Description

Technical Field

[0001] The present application relates to the field of energy storage technology, and in particular to an energy storage container and an energy storage container system. Background Art

[0002] With the large-scale application of new energy power generation, electrochemical energy storage (for example, lithium battery energy storage) has been widely promoted. Energy storage containers are highly favored due to their high degree of modularity, easy transportation and installation, etc. Energy storage containers can effectively solve problems such as energy storage and energy supply.

[0003] In the related art, the components in the energy storage container will interfere with each other during operation, affecting the normal operation of the components themselves, and also causing the energy storage container to have greater safety hazards. Utility Model Content

[0004] The present application provides an energy storage container, and an energy storage container system including the energy storage container. By separating a plurality of compartments with different functions in the container body, the possibility of mutual influence among components in the energy storage container is reduced, making the energy storage container safer and more stable during operation.

[0005] In order to achieve the above objectives, this application adopts the following technical solutions:

[0006] In a first aspect of the present application, an energy storage container is provided, which includes a box body and a temperature control compartment, a battery compartment and a power distribution compartment arranged adjacent to each other in the length direction of the box body; wherein the temperature control compartment is used to accommodate a liquid cooling unit for dissipating heat for the battery compartment; the battery compartment includes multiple columns of battery clusters, which are arranged side by side along the length direction of the box body, and each column of the multiple columns of battery clusters includes multiple battery packs stacked along the height direction of the box body; a controller for controlling the multiple columns of battery clusters is provided in the power distribution compartment, the multiple columns of battery clusters are electrically connected to the controller through multiple first power lines, the controller is electrically connected to multiple second power lines for current input or output, and the box body is provided with a first line port connected to the power distribution compartment, and multiple second power lines extend out of the box body through the first line port.

[0007] The energy storage container of the present application has three independent compartments (temperature control compartment, battery compartment and power distribution compartment), and the temperature control compartment, battery compartment and power distribution compartment are respectively provided with a liquid cooling unit, a battery cluster and a controller. If the temperature of the battery compartment is too high, it will shorten the life of the battery pack and increase the risk of thermal runaway of the battery pack. The battery cluster is cooled by the liquid cooling unit so that the battery cluster can operate stably and normally. The liquid cooling unit and the battery cluster are respectively arranged in two separate compartments (temperature control compartment and battery compartment), so that the liquid cooling unit can operate better in an independent compartment, reducing the impact of the liquid cooling unit on the battery cluster during operation.

[0008] When the energy storage container is discharged, the current in the battery cluster flows to the controller through the first power line, and then outputs to the outside through the second power line on the controller. When the energy storage container is charged, the external current flows to the controller through the second power line, and then inputs the battery cluster through the first power line. The controller plays at least one of the following roles for the battery cluster: overload protection, monitoring and control, and load regulation. The controller is set in the power distribution warehouse, so that the controller and the battery cluster are respectively located in two separate compartments (the power distribution warehouse and the battery warehouse are independent warehouses), which reduces the safety risks during the operation of the energy storage container.

[0009] In addition, the energy storage container needs to be connected to the outside (for example, the second power line, some signal lines, etc.), and some cables inside the box need to extend out of the box. The cables that need to be extended are concentrated in the distribution warehouse and then extended from the distribution warehouse. Since the distribution warehouse is located on one side of the box, it is convenient for the layout of cables and it is easy to realize the external connection of the energy storage container.

[0010] In an optional embodiment, an auxiliary distribution cabinet for supplying power to the liquid cooling unit is provided in the distribution bin, the auxiliary distribution cabinet and the controller are arranged along the width direction of the box body, the auxiliary distribution cabinet is electrically connected to a third power line for connecting to an external power supply, the box body is provided with a second line port connected to the distribution bin, and the third power line extends out of the box body through the second line port.

[0011] The auxiliary power distribution cabinet can supply power to the liquid cooling unit (or other components in the energy storage container) through the third power line external power supply, so that the liquid cooling unit can operate stably. The power distribution warehouse is an independent warehouse with a large space. The auxiliary power distribution cabinet is set in the power distribution warehouse to facilitate the placement of the auxiliary power distribution cabinet. In addition, the third power line on the auxiliary power distribution cabinet needs to extend out of the box and connect to the external power supply. The power distribution warehouse is located on one side of the box, which is conducive to the external connection of the auxiliary power distribution cabinet.

[0012] In an optional implementation, the first wire passing opening and the second wire passing opening are both located at the bottom of the box.

[0013] The first and second wire ports are arranged at the bottom of the box, which reduces the possibility of foreign matter entering the power distribution compartment and protects the components in the power distribution compartment. In addition, the second power line and the third power line extend from the bottom of the box, so that the first power line and the second power line extending from the box are close to the ground, which is convenient for arranging and fixing the cables extending from the energy storage container from the outside.

[0014] In an optional embodiment, a fire extinguisher and a fire host for controlling the fire extinguisher are provided in the distribution compartment, and the auxiliary distribution cabinet supplies power to the fire host and the fire extinguisher. A fire pipe is connected to the fire extinguisher, and the fire pipe extends into the battery compartment and is located above multiple columns of battery clusters. A plurality of nozzles located in the battery compartment are provided on the wall of the fire pipe.

[0015] The auxiliary power distribution cabinet can supply power to the fire host and the fire extinguisher, and the fire host controls the fire extinguisher to output the fire extinguishing agent. When a fire occurs in the battery compartment (for example, a battery pack thermal runaway fire or explosion), the fire extinguishing agent in the fire extinguisher flows into the battery compartment through the fire hose and is ejected from the nozzle on the fire hose. The ejected fire extinguishing agent falls from above the battery cluster to extinguish the fire in the battery compartment, reducing the possibility of further spread of the fire in the battery compartment and reducing the risk of explosion of the energy storage container.

[0016] In an optional implementation, the fire extinguisher and the fire host are both arranged above the auxiliary distribution cabinet.

[0017] The input and output of the first power line and the second power line are strong current, and the auxiliary distribution cabinet, fire extinguisher and fire host are weak current equipment. The fire extinguisher and fire host are placed above the energy storage distribution cabinet to separate the auxiliary distribution cabinet, fire extinguisher and fire host from the controller, that is, to divide the distribution warehouse into strong current area and weak current area, reducing the possibility of strong current interfering with weak current in the distribution warehouse. In addition, strong current lines may have a high risk of electric shock and fire. Separating strong current and weak current can reduce the occurrence of such risks and facilitate safe and compliant wiring in the distribution warehouse.

[0018] In an optional embodiment, a first partition for separating the battery compartment and the power distribution compartment is provided in the box body, a first opening is provided on the first partition, and a plurality of first power lines extend from the battery compartment into the power distribution compartment through the first opening.

[0019] The battery compartment and the power distribution compartment are separated by the first partition, which reduces the possibility of the battery compartment and the power distribution compartment affecting each other. A first opening is arranged on the first partition to facilitate the first power line to extend from the battery compartment into the power distribution compartment.

[0020] In an optional embodiment, the first opening is located at the bottom of the first partition.

[0021] The first through hole is arranged at the bottom of the first partition, and the first power line can extend from the bottom of the battery compartment into the power distribution compartment, so that the first power line can share space with the pipe at the bottom of the battery compartment (for example, the pipe of the liquid cooling component extending into the battery compartment) or the wiring at the bottom of the battery compartment, thereby improving the space utilization at the bottom of the battery compartment, allowing more space in the battery compartment to arrange the battery cluster, and improving the energy density of the energy storage container.

[0022] In an optional embodiment, the controller includes multiple battery cluster control boxes arranged along the width direction of the box body, the number of battery cluster control boxes is the same as the number of columns of battery clusters, multiple battery packs in each column of battery clusters are connected in series, each column of battery clusters is electrically connected to the corresponding battery cluster control box through two first power lines, and two second power lines are connected to the bottom of each battery cluster control box.

[0023] Each battery cluster control box controls a column of battery clusters, so that each column of battery clusters can be accurately monitored and controlled. The controller can control and adjust the corresponding battery cluster through the corresponding battery cluster control box. When the energy storage container is discharged, the current in each column of battery clusters is input to the corresponding battery cluster control box through two first power lines, and output from the two second power lines connected to the battery cluster control box (the output from the battery cluster control box is direct current).

[0024] In an optional embodiment, the controller includes multiple energy storage inverters arranged along the width of the box, the number of the energy storage inverters is the same as the number of columns of battery clusters, the multiple battery packs in each column of battery clusters are connected in series, and each column of battery clusters is electrically connected to the corresponding energy storage inverter through two first power lines. The bottom of each energy storage inverter is connected to multiple second power lines for outputting alternating current.

[0025] The Power Conversion System (PCS) consists of a DC / AC bidirectional converter, a control unit, etc. It can control the charging and discharging of the battery cluster, perform AC and DC conversion, etc. Each energy storage converter corresponds to a column of battery clusters, so that each column of battery clusters can be accurately monitored and controlled. In addition, when the energy storage container is discharged, AC power is directly output from the energy storage converter without the need to convert the current output from the second power line.

[0026] In an optional embodiment, the box body includes a first side wall and a second side wall arranged along the length direction of the box body, and a third side wall and a fourth side wall arranged along the width direction of the box body, the first side wall, the second side wall, the third side wall and the fourth side wall enclose the internal space of the box body, and the distribution compartment is formed between the first partition and the first side wall, and the first side wall includes a first door body, which is used to open or close the distribution compartment.

[0027] The first side wall, the second side wall, the third side wall and the fourth side wall protect the components in the box to prevent the external environment from affecting the normal operation of the components in the box. The power distribution warehouse is formed between the first partition and the first side wall. The first side wall includes a first door body. The first door body can open or close the power distribution warehouse, which is convenient for the staff to inspect the components in the power distribution warehouse and also convenient for the staff to connect the wires in the power distribution warehouse.

[0028] In an optional embodiment, a second partition for separating the battery compartment and the temperature control compartment is provided in the box body, the second partition and the first partition are arranged along the length direction of the box body, the temperature control compartment is formed between the second side wall and the second partition, a second opening is provided at the bottom of the second partition, and a liquid cooling pipe is connected to the liquid cooling unit, and the liquid cooling pipe extends from the temperature control compartment through the second opening into the battery compartment.

[0029] The components of the temperature control compartment (e.g., the liquid cooling unit) and the components in the battery compartment (e.g., the battery cluster) are separated from each other by the second partition, which reduces the possibility of mutual influence and interference between the components in the energy storage container, making the energy storage container safer and more stable during operation. When the battery cluster needs to be cooled, the liquid cooling unit can transport the cooling medium (e.g., cooling water) to the battery compartment through the liquid cooling pipe, so that the cooling medium exchanges heat with the battery cluster in the battery compartment, that is, cools the battery cluster, and the cooling medium after heat exchange returns to the liquid cooling unit through the liquid cooling pipe.

[0030] In an optional embodiment, the liquid cooling pipe extends from the temperature control compartment through the battery compartment and into the power distribution compartment.

[0031] When the power distribution warehouse needs to be cooled, the liquid cooling unit can transport the cooling medium to the power distribution warehouse through the liquid cooling pipe, so that the cooling medium exchanges heat in the power distribution warehouse, and the cooling medium after heat exchange returns to the liquid cooling unit through the liquid cooling pipe. When the liquid cooling pipe extends into the battery warehouse and the power distribution warehouse, the battery warehouse and the power distribution warehouse are separated from each other but dissipate heat uniformly. On the basis of safe operation of the energy storage container, the heat dissipation of the battery warehouse and the power distribution warehouse is taken into account, and a higher volume utilization rate in the box is achieved.

[0032] In an optional embodiment, the liquid cooling unit includes a heat dissipation fan, at least one of the second side wall, the third side wall and the fourth side wall is provided with an air inlet connected to the temperature control chamber, and the top of the box body is provided with an air outlet connected to the temperature control chamber, and the air inlet, the temperature control chamber and the air outlet form an air passage.

[0033] Through the above design, the liquid cooling unit needs to exchange heat with the outside during operation. The temperature control chamber is located on one side of the box, and air inlets are set around the temperature control chamber so that more air around the box can be sucked into the temperature control chamber. The more gas sucked into the temperature control chamber, the better the heat exchange effect of the liquid cooling unit. The gas after heat exchange is discharged from the top outlet. The temperature control efficiency of the liquid cooling unit is improved, which is beneficial to the operation of the liquid cooling unit and can cool the battery cluster more effectively.

[0034] In an optional embodiment, at least one of the third side wall and the fourth side wall includes a second door body, the second door body is located between the first partition plate and the second partition plate, and the second door body is used to open or close the battery compartment.

[0035] The second door can be used by operators to open or close the battery compartment. When the battery cluster needs to be installed, replaced or repaired, the second door can be opened to perform the operation. When the battery cluster is running, closing the second door can protect the battery cluster, reduce the possibility of the external environment affecting the normal operation of the battery cluster, and enable the energy storage container of the present application to operate stably.

[0036] In an optional embodiment, the third side wall includes a second door body, and the fourth side wall includes a first box board and a first fireproof board, and the first fireproof board is connected to the wall surface of the first box board facing the internal space of the box body.

[0037] The second door body is only provided on one side of the box body, and the energy storage container is an energy storage container with a single-side door, so that two energy storage containers can be put together in a "back-to-back" manner, that is, when the two energy storage containers are put together, the third side walls of the two boxes are away from each other, and the fourth side walls of the two boxes are arranged oppositely. There is no need to open a door on one side of the fourth side wall, so that the distance between the two energy storage containers arranged "back to back" can be small, and short-distance box combination can be achieved. In order to prevent one of the energy storage containers from affecting the other energy storage container when it burns, the fourth side wall can include a first fireproof board, and the first fireproof board can reduce the impact of external flames on the energy storage container. When one energy storage container burns, the probability of another energy storage container set "back to back" with the burning energy storage container being ignited is small, which can shorten the safety distance between the two energy storage containers placed "back to back", further reduce the distance between the two adjacent energy storage containers after the box is combined, and reduce the floor space occupied by multiple energy storage containers.

[0038] In an optional embodiment, the first side wall includes a second box panel and a second fireproof panel, and the second fireproof panel is connected to the wall surface of the second box panel facing the internal space of the box body.

[0039] Two energy storage containers can be placed side by side in a "shoulder to shoulder" manner, that is, when the two energy storage containers are placed side by side along the length direction of the container body, the first side walls of the two energy storage containers are arranged relatively to each other. In order to prevent the burning of one of the energy storage containers from affecting the other energy storage container, the first side wall may include a second fireproof board. When one energy storage container burns, the other energy storage container placed "shoulder to shoulder" with the burning energy storage container is difficult to ignite under the protection of the second fireproof board. By setting the second fireproof board, the impact of external flames on the energy storage container can be reduced, and the safe distance between the two energy storage containers placed "shoulder to shoulder" can be made smaller, further reducing the distance between the two adjacent energy storage containers after the combination, and reducing the floor space occupied by multiple energy storage containers.

[0040] In an optional embodiment, a support frame for placing multiple rows of battery clusters is provided in the battery compartment, and the dimension of the support frame in the width direction of the box body is 1700 mm to 2200 mm.

[0041] The support frame is arranged in the box body, and multiple rows of battery clusters are installed on the support frame. The dimension of the energy storage container in the box width direction is usually about 2400mm. The dimension of the support frame in the box width direction of the present application is 1700mm~2200mm, that is, the dimension of the support frame in the box width direction is set larger, and a larger (or more) battery pack can be installed on the support frame, so that the battery pack is distributed deeper, and the internal space of the box is better utilized, so that the number of battery cells in the temperature control compartment is larger, and the energy density of the energy storage container is improved.

[0042] In a second aspect of the present application, an energy storage container system is provided, which includes a plurality of energy storage boxes, at least one of which is the above-mentioned energy storage container, and the plurality of energy storage boxes are arranged at intervals along the length direction of the box body, or the plurality of energy storage boxes are arranged at intervals along the width direction of the box body.

[0043] The energy storage container system provided in the present application includes the above-mentioned energy storage container. Therefore, the energy storage container system provided in the present application and the energy storage container of the above-mentioned technical solution can solve the same technical problems and have the same technical effects, which will not be repeated here.

In addition, when describing pipelines or channels, the "connected" and "connected" used in this application have the meaning of conduction. The specific meaning needs to be understood in conjunction with the context.

[0066] In addition, in this application, the words "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "exemplary" or "for example" in this application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0067] In the drawings of the embodiments of the present application, solid structures such as components and assemblies are represented by guide lines; hollow structures such as openings, holes, spaces, and cavities are represented by guide lines with arrows.

[0068] An energy storage container system 100 provided in an embodiment of the present application is referred to Figure 1 , Figure 1 The structure of the energy storage container system 100 is exemplarily shown (top view), and the energy storage container system 100 includes multiple energy storage boxes, at least one of which is an energy storage container 200. For example, the multiple energy storage boxes are all energy storage containers 200.

[0069] When the energy storage container 200 is placed at a designated location, the energy storage container 200 has a length direction, a width direction, and a height direction that are perpendicular to each other. The length direction of the energy storage container 200 may be the first direction shown in the drawings, the width direction of the energy storage container 200 may be the second direction shown in the drawings, the first direction and the second direction may both be parallel to the horizontal plane, and the height direction of the energy storage container 200 may be the gravity direction (or vertical direction).

[0070] In some examples, a plurality of energy storage containers 200 may be arranged at intervals along a first direction, for example Figure 1 In the arrangement shown in the dashed box A, there is a certain distance between two adjacent energy storage containers 200 in the first direction. In other examples, multiple energy storage containers 200 may also be arranged at intervals along the second direction, for example Figure 1In the arrangement shown in the dotted line box B, there is a certain distance between two adjacent energy storage containers 200. In some other examples, refer to Figure 1 , multiple energy storage containers 200 are distributed in a matrix.

[0071] The energy storage container 200 of the present application can be a power source with a container as a carrier, which realizes the storage and output of electric energy by converting electric energy and chemical energy. The energy storage box in the form of a container is easy to transport, so that the energy storage container 200 can be quickly and conveniently transported from the production side to the user side, and placed in a designated usage scenario. The energy storage container 200 can effectively solve the energy storage and supply problems.

[0072] The energy storage container 200 can be used in industrial and commercial energy storage scenarios or power station energy storage scenarios. Industrial and commercial energy storage scenarios can be large factories, small factories, commercial office buildings, stations and other scenarios. The power granularity of power station energy storage scenarios is generally at the megawatt-hour level, which is commonly used for photovoltaic and wind power storage.

[0073] The present application embodiment provides an energy storage container 200, referring to Figure 2 , Figure 2 The structure of the energy storage container 200 is shown as an example. The energy storage container 200 includes a box body 1, which can be a container. For example, the box body 1 is a container that meets international standards, a container that meets regional standards, etc. Transporting in the form of a container has the advantages of high standardization, good sealing, and low damage rate, which can improve the safety and efficiency of transporting the energy storage container 200 and reduce transportation costs.

[0074] The size of the box 1 can be selected according to the needs. For example, the box 1 can be a 20-foot container, a 40-foot container, or a container of other specifications to meet the needs of different scenarios. This application does not impose specific restrictions on this. The example energy storage container 200 can be stacked in the vertical direction, that is, one energy storage container 200 can be stacked on top of another energy storage container 200, thereby meeting the transportation needs.

[0075] In order to stably connect two adjacent energy storage containers 200, refer to Figure 2 , a plurality of corner fittings 17 are provided on the box body 1. For example, the eight corners of the box body 1 are all provided with corner fittings 17, and two adjacent boxes 1 can be quickly and stably connected through the corner fittings 17, so that the adjacent energy storage containers 200 are more firmly connected to each other, and the stacking transportation of the energy storage containers 200 can be realized, thereby reducing the transportation cost.

[0076] In order to enable the components in the box 1 to operate in their respective spaces and avoid mutual influence between different components, refer to Figure 3 , Figure 3The distribution of the internal compartments of the box body 1 is shown as an example. The energy storage container 200 includes a temperature control compartment 101, a battery compartment 102, and a power distribution compartment 103 arranged adjacent to each other in the length direction (the first direction in the figure) of the box body 1. The temperature control compartment 101, the battery compartment 102, and the power distribution compartment 103 are separated from each other, that is, the internal space of the box body 1 is divided into three mutually separated compartments, and there is a clear boundary between two adjacent compartments.

[0077] The structure that serves as a boundary in the box body 1 can have many different forms. In one example, refer to Figure 3 The box body 1 is provided with a first partition 7 and a second partition 8 arranged along its length direction, the battery compartment 102 is formed between the first partition 7 and the second partition 8, the distribution compartment 103 is located on the side of the first partition 7 away from the battery compartment 102, and the temperature control compartment 101 is located on the side of the second partition 8 away from the battery compartment 102.

[0078] The internal space of the box body 1 is divided into at least three parts by the first partition 7 and the second partition 8, that is, at least a temperature control compartment 101, a battery compartment 102 and a power distribution compartment 103 are divided in the box body 1 by the first partition 7 and the second partition 8, so that the temperature control compartment 101, the battery compartment 102 and the power distribution compartment 103 are separated from each other, reducing the possibility of mutual influence of the components in the above three compartments.

[0079] In addition, the first partition plate 7 and the second partition plate 8 are used to divide the internal space of the box body 1, which can reduce the manufacturing cost of the box body 1 and reduce the non-battery core cost of the energy storage container 200.

[0080] In another example, the internal space of the box 1 can be divided by a partition net (net structure) or a partition frame (frame structure), for example, two partition nets arranged along the first direction are provided in the box 1, or two partition frames arranged along the first direction are provided in the box 1. As long as the internal space of the box 1 can be divided into the temperature control compartment 101, the battery compartment 102 and the power distribution compartment 103.

[0081] It should be noted that the temperature control compartment 101, the battery compartment 102 and the power distribution compartment 103 are not necessarily closed spaces, that is, the temperature control compartment 101, the battery compartment 102 and the power distribution compartment 103 can be interconnected. For example, one or more openings can be provided on the first partition 7 to connect the battery compartment 102 with the power distribution compartment 103. For another example, one or more openings can be provided on the second partition 8 to connect the temperature control compartment 101 with the battery compartment 102. In this way, it is convenient to connect the components in the three compartments (temperature control compartment 101, battery compartment 102 and power distribution compartment 103) by wiring or piping.

[0082] In addition, the temperature control compartment 101 and the power distribution compartment 103 are respectively located on both sides of the battery compartment 102, and the positions of the temperature control compartment 101 and the power distribution compartment 103 can be interchanged. For example, when facing the energy storage container 200 along the second direction, the temperature control compartment 101 can be located on the left side of the battery compartment 102, and the power distribution compartment 103 can be located on the right side of the battery compartment 102, or the power distribution compartment 103 can be located on the left side of the battery compartment 102, and the temperature control compartment 101 can be located on the right side of the battery compartment 102.

[0083] The size of the temperature control compartment 101 in the first direction, the size of the battery compartment 102 in the first direction, and the size of the power distribution compartment 103 in the first direction can all be set according to specific needs, and this application does not impose any restrictions on this.

[0084] In order to enable the energy storage container 200 to store and output electric energy, refer to Figure 3 and Figure 4 , Figure 4 The components inside the battery compartment 102 are shown as an example. The battery compartment 102 is provided with multiple columns of battery clusters 3 and a support frame 32. The multiple columns of battery clusters 3 are arranged on the support frame 32. Each column of battery clusters 3 ( Figure 4 The dashed box in the middle represents a battery cluster 3) including a plurality of battery packs 31 distributed along the height direction of the box body 1, for example, Figure 4 The figure shows a situation where five columns of battery clusters 3 are arranged in the battery compartment 102 .

[0085] The example battery pack 31 may be a lithium battery pack, and the battery pack 31 may include a housing and a plurality of battery cells, wherein the plurality of battery cells are installed in the housing. A battery pack 31 is provided in each layer of each column of battery clusters 3, and each battery pack 31 extends along the width direction of the box body 1, and the plurality of battery packs 31 are installed on a support frame 32. The example support frame 32 may be constructed as a mounting frame, a storage frame, a receiving frame, and the like, and the support frame 32 supports the battery pack 31.

[0086] In another example, the support frame 32 includes a plurality of storage cells distributed in a matrix, and each storage cell can accommodate a plurality of battery packs 31 arranged along the width direction of the box body 1 .

[0087] The support frame 32 is arranged in the box body 1. The width of the box body 1 can be about 2400 mm (for example, 2438 mm). In order to make full use of the internal space of the box body, refer to Figure 4, the size of the support frame 32 in the width direction of the box body 1 can be 1700mm to 2200mm, for example, the size of the support frame 32 in the width direction of the box body 1 can be 1700mm, 1800mm, 1900mm, 2000mm, 2100mm, 2200mm, etc. By making the size of the support frame 32 in the width direction of the box body 1 longer, the support frame 32 can accommodate longer (or more) battery packs 31, and the battery clusters 3 are distributed deeper in the width direction of the box body 1, so that the internal space of the box body 1 is better utilized, the number of battery cells in the battery compartment 102 is larger, and the energy density of the energy storage container 200 is improved.

[0088] If the temperature of the battery pack 31 is too high, the life of the battery pack 31 will be shortened and the risk of thermal runaway of the battery pack 31 will be increased. Figure 3 A liquid cooling unit 2 is provided in the temperature control compartment 101, and the liquid cooling unit 2 is used to cool the battery compartment 102 so that the battery cluster 3 can operate stably and normally.

[0089] Among them, refer to Figure 3 The liquid cooling unit 2 is connected with a liquid cooling pipe (not shown in the drawings), and the bottom of the second partition 8 is provided with a second opening (not shown in the drawings), which can be provided in the middle area of ​​the bottom of the second partition 8, and the liquid cooling pipe extends from the temperature control compartment 101 into the battery compartment 102 through the second opening. The liquid cooling unit 2 can transport the cooling medium (for example, refrigerant, cooling water, cooling oil, etc.) to the battery compartment 102 through the liquid cooling pipe, so that the cooling medium exchanges heat with the battery cluster 3 in the battery compartment 102, cools the battery cluster 3, and the cooling medium after heat exchange returns to the liquid cooling unit 2 through the liquid cooling pipe.

[0090] In some other examples, when the power distribution bin 103 needs to be cooled, the liquid cooling pipe can extend through the battery bin 102 into the power distribution bin 103, and the liquid cooling unit 2 can transport the cooling medium into the power distribution bin 103 through the liquid cooling pipe, so that the cooling medium exchanges heat in the power distribution bin 103, and the cooling medium after heat exchange returns to the liquid cooling unit 2 through the liquid cooling pipe.

[0091] In the example where liquid cooling pipes are inserted into both the battery compartment 102 and the power distribution compartment 103 , the battery compartment 102 and the power distribution compartment 103 are separated from each other and dissipate heat in a unified manner, so that the heat dissipation of the battery compartment 102 and the power distribution compartment 103 is taken into consideration while ensuring safe operation of the energy storage container 200 .

[0092] In addition, refer to Figure 3 The liquid cooling unit 2 and the battery cluster 3 are respectively arranged in two mutually separated chambers (temperature control chamber 101 and battery chamber 102), so that the liquid cooling unit 2 can operate better in an independent space, reducing the impact of the liquid cooling unit 2 on the battery cluster 3 during operation.

[0093] To operate with battery cluster 3, refer to Figure 5 , Figure 5 The structure in the power distribution warehouse 103 is shown as an example. The power distribution warehouse 103 is provided with a controller 4 for monitoring and controlling the multiple columns of battery clusters 3. The controller 4 can play at least one of the roles of overload protection, monitoring and control, load regulation, etc. The exemplary controller 4 can include a switch box, a circuit breaker, etc. In addition, the controller 4 can also be used to monitor the voltage, temperature and charge and discharge state of the battery pack 31, and can also adjust the charge and discharge cycle of the battery pack 31.

[0094] In order to protect the process of inputting and outputting electric energy of the battery cluster 3, refer to Figure 6 , Figure 6 The wiring between the battery cluster 3 and the controller 4 is shown as an example. The multiple battery clusters 3 are electrically connected to the controller 4 through multiple first power lines 41. The controller 4 is electrically connected to multiple second power lines 42 for current input or output. The box 1 is provided with a first wire port (attached) connected to the power distribution warehouse 103. Figure 6 The first wire passing opening is located at the bottom of the box body 1 , and a plurality of second power wires 42 extend out of the box body 1 through the first wire passing opening.

[0095] That is, when the energy storage container 200 is discharged, the current in the battery cluster 3 flows to the controller 4 through the first power line 41, and then is output to the outside through the second power line 42 on the controller 4. When the energy storage container 200 is charged, the external current flows to the controller 4 through the second power line 42, and then is input to the battery cluster 3 through the first power line 41.

[0096] Reference Figure 6 A first opening 71 is provided on the first partition 7 in the box body 1 for separating the battery compartment 102 and the power distribution compartment 103 , and a plurality of first power lines 41 extend from the battery compartment 102 into the power distribution compartment 103 through the first opening 71 .

[0097] There are many locations for the first opening 71. In one example, the first opening 71 is located at the bottom of the first partition 7, that is, the first power line 41 extends from the bottom of the battery compartment 102 into the power distribution compartment 103, so that the first power line 41 can share space with the pipeline at the bottom of the battery compartment 102 (for example, the liquid cooling pipe of the liquid cooling component extending into the battery compartment 102) or the wiring at the bottom of the battery compartment 102, thereby improving the space utilization rate at the bottom of the battery compartment 102, so that there is more space in the battery compartment 102 to arrange the battery cluster 3, and improving the energy density of the energy storage container 200. In another example, the first opening 71 can be set at the top of the first partition 7.

[0098] The first power line 41 extending from the battery compartment 102 into the power distribution compartment 103 may be wired in any suitable manner and connected to the controller 4. Figure 6The dotted line of the first power line 41 in the controller 4 only represents that the controller 4 blocks this part of the first power line 41, and does not represent that this part of the first power line 41 extends into the controller 4. The first power line 41 is connected to the connection terminal 44 of the controller 4 for connecting the power line.

[0099] The controller 4 may be any suitable device. In one example, Figure 5 and Figure 6 The controller 4 includes a plurality of battery cluster control boxes 43 arranged along the width direction of the box body 1, and the number of the battery cluster control boxes 43 is the same as the number of the plurality of battery clusters 3 (see Appendix Figure 4 5 rows of battery clusters 3 are shown in FIG. Figure 5 Five battery cluster control boxes 43 are shown in the figure, each battery cluster control box 43 corresponds to a column of battery clusters 3, so that each column of battery clusters 3 can be accurately monitored and controlled, and the controller 4 can control and adjust the corresponding battery cluster 3 through the corresponding battery cluster control box 43.

[0100] Reference Figure 5 and Figure 6 The multiple battery packs 31 in each column of battery clusters 3 are connected in series, and each column of battery clusters 3 is electrically connected to the corresponding battery cluster control box 43 through two first power lines 41. Each battery cluster control box 43 is provided with two terminals 44, which are respectively electrically connected to the two first power lines 41. Two second power lines 42 for outputting direct current are connected to the bottom of each battery cluster control box 43, and the multiple second power lines 42 at the bottom of the multiple battery cluster control boxes 43 extend out of the box body 1 through the first line port.

[0101] In this example, the power conversion system (PCS) is disposed outside the energy storage container 200 , and the battery cluster control box 43 needs to be externally connected to the power conversion system via the second power line 42 .

[0102] In another example, the controller 4 may include multiple energy storage inverters arranged along the width direction of the box 1, the number of the energy storage inverters is the same as the number of columns of battery clusters 3, multiple battery packs 31 in each column of battery clusters 3 are connected in series, and each column of battery clusters 3 is electrically connected to the corresponding energy storage inverter through two first power lines 41. The bottom of each energy storage inverter is connected to multiple second power lines 42 serving as AC lines.

[0103] The energy storage converter is composed of a DC / AC bidirectional converter, a control unit, etc., and can control the charging and discharging of the battery cluster 3, perform AC and DC conversion, etc. Each energy storage converter corresponds to a column of battery clusters 3, so that each column of battery clusters 3 can be accurately monitored and controlled. In addition, when the energy storage container 200 is discharged, AC power is directly output from the energy storage converter, without the need to convert the current output from the second power line 42.

[0104] In some other examples, the controller 4 may include a plurality of DC-DC converters arranged along the width direction of the box body 1, so that the energy storage container 200 can increase or decrease the output voltage according to demand.

[0105] Reference Figure 5 , an auxiliary power distribution cabinet 5 is also provided in the power distribution warehouse 103, and the auxiliary power distribution cabinet 5 supplies power to the liquid cooling unit or other components in the energy storage container 200. The auxiliary power distribution cabinet 5 and the controller 4 are arranged along the width direction of the box body 1, that is, the auxiliary power distribution cabinet 5 is located on one side of the controller 4. The terminal block 51 on the auxiliary power distribution cabinet 5 is electrically connected with a third power line (not shown in the drawings) for connecting to an external power source, and the box body 1 is provided with a second line port (not shown in the drawings) connected to the power distribution warehouse 103, and the third power line extends out of the box body 1 through the second line port. The circuit of the external power supply is transmitted to the auxiliary power distribution cabinet 5 through the third power line, and then transmitted to the equipment that needs power supply through the auxiliary power distribution cabinet 5. For example, the auxiliary power distribution cabinet 5 and the equipment that needs power supply are electrically connected through the distribution line.

[0106] The first wire opening and the second wire opening can be arranged at any suitable position, for example, Figure 5 The first and second wire-passing openings are arranged at the bottom of the box 1, which reduces the possibility of foreign matter entering the power distribution warehouse 103 and protects the components in the power distribution warehouse 103. In addition, the second power line 42 and the third power line extend from the bottom of the box 1, so that the first power line 41 and the second power line 42 extending out of the box 1 are close to the ground, which is convenient for arranging and fixing the cables extending out of the energy storage container 200. For another example, the first and second wire-passing openings can be arranged on the side walls of the box 1, as long as the cables in the power distribution warehouse 103 can be extended.

[0107] The first wire passing opening may include a plurality of independent small holes, each small hole for a second power wire 42 to pass through, or the first wire passing opening may be a large hole, through which a plurality of second power wires 42 extend out of the box body 1, and the present application does not impose any specific limitation on this.

[0108] Similarly, the second wire passing opening may include multiple independent small holes, each small hole for a third power line (due to the external alternating current, multiple third power lines are required) to pass through, and the second wire passing opening may also be a large hole, and multiple third power lines all extend out of the box body 1 through the large hole. The present application does not impose specific restrictions on this.

[0109] In addition, the auxiliary power distribution cabinet 5 can also serve as the "brain" of the entire energy storage container 200. The auxiliary power distribution cabinet 5 is connected to the controller 4, the liquid cooling unit 2 and other components through multiple signal lines to monitor and control the operation of the energy storage container 200. The auxiliary power distribution cabinet 5 can also be connected to multiple signal lines extending outside the box body 1 to electrically connect to the control mechanism of the power station.

[0110] The controller 4 is also connected to signal lines that need to be connected to the outside. For example, in the example where the controller 4 includes multiple battery cluster control boxes 43, the battery cluster control box 43 is connected to multiple signal lines that need to extend outside the box 1. These signal lines will be electrically connected to the external energy storage inverter.

[0111] In order to facilitate external connection of the energy storage container 200 (for example, the external second power line 42, the third power line, some signal lines, etc.), the cables that need to be extended are concentrated in the power distribution warehouse 103 and then extended from the power distribution warehouse 103. Since the power distribution warehouse 103 is located on one side of the box body 1, it is convenient for wiring, and the wiring space and outlet space of the box body 1 are large, so it is easy to realize external connection of the energy storage container 200.

[0112] The power distribution compartment 103 has a large space, and the controller 4 and the auxiliary power distribution cabinet 5 are arranged in the power distribution compartment 103, which is convenient for placing the controller 4 and the auxiliary power distribution cabinet 5. The power distribution and control equipment such as the controller 4 and the battery cluster 3 are respectively located in two mutually separated compartments, which reduces safety hazards and makes the energy storage container 200 more stable and safe during operation.

[0113] In addition, the controller 4 and the auxiliary power distribution cabinet 5 are independently arranged in the power distribution compartment 103, so that the battery compartment 102 can have a larger area to install the battery cluster 3, and the size of the battery pack 31 in the height direction can be increased. For example, the size of the battery pack 31 in the height direction can be 240 mm to 290 mm, wherein the size of the battery pack 31 in the height direction can be 240 mm, 250 mm, 275 mm, 283 mm, 290 mm, etc. A single battery pack 31 can accommodate more cells, reduce the number of battery packs 31, reduce the manufacturing cost, and improve the energy density of the energy storage container 200.

[0114] The controller 4 does not occupy the internal space of the battery compartment 102, so that more area in the battery compartment 102 can be used to install other equipment that assists the operation of the battery cluster 3, making the system evolution of the energy storage container 200 of the present application better.

[0115] In order to deal with the situation of internal combustion of the energy storage container 200, refer to Figure 5 and Figure 6A fire extinguisher 61 and a fire host 62 for controlling the fire extinguisher 61 are arranged in the power distribution compartment 103. A fire hose 611 is connected to the fire extinguisher 61. A second opening 72 is arranged on the top of the first partition 7. The fire hose 611 extends into the battery compartment 102 through the second opening 72 and is located above the multiple columns of battery clusters 3. A plurality of nozzles 6111 located in the battery compartment 102 are arranged on the wall of the fire hose 611.

[0116] The auxiliary power distribution cabinet 5 can supply power to the fire extinguisher 61 and the fire host 62, and the fire host 62 controls the fire extinguisher 61 to output the fire extinguishing agent. When a fire occurs in the battery compartment 102 (for example, the battery pack 31 ignites and explodes due to thermal runaway), the fire extinguishing agent in the fire extinguisher 61 flows into the battery compartment 102 through the fire hose 611 and is ejected from the nozzle 6111 on the fire hose 611. The ejected fire extinguishing agent falls from above the battery cluster 3 to extinguish the fire in the battery compartment 102, thereby reducing the possibility of further spread of the flame in the battery compartment 102 and reducing the risk of explosion of the energy storage container 200.

[0117] The fire extinguisher 61 and the fire main unit 62 can be arranged at any suitable position. For example, a strong current area and a weak current area can be divided in the power distribution warehouse 103. The input and output in the first power line 41 and the second power line 42 are strong current, and the auxiliary power distribution cabinet 5, the fire extinguisher 61 and the fire main unit are weak current equipment. The fire extinguisher 61 and the fire main unit 62 are arranged above the auxiliary power distribution cabinet 5, so that the auxiliary power distribution cabinet 5, the fire extinguisher 61 and the fire main unit 62 are separated from the controller 4, reducing the possibility of strong current interfering with weak current in the power distribution warehouse 103. In addition, there may be a high risk of electric shock and fire in the strong current line. Separating the strong current and the weak current can reduce the occurrence of such risks and facilitate safe and compliant wiring in the power distribution warehouse 103.

[0118] In order to protect the components inside the box 1, the box 1 may include a frame 18, a box board, a box door and other structures. Figure 2 The frame 18 of the box body 1 can be formed by 12 connecting beams, and the frame 18 is the skeleton of the box body 1. The box body 1 can also include a first side wall 11 and a second side wall 12 (distributed along its length direction) Figure 2 The first side wall 11 in the box body 1 refers to the side wall opposite to the second side wall 12, which can be used as an auxiliary reference. Figure 4 ). Combined Figure 4 and Figure 5 The box body 1 may further include a third side wall 13 and a fourth side wall 14 arranged along the width direction of the box body 1.

[0119] The power distribution compartment 103 is formed between the first side wall 11 and the first partition 7 , and the temperature control compartment 101 is formed between the second side wall 12 and the second partition 8 .

[0120] In addition, refer to Figure 6 The box body 1 may further include a top wall 15 and a bottom wall 16 arranged in the vertical direction, with a certain distance between the top wall 15 and the bottom wall 16. The top wall 15 and the bottom wall 16 may be the top plate and the bottom plate of the box body 1 respectively, and both are mounted on the frame 18. The top wall 15, the bottom wall 16, the first side wall 11, the second side wall 12, the third side wall 13 and the fourth side wall 14 together enclose the internal space of the box body 1, which protects the components in the box body 1 and prevents the external environment from affecting the components in the box body 1.

[0121] In the above, the “wall” in the first side wall 11 , the second side wall 12 , the third side wall 13 , the fourth side wall 14 , the top wall 15 and the bottom wall 16 refers to a wall structure having thickness, which may be a box board, a box door or the like.

[0122] In an example, the first side wall 11 , the second side wall 12 , the third side wall 13 and the fourth side wall 14 may all be box panels (eg, corrugated panels), and the four box panels may all be mounted on the frame 18 .

[0123] In another example, referring to Figure 5 In order to facilitate the staff to inspect the components in the power distribution warehouse 103, the first side wall 11 may include a first door body 111 (for example, two first door bodies 111), Figure 5 1 shows the case where the first door body 111 is a transparent door. The first door body 111 is used to open or close the power distribution compartment 103, so that the staff can work in the power distribution compartment 103 more conveniently.

[0124] In the example where the first side wall 11 includes the first door body 111, the controller 4, the auxiliary distribution cabinet 5, the fire extinguisher 61 and the fire host 62 may be all fixed on the first partition 7; alternatively, the controller 4, the auxiliary distribution cabinet 5 and the fire extinguisher 61 may be fixed on the first partition 7, and the fire host 62 may be fixed on the first door body 111. In order to distinguish between the strength area and the weakness area, the fire host 62 may be positioned on the first door body 111 close to the auxiliary distribution cabinet 5 and away from the controller 4.

[0125] In another example, in order to facilitate installation and maintenance of the battery cluster 3, refer to Figure 4 At least one of the third side wall 13 and the fourth side wall 14 includes a second door 131, and the second door 131 is used to open or close the battery compartment 102. When the battery cluster 3 needs to be installed, replaced or repaired, the second door 131 can be opened to perform the corresponding operation. When the battery cluster 3 is running, closing the second door 131 can protect the battery cluster 3 and reduce the possibility of the external environment interfering with the normal operation of the battery cluster 3.

[0126] In some examples, the second door body 131 may be a transparent door body so as to observe the internal situation of the box body 1. In other examples, the second door body 131 may also be an opaque door body. The second door body 131 may be produced in any suitable form, and the present application does not specifically limit the structure and quantity of the second door body 131.

[0127] In some examples, the energy storage container 200 is an energy storage container 200 with doors opened on both sides, that is, the third side wall 13 and the fourth side wall 14 of the container body 1 both include a second door body 131 .

[0128] In other examples, the energy storage container 200 has a single-side door, for example, Figure 4 and Figure 5 The third side wall 13 of the box body 1 may include multiple second door bodies 131 and two mounting plates 132. The multiple second door bodies 131 are distributed along the length direction of the box body 1. The multiple second door bodies 131 are located between the two mounting plates 132 in the length direction of the box body 1. The multiple second door bodies 131 are located between the first partition plate 7 and the second partition plate 8.

[0129] Reference Figure 7 , Figure 7 The following is an exemplary diagram showing the distribution of multiple energy storage containers 200 after being combined (from a top view). In the example of an energy storage container 200 with a door opened on one side, two adjacent energy storage containers 200 can be combined in a "back-to-back" manner, that is, when two energy storage containers 200 are combined along the width direction (second direction) of the container body 1, the third side walls 13 of the two energy storage containers 200 are separated from each other, and the fourth side walls 14 of the two energy storage containers 200 are arranged opposite to each other. There is no need to open a door on one side of the fourth side wall 14, and the distance between the two "back-to-back" energy storage containers 200 ( Figure 7 The spacing L1) in the box can be very small, for example, L1 can be less than 600mm, so as to realize short-distance box connection.

[0130] After two adjacent energy storage containers 200 are placed "back to back", in order to prevent the combustion of one of the energy storage containers 200 from affecting the other energy storage container 200, the fourth side wall 14 may include a first box board (not shown in the drawings) and a first fireproof board (not shown in the drawings). The first fireproof board is connected to the wall of the first box board facing the internal space of the box body 1, that is, the first fireproof board is located on the inner side of the first box board. The first fireproof board can reduce the impact of external flames on the energy storage container 200.

[0131] Among them, the first fireproof board can be a fire-resistant building material board, or it can be other boards with fire-resistant (or fire-proof) functions, and this application does not make specific restrictions on this.

[0132] On the basis of the above scheme, when one energy storage container 200 burns, the probability that another energy storage container 200 arranged “back to back” with the burning energy storage container 200 is also ignited is small, and the safety distance between the two energy storage containers 200 placed “back to back” can be shortened, and the distance between the two adjacent energy storage containers 200 in the second direction after the boxes are combined is further reduced, and the floor space of multiple energy storage containers 200 is reduced, so that the energy density of the energy storage container system 100 is higher.

[0133] Reference Figure 7 Two adjacent energy storage containers 200 may also be placed side by side in a “shoulder to shoulder” manner, that is, the two energy storage containers 200 are placed side by side along the length direction (first direction) of the container body 1, and the first side walls 11 of the two energy storage containers 200 are arranged opposite to each other.

[0134] After two adjacent energy storage containers 200 are placed "shoulder to shoulder", in order to prevent one of the energy storage containers 200 from burning and affecting the other energy storage container 200, in other examples, the first side wall 11 may include a second box board (not shown in the drawings) and a second fireproof board (not shown in the drawings). The second fireproof board is located on the inner side of the first box board (the side close to the inner space of the box body 1).

[0135] Among them, the second fireproof board can be a fire-resistant building material board, or it can be other boards with fire-resistant (or fire-proof) functions, and this application does not make specific restrictions on this.

[0136] On the basis of the above solution, when one energy storage container 200 burns, the other energy storage container 200 placed "side by side" with the burning energy storage container 200 is difficult to be ignited under the protection of the second fireproof board. The second fireproof board can reduce the impact of external flames on the energy storage container 200, making the safety distance between the two energy storage containers 200 placed "side by side" smaller, and further reducing the distance between the two adjacent energy storage containers 200 in the first direction after the boxes are combined ( Figure 6 For example, L2 may be less than 1500 mm, thereby reducing the footprint of multiple energy storage containers 200 and further increasing the energy density of the energy storage container system 100.

[0137] In addition, the liquid cooling unit 2 needs to exchange heat with the outside during operation. Figure 2The side wall of the box 1 and the top of the box 1 are both provided with air vents (air inlet 121 and air outlet 151) connected to the temperature control chamber 101. The liquid cooling unit 2 includes a heat exchange fan (not shown in the drawings). Under the operation of the heat exchange fan, the outside air enters the temperature control chamber 101 from the air vents, completes heat exchange with the liquid cooling unit 2, and is then discharged from the air vents. The temperature control chamber 101 is located on one side of the box 1, so that the liquid cooling unit 2 can inhale more surrounding air, which is beneficial to the operation of the liquid cooling unit 2 and improves the temperature control efficiency.

[0138] The air inlet 121 can be arranged on the side wall of the box body 1, for example, the first side wall 11, the third side wall 13 and the fourth side wall 14 are respectively provided with a plurality of air inlets 121. The heat exchange fan is located at the top of the temperature control chamber 101, the air inlet end of the heat exchange fan faces downward, and the plurality of air inlets 121 on the first side wall 11, the third side wall 13 and the fourth side wall 14 can all be located below the heat exchange fan so that the heat exchange fan can absorb air.

[0139] The air outlet 151 can be provided with multiple and located on the top wall 15 of the box body 1, and the air outlet end of the heat exchange fan faces upward, so that the air can be discharged from the air outlet. The air inlet 121, the temperature control chamber 101 and the air outlet 151 form an air passage for the heat exchange fan to absorb and exhaust air.

[0140] Air inlets 121 are provided on multiple sides of the temperature control chamber 101, so that more air around the box body 1 can be sucked into the temperature control chamber 101. The more gas sucked into the temperature control chamber 101, the better the heat exchange effect of the liquid cooling unit 2. The gas after heat exchange is then discharged from the air outlet 151 of the top wall 15, further improving the temperature control efficiency of the liquid cooling unit 2, and can more effectively cool the battery cluster 3.

[0141] In other examples, one or both of the first side wall 11 , the third side wall 13 and the fourth side wall 14 are provided with an air inlet 121 .
