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 energy storage container contains multiple internal frames, with multiple mounting positions between adjacent frames. These positions secure the energy storage units, ensuring the overall capacity of the energy storage device. During charging and discharging, the energy storage units are cooled via liquid-cooled piping connected to them within the energy storage container, maintaining optimal charging and discharging temperatures and ensuring safety. However, higher-positioned energy storage units have longer suspended pipe sections, increasing the risk of sagging under their own weight and thus increasing the potential for leakage and safety hazards during charging and discharging. Summary of the Invention

[0003] A primary objective of this application is to provide an energy storage container, energy storage device, and power supply system that can improve safety.

[0004] To achieve the above-mentioned objectives, this application adopts the following technical solution:

[0005] According to one aspect of this application, an energy storage container is provided, comprising: an outer frame including a bottom frame and a top frame disposed opposite each other, a plurality of columns connecting the bottom frame and the top frame, and a cabinet door fixed to the columns; a plurality of inner frames fixed between the bottom frame and the top frame and spaced apart along the width direction of the energy storage container, each inner frame including a plurality of vertical beams and a plurality of fixed guide rails fixedly connected, the plurality of fixed guide rails spaced apart along the height direction of the energy storage container, and two opposite fixed guide rails on two adjacent inner frames forming a mounting position for accommodating an energy storage unit; and a plurality of fixed supports fixedly connected between the bottom frame and the top frame and corresponding one-to-one with the plurality of inner frames, each fixed support located on the side of the corresponding inner frame near the cabinet door and having a plurality of fixed areas spaced apart along the height direction of the energy storage container.

[0006] In this embodiment, a corresponding fixed bracket is provided for each inner frame, which facilitates the fixing of the liquid cooling pipeline (partial section of the liquid cooling pipeline) connected to the energy storage unit on the fixed bracket. This prevents leakage at the connection due to the weight of the liquid cooling pipeline, thereby improving the reliability of the liquid cooling pipeline seal and ensuring the safety of the energy storage unit's charging and discharging. In addition, the wiring harness connected to the energy storage unit can also be fixed on the fixed bracket to prevent loosening at the connection due to the weight of the wiring harness, thereby improving the reliability of the wiring harness electrical connection and ensuring the safety of the energy storage unit's charging and discharging.

[0007] According to one embodiment of this application, the fixed support includes a fixed column and a plurality of fixed plates; the two ends of the fixed column are respectively fixedly connected to the bottom frame and the top frame, and the plurality of fixed plates are all fixedly connected to the fixed column and are distributed at intervals along the height direction of the energy storage container. The two ends of each fixed plate are respectively fixedly connected to the fixed column and the corresponding inner frame, and form a fixed area.

[0008] In this embodiment, the use of fixed columns and multiple fixed plates simplifies the fixing of the fixed bracket between the bottom frame and the top frame, thereby improving the assembly efficiency of the fixed bracket; at the same time, the fixed connection between the fixed plates and the inner frame ensures the stability of the fixed bracket.

[0009] According to one embodiment of this application, the end of the fixing plate near the inner frame has an outward flap, and the outward flap is fixedly connected to the vertical beams included in the inner frame.

[0010] In this embodiment, the outward flap design facilitates an increase in the fixing area between the fixing plate and the vertical beam, thereby improving the reliability of the fixing plate's fixed connection.

[0011] According to one embodiment of this application, the end face of the fixing column has a bent structure, and one end of the fixing plate abuts against the inner side of the bent angle on the fixing column.

[0012] In this embodiment, by abutting the fixing plate on the inside of the bending angle of the fixing column, it is not only easy to increase the fixing area between the fixing plate and the fixing column, but also to achieve the pre-positioning of the fixing column based on the fixing plate after the fixing plate is fixedly connected to the inner frame, thereby improving the assembly efficiency of the fixing column with the bottom frame and the top frame.

[0013] According to one embodiment of this application, the edge of the fixed column near the corresponding inner frame has a bend in the region corresponding to each fixed plate, each bend has a positioning notch, and each fixed plate is limited within the corresponding positioning notch.

[0014] In this embodiment, the fixed plate and the fixed column are positioned by means of a bend in the fixed column, which is based on the positioning notch in the bend, thereby improving the connection efficiency between the fixed plate and the fixed column. At the same time, the support of the fixed plate in the notch helps to improve the reliability of the fixed connection between the fixed plate and the fixed column, thereby ensuring the reliability of the liquid cooling pipeline and wiring harness fixing.

[0015] According to one embodiment of this application, a plurality of fixed plates correspond one-to-one with a plurality of fixed guide rails, and each fixed plate and its corresponding fixed guide rail are offset in the height direction of the energy storage container.

[0016] In this embodiment, the arrangement of multiple fixing plates facilitates the fixing of liquid cooling pipes and wiring harnesses near each fixing guide rail. At the same time, the staggered arrangement of the fixing plates and corresponding fixing guide rails facilitates the formation of a large assembly space around the fixing plates, avoiding interference from the fixing guide rails, thereby improving the fixing efficiency of liquid cooling pipes and wiring harnesses.

[0017] According to one embodiment of this application, each of the fixing plates is located on the side of the corresponding fixing guide rail close to the top frame.

[0018] In this embodiment, the fixing plate is located on the side of the corresponding fixing guide rail near the top frame, which facilitates the routing of the bent tertiary pipeline near the fixing plate, thereby ensuring the reliability of the connection between the tertiary pipeline and the secondary pipeline.

[0019] According to one embodiment of this application, the fixing plate has a plurality of fixing holes extending through the width direction of the energy storage container, and the plurality of fixing holes are spaced apart along the depth direction of the energy storage container.

[0020] In this embodiment, a first fixing position can be formed through a fixing hole, and then threaded cable ties, rivets, etc. can be wrapped around the first component to be fixed (such as a secondary pipeline or wire harness) and fixed in the fixing hole, so as to simplify the fixing method of the first component to be fixed and improve the fixing efficiency of the first component to be fixed.

[0021] According to one embodiment of this application, the fixing plate includes a body plate and a pair of upright plates connected to the body plate and disposed opposite to each other; the body plate has a through hole extending along the width direction of the energy storage container and a pair of upright plates disposed opposite to each other around the through hole; a connecting post is provided between the pair of upright plates, and the connecting post is disposed opposite to the through hole in the axial direction of the through hole.

[0022] In this embodiment, a second fixing position can be formed by a connecting post, and then a binding device such as a cable tie can be used to fix the second component to be fixed (such as a secondary pipeline or wire harness) to the connecting post. The through hole provides operable space, thereby simplifying the fixing method of the second component to be fixed and improving the fixing efficiency of the second component to be fixed.

[0023] According to one embodiment of this application, a pair of the uprights are located on both sides of the through hole along the height direction of the energy storage container.

[0024] In this embodiment, it is easy to ensure that the length direction of the connecting column is parallel to the height direction of the energy storage container, that is, to ensure that the length direction of the connecting column is parallel to the length direction of the wire harness routing, thereby avoiding friction between the wire harness routing and the binding component when bundling the wire harness routing, and extending the service life of the wire harness routing.

[0025] According to one embodiment of this application, a plurality of connecting posts are provided between a pair of upright plates; the plurality of connecting posts are spaced apart along the depth direction of the energy storage container, and at least one of the connecting posts is directly opposite the through hole in the axial direction of the through hole.

[0026] In this embodiment, the arrangement of multiple connecting columns facilitates the adjustment of the installation position of the second component to be fixed, thereby preventing the second component to be fixed from bending and ensuring reliable fixing of the second component to be fixed in multiple fixing areas.

[0027] According to one embodiment of this application, the vertical beam is fixed with the fixed guide rails on both sides in the width direction of the energy storage container; in the width direction of the energy storage container, the fixed bracket is located between the two fixed guide rails included in the corresponding inner frame.

[0028] In this embodiment, it is convenient to realize the insertion and connection of the fixed bracket between the two fixed guide rails, so as to reduce the size of the energy storage container in the depth direction while fixing the liquid cooling pipeline and wiring harness, thereby ensuring the miniaturization design of the energy storage container.

[0029] According to one aspect of this application, an energy storage device is provided, comprising: an energy storage container as described in the above aspect; a plurality of energy storage units, each of the energy storage units being fixed in an installation position formed by two adjacent inner frames; and a liquid cooling system located inside the energy storage container, including liquid cooling pipes communicating with the energy storage units, wherein a portion of the liquid cooling pipes is fixed on the fixed support.

[0030] According to one aspect of this application, a power supply system is provided, the power supply system including electrical equipment and the energy storage device described in the above aspect, the energy storage device supplying power to the electrical equipment.

[0031] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

[0056] 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.

[0057] 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.

[0058] 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.

[0059] Taking electrochemical energy storage as an example, this solution provides an energy storage device 100, which is applied to an energy storage system 1000. The energy storage device 100 is equipped with a chemical battery, which mainly uses the chemical elements in the chemical battery 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 battery. 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.

[0060] 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 100 include:

[0061] (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 source in the power supply side, the energy storage power station realizes the load matching of power in time and space, enhances the renewable energy absorption capacity, reduces instantaneous power changes, reduces the impact on the power grid, improves the problem of new energy power generation absorption, and is of great significance in power grid system backup, alleviating peak load power supply pressure and peak regulation and frequency regulation.

[0062] (2) The energy storage prefabricated cabin applied on the grid side has the main functions of peak regulation, frequency regulation and alleviating grid congestion. In terms of peak regulation, it can realize peak shaving and valley filling of electricity load, that is, charging the energy storage device 100% 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.

[0063] (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 100, 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 1000 when the electricity price is low and discharging the energy storage system 1000 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 the energy storage system 1000 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 electricity 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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. The energy storage container 10 has a plurality of mounting positions 44, which are used to accommodate the energy storage units 20, that is, each energy storage unit 20 is fixed on the corresponding mounting position 44.

[0073] Among them, such as Figure 3 and Figure 4 As shown, the energy storage container 10 is provided with multiple partitions 60, which are fixed inside the energy storage container 10 to separate the battery compartment 10a, the electrical compartment 10b, and the cooling compartment 10c. The electrical compartment 10b and the cooling compartment 10c can be located on the same side or different sides of the battery compartment 10a in the width direction of the energy storage container 10 (i.e., the length direction of the support beam 314 described below).

[0074] The battery compartment 10a contains an installation position 44 for the energy storage unit 20 and a high-voltage junction box. The electrical compartment 10b contains a UPS (Uninterruptible Power System), a circuit breaker, an energy storage converter, etc. The energy storage converter is connected between the high-voltage junction box and the circuit breaker, and the circuit breaker is used to connect to the external power grid. The high-voltage junction box and the UPS are both connected to the energy storage unit 20.

[0075] The energy storage converter is connected to the high-voltage junction box, and the high-voltage junction box is connected to the energy storage unit 20 via high-voltage wiring. The UPS is connected to the energy storage unit 20 via low-voltage wiring.

[0076] The cooling chamber 10c is equipped with a liquid cooling system, such as... Figure 3 , Figure 4 and Figure 5 As shown, the liquid cooling system includes a cooling unit 102 and a liquid storage tank 103, as well as a liquid cooling pipeline 101 connected to the energy storage unit 20. The liquid storage tank 103 is used to store fluid, and the cooling unit 102 is used to cool the fluid in the liquid storage tank 103. The cooled fluid in the liquid storage tank is circulated to the cooling plate of the energy storage unit 20 through the liquid cooling pipeline 101, so as to cool the energy storage unit based on the cooled fluid.

[0077] Among them, such as Figure 5 As shown, the liquid cooling pipeline 101 includes a primary pipeline 1011, a secondary pipeline 1012, and a tertiary pipeline 1013. The primary pipeline 1011 connects to the liquid storage tank 103 and extends into the battery compartment 10a. Multiple secondary pipelines 1012 connect to the primary pipeline 1011 and extend to the position between each pair of adjacent inner frames 40. Multiple tertiary pipelines 1013 connect to the secondary pipelines 1012 and connect to the cooling plate of each energy storage unit 20.

[0078] In some implementations, such as Figure 4 As shown, the energy storage container 10 includes an outer frame 30 and multiple inner frames 40. The multiple inner frames 40 are arranged in the area enclosed by the outer frame 30 and are distributed at intervals along the width direction Y of the energy storage container 10. Multiple mounting positions 44 are formed between two adjacent inner frames 40. The multiple mounting positions 44 are distributed in the height direction H of the energy storage container 10. Each mounting position 44 is used to fix an energy storage unit 20.

[0079] Among them, such as Figure 4 As shown, the outer frame 30 includes a bottom frame 31 and a top frame 32 disposed opposite to each other, and a plurality of columns 33 connecting the bottom frame 31 and the top frame 32. A plurality of inner frames 40 are fixed between the bottom frame 31 and the top frame 32, and a plurality of mounting positions 44 formed between two adjacent inner frames 40 are distributed along the length direction of the columns 33. As for the bottom frame 31 and the top frame 32 included in the outer frame 30, each of the above-mentioned partitions 60 is fixedly connected to the bottom frame 31 and the top frame 32 to divide the area enclosed by the outer frame 30 into a battery compartment 10a, an electrical compartment 10b, and a cooling compartment 10c.

[0080] A high-voltage junction box can be installed between each pair of adjacent inner frames 40. Since multiple energy storage units 20 can be connected in series and parallel to form a battery cluster, multiple energy storage units 20 fixed between two adjacent inner frames 40 can form one battery cluster or two battery clusters. When two battery clusters are formed, the multiple high-voltage junction boxes are all in a one-to-two mode, so that they can be connected to the multiple energy storage units 20 included in the two corresponding battery clusters through one high-voltage junction box, thereby reducing the number of high-voltage junction boxes.

[0081] In addition, the energy storage container 10 also includes a bottom plate fixed to the bottom frame 31, a top plate fixed to the top frame 32, side plates fixed between the bottom frame 31 and the top frame 32 (including a back plate opposite to the cabinet door 34 and side end plates), and as such Figure 3 and Figure 4 The cabinet door 34 is shown fixed to the column 33.

[0082] The mounting positions 44 formed by the multiple inner frames 40 can be exposed when the cabinet door 34 is opened, so that after the cabinet door 34 is opened, it is convenient for the operators to assemble the energy storage unit 20 on the mounting position 44 formed between any two adjacent inner frames 40, as well as to carry out subsequent maintenance on the energy storage unit 20 on the mounting position 44.

[0083] In some implementations, such as Figure 4 and Figure 6 As shown, the bottom frame 31 includes a front bottom crossbeam 311, a rear bottom crossbeam 312, and a pair of bottom longitudinal beams 313 that form a rectangular frame, as well as a support crossbeam 314 that is connected to the pair of bottom longitudinal beams 313 within the rectangular frame.

[0084] Thus, based on the rectangular frame formed by the front bottom crossbeam 311, the rear bottom crossbeam 312, and a pair of bottom longitudinal beams 313, the support beams 314 connected to the pair of bottom longitudinal beams 313 provide support within the rectangular frame area, thereby improving the structural strength of the bottom frame 31 and thus improving the structural strength of the outer frame 30, ensuring the load-bearing effect of the energy storage container 10 on multiple energy storage units 20.

[0085] In this design, the width direction Y of the energy storage container 10 corresponds to the length direction of the supporting beam 314. This beam, combined with the supporting beam 314 included in the bottom frame 31, supports multiple inner frames 40, ensuring the stability of the inner frames 40 within the outer frame 30. Furthermore, the front bottom beam 311 and rear bottom beam 312 of the bottom frame 31 can be distinguished based on the assembly position of the cabinet door in the energy storage container 10. Specifically, for the pair of bottom beams of the bottom frame 31 arranged parallel to the supporting beam 314, the bottom beam closer to the cabinet door is the front bottom beam 311, and the bottom beam farther from the cabinet door is the rear bottom beam 312. That is, the cabinet door is fixed to the side of the outer frame 30 closest to the front bottom beam 311.

[0086] In some embodiments, the distance from the support beam 314 to the front bottom beam 311 is less than the distance to the rear bottom beam 312.

[0087] Thus, with the bottom frame 31 and top frame 32 having backplate support on the side near the rear bottom crossbeam 312, the support crossbeam 314 is adjusted to be relatively close to the front bottom crossbeam 311, that is, the support crossbeam 314 is adjusted to be set closer to the cabinet door 34. Based on the support of the inner frame 40 between the front bottom crossbeam 311 and the top frame 32, the structural strength of the outer frame 30 on the side near the cabinet door 34 is guaranteed, thereby ensuring the load-bearing effect of the energy storage container 10 on multiple energy storage units 20.

[0088] In some implementations, such as Figure 5 or Figure 6 As shown, the bottom frame 31 also includes a plurality of supporting longitudinal beams 315 connected between the rear bottom crossbeam 312 and the front bottom crossbeam 311, and the plurality of supporting longitudinal beams 315 are all fixedly connected to the supporting crossbeam 314.

[0089] Thus, by setting up the supporting longitudinal beams 315, the structure of the bottom frame 31 is reinforced, the structural strength of the outer frame 30 is further improved, and the load-bearing effect of the energy storage container 10 on multiple energy storage units 20 is guaranteed.

[0090] Among them, multiple supporting longitudinal beams 315 correspond one-to-one with multiple inner frames 40, so that each inner frame 40 is supported and fixed on the supporting cross beam 314 and the corresponding supporting longitudinal beam 315, thereby ensuring the reliability of the bottom frame 31 in supporting multiple inner frames 40, and thus ensuring the reliability of the inner frame 40 in bearing the energy storage unit 20.

[0091] Each supporting longitudinal beam 315 can be either a one-piece structure or a separate structure. When the supporting longitudinal beam 315 is a one-piece structure, the supporting crossbeam 314 has a notch 512 facing away from the top frame 32 and corresponding to each supporting longitudinal beam 315. Each supporting longitudinal beam 315 is fixed in the corresponding notch 512 and is fixedly connected to the front bottom crossbeam 311 and the rear bottom crossbeam 312 respectively. When the supporting longitudinal beam 315 is a separate structure, such as... Figure 5 or Figure 6 As shown, the support longitudinal beam 315 includes a first longitudinal beam 3151 and a second longitudinal beam 3152 located on different sides of the support crossbeam 314. The first longitudinal beam 3151 is fixedly connected to the front bottom crossbeam 311 and the support crossbeam 314 respectively, and the second longitudinal beam 3152 is fixedly connected to the rear bottom crossbeam 312 and the support crossbeam 314 respectively.

[0092] In some implementations, such as Figure 5As shown, the inner frame 40 includes multiple vertical beams 41 and multiple fixed guide rails 42 that are fixedly connected. Specifically, the multiple vertical beams 41 are distributed at intervals along the depth direction S (i.e., the length direction of the bottom longitudinal beam 313) of the energy storage container 10, and the multiple fixed guide rails 42 are distributed at intervals along the height direction H (i.e., the length direction of the column 33) of the energy storage container 10. Each fixed guide rail 42 is fixedly connected to the multiple vertical beams 41, and two opposite fixed guide rails 42 on two adjacent inner frames 40 (i.e., two fixed guide rails 42 fixed at the same height on two adjacent inner frames) form an installation position 44.

[0093] In this way, multiple vertical beams 41 can be fixedly connected by fixed guide rails 42, which can also be used to support the energy storage unit 20, so as to realize the reuse of fixed guide rails 42. At the same time, while ensuring the reliability of supporting the energy storage unit 20, the structure of the inner frame 40 is simplified, which facilitates the lightweight design of the energy storage container 10.

[0094] In this configuration, the inner frame 40 is fixed within the outer frame 30, and the two ends of multiple vertical beams 41 are respectively fixedly connected to the bottom frame 31 and the top frame 32. Specifically, in conjunction with the supporting horizontal beam 314 and supporting vertical beam 315 included in the bottom frame 31, one of the multiple vertical beams 41 included in the inner frame 40 is supported and fixed to the supporting horizontal beam 314, and the remaining vertical beams 41 are supported and fixed to the supporting vertical beam 315, so as to ensure the stability of the inner frame 40 fixed between the bottom frame 31 and the top frame 32.

[0095] The plurality of inner frames 40 include an outermost inner frame 40 located along the length of the supporting beam 314, and all the fixed guide rails 42 included in the outermost inner frame 40 are fixed on one side of the vertical beam 41 near an adjacent inner frame 40; except for the outermost inner frame 40, all the fixed guide rails 42 included in the remaining inner frames 40 are fixed on both sides of the vertical beam 41 along the length of the supporting beam 314.

[0096] In some implementations, such as Figure 5 As shown, the inner frame 40 also includes multiple inclined beams 43, each of which is fixedly connected to multiple vertical beams 41.

[0097] Thus, the structural strength of the inner frame 40 is further improved by the reinforcement connection of the inclined beam 43 between multiple vertical beams 41. At the same time, the setting of the inclined beam 43 facilitates the structural stability of the energy storage container 10 when hoisting it.

[0098] To avoid interference with the fixed connection between the guide rail 42 and the vertical beam 41, the dimension of the inclined beam 43 in the width direction Y of the energy storage container 10 is smaller than or equal to the dimension of the vertical beam 41. Furthermore, the cross-sectional area of ​​the inclined beam 43 can be set to be greater than or equal to the cross-sectional area of ​​the vertical beam 41. This ensures that the structural strength of the inclined beam 43 is greater than that of the vertical beam 41. Consequently, during the hoisting of the energy storage container 10, since the hoisting position is located at the four corners of the energy storage container 10, the frame structure of the energy storage container 10 experiences a force that causes it to rotate towards the center. Due to the inclined orientation of the inclined beam 43, it is simultaneously subjected to forces along the height and depth directions of the energy storage container 10. Therefore, based on the structural strength of the inclined beam 43, complete deformation of the heavily stressed inclined beam 43 is avoided. The cross-sections of both the inclined beam 43 and the vertical beam 41 are perpendicular to their own length direction.

[0099] In addition, in conjunction with the above, the distance from the supporting beam 314 to the front bottom beam 311 is less than the distance to the rear bottom beam 312. In order to ensure the balance of structural strength of the outer frame 30 on both sides of the supporting beam 314, multiple inclined beams 43 can be designed asymmetrically on both sides of the supporting beam 314. That is, all the inclined beams 43 on the side of the supporting beam 314 near the front bottom beam 311 are asymmetrical with all the inclined beams 43 on the side of the supporting vertical beam 41 near the rear bottom beam 312.

[0100] In some implementations, such as Figure 5 and Figure 7 As shown, the energy storage container 10 includes multiple fixed supports 50, which are fixedly connected between the bottom frame 31 and the top frame 32 and correspond one-to-one with multiple inner frames 40. Each fixed support 50 is located on the side of the corresponding inner frame 40 near the cabinet door 34 (not shown in the figure) and has multiple fixed areas 53 distributed at intervals along the height direction H of the energy storage container 10.

[0101] Thus, a corresponding fixed bracket 50 is provided for each inner frame 40, which facilitates the fixing of the liquid cooling pipe 101 (a section of the liquid cooling pipe 101) connected to the energy storage unit 20 onto the fixed bracket 50. This prevents the liquid cooling pipe 101 from leaking at the connection due to its own weight, thereby improving the sealing reliability of the liquid cooling pipe 101 and ensuring the safety of charging and discharging the energy storage unit 20. In addition, the wiring harness connected to the energy storage unit 20 can also be fixed onto the fixed bracket 50 to prevent the wiring harness from loosening at the connection due to its own weight, thereby improving the electrical connection reliability of the wiring harness and ensuring the safety of charging and discharging the energy storage unit 20.

[0102] In conjunction with the aforementioned cabinet door, the fixing bracket 50 can be installed on the inner frame 40 near the cabinet door, facilitating the fixing of the liquid cooling pipes 101 and wiring harnesses by operators. The plane of the fixing area 53 of the fixing bracket 50 can be parallel to the height direction H of the energy storage container 10, so that when the liquid cooling pipes 101 and wiring harnesses are arranged along the height direction H of the energy storage container 10, it is convenient to fix them in multiple fixing areas 53. In addition, as mentioned above, the liquid cooling pipes 101 fixed on the fixing bracket 50 can be secondary pipes 1012 included in the liquid cooling pipes 101, and the wiring harnesses fixed on the fixing bracket 50 can be high-voltage wiring and / or low-voltage wiring connected to the energy storage unit 20.

[0103] The fixing bracket 50 can be fixed only between the bottom frame 31 and the top frame 32. Alternatively, it can be fixedly connected to the corresponding inner frame 40 to further ensure its stability. For example, the fixing bracket 50 may also be fixedly connected to the vertical beam 41 of the corresponding inner frame 40, or to the fixed guide rail 42 of the corresponding inner frame 40.

[0104] In some implementations, the inner frame 40 described above is used, such as Figure 7 As shown, the vertical beam 41 is fixed with fixed guide rails 42 on both sides in the width direction Y of the energy storage container 10; in the width direction Y of the energy storage container 10, the fixed bracket 50 is located between the two fixed guide rails 42 included in the corresponding inner frame 40.

[0105] This facilitates the insertion of the fixed bracket 50 between the two fixed guide rails 42, thereby reducing the size of the energy storage container 10 in the depth direction S while fixing the liquid cooling pipeline 101 and the wiring harness, thus ensuring the miniaturization design of the energy storage container 10.

[0106] For example, for the plug-in design of the fixed bracket 50 and the corresponding inner frame 40, the fixed bracket 50 can extend between the two fixed guide rails 42 included in the inner frame 40 and be fixedly connected to the adjacent vertical beam 41, thereby ensuring the stability of the fixed bracket 50 structure.

[0107] In this embodiment, the fixing bracket 50 can be a flat bracket to fix the liquid cooling pipeline 101 and the wiring harness; of course, if... Figure 7As shown, the fixed support 50 may also include a fixed column 51 and multiple fixed plates 52; the two ends of the fixed column 51 are fixedly connected to the bottom frame 31 and the top frame 32 respectively, and the multiple fixed plates 52 are all fixedly connected to the fixed column 51 and are distributed at intervals along the length direction of the fixed column 51 (i.e. the height direction H of the energy storage container 10), and each fixed plate 52 forms a fixed area 53.

[0108] Thus, by setting up the fixed column 51 and multiple fixed plates 52, it is easy to simplify the fixing of the fixed bracket 50 between the bottom frame 31 and the top frame 32, so as to improve the assembly efficiency and assembly stability of the fixed bracket 50.

[0109] The surface of the fixing plate 52 is parallel to the height direction H of the energy storage container 10, so as to form a fixing area 53 through the surface of the fixing plate 52. Combined with the fixed connection between the fixing bracket 50 and the inner frame 40 described above, it can be as follows: Figure 7 As shown, multiple fixing plates 52 are fixedly connected to the corresponding inner frame 40 (i.e., both ends of each fixing plate 52 are fixedly connected to the fixing column 51 and the corresponding inner frame 40, respectively). For example, depending on the specific structure of the inner frame 40, multiple fixing plates 52 may be fixedly connected to the vertical beams 41 included in the corresponding inner frame 40.

[0110] In some implementations, such as Figure 7 As shown, the end of the fixing plate 52 near the inner frame 40 (that is, the end away from the fixing column 51) has an outward flap 523, which is fixedly connected to the vertical beam 41 included in the inner frame 40.

[0111] Thus, by setting the outer flap 523 on the fixing plate 52, it is easy to increase the fixing area 53 between the fixing plate 52 and the vertical beam 41, thereby improving the reliability of the fixed connection between the fixing plate 52 and the inner frame 40.

[0112] Furthermore, an outward-flaring plate 523 can also be provided at the end of the fixing plate 52 near the fixing post 51, and this outward-flaring plate is fixedly connected to the fixing post 51. In this way, the fixing area 53 between the fixing plate 52 and the fixing post 51 can be increased, thereby improving the reliability of the fixed connection between the fixing plate 52 and the fixing post 51.

[0113] In some embodiments, the end face of the fixing post 51 is bent, and one end of the fixing plate 52 abuts against the inside of the bend angle on the fixing post 51.

[0114] Thus, by abutting the fixed plate 52 on the inside of the bend angle on the fixed column 51, it is not only easy to increase the fixing area 53 of the fixed plate 52 and the fixed column 51, but also to achieve the pre-positioning of the fixed column 51 based on the fixed plate 52 after the fixed plate 52 is fixedly connected to the inner frame 40, thereby improving the assembly efficiency of the fixed column 51 with the bottom frame 31 and the top frame 32.

[0115] In some implementations, such as Figure 5 and Figure 8 As shown, the fixed column 51 has a bend 511 on the edge near the corresponding inner frame 40 in the area corresponding to each fixed plate 52. Each bend 511 has a positioning notch 512, and each fixed plate 52 is limited within the corresponding positioning notch 512.

[0116] Thus, by setting the bend 511 on the fixed post 51, the fixed plate 52 and the fixed post 51 can be positioned together based on the positioning notch 512 on the bend 511, thereby improving the connection efficiency between the fixed plate 52 and the fixed post 51; at the same time, based on the support of the fixed plate 52 in the notch 512, the reliability of the fixed connection between the fixed plate 52 and the fixed post 51 is improved, thereby ensuring the reliability of the liquid cooling pipeline 101 and the wiring harness.

[0117] The fixed column 51 can be U-shaped at the location where the bending part 511 is provided; of course, the fixed column 51 can also be U-shaped as a whole, that is, the fixed column 51 has an integral and continuous bending part 511 on the overall edge near the corresponding inner frame 40.

[0118] In some embodiments, multiple fixing plates 52 correspond one-to-one with multiple fixing rails 42, and each fixing plate 52 and its corresponding fixing rail 42 are offset in the height direction H of the energy storage container 10.

[0119] Thus, by setting multiple fixing plates 52, it is convenient to fix the liquid cooling pipes 101 and the wiring harness at a position close to each fixing guide rail 42; at the same time, based on the staggered setting of the fixing plates 52 and the corresponding fixing guide rails 42, it is convenient to form a large assembly space around the fixing plates 52, avoid interference from the fixing guide rails 42, thereby improving the fixing efficiency of the liquid cooling pipes 101 and the wiring harness.

[0120] The fixing plate 52 can be located on the side of the corresponding fixing guide rail 42 closer to the top frame 32, or it can be located on the side of the corresponding fixing guide rail 42 away from the top frame 32. When the fixing plate 52 is located on the side of the corresponding fixing guide rail 42 closer to the top frame 32, if the water inlet and outlet of the cooling plate of the energy storage unit 20 are located outside the box, a three-stage pipeline 1013 can be led out from the position near the fixing plate 52 and bent towards the bottom frame 31, thereby ensuring the reliability of the connection between the three-stage pipeline 1013 and the two-stage pipeline 1012.

[0121] In some implementations, such as Figure 7As shown, the fixing plate 52 has a plurality of fixing holes 524 extending through the width direction Y of the energy storage container 10, and the plurality of fixing holes 524 are spaced apart along the depth direction S of the energy storage container 10.

[0122] In this way, a first fixing position can be formed through the fixing hole 524, and then threaded cable ties, rivets, etc. can be wrapped around the first component to be fixed (such as secondary pipeline 1012 or wire harness routing) and fixed in the fixing hole 524, so as to simplify the fixing method of the first component to be fixed and improve the fixing efficiency of the first component to be fixed.

[0123] Taking the secondary pipeline 1012 as the first component to be fixed, it includes an inlet pipeline and an outlet pipeline. The inlet and outlet pipelines can be fixed in the fixing area 53 via two fixing holes 524. Furthermore, the fixing holes 524 on the fixing plate 52 can be two, three, four, etc., to adjust the fixing position of the first component to be fixed through different fixing holes 524, thereby ensuring reliable fixing of the first component in multiple fixing areas 53.

[0124] In some implementations, such as Figure 7 As shown, the fixing plate 52 includes a body plate 521 and a pair of upright plates 522 connected to the body plate 521 and arranged opposite to each other; the body plate 521 has a through hole 525 extending through the width direction Y of the energy storage container 10, and a pair of upright plates 54 arranged opposite to each other around the through hole 525; a connecting column 526 is provided between the pair of upright plates 54, and the connecting column 526 is arranged opposite to the through hole 525 in the axial direction of the through hole 525.

[0125] In this way, a second fixing position can be formed by connecting post 526, and then the second component to be fixed (such as secondary pipeline 1012 or wire harness routing) can be fixed on connecting post 526 by using binding materials such as cable ties. The through hole 525 provides operable space, thereby simplifying the fixing method of the second component to be fixed and improving the fixing efficiency of the second component to be fixed.

[0126] Taking the second component to be fixed as a wire harness as an example, the high-voltage wires and / or low-voltage wires can be fixed to the connecting post 526 by binding. Additionally, a pair of upright plates 54 are located on both sides of the through hole 525 along the height direction H of the energy storage container 10, to ensure that the length direction of the connecting post 526 is parallel to the height direction H of the energy storage container 10, that is, to ensure that the length direction of the connecting post 526 is parallel to the length direction of the wire harness. This avoids friction between the wire harness and the binding component when binding the wire harness, extending the service life of the wire harness.

[0127] The connecting post 526 between a pair of upright plates 54 can be one or more, in which case... Figure 7As shown, multiple connecting posts 526 are spaced apart along the depth direction S of the energy storage container 10, and at least one connecting post 526 is directly opposite the through hole 525 in the axial direction of the through hole 525. Thus, by using multiple connecting posts 526, the fixing position of the second component to be fixed can be adjusted based on different connecting posts 526, thereby preventing the second component to be fixed from bending, while ensuring reliable fixing of the second component in multiple fixing areas 53.

[0128] It should be noted that, in conjunction with the aforementioned case where the fixing area 53 is equipped with fixing holes 524 and connecting posts 526, the connecting posts 526 can be located on the side away from the inner frame 40. Taking the secondary pipeline 1012 as the first component to be fixed based on the fixing holes 524 and the wire harness as the second component to be fixed based on the connecting posts 526 as an example, in the depth direction S of the energy storage container 10, the wire harness can be located on the front side of the front end of the energy storage unit 20, thereby facilitating the connection of the wire harness connectors to the front end of the energy storage unit 20, while avoiding friction between the wire harness and the energy storage unit 20, which could cause damage to the wire harness.

[0129] 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.

[0130] The electrical equipment 510 is electrically connected to the energy storage device 100. Thus, in conjunction with the above description, during use, the power supply system 500 of this application, based on the stability of the energy storage container 10 in fixing the liquid cooling pipeline 101 and the wiring harness, ensures the safety of charging and discharging of the energy storage unit 20 while guaranteeing the reliability of the power supply from the energy storage device 100 to the electrical equipment 510.
