Description

Technical Field

[0001] This utility model relates to the field of energy storage combiner cabinet technology, specifically an integrated energy storage combiner cabinet. Background Technology

[0002] An energy storage combiner cabinet is a crucial component of equipment specifically designed for energy storage and distribution. It aggregates and distributes the output current from multiple energy storage units (such as battery modules) to meet the power demands of different loads. Furthermore, it incorporates various protection circuits, such as overcurrent protection, overvoltage protection, and undervoltage protection, enabling real-time monitoring of the energy storage system's operating status to ensure safe and stable operation.

[0003] A smart energy storage combiner cabinet is disclosed in a published patent (publication number: CN221574666U). The cabinet uses heat dissipation holes as mounting holes to install partitions, and the position of the partitions can be changed by selectively installing heat dissipation holes, thereby changing the internal spatial layout of the combiner cabinet.

[0004] However, the aforementioned combiner cabinets employ a distributed layout for their housing, power distribution cabinet, and communication control compartment, resulting in low space utilization within the container. Therefore, to address these issues, an integrated energy storage combiner cabinet is urgently needed. Utility Model Content

[0005] The purpose of this invention is to provide an integrated energy storage combiner cabinet to solve the problem of low container space utilization mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An integrated energy storage combiner cabinet includes a cabinet body and an openable cabinet door. The cabinet body includes an upper power distribution compartment and a lower power management compartment. The power distribution compartment contains an AC power distributor and wiring terminals. The power management compartment contains an industrial control computer, a high-voltage box 1 and a high-voltage box 2, and an uninterruptible power supply (UPS). The high-voltage box 1 and the high-voltage box 2 are mounted on mounting beams inside the cabinet. The AC power distributor, wiring terminals, industrial control computer, and UPS are mounted on a mounting plate inside the cabinet via a mounting mechanism.

[0008] As a further improvement of this utility model: the cabinet door is equipped with an EMS display controller and a BMS display controller. The operation of the components inside the combiner cabinet can be displayed and controlled through the two displays controllers. In addition, three indicator lights are provided below the displays controllers.

[0009] As a further improvement of this utility model, the power management compartment is provided with wiring holes on all four sides, which makes wiring more convenient.

[0010] As a further embodiment of this utility model: the installation mechanism includes an installation groove formed on the installation plate, and the AC side power distributor, terminal block, industrial control computer and uninterruptible power supply are all mounted on the installation plate through a connecting plate, and positioning plates corresponding to the installation groove are fixedly installed on both sides of the connecting plate.

[0011] As a further embodiment of this utility model: the positioning plate is provided with a connecting mechanism, the connecting mechanism includes a connecting block fixedly connected to the positioning plate, a baffle fixedly connected to the upper end of the connecting block and a positioning block fixedly connected to the side of the connecting block, the connecting block, the baffle and the positioning block are perpendicularly distributed to each other and form a vertical positioning area a.

[0012] As a further improvement of this utility model, the positioning block is provided with a positioning screw hole, which is threadedly connected to the mounting plate by bolts.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] High-voltage boxes one and two are mounted on mounting beams inside the cabinet. AC power distributors, terminal blocks, industrial control computers, and uninterruptible power supplies (UPS) are mounted on mounting plates inside the cabinet via mounting mechanisms. This installation method improves the space utilization within the cabinet. The design optimizes the installation and maintenance process, and the use of AC power distributors and terminal blocks reduces the need for plug-in components, improving the efficiency and accuracy of signal and action transmission. Furthermore, the integrated design, achieved by dividing the cabinet into a power distribution compartment and a power management compartment, allows for tighter connections between components.

[0022] Please see Figure 1 and Figure 2 An integrated energy storage combiner cabinet includes a cabinet body with an openable door at the front. An EMS display controller 1 and a BMS display controller 2 are mounted on the door. These two displays controllers can display and control the operation of the components inside the combiner cabinet. Below the displays controllers are three indicator lights 3, each displaying a different color to represent one of the three states of the combiner cabinet: red for power, yellow for fault, and green for normal operation. The status of the energy storage combiner cabinet can be quickly determined by the color of the indicator lights 3.

[0023] Furthermore, ventilation holes are provided at the bottom of the cabinet door, allowing heat exchange between the interior of the energy storage combiner cabinet and the outside environment, thus achieving a heat dissipation effect.

[0024] like Figure 3 As shown, the cabinet includes an upper power distribution compartment 11 and a lower power management compartment 12. The power distribution compartment 11 includes an AC power distributor 4 and a terminal block 5. The power management compartment 12 includes an industrial control computer 6, a high-voltage box 1 7, a high-voltage box 2 8, and an uninterruptible power supply 10.

[0025] The high-voltage box 7 and high-voltage box 8 are mounted on the mounting beam inside the cabinet. The AC-side power distributor 4, terminal blocks 5, industrial control computer 6, and uninterruptible power supply 10 are mounted on the mounting plate 13 inside the cabinet via a mounting mechanism. This installation method improves the space utilization within the cabinet, optimizes the installation and maintenance process, and reduces the need for plug-ins by using the AC-side power distributor 4 and terminal blocks 5, thus improving the efficiency and accuracy of signal and action transmission. Furthermore, the integrated design, achieved by dividing the cabinet into a power distribution compartment 11 and a power management compartment 12, ensures tighter and more reliable connections between components.

[0026] Furthermore, the power management compartment 12 is provided with wiring holes 9 on all four sides. The design of the wiring holes 9 makes wiring more convenient and facilitates the operation and maintenance of the energy storage power station. The modular high-voltage box design makes the replacement and maintenance of various components more convenient.

[0027] like Figure 4 As shown, the installation mechanism includes a mounting slot 14 formed in the mounting plate 13. The AC side power distributor 4, terminal block 5, industrial control computer 6, and uninterruptible power supply 10 are all mounted on the mounting plate 13 via a connecting plate 15. Positioning plates 16 corresponding to the mounting slot 14 are fixedly installed on both sides of the connecting plate 15. The connecting plate 15 can be placed on the mounting slot 14 using the positioning plates 16. Because the mounting plate 13 is vertically placed inside the energy storage combiner cabinet, the mounting slot 14 provides a restraining force to the positioning plates 16 through its upper and lower edges, thus achieving the installation effect. However, although this placement method is quick and conforms to the modular installation of the energy storage combiner cabinet, this installation is not stable. Therefore, the following improvements were made.

[0028] like Figure 5 As shown, a connecting mechanism 17 is provided on the positioning plate 16. The connecting mechanism 17 includes a connecting block 171 fixedly connected to the positioning plate 16, a baffle 172 fixedly connected to the upper end of the connecting block 171, and a positioning block 173 fixedly connected to the side of the connecting block 171. The connecting block 171, the baffle 172, and the positioning block 173 are perpendicularly distributed to each other. In this embodiment, the positioning block 173 is provided with a positioning screw hole, which can be threadedly connected to the mounting plate 13 by bolts. The connecting block 171, the baffle 172, and the positioning block 173 are vertically designed to form a positioning area a. The right-angled side of the positioning area a fits against the corner of the mounting groove 14, and the connecting block 171, the baffle 172, and the positioning block 173 simultaneously contact three surfaces of the mounting groove 14. Then, the positioning bolts are used to connect to the mounting plate 16 through the positioning screw holes, thus achieving the effect of installing the connecting mechanism 17 on the mounting plate 13. In this embodiment, the right-angled positioning area a formed by the connecting block 171, the baffle 172, and the positioning block 173 can wrap around the two right-angled sides of the mounting groove 14. After being wrapped, the positioning plate 16 in the mounting groove 14 is subjected to a covering force. Due to the presence of the covering force, the positioning plate 16 is subjected to a restrictive force in three directions. On the one hand, this facilitates the installation and disassembly of various components in the modular energy storage combiner cabinet. On the other hand, it increases the stabilizing force of the mounting plate 13 on the positioning plate 16, preventing the positioning plate 16 from loosening during use and causing the electrical components to malfunction.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
