Description

Technical Field

[0001] This invention relates to the field of power storage technology, specifically to a modular energy storage system with controlled heat dissipation. Background Technology

[0002] With the rapid development of energy storage technology, modular energy storage systems have been widely used in grid regulation, renewable energy grid integration, and electric vehicle charging. Especially in the renewable energy sector, due to intermittency and instability, energy storage systems are needed for energy storage and regulation, and modular energy storage systems can better meet this need.

[0003] Furthermore, modular energy storage systems require a cooling system to ensure that each individual battery module can be effectively cooled. However, the cooling system in conventional energy storage devices operates continuously and stably. When there are fewer battery modules installed in a modular energy storage device, some of the delivered cooling airflow will still enter the frame of the module without batteries, resulting in insufficient utilization of the cooling airflow. On the other hand, in large modular energy storage systems, some individual battery modules are installed at a high height, which greatly increases the difficulty of installation and retrieval. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a modular controlled heat dissipation energy storage system to solve the problems mentioned in the background. The present invention can automatically direct the cooling airflow according to the number of independent energy storage frames, and further ensure that the cooling airflow is only applied to the area where the independent battery modules are installed, thereby improving the utilization rate of low-temperature airflow, and making the disassembly and assembly of independent battery modules more labor-saving and convenient.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a modular energy storage system with controlled heat dissipation, comprising an independent energy storage frame, a cooling system, module support components, and independent battery modules.

A support shaft is inserted through the bottom of the support plate, and both ends of the support shaft are welded and fixed to the inner wall of the independent energy storage frame. The side of the support plate is in contact with the inner wall of the independent energy storage frame. An integrally formed plug-in plate is formed at the rear bottom of each independent energy storage frame, and the plug-in plate is embedded inside the cooling system.

[0006] Furthermore, the module support component includes a tray, a slide plate, and a front baffle. The rear side of the tray is integrally formed with an arc-shaped plate, the top of the arc-shaped plate is provided with a first docking hole, the surface of the tray is provided with a sliding groove, the sliding plate is embedded in the sliding groove, and a heat-conducting plate is embedded in the surface of the tray.

[0007] Furthermore, the rear end of the skateboard is integrally formed with a rear baffle, a first spring is welded to the rear end of the skateboard, a heat dissipation fin groove is opened inside the support plate, a guide rod is welded to the rear end of the front baffle, and the end of the guide rod is embedded in the interior of the support plate.

[0008] Furthermore, the bottom of the tray is integrally formed with a rotating sleeve, which is sleeved on the surface of the support shaft. A handle is welded to the surface of the front baffle, and an exhaust hole is opened at the bottom of the front baffle. The end of the first spring is welded and fixed to the inner wall end of the slide groove, and the exhaust hole is aligned with the opening position of the heat dissipation fin groove.

[0009] Furthermore, the independent energy storage frame includes a side plate and a plug-in plate. The bottom of the side plate is integrally formed with a base. The front end of the base is provided with a locking screw hole. The rear end of the base is integrally formed with a plug-in plate. The top of the plug-in plate is provided with a connecting notch.

[0010] Furthermore, the rear end of the independent energy storage frame is provided with a flow channel, and the inner wall of the side plate is provided with a second docking hole, and the flow channel is partially connected to each second docking hole. The arc plate is used to cover the surface of the second docking hole, and the arc plate rotates around the support shaft to align and connect the first docking hole and the second docking hole with each other.

[0011] Furthermore, the cooling system includes a conveying channel and a cooling airflow pipe. The end of the cooling airflow pipe is connected to an external refrigeration device. A guide groove is provided inside the conveying channel, and the other end of the cooling airflow pipe is connected to the inside of the guide groove.

[0012] Furthermore, a diversion groove is provided at the bottom of the flow guide groove, an expansion groove is provided on the inner wall of the diversion groove, and a sealing plate is inserted at the bottom of the diversion groove.

[0013] Furthermore, the front end of the sealing plate is integrally formed with a pressure plate, and the rear end of the pressure plate is welded with a second spring.

The locking screw is used to insert into the interior of the locking screw hole.

[0015] The beneficial effects of this invention are:

[0016] 1. This modular energy storage system with controlled heat dissipation uses a loading and unloading unit to push each independent energy storage frame and control whether it connects with the cooling system behind it. Therefore, this structure can automatically guide the cooling airflow according to the number of independent energy storage frames, so that the cooling airflow can all enter the independent energy storage frames in use. Moreover, the process of inserting and removing the independent energy storage frames is more labor-saving and efficient.

[0017] 2. In this modular controlled heat dissipation energy storage system, modular support components are used to support each independent battery module. The support components with independent battery modules are automatically connected to the internal flow channel behind the independent energy storage frame. Therefore, it can further ensure that the cooling airflow is only applied to the area where the independent battery module is installed, thus improving the utilization rate of low-temperature airflow.

[0018] 3. The modular energy storage system with controlled heat dissipation features independent battery modules supported by module support components. After placement, the module support components tilt backward, ensuring that the placed independent batteries will not easily fall off without the need for locking. Furthermore, when disassembling or assembling the placed independent battery modules, the module support components can be pulled to assist in the operation, allowing heavier independent battery modules to slide from a higher position to a lower position before being removed, making the disassembly and assembly process of the independent battery modules more labor-saving and convenient.

[0027] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0028] Please see Figures 1 to 7 The present invention provides the following technical solution: a modular controlled heat dissipation energy storage system, the energy storage system including an independent energy storage frame 1, a cooling system 2, a module support assembly 3 and an independent battery module 9, a hydraulic rod 27 screwed to the side of the cooling system 2, and a loading and unloading unit 4 installed at the end of the hydraulic rod 27, the cooling system 2 docking with multiple independent energy storage frames 1 at the same time, and multiple module support assemblies 3 are embedded inside each independent energy storage frame 1, the independent battery module 9 is placed on the surface of the module support assembly 3, and a support plate 10 is installed at the bottom of the module support assembly 3, a support shaft 18 is inserted through the bottom of the support plate 10, both ends of the support shaft 18 are welded and fixed to the inner wall of the independent energy storage frame 1, the side of the support plate 10 is in contact with the inner wall of the independent energy storage frame 1, and an insert plate 7 is integrally formed at the bottom rear end of each independent energy storage frame 1, the insert plate 7 being embedded inside the cooling system 2. The modular energy storage system with controlled heat dissipation stores and utilizes the delivered electrical energy through multiple independent battery modules 9. During the energy storage process, the cooling system 2 built behind it provides more targeted cooling treatment for the modular battery structure in a sustainable manner.

[0029] During the assembly of this invention, each independent battery module 9 is directly placed into the module support component 3, and then each independent battery module 9 is placed into the independent energy storage frame 1. Finally, the assembled independent energy storage frame 1 is pushed towards the rear end with the help of the loading and unloading unit 4 until the independent energy storage frame 1 is connected to the rear cooling system 2. The low-temperature airflow delivered by the cooling system 2 can then enter the connected independent energy storage frame 1. After the independent battery module 9 is placed, the module support component 3 inside each independent energy storage frame 1 will automatically control the rear arc plate 15 to rotate, ensuring that the module support component 3 can communicate with the cold airflow entering from the rear of the independent energy storage frame 1. This allows the low-temperature airflow to directly enter the module support component 3 containing the independent battery module 9, thereby achieving close-range targeted cooling of each stored independent battery module 9.

[0030] In this embodiment, the module support assembly 3 includes a tray 10, a slide plate 22, and a front baffle 11. An arc-shaped plate 15 is integrally formed on the rear side of the tray 10, and a first mating hole 16 is formed at the top of the arc-shaped plate 15. A sliding groove 20 is formed on the surface of the tray 10, and the slide plate 22 is embedded inside the sliding groove 20. A rear baffle 14 is integrally formed on the top rear end of the slide plate 22, and a first spring 21 is welded to the rear end of the slide plate 22. A heat dissipation fin groove 23 is formed inside the tray 10, and a guide rod 24 is welded to the rear end of the front baffle 11, with the end of the guide rod 24 embedded inside the tray 10. The bottom of the support plate 10 is integrally formed with a rotating sleeve 17, which is sleeved on the surface of the support shaft 18. A handle 12 is welded to the surface of the front baffle 11, and an exhaust hole 13 is opened at the bottom of the front baffle 11. The end of the first spring 21 is welded and fixed to the end of the inner wall of the slide groove 20. The exhaust hole 13 is aligned with the opening of the heat dissipation fin groove 23. The independent battery module 9 is supported by the module support component 3, and the module support component 3 tilts backward after placement, ensuring that the placed independent battery will not fall easily without locking. When disassembling or assembling the placed independent battery module 9, the module support component 3 can be pulled to assist the operation, allowing the heavier independent battery module 9 to slide from a high place to a low place before being taken out, making the disassembly and assembly process of the independent battery module 9 more labor-saving and convenient.

[0031] Specifically, when installing the independent battery module 9, first manually pull out the front baffle 11 of the module support assembly 3. Since the front baffle 11 is heavier without the independent battery module 9, the front end of the module support assembly 3 is heavier than the rear end. The front end of the module support assembly 3 is in a downward-pressed state, and the rear end is in a tilted state. After pulling out the front baffle 11, it will tilt downwards. Figure 2As shown, the independent battery module 9 is placed on the module support assembly 3, and the handle 12 is manually pushed. With the help of the pulling force of the first spring 21, the placed independent battery module 9 is pushed onto the tray 10. Then, the module support assembly 3 is manually embedded into the independent energy storage frame 1 to complete the placement of the independent battery module 9. Since the independent battery module 9 is placed and the support shaft 18 is located below the tray 10 near the front end, the influence of the weight of the front baffle 11 is reduced. The center of gravity of the module support assembly 3 shifts backward, which ultimately causes the rear end of the entire module support assembly 3 to press down and the front end to lift up.

[0032] In this embodiment, the independent energy storage frame 1 includes a side plate 5 and a plug-in plate 7. A base 6 is integrally formed at the bottom of the side plate 5. A locking screw hole 8 is formed at the front end of the base 6, and a plug-in plate 7 is integrally formed at the rear end of the base 6. A connecting notch 37 is formed at the top of the plug-in plate 7. A flow channel 38 is formed at the rear end of the independent energy storage frame 1. A second docking hole 39 is formed on the inner wall of the side plate 5, and the flow channel 38 is partially connected to each of the second docking holes 39. An arc-shaped plate 15 is used to cover the surface of the second docking holes 39. After rotating around the support shaft 18, the arc-shaped plate 15 aligns and connects the first docking hole 16 and the second docking hole 39. Each independent battery module 9 is supported by a module support assembly 3, and the support assembly with the independent battery module 9 placed on it automatically opens to communicate with the interior of the flow channel 38 at the rear of the independent energy storage frame 1. Therefore, it can further ensure that the cooling airflow is only applied to the area where the independent battery module 9 is installed, improving the utilization rate of the low-temperature airflow.

[0033] Specifically, when the independent energy storage frame 1 is pushed toward the rear end by the loading and unloading unit 4, the plug plate 7 will be pressed against the pressure plate 31. The pressure plate 31 moves backward, causing the top sealing plate 32 to move away from the inside of the diversion groove 36. The sealing plate 32 is then embedded into the inside of the expansion groove 35. At this time, the diversion groove 36 can be connected to the inside of the plug plate 7 through the connecting notch 37. Therefore, the low-temperature airflow flowing inside the guide groove 34 can enter each second docking hole 39 along the connecting notch 37 and the guide channel 38. In the area of ​​the delivery channel 25 where the independent energy storage frame 1 is not plugged in, the pressure plate 31 is not under pressure. Therefore, the sealing plate 32 will always block the diversion groove 36 in this area, ensuring that the low-temperature airflow can flow into the independent energy storage frame 1 in the above-mentioned usage state.

[0034] After each module support component 3 has an independent battery module 9 placed in it, the rear end will move downwards. As a result, the arc plate 15 will move away from the surface of the second docking hole 39, and finally align the first docking hole 16 with the second docking hole 39. Therefore, the low-temperature airflow inside the flow channel 38 can enter the interior of the heat sink fin slot 23 along the first docking hole 16 and the second docking hole 39, and finally be discharged outwards from the interior of the exhaust hole 13 at the front end. However, the module support component 3 without an independent battery module 9 will have its rear end tilted up, so the arc plate 15 will close the second docking hole 39, and the low-temperature airflow will not enter the unused module support component 3.

[0035] In this embodiment, the cooling system 2 includes a conveying channel 25 and a cooling airflow pipe 26. The end of the cooling airflow pipe 26 is connected to an external refrigeration device. A guide groove 34 is formed inside the conveying channel 25, and the other end of the cooling airflow pipe 26 is connected to the inside of the guide groove 34. A diversion groove 36 is formed at the bottom of the guide groove 34, and a telescopic groove 35 is formed on the inner wall of the diversion groove 36. A sealing plate 32 is inserted into the bottom of the diversion groove 36. A pressure plate 31 is integrally formed at the front end of the sealing plate 32, and a second spring 33 is welded to the rear end of the pressure plate 31. The rear end of the second spring 33 is fixedly connected to the inner wall of the diversion groove 36. The rear end of the sealing plate 32 is embedded in the telescopic groove 35. The surface of the pressure plate 31 is flush with the surface of the conveying channel 25, and the length of the pressure plate 31 is the same as the width of the independent energy storage frame 1. The loading and unloading unit 4 includes a hydraulic rod 27 and a transmission plate 28. The two ends of the hydraulic rod 27 are fixedly connected to the conveying channel 25 and the surface of the transmission plate 28 respectively by screws. Multiple locking screws 29 are inserted through the middle of the transmission plate 28. A handwheel 30 is welded to one end of each locking screw 29, which is used to insert into the locking screw hole 8. The loading and unloading unit 4 pushes each independent energy storage frame 1 and controls whether it connects with the subsequent cooling system 2. Therefore, this structure can automatically guide the cooling airflow according to the number of independent energy storage frames 1, ensuring that all cooling airflow enters the independent energy storage frames 1 in use. Furthermore, the insertion and removal process of the independent energy storage frames 1 is more labor-saving and efficient.

[0036] Specifically, after turning the handwheel 30 to insert the locking screw 29 into the locking screw hole 8, the hydraulic rod 27 is controlled to extend and retract in this state, which can synchronously drive the independent energy storage frame 1 after locking to move horizontally. This allows control over whether the independent energy storage frame 1 inserts the rear plug plate 7 into the conveying channel 25, and thus directly controls the area of ​​the independent energy storage frame 1 that the low-temperature airflow delivered in the cooling system 2 can enter.

[0037] The foregoing has shown and described the basic principles and main features of the present invention and its advantages. It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
