Description

Technical Field

[0001] This invention is an energy storage charging cabin, belonging to the field of energy storage technology. Background Technology

[0002] An energy storage charging cabin is a modular device integrating an energy storage system and charging functions. By integrating battery energy storage, charging modules, and an intelligent management system, it achieves the storage, distribution, and external charging of electrical energy. Its core working principle is: storing electrical energy through built-in rechargeable battery clusters, and then converting DC power into AC power of the mains standard (or directly outputting DC power) via related electrical components, thereby achieving energy storage, allocation, and flexible power supply. Simply put, an energy storage charging cabin can be understood as a "portable high-capacity power bank / backup power source," a key facility in the new energy field that combines flexibility and practicality. With the booming development of the new energy industry, the application of energy storage charging cabins is becoming increasingly widespread, covering multiple important areas such as fast charging of electric vehicles, distributed energy storage, and emergency power supply.

[0003] Currently, energy storage charging compartments typically consist of multiple battery clusters (the number can be increased or decreased according to actual needs), distribution modules such as high-voltage boxes, and converter modules such as energy storage inverters. All modules are integrated and installed inside a cabinet-type casing. The distribution modules are electrically connected to the converter modules and battery clusters. The battery clusters generally consist of multiple battery packs, which are arranged vertically on corresponding frames and connected in series via multiple connection joints. This installation method not only occupies a large amount of space but also requires a larger casing, increasing production costs. Furthermore, the connection joints are located at the casing door; during maintenance or assembly, workers are prone to accidentally touching the assembled connection joints, significantly increasing the probability of short circuits and other malfunctions, compromising safety and ultimately affecting the normal operation of the equipment.

The structure formed by the auxiliary blocks seals the front opening of the space between the first and second battery packs, thus hiding the functional box, plug, and socket. This effectively reduces the probability of short circuits caused by accidental contact, ensuring high safety and effective performance. In addition, the cooperation of the locking strip and positioning strip with the corresponding slot effectively reduces the probability of the first or second battery pack sliding, ensuring effective insertion between the plug and the corresponding socket, and effectively guaranteeing the performance.

The high-voltage box 4 is responsible for the distribution, protection and monitoring of high-voltage power, isolating fault circuits, and ensuring the safety of personnel and equipment. It is integrated with devices such as circuit breakers, fuses, and contactors. The energy storage converter 5 can convert AC power to DC power to charge the battery cluster formed by multiple first battery packs 2 and multiple second battery packs 3, or convert the DC power of the battery cluster to AC power to charge loads such as vehicles. Multiple first battery packs 2 located on the right side of the function box 6 are stacked vertically on the upper end of the frame 41, and multiple second battery packs 3 located on the left side of the function box 6 are stacked vertically on the upper end of the frame 41. The second battery packs 3 have the same structure as the first battery packs 2 and are arranged opposite to each other.

The upper and lower ends of the first battery pack 2 are recessed inward to form a slot 22, and the front and rear ends of the slot 22 extend to the front and rear ends of the first battery pack 2, respectively. The upper and lower ends of the first battery pack 2 are also provided with slots 22. A positioning strip 221 is installed between two adjacent first battery packs 2, and the upper and lower ends of the positioning strip 221 extend into the two adjacent slots 22, respectively.

Two locking strips 42 are symmetrically arranged on the upper end of the frame 41, and the two locking strips 42 are respectively inserted into the locking groove 22 at the lower end of the bottom first battery pack 2 and the locking groove 22 at the lower end of the bottom second battery pack 3. The two locking strips 42 work together to position the bottom first battery pack 2 and the bottom second battery pack 3 on the upper end of the frame 41. Baffles 421 are detachably connected to the front and rear ends of the two locking strips 42 by bolts. The baffles 421 on the left and right sides are respectively attached to the outer ends of the first battery pack 2 and the second battery pack 3. The baffles 421 prevent misalignment between the bottom first battery pack 2 and the second battery pack 3. Multiple auxiliary blocks 21 are respectively placed on the right end of multiple first battery packs 2 and on the left end of multiple second battery packs 3, and two adjacent auxiliary blocks 21 are attached to each other, and the bottom auxiliary block 21 is attached to the upper end of the frame 41. The multiple auxiliary blocks 21 are used in conjunction to allow multiple first battery packs 2 and multiple second battery packs 3 to be stacked alternately, and to hide the equipment used for power connection. The first partition 11 located at the right end of the frame 41 is installed inside the housing 1. The first partition 11 divides the space inside the housing 1 into two cavities and provides a mounting carrier for components such as refrigeration equipment. The refrigeration equipment extending to the left end of the first partition 11 is set on the right end of the first partition 11. The refrigeration equipment dissipates heat from the equipment on the left side of the first partition 11. The refrigeration equipment can be an air conditioner 12. The cable 51 is set on the right end of the first partition 11. One end of the cable 51 passes through the first partition 11 and is electrically connected to the energy storage converter 5. The other end of the cable 51 extends out of the front side of the housing 1. The cable 51 is used for charging or discharging. The function box 6 is installed on the upper end of the frame 41, and is located between the first battery pack 2 and the second battery pack 3. The function box 6 provides a mounting carrier for components such as the movable plate 65. Multiple movable plates 65 are slidably connected to both ends of the function box 6, and the movable plates 65 extend into the function box 6. The movable plates 65 provide a mounting carrier for the plug 64. The upper surfaces of the multiple movable plates 65 are recessed downward to form through grooves 66, which penetrate the movable plates 65. Through the through grooves 66, the bidirectional screw 61 passes through the corresponding movable plate. 65, and install multiple plugs 64 on the outward ends of multiple movable plates 65 respectively. Sockets 23 are embedded in the middle of the inward ends of multiple first battery packs 2 and multiple second battery packs 3. Multiple plugs 64 are plugged into the outward ends of multiple sockets 23 respectively. Adjacent plugs 64 are electrically connected to each other. The uppermost plug 64 and the lowermost plug 64 are electrically connected to the high-voltage box 4. Multiple plugs 64 and multiple sockets 23 are used together to connect multiple first battery packs 2 and multiple second battery packs 3 in series.

The uppermost bidirectional screw 61 is rotatably connected to the top of the functional box 6, and the lowermost bidirectional screw 61 is rotatably connected to the bottom of the functional box 6. The multiple bidirectional screws 61 pass through multiple through slots 66, and the bidirectional screws 61 are movably connected to the through slots 66. The two corresponding sleeves 62 can move relative to each other through the bidirectional screws 61. Two sleeves 62 are symmetrically threaded to the annular ends of multiple bidirectional screws 61. The sleeves 62 provide a mounting carrier for the support arms 63. The two support arms 63, which are arranged in a V-shape with a narrower outer side and a wider inner side, are movably mounted on the outer ends of the two sleeves 62 respectively. The other ends of the two support arms 63 are movably mounted on the upper and lower ends of the corresponding movable plates 65 respectively. The two support arms 63 work together to make the movable plates 65 move outward or inward.

[0018] During assembly, the high-voltage box 4 and the energy storage converter 5 are first installed into the frame 41 inside the housing 1, and the high-voltage box 4 and the energy storage converter 5 are electrically connected. Then, the high-voltage box 4 is electrically connected to the uppermost plug 64 and the lowermost plug 64, and the cable 51 is electrically connected to the energy storage converter 5, thereby completing the initial circuit connection inside the housing 1. Remove the baffles 421 at the front end of both clips 42, then place a first battery pack 2 on the upper end of the frame 41, insert the right clip 42 into the slot 22 at the lower end of the first battery pack 2, and push the first battery pack 2 backward so that the first battery pack 2 makes contact with the baffle 421 at the rear end of the right clip 42. At this time, the corresponding auxiliary block 21 is attached to the upper end of the frame 41. Then reinstall the right baffle 421 on the front end of the right clip 42 so that the first battery pack 2 is installed in a restricted positioning manner. Then, place a second battery pack 3 on the left side of the card strip 42 and insert the left side of the card strip 42 into the card slot 22 at the lower end of the second battery pack 3. Then push the second battery pack 3 backward so that the second battery pack 3 makes contact with the baffle 421 at the rear end of the left side of the card strip 42. At this time, the corresponding auxiliary block 21 on the second battery pack 3 is attached to the upper end of the auxiliary block 21 on the installed first battery pack 2. Then reinstall the baffle 421 on the front end of the left side of the card strip 42 so that the second battery pack 3 is installed in a restricted positioning manner. Next, disassemble the straight plates 222 at the front end of the two positioning strips 221, and then insert the two positioning strips 221 into the slots 22 at the top end of the installed first battery pack 2 and the second battery pack 3 respectively. Make the straight plates 222 at the rear end of the two positioning strips 221 attach to the rear end of the first battery pack 2 and the rear end of the second battery pack 3 respectively. Then place the new first battery pack 2 on the upper end of the right positioning strip 221 and insert the right positioning strip 221 into the slot 22 at the lower end of the new first battery pack 2. At the same time, make the straight plate 222 on the right rear side attach to the rear end of the new first battery pack 2. Then reinstall the straight plate 222 that was disassembled on the right side onto the front end of the right positioning strip 221, so that the straight plate 222 on the front side attaches to the front end of the two installed first battery packs 2 respectively, so that the new first battery pack 2 is positioned and installed. At this time, the auxiliary block 21 on the new first battery pack 2 attaches to the upper end of the installed uppermost auxiliary block 21. Next, place the new second battery pack 3 on the upper end of the positioning strip 221 on the left side, and insert the positioning strip 221 into the slot 22 at the lower end of the new second battery pack 3. At the same time, make the straight plate 222 on the left rear side adhere to the rear end of the new second battery pack 3. Then, reinstall the straight plate 222 that was removed on the left side onto the front end of the positioning strip 221 on the left side, so that the straight plate 222 on the front side adheres to the front ends of the two installed second battery packs 3 respectively, so that the new second battery pack 3 is positioned and installed. At this time, the auxiliary block 21 on the new second battery pack 3 adheres to the upper end of the auxiliary block 21 of the installed first battery pack 2. Repeat the above steps to realize the alternating combination and stacking of multiple first battery packs 2 and multiple second battery packs 3, thereby combining the traditional two sets of battery cluster structures into one, effectively reducing the space occupied by the assembled battery cluster, effectively reducing production costs, and effectively ensuring the performance. Then, the rod structure formed by multiple bidirectional screws 61 is rotated. Since the bidirectional screws 61 are threadedly connected to the two sleeves 62, the rotation of the bidirectional screws 61 will cause the corresponding two sleeves 62 to move inward, thereby causing the corresponding two support arms 63 to move inward, and then causing the corresponding two support arms 63 to move outward, thereby causing the corresponding movable plate 65 to move outward, and thus causing the corresponding plug 64 to move outward, so that the plug 64 can be inserted into the corresponding socket 23. This realizes the series electrical connection of multiple first battery packs 2 and multiple second battery packs 3 in one operation, effectively reducing the complexity of operation, effectively reducing the probability of damage to the first battery pack 2 or the second battery pack 3, ensuring high safety and effective use. At this time, the cooperation of the locking strip 42 and the positioning strip 221 with the corresponding slot 22 effectively reduces the probability of slippage of the first battery pack 2 or the second battery pack 3, effectively ensuring that the plug 64 is effectively inserted into the corresponding socket 23, and effectively ensuring the use effect. In addition, the auxiliary blocks 21 on the first battery pack 2 and the auxiliary blocks 21 on the second battery pack 3 are alternately attached. At this time, the structure formed by the multiple auxiliary blocks 21 seals the front opening of the space between the first battery pack 2 and the second battery pack 3, realizing the concealment of components such as the function box 6, the plug 64 and the socket 23, effectively reducing the probability of short circuits caused by accidental contact, etc., with high safety and effectively ensuring the use effect.

Through the first pipes 212, the liquid outlet pipe 673 or the liquid return pipe 672 is guided into the auxiliary tank 211 on the one hand, and the coolant in the auxiliary tank 211 is restricted on the other hand. Two annular grooves are symmetrically opened at the annular end of the liquid outlet pipe 673 and the annular end of the liquid return pipe 672. The annular grooves provide installation space for the sealing rings. The sealing rings are installed on the annular grooves.

At this time, the second to last liquid outlet pipe 673 and the liquid return pipe 672 on the lower side are respectively inserted into the two pipe structures at the rear end of the auxiliary block 21 of the second battery pack 3, so that the two inlets and outlets on the auxiliary block 21 of the second battery pack 3 are connected to the corresponding liquid outlet pipe 673 and liquid return pipe 672 respectively, which can also assist in the installation of the second battery pack 3. Next, insert the two positioning strips 221 into the slots 22 at the top of the installed first battery pack 2 and the second battery pack 3 respectively. Then, place the new first battery pack 2 on the upper end of the positioning strip 221 on the right side and insert the positioning strip 221 on the right side into the slot 22 at the bottom of the new first battery pack 2. At the same time, push the new first battery pack 2 backward to the limit position. At this time, the third-to-last liquid outlet pipe 673 and the liquid return pipe 672 on the lower side are respectively inserted into the two pipe structures at the rear end of the auxiliary block 21 of the new first battery pack 2, so that the two inlets and outlets on the auxiliary block 21 of the new first battery pack 2 are connected to the corresponding liquid outlet pipe 673 and liquid return pipe 672 respectively. This can also assist in the installation of the new first battery pack 2. Next, place the new second battery pack 3 on the upper end of the positioning strip 221 on the left side, and insert the positioning strip 221 into the slot 22 at the lower end of the new second battery pack 3. At the same time, push the new second battery pack 3 backward to the limit position. At this time, the fourth-to-last liquid outlet pipe 673 and the liquid return pipe 672 on the lower side are respectively inserted into the two pipe structures at the rear end of the auxiliary block 21 of the new second battery pack 3, so that the two inlets and outlets on the auxiliary block 21 of the new second battery pack 3 are connected to the corresponding liquid outlet pipe 673 and liquid return pipe 672 for installation. This can also assist in the installation of the new second battery pack 3. Following the steps described above, multiple first battery packs 2 and multiple second battery packs 3 are stacked alternately. At this time, multiple liquid outlet pipes 673 and multiple liquid return pipes 672 are connected to multiple corresponding auxiliary blocks 21. Then, through the rod structure formed by multiple bidirectional screws 61, sleeve 62, support arm 63 and movable plate 65, multiple plugs 64 on the left and right sides move outward synchronously, thereby allowing multiple plugs 64 to be inserted into multiple sockets 23 synchronously, thus completing the series electrical connection of multiple first battery packs 2 and multiple second battery packs 3. When in use, the water pump 13 is started to extract the coolant in the storage tank 14 and deliver the extracted coolant through the first pipe 212 to the cavity located at the left end of the second partition 671 in the rectangular box 67. Then, the coolant in the cavity located at the left end of the second partition 671 in the rectangular box 67 is divided into multiple outlet pipes 673. Then, the coolant in the multiple outlet pipes 673 is delivered to multiple corresponding auxiliary blocks 21. Then, the coolant in the auxiliary blocks 21 is delivered to the cooling pipes on the corresponding first battery pack 2 or second battery pack 3 and flows, thereby performing water cooling heat dissipation treatment on the first battery pack 2 and the second battery pack 3. The cooled coolant returns to the corresponding auxiliary block 21, and then the cooled coolant in the auxiliary block 21 is transported to the return pipe 672. The coolant in the return pipe 672 is then transported to the cavity located at the right end of the second partition 671 in the rectangular box 67. The coolant in the cavity located at the right end of the second partition 671 in the rectangular box 67 is then returned to the storage tank 14 through the second pipe 213. At this time, the air conditioner 12 also cools the coolant in the storage tank 14, realizing independent heat dissipation for the first battery pack 2 and the second battery pack 3. This effectively reduces the probability of overheating due to stacking factors, effectively reduces the probability of rapid wear of the first battery pack 2 and the second battery pack 3, and ensures high safety and effective performance.

[0021] Example 3: Figures 11-13 As shown, the positioning box 223 is installed between two adjacent first battery packs 2, and the upper and lower ends of the positioning box 223 extend into the interior of two adjacent slots 22 respectively. The positioning box 223 and the slots 22 are used together to position and install the two adjacent first battery packs 2 or the two adjacent second battery packs 3. The threaded rod 226 is rotatably connected in the positioning box 223. The moving plate 225 moves back and forth through the threaded rod 226. The moving plate 225, which is slidably connected in the positioning box 223, is threaded to the annular end of the threaded rod 226. The positioning post 224 is lifted by the moving plate 225. Multiple trapezoidal grooves 227 are formed by inward recesses on both the upper and lower ends of the movable plate 225, and the trapezoidal grooves 227 extend to the left and right ends of the movable plate 225 respectively. The trapezoidal grooves 227 are arranged to be narrower at the front and wider at the back. Multiple positioning posts 224 are slidably connected to both the upper and lower ends of the positioning box 223. The positioning posts 224 have a T-shaped structure, and the column part of the positioning post 224 extends into the positioning box 223 and is slidably connected to the positioning box 223. The horizontal plate part of the positioning post 224 is attached to the outer end of the movable plate 225. The positioning posts 224 and the trapezoidal grooves 227 are arranged alternately. Multiple positioning holes are formed by outward recesses on the outer wall inside the slot 22. The column parts of the multiple positioning posts 224 are inserted into the multiple positioning holes respectively. The multiple positioning posts 224 and the multiple positioning holes are used to position and install two adjacent first battery packs 2 or two adjacent second battery packs 3.

[0022] During assembly, the high-voltage box 4 and the energy storage converter 5 are first installed into the frame 41 inside the housing 1, and the high-voltage box 4 and the energy storage converter 5 are electrically connected. Then, the high-voltage box 4 is electrically connected to the uppermost plug 64 and the lowermost plug 64, and the cable 51 is electrically connected to the energy storage converter 5, thereby completing the initial circuit connection inside the housing 1. Place a first battery pack 2 on the upper part of the frame 41, insert the right-side locking strip 42 into the lower slot 22 of the first battery pack 2, and push the first battery pack 2 backward to the limit position to position the first battery pack 2. Then place a second battery pack 3 on the left-side locking strip 42, insert the left-side locking strip 42 into the lower slot 22 of the second battery pack 3, and push the second battery pack 3 backward to the limit position to position the second battery pack 3. Next, insert the two positioning boxes 223 into the slots 22 at the top of the installed first battery pack 2 and the second battery pack 3 respectively. At this time, the horizontal plate of the positioning post 224 is located in the trapezoidal groove 227. Then, place the new first battery pack 2 on the upper end of the positioning box 223 on the right and insert the positioning box 223 on the right into the slot 22 at the lower end of the new first battery pack 2. Then, rotate the threaded rod 226 on the positioning box 223 on the right. Since the threaded rod 226 is threadedly connected to the moving plate 225, the rotation of the threaded rod 226 causes the moving plate 225 to move forward along the positioning box 223. This causes multiple trapezoidal slots 227 to move forward, thereby causing the inclined surface of the trapezoidal slots 227 to move relative to the horizontal plate portion of the corresponding positioning post 224, thereby causing the corresponding positioning post 224 to move outward, thereby causing the post portion of the positioning post 224 to insert into the corresponding positioning hole, and using the plane on the moving plate 225 located between two adjacent trapezoidal slots 227 to restrict the positioning post 224. At this time, multiple positioning posts 224 and multiple corresponding positioning holes work together to restrict the installation between two adjacent first battery packs 2. Next, place the new second battery pack 3 on the upper end of the positioning box 223 on the left, and insert the positioning box 223 on the left into the slot 22 at the lower end of the new second battery pack 3. Then, using the threaded rod 226 and the moving plate 225 in the positioning box 223 on the left, move the multiple positioning posts 224 outward, so that the post part of the positioning post 224 is inserted into the corresponding positioning hole, thereby restricting the installation between two adjacent second battery packs 3. The same steps as above are performed to alternately stack and install multiple first battery packs 2 and multiple second battery packs 3. By using the positioning box 223, positioning post 224 and other components in cooperation with the corresponding slot 22, the first battery pack 2 or the second battery pack 3 can be positioned and installed. This effectively reduces the probability of the first battery pack 2 or the second battery pack 3 sliding, effectively ensures that the plug 64 and the corresponding socket 23 can be inserted effectively, and effectively ensures the use effect.
