Description

Technical Field

[0001] This application relates to the field of energy storage technology, and more specifically, to an energy storage container, an energy storage device, and a power supply system. Background Technology

[0002] Energy storage systems mainly consist of energy storage devices composed of energy storage containers and energy storage units, which are used to store and release electrical energy within the system. The interior of the energy storage container is typically divided into a battery compartment and an electrical compartment by partitions. The energy storage units are installed in the battery compartment, while the electrical compartment houses multiple electrical components, such as combiner modules and uninterruptible power supplies (UPS).

[0003] In related technologies, with the increasing use of energy storage devices, users' demand for electrical capacity is constantly increasing, thus requiring the expansion of the battery compartment to accommodate more energy storage units. However, in related technologies, the uninterruptible power supply (UPS) is fixed in the electrical compartment in a horizontal installation manner, which restricts the spatial layout within the electrical compartment and thus limits the compression of the electrical compartment, increasing the difficulty of expanding the battery compartment. Utility Model Content

[0004] A primary objective of this application is to provide an energy storage container, energy storage device, and power supply system that can optimize the spatial layout within the electrical compartment and facilitate the expansion of the battery compartment.

[0005] To achieve the above-mentioned objectives, this application adopts the following technical solution: According to one aspect of this application, an energy storage container is provided, comprising: a container body and a partition, the partition being erected in the container body and dividing the inner cavity of the container body into a battery compartment and an electrical compartment; the electrical compartment is provided with a mounting beam and a fixing frame, the fixing frame being fixed on the mounting beam and forming a receiving cavity, the receiving cavity having a dimension in the width direction of the electrical compartment being smaller than its dimension in the height direction of the electrical compartment, and the receiving cavity being used to accommodate an uninterruptible power supply.

[0006] In this embodiment, the uninterruptible power supply (UPS) is fixed in a cavity formed by the fixing frame inside the electrical compartment, ensuring the stability of the UPS assembly inside the electrical compartment. Since the dimension of the cavity in the width direction of the electrical compartment is smaller than its dimension in the height direction, the UPS can be vertically fixed, which facilitates the optimization of the spatial layout of various electrical components inside the electrical compartment, compresses the electrical compartment, effectively ensures the expansion of the battery compartment, and provides reliable support for increasing the capacity of the energy storage device.

[0007] According to one embodiment of this application, the fixing frame is located on the side of the mounting beam near the top of the electrical compartment.

[0008] In this embodiment, the mounting beam can be used to support the fixed frame, thereby supporting the uninterruptible power supply and improving the stability of the uninterruptible power supply assembly in the electrical compartment.

[0009] According to one embodiment of this application, the fixing frame includes a bottom bracket, a top bracket, and a plurality of support members; the bottom bracket is fixed on the mounting beam, the top bracket and the bottom bracket are arranged opposite each other along the height direction of the electrical compartment, the two ends of each support member are fixedly connected to the bottom bracket and the top bracket respectively, and the area between the bottom bracket and the top bracket constitutes the receiving cavity.

[0010] In this embodiment, the bottom bracket and the top bracket can be pre-assembled through multiple support members, and then the fixing efficiency of the fixing frame in the electrical compartment can be improved by fixing the bottom bracket to the mounting beam.

[0011] According to one embodiment of this application, at least one of the bottom bracket and the top bracket has a heat dissipation hole extending through the electrical compartment along its height direction.

[0012] In this embodiment, the heat dissipation area of ​​the uninterruptible power supply (UPS) can be effectively increased by setting heat dissipation holes, thereby ensuring the heat dissipation effect of the UPS. In addition, the setting of heat dissipation holes can achieve the lightweight design of the mounting bracket, thereby reducing the load requirements of the mounting beam and improving the reliability of the mounting beam in bearing the load of the mounting bracket and the UPS.

[0013] According to one embodiment of this application, the heat dissipation hole is an elongated hole, and at least one of the bottom bracket and the top bracket has a plurality of heat dissipation holes, and the length direction of the heat dissipation hole intersects with the arrangement direction of the plurality of heat dissipation holes.

[0014] According to one embodiment of this application, the electrical compartment has a compartment opening, and the bottom support has a first flap bent away from the receiving cavity at the edge facing the compartment opening, the first flap being fixedly connected to the mounting beam.

[0015] In this embodiment, the first flap allows for contact and limiting of the bottom bracket when it is fixed on the mounting beam, thereby improving the fixing efficiency of the bottom bracket on the mounting beam. Furthermore, the fixed connection between the first flap and the mounting beam avoids the need for fixing bolts on the surface of the bottom bracket facing the top bracket, thus preventing bolts from interfering with the assembly of the uninterruptible power supply (UPS) and improving the installation efficiency of the UPS on the mounting frame. Moreover, the bent first flap creates a rounded chamfer near the edge of the accommodating cavity, facilitating the guidance of the UPS and further improving its installation efficiency on the mounting frame.

[0016] According to one embodiment of this application, the top support has a second flap bent away from the receiving cavity at its edge facing the opening; the fixing frame further includes a locking member, which is fixedly connected to the second flap and is used for fixedly connecting to the uninterruptible power supply.

[0017] In this embodiment, the uninterruptible power supply (UPS) can be fixedly connected to the top bracket by setting the second flap and combining it with the locking component, thereby achieving the fixed connection of the UPS on the fixed frame and ensuring the reliability of the UPS assembly on the fixed frame.

[0018] According to one embodiment of this application, the electrical compartment has an opening, and the edge of the bottom support and / or the edge of the top support has a limiting plate bent toward the receiving cavity; the limiting plate forms a U-shape, and the U-shaped opening formed by the limiting plate faces the opening of the electrical compartment.

[0019] In this embodiment of the application, the U-shaped limiting plate formed by bending on the bottom support and / or the top support can limit the uninterruptible power supply in the width and depth directions of the electrical compartment, so as to ensure the reliability of the uninterruptible power supply in the limiting between the bottom support and the top support.

[0020] According to one embodiment of this application, the fixing frame includes two support members, which are spaced apart on the same mounting beam in the width direction of the electrical compartment, and the bottom bracket and the top bracket are both located between the two support members.

[0021] According to one embodiment of this application, the support member has a third flap that is bent away from the receiving cavity.

[0022] In this embodiment, the structural strength of the support member can be improved by bending the third flap, thereby ensuring the reliability of the support member in supporting the top bracket.

[0023] According to one embodiment of this application, the uninterruptible power supply includes a control host and a power module; the accommodating cavity has a plurality of accommodating areas distributed in the width direction of the electrical compartment, the plurality of accommodating areas being used to respectively accommodate the control host and at least one of the power modules.

[0024] According to one embodiment of this application, the partition includes a side plate disposed perpendicular to the width direction of the electrical compartment, and there is a gap between the fixing frame and the side plate.

[0025] In this embodiment, a heat dissipation channel can be formed through the air gap between the fixing frame and the side plate to optimize the heat dissipation effect of the uninterruptible power supply on the fixing frame. In addition, a door lock needs to be installed on the edge of the side plate near the compartment opening to lock the door of the electrical compartment. Based on the gap between the fixing frame and the side plate, it is easy to avoid interference between the door lock and the fixing frame, thereby ensuring the reliability of the compartment door locking.

[0026] According to one embodiment of this application, a plurality of mounting beams are provided inside the electrical compartment, the length directions of the plurality of mounting beams are parallel to each other, and the fixing frame is fixed on the plurality of mounting beams.

[0027] In this embodiment of the application, the stability of the fixing frame on the mounting beam can be ensured by multiple parallel mounting beams.

[0028] According to one embodiment of this application, the partition includes a back plate arranged parallel to the length direction of the mounting beam, and the fixing frame is fixed on the mounting beam and fixedly connected to the back plate.

[0029] In this embodiment, the stability of the fixing frame on the mounting beam can be ensured by the cooperation of the mounting beam and the back plate, while simplifying the number of mounting beams in the electrical compartment, thereby improving the space utilization rate in the electrical compartment.

[0030] According to one aspect of this application, an energy storage device is provided, the energy storage device comprising the energy storage container described in the above aspect; a plurality of energy storage units assembled in the battery compartment; and an uninterruptible power supply confined within a receiving cavity enclosed by the fixing frame.

[0047] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this application will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0048] Because the energy people need is highly time- and space-dependent, in order to make rational use of energy and improve energy efficiency, it is necessary to use a medium or device to store one form of energy in the same way or by converting it into another form of energy, and then release it in a specific form of energy based on future application needs.

[0049] Currently, the generation of green electricity generally relies on solar, wind, and hydropower. However, wind and solar power are generally characterized by strong intermittency and large fluctuations, which can cause grid instability, insufficient power during peak demand periods, and excessive power during off-peak periods. Unstable voltage can also damage the power grid. Therefore, insufficient electricity demand or insufficient grid capacity may lead to the problem of "wind and solar curtailment." Solving these problems requires energy storage. This involves converting electrical energy into other forms of energy through physical or chemical means and storing it. When needed, this energy can be converted back into electrical energy and released. Simply put, energy storage is like a large "power bank," storing electrical energy when solar and wind power are abundant and releasing the stored electricity when needed.

[0050] Taking electrochemical energy storage as an example, this solution provides an energy storage device for use in energy storage systems. The energy storage device is equipped with a set of chemical batteries, which mainly use the chemical elements in the chemical batteries as energy storage media. The charging and discharging process is accompanied by the chemical reaction or change of the energy storage media. Simply put, the electrical energy generated by wind and solar energy is stored in the chemical batteries. When the use of external electrical energy reaches its peak, the stored electricity is released for use, or transferred to places with a shortage of electricity for use.

[0051] Current energy storage applications are quite widespread, including generation-side energy storage, grid-side energy storage, and consumption-side energy storage. The corresponding types of energy storage devices include: (1) Large-scale energy storage power stations (including prefabricated energy storage modules) applied to wind power and photovoltaic power stations can help renewable energy power generation meet grid connection requirements and improve the utilization rate of renewable energy. As a high-quality active / reactive power regulation power source on the power supply side, energy storage power stations can achieve load matching of power in time and space, enhance the absorption capacity of renewable energy, reduce instantaneous power changes, reduce the impact on the power grid, improve the absorption of new energy power generation, and are of great significance in power grid system backup, alleviating peak load power supply pressure and peak regulation and frequency regulation. (2) The energy storage prefabricated cabin applied on the grid side mainly functions as peak regulation, frequency regulation and grid congestion relief. In terms of peak regulation, it can realize peak shaving and valley filling of electricity load, that is, charging the energy storage device when the electricity load is low and releasing the stored electricity during the peak period of electricity load, thereby achieving a balance between power production and consumption. (3) Small energy storage cabinets applied to the electricity consumption side mainly function as self-consumption of electricity, peak-valley price arbitrage, capacity cost management, and improvement of power supply reliability. Depending on the application scenario, electricity consumption side energy storage can be divided into industrial and commercial energy storage cabinets, household energy storage devices, energy storage charging piles, etc., which are generally used in conjunction with distributed photovoltaics. Industrial and commercial users can use energy storage for peak-valley price arbitrage and capacity cost management. In the electricity market implementing peak-valley pricing, by charging the energy storage system when the electricity price is low and discharging the energy storage system when the electricity price is high, peak-valley price arbitrage can be achieved, reducing electricity costs. In addition, industrial enterprises subject to two-part tariffs can use energy storage systems to store energy during off-peak hours and discharge during peak loads, thereby reducing peak power and the maximum demand declared, achieving the goal of reducing capacity costs. Household photovoltaics with energy storage can improve the level of self-consumption of electricity. Due to high electricity prices and poor power supply stability, the demand for household photovoltaic installations is driven. Given that photovoltaic power generation occurs during the day, while user load is generally higher at night, configuring energy storage can better utilize photovoltaic power, improve self-consumption levels, and reduce electricity costs. Furthermore, energy storage is needed in areas such as communication base stations and data centers for backup power.

[0052] Figure 1This is a schematic diagram of the structure of an energy storage system 1000 provided in this application. The energy storage system 1000 is illustrated using a shared energy storage scenario on the generation / distribution side as an example. Of course, the energy storage device 100 of this application is not limited to the shared energy storage scenario on the generation / distribution side.

[0053] like Figure 1 As shown, the energy storage system 1000 includes: an energy storage device 100, a first power conversion device 200, a second power conversion device 300, and a high-voltage cable 400.

[0054] In some embodiments of the power generation scenario, the first power conversion device 200 can be a wind power conversion device. Since the electricity generated by wind power conversion is volatile, random, and intermittent, the unstable electricity output by the wind power conversion device can be stored in an energy storage device 100 via grid connection. The energy storage device 100 is connected to the high-voltage cable 400 and outputs smooth electricity to the power consumption side, achieving peak shaving and frequency regulation, and ensuring stable grid operation. Alternatively, the wind power conversion device is always connected to the high-voltage cable 400, and under normal power generation conditions, the high-voltage cable 400... The electricity output from the wind power conversion device is supplied to the power consumption side. When the current power load is low and the wind power conversion device generates excess electricity, the excess electricity is first stored in the energy storage device 100 to improve the problem of new energy power generation and consumption. When the power load is high, the power grid issues an instruction to transmit the electricity stored in the energy storage device 100 together with the high-voltage cable 400 in grid-connected mode to supply the power consumption side. This provides the power grid with various services such as peak shaving, frequency regulation, and backup, giving full play to the peak shaving role of the power grid, promoting peak shaving and valley filling, and alleviating the power supply pressure of the power grid.

[0055] In some embodiments on the distribution network side, the second power conversion device 300 can be a photovoltaic power conversion device. The energy storage device 100 is connected to the photovoltaic power conversion device and installed downstream of the high-voltage cable 400 between the user load and the photovoltaic power conversion device. The electrical energy output by the photovoltaic power conversion device is stored in the energy storage device 100, which can respond in a timely manner to act as a backup power source when the power grid / distribution network fails. Alternatively, it can provide power supply support to alleviate line congestion when the high-voltage cable 400 transmission line is blocked, and to delay the economic pressure caused by the expansion of the power grid / distribution capacity during power grid planning and expansion.

[0056] Optionally, the first power conversion device 200 may include, but is not limited to, a wind power conversion device, and the second power conversion device 300 may include, but is not limited to, a photovoltaic panel. The first power conversion device 200 and the second power conversion device 300 can convert at least one of solar energy, light energy, wind energy, thermal energy, tidal energy, biomass energy and mechanical energy into electrical energy.

[0057] Optionally, the energy storage device 100 can be used in, but is not limited to, energy storage power stations, hydropower / thermal / wind power generation systems, solar power generation systems, mobile power systems, smart home systems, or temporary power supply systems 500, and is also applied in multiple fields such as data centers, military equipment, aerospace, charging piles, and electric vehicles.

[0058] Optionally, the energy storage device 100 may include, but is not limited to, a battery integrated system consisting of energy storage cabinets, energy storage boxes, and energy storage prefabricated compartments composed of energy storage units 20. Figure 2 (The energy storage device 100 is shown as an energy storage prefabricated compartment composed of energy storage units 20). The actual application form of the energy storage device 100 provided in this application embodiment can be, but is not limited to, the listed products, and can also be other application forms. This application embodiment does not strictly limit the application form of the energy storage device 100.

[0059] Optionally, the energy storage unit 20 may include, but is not limited to, battery modules, battery packs, etc., composed of battery cells; the battery cells are not limited to at least one of cylindrical, prismatic, prismatic, or other shaped batteries. The battery cells can be rechargeable batteries, which are battery cells that can be reactivated by charging after discharge and continue to be used. The battery cells can be lithium-ion batteries, sodium-ion batteries, sodium-lithium-ion batteries, lithium metal batteries, sodium metal batteries, lithium-sulfur batteries, magnesium-ion batteries, nickel-metal hydride batteries, nickel-cadmium batteries, lead-acid batteries, etc., and this application does not specifically limit their types.

[0060] In some implementations, such as Figure 2 As shown, the energy storage device 100 includes an energy storage container 10 and a plurality of energy storage units 20, which are assembled inside the energy storage container 10.

[0061] Among them, such as Figure 3 As shown, the energy storage container 10 includes an outer frame 31, and an installation position (not shown in the figure) is provided within the area enclosed by the outer frame 31 to realize the assembly of the energy storage unit 20 based on the installation position.

[0062] For example, such as Figure 3 As shown, the energy storage container 10 also includes a plurality of inner frames 32 disposed within the area enclosed by the outer frame 31. The plurality of inner frames 32 are spaced apart along the width direction of the energy storage container 10 (i.e., the depth direction S of the electrical compartment 30b described below), and each inner frame 32 has support positions spaced apart along the height direction of the energy storage container 10 (i.e., the height direction H of the electrical compartment 30b described below). In this way, the installation position of the energy storage unit 20 can be formed based on the support positions that are arranged opposite each other on two adjacent inner frames 32 and located at the same height, thereby realizing the assembly of the energy storage unit 20.

[0063] In some implementations, such as Figure 3 As shown, the energy storage container 10 includes a container body 30 and a partition 40. The partition 40 is erected inside the container body 30 and divides the inner cavity of the container body 30 into a battery compartment 30a and an electrical compartment 30b.

[0064] In summary, the housing 30 is the structure formed by the outer frame 31 and the inner frame 32, and the inner cavity of the housing 30 is the area enclosed by the outer frame 31. The partition 40 is erected within the area enclosed by the outer frame 31 to divide the area into a battery compartment 30a and an electrical compartment 30b. At this time, multiple inner frames 32 are installed inside the battery compartment 30a, and multiple energy storage units 20 are assembled inside the battery compartment 30a.

[0065] The battery compartment 30a and the electrical compartment 30b can be distributed along the width direction of the energy storage container 10 (i.e., the depth direction S of the electrical compartment 30b below) or along the depth direction of the energy storage container 10 (i.e., the width direction Y of the electrical compartment 30b below), that is, the electrical compartment 30b is located on the back side of the battery compartment 30a.

[0066] The energy storage device 100 includes multiple energy storage units 20, all of which are assembled within the battery compartment 30a. The energy storage device 100 also includes multiple electrical components, such as circuit breakers, fuses, and uninterruptible power supplies 50, all of which are assembled within the electrical compartment 30b. Furthermore, a high-voltage junction box can be installed within the electrical compartment 30b to establish an electrical connection between the circuit breaker and the energy storage unit 20, thereby providing high-voltage protection for the energy storage unit 20.

[0067] Additionally, a partition 40 can be installed inside the housing 30 to separate the battery compartment 30a and the electrical compartment 30b; of course, multiple partitions 40 can also be installed inside the housing 30 to divide the internal cavity of the housing 30 into, for example... Figure 3 The battery compartment 30a, electrical compartment 30b, and liquid cooling compartment 30c are shown. At this time, the electrical compartment 30b and the liquid cooling compartment 30c can be located on the same side or different sides of the battery compartment 30a in the width direction (i.e., the depth direction S of the electrical compartment 30b) of the energy storage container 10.

[0068] The liquid cooling chamber 30c is equipped with a liquid cooling system, which includes a cooling unit, a liquid storage tank, and liquid cooling pipelines connecting the liquid storage tank to the energy storage unit 20. The liquid storage tank is used to store fluid, and the cooling unit is used to circulate and cool the fluid in the liquid storage tank. The cooled fluid in the liquid storage tank can circulate along the liquid cooling pipelines to the energy storage unit 20 to cool the energy storage unit 20.

[0069] In related technologies, taking the uninterruptible power supply 50 installed in the electrical compartment 30b as an example, it is fixed by horizontal installation. This requires the partition 40 to separate the electrical compartment 30b with a large capacity within the housing 30, which undoubtedly affects the capacity of the battery compartment 30a. At the same time, with the continuous increase in the demand for electrical capacity, the horizontally installed uninterruptible power supply 50 will undoubtedly restrict the spatial layout of the various components in the electrical compartment 30b, thereby limiting the compression of the electrical compartment 30b and increasing the difficulty of expanding the capacity of the battery compartment 30a.

[0070] In the embodiments of this disclosure, such as Figure 4 and Figure 5 As shown, an installation beam 33 and a fixing frame 34 are provided inside the electrical compartment 30b. The fixing frame 34 is fixed on the installation beam 33 and forms a receiving cavity 34a. The dimension of the receiving cavity 34a in the width direction Y of the electrical compartment 30b is smaller than the dimension in the height direction H of the electrical compartment 30b. The receiving cavity 34a is used to accommodate the uninterruptible power supply 50.

[0071] Thus, the uninterruptible power supply 50 is fixed in place by the cavity 34a formed by the fixing frame 34 inside the electrical compartment 30b. That is, the uninterruptible power supply 50 can be confined within the cavity 34a formed by the fixing frame 34 to ensure the stability of the uninterruptible power supply 50 in the electrical compartment 30b. In addition, since the dimension of the cavity 34a in the width direction Y of the electrical compartment 30b is smaller than its dimension in the height direction H of the electrical compartment 30b, the uninterruptible power supply 50 is vertically fixed in the cavity 34a. That is, the height direction of the uninterruptible power supply 50 is parallel to the height direction H of the electrical compartment 30b. Based on the vertical installation of the uninterruptible power supply 50, the spatial layout of the components in the electrical compartment 30b is optimized to facilitate the compression of the electrical compartment 30b, effectively ensuring the expansion of the battery compartment 30a and providing reliable support for increasing the capacity of the energy storage device 100.

[0072] Among them, such as Figure 4 and Figure 5 As shown, the electrical compartment 30b has a compartment opening 301, a back plate 41 facing the compartment opening 301 in the depth direction S of the electrical compartment 30b, and two side plates 42 adjacent to the compartment opening 301 and arranged opposite to each other in the width direction Y of the electrical compartment 30b.

[0073] The back panel 41 of the electrical compartment 30b can be formed by a partition 40. The electrical compartment 30b has two side panels 42, one of which can be formed by a partition 40, and the other side panel 42 can be formed by a wall panel of the box body 30. In addition, the two ends of the mounting beam 33 are fixedly connected to the two side panels 42 respectively. The length direction of the mounting beam 33 can be parallel to the width direction Y of the electrical compartment 30b, or the length direction of the mounting beam 33 can be at a certain angle to the width direction Y of the electrical compartment 30b, as long as the fixing frame 34 can be fixed on the mounting beam 33.

[0074] In some implementations, such as Figure 5 As shown, the partition 40 includes a side plate 42 that is perpendicular to the width direction Y of the electrical compartment 30b, and there is a gap between the fixing frame 34 and the side plate 42.

[0075] Thus, a heat dissipation channel can be formed through the air gap between the fixing frame 34 and the side plate 42 to optimize the heat dissipation effect of the uninterruptible power supply 50 on the fixing frame 34. In addition, a door lock needs to be installed on the edge of the side plate 42 near the opening 301 to lock the door of the electrical compartment 30b. Based on the gap between the fixing frame 34 and the side plate 42, it is easy to avoid interference between the door lock and the fixing frame 34, thereby ensuring the reliability of the door locking.

[0076] In some implementations, such as Figure 6 and Figure 7 As shown, multiple mounting beams 33 are provided inside the electrical compartment 30b. The length directions of the multiple mounting beams 33 are parallel to each other, and the fixing frame 34 is fixed on the multiple mounting beams 33.

[0077] In this way, the stability of the fixing frame 34 on the mounting beam 33 can be ensured by multiple parallel mounting beams 33.

[0078] The multiple parallel mounting beams 33 can be arranged in a strictly defined parallel manner, meaning that the extensions of the multiple mounting beams 33 in the longitudinal direction do not intersect, or they can be arranged in a non-strictly defined parallel manner, meaning that the extensions of any two mounting beams 33 in the longitudinal direction intersect, and the acute angle of intersection is less than or equal to 5 degrees. Of course, the acute angle of intersection of the extensions of any two mounting beams 33 in the longitudinal direction can also be greater than 5 degrees, as long as the stability of the fixing frame 34 on the multiple mounting beams 33 can be guaranteed.

[0079] In other implementations, such as Figure 4 and Figure 5 As shown, the partition 40 inside the box 30 includes a back plate 41 arranged parallel to the length direction of the mounting beam 33, and the fixing bracket 34 is fixed on the mounting beam 33 and fixedly connected to the back plate 41.

[0080] In this way, the stability of the fixing frame 34 on the mounting beam 33 can be ensured by the cooperation between the mounting beam 33 and the back plate 41, while simplifying the number of mounting beams 33 in the electrical compartment 30b, thereby improving the space utilization rate in the electrical compartment 30b.

[0081] The fixing frame 34 and the back plate 41 can be fixedly connected by welding or by bolts. This application does not limit the connection in this respect.

[0082] In this embodiment, the mounting bracket 34 can be fixed on the side of the mounting beam 33 near the top of the electrical compartment 30b, or it can be fixed on the side of the mounting beam 33 away from the top of the electrical compartment 30b.

[0083] When the mounting bracket 34 is located on the side of the mounting beam 33 near the top of the electrical compartment 30b, the mounting beam 33 can support the mounting bracket 34 to support the uninterruptible power supply 50 and improve the stability of the uninterruptible power supply 50 in the electrical compartment 30b.

[0084] Next, we will explain in detail the example of fixing the bracket 34 to one side of the mounting beam 33 near the top of the electrical compartment 30b.

[0085] In some implementations, such as Figure 8 and Figure 9 As shown, the mounting bracket 34 includes a bottom bracket 341, a top bracket 342, and multiple support members 343. The bottom bracket 341 is fixed on the mounting beam 33. The top bracket 342 and the bottom bracket 341 are arranged opposite each other along the height direction H of the electrical compartment 30b. The two ends of each support member 343 are fixedly connected to the bottom bracket 341 and the top bracket 342 respectively, and the area between the bottom bracket 341 and the top bracket 342 forms a receiving cavity 34a.

[0086] In this way, the bottom bracket 341 and the top bracket 342 can be pre-assembled through multiple support members 343, and then the fixing efficiency of the fixing frame 34 in the electrical compartment 30b can be improved by fixing the bottom bracket 341 to the mounting beam 33.

[0087] The support member 343 has a certain length along the height direction H of the electrical compartment 30b, so that after the top bracket 342 and the support member 343 are fixed, a receiving cavity 34a can be formed between the top bracket 342 and the bottom bracket 341. The support member 343 can be a strip-shaped flat plate structure or a square beam structure, as long as it can achieve a fixed connection with the mounting beam 33 and the top bracket 342. For example, such as Figure 9As shown, the support member 343 has a third flap 348 bent away from the receiving cavity 34a, so as to improve the structural strength of the support member 343 by bending the third flap 348, thereby ensuring the reliability of the support member 343 in supporting the top bracket 342.

[0088] Furthermore, the number of support members 343 can be two, three, four, etc. For example, if there are two support members 343, then the two support members 343 are spaced apart on the same mounting beam 33 in the width direction Y of the electrical compartment 30b, and the bottom bracket 341 and the top bracket 342 are both located between the two support members 343. In this way, only one mounting beam 33 needs to be set in the electrical compartment 30b, thus saving the number of mounting beams 33. At the same time, when the uninterruptible power supply 50 is installed on the fixing frame 34, mutual interference between the two support members 343 and the uninterruptible power supply 50 can be avoided.

[0089] Of course, for the two support members 343 included in the fixing frame 34, when two mounting beams 33 are provided in the electrical compartment 30b along the depth direction of the electrical compartment 30b, the two support members 343 can be provided on the same mounting beam 33, or the two support members 343 can be distributed on the two mounting beams 33 respectively along the depth direction of the electrical compartment 30b. In this case, in the width direction of the electrical compartment 30b, the bottom bracket 341 and the top bracket 342 can be located on the same side of the two support members 343, or they can be located between the two support members 343. The embodiments of this application do not limit this.

[0090] It should be noted that, in addition to setting the support member 343 to support the top bracket 342, a suspension beam can also be set in the electrical compartment 30b. The suspension beam is located on the side of the top bracket 342 away from the bottom bracket 341. In this case, the fixed connection between the top bracket 342 and the suspension beam can form an accommodating cavity 34a between the bottom bracket 341 and the top bracket 342.

[0091] In some implementations, such as Figure 9 As shown, at least one of the bottom bracket 341 and the top bracket 342 has a heat dissipation hole 344 extending through the electrical compartment 30b in the height direction H.

[0092] In this way, the heat dissipation area of ​​the uninterruptible power supply 50 can be effectively increased by setting the heat dissipation hole 344, thereby ensuring the heat dissipation effect of the uninterruptible power supply 50. In addition, the setting of the heat dissipation hole 344 can realize the lightweight setting of the fixing frame 34, thereby reducing the load requirement of the mounting beam 33, while improving the reliability of the mounting beam 33 in supporting the fixing frame 34 and the uninterruptible power supply 50.

[0093] The bottom bracket 341 may have a heat dissipation hole 344 extending through the electrical compartment 30b along the height direction H; the top bracket 342 may have a heat dissipation hole 344 extending through the electrical compartment 30b along the height direction H; or both the bottom bracket 341 and the top bracket 342 may have a heat dissipation hole 344 extending through the electrical compartment 30b along the height direction H. The heat dissipation holes 344 on the bottom bracket 341 and / or the top bracket 342 may be arrayed through holes, each of which may be a round hole, a triangular hole, a rectangular hole, a diamond-shaped hole, etc.

[0094] Of course, ventilation holes 344 can also be like this. Figure 9 As shown in the diagram, at least one of the bottom bracket 341 and the top bracket 342 has multiple heat dissipation holes 344, and the length direction of the heat dissipation holes 344 intersects with the arrangement direction of the multiple heat dissipation holes 344. Thus, by providing elongated holes on the bottom bracket 341 and / or the top bracket 342, the exposed area of ​​the uninterruptible power supply 50 at the heat dissipation holes 344 can be effectively increased, thereby effectively increasing the heat dissipation effect of the uninterruptible power supply 50.

[0095] For example, such as Figure 9 As shown, both the bottom bracket 341 and the top bracket 342 have heat dissipation holes 344 (elongated holes) whose length direction is parallel to the depth direction S of the electrical compartment 30b, and three heat dissipation holes 344 are distributed at intervals along the width direction Y of the electrical compartment 30b.

[0096] In some implementations, such as Figure 8 and Figure 9 As shown, the electrical compartment 30b has a compartment opening 301, and the bottom support 341 has a first flap 345 bent away from the receiving cavity 34a on the edge facing the compartment opening 301. The first flap 345 is fixedly connected to the mounting beam 33.

[0097] Thus, by setting the first flap 345, when fixing the bottom bracket 341 on the mounting beam 33, the first flap 345 can achieve the contact limit between the two, thereby improving the fixing efficiency of the bottom bracket 341 on the mounting beam 33. In addition, by fixing the first flap 345 to the mounting beam 33, it is possible to avoid setting fixing bolts on the surface of the bottom bracket 341 facing the top bracket 342 to fix it to the mounting beam 33, thereby avoiding the fixing bolts interfering with the assembly of the uninterruptible power supply 50, which facilitates the improvement of the installation efficiency of the uninterruptible power supply 50 on the mounting frame 34. Furthermore, based on the bent first flap 345, an arc chamfer can be formed on the edge of the first flap 345 near the receiving cavity 34a, thereby facilitating the guidance of the uninterruptible power supply 50, thereby improving the installation efficiency of the uninterruptible power supply 50 on the mounting frame 34.

[0098] The first flap 345 is an integrally bent structure at the edge of the bottom support 341 facing the opening 301, so as to improve the structural strength of the bottom support 341 and thus ensure the support effect for the uninterruptible power supply 50. The first flap 345 and the mounting beam 33 can be fixedly connected by welding or by fixing bolts.

[0099] In some implementations, such as Figure 10 and Figure 11 As shown, the top bracket 342 has a second flap 346 bent away from the receiving cavity 34a on the edge facing the opening 301; the fixing frame 34 also includes a locking member 349, which is fixedly connected to the second flap 346 and is used to fixally connect to the uninterruptible power supply 50.

[0100] Thus, the uninterruptible power supply 50 can be fixedly connected to the top bracket 342 by setting the second flap 346 and combining it with the locking part 349, thereby achieving the fixed connection of the uninterruptible power supply 50 on the fixed frame 34 and ensuring the reliability of the uninterruptible power supply 50 assembly on the fixed frame 34.

[0101] The second flap 346 is an integrally bent structure on the edge of the top support 342 facing the opening 301, so as to improve the structural strength of the top support 342. The second flap 346 and the locking part can be fixedly connected by welding or by fixing bolts.

[0102] In some implementations, such as Figure 9 or Figure 11 As shown, the electrical compartment 30b has a compartment opening 301, and the edges of the bottom support 341 and / or the top support 342 have limiting plates 347 bent toward the receiving cavity 34a; the limiting plates 347 form a U-shape, and the U-shaped opening formed by the limiting plates 347 faces the compartment opening 301 of the electrical compartment 30b.

[0103] Thus, the U-shaped limiting plate 347 formed by bending on the bottom support 341 and / or the top support 342 can limit the uninterruptible power supply 50 in the width direction Y and depth direction S of the electrical compartment 30b, so as to ensure the reliability of the uninterruptible power supply 50 in the limiting position between the bottom support 341 and the top support 342.

[0104] The bottom support 341 may have a U-shaped limiting plate 347 bent toward the receiving cavity 34a at its edge, or the top support 342 may have a U-shaped limiting plate 347 bent toward the receiving cavity 34a at its edge, or both the bottom support 341 and the top support 342 may have a U-shaped limiting plate 347 bent toward the receiving cavity 34a at their edges.

[0105] When both the edge of the bottom bracket 341 and the edge of the top bracket 342 have U-shaped limiting plates 347, a heat dissipation window is formed between the two U-shaped limiting plates 347 in the height direction H of the electrical compartment 30b. Based on the heat dissipation window between the two U-shaped limiting plates 347, the side wall of the uninterruptible power supply 50 is directly exposed, thereby ensuring the heat dissipation effect of the uninterruptible power supply 50.

[0106] For example, the bottom support 341 has a U-shaped limiting plate 347 on its edge. The bottom support 341 may have three flaps facing the accommodating cavity 34a on its remaining three edges, excluding the edge facing the opening 301. The flaps on the three edges are then welded and fixed to form the U-shaped limiting plate 347.

[0107] In some implementations, such as Figure 5 and Figure 7 As shown, the uninterruptible power supply 50 includes a control host 51 and a power module 52. The accommodating cavity 34a has a plurality of accommodating areas 34b distributed in the width direction Y of the electrical compartment 30b. The plurality of accommodating areas 34b are used to respectively accommodate the control host 51 and at least one power module 52.

[0108] Thus, by using the multiple accommodating areas 34b of the accommodating cavity 34a, the control host 51 and the power module 52 are positioned vertically within the accommodating cavity 34a, so as to optimize the spatial layout of the various components in the electrical compartment 30b.

[0109] The uninterruptible power supply 50 may include one or more power modules 52, such as two; correspondingly, the accommodating cavity 34a may have two or at least three accommodating areas 34b. In this case, the control host 51 included in the uninterruptible power supply 50 may be limited to a corresponding accommodating area 34b, and one or more power modules 52 may be limited to a corresponding accommodating area 34b, thereby realizing the assembly of the uninterruptible power supply 50 within the accommodating cavity 34a.

[0110] The multiple accommodating areas 34b of the accommodating cavity 34a can be arranged adjacent to each other, in which case the control host 51 and the power module 52 are fitted and limited within the accommodating cavity 34a. Of course, the multiple accommodating areas 34b of the accommodating cavity 34a can also be distributed at intervals. For example, the cavity wall of the accommodating cavity 34a on the fixing frame 34 has an isolation block located between two adjacent accommodating areas 34b, so that the multiple accommodating areas 34b can be separated by the isolation block, thereby ensuring that there is an air gap between the control host 51 and the adjacent power module 52, and between two adjacent power modules 52, so as to ensure the heat dissipation effect of the control host 51 and the power module 52 through the air gap.

[0111] This application also provides a power supply system 500, such as... Figure 12As shown, the power supply system 500 includes: electrical equipment 510 and the energy storage device 100 described in the above embodiments, the energy storage device 100 being used to supply power to the electrical equipment 510.

Thus, in conjunction with the above description, the power supply system 500 of this application, during use, ensures the reliability of the power supply from the energy storage device 100 to the electrical equipment 510 due to the high assembly efficiency of the energy storage device 100.
