Description

Technical Field

[0001] The present invention relates to the technical field of energy storage batteries, in particular to a combined energy storage battery. Background Art

[0002] Energy storage batteries primarily refer to batteries used in solar and wind power generation equipment, as well as for storing renewable energy. Different application scenarios place varying demands on the performance of energy storage systems, and a single type of energy storage battery often cannot meet all requirements. For example, while lithium batteries offer advantages such as high energy density and fast response time, they suffer from issues such as short storage cycles and high costs. Flow batteries offer advantages such as long life, high safety, and large energy storage capacity, but they also have relatively low energy density and slow power response time. Combination energy storage batteries combine energy storage technologies with different performance characteristics, leveraging the advantages of each technology to better meet the needs of diverse application scenarios. The reference temperatures for determining the rated capacity of energy storage batteries are 25°C and 20°C. Battery capacity is closely linked to ambient temperature. High temperatures accelerate electrochemical reactions in energy storage batteries, leading to rapid electrolyte evaporation and plate damage. Overcharging is also more likely to occur, severely shortening the battery's service life.

[0003] However, existing energy storage batteries do not have a combined cooling structure, resulting in the need for natural cooling through vents when the internal operating temperature is too high, which reduces the efficiency of the entire cooling process and easily affects the service life of the energy storage battery due to slow cooling efficiency. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a combined energy storage battery, comprising: a protective shell assembly, the protective shell assembly being used for heat dissipation assembly of the combined energy storage battery, the bottom of the protective shell assembly being fixedly mounted with a base plate, the outer surface of the base plate being fixedly mounted with pads on both sides, the interior of the protective shell assembly being movably mounted with a battery pack, and a knob being rotatably mounted on one side of the outer surface of the protective shell assembly;

[0005] A carrier assembly is used for protecting and fixing the combined energy storage battery. The carrier assembly is fixedly mounted on the top of the base plate and disposed inside the protective shell assembly. The carrier assembly fits snugly with the battery pack.

[0006] The battery protective cover is threadedly mounted on the top of the protective shell group. A liquid filling hole plug is fixedly mounted on the top of the battery protective cover. The battery protective cover is arranged above the battery pack and the supporting assembly. When in use, the combined energy storage battery uses electronic devices to combine multiple independent battery modules with different performance characteristics in series, and assembles the combined battery pack in the protective shell group. The battery pack is fixedly installed. Since the capacity of the battery is closely related to the ambient temperature, before the battery pack is assembled inside the protective shell group, the supporting assembly is pre-installed inside the protective shell group, and then the battery pack is installed in the supporting assembly so that the bottom of the battery pack is suspended to facilitate air circulation under the battery pack. At this time, the supporting assembly is arranged between the battery pack and the protective shell group, so that the internal parts of the battery are better fixed together, effectively preventing the battery from falling off during use, and improving the durability and stability of the equipment.

[0007] Preferably, the protective shell assembly includes a shell, with mounting slots fixedly installed on both sides of the outer surface of the shell, positioning slots defined within the mounting slots, and heat sinks fixedly installed within the mounting slots. Four groups of heat sinks are provided, symmetrically arranged around the shell, extending through the positioning slots into the interior of the shell. Square slots are defined on both sides of the bottom of the shell. Staff install the battery pack above the ventilation support, using the square slots in conjunction with the ventilation support to dissipate heat from the bottom of the battery pack. Heat from the center of the shell is discharged through the heat sinks installed on both sides of the mounting slots, thereby accelerating air flow within the shell.

[0008] Preferably, the shell is fixedly mounted on the side of the top of the bottom plate, the shell is arranged below the battery protection cover, the shell is fixedly mounted on the outside of the carrying assembly, and the square groove is connected to the carrying assembly.

[0009] Preferably, the heat sink comprises a semicircular block, which is fixedly mounted within the mounting groove. A hollow sheet is fixedly mounted on both sides of the outer surface of the semicircular block. An extension plate is fixedly mounted on the outer surface of the hollow sheet. An arc-shaped groove is defined within the extension plate and the hollow sheet, and the extension plate extends through the positioning groove and into the interior of the housing. The extension plate is mounted through the positioning groove and mounted on the outside of the battery pack. When heat flows within the housing, some of the heat is discharged along the arc-shaped groove to the outside of the hollow sheet. Because the hollow sheet is curved, dust and impurities carried in the air are less likely to enter the housing when air outside the housing flows into the housing along the arc-shaped groove.

[0010] Preferably, the bearing assembly includes a ventilation support seat, and support plates are fixedly installed at the corners of the outer surface of the ventilation support seat. The support plates are provided in four groups, and the four groups of support plates are symmetrically arranged with the ventilation support seat as the center. The tops of the support plates are fixedly installed with extrusion patches, and there are two extrusion patches, and the tops of the two extrusion patches are fixedly installed with fixed blocks. The staff installs the battery pack on top of the ventilation support seat. During the installation of the battery pack, the extrusion patch installed on the top of the support plate produces friction with the battery pack. Since the extrusion patch is set to a flexible material and its structure protrudes in the direction of the battery pack, during the installation and lowering of the battery pack, the battery pack and the protruding position of the extrusion patch are squeezed, so that the extrusion patch is deformed by force and fits with the battery pack, achieving the effect of stably supporting the side of the battery pack after the battery pack is installed. At this time, during the lowering of the battery pack, the protruding position of the extrusion patch can buffer the battery pack to prevent the battery pack from falling directly on the ventilation support seat and bumping.

[0011] Preferably, the ventilation support is fixedly mounted on the top of the base plate, the support plate is fixedly mounted between the ventilation support and the opposite surface of the shell, the extrusion patch is set to a flexible material, the extrusion patch is extruded and adapted to the side of the battery pack, and the battery pack is movably mounted on the top of the ventilation support.

[0012] Preferably, the ventilation support includes two connecting pieces, a bottom support plate is fixedly mounted between the opposing surfaces of the two connecting pieces, a positioning block is fixedly mounted on the side of the outer surface of the connecting piece, a flow groove is formed on the surface of the connecting piece, and an extension block is fixedly mounted on the outer side of the flow groove. During the use of the energy storage battery, the temperature inside the housing rises. Since the battery pack mounted on the bottom support plate is supported by multiple bottom support plates, the bottom of the battery pack is suspended. The heat in the housing can flow through the spacing between the bottom support plates to the bottom of the housing and be discharged to the outside of the housing along the flow groove and the square groove, thereby accelerating the air flow speed at the bottom of the battery pack and improving the cooling efficiency.

[0013] Preferably, there are several bottom support plates, and the several bottom support plates are adapted to the circulation groove. The positioning block is against the inner wall of the shell. The circulation groove, the extension block and the square groove are arranged opposite to each other, and the square groove is connected to the circulation groove.

[0014] Preferably, the battery protective cover includes a top cover, with side panels fixedly mounted on both sides of the bottom of the top cover, a semiconductor cooling plate fixedly mounted between opposing surfaces of the side panels, and a reinforcement frame fixedly mounted on the outer surface of the side panels. After the staff installs the battery pack in the load-bearing assembly, they install the top cover on the housing. At this time, the semiconductor cooling plate mounted on the bottom of the top cover contacts the battery pack. When the battery pack is hot, the semiconductor cooling plate and phase change material remove heat from the battery pack to achieve the effect of cooling the battery pack, thereby preventing excessive battery temperature from accelerating the electrochemical reaction of the energy storage battery and causing damage to the plate.

[0015] Preferably, the top cover is threadedly mounted on the top of the shell, the side connecting plates and the reinforcement frame are clamped on the outer surface of the fixed block, and the semiconductor cooling plate is arranged above the battery pack.

[0016] The present invention provides a combined energy storage battery. It has the following beneficial effects:

[0017] 1. This combined energy storage battery combines multiple independent battery modules with different performance characteristics in series through electronic devices during use, and assembles the combined battery pack in a protective shell group, which is then fixed and installed. Since the battery capacity is closely related to the ambient temperature, before the battery pack is assembled inside the protective shell group, a supporting assembly is pre-installed inside the protective shell group. The battery pack is then installed in the supporting assembly, so that the bottom of the battery pack is suspended to facilitate air circulation under the battery pack. At this time, the supporting assembly is arranged between the battery pack and the protective shell group, so that the internal parts of the battery are better fixed together, effectively preventing the battery from falling off during use, and improving the durability and stability of the equipment.

[0018] 2. For this combined energy storage battery, the staff installs the battery pack above the ventilation support, and dissipates heat from the bottom of the battery pack through the cooperation of the square groove and the ventilation support, and discharges the heat in the middle of the shell through the heat dissipation parts installed on both sides of the installation groove to accelerate the flow of air in the shell; the extension plate is installed on the outside of the battery pack through the positioning groove. When the heat in the shell flows, part of the heat is discharged to the outside of the hollow sheet along the arc groove. Since the hollow sheet is set in an arc shape, when the air outside the shell flows into the shell along the arc groove, dust and impurities carried in the air are not easy to enter the shell.

[0019] 3. For this combined energy storage battery, the staff installs the battery pack on top of the ventilation support. During the installation of the battery pack, the extrusion patch installed on the top of the support plate generates friction with the battery pack. Since the extrusion patch is set to a flexible material and its structure protrudes toward the battery pack, during the installation and lowering of the battery pack, the battery pack and the protruding position of the extrusion patch are squeezed, so that the extrusion patch is deformed under force and fits with the battery pack, achieving the effect of providing stable support for the side of the battery pack after the battery pack is installed. At this time, during the lowering of the battery pack, the protruding position of the extrusion patch can cushion the battery pack to prevent the battery pack from falling directly on the ventilation support and bumping.

[0020] Fourth, this combined energy storage battery, when the temperature inside the shell increases during the use of the energy storage battery, because the battery pack installed on the bottom support plate is supported by multiple bottom support plates, the bottom of the battery pack is in a suspended state, and the heat in the shell can flow to the bottom of the shell through the spacing between the bottom support plates and be discharged to the outside of the shell along the circulation groove and the square groove, thereby accelerating the air flow speed at the bottom of the battery pack and improving the cooling efficiency.

[0021] 5. For this combined energy storage battery, after the staff installs the battery pack in the carrier assembly, the top cover is installed on the shell. At this time, the semiconductor cooling plate installed at the bottom of the top cover is in contact with the battery pack. When the battery pack is at a high temperature, the heat of the battery pack is taken away by the semiconductor cooling plate and the phase change material to achieve the effect of cooling the battery pack, thereby avoiding the battery temperature being too high, which will accelerate the electrochemical reaction of the energy storage battery and cause damage to the plate.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] The first embodiment, as Figures 1 to 9 As shown, the present invention provides a technical solution: a combined energy storage battery, comprising: a protective shell group 3, the protective shell group 3 being used for heat dissipation assembly of the combined energy storage battery, a bottom plate 8 being fixedly mounted on the bottom of the protective shell group 3, pads 5 being fixedly mounted on both sides of the outer surface of the bottom plate 8, a battery pack 6 being movably mounted inside the protective shell group 3, and a knob 4 being rotatably mounted on one side of the outer surface of the protective shell group 3;

[0034] The protective shell group 3 includes a shell 31, with mounting grooves 34 fixedly installed on both sides of the outer surface of the shell 31. Positioning grooves 35 are provided inside the mounting grooves 34. Heat sinks 33 are fixedly installed inside the mounting grooves 34. Four groups of heat sinks 33 are provided, and the four groups of heat sinks 33 are symmetrically arranged with the shell 31 as the center. The heat sinks 33 extend through the positioning grooves 35 to the interior of the shell 31. Square grooves 32 are provided on both sides of the bottom of the shell 31. The staff installed the battery pack 6 above the ventilation support 72, and the square grooves 32 cooperated with the ventilation support 72 to dissipate heat from the bottom of the battery pack 6. The heat sinks 33 installed on both sides of the mounting grooves 34 expel heat from the middle of the shell 31 to accelerate the flow of air in the shell 31.

[0035] The shell 31 is fixedly mounted on the side of the top of the base plate 8 . The shell 31 is arranged below the battery protection cover 2 . The shell 31 is fixedly mounted on the outside of the carrying component 7 . The square groove 32 is connected to the carrying component 7 .

[0036] The carrier assembly 7 is used for protecting and fixing the combined energy storage battery. The carrier assembly 7 is fixedly mounted on the top of the bottom plate 8. The carrier assembly 7 is arranged inside the protective shell group 3 and fits snugly with the battery pack 6.

[0037] The supporting component 7 includes a ventilation support seat 72, and support plates 74 are fixedly installed at the corners of the outer surface of the ventilation support seat 72. Four groups of support plates 74 are provided, and the four groups of support plates 74 are symmetrically arranged with the ventilation support seat 72 as the center. The tops of the support plates 74 are all fixedly installed with extrusion patches 73. There are two extrusion patches 73, and fixed blocks 71 are fixedly installed on the tops of the two extrusion patches 73. The staff installed the battery pack 6 above the ventilation support 72. During the installation of the battery pack 6, the extrusion patch 73 installed on the top of the support plate 74 generated friction with the battery pack 6. Since the extrusion patch 73 is set to a flexible material and its structure protrudes toward the direction of the battery pack 6, during the installation and lowering of the battery pack 6, the battery pack 6 and the protruding position of the extrusion patch 73 are squeezed, so that the extrusion patch 73 is deformed under force and fits with the battery pack 6, achieving the effect of stably supporting the side of the battery pack 6 after the battery pack 6 is installed. At this time, during the lowering of the battery pack 6, the protruding position of the extrusion patch 73 can buffer the battery pack 6, preventing the battery pack 6 from falling directly on the ventilation support 72 and bumping into it.

[0038] The ventilation support 72 is fixedly installed on the top of the base plate 8, the support plate 74 is fixedly installed between the ventilation support 72 and the opposite surface of the shell 31, the extrusion patch 73 is set to a flexible material, the extrusion patch 73 is extruded and adapted to the side of the battery pack 6, and the battery pack 6 is movably installed on the top of the ventilation support 72.

[0039] The battery protective cover 2 is threadedly mounted on the top of the protective shell group 3. A liquid filling hole screw plug 1 is fixedly mounted on the top of the battery protective cover 2. The battery protective cover 2 is arranged above the battery pack 6 and the supporting assembly 7. When in use, the combined energy storage battery combines multiple independent battery modules with different performance characteristics in series through electronic devices, and assembles the combined battery pack 6 in the protective shell group 3. The battery pack 6 is fixedly installed. Since the capacity of the battery is closely related to the ambient temperature, before the battery pack 6 is assembled inside the protective shell group 3, the supporting assembly 7 is pre-installed inside the protective shell group 3, and then the battery pack 6 is installed in the supporting assembly 7 so that the bottom of the battery pack 6 is suspended to facilitate air circulation under the battery pack 6. At this time, the supporting assembly 7 is arranged between the battery pack 6 and the protective shell group 3, so that the internal parts of the battery are better fixed together, effectively preventing the battery from falling off during use, and improving the durability and stability of the equipment.

[0040] The battery protective cover 2 includes a top cover 21, with side panels 22 fixedly mounted on both sides of the bottom of the top cover 21. A semiconductor cooling plate 24 is fixedly mounted between the opposing surfaces of the side panels 22, and a reinforcement frame 23 is fixedly mounted on the outer surface of the side panels 22. After the staff installs the battery pack 6 within the support assembly 7, the top cover 21 is installed on the housing 31. At this time, the semiconductor cooling plate 24 installed on the bottom of the top cover 21 contacts the battery pack 6. When the battery pack 6 is hot, the semiconductor cooling plate 24 and the phase change material remove heat from the battery pack 6, thereby cooling the battery pack 6 and preventing excessive battery temperature from accelerating the electrochemical reaction of the energy storage battery and causing damage to the plate.

[0041] The top cover 21 is threadedly mounted on the top of the housing 31 , the side connecting plate 22 and the reinforcement frame 23 are clamped on the outer surface of the fixing block 71 , and the semiconductor cooling plate 24 is arranged above the battery pack 6 .

[0042] The second embodiment, based on the first embodiment, see Figures 4 to 6 As shown, the heat sink 33 includes a semicircular block 332, which is fixedly mounted inside the mounting groove 34. A hollow piece 331 is fixedly mounted on both sides of the outer surface of the semicircular block 332. An extension plate 333 is fixedly mounted on the outer surface of the hollow piece 331. An arc-shaped groove 334 is formed inside the extension plate 333 and the hollow piece 331. The extension plate 333 passes through the positioning groove 35 and extends into the interior of the housing 31. The extension plate 333 is installed through the positioning groove 35 and is mounted on the outside of the battery pack 6. When heat flows within the housing 31, part of the heat is discharged to the outside of the hollow piece 331 along the arc-shaped groove 334. Because the hollow piece 331 is arranged in an arc shape, when air outside the housing 31 flows into the housing 31 along the arc-shaped groove 334, dust and impurities carried in the air are not easily entered into the housing 31.

[0043] The third embodiment, based on the first and second embodiments, see Figures 7 to 9 As shown, the ventilation support 72 includes a connecting piece 721, two of which are provided. A bottom support plate 722 is fixedly mounted between the opposing surfaces of the two connecting pieces 721. A positioning block 725 is fixedly mounted on the side of the outer surface of the connecting piece 721. A flow groove 724 is formed on the surface of the connecting piece 721, and an extension block 723 is fixedly mounted on the outer side of the flow groove 724. During the use of the energy storage battery, the temperature inside the shell 31 rises. Since the battery pack 6 mounted on the bottom support plate 722 is supported by multiple bottom support plates 722, the bottom of the battery pack 6 is in a suspended state. The heat inside the shell 31 can flow to the bottom of the shell 31 through the spacing between the bottom support plates 722 and be discharged to the outside of the shell 31 along the flow groove 724 and the square groove 32, thereby accelerating the air flow speed at the bottom of the battery pack 6 and improving the cooling efficiency.

[0044] There are several bottom support plates 722, and the several bottom support plates 722 are adapted to the circulation groove 724. The positioning block 725 is against the inner wall of the shell 31. The circulation groove 724 and the extension block 723 are arranged opposite to the square groove 32, and the square groove 32 is connected to the circulation groove 724.

[0045] During use, the combined energy storage battery combines multiple independent battery modules with different performance characteristics in series through electronic devices, and assembles the combined battery pack 6 in the protective shell group 3, and fixes the battery pack 6. Since the capacity of the battery is closely related to the ambient temperature, before the battery pack 6 is assembled inside the protective shell group 3, the supporting component 7 is pre-installed inside the protective shell group 3, and then the battery pack 6 is installed in the supporting component 7, so that the bottom of the battery pack 6 is in a suspended state to facilitate air circulation under the battery pack 6. At this time, the supporting component 7 is arranged between the battery pack 6 and the protective shell group 3, so that the internal parts of the battery are better fixed together, effectively preventing the battery from falling off during use, and improving the durability and stability of the equipment.

[0046] The staff installed the battery pack 6 above the ventilation support 72, and dissipated heat from the bottom of the battery pack 6 through the cooperation between the square groove 32 and the ventilation support 72, and discharged the heat from the middle position of the shell 31 through the heat sink 33 installed on both sides of the installation groove 34 to accelerate the flow of air in the shell 31.

[0047] The extension plate 333 is installed through the positioning groove 35 and is installed on the outside of the battery pack 6. When the heat in the shell 31 flows, part of the heat is discharged to the outside of the hollow piece 331 along the arc groove 334. Since the hollow piece 331 is set in an arc shape, when the air outside the shell 31 flows into the shell 31 along the arc groove 334, the dust and impurities carried in the air are not easy to enter the shell 31.

[0048] The staff installed the battery pack 6 above the ventilation support 72. During the installation of the battery pack 6, the extrusion patch 73 installed on the top of the support plate 74 generated friction with the battery pack 6. Since the extrusion patch 73 is set to a flexible material and its structure protrudes toward the direction of the battery pack 6, during the installation and lowering of the battery pack 6, the battery pack 6 and the protruding position of the extrusion patch 73 are squeezed, so that the extrusion patch 73 is deformed under force and fits with the battery pack 6, achieving the effect of stably supporting the side of the battery pack 6 after the battery pack 6 is installed. At this time, during the lowering of the battery pack 6, the protruding position of the extrusion patch 73 can buffer the battery pack 6, preventing the battery pack 6 from falling directly on the ventilation support 72 and bumping into it.

[0049] During the use of the energy storage battery, the temperature inside the shell 31 rises. Since the battery pack 6 installed on the bottom support plate 722 is supported by multiple bottom support plates 722, the bottom of the battery pack 6 is in a suspended state. The heat in the shell 31 can flow through the gap between the bottom support plates 722 at the bottom of the shell 31 and be discharged to the outside of the shell 31 along the circulation groove 724 and the square groove 32, thereby accelerating the air flow speed at the bottom of the battery pack 6 and improving the cooling efficiency.

[0050] After the staff installs the battery pack 6 in the supporting assembly 7, the top cover 21 is installed on the shell 31. At this time, the semiconductor refrigeration plate 24 installed at the bottom of the top cover 21 is in contact with the battery pack 6. When the battery pack 6 is at a high temperature, the heat of the battery pack 6 is taken away by the semiconductor refrigeration plate 24 and the phase change material to achieve the effect of cooling the battery pack 6, thereby preventing the battery temperature from being too high, which will accelerate the electrochemical reaction of the energy storage battery and cause damage to the plate.
