Description

Technical Field

[0001] This utility model relates to the field of energy storage equipment technology, and in particular to a modular supercapacitor module for energy storage. Background Technology

[0002] Supercapacitors are a new type of energy storage device that falls between traditional capacitors and rechargeable batteries. They store energy through a double-layer interface formed between electrodes and electrolytes. They offer advantages such as large capacity, wide operating temperature range, long service life, and no environmental pollution, leading to their widespread use. To meet the high-capacity requirements of power supercapacitor energy storage devices, each supercapacitor energy storage system typically consists of several identical supercapacitor energy storage modules. To address the different technical parameters required by various energy storage systems, fixed-specification supercapacitor modules are usually used for construction. While these modules can be connected in series and parallel to create supercapacitor energy storage systems with different technical parameters, the system specifications are limited, making it difficult to meet the requirements of various energy storage systems, especially those with specific technical parameter requirements. Therefore, in scenarios requiring specific energy storage needs, supercapacitor modules usually need to be redesigned. Redesigning supercapacitor modules suffers from drawbacks such as long system development cycles, high costs, and difficulty in quickly responding to changes in system requirements.

[0032] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0033] Please combine Figure 1-6 This utility model discloses a modular supercapacitor module for energy storage. The supercapacitor module includes a housing 100, an energy storage unit 200 housed within the housing 100, and an output unit electrically connected to the energy storage unit 200. A control circuit board 110 is fixed to an inner side wall of the housing 100. A positive electrode protective sleeve 120 and a negative electrode protective sleeve 130, as well as a control interface 140 electrically connected to the control circuit board 110, are provided on the outer side wall of the housing 100 on the side where the control circuit board 110 is located. The positive electrode protective sleeve 120 and the negative electrode protective sleeve 130 are both made of plastic material and are used to protect the positive and negative electrodes of the modular supercapacitor module, thereby improving the safety of the modular supercapacitor module. The control interface 140 is used to connect to terminals to connect the supercapacitor module to external control equipment for monitoring the operation of the supercapacitor module.

[0034] Please combine further Figure 1-13The energy storage unit 200 includes at least one spliced ​​energy storage module, which serves as the basic energy storage and splicing unit of the supercapacitor module in this embodiment. The number of spliced ​​energy storage modules can be configured according to actual needs, and other external structures can be quickly modified accordingly. The example listed in this embodiment is a supercapacitor module composed of 12 spliced ​​energy storage modules, but this number is not limited in practical applications. Specifically, the spliced ​​energy storage module includes a support component, an energy storage component, and a conductive component. The support component includes two insulating protective sleeves 210 arranged vertically opposite each other. The two insulating protective sleeves 210 are actually symmetrically arranged with the horizontal plane as the symmetry point, forming an energy storage space between them. This energy storage space is used to house the energy storage component, and the conductive component is disposed outside the energy storage space. The insulating protective sleeve 210 has a mounting surface located within the energy storage space and a supporting surface facing away from the energy storage space. Multiple slots 211 are spaced apart within the mounting surface. Each slot 211 has a through hole 212 penetrating the supporting surface on its bottom surface. Multiple supporting feet 213 are spaced apart on the supporting surface, abutting against the inner wall of the outer casing 100. A slot 214 is provided in the area between each pair of adjacent through holes 212 on the supporting surface. Preferably, the slot 214 is a non-circular groove, or the slot 214 includes multiple grooves spaced apart. In this embodiment, by providing supporting feet 213 on the supporting surface of the insulating protective sleeve 210, while achieving a limiting fit between the outer casing 100 and the energy storage unit 200, the distance between the supporting surface and the inner surface of the outer casing 100 is extended, leaving a space between the supporting surface and the inner surface of the outer casing 100 to provide an installation area for conductive components. The insulating protective sleeve 210 has grooves 215 and protrusions 216 spaced apart on its annular sidewalls. When the number of energy storage modules spliced ​​in the energy storage unit 200 is greater than one, the protrusions 216 on the insulating protective sleeve 210 can be inserted into the grooves 215 of adjacent insulating protective sleeves 210. In other words, when multiple spliced ​​energy storage modules need to be assembled, it is only necessary to insert the grooves 215 on the insulating protective sleeve 210 into the protrusions 216 on its adjacent insulating protective sleeve 210 to achieve a detachable connection between the two insulating protective sleeves 210, which reduces the assembly difficulty of multiple spliced ​​energy storage modules in the energy storage unit 200.

[0035] The energy storage module includes multiple supercapacitor cells 220 housed within an energy storage space. The bottom of each supercapacitor cell 220 is inserted into a corresponding slot 211 of the insulating protective sleeve 210 at the bottom of the adjacent outer casing 100, and the top of each supercapacitor cell 220 is inserted into a corresponding slot 211 of the insulating protective sleeve 210 at the top of the adjacent outer casing 100. During actual installation, adjacent supercapacitor cells 220 within the same spliced ​​energy storage module can be arranged in the same or opposite directions as needed. In this embodiment, one end of each supercapacitor cell 220 is a positive electrode and the other end is a negative electrode. By inserting the two ends of the supercapacitor into the slots 211 of the two insulating protective sleeves 210 respectively, the supercapacitor cell 220 is positioned by the squeezing of the insulating protective sleeves 210 by the outer shell 100. At the same time, the insulating protective sleeves 210 can provide insulation protection for the supercapacitor cell 220. The positive and negative electrodes of the supercapacitor cell 220 correspond to the through holes 212 on the insulating protective sleeves 210 respectively, so as to provide the wiring part for the supercapacitor cell 220 to be electrically connected to the conductive components. When adjacent supercapacitor cells 220 are arranged in opposite directions (i.e., when one supercapacitor cell 220 is arranged facing forward (with its positive terminal at the top), the adjacent supercapacitor cells 220 are arranged in opposite directions (with their positive terminals at the bottom). Thus, when the supercapacitor cells 220 are connected via conductive components, they can be connected in series. Conversely, when adjacent supercapacitor cells 220 are arranged in the same direction (i.e., when one supercapacitor cell 220 is arranged facing forward, the adjacent supercapacitor cells 220 are also arranged facing forward; when one supercapacitor cell 220 is arranged in opposite directions, the adjacent supercapacitor cells 220 are also arranged in opposite directions), they can be connected in parallel. Correspondingly, when the number of spliced ​​energy storage modules is greater than one, adjacent spliced ​​energy storage modules can be arranged in either the forward or reverse direction to achieve parallel or series connection.

[0036] The conductive component includes two conductive mechanisms, each corresponding to one side of the support surface of the two insulating protective sleeves 210. Specifically, each of the two insulating protective sleeves 210 constituting the same energy storage module has one conductive mechanism. Each conductive mechanism includes multiple first conductive sheets 230 and a conductive wire harness 240. The middle of each first conductive sheet 230 has a protrusion 231 that corresponds to a slot 214, and the first conductive sheet 230 is electrically connected to two supercapacitor cells 220 on both sides of the slot 214. Through the cooperation of the protrusion 231 on the first conductive sheet 230 with the slot 214 on the support surface, pre-positioning of the first conductive sheet 230 can be achieved, so that both ends of the first conductive sheet 230 can be aligned with the two supercapacitor cells 220 on both sides of the slot 214, thereby reducing the difficulty of connecting the first conductive sheet 230 to the supercapacitor cells 220. In this embodiment, both ends of the first conductive sheet 230 pass through through holes 212 and are electrically connected to the supercapacitor cells 220. The conductive wire harness 240 includes multiple wires corresponding one-to-one with each of the first conductive plates 230. Each wire is electrically connected to two supercapacitor cells 220 connected to the same first conductive plate 230, and each wire is electrically connected to the control circuit board 110. Furthermore, the conductive wire harness 240 also includes a protective tube, in which each wire is housed for protection. When the number of energy storage modules in the energy storage unit 200 is greater than one, and multiple energy storage modules are arranged in a row and assembled, the protective tubes of the conductive wire harnesses 240 on each row of energy storage modules are the same. When the energy storage unit 200 includes multiple rows of assembled energy storage modules, the wires of the same row of energy storage modules are encapsulated and protected by the same protective tube.

[0037] The output unit includes two second conductive plates 300, which are used to provide the output terminals of the supercapacitor module in this solution. Specifically, one second conductive plate serves as the positive terminal of the supercapacitor module output, and the other second conductive plate serves as the negative terminal of the supercapacitor module output. In this embodiment, one second conductive plate 300 is electrically connected to the supercapacitor cell 220, which serves as the positive terminal of the energy storage unit 200, and is inserted into the positive terminal protective sleeve 120. The other second conductive plate 300 is electrically connected to the supercapacitor cell 220, which serves as the negative terminal of the energy storage unit 200, and is inserted into the negative terminal protective sleeve. Since each end of the spliced ​​energy storage module is provided with a conductive mechanism, the current conduction inside the supercapacitor module can be realized through the electrical connection between the first conductive plate on each of the two conductive mechanisms and the supercapacitor cell, as well as the electrical connection between the second conductive plate and the supercapacitor cell. When the energy storage unit 200 has only one spliced ​​energy storage module, there must be one supercapacitor cell 220 in the spliced ​​energy storage module used as the positive electrode of the energy storage unit 200, and there must be one supercapacitor cell 220 in the spliced ​​energy storage module used as the negative electrode of the energy storage unit 200; when the energy storage unit 200 includes multiple spliced ​​energy storage modules, the two supercapacitor cells 220 used as the positive and negative electrodes of the energy storage unit 200 can be located in the same spliced ​​energy storage module, or they can be located in two separate spliced ​​energy storage modules.

[0038] The outer casing 100 is used to house and fix the energy storage unit 200 and the output unit, thereby protecting the energy storage unit 200 and the output unit. In one embodiment, the outer casing 100 includes an upper support plate 150 located above the energy storage space, a lower support plate 160 located below the energy storage space, side support plates 170 located on the left and right sides of the energy storage space, a front panel 180 located in front of the energy storage space, and a rear support plate 190 located behind the energy storage space. The lower surface of the upper support plate 150 abuts against the support foot 213 of the insulating protective sleeve 210 at the top of the energy storage space, and the upper surface of the lower support plate 160 abuts against the support foot 213 of the insulating protective sleeve 210 at the bottom of the energy storage space. The side support plates 170, the front panel 180, and the rear support plate 190 are all screwed to the upper support plate 150 and the lower support plate 160. The control circuit board 110 is fixed on the front panel 180 facing the energy storage space. The positive electrode protective sleeve 120, the negative electrode protective sleeve 130, and the control interface 140 are disposed on the front panel 180 facing away from the energy storage space. Preferably, in this embodiment, the side support plate 170 and the rear support plate 190 are provided with openings, or the side support plate 170 and the rear support plate 190 are both composed of multiple vertical plates spaced apart. In this way, while connecting the upper support plate 150 and the lower support plate 160 through the side support plate 170 and the rear support plate 190, the internal space of the outer shell 100 is connected to the environment, which is conducive to the heat dissipation of the supercapacitor module.

[0039] Furthermore, a through hole 181 is formed on each side of the control circuit board 110 on the front panel 180. The positive electrode protective sleeve 120 and the negative electrode protective sleeve 130 are connected to the two through holes 181 respectively. The first conductive sheet 230 passes through the through hole 181 and is inserted into the positive electrode protective sleeve 120 or the negative electrode protective sleeve 130. In this embodiment, the positive electrode protective sleeve 120 has a first connection hole communicating with its inner cavity, and the negative electrode protective sleeve 130 has a second connection hole communicating with its inner cavity. Thus, when the supercapacitor module is connected to an external electrical device, the power terminal of the electrical device can pass through the first connection hole or the second connection hole and be electrically connected to the first conductive sheet 230. In addition, in this embodiment, two handles 182 are provided opposite each other on the side of the front panel 180 facing away from the energy storage space. The positive electrode protective sleeve 120 and the negative electrode protective sleeve 130 are located between the two handles 182. The handles 182 are used to provide a gripping part for the supercapacitor module, so as to move or transport the supercapacitor module. In this embodiment, the upper support plate 150, lower support plate 160, side support plate 170, rear support plate 190, front panel 180, and handle 182 are all made of metal materials, such as aluminum alloy or stainless steel, to ensure the structural strength of the entire supercapacitor module. Furthermore, insulating plates are provided between the upper support plate 150 and the insulating protective sleeve 210, and between the lower support plate 160 and the insulating protective sleeve 210, to prevent the upper support plate 150 or / and the lower support plate 160 from becoming electrified due to loose or disconnected internal wiring of the supercapacitor module, thereby improving the safety of the supercapacitor module.

[0040] To facilitate the assembly of multiple spliced ​​energy storage modules, in one embodiment, the insulating protective sleeve 210 has a centrally symmetrical structure, so that each insulating protective sleeve 210 can be spliced ​​with the others. Preferably, in this embodiment, the insulating protective sleeve 210 has a rectangular cross-section and is made of plastic material, such as PC or PVC. The insulating protective sleeve 210 includes four outer surfaces, each of which has a groove 215 and a protrusion 216. Thus, when the protrusion 216 of the insulating protective sleeve 210 is inserted into the groove 215 of an adjacent insulating protective sleeve 210, the protrusion 216 of the adjacent insulating protective sleeve 210 is simultaneously inserted into the groove 215 of that insulating protective sleeve 210. Furthermore, the groove 215 is a T-shaped groove, and the outer contour shape of the protrusion 216 is adapted to the inner contour shape of the groove 215. Thus, adjacent insulating sleeves 210 are inserted along the height direction of the insulating sleeves 210 during assembly, preventing the assembled insulating sleeves 210 from wobbling left and right, thereby improving the stability of the connection between adjacent insulating sleeves 210. In other embodiments, the groove 215 can also be a C-shaped groove or other grooves, as long as the width of the groove opening is less than the width of the groove bottom; further details are omitted here.

[0041] In one embodiment, the mounting surface of the insulating protective sleeve 210 has four slots 211 arranged in a square array. The energy storage component includes four supercapacitor cells 220 that are inserted into each slot 211. That is, each spliced ​​energy storage module is provided with four supercapacitor cells 220, and the four supercapacitor cells 220 are evenly distributed on the insulating protective sleeve 210 along a ring path. Further, in this embodiment, a slot 217 is formed in the middle of the mounting surface of the insulating protective sleeve 210. The support component also includes a support column 218 located in the energy storage space. One end of the support column 218 is inserted into the slot 217 of one insulating protective sleeve 210 and connected to the outer casing 100 with screws. The other end of the support column 218 is inserted into the slot 217 of another insulating protective sleeve 210 and connected to the outer casing 100 with screws. In other words, in this embodiment, the top end of the support column 218 is screwed to the upper support plate 150, and the bottom end of the support column 218 is screwed to the lower support plate 160. By setting the support column 218 in the middle of the spliced ​​energy storage module, the spliced ​​energy storage module is fixedly connected to the outer shell 100, while improving the stability of the structure of a single spliced ​​energy storage module. This can prevent the middle part of the insulating protective sleeve 210 from deforming due to overload, thereby extending the service life of the insulating protective sleeve 210 and the spliced ​​energy storage module.

[0042] In addition, in this embodiment, an elastic hook 219 is provided on the support surface next to the support foot 213. A wire groove is formed between the elastic hook 219 and the support foot 213. The conductive wire harness 240 passes through the wire groove, and each wire in the conductive wire harness is electrically connected to the control circuit board 110 and the supercapacitor cell. By setting the elastic hook 219, the conductive wire harness 240 can be limited to prevent the connection between the wire and the first conductive plate 230 and the second conductive plate 300 from breaking due to the pulling of the conductive wire harness 240 during the assembly or maintenance of the supercapacitor module. In addition, in this embodiment, when the conductive wire harness 240 is connected to the first conductive plate 230 and the second conductive plate 300, the conductive wire harness is riveted to the first conductive plate 230 and the second conductive plate 300 to improve the stability of the installation of the conductive wire harness 240.

[0043] In one embodiment, the first conductive sheet 230 has a first conductive contact 232 on each side of the protrusion 231, passing through a through hole 212 and electrically connected to the supercapacitor cell 220. The first conductive sheet 230 has a flat sheet structure. The end of the second conductive sheet 300 has a second conductive contact 310 passing through the through hole 212 and electrically connected to the supercapacitor cell 220. The end of the second conductive sheet 300 away from the second conductive contact 310 is bent to form a bent portion 320 that can pass through the through hole 181 on the front panel 180. In this embodiment, the second conductive sheet used as the positive output electrode of the supercapacitor module and the second conductive sheet used as the negative output electrode of the supercapacitor module can have the same structure or be symmetrical to each other. In addition, in this embodiment, the first conductive sheet 230 is fixed to the supercapacitor cell 220 and electrically connected to the supercapacitor cell by laser welding or screw connection, and the second conductive sheet 300 is fixed to the supercapacitor cell 220 and electrically connected to the supercapacitor cell by laser welding or screw connection. Preferably, the first conductive sheet 230 is fixed to the supercapacitor cell 220 by laser welding and electrically connected to the supercapacitor cell, and the second conductive sheet 300 is fixed to the supercapacitor cell 220 by laser welding and electrically connected to the supercapacitor cell.

[0044] The modular supercapacitor module for energy storage of this invention comprises multiple supercapacitor cells 220, an insulating protective sleeve 210, a first conductive sheet 230, and a conductive wire harness 240, forming a modular energy storage module. By assembling the insulating protective sleeves 210 and connecting the conductive wire harnesses 240 of adjacent modular energy storage modules, different directions and quantities of modular energy storage modules can be assembled. Utilizing different series and parallel combinations of modular energy storage modules, supercapacitor modules of different sizes and electrical specifications can be quickly constructed, meeting the technical parameter requirements of various energy storage systems in terms of voltage and capacity. This modular structure shortens system development time, reduces new material costs, and can quickly respond to changes in different system requirements, thus improving the market competitiveness of the supercapacitor module.
