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 comprised of energy storage containers and energy storage units, enabling the storage and release of electrical energy within the system. The internal cavity of the energy storage container is typically divided into a battery compartment and an electrical compartment by partitions. The energy storage units are assembled in the battery compartment, while the electrical compartment houses multiple electrical components, such as control circuits, bus switches, and power supplies. In related technologies, these components are usually integrated within the electrical compartment, with each component functioning as a separate bus control cabinet, directly fixed inside. This not only increases the design complexity but also the maintenance complexity of the individual components. Utility Model Content

[0003] A primary objective of this application is to provide an energy storage container, energy storage device, and power supply system that can improve the assembly and maintenance efficiency of various components within an electrical compartment.

[0004] 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, including a container body and a partition, the partition being erected inside the container body and dividing the interior of the container body into a battery compartment and an electrical compartment; the electrical compartment is provided with a fixing bracket and has a first fixing area located near the top of the electrical compartment on the fixing bracket, the fixing bracket including at least a first fixing frame and a second fixing frame, the first fixing frame and the second fixing frame being distributed along the height direction of the electrical compartment, the first fixing area being used to fix a power distribution cabinet, the first fixing frame being used to fix at least a busbar switch, and the second fixing frame being used to fix at least an uninterruptible power supply.

[0005] In this embodiment, the distribution cabinet, busbar switch, and power supply unit can be individually fixed in the electrical compartment by setting up a fixed bracket and a first fixed area. This not only simplifies the fixing design of the distribution cabinet, busbar switch, and power supply unit in the electrical compartment, but also facilitates the individual maintenance of the distribution cabinet, busbar switch, and power supply unit, thereby improving the maintenance efficiency of electrical components in the electrical compartment and ensuring the reliability of the energy storage device's charging and discharging.

[0006] According to one embodiment of this application, the partition has a wiring hole near the bottom of the electrical compartment, and the first fixing bracket is located on the side of the second fixing bracket near the bottom of the electrical compartment.

[0007] In this embodiment of the application, based on the adjustment of the position of the wiring hole on the partition and the adjustment of the position of the first fixing bracket, the bus switch and the wiring hole can be set up close to each other. This can shorten the length of the connecting wires (such as high voltage wires) that are led out from the bus switch and extended to the battery compartment, thereby saving the space occupied by the connecting wires in the electrical compartment and reducing or even avoiding interference between the connecting wires and other wire harnesses.

[0008] According to one embodiment of this application, the first fixing frame has a fixing surface facing the top of the electrical compartment, and the orthographic projection of the fixing surface on the partition is located directly above the wiring hole; the first fixing frame and the bottom of the battery compartment form an accommodating space, and a busbar is fixed in the accommodating space.

[0009] In this embodiment, the orthographic projection of the fixing surface of the first fixing frame onto the partition is located directly above the wiring hole, making the wiring lead-out side of the bus switch closer to the wiring hole, thereby further shortening the length of the connecting wire in the electrical compartment. At the same time, the accommodating space enclosed by the first fixing frame and the bottom of the electrical compartment facilitates the alignment of the accommodating space with the wiring hole on the partition. Consequently, for the busbar installed in the accommodating space, it is easy to ensure that the connecting wire on the busbar extends in a straight line to the position of the wiring hole. On the basis of shortening the length of the connecting wire in the electrical compartment, the bending of the connecting wire in the electrical compartment is reduced or even avoided.

[0010] According to one embodiment of this application, the first fixing frame has a first fixing position and a second fixing position distributed along the width direction of the electrical compartment, the first fixing position being used to fix the bus switch, and the second fixing position being used to fix the fuse.

[0011] In this embodiment of the application, by combining the setting of the first fixed position and the second fixed position, the bus switch and the fuse can be integrated and fixed, thereby shortening the distance between the bus switch and the fuse, and further shortening the length of the connecting wire between the bus switch and the fuse, so as to save the space occupied by the connecting wire in the electrical compartment.

[0012] According to one embodiment of this application, the first fixing frame supports and is fixed to the bottom of the electrical compartment, and the second fixing frame supports and is fixed to the first fixing frame.

[0013] In this embodiment, the first and second fixed frames can be pre-fixed to simplify the assembly of the fixed brackets in the electrical compartment, thereby facilitating the improvement of the assembly efficiency of the energy storage container.

[0014] According to one embodiment of this application, at least one of the first fixing frame and the second fixing frame includes a guide rail bracket and a tray; the guide rail bracket is fixed inside the electrical compartment, and the tray is detachably fixed to the guide rail bracket.

[0015] In this embodiment, based on the detachable arrangement of the tray and the guide rail bracket, the bus switch can be pre-fixed on the tray, and then the tray can be fixed on the guide rail bracket based on the sliding fit between the tray and the guide rail bracket, so as to avoid interference between the bus switch and the second fixing bracket, while simplifying the assembly and fixing of the bus switch and improving assembly efficiency.

[0016] According to one embodiment of this application, a first support member is further provided inside the electrical compartment. The first support member is located on the side of the fixed bracket near the top of the battery compartment, and the first support member is used to support the power distribution cabinet.

[0017] In this embodiment, a first fixed area can be formed by the area of ​​the first support member near the top of the electrical compartment, thereby enabling the distribution cabinet to be fixed in the first fixed area while the first support member provides support for the distribution cabinet, ensuring the stability of the distribution cabinet within the electrical compartment.

[0018] According to one embodiment of this application, the electrical compartment has a first compartment wall and a second compartment wall disposed opposite to each other along the width direction of the electrical compartment; the fixing bracket is disposed adjacent to the first compartment wall, and a second fixing area is provided between the fixing bracket and the second compartment wall, the second fixing area being used to fix the fire tank.

[0019] In this embodiment, the space inside the electrical compartment is rationally utilized by fixing the components close to the first compartment wall, thereby saving the space for fixing the fire tank in the second fixing area. At the same time, the separate fixing of the fire tank in the electrical compartment further simplifies the fixing of components in the electrical compartment and facilitates the maintenance of the independently fixed components, thereby improving maintenance efficiency.

[0020] According to one embodiment of this application, a second support member is further provided inside the electrical compartment. The second support member is located between the fixed bracket and the second compartment wall, and the second support member is used to support the fire tank.

[0021] In this embodiment, a second fixing area can be formed in the region near the top of the electrical compartment by the second support member, thereby enabling the fire tank to be fixed in the second fixing area while the fire tank is supported by the second support member, ensuring the stability of the fire tank in the electrical compartment.

[0022] According to one embodiment of this application, the first fixing frame supports and is fixed to the bottom of the electrical compartment, and the second fixing frame is supported on the second support member and is fixedly connected to the side wall of the first fixing frame.

[0023] In this embodiment of the application, the second fixed frame is fixedly connected to the first fixed frame, and the second fixed frame is supported on the second support member, so as to ensure the stability of the second fixed frame and thus ensure the reliability of the second fixed frame in supporting the power supply host.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] Figure 1 This 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] Among them, such as Figure 3 As shown, the energy storage container 10 includes an outer frame 31, and an installation position 33 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 33.

[0053] For example, such as Figure 3 As shown, the area enclosed by the outer frame 31 can be provided with multiple inner frames 32. The multiple inner frames 32 are distributed at intervals along the width direction of the energy storage container 10 (i.e., the depth direction S of the electrical compartment 30b below). Each inner frame 32 has support positions 34 distributed at intervals along the height direction of the energy storage container 10 (i.e., the height direction H of the electrical compartment 30b below). In this way, the mounting position 33 of the energy storage unit 20 can be formed based on the support positions 34 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.

[0054] In some implementations, such as Figure 4 As shown, the inner frame 32 includes multiple connecting vertical beams 321 and multiple connecting horizontal beams 322. The multiple connecting vertical beams 321 are distributed at intervals along the depth direction of the energy storage container 10 (i.e., the width direction Y of the electrical compartment 30b below), and the multiple connecting horizontal beams 322 are distributed at intervals along the height direction of the energy storage container 10 (i.e., the height direction H of the electrical compartment 30b below). Each connecting horizontal beam 322 is fixedly connected to the multiple connecting vertical beams 321.

[0055] The connecting beam 322 can be a square tube beam or a beam structure with an L-shaped end face, as long as it can achieve a fixed connection of multiple connecting vertical beams 321. Each connecting beam 322 can be fixedly connected to two, three, or all of the connecting vertical beams 321. In addition, the connecting beam 322 can also have a support surface facing the top frame 312 to form a support position 34 for the energy storage unit 20, thereby realizing the reuse of the connecting beam 322 and simplifying the structure of the inner frame 32. Furthermore, when the connecting beam 322 has a support position 34, the plurality of inner frames 32 include the outermost inner frame 32 located in the width direction of the energy storage container 10 (i.e., the depth direction S of the electrical compartment 30b below), and all the connecting beams 322 included in the outermost inner frame 32 are fixed on one side of the connecting vertical beam 321 close to an adjacent inner frame 32; except for the outermost inner frame 32, all the connecting beams 322 included in the remaining inner frames 32 are fixed on both sides of the connecting vertical beam 1 along the width direction of the energy storage container 10 (i.e., the depth direction S of the electrical compartment 30b below).

[0056] In some implementations, such as Figure 4 As shown, the inner frame 32 also includes multiple connecting inclined beams 323, each of which is fixedly connected to multiple connecting vertical beams 321.

[0057] Thus, by reinforcing the connection between the inclined beams 323 and the multiple vertical beams 321, the structural strength of the inner frame 32 is further improved. At the same time, the setting of the inclined beams 323 facilitates the structural stability of the energy storage container 10 when hoisting it.

[0058] To avoid interference with the fixed connection between the connecting crossbeam 322 and the connecting vertical beam 321, the dimension of the connecting inclined beam 323 in the width direction of the energy storage container 10 (i.e., the depth direction S of the electrical compartment 30b below) is smaller than or equal to the dimension of the connecting vertical beam 321. Furthermore, the cross-sectional area of ​​the connecting inclined beam 323 can be set to be greater than or equal to the cross-sectional area of ​​the connecting vertical beam 321. This ensures that the structural strength of the connecting inclined beam 323 is greater than that of the connecting vertical beam 321. Consequently, when hoisting the energy storage container 10, since the hoisting position is located at one of the four corners of the energy storage container 10, the energy storage container 10 experiences a force that causes it to deform towards the center. At this time, based on the length direction of the connecting inclined beam 323, the connecting inclined beam 323 is simultaneously subjected to a force along the height direction of the energy storage container 10 (i.e., the height direction H of the electrical compartment 30b below) and a force along the depth direction of the energy storage container 10 (i.e., the width direction Y of the electrical compartment 30b below). Therefore, based on the structural strength of the connecting inclined beam 323, complete deformation is avoided. The cross-sections of the connecting inclined beam 323 and the connecting vertical beam 321 are both perpendicular to their own length direction.

[0059] In some implementations, such as Figure 3 or Figure 5 As shown, the outer frame 31 includes a bottom frame 311 and a top frame 312 arranged opposite to each other, and a plurality of columns 313 connecting the bottom frame 311 and the top frame 312.

[0060] The energy storage container 10 also includes a bottom plate fixed to the bottom frame 311, a top plate fixed to the top frame 312, and a cabinet door and side panels fixed between the bottom frame 311 and the top frame 312. The side panels of the energy storage container 10 include a back panel disposed opposite to the cabinet door along the depth direction of the energy storage container 10 (i.e., the width direction Y of the electrical compartment 30b described below), and a side end panel located between the cabinet door and the back panel. Furthermore, the mounting positions 33 within the area enclosed by the outer frame 31 are exposed when the cabinet door is opened, thereby facilitating the assembly, disassembly, and maintenance of the energy storage unit 20 by personnel at the mounting positions 33 after the cabinet door is opened.

[0061] As described above, the inner frame 32 is fixedly connected between the bottom frame 311 and the top frame 312. Specifically, each connecting vertical beam 321 within the inner frame 32 is fixedly connected at both ends to the bottom frame 311 and the top frame 312, thereby ensuring the structural stability of the outer frame 31 by combining multiple columns 313 and multiple inner frames 32. The bottom frame 311 and the top frame 312 of the outer frame 31 can have the same or different structures. The following explanation will focus on the bottom frame 311 as an example.

[0062] In some embodiments, the bottom frame 311 includes a front bottom crossbeam, a rear bottom crossbeam, and a pair of bottom longitudinal beams that form a rectangular frame, as well as a support crossbeam connected to the pair of bottom longitudinal beams within the rectangular frame.

[0063] Thus, based on the rectangular frame formed by the front bottom crossbeam, the rear bottom crossbeam, and a pair of bottom longitudinal beams, the support beams connected to the pair of bottom longitudinal beams achieve support within the area of ​​the rectangular frame, thereby improving the structural strength of the bottom frame 311 and thus improving the structural strength of the outer frame 31, ensuring the load-bearing effect of the energy storage container 10 on multiple energy storage units 20.

[0064] The length direction of the supporting beam is the width direction of the energy storage container 10 (i.e., the depth direction S of the electrical compartment 30b described below). Combined with the multiple inner frames 32 set above, the supporting beam can support the multiple inner frames 32, thereby ensuring the stability of the multiple inner frames 32 within the area enclosed by the outer frame 31.

[0065] Furthermore, the front and rear bottom crossbeams of the bottom frame 311 can be distinguished based on the location of the cabinet doors included in the energy storage container 10. Specifically, the bottom frame 311 includes a pair of bottom crossbeams arranged parallel to the supporting crossbeams, with the bottom crossbeam closer to the cabinet door being the front bottom crossbeam and the bottom crossbeam farther from the cabinet door being the rear bottom crossbeam.

[0066] In some implementations, the distance from the support beam to the front bottom beam is less than the distance to the rear bottom beam.

[0067] Thus, with the bottom frame 311 and top frame 312 having backplate support on the side near the rear bottom crossbeam, the support crossbeam is adjusted to be relatively close to the front bottom crossbeam, that is, the support crossbeam is adjusted to be set closer to the cabinet door. Based on the support of the inner frame 32 between the support crossbeam and the top frame 312, the structural strength of the outer frame 31 on the side near the cabinet door is guaranteed, thereby ensuring the load-bearing effect of the energy storage container 10 on multiple energy storage units 20.

[0068] In the case where the distance from the supporting beam to the front bottom beam is less than the distance to the rear bottom beam, in conjunction with the connecting inclined beams 323 included in the inner frame 32, in order to ensure the balance of structural strength of the outer frame 31 on both sides of the supporting beam, the multiple connecting inclined beams 323 can be designed asymmetrically on both sides of the supporting beam. That is, all the connecting inclined beams 323 located on the side of the supporting beam closer to the front bottom beam and all the connecting inclined beams 323 located on the side of the supporting beam closer to the rear bottom beam are asymmetrical structures.

[0069] In some embodiments, the bottom frame 311 also includes a plurality of supporting longitudinal beams connected between the rear bottom crossbeam and the front bottom crossbeam, and the plurality of supporting longitudinal beams are fixedly connected to the supporting crossbeams.

[0070] Thus, by setting up the supporting longitudinal beams, the structure of the bottom frame 311 is reinforced, the structural strength of the outer frame 31 is further improved, and the load-bearing effect of the energy storage container 10 on multiple energy storage units 20 is guaranteed.

[0071] In this configuration, multiple inner frames 32 are combined with multiple supporting longitudinal beams that correspond one-to-one with the multiple inner frames 32, so that each inner frame 32 is supported on the supporting crossbeam while also being supported on the corresponding supporting longitudinal beam, thereby ensuring the reliability of the bottom frame 311 in supporting the multiple inner frames 32.

[0072] In some implementations, such as Figure 3 and Figure 5 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.

[0073] The housing 30 is the structure composed of the outer frame 31, inner frame 32, bottom plate, top plate, cabinet door and side plate, as described above; the partition 40 is fixed between the bottom frame 311 and the top frame 312 to divide the area enclosed by the outer frame 31 into battery compartment 30a and electrical compartment 30b.

[0074] 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), meaning the electrical compartment 30b is located on the back side of the battery compartment 30a. The battery compartment 30a is used to assemble multiple energy storage units 20, and the electrical compartment 30b is used to assemble multiple electrical components (such as a bus switch 3014 (i.e., a circuit breaker), a fuse 3017, a power supply unit 3015, a power distribution module 3018, etc.). Additionally, as... Figure 5 and Figure 6 As shown, the partition 40 (such as the back plate of the electrical compartment 30b) has a wiring hole 41 that connects the battery compartment 30a (not shown in the figure) and the electrical compartment 30b, so that the wiring 303 can pass through the wiring hole 41 to realize the electrical connection between the energy storage unit 20 (not shown in the figure) and electrical devices (such as the bus switch 3014, etc.).

[0075] Additionally, a partition 40 can be installed inside the housing 30 to separate the battery compartment 30a and the electrical compartment 30b; in this case, various electrical components, as well as components related to the liquid cooling system, can be installed in the electrical compartment 30b. Of course, as... Figure 3 and Figure 5 As shown, multiple partitions 40 can also be provided inside the container 30 to divide the interior of the container 30 into a battery compartment 30a, an electrical compartment 30b, and a cooling compartment 30c. In this case, the electrical compartment 30b and the 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.

[0076] The 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.

[0077] For the multiple electrical components assembled within the electrical compartment 30b, relevant technologies typically involve the integrated assembly of the bus switch 3014, power supply unit 3015, and distribution box, etc., that is, integrating the bus switch 3014, power supply unit 3015, and distribution box into a single bus switch cabinet, which is then fixed within the electrical compartment 30b. However, this integrated bus switch cabinet not only increases the design complexity but also the maintenance complexity of each electrical component.

[0078] In the embodiments of this disclosure, such as Figure 5 and Figure 6 As shown, a fixed bracket 50 is provided inside the electrical compartment 30b, and a first fixed area 3011 is located on the fixed bracket 50 near the top of the electrical compartment 30b. The fixed bracket 50 includes at least a first fixed frame 51 and a second fixed frame 52. The first fixed frame 51 and the second fixed frame 52 are distributed along the height direction H of the electrical compartment 30b. The first fixed area 3011 is used to fix the distribution cabinet 3013. The first fixed frame 51 is used to fix at least the bus switch 3014. The second fixed frame 52 is used to fix at least the uninterruptible power supply.

[0079] Thus, by setting up the fixed bracket 50 and the first fixed area 3011, the distribution cabinet 3013, the bus switch 3014, and the power supply unit 3015 can be individually fixed in the electrical compartment 30b. This not only simplifies the fixing design of the distribution cabinet 3013, the bus switch 3014, and the power supply unit 3015 in the electrical compartment 30b, but also facilitates individual maintenance of the distribution cabinet 3013, the bus switch 3014, and the power supply unit 3015, thereby improving the maintenance efficiency of electrical components in the electrical compartment 30b and ensuring the reliability of the energy storage device 100's charging and discharging. In addition, the individually fixed distribution cabinet 3013, the bus switch 3014, and the power supply unit 3015 can achieve electrical isolation to prevent electrical breakdown and electromagnetic interference between different potentials, thereby effectively reducing the risk of short circuits and signal interference.

[0080] Specifically, the first fixed area 3011 within the electrical compartment 30b can be the area on the back panel of the electrical compartment 30b located on the side of the fixed bracket 50 near the top of the electrical compartment 30b. In this case, the fixed assembly of the distribution cabinet 3013 in the first fixed area 3011 is the fixing of the distribution cabinet 3013 on the back panel of the electrical compartment 30b, and the fixed distribution cabinet 3013 is located on the side of the fixed bracket 50 near the top of the electrical compartment 30b.

[0081] The fixed bracket 50 includes a first fixed frame 51 and a second fixed frame 52, which can be fixed separately in the electrical compartment 30b, while ensuring that the first fixed frame 51 and the second fixed frame 52 are stacked along the height direction H of the electrical compartment 30b. Alternatively, the first fixed frame 51 and the second fixed frame 52 can be fixedly connected to each other, while ensuring that the first fixed frame 51 and the second fixed frame 52 are stacked along the height direction of the electrical compartment 30b, and then fixed as a whole in the electrical compartment 30b.

[0082] When the first fixing frame 51 and the second fixing frame 52 are pre-fixed, it simplifies the assembly of the fixing bracket 50 within the electrical compartment 30b, thereby improving the assembly efficiency of the energy storage container 10. For example, as... Figure 6 As shown, the first fixing frame 51 is supported and fixed to the bottom of the electrical compartment 30b, and the second fixing frame 52 is supported and fixed to the first fixing frame 51; or the second fixing frame 52 is supported and fixed to the bottom of the electrical compartment 30b, and the first fixing frame 51 is supported and fixed to the second fixing frame 52.

[0083] The first fixing bracket 51 can be used to fix the bus switch 3014 alone, that is, the first fixing bracket 51 has only one fixing position, and this fixing position is used to fix the bus switch 3014; of course, it can also be as follows: Figure 6 As shown, the first fixing frame 51 has a first fixing position 513 and a second fixing position 514 distributed along the width direction Y of the electrical compartment 30b. The first fixing position 513 is used to fix the bus switch 3014, and the second fixing position 514 is used to fix the fuse 3017.

[0084] When the first fixing bracket 51 has a first fixing position 513 and a second fixing position 514, it can realize the integrated fixing of the bus switch 3014 and the fuse 3017, thereby shortening the distance between the bus switch 3014 and the fuse 3017, and further shortening the length of the connecting wire between the bus switch 3014 and the fuse 3017, so as to save the space occupied by the connecting wire in the electrical compartment 30b.

[0085] Additionally, the second mounting bracket 52 can be used to fix the power supply unit 3015 separately, that is, the second mounting bracket 52 has only one fixing position, and this fixing position is used to fix the power supply unit 3015; of course, it can also be as follows: Figure 6 As shown, the second mounting bracket 52 has a third mounting position 521 and a fourth mounting position 522 distributed along the width direction Y of the electrical compartment 30b. The third mounting position 521 is used to fix the power supply host 3015, and the fourth mounting position 522 is used to fix the power distribution module 3018.

[0086] When the second fixing frame 52 has the third fixing position 521 and the fourth fixing position 522, it can realize the integrated fixing of the power supply host 3015 and the power distribution module 3018, thereby shortening the distance between the power supply host 3015 and the power distribution module 3018, and further shortening the length of the connecting line between the power supply host 3015 and the power distribution module 3018, so as to save the space occupied by the connecting line in the electrical compartment 30b.

[0087] In addition, the specific structure of the first fixing frame 51 can be as follows: Figure 6 As shown, the first fixing frame 51 includes a support frame 515 and a bearing plate 516. The support frame 515 is fixed inside the electrical compartment 30b, and the bearing plate 516 is fixed on the support frame. The bearing plate 516 is used to support and fix the bus switch 3014. Alternatively, the first fixing frame 51 may include a guide rail bracket 523 and a tray 524. The guide rail bracket 523 is fixed inside the electrical compartment 30b, and the tray 524 is detachably fixed on the guide rail bracket 523. Of course, the first fixing frame 51 can also have other structures, as long as it can ensure the assembly of the bus switch 3014 on the first fixing frame 51. This application does not limit this aspect.

[0088] Taking the second fixing frame 52 located on the side of the first fixing frame 51 near the top of the electrical compartment 30b as an example, when the first fixing frame 51 includes a support frame 515 and a bearing plate 516, the bus switch 3014 can be fixed on the bearing plate 516 in advance, and then the second fixing frame 52 can be fixed on the first fixing frame 51, thereby avoiding interference between the bus switch 3014 and the second fixing frame 52, simplifying the assembly and fixing of the bus switch 3014, and improving assembly efficiency.

[0089] When the first fixing frame 51 includes a guide rail bracket 523 and a tray 524, the bus switch 3014 can be pre-fixed on the tray 524 due to the detachable arrangement of the tray 524 and the guide rail bracket 523. Then, based on the sliding fit between the tray 524 and the guide rail bracket 523, the tray 524 is fixed on the guide rail bracket 523, thereby avoiding interference between the bus switch 3014 and the second fixing frame 52, simplifying the assembly and fixing of the bus switch 3014, and improving assembly efficiency.

[0090] It should be noted that the structure of the second fixing frame 52 can be the same as or different from that of the first fixing frame 51, as long as the first fixing frame 51 and the second fixing frame 52 can be stacked within the electrical compartment 30b, while ensuring the fixation of the bus switch 3014 and the power supply unit 3015. For example, at least one of the first fixing frame 51 and the second fixing frame 52 includes a guide rail bracket 523 and a tray 524. The guide rail bracket 523 is fixed within the electrical compartment 30b, and the tray 524 is detachably fixed to the guide rail bracket 523. Figure 6As shown, the second mounting bracket 52 includes a guide rail bracket 523 and a tray 524. The guide rail bracket 523 is fixed inside the electrical compartment 30b, and the tray 524 is detachably fixed to the guide rail bracket 523.

[0091] In some implementations, such as Figure 6 As shown, the partition 40 (i.e., the back plate of the electrical compartment 30b) has a wiring hole 41 near the bottom of the electrical compartment 30b, and the fixing bracket 50 includes a first fixing bracket 51 located on the side of the second fixing bracket 52 near the bottom of the electrical compartment 30b.

[0092] Thus, based on the position adjustment of the wiring hole 41 on the partition 40 and the position adjustment of the first fixing bracket 51, the bus switch 3014 and the wiring hole 41 can be set up close to each other. This can shorten the length of the connecting wire 303 (such as high voltage wire) that leads out of the bus switch 3014 and extends to the battery compartment 30a in the electrical compartment 30b, thereby saving the space occupied by the connecting wire 303 in the electrical compartment 30b, and reducing or even avoiding interference between the connecting wire 303 and other wire harnesses.

[0093] The first fixing frame 51 has a fixing surface 511 facing the top of the electrical compartment 30b (which can also be said to be a bearing surface for supporting the bus switch 3014). At this time, the orthographic projection of the fixing surface 511 of the first fixing frame 51 on the partition 40 (such as the back plate of the electrical compartment 30b) can be located directly above the wiring hole 41 or diagonally above the wiring hole 41.

[0094] like Figure 6 As shown, when the orthographic projection of the fixing surface 511 of the first fixing bracket 51 on the partition 40 is directly above the wiring hole 41, the wiring lead-out side of the bus switch 3014 is closer to the wiring hole 41, thereby further shortening the length of the connecting wiring 303 in the electrical compartment 30b.

[0095] Additionally, when the orthographic projection of the fixing surface 511 of the first fixing bracket 51 onto the partition 40 is directly above the wiring hole 41, as... Figure 6 As shown, the first fixing frame 51 and the bottom of the battery compartment 30a form an accommodating space 512, and a busbar 3019 is fixed in the accommodating space 512.

[0096] Thus, since the wiring hole 41 is located on the side of the fixing surface 511 of the first fixing frame 51 near the bottom of the electrical compartment 30b, the accommodating space 512 formed by the first fixing frame 51 and the bottom of the electrical compartment 30b is easily aligned with the wiring hole 41 on the partition 40. Consequently, the busbar 3019 provided in the accommodating space 512 is easily aligned with the connecting wire 303 extending in a straight line to the wiring hole 41. This shortens the length of the connecting wire 303 in the electrical compartment 30b and reduces or even avoids bending of the connecting wire 303 in the electrical compartment 30b.

[0097] In some implementations, such as Figure 7 As shown in Figure 8, a first support member 60 is also provided inside the electrical compartment 30b. The first support member 60 is located on the side of the fixed bracket 50 near the top of the battery compartment 30a, and the first support member 60 is used to support the power distribution cabinet 3013.

[0098] In this way, a first fixing area 3011 can be formed in the area of ​​the first support member 60 near the top of the electrical compartment 30b, so that the power distribution cabinet 3013 can be fixed in the first fixing area 3011, while the first support member 60 supports the power distribution cabinet 3013, ensuring the stability of the power distribution cabinet 3013 fixed in the electrical compartment 30b.

[0099] The first support member 60 can be directly fixed to the back plate of the electrical compartment 30b, or it can be fixed to the fixed bracket 50 (such as the second fixed bracket 52), or it can be fixedly connected to both the back plate of the electrical compartment 30b and the fixed bracket 50 at the same time, so as to ensure the stability of the first support member 60 in the electrical compartment 30b, thereby ensuring the reliability of the support for the distribution cabinet 3013.

[0100] Furthermore, the first support member 60 can be a right-angled triangular gusset, which facilitates the fixation of the first support member 60 within the electrical compartment 30b and saves space occupied by the first support member 60 within the electrical compartment 30b. Of course, the first support member 60 can be other shapes of support structures, etc., and the embodiments of this application are not limited in this regard.

[0101] In some implementations, such as Figure 6 or Figure 8 As shown, the electrical compartment 30b has a first compartment wall 301 and a second compartment wall 302 arranged opposite to each other along the width direction Y of the electrical compartment 30b; the fixed bracket 50 is arranged adjacent to the first compartment wall 301, and there is a second fixing area 3012 between the fixed bracket 50 and the second compartment wall 302, the second fixing area 3012 is used to fix the fire tank 3016.

[0102] Thus, based on the arrangement of the fixed parts adjacent to the first compartment wall 301, the space inside the electrical compartment 30b is rationally utilized, thereby saving the second fixing area 3012 used for fixing the fire tank 3016. At the same time, combined with the separate fixing of the fire tank 3016 in the electrical compartment 30b, the fixing of the components in the electrical compartment 30b is further simplified, and the maintenance of the independently fixed components is facilitated, thereby improving maintenance efficiency.

[0103] Specifically, the second fixed area 3012 between the fixed bracket 50 and the second compartment wall 302 can be the area on the second compartment wall 302 that is directly opposite to the fixed bracket 50. In this case, the fixed assembly of the fire tank 3016 in the second fixed area 3012 means that the fire tank 3016 is fixed on the second compartment wall 302, and the fixed fire tank 3016 is set directly opposite to the fixed bracket 50 in the width direction Y of the electrical compartment 30b.

[0104] In some implementations, such as Figure 6 As shown, a second support member 70 is also provided inside the electrical compartment 30b. The second support member 70 is located between the fixed bracket 50 and the second compartment wall 302. The second support member 70 is used to support the fire tank 3016.

[0105] In this way, a second fixing area 3012 can be formed in the area of ​​the second support member 70 near the top of the electrical compartment 30b, so that the fire tank 3016 can be fixed in the second fixing area 3012, while the fire tank 3016 is supported by the second support member 70, ensuring the stability of the fire tank 3016 fixed in the electrical compartment 30b.

[0106] The second support member 70 can be directly fixed to the bottom of the electrical compartment 30b (e.g., on the base plate), or to the second compartment wall 302, or simultaneously fixed to both the bottom of the electrical compartment 30b and the second compartment wall 302, to ensure the stability of the second support member 70 within the electrical compartment 30b, thereby ensuring the reliability of the support for the fire tank 3016. Furthermore, the second support member 70 can form a clearance space with the bottom of the electrical compartment 30b, facilitating the wiring arrangement at the bottom of the electrical compartment 30b.

[0107] In addition, the structure of the second support member 70 can refer to the structure of the first support member 60 described above. Of course, the structure of the second support member 70 can also be different from the structure of the first support member 60. This application does not limit this aspect.

[0108] In some embodiments, the first fixing frame 51 described above is supported and fixed to the bottom of the electrical compartment 30b, such as... Figure 6 As shown, the second fixing frame 52 is supported on the second support member 70 and is fixedly connected to the side wall of the first fixing frame 51.

[0109] Thus, based on the fixed connection between the second fixing frame 52 and the first fixing frame 51, and the support of the second fixing frame 52 on the second support member 70, the stability of the second fixing frame 52 is ensured, thereby ensuring the reliability of the second fixing frame 52 in supporting the power supply host 3015. In addition, based on the fixed connection between the second fixing frame 52 and the side wall of the first fixing frame 51, the second fixing frame 52 is prevented from interfering with the fixing area of ​​the first fixing frame 51, that is, ensuring that the first fixing frame 51 has a sufficient fixing area, thereby ensuring the reliability of fixing the bus switch 3014, or the bus switch 3014 and the fuse 3017.

[0110] In this case, in conjunction with the structure of the second fixed frame 52 described above, the support frame or guide rail bracket 523 of the second fixed frame 52 can be supported on the second support member 70, and the support frame or guide rail bracket 523 of the second fixed frame 52 can be fitted and fixedly connected with the support frame or guide rail bracket 523 of the first fixed frame 51, thereby ensuring the fixing surface area 511 of the second fixed frame 52 and the first fixed frame 51, and further ensuring the reliability of the fixing of the second fixed frame 52 and the first fixed frame 51.

[0111] This application also provides a power supply system 500, such as... Figure 9 As 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.

[0112] The electrical equipment 510 is electrically connected to the energy storage device 100. Thus, in conjunction with the above description, the power supply system 500 of this application, during use, leverages the high assembly and maintenance efficiency of the energy storage device 100 to ensure the reliability of the power supply from the energy storage device 100 to the electrical equipment 510.
