[0001] This application relates to the field of energy storage cabinet technology, and in particular to an energy storage power conversion control box and an industrial energy storage cabinet. Background Technology

[0002] With the rapid development of renewable energy and the continuous growth of grid peak-shaving demand, industrial energy storage systems, as important devices for energy storage and regulation, have been widely used in industrial scenarios. Industrial energy storage cabinets, as the core carrier of energy storage systems, typically integrate multiple key functional units to achieve efficient energy conversion, storage, and management.

[0003] In existing industrial energy storage cabinet designs, there are typically three units: a Power Conversion System (PCS) responsible for converting DC to AC power, a Power Supply and Protection Unit (PSU) responsible for power supply and protection, and a Battery Management System (BMS) responsible for status detection and control. These three units are usually designed as relatively independent modules, each housed in its own separate enclosure or compartment, and then assembled within the overall energy storage cabinet. This split-type layout, where each unit is independently housed and separated from the others, occupies a significant amount of internal space within the industrial energy storage cabinet, resulting in low overall space utilization.

[0046] Please see Figures 1 to 6 This application provides an energy storage power conversion control box 100, which is installed in an industrial energy storage cabinet and is used for DC-AC conversion, power supply and protection, and power status detection and control of the industrial energy storage cabinet.

[0047] Specifically, the energy storage power conversion control box 100 includes a box body 10, a partition unit 20, a power conversion unit 40, a power supply and protection unit 50, and a battery management unit 60. The box body 10 has a receiving cavity 11. The partition unit 20 is arranged in the receiving cavity 11, and the partition unit 20 divides the receiving cavity 11 into a first cavity 21 and a second cavity 22 in the height direction of the box body 10. The first cavity 21 is located above the second cavity 22. The power conversion unit 40 includes a power conversion module 41 and a power storage module 42. The power conversion module 41 is arranged in the first cavity 21 and has an energy input terminal 43 and an energy output terminal 44. The power storage module 42 is arranged in the second cavity 22 and is electrically connected to the energy output terminal 44. The power supply and protection unit 50 is arranged in the second cavity 22 and is electrically connected to the energy input terminal 43. The battery management unit 60 is arranged in the first cavity 21 and is electrically connected to the power conversion module 41.

[0048] In existing technologies, the power conversion unit 40, power supply and protection unit 50, and battery management unit 60 are typically designed as relatively independent modules, each housed in its own separate enclosure 10 or compartment, and then assembled within the overall energy storage cabinet. This split layout, where each unit is independently housed and separated, occupies a significant amount of space within the industrial energy storage cabinet, resulting in low overall space utilization. Furthermore, the independent enclosures 10 increase material costs, and the need for long cables connecting the units further increases costs; long-distance cable transmission can also lead to signal attenuation. This application addresses this issue by installing a partition unit 20 within the enclosure 10, dividing the accommodating cavity 11 into a first cavity 21 and a second cavity 22, and rationally assembling the power conversion unit 40, power supply and protection unit 50, and battery management unit 60 within the enclosure 10. This allows for the integration of these three units into a single enclosure 10, reducing the space occupied within the industrial energy storage cabinet and improving its space utilization. Furthermore, by integrating the three modules into a single enclosure 10, the cost of the enclosure 10 and cables can be reduced, and the cable travel distance is shorter, thus avoiding signal attenuation issues.

[0049] like Figure 1 and Figure 2 As shown, the box 10 is provided with a current inlet 12 and a current outlet 13, which are used for current to flow into and out of the energy storage power conversion control box 100, respectively.

[0050] Furthermore, the housing 10 is also provided with a plurality of heat dissipation holes 14 and a cooling fan 15. The heat dissipation holes 14 and the cooling fan 15 are respectively provided on the housing 10 of the first cavity 21 and the second cavity 22. The outside air is drawn into the first cavity 21 and the second cavity 22 through the cooling fan 15 and discharged through the heat dissipation holes 14, thereby dissipating heat from the first cavity 21 and the second cavity 22.

[0051] like Figures 2 to 6 As shown, the partition unit 20 includes a partition 23 and an insulating plate 24. The partition 23 is installed in the accommodating cavity 11 and divides the accommodating cavity 11 into two independent cavities, a first cavity 21 and a second cavity 22. The insulating plate 24 is laid on the side of the partition 23 near the first cavity 21. The power conversion unit 40 and the battery management unit 60 are mounted on the insulating plate 24. In this way, by setting the partition 23, the housing 10 can be divided into the first cavity 21 and the second cavity 22. By setting the insulating plate 24 on the partition 23, the devices between the first cavity 21 and the second cavity 22 can be insulated, preventing the devices located in the first cavity 21 and the second cavity 22 from affecting each other.

[0052] In one embodiment, the partition unit 20 further includes a maintenance plate 25. A maintenance notch 231 is provided on the partition 23. The maintenance plate 25 covers the maintenance notch 231 and is detachably connected to the partition 23. The power supply and protection unit 50 is disposed at the maintenance notch 231. Thus, since the power supply and protection unit 50 is prone to problems, by placing the power supply and protection unit 50 at the maintenance notch 231, it is convenient to repair or replace the power supply and protection unit 50 when it malfunctions, thereby shortening maintenance time.

[0053] In other embodiments, the partition 23 may further include a fixed plate (not shown) and a movable plate (not shown). The fixed plate is mounted on the housing 10, and the movable plate is slidably connected to the fixed plate and is used to support the battery management unit 60. The housing 10 has a notch at a corresponding position on the movable plate, allowing the movable plate to be pulled out / pull back through the notch. Insulating plates 24 are respectively provided on the fixed plate and the movable plate. Thus, by providing the notch and the movable plate that can be pulled out / pull back relative to the notch, it is convenient to repair or replace the battery management unit 60 when it malfunctions, thereby shortening maintenance time. It is understood that in other embodiments, other modules can also be placed on the movable plate to facilitate maintenance of modules placed on the movable plate. The specific arrangement can be configured according to the user's needs and will not be elaborated here.

[0054] Here, sliding cooperation between the fixed plate and the movable plate can be achieved by setting guide rails on the fixed plate and sliders on the movable plate; or by setting slide grooves on the fixed plate and sliders on the movable plate; or by setting guide rods on the fixed plate and guide sleeves on the movable plate.

[0055] like Figure 2 and Figure 3 As shown, the energy storage power conversion control box 100 also includes a conductive connection component 30, which includes a copper busbar 31 and cables (not shown). The current inlet 12 and the power conversion module 41, the power conversion module 41 and the power storage module 42, and the power storage module 42 and the current outlet 13 are connected by the copper busbar 31 because the current passing through them is relatively large. Other structures are connected by cables. It should be noted that the copper busbar 31 can also be replaced by aluminum busbars, busbars, etc., and the cables can also be replaced by wires, signal transmission lines, etc. When the function is signal transmission, wireless signal connection can also be used instead. Users can choose according to their needs. Such structures are common in the prior art and will not be described in detail here.

[0056] like Figure 2 and Figure 4 As shown, the power conversion module 41 includes a power board 411, a capacitor 412, and an IGBT circuit board 413. The power board 411 is fixed on the insulating plate 24, and the capacitor 412 and the IGBT circuit board 413 are mounted on the power board 411. Here, the power board 411 is used to support the core power devices; the capacitor 412 is used to stabilize the voltage and filter out high-frequency ripple and transient interference in the current; the IGBT circuit board 413 integrates the IGBT power devices and their drive and protection circuits. The three work together to enable the power conversion module 41 to perform the core functions of power conversion, power regulation, and system protection.

[0057] Furthermore, the power storage module 42 includes structures such as a large capacitor 421 and a PCS output board 422. The large capacitor 421 is used to smooth current fluctuations, stabilize the bus voltage, and provide instantaneous power support during charging and discharging. The PCS output board 422 is used to realize safe power output, system isolation, and reliable transmission.

[0058] In summary, by setting up a power conversion module 41 including a power board 411, a capacitor 412 and an IGBT circuit board 413, and a power storage module 42 including a large capacitor 421 and a PCS output device, power conversion in an industrial energy storage cabinet can be realized. Its specific structure is quite common in the prior art and will not be described in detail here.

[0059] The power conversion unit 40 also includes a power conversion control board 45, which is disposed in the first cavity 21 and fixed on the insulating plate 24, and is used to control the power conversion of the power conversion unit 40.

[0060] In one embodiment, the power conversion control board 45 and the battery management unit 60 are integrated on the same circuit board. For example, both the power conversion control board 45 and the battery management unit 60 can be configured as modules on a single PCB board, thus achieving their integration. In this way, by integrating the power conversion control board 45 and the battery management unit 60, the integration level of the energy storage power conversion control box 100 can be improved, and the manufacturing cost can be reduced.

[0061] In one embodiment, the battery management unit 60 and the power conversion module 41 are connected wirelessly. This eliminates the need for physical communication cables between them, thereby reducing the wiring complexity within the first cavity 21, reducing potential failure points, and facilitating maintenance.

[0062] like Figure 2 and Figure 3 As shown, the power supply and protection unit 50 is located in the second cavity 22, and the copper busbar 31 is connected to the current inlet 12 first, then connected to the power supply and protection unit 50, and then connected to the power conversion module 41. The power supply and protection unit 50 includes a fuse 51, a shunt 52, and a main relay 53. The fuse 51 is an overcurrent protection device for the circuit. When the current exceeds a set value (such as a short circuit or severe overload), the fuse element inside the fuse 51 melts, cutting off the circuit and protecting downstream equipment from damage caused by high current. The shunt 52 is used to measure the current, and the main relay 53 is used to connect or disconnect the main power supply (such as a battery pack) from the downstream load (such as an inverter or electrical equipment) when needed (such as during system startup, shutdown, fault protection, or maintenance).

[0063] In one embodiment, the energy storage power conversion control box 100 further includes a baffle fan 70, which is disposed within the second cavity 22 and positioned between the power conversion unit 40 and the battery management unit 60 in the width direction of the box 10. The number of baffle fans 70 can be configured to be multiple, such as two, three, four, or five. Thus, by setting the baffle fan 70, thermal convection can be formed within the first cavity 21, optimizing the airflow circulation of the first cavity 21, thereby eliminating ventilation dead zones and improving the heat dissipation efficiency of the first cavity 21. Furthermore, the baffle fan 70 can also specifically improve the heat dissipation efficiency of a particular device within the first cavity 21. When heat dissipation is required for a specific device, the baffle fan 70 can be positioned directly over that specific device to improve its heat dissipation efficiency.

[0064] In one embodiment, the energy storage power conversion control box 100 further includes a heat sink 80, which is disposed in the second cavity 22. The IGBT circuit board 413 is disposed through the partition unit 20 and abuts against the heat sink 80.

[0065] This application also provides the following technical solutions:

[0066] An energy storage power conversion control box 100 includes: a box body 10, a partition unit 20, a power conversion unit 40, a power supply and protection unit 50, and a battery management unit 60. The box body 10 has a receiving cavity 11. The partition unit 20 is arranged in the receiving cavity 11 and includes a first plate and a second plate, dividing the receiving cavity 11 into three independent cavities: a first cavity 21, a second cavity 22, and a third cavity, along the height direction of the box body 10. The energy storage power conversion control box 100 is arranged sequentially from top to bottom along the width direction. The power conversion unit 40 includes a power conversion module 41 and a power storage module 42. The power conversion module 41 is located in the second cavity 22 and has an energy input terminal 43 and an energy output terminal 44. The power storage module 42 is located in the third cavity and is electrically connected to the energy output terminal 44. The power supply and protection unit 50 is located in the third cavity and is electrically connected to the energy input terminal 43. The battery management unit 60 is located in the first cavity 21 and is electrically connected to the power conversion module 41. This arrangement further reduces the space occupied by the energy storage power conversion control box 100 in the width and length directions of the industrial energy storage cabinet, allowing the internal space of the industrial energy storage cabinet to be adjusted according to usage requirements. This solution can be adopted when users have special needs.

[0067] This application also provides the following technical solutions:

[0068] An industrial energy storage cabinet includes an energy storage power conversion control box 100 as described in any of the above embodiments.

[0069] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0070] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
