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, 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 combiner modules and uninterruptible power supplies (UPS). In related technologies, these components are usually directly fixed to the inner wall of the electrical compartment. This, given the limited space within the electrical compartment, not only increases the difficulty of assembling the components but also reduces assembly efficiency. 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 electrical components.

[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, 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 guide rail bracket and a fixed tray, the fixed tray being detachably fixed to the guide rail bracket and used to carry an uninterruptible power supply.

[0005] In this embodiment, by setting up the guide rail bracket inside the electrical compartment, the uninterruptible power supply (UPS) can be pre-fixed on the fixed tray outside the electrical compartment. Then, based on the fixed assembly of the fixed tray on the guide rail bracket, the UPS can be fixedly assembled inside the electrical compartment, thereby effectively reducing the assembly difficulty of the UPS and improving assembly and maintenance efficiency. In addition, the support of the fixed tray for the UPS makes it easier to ensure the stability of the UPS fixed inside the electrical compartment.

[0006] According to one embodiment of this application, the uninterruptible power supply includes a battery module and a control host; the fixed tray has a first bearing area and a second bearing area, the first bearing area and the second bearing area are distributed along the width direction of the electrical compartment, and the first bearing area is used to bear the battery module and the second bearing area is used to bear the control host.

[0007] In this embodiment, the first and second bearing areas partitioned on the fixed tray facilitate the integrated assembly of the battery module and the control host. This also shortens the electrical connection lines between the battery module and the control host, reducing redundant wiring and minimizing interference between the electrical connection lines and other low-voltage and high-voltage wiring harnesses within the electrical compartment, thus improving the safety of the electrical connection. Furthermore, it reduces the space occupied by the electrical connection lines, thereby increasing the space utilization rate within the electrical compartment.

[0008] According to one embodiment of this application, a spacer is provided on the fixed tray, and the spacer is located between the first bearing area and the second bearing area.

[0009] In this embodiment, the first bearing area and the second bearing area can be separated by an isolation component, thereby separating the battery module and the control host, so as to form a heat dissipation channel between the battery module and the control host and improve the heat dissipation effect of the battery module and the control host.

[0010] According to one embodiment of this application, the fixed tray includes a bottom support plate, and a front side plate and a rear side plate fixedly connected to the bottom support plate and disposed opposite to each other along the depth direction of the electrical compartment; the isolation member has a strip-shaped structure, and the two ends of the isolation member are fixedly connected to the front side plate and the rear side plate respectively.

[0011] In this embodiment, the battery module and control host can be limited in the depth direction of the electrical compartment based on the front and rear side plates. At the same time, the first and second load-bearing areas are effectively isolated by the isolation component. Furthermore, the reliability of the front and rear side plates in limiting the battery module and control host can be ensured by tightening the front and rear side plates.

[0012] According to one embodiment of this application, a wiring hole is provided on the rear side plate, and a heat dissipation hole is provided on the front side plate, with both the wiring hole and the heat dissipation hole facing the second bearing area.

[0013] In this embodiment, the electrical connection wires on the control host can be extended out of the fixed tray based on the wiring hole, which simplifies the wiring design of the electrical connection wires. At the same time, the wiring hole and the heat dissipation hole can be set up to form a convection channel to improve the air convection rate, thereby improving the air convection efficiency and the heat dissipation effect of the control host.

[0014] According to one embodiment of this application, the rear side plate is a flat plate, the front side plate is a bent structure, and includes a first flat plate portion and a second flat plate portion, as well as a connecting plate connecting the first flat plate portion and the second flat plate portion along the depth direction of the electrical compartment; the first flat plate portion and the second flat plate portion are both disposed opposite to the rear side plate, and the distance between the first flat plate portion and the rear side plate is less than the distance between the second flat plate portion and the rear side plate.

[0015] In this embodiment, the bending structure of the front side plate allows for different dimensional designs of the first and second load-bearing areas in the electrical compartment depth direction, thereby enabling the assembly of battery modules and control hosts of different sizes within the fixed tray. This also avoids the fixed tray from excessively occupying space within the electrical compartment, ensuring efficient utilization of the space within the electrical compartment.

[0016] According to one embodiment of this application, the second flat plate is provided with the heat dissipation holes, and the two ends of the isolation member are fixedly connected to the second flat plate and the rear side plate, respectively.

[0017] In this embodiment, the position of the isolator can be adjusted to ensure that the control host and the first or second plate facing it extend beyond the width of the electrical compartment, thereby avoiding continuous and complete obstruction of the heat dissipation holes and wiring, and ensuring the reliability of air convection between the heat dissipation holes and wiring holes.

[0018] According to one embodiment of this application, the fixed tray further includes a first side plate and a second side plate fixedly connected to the bottom support plate and disposed opposite to each other along the width direction of the electrical compartment. The first side plate has an edge away from the bottom support plate in the height direction of the electrical compartment, and the second side plate has an outwardly turned edge at the edge away from the bottom support plate in the height direction of the electrical compartment. The fixed tray further includes a fixing member, which is fixedly connected to the two outwardly turned edges and is used to limit the battery module and the control host along the height direction of the electrical compartment.

[0019] In this embodiment, the battery module and control host can be limited in the width direction of the electrical compartment based on the setting of the first side plate and the second side plate, thereby ensuring the stability of the battery module and control host on the fixed tray; in addition, the battery module and control host can be limited in the height direction of the electrical compartment based on the setting of the fastener, thereby ensuring the stability of the battery module and control host on the fixed tray.

[0020] According to one embodiment of this application, the fixed tray includes a plurality of fixing members, which are spaced apart along the depth direction of the electrical compartment.

[0021] According to one embodiment of this application, the fastener is a bent metal structure, and a buffer layer is provided on at least the surface of the fastener facing the base plate.

[0022] According to one embodiment of this application, the fixed tray further includes a protective plate, which is fixed to the fixing member and arranged parallel to the bottom support plate.

[0023] In this embodiment, the protective plate is fixed to the fastener, which facilitates the covering of the battery module and the control host. This prevents other electrical components from falling and impacting the battery module and the control host when they are fixed in the electrical compartment. At the same time, it can prevent workers from accidentally touching the battery module and the control host, thus improving the safety of electricity use.

[0024] According to one embodiment of this application, a limiting block is provided on the bottom support plate. The limiting block is located on the side close to the rear side plate and is used to cooperate with the front side plate to limit the control host along the depth direction of the electrical compartment.

[0025] In this embodiment, the setting of the limiting block can limit the control host along the depth direction of the electrical compartment. At the same time, a wiring space can be formed between the limiting block and the rear side plate, which can simplify wiring and avoid excessive bending of the wiring, thus shortening its service life.

[0026] According to one embodiment of this application, the electrical compartment has a compartment opening and a back plate facing the compartment opening; the guide rail bracket includes a pair of fixed guide rails arranged in parallel, the fixed guide rails being arranged along the depth direction of the electrical compartment, and having a limiting end near the back plate and a fixed end away from the back plate; the limiting end has an abutment plate bent toward the fixed tray, the fixed end has a fixed flap bent away from the fixed tray, the fixed tray abuts against the abutment plate and is detachably fixedly connected to the fixed flap.

[0027] In this embodiment, the fixed pallet can be effectively limited in the depth direction of the electrical compartment by the abutment plate and the fixed connection between the fixed pallet and the fixed flip plate, and the fixed pallet can be reliably fixed on a pair of fixed guide rails, thereby ensuring the stability of the power module assembly in the electrical compartment.

[0028] According to one embodiment of this application, the abutment plate has a limiting hole, and the fixed tray is provided with a limiting arm, which is detachably inserted into the limiting hole.

[0029] In this embodiment, the limiting arm can be inserted into the limiting hole on the abutment plate, thereby limiting the limiting arm in the height and width directions of the electrical compartment, and thus limiting the fixed pallet in the height and width directions of the electrical compartment, thereby ensuring the stability of the fixed pallet on the fixed guide rail.

[0030] According to one embodiment of this application, the limiting end has a first limiting plate bent toward the fixed tray, the first limiting plate is located on the side of the abutment plate away from the fixed end of the fixed guide rail, and the first limiting plate abuts against the end of the limiting arm.

[0031] In this embodiment, the limiting arm can be limited in the depth direction of the electrical compartment based on the setting of the first limiting plate, thereby further ensuring the stability of the fixed tray on the fixed guide rail; in addition, when the first limiting plate and the limiting arm abut, a wiring gap can be formed between the fixed tray and the back plate of the electrical compartment based on the length of the limiting arm, thereby facilitating the arrangement of the wiring of the control host on the fixed tray and reducing the wiring difficulty.

[0032] According to one embodiment of this application, the edge of the opening of the limiting hole abuts against the surface of the limiting arm along the depth direction of the electrical compartment; the limiting end has a second limiting plate bent toward the fixed tray, the second limiting plate has a gap with the end of the limiting arm, and abuts against the back plate.

[0033] In this embodiment, the limiting arm can be limited along the width, depth, and height directions of the electrical compartment based on the limiting hole, ensuring the reliability of the fixed pallet's limiting. At the same time, a wiring gap can be formed between the fixed pallet and the back plate of the electrical compartment based on the gap between the second limiting plate and the end of the limiting arm, thereby facilitating the arrangement of the wiring of the control host on the fixed pallet and reducing the difficulty of wiring.

[0034] According to one aspect of this application, an energy storage device is provided, comprising: the energy storage container described in the above aspect; and a plurality of energy storage units assembled inside the energy storage container.

Detailed Implementation

[0052] 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.

[0053] 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.

[0054] 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.

[0055] Taking electrochemical energy storage as an example, this solution provides an energy storage device for use in an energy storage system. The energy storage device 100 is equipped with a set of chemical batteries, which mainly use the chemical elements in the chemical batteries as the energy storage medium. The charging and discharging process is accompanied by the chemical reaction or change of the energy storage medium. 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 electrical energy is released for use, or transferred to places with a shortage of electricity for use.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] Among them, such as Figure 3 As shown, the energy storage container 10 includes an outer frame 31, and an installation position 35 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 35.

[0067] 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 below). Each inner frame 32 has support positions 36 distributed at intervals along the height direction of the energy storage container 10 (i.e., the height direction H of the electrical compartment below). In this way, the mounting position 35 of the energy storage unit 20 can be formed based on the support positions 36 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.

[0068] 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 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 below). Each connecting horizontal beam 322 is fixedly connected to the multiple connecting vertical beams 321.

[0069] 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 36 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 36, the plurality of inner frames 32 include the outermost inner frame 32 located in the width direction (i.e., the depth direction S of the electrical compartment below) of the energy storage container 10, and all the connecting beams 322 included in the outermost inner frame 32 are fixed on one side of the connecting vertical beam 321 near 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 321 along the width direction (i.e., the depth direction S of the electrical compartment below).

[0070] 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.

[0071] 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.

[0072] 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 (i.e., the depth direction S of the electrical compartment below) of the energy storage container 10 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 (i.e., the height direction H of the electrical compartment below) and a force along the depth direction (i.e., the width direction Y of the electrical compartment 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.

[0073] 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.

[0074] 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 rear 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 below), and a side end panel located between the cabinet door and the rear panel. Furthermore, the mounting positions 35 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 35 after the cabinet door is opened.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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 below). In combination 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.

[0079] 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.

[0080] In some implementations, the distance from the support beam to the front bottom beam is less than the distance to the rear bottom beam.

[0081] Thus, with the bottom frame 311 and top frame 312 having a rear plate 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.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] The housing 30 is the structure composed of the outer frame 31, inner frame 32, bottom plate, top plate, cabinet door and side plate mentioned above; the partition 40 is fixed between the bottom plate and the top plate to divide the area enclosed by the outer frame 31 into battery compartment 30a and electrical compartment 30b.

[0087] The battery compartment 30a and the electrical compartment 30b can be distributed along the width direction (i.e., the depth direction S of the electrical compartment below) or along the depth direction (i.e., the width direction Y of the electrical compartment below) of the energy storage container 10, 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 circuit breakers, fuses, uninterruptible power supplies 50, etc.). A high-voltage junction box can also be installed in either the battery compartment 30a or the electrical compartment 30b to achieve electrical connection between the circuit breaker and the energy storage unit 20, thereby providing high-voltage protection for the energy storage unit 20.

[0088] Additionally, a partition 40 can be installed inside the housing 30 to separate the battery compartment 30a and the electrical compartment 30b; of course, if Figure 3 and Figure 5 As shown, multiple partitions 40 can also be provided inside the container 30 to divide the inner cavity 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) of the energy storage container 10.

[0089] The cooling chamber 30c is equipped with a liquid cooling system, which includes a cooling unit, a liquid storage tank, and liquid cooling pipelines (not shown in the figure) 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.

[0090] The liquid cooling pipeline includes primary pipeline, secondary pipeline and tertiary pipeline. The primary pipeline connects to the liquid storage tank in the cooling chamber 30c and extends to the battery compartment 30a. Multiple secondary pipelines connect to the primary pipeline and extend to the position between each two adjacent inner frames 32. Multiple tertiary pipelines connect to the secondary pipeline and connect to the cooling plate of each energy storage unit 20.

[0091] In related technologies, the electrical components assembled inside the electrical compartment 30b are usually wall-mounted with the uninterruptible power supply 50, meaning the uninterruptible power supply 50 is directly fixed to the inner wall of the electrical compartment 30b. The confined space within the electrical compartment 30b not only increases the initial assembly difficulty and reduces the efficiency of the uninterruptible power supply (UPS) 50, but also increases the difficulty and reduces the efficiency of subsequent maintenance. The UPS 50 is rigidly fixed to the inner wall of the electrical compartment 30b without any buffer structure, making it highly susceptible to vibration during operation. This can lead to broken or loose wiring, or even UPS malfunction. Furthermore, the fixed UPS 50 to the inner wall of the electrical compartment 30b increases the load-bearing capacity of the inner wall, making it prone to deformation and tearing. This can result in displacement of the UPS 50, causing broken or loose wiring, or even UPS malfunction. Finally, the fixed UPS 50 to the inner wall of the electrical compartment 30b restricts its heat dissipation area, thus reducing its cooling effect.

[0092] In the embodiments of this disclosure, such as Figure 5 As shown, the electrical compartment 30b is equipped with a guide rail bracket 33 and a fixed tray 34. The fixed tray 34 is detachably fixed on the guide rail bracket 33 and is used to carry the uninterruptible power supply 50 (not shown in the figure).

[0093] Thus, by setting the guide rail bracket 33 inside the electrical compartment 30b, the uninterruptible power supply 50 can be pre-fixed on the fixed tray 34 outside the electrical compartment 30b. Then, based on the fixed assembly of the fixed tray 34 on the guide rail bracket 33, the uninterruptible power supply 50 can be fixedly assembled inside the electrical compartment 30b, thereby effectively reducing the assembly difficulty of the uninterruptible power supply 50 and improving assembly and maintenance efficiency. Furthermore, the fixation of the uninterruptible power supply 50 inside the fixed tray 34, based on the guide rail bracket 33, achieves vibration buffering, thereby effectively preventing vibration from affecting the uninterruptible power supply. The synchronous vibration of the 50 avoids faults such as broken or loose connecting wires. In addition, the uninterruptible power supply 50 is fixed in the fixed tray 34. The support of the fixed tray 34 for the uninterruptible power supply 50 ensures the stability of the uninterruptible power supply 50 in the electrical compartment 30b, thereby avoiding faults such as broken or loose connecting wires caused by displacement of the uninterruptible power supply 50. Furthermore, the fixation of the uninterruptible power supply 50 in the fixed tray 34 effectively ensures the heat dissipation area of ​​the uninterruptible power supply 50, thereby ensuring the heat dissipation effect of the uninterruptible power supply 50.

[0094] Among them, such as Figure 5As shown, the electrical compartment 30b has a compartment opening 301, a back plate 302 facing the compartment opening 301, and compartment walls 303 disposed opposite each other along the width direction Y of the electrical compartment 30b. At this time, the guide rail bracket 33 can be fixed to the back plate 302 or the compartment wall 303 inside the electrical compartment 30b, and the guide rail bracket 33 can guide and assemble the fixed tray 34 in the depth direction S (i.e., the direction perpendicular to the back plate 302) of the electrical compartment 30b.

[0095] In some implementations, such as Figure 6 As shown, the guide rail bracket 33 includes a pair of parallel fixed guide rails 331, and the fixed tray 34 is detachably fixed on the pair of fixed guide rails 331.

[0096] Among them, a pair of fixed guide rails 331 can be fixed in the electrical compartment 30b by means of triangular brackets, support frames, etc., to ensure reliable support for the fixed pallet 34 and guide the fixed pallet 34.

[0097] The length direction of the fixed guide rail 331 can be parallel to the depth direction S of the electrical compartment 30b, that is, the fixed guide rail 331 is set along the depth direction S of the electrical compartment 30b. The cross-section of the fixed guide rail 331 (i.e., the cross-section perpendicular to the length direction) can be an L-shaped structure, so that mutually perpendicular support surfaces and guide surfaces are formed on the fixed guide rail 331. Thus, based on the two support surfaces on the pair of fixed guide rails 331, the fixed pallet 34 is supported in the height direction H of the electrical compartment 30b, and based on the two opposing guide surfaces on the pair of fixed guide rails 331, the fixed pallet 34 is guided in the depth direction S of the electrical compartment 30b, while limiting the fixed pallet 34 in the width direction Y of the electrical compartment 30b.

[0098] In some embodiments, the backplate 302 of the electrical compartment 30b is incorporated, such as Figure 6 and Figure 7 As shown, the fixed guide rail 331 has a limiting end (not shown in the figure) near the back plate 302 and a fixed end (not shown in the figure) away from the back plate 302; the limiting end has an abutment plate 332 bent toward the fixed tray 34, and the fixed end has a fixed flap 333 bent toward the fixed tray 34. The fixed tray 34 abuts against the abutment plate 332 and is detachably fixedly connected to the fixed flap 333.

[0099] In this way, the fixed pallet 34 can be effectively limited in the depth direction S of the electrical compartment 30b by the limiting of the fixed pallet 34 by the abutment plate 332 and the fixed connection between the fixed pallet 34 and the fixed flip plate 333, and the fixed pallet 34 can be reliably fixed on a pair of fixed guide rails 331, thereby ensuring the stability of the power module assembly in the electrical compartment 30b.

[0100] In this configuration, the fixed guide rail 331, which incorporates the L-shaped structure described above, includes a support plate and a guide plate that are perpendicular to each other. The support plate has a support surface, and the guide plate has a guide surface. The abutment plate 332 can be a structure formed by bending the end of the support plate near the back plate 302 toward the top of the electrical compartment, or a structure that is fixed separately to the support surface of the support plate and near the back plate 302. Alternatively, it can be a structure formed by bending the end of the guide plate near the back plate 302 toward the opposite fixed guide rail 331, or a structure that is fixed separately to the guide surface of the guide plate and near the back plate 302. The fixed flap 333 can be a structure formed by bending the end of the support plate away from the back plate 302 toward the bottom of the electrical compartment, or a structure that is fixed separately to the side of the support plate away from the support surface and away from the back plate 302. Alternatively, it can be a structure formed by bending the end of the guide plate away from the back plate 302 toward the opposite fixed guide rail 331, or a structure that is fixed separately to the side of the guide plate away from the guide surface and away from the back plate 302.

[0101] As for the fixed connection between the fixed tray 34 and the fixed flap 333, the fixed tray 34 may have an outer flap, and the outer flap and the fixed flap 333 may have coaxial fixing holes, so that a detachable fixed connection can be achieved by fixing bolts or the like.

[0102] In some implementations, such as Figure 7 As shown, the abutment plate 332 has a limiting hole 334, and the fixed tray 34 is provided with a limiting arm 349, which is detachably inserted into the limiting hole 334.

[0103] Thus, based on the engagement of the limiting arm 349 within the limiting hole 334, the abutment plate 332 can limit the limiting arm 349 in the height direction H and width direction Y of the electrical compartment 30b, thereby limiting the fixed pallet 34 in the height direction H and width direction Y of the electrical compartment 30b, thus ensuring the stability of the fixed pallet 34 on the fixed guide rail 331.

[0104] The limiting hole 334 on the abutment plate 332 can be a triangular through hole, a rectangular through hole, a circular through hole, etc. Correspondingly, the end face of the limiting arm 349 provided on the fixed tray 34 can also be triangular, rectangular, circular, etc. Of course, in addition to being inserted and limited based on the limiting hole 334 on the abutment plate 332, the limiting arm 349 can also have a limiting groove on the abutment plate 332, with the end of the limiting arm 349 extending into the limiting groove to achieve limiting of the limiting arm 349 in the height direction H and the width direction Y of the electrical compartment 30b.

[0105] In some implementations, such as Figure 7As shown, the limiting end of the fixed guide rail 331 has a first limiting plate 335 bent toward the fixed tray 34. The first limiting plate 335 is located on the side of the abutment plate 332 away from the fixed end of the fixed guide rail 331, and the first limiting plate 335 abuts against the end of the limiting arm 349.

[0106] Thus, based on the setting of the first limiting plate 335, the limiting arm 349 can be limited in the depth direction of the electrical compartment 30b, thereby further ensuring the stability of the fixed tray 34 on the fixed guide rail 331; in addition, when the first limiting plate 335 and the limiting arm 349 abut, a wiring gap can be formed between the fixed tray 34 and the back plate 302 of the electrical compartment 30b based on the length of the limiting arm 349, thereby facilitating the arrangement of wiring of the control host 70 on the fixed tray 34 and reducing the difficulty of wiring.

[0107] In conjunction with the L-shaped fixed guide rail 331 described above, the first limiting plate 335 can be formed in a manner similar to the abutting plate 332 described above. The first limiting plate 335 and the abutting plate 332 can both be formed on the support plate, or both on the guide plate, or one can be formed on the support plate and the other on the guide plate. This application does not limit the specific implementation of these embodiments.

[0108] In other implementations, such as Figure 8 and Figure 9 As shown, the edge of the opening of the limiting hole 334 abuts against the surface of the limiting arm 349 along the depth direction S of the electrical compartment 30b; the limiting end of the fixed guide rail 331 has a second limiting plate 336 bent toward the fixed tray 34, there is a gap between the second limiting plate 336 and the end of the limiting arm 349, and it abuts against the back plate 302.

[0109] In this way, the limiting arm 349 can be limited along the width direction Y, depth direction S, and height direction H of the electrical compartment 30b based on the limiting hole 334, ensuring the reliability of the limiting of the fixed tray 34. At the same time, based on the gap between the second limiting plate 336 and the end of the limiting arm 349, a wiring gap can be formed between the fixed tray 34 and the back plate 302 to facilitate the arrangement of wiring from the control host 70 on the fixed tray 34, thereby reducing the difficulty of wiring.

[0110] In conjunction with the L-shaped fixed guide rail 331 described above, the second limiting plate 336 can be formed in the same way as the abutting plate 332 described above. The second limiting plate 336 and the abutting plate 332 can both be formed on the support plate, or both on the guide plate, or one can be formed on the support plate and the other on the guide plate. This application does not limit this aspect.

[0111] In this embodiment of the application, the uninterruptible power supply 50 is an electrical device that needs to be installed in the electrical compartment 30b, and the uninterruptible power supply 50 includes at least a control host 70.

[0112] For example, such as Figure 8 and Figure 10 As shown, the uninterruptible power supply 50 includes a battery module 60 and a control host 70. The fixed tray 34 has a first bearing area 34a and a second bearing area 34b. The first bearing area 34a carries the battery module 60, and the second bearing area 34b carries the control host 70. Thus, the partitioned first bearing area 34a and second bearing area 34b on the fixed tray 34 facilitates the integrated assembly of the battery module 60 and the control host 70. It also shortens the electrical connection lines between the battery module 60 and the control host 70, reducing redundant wiring and minimizing interference between the electrical connection lines and other low-voltage and high-voltage wiring harnesses within the electrical compartment 30b, thereby improving the safety of the electrical connection. Furthermore, it reduces the space occupied by the electrical connection lines, thus improving the space utilization rate within the electrical compartment 30b.

[0113] The first bearing area 34a and the second bearing area 34b can be distributed along the width direction Y of the electrical compartment 30b, or along the depth direction S of the electrical compartment 30b, etc.

[0114] In some implementations, such as Figure 8 or Figure 10 As shown, a spacer 346 is provided on the fixed tray 34, and the spacer 346 is located between the first bearing area 34a and the second bearing area 34b.

[0115] In this way, the first bearing area 34a and the second bearing area 34b can be separated based on the isolation component 346, thereby separating the battery module 60 and the control host 70, so as to form a heat dissipation channel between the battery module 60 and the control host 70 and improve the heat dissipation effect of the battery module 60 and the control host 70.

[0116] The fixed tray 34 includes at least a base plate 341 to ensure support for the battery module 60 and the control host 70. In this case, the separator 346 can be a block structure fixed to the base plate 341, with multiple separators 346 spaced apart on the base tray, and the arrangement direction of the spaced-apart structure is perpendicular to the distribution direction of the first and second support areas 34b. Alternatively, the separator 346 can be a strip structure, with its length direction perpendicular to the distribution direction of the first and second support areas 34b, to simplify the assembly of the separators 346 on the base plate 341 and improve the assembly efficiency of the fixed tray 34.

[0117] Of course, such as Figure 8As shown, the fixed pallet 34 includes a bottom support plate 341, a front side plate 342, and a rear side plate 343. The front side plate 342 and the rear side plate 343 are both fixedly connected to the bottom support plate 341 and are arranged opposite to each other along the depth direction S of the electrical compartment 30b.

[0118] Thus, by combining the front side panel 342 and the rear side panel 343, the battery module 60 and the control host 70 can be limited in the depth direction S of the electrical compartment 30b.

[0119] Among them, such as Figure 8 As shown, the separator 346 can be a strip-shaped structure, and its two ends are fixedly connected to the front side plate 342 and the rear side plate 343, respectively. Thus, in addition to effectively isolating the first bearing area 34a and the second bearing area 34b through the separator 346, the separator 346 can also tighten the front side plate 342 and the rear side plate 343, ensuring the reliability of the front side plate 342 and the rear side plate 343 in limiting the battery module 60 and the control host 70.

[0120] In addition, such as Figure 10 As shown, a wire buckle 3432 is provided on the surface of the rear side panel 343 that is opposite to the front side panel 342. Based on the setting of the wire buckle 3432, it is convenient to fix the wiring, thereby improving the neatness of the wiring and avoiding crosstalk with other wiring.

[0121] In some implementations, such as Figure 10 and Figure 11 As shown, a limit block 3411 is provided on the bottom support plate 341. The limit block 3411 is located on the side near the rear side plate 343 and is used to cooperate with the front side plate 342 to limit the control host 70 along the depth direction S of the electrical compartment 30b.

[0122] Thus, based on the setting of the limit block 3411, the control host 70 can be limited along the depth direction S of the electrical compartment 30b. At the same time, a wiring space can be formed between the limit block 3411 and the rear side plate 343, which facilitates simplified wiring and avoids excessive bending of the wiring, thus shortening its service life.

[0123] In some implementations, such as Figure 8 or Figure 10 As shown, a wiring hole 3431 is provided on the rear side plate 343, and the wiring hole 3431 is directly opposite the second bearing area 34b.

[0124] In this way, the electrical connection wires on the control host 70 can be extended out of the fixed tray 34 based on the wiring hole 3431, simplifying the wiring design of the electrical connection wires. At the same time, the wiring hole 3431 can be used to form a heat dissipation through hole, improving the heat dissipation effect of the control host 70 on the rear panel 343 side.

[0125] The control host 70 has a cooling fan at the rear end facing the rear panel 343. In this case, the wiring hole 3431 on the rear panel 343 has an area facing the wiring port on the control host 70 and an area facing the cooling fan, thus simplifying the wiring design while ensuring the heat dissipation effect of the control host 70.

[0126] In some implementations, such as Figure 8 As shown, a heat dissipation hole 3421 is provided on the front side plate 342, and the heat dissipation hole 3421 is directly opposite the second bearing area 34b.

[0127] Thus, based on the setting of the heat dissipation hole 3421, the control host 70 can achieve effective heat dissipation on the front side panel 342 side; in addition, combined with the above-mentioned wiring hole 3431, the wiring hole 3431 and the heat dissipation hole 3421 can be set to face each other, thereby forming a convection channel to improve the air convection rate, thereby improving the air convection efficiency and improving the heat dissipation effect of the control host 70.

[0128] In the case where the wiring hole 3431 and the heat dissipation hole 3421 are directly opposite each other, after the control host 70 is assembled, in order to avoid the control host 70 obstructing the wiring hole 3431 and the heat dissipation hole 3421 and affecting the air convection effect between the wiring hole 3431 and the heat dissipation hole 3421, the wiring hole 3431 and the heat dissipation hole 3421 can be set to extend out of the control host 70 on the same side of the width direction Y of the electrical compartment 30b. This will ensure that the wiring hole 3431 and the heat dissipation hole 3421 have a directly opposite area on one side of the control host 70, thereby ensuring the air convection effect between the wiring hole 3431 and the heat dissipation hole 3421 on one side of the control host 70, that is, ensuring the heat dissipation effect of the control host 70. In conjunction with the aforementioned isolator 346, the orthographic projection of the isolator 346 on the rear panel 343 can be positioned directly above the wiring hole 3431, and the orthographic projection of the isolator 346 on the front panel 342 can be positioned directly above the heat dissipation hole 3421. Thus, after the separation between the battery module 60 and the control host 70 is achieved based on the isolator 346, it is ensured that there is a directly opposite area between the heat dissipation hole 3421 and the wiring hole 3431 between the battery module 60 and the control host 70.

[0129] In some implementations, such as Figure 8 As shown, the rear side panel 343 is a flat panel, and the front side panel 342 is a bent structure, including a first flat plate portion 3422 and a second flat plate portion 3423, and a connecting plate 3424 connecting the first flat plate portion 3422 and the second flat plate portion 3423 along the depth direction S of the electrical compartment 30b; the first flat plate portion 3422 and the second flat plate portion 3423 are both arranged opposite to the rear side panel 343, and the distance between the first flat plate portion 3422 and the rear side panel 343 is smaller than the distance between the second flat plate portion 3423 and the rear side panel 343.

[0130] Thus, by bending the front panel 342, different sizes of the first bearing area 34a and the second bearing area 34b in the depth direction S of the electrical compartment 30b can be achieved, thereby enabling the assembly of battery modules 60 and control host 70 of different sizes in the fixed tray 34. At the same time, compared with the equal size design of the first bearing area 34a and the second bearing area 34b in the depth direction S of the electrical compartment 30b, the fixed tray 34 avoids occupying too much space in the electrical compartment 30b, ensuring the efficient utilization of space in the electrical compartment 30b.

[0131] Specifically, a first bearing area 34a may be formed between the first flat plate portion 3422 and the rear side plate 343, and a second bearing area 34b may be formed between the second flat plate portion 3423 and the rear side plate 343; alternatively, a second bearing area 34b may be formed between the first flat plate portion 3422 and the rear side plate 343, and a first bearing area 34a may be formed between the second flat plate portion 3423 and the rear side plate 343.

[0132] Specifically, the isolation member 346 described above can be fixed between the first flat plate portion 3422 and the rear side plate 343, or it can be fixed between the second flat plate portion 3423 and the rear side plate 343. For example, as... Figure 8 As shown, the first flat plate 3422 and the rear side plate 343 form a first bearing area 34a, and the second flat plate 3423 and the rear side plate 343 form a second bearing area 34b. In this case, the second bent plate is provided with heat dissipation holes 3421, and the two ends of the isolation member 346 are fixedly connected to the second flat plate 3423 and the rear side plate 343 respectively; or, the first flat plate 3422 and the rear side plate 343 form a second bearing area 34b, and the second flat plate 3423 and the rear side plate 343 form a first bearing area 34a. In this case, the first bent plate is provided with heat dissipation holes 3421, and the two ends of the isolation member 346 are fixedly connected to the first flat plate 3422 and the rear side plate 343 respectively.

[0133] In this way, based on the position adjustment of the isolator 346, it can be ensured that the control host 70 and the first plate part 3422 or the second plate part 3423 facing each other extend from the control host 70 in the width direction Y of the electrical compartment 30b, thereby avoiding continuous complete obstruction of the heat dissipation hole 3421 and the wiring, so as to ensure the reliability of air convection between the heat dissipation hole 3421 and the wiring hole 3431.

[0134] In addition, such as Figure 8 As shown, after the isolation member 346 is fixedly connected to the rear side plate 343 and the second flat plate portion 3423 respectively, the isolation member 346 and the connecting plate 3424 can be spaced apart, abutted, or fixed by welding, etc. The embodiments of this application do not limit this.

[0135] In some implementations, such as Figure 10 and Figure 12 As shown, the fixed pallet 34 also includes a first side plate 344 and a second side plate 345 that are fixedly connected to the bottom support plate 341 and are disposed opposite to each other along the width direction Y of the electrical compartment 30b.

[0136] In this way, based on the setting of the first side plate 344 and the second side plate 345, the battery module 60 and the control host 70 can be limited in the width direction Y of the electrical compartment 30b, thereby ensuring the stability of the battery module 60 and the control host 70 fixed on the fixed tray 34.

[0137] The first side plate 344, the second side plate 345, and the bottom tray can be an integrally bent U-shaped structure or a U-shaped structure welded together. The front side plate 342 and the rear side plate 343 can be welded between the first side plate 344 and the second side plate 345, or the edges of the first side plate 344 and the second side plate 343 near the front side plate 342 and the rear side plate 343 can have opposing flange structures, and then the front side plate 342 can be fixedly connected to the first side plate 344 and the second side plate 345, and the rear front side plate 342 can be fixedly connected to the first side plate 344 and the second side plate 345 by fixing bolts. Preferably, the front side plate 342 and the rear side plate 343 can be welded between the first side plate 344 and the second side plate 345, and the edges of the first side plate 344 and the second side plate near the front side plate 342 have a flange structure, so as to fix the flange structure on the first side plate 344 and the second side plate 345 (i.e. the outer flange of the fixed tray 34 mentioned above) to the guide rail bracket 33 (such as the fixed flange 333 on the fixed guide rail 331).

[0138] Specifically, by combining the aforementioned isolator 346 with the first side plate 344 and the second side plate 345 respectively, the battery module 60 and the control host 70 can be limited in the width direction Y of the electrical compartment 30b. Furthermore, by combining the aforementioned limiting block 3411, the orthographic projection of the limiting block 3411 on the bottom support plate 341 can be an L-shaped structure. In this case, in addition to limiting the control host 70 in the depth direction S of the electrical compartment 30b by combining the limiting block 3411 with the front side plate 342, the limiting block 3411 can also limit the control host 70 in the width direction Y of the electrical compartment 30b by combining with the first side plate 344 or the second side plate 345 adjacent to the control host 70. This further ensures the reliability of the limiting of the battery module 60 and the control host 70 in the width direction Y and depth direction S of the electrical compartment 30b.

[0139] In some implementations, such as Figure 12As shown, the first side plate 344 has an edge away from the bottom support plate 341 in the height direction H of the electrical compartment 30b, and the second side plate 345 has an outward flange 3441 in the height direction H of the electrical compartment 30b. The fixed tray 34 also includes a fixing member 347, which is fixedly connected to the two outward flanges 3441 and is used to limit the battery module 60 and the control host 70 along the height direction H of the electrical compartment 30b.

[0140] In this way, based on the setting of the fastener 347, the battery module 60 and the control host 70 can be limited in the height direction H of the electrical compartment 30b, thereby ensuring the stability of the battery module 60 and the control host 70 on the fixed tray 34.

[0141] The fastener 347 can be a cable tie or a bent metal structure. When the fastener 347 is a bent metal structure, it improves the reliability of the positioning of the battery module 60 and the control host 70, and also extends the lifespan of the positioning of the battery module 60 and the control host 70. Additionally, the fastener 347 can have an overall U-shaped structure, so that the outward flanges 3441 on the first side plate 344 and the second side plate 345 are lower than the battery module 60 and the control host 70, thereby ensuring effective heat dissipation for the battery module 60 and the control host 70 while simultaneously positioning them.

[0142] In addition, when the fastener 347 is a bent metal structure, a buffer layer is provided on at least the surface of the fastener 347 facing the base plate 341. This buffer layer not only facilitates isolation (physical and insulating isolation) between the fastener 347 and the battery module 60 and the control host 70, but also avoids hard contact between the fastener 347 and the battery module 60 and the control host 70, thus improving the safety of the battery module 60 and the control host 70 in use.

[0143] It should be noted that the fixed tray 34 may include one or more fasteners 347, and when the fixed tray 34 includes multiple fasteners 347, the multiple fasteners 347 are spaced apart along the depth direction S of the electrical compartment 30b. In this way, the reliability of limiting the battery module 60 and the control host 70 along the height direction H of the electrical compartment 30b is ensured by the arrangement of multiple fasteners 347.

[0144] In some implementations, such as Figure 12 As shown, the fixed tray 34 also includes a protective plate 348, which is fixed on the fastener 347 and is arranged parallel to the bottom support plate 341.

[0145] Thus, by fixing the protective plate 348 to the fastener 347, it is easy to cover the battery module 60 and the control host 70, thereby preventing other electrical components from falling and hitting the battery module 60 and the control host 70 when they are fixed in the electrical compartment 30b. At the same time, it can prevent operators from accidentally touching the battery module 60 and the control host 70, thus improving the safety of electricity use.

[0146] The protective plate 348 can be fixed to the fastener 347 by means of adhesive bonding or other methods. The orthographic projection of the protective plate 348 on the base plate 341 can coincide with the edge of the base plate 341, or at least part of the edge of the orthographic projection of the protective plate 348 on the base plate 341 can be located within the area enclosed by the edge of the base plate 341, or at least part of the edge of the orthographic projection of the protective plate 348 on the base plate 341 can be located outside the area enclosed by the edge of the base plate 341. The embodiments of this application do not limit this, as long as the protective plate 348 can effectively shield the battery module 60 and the control host 70.

[0147] This application also provides a power supply system 500, such as...
