.

[0018] 3. The design of the liquid level height monitoring and feedback component in the present invention can bring the following benefits: Achieve precise filling control: Traditional manual filling relies on the experience of operators and visual observation, and there are also deviations in automated filling due to various factors, making it difficult to accurately control the electrolyte filling volume. The liquid level height monitoring and feedback component can measure the liquid level height of the electrolyte in the battery case in real time and accurately, and feed the data back to the filling system. Whether it is the program control of automated filling or the real-time reference during manual operation, the filling flow rate and volume can be adjusted in a timely manner based on the accurate liquid level information, ensuring that the electrolyte filling volume strictly meets the standards, eliminating battery performance differences caused by inaccurate filling volumes, and improving product consistency. Ensure the stability of battery performance and quality: An appropriate electrolyte filling volume is a key factor in the stable performance of the battery. Overfilling will cause the electrolyte to overflow, corroding the battery case and surrounding components, affecting the safety and lifespan of the battery; underfilling will cause insufficient chemical reactions inside the battery, reducing the battery capacity and performance. The liquid level height monitoring and feedback component monitors the filling process throughout, ensuring that each battery can obtain a precise and appropriate amount of electrolyte, guaranteeing the stability of battery performance from the source, reducing the defective rate, and improving the overall quality of the product. Improve production efficiency and reduce costs: By precisely controlling the filling volume, rework caused by overfilling or underfilling is avoided, reducing waste of raw materials and loss of production time, and improving production efficiency. For automated filling systems, the liquid level height monitoring and feedback component can optimize program control, making it operate more efficiently, reducing equipment idling and ineffective operations. At the same time, precise filling volume control reduces the waste of electrolyte and lowers the raw material procurement cost. Brief Description of the Drawings

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] The present invention will be further described in detail below according to the drawings and embodiments.

[0023] Embodiment: Please refer to Figures 1 to 4 as shown in To solve the problems mentioned in the technical solution, the embodiment of the present application provides a multi-battery type battery component, including: a battery housing 1, a cover plate 2, a filling port 3, an auxiliary sealing plate 4, and an electric connection post 5. The cover plate 2 is fixedly connected to the battery housing 1 by buckling. The filling ports 3 are equidistantly opened on the battery housing 1. The auxiliary sealing plate 4 is slidably clamped on the battery housing 1. The electric connection posts 5 are symmetrically fixed on the battery housing 1. It is characterized in that it further includes: a leakage-proof filling and cleaning integrated component 6, a liquid level height monitoring and feedback component 7. The liquid level height monitoring and feedback component 7 is located below the leakage-proof filling and cleaning integrated component 6; The leakage-proof filling and cleaning integrated component 6 is used for preventing electrolyte leakage during filling and assisting subsequent cleaning and maintenance; The anti-leakage filling and cleaning integrated component 6 includes a filling head 601 above the filling port 3. A vertical column cavity 602 is vertically penetrated through the filling head 601. A first filling pipe fitting 603 is arranged in the vertical column cavity 602. An auxiliary sliding groove 604 is circumferentially opened on the first filling pipe fitting 603. The top of the first filling pipe fitting 603 is rotatably connected to an external pipeline 605. A ring cavity 606 is opened in the filling head 601. A driving wheel 607 is fixedly connected in the ring cavity 606. A circular ring 608 is rotatably connected in the ring cavity 606. The circular ring 608 is fixedly connected to the first filling pipe fitting 603. A second filling pipe fitting 609 is sleeved at the bottom of the first filling pipe fitting 603. A guiding groove 610 is opened on the second filling pipe fitting 609. Symmetrically fixed connection sliding columns 611 are arranged on the upper part of the second filling pipe fitting 609. The sliding columns 611 are slidably connected in the auxiliary sliding groove 604. Symmetrically fixed connection guiding columns 612 are arranged at the bottom of the filling head 601. An inner auxiliary ring part 613 is fixedly connected to the bottom end of the second filling pipe fitting 609.

[0024] Among them: The auxiliary sealing plate 4 is used to seal the filling port 3 on the cover plate 2 after the electrolyte filling is completed.

[0025] The anti-leakage filling and cleaning integrated component 6 is used for preventing the leakage of electrolyte during filling and assisting subsequent cleaning and maintenance.

[0026] The filling head 601 is manually operated by a person or connected to an automated control equipment component.

[0027] The vertical column cavity 602 mainly provides spatial assistance for the movement of the first filling pipe fitting 603 and the second filling pipe fitting 609.

[0028] The auxiliary sliding groove 604 is similar to a W shape and is circumferentially opened on the first filling pipe fitting 603.

[0029] The bottom end of the external pipeline 605 has an inner ring piece, which is used to assist in clamping at the recessed part at the top of the first filling pipe fitting 603. In this way, after connection, the two can rotate relative to each other.

[0030] The driving wheel 607 is driven by a motor.

[0031] An annular groove is opened on the outer ring of the circular ring 608, and both the inner surface and the annular outer peripheral surface of the driving wheel 607 are rough.

[0032] The filling head 601, the first filling pipe fitting 603, and the second filling pipe fitting 609 are all made of a transparent corrosion-resistant material. In this design, it is implemented as glass.

[0033] The guiding groove 610 and the guiding column 612 are used in cooperation.

[0034] The inner auxiliary ring member 613 is used to extend into the filling port 3 during the filling of the electrolyte for blocking the filling port 3.

[0035] Further embodiments: Please refer to Figure 2 , Figures 4 to 6 as shown in: The liquid level height monitoring and feedback component 7 is used to feedback the filling amount of the electrolyte. The liquid level height monitoring and feedback component 7 includes a monitoring chamber 701 opened in the second filling pipe fitting 609. A feedback ring 702 is slidably connected in the monitoring chamber 701. Vacuum column rods 703 are symmetrically and fixedly connected to the bottom surface of the feedback ring 702. A hollow floating column 704 is fixedly connected to the bottom of the vacuum column rods 703. A connecting rod 705 is fixedly connected to the bottom end of the vacuum column rods 703. A metal block 706 is fixedly connected to one end of the connecting rod 705. Electromagnets 707 are symmetrically and fixedly connected to the bottom surface of the filling head 601.

[0036] Among them: The liquid level height monitoring and feedback component 7 is used to feedback the filling amount of the electrolyte.

[0037] The feedback ring 702 moves in the monitoring chamber 701, so that the filling solution amount can be indirectly feedback by observing the moving position during manual filling; when used on automated equipment, it can be used in cooperation with an infrared sensor, that is, the feedback ring 702 can be used as a blocking medium during the infrared reflection process during movement, so as to cooperate to achieve electrical signal feedback.

[0038] Both the vacuum column rods 703 and the hollow floating column 704 are hollow inside. In addition to reducing the weight of the components, they can also be used as floats.

[0039] The surface of the metal block 706 is coated with a corrosion-resistant layer.

[0040] The working principle of all the contents in the above embodiments is as follows: In the initial state: The inner auxiliary ring member 613 is attached to the filling head 601. The second filling pipe fitting 609 does not extend from the filling head 601. The electromagnet 707 performs an adsorption action on the metal block 706.

[0041] The following is the working process of the anti-leakage filling and cleaning integrated component 6: During use, the filling head 601 is transferred above the filling port 3 opened on the battery case 1 manually or by an automated component. Then, an electric motor that controls the driving wheel 607 externally drives the driving wheel 607 to rotate. During rotation, the driving wheel 607 causes the annular ring 608 to drive the fixedly connected first filling pipe fitting 603 to rotate under the action of friction with the surface of the annular ring 608. During this process, the annular cavity 606 plays an auxiliary role. Further, during the rotation of the first filling pipe fitting 603, since the sliding column 611 on the second filling pipe fitting 609 is slidably connected to the W-shaped auxiliary sliding groove 604 opened on the first filling pipe fitting 603, at this time, the second filling pipe fitting 609 will drive the internally assisted ring member 613 fixedly connected to the bottom end to gradually approach the filling port 3 and enter the battery case 1; further, at this time, the electrolyte filling work can be carried out through the external pipeline 605 and the assistance of the first filling pipe fitting 603, the second filling pipe fitting 609, and the internally assisted ring member 613. Furthermore, the use of the retractable first filling pipe fitting 603 and second filling pipe fitting 609 has the following advantages during electrolyte filling: The retractable pipe fitting can penetrate into the battery filling port 3, enabling the electrolyte to be directly injected into the designated position, avoiding electrolyte loss caused by splashing or leakage, thereby ensuring that the actual filling volume is highly consistent with the discharged volume controlled by the program, improving the accuracy of the filling volume, and helping to ensure the consistency and stability of the battery performance. Improve the cleanliness of the production environment: Avoid the electrolyte splashing into the surrounding environment during filling, keep the production equipment and the working area clean, reduce the risk of corrosion and damage of the equipment by the electrolyte, extend the service life of the equipment, reduce the maintenance frequency and cost of the equipment, effectively avoid the electrolyte splashing onto the operator, reduce the risk of the operator coming into contact with the corrosive electrolyte, improve the safety of manual filling, and protect the personal safety of the operator. The retractable design can adapt to the filling ports 3 of batteries with different specifications and shapes. Whether it is a small battery or a large battery assembly, good docking and filling can be achieved by adjusting the retractable lengths of the first filling pipe fitting 603 and the second filling pipe fitting 609, improving the versatility and adaptability of the filling equipment, and reducing the cost and time required to replace different filling equipment due to different battery models.

[0042] Furthermore, the perfusion head composed of the first filling pipe fitting 603 and the second filling pipe fitting 609 in the anti-leakage filling and cleaning integrated component 6 adopts a telescopic mode. In addition to reducing the risk of electrolyte splash during filling, it can significantly improve the cleaning efficiency. When the traditional perfusion head is cleaned, due to its fixed structure, it is difficult to reach some corners and crevices with residual electrolyte and crystallization, and a lot of time is required for disassembly, soaking and manual brushing during cleaning. The telescopic perfusion head composed of the first filling pipe fitting 603 and the second filling pipe fitting 609 has changed this situation. During cleaning, the pipe fittings can freely expand and contract, and the first filling pipe fitting 603 can assist in cleaning the residues in the second filling pipe fitting 609, quickly flushing away stubborn crystallization and residual electrolyte, greatly shortening the cleaning time, enabling the equipment to be put into the next production batch faster, and improving the overall production efficiency; Deep cleaning ensures filling accuracy: If the residual electrolyte and crystallization are not completely removed, they will gradually accumulate, resulting in a smaller inner diameter and rougher surface of the perfusion head, affecting the stability of the electrolyte flow rate and flow volume, and reducing the filling accuracy. The telescopic design enables comprehensive and deep cleaning, eliminating residues. This allows the electrolyte to be injected into the battery at a precise flow rate and flow volume during subsequent filling, ensuring that the electrolyte volume in each battery unit is consistent, and improving the performance uniformity and stability of the multi-battery battery assembly.

[0043] Please refer to the above working process Figures 1 to 4 。

[0044] The following is the working process of the liquid level height monitoring and feedback component 7: Furthermore, when the inner auxiliary ring 613 enters the battery housing 1 through the filling port 3, at this time, the electromagnet 707 releases the magnetic attraction on the metal block 706. At this time, the metal block 706 will drive the feedback ring 702 on it to move downward through the connecting rod 705, the hollow floating column 704, and the metal block 706. Initially, the feedback ring 702 will be located at the bottom of the monitoring chamber 701. Further, with the filling of the electrolyte, the rising liquid level of the electrolyte will cause the vacuum column rod 703 and the hollow floating column 704 on the vacuum column rod 703 to float upward. At this time, the feedback ring 702 at the upper end of the vacuum column rod 703 will move upward in the monitoring chamber 701, thereby feeding back the change in the electrolyte liquid level during the filling process; Furthermore, the design of the liquid level height monitoring and feedback component 7 can bring the following benefits: achieving precise filling control: Traditional manual filling relies on the experience of operators and visual observation. Automated filling also has deviations due to various factors and it is difficult to accurately control the electrolyte filling volume. The liquid level height monitoring and feedback component 7 can measure the liquid level height of the electrolyte in the battery housing 1 in real time and accurately, and feed the data back to the filling system. Whether it is the program control of automated filling or the real-time reference during manual operation, the filling flow rate and volume can be adjusted in a timely manner based on the accurate liquid level information to ensure that the electrolyte filling volume strictly meets the standards, eliminate the battery performance differences caused by inaccurate filling volume, and improve product consistency; Ensuring the stability of battery performance and quality: An appropriate electrolyte filling volume is a key factor for the stability of battery performance. Overfilling will cause the electrolyte to overflow, corrode the battery housing and surrounding components, and affect the safety and lifespan of the battery; underfilling will make the internal chemical reaction of the battery insufficient, reducing the battery capacity and performance. The liquid level height monitoring and feedback component 7 monitors the filling process throughout, ensuring that each battery can obtain a precise and appropriate amount of electrolyte, guaranteeing the stability of battery performance from the source, reducing the defective rate, and improving the overall quality of the product; Improving production efficiency and reducing costs: By precisely controlling the filling volume, rework caused by overfilling or underfilling is avoided, reducing raw material waste and production time loss, and improving production efficiency. For the automated filling system, the liquid level height monitoring and feedback component 7 can optimize the program control to make it operate more efficiently, reducing equipment idling and ineffective operations. At the same time, the precise filling volume control reduces the waste of electrolyte and lowers the raw material procurement cost.
