Description

Technical Field

[0001] This disclosure relates to the field of energy storage equipment design technology, and in particular to an energy storage container. Background Technology

[0002] Nowadays, with the rapid development of new energy power generation technology, energy storage containers are widely used in many fields such as industrial power distribution and public power consumption.

[0003] Currently, energy storage containers typically consist of a container body, multiple battery clusters, and a combiner cabinet. The multiple battery clusters are arranged horizontally at intervals inside the container body, and the combiner cabinet is located on the far left or far right of the multiple battery clusters. Each battery cluster is electrically connected to the combiner cabinet via a high-voltage power line.

[0004] However, for the above structure, the spacing between the battery clusters at both ends is relatively large. This means that when using high-voltage power lines of the same length for connection, most of the high-voltage power lines corresponding to the battery cluster closest to the combiner cabinet will be redundant inside the container, resulting in messy wiring in the energy storage container.

[0008] The plurality of battery clusters are respectively located in the first installation area, and the plurality of battery clusters are distributed in a horizontal direction;

[0009] The at least one combiner cabinet is located in the second installation area, and each combiner cabinet is electrically connected to a portion of the plurality of battery clusters.

[0016] The disconnect switch is located inside the housing;

[0017] The first connector is located inside the housing, and the first connector is electrically connected to a portion of the plurality of battery clusters;

[0018] The second connector is located inside the housing and is electrically connected to the energy storage converter;

[0019] The control unit is used to control the operating state of the disconnecting switch so that the plurality of battery clusters are disconnected or connected to the energy storage converter.

[0020] In one possible implementation, the first connector includes a first connecting bar and a plurality of first connecting terminals. The first connecting bar is fixedly connected to the housing and is electrically connected to the disconnect switch.

[0057] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0058] Currently, with the rapid development of new energy power generation technology, energy storage containers are widely used in various fields such as industrial power distribution and public power supply. An energy storage container typically consists of a container body, multiple battery clusters, and a combiner cabinet. Multiple battery clusters are arranged horizontally at intervals inside the container, with the combiner cabinet located on the far left or far right of the battery clusters. Each battery cluster is electrically connected to the combiner cabinet via a high-voltage power line. To improve the assembly efficiency of the energy storage container, high-voltage power lines of uniform length are typically used to connect the battery clusters and the combiner cabinet. In related technologies, a single combiner cabinet is installed on the side of a row of battery clusters. To meet the connection needs of the battery cluster furthest from the combiner cabinet, the battery cluster closest to the combiner cabinet also needs to be connected using a longer high-voltage power line. This results in a large amount of redundancy in the high-voltage power line within the container, leading to messy wiring. Technicians performing maintenance on the energy storage container may trip over this redundancy, posing a safety hazard.

[0059] To address the aforementioned problems, embodiments of this disclosure provide an energy storage container, such as... Figure 1 As shown, the energy storage container includes a container body 1, multiple battery clusters 2 and at least one combiner cabinet 3.

[0060] The housing 1 has a first installation area 11 and a second installation area 12 inside. The second installation area 12 is located below the first installation area 11. Multiple battery clusters 2 are located in the first installation area 11 and are distributed horizontally. At least one combiner cabinet 3 is located in the second installation area 12 and each combiner cabinet 3 is electrically connected to a portion of the multiple battery clusters 2.

[0061] Using the technical solution provided in this disclosure, in an energy storage container, at least one combiner cabinet 3 is arranged below multiple battery clusters 2. Compared with the related technology (energy storage container) which only includes one combiner cabinet and is arranged to the side of multiple battery clusters 2, each combiner cabinet 3 can be electrically connected to several adjacent battery clusters 2, so that the distance difference between each combiner cabinet 3 and different battery clusters 2 is small. Even if high-voltage power lines of the same length are used to connect the combiner cabinet 3 and the corresponding battery clusters 2 respectively, each high-voltage power line will not be too redundant, which can avoid redundant and messy wiring inside the container, thereby reducing the safety hazards when maintaining the energy storage container.

[0062] The following section will introduce each part of the energy storage container. It should be noted that the inputs and outputs mentioned below are all based on the energy storage container as a load and the grid as the power supply.

[0063] I. Box 1

[0064] The container 1 is a component in the energy storage container used to house multiple battery clusters 2 and at least one combiner cabinet 3.

[0065] like Figure 1 As shown, the box 1 has a hollow cubic structure, and the box 1 has a first installation area 11 and a second installation area 12 inside, and the first installation area 11 and the second installation area 12 are distributed at intervals along the vertical direction.

[0066] The first installation area 11 accommodates multiple battery clusters 2, and the second installation area 12 accommodates at least one combiner cabinet 3.

[0067] For example, the container 1 in the energy storage container is typically a 20-foot container, with specific dimensions of 6.06 meters long × 2.44 meters wide × 2.59 meters high.

[0068] In some possible embodiments, the energy storage container also includes a mounting rack 4.

[0069] like Figure 2 As shown, mounting bracket 4 is located inside housing 1, and mounting bracket 4 is fixedly connected to housing 1. Specifically, see [link to documentation]. Figure 2 A first mounting area 11 is formed between the mounting bracket 4 and the top wall of the housing 1, and a second mounting area 12 is formed between the mounting bracket 4 and the bottom wall of the housing 1. Further, as... Figure 2 and Figure 3 As shown ( Figure 3 (This is a schematic diagram of the structure of a mounting frame 4 provided in an embodiment of the present disclosure). The mounting frame 4 includes a horizontal plate, multiple vertical plates, and multiple support members. The multiple vertical plates are located above the horizontal plate, are parallel to each other, and are connected to the horizontal plate at one end. The multiple support members are located above the horizontal plate, are parallel to each other, and are connected to the horizontal plate at one end. A first accommodating space is formed between the horizontal plate, two adjacent vertical plates, and the top wall of the housing 1, and each accommodating space accommodates a battery cluster 2. A second accommodating space is formed between the horizontal plate, two adjacent vertical plates, and the bottom wall of the housing 1, and each second accommodating space accommodates a combiner cabinet 3.

[0070] In some examples, such as Figure 3 As shown, the mounting bracket 4 has a clearance hole 41, which connects the first mounting area 11 and the second mounting area 12. The clearance hole 41 is used for the wiring harness of the power supply connection between the combiner cabinet 3 and the battery cluster 2 to pass through. See specifically... Figure 3The mounting bracket 4 has a clearance hole 41 on its horizontal plate, which extends through the upper and lower surfaces. This clearance hole 41 connects the first accommodating space and the second accommodating space, that is, it connects the first mounting area 11 and the second mounting area 12. In practice, one end of the high-voltage power line is connected to the battery cluster 2, and the other end of the high-voltage power line can pass through the clearance hole 41 and connect to the combiner cabinet 3.

[0071] For example, the above-mentioned wire harness is a high-voltage power line with a cross-sectional area of ​​70 square millimeters.

[0072] For example, the shape of the clearance hole 41 can be square. Of course, the shape of the clearance hole 41 can also be circular, elliptical, etc., and those skilled in the art can set it according to actual needs. This disclosure does not limit it in this respect.

[0073] II. Battery Cluster 2

[0074] Battery cluster 2 is the energy storage component in the energy storage container.

[0075] In some possible embodiments, the battery cluster 2 includes a plurality of battery packs 21 and a high-voltage box 22.

[0076] like Figure 8 As shown, the battery cluster 2 includes multiple battery packs 21 and a high-voltage box 22. The multiple battery packs 21 are distributed vertically. Each battery pack 21 has a positive terminal and a negative terminal. Multiple wire harnesses are connected to the positive terminal and negative terminal of two adjacent battery packs 21 respectively, so that the multiple battery packs 21 are connected in series. The positive terminal of the uppermost battery pack 21 is connected to the positive input terminal of the high-voltage box 22 through a wire harness, and the negative terminal of the lowermost battery pack 21 is connected to the negative input terminal of the high-voltage box 22 through a wire harness.

[0077] Further, see Figure 8 The negative output terminal of the high-voltage box 22 is connected to the negative input terminal of the combiner cabinet 3, and the positive output terminal of the high-voltage box 22 is connected to the positive input terminal of the combiner cabinet 3.

[0078] In some examples, the number of battery packs 21 in each battery cluster is no less than five. This ensures that the energy storage container has sufficient energy storage density.

[0079] For example, the number of battery packs 21 in each battery cluster can be eight or nine.

[0080] III. Combiner Cabinet 3

[0081] Combiner cabinet 3 is a component in the energy storage container that centrally manages the DC power of the battery packs.

[0082] For example, the dimensions of the combiner cabinet 3 can be 0.76 meters long × 0.54 meters wide × 0.62 meters high.

[0083] like Figure 1 As shown, at least one junction box 3 is located in the second installation area 12 and is connected to the enclosure 1.

[0084] For example, the connection between the junction box 3 and the enclosure 1 can be a bolt connection.

[0085] In some possible embodiments, see Figure 9 The energy storage container includes a junction box 3 located in the second installation area 12, and the junction box 3 is equidistant from the battery clusters 2 on both sides.

[0086] In some possible embodiments, see Figure 1 The energy storage container includes multiple combiner cabinets 3, and each combiner cabinet 3 is electrically connected to the same number of battery clusters 2.

[0087] In one example, such as Figure 1 As shown, the energy storage container includes eight battery clusters 2 and two combiner cabinets 3, with each combiner cabinet 3 electrically connected to the other four combiner cabinets 3.

[0088] In implementation, the energy storage container also includes an energy storage converter 5, abbreviated as PCS (Power Conversion System), whose function is to convert AC power to DC power, or vice versa. See also Figure 5 The energy storage converter 5 is connected to multiple combiner cabinets 3 via wiring harnesses.

[0089] In practice, each combiner cabinet 3 will be connected in parallel with the DC output of multiple battery clusters 2 connected to it to form a unified DC bus to supply the energy storage converter 5.

[0090] In some possible embodiments, the combiner cabinet 3 includes a housing 31, a disconnect switch 32, a first connector 33, a second connector 34, and a control unit 35.

[0091] Specifically, such as Figure 5 As shown, the housing 31 includes a housing body and a door panel. The housing body is a hollow cubic structure with a front opening. The door panel has a rectangular structure, covers the front opening of the housing body, and is rotatably connected to the housing body. The disconnect switch 32 is fixed inside the housing 31. The first connector 33 is a component for connecting the battery cluster 2, see [reference needed]. Figure 4 See also Figure 5 The first connector 33 is connected to the disconnect switch 32 and multiple battery clusters 2 via wiring harnesses. The second connector 34 is a component of the energy storage converter 5, see [link to documentation]. Figure 4 See also Figure 5The second connector 34 is connected to the disconnector switch 32 and the energy storage converter 5 via wiring harnesses. The control unit 35 is used to control the operating state of the disconnector switch 32, that is, to switch the disconnector switch 32 from the first operating state to the second operating state, or from the second operating state to the first operating state. The first operating state is called the closed state, in which the energy storage converter 5 is connected to the battery cluster 2. The second operating state is called the open state, in which the energy storage converter 5 is disconnected from the battery cluster 2.

[0092] Further reading is available upon request. Figure 4 The first connector 33 includes a first connecting bar 331 and a plurality of first connecting terminals 332. The first connecting bar 331 is fixedly connected to the housing 31 and is electrically connected to the disconnecting switch 32. One end of each first connecting terminal 332 is electrically connected to the first connecting bar 331, and the other end of each first connecting terminal 332 extends out of the housing 31 and is electrically connected to the battery cluster 2. The second connector 34 includes a second connecting bar 341 and a plurality of second connecting terminals 342. The second connecting bar 341 is fixedly connected to the housing 31 and is electrically connected to the disconnecting switch 32. One end of each second connecting terminal 342 is electrically connected to the second connecting bar 341, and the other end of each second connecting terminal 342 extends out of the housing 31 and is electrically connected to the energy storage converter 5.

[0093] For example, such as Figure 4 As shown, the first connection bar 331 includes a first negative connection bar 331a and a first positive connection bar 331b. The first negative connection bar 331a and the first positive connection bar 331b are respectively fixed to the back wall of the housing 31 and are electrically connected to the disconnecting switch 32. (Reference) Figure 8 The first connection terminal 322 includes a plurality of first negative connection terminals 332a and a plurality of first positive connection terminals 332b. One end of each first negative connection terminal 332a is connected to the negative output terminal of a high-voltage box 22 via a wire harness, and the other end of each first negative connection terminal 332a is fixedly connected to a first negative connection bar 331a. One end of each first positive connection bar 331b is connected to the positive output terminal of a high-voltage box 22 via a wire harness, and the other end of each first positive connection bar 331b is fixedly connected to a first positive connection bar 331b.

[0094] For example, see Figure 4 And refer to Figure 1Both the first negative terminal block 331a and the first positive terminal block 331b are copper busbars, each with a size of 80mm*6mm, and each has 6*M8 holes. The number of first negative terminal blocks 332a and first positive terminal blocks 332b are both four, meaning that the number of 6*M8 holes on both the first negative terminal block 331a and the first positive terminal block 331b is four.

[0095] For example, such as Figure 4 As shown, the second connection bar 341 includes a second negative connection bar 341a and a second positive connection bar 341b. The second negative connection bar 341a and the second positive connection bar 341b are respectively fixed to two opposite side walls of the housing 31 and are electrically connected to the disconnecting switch 32. See also Figure 4 The second connection terminal 342 includes a plurality of second negative connection terminals 342a and a plurality of second positive connection terminals 342b. One end of each second negative connection terminal 342a is connected to the negative input terminal of the energy storage converter 5 via a wire harness, and the other end of each second negative connection terminal 342a is fixedly connected to the second negative connection bar 341a. One end of each second positive connection bar 341b is connected to the positive input terminal of the energy storage converter 5 via a wire harness, and the other end of each second positive connection bar 341b is fixedly connected to the second positive connection bar 341b.

[0096] For example, see Figure 4 And refer to Figure 1 Both the second negative terminal 341a and the second positive terminal 341b are copper busbars, each with a size of 80mm*6mm, and each has 7*M8 holes pre-drilled. There are four second negative terminal 342a and four second positive terminal 342b, meaning that there are four 7*M8 holes on each of the second negative terminal 342a and the second positive terminal 342b.

[0097] Optionally, the combiner cabinet 3 is also equipped with fuses and surge protectors.

[0098] Optionally, the combiner unit 3 may also include an operating element 36.

[0099] like Figure 4 As shown, the operating component 36 is fixed to the outside of the door panel of the housing 31. Technicians can manually move the operating component 36 to control the working state of the disconnect switch 32 through the control unit 35.

[0100] In some possible embodiments, each combiner cabinet 3 is located below the corresponding target battery cluster.

[0101] The target battery cluster is located in the middle of the multiple battery clusters 2 connected to the combiner cabinet 3.

[0102] In implementation, each combiner cabinet 3 is electrically connected to multiple battery clusters 2. When the number of battery clusters 2 connected to each combiner cabinet 3 is odd, the target battery cluster is the battery cluster 2 located in the middle. When the number of battery clusters 2 connected to each combiner cabinet 3 is even, the target battery clusters are the two battery clusters 2 located in the middle position.

[0103] This can further reduce the distance difference between each combiner cabinet 3 and different battery clusters 2, thereby further reducing the redundancy of the high-voltage power lines connecting the combiner cabinet 3 and the battery clusters 2.

[0104] In some possible embodiments, the energy storage container also includes a battery management system 6, which is a component in the energy storage container used to detect the operating status of each battery cluster 2.

[0105] like Figure 6 As shown, the battery management system 6 is located on the outside of the housing 1 and is fixedly connected to the housing 1.

[0106] In implementation, each battery cluster 2 can integrate a sub-battery management unit inside its high-voltage box 22. Each sub-battery management unit is used to detect the voltage and temperature signals of multiple battery packs 21 connected in series with the high-voltage box 22. The battery management system 6 is electrically connected to multiple sub-battery management units, thereby realizing the detection of the voltage and temperature of all battery packs.

[0107] In one example, see Figure 6 The battery management system 6 is communicatively connected to the control unit 35 in each combiner cabinet 3. Thus, when the operating status of the combiner cabinet 3 needs to be adjusted, technicians can operate the battery management system 6 from outside the enclosure 1, sending operation instructions to the control unit 35 in each combiner cabinet 3. These instructions trigger the control unit 35 to switch the operating status of the corresponding isolating switch 32, thereby controlling the closing or opening of each combiner cabinet 3. Technicians do not need to enter the enclosure 1, improving operational convenience.

[0108] In some possible embodiments, the energy storage container also includes an uninterruptible power supply (UPS), which is a component in the energy storage container that provides emergency power to ensure system safety. See also Figure 7 The uninterruptible power supply 7 is located inside the housing 1 and is electrically connected to the battery management system 6.

[0109] In practice, when the main power supply fails, the uninterruptible power supply 7 can instantly switch its operating state and provide power to the battery management system 6. Optionally, the energy storage container also includes a cooling system, to which the uninterruptible power supply 7 can be electrically connected. This ensures that the cooling system continues to operate when the main power supply fails, preventing risks such as thermal runaway caused by the energy storage container shutting down.

[0110] The technical solution provided in this disclosure includes at least the following beneficial effects:

[0111] This disclosure provides an energy storage container in which multiple combiner cabinets 3 are arranged below multiple battery clusters 2. Compared with the related technology (energy storage container) which only includes one combiner cabinet and is arranged to the side of multiple battery clusters 2, each combiner cabinet 3 can be electrically connected to several adjacent battery clusters 2, so that the distance difference between each combiner cabinet 3 and different battery clusters 2 is small. Even if high-voltage power lines of the same length are used to connect the combiner cabinet 3 and the corresponding battery cluster 2 respectively, each high-voltage power line will not be too redundant, which can avoid redundant and messy wiring inside the container, thereby reducing the safety hazards when maintaining the energy storage container.
