[0074] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0076] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0077] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0078] With the continuous development of new energy technologies, various technologies related to energy storage are also constantly upgraded; among them, energy storage containers that use containers as energy storage methods have been widely used. Energy storage containers include a box body and energy storage modules (such as battery clusters, batteries, battery cells, etc.) contained in the box body, liquid cooling equipment, fire fighting equipment, power distribution modules, signal and power supply module boxes and other module equipment. Considering the transportation of energy storage containers, the box body generally adopts standard-sized containers. Therefore, standard-sized energy storage containers are subject to size restrictions. How to reasonably layout the space inside the energy storage container is particularly critical.

[0079] In the related art, the space in the box for accommodating energy storage modules and the space for accommodating other modules are generally cross-divided; for example, liquid cooling equipment and fire-fighting equipment are integrated in the space for accommodating energy storage modules. Since various module equipment are integrated in the same space, the arrangement of lines, pipelines, etc. in the same space will affect the use of the space. Therefore, the space utilization rate in the box is low at this time, which will also affect the energy storage density, and is also not conducive to the separate maintenance of various module equipment; or, liquid cooling equipment, fire-fighting equipment and other various module equipment are respectively located at the opposite ends of the space for accommodating energy storage units. At this time, when there are multiple energy storage containers, multiple energy storage containers cannot be arranged adjacent to each other, otherwise it will affect the maintenance of various module equipment. Therefore, the multiple energy storage containers occupy a larger area and the energy storage density per unit area will also be reduced.

[0080] Based on the above considerations, in order to solve the problem of the rationality of the internal layout of the energy storage container, an energy storage container is designed. By arranging the electrical compartment and the liquid cooling unit on the same side of the battery compartment along the first direction, that is, the electrical compartment and the liquid cooling unit are separated from the battery compartment and independently arranged, the space utilization rate of the container can be effectively improved, and when multiple energy storage containers are arranged, the battery compartment sides of two adjacent energy storage containers can be placed against each other, which can reduce the space occupied by the arrangement of multiple energy storage containers to increase the energy storage density per unit area.

[0081] Please refer to Figure 1 , Figure 2 and Figure 5 In the first aspect, an embodiment of the present application provides an energy storage container 100, including a box body 10, wherein a battery compartment 20, an electrical compartment 30 and a liquid cooling unit 40 are arranged inside the box body 10; the electrical compartment 30 and the liquid cooling unit 40 are arranged on the same end side of the battery compartment 20 in the first direction O.

[0082] The box body 10 is the container body structure of the energy storage container 100 , and the box body 10 is a standard-sized container. A cavity is formed inside the box body 10 for arranging other module equipment such as the battery compartment 20 , the electrical compartment 30 , and the liquid cooling unit 40 in the box body 10 .

[0083] It should be understood that the box body 10 as a container can be a rectangular parallelepiped structure. For the convenience of description, the embodiment of the present application defines three directions based on the rectangular parallelepiped container, wherein the length direction of the box body 10 can be defined as the first direction O, the width direction of the box body 10 can be defined as the second direction P, and the height direction of the box body 10 can be defined as the third direction Q. Therefore, in the embodiment of the present application, the electrical compartment 30 and the liquid cooling unit 40 are arranged on the same side of the battery compartment 20 in the first direction O, that is, the electrical compartment 30 and the liquid cooling unit 40 can be arranged on the same side of the battery compartment 20 in the length direction of the box body 10.

[0084] The battery compartment 20 is used to accommodate energy storage modules, such as battery cells, or batteries formed by battery cells, or battery clusters formed by batteries connected in series, etc. Taking a battery cluster as an example, the battery compartment 20 can accommodate one or more battery clusters. In the case of multiple battery clusters, the battery clusters are arranged along a first direction O in the battery compartment 20.

[0085] Optionally, the battery compartment 20 can be formed by constructing partitions, mounting beams, brackets and other structures in the box body 10, and the battery compartment 20 as an independent space can be built using partitions, mounting beams, brackets and other structures to provide for the arrangement of battery clusters, etc.

[0086] The electrical compartment 30 is used to accommodate electrical equipment. For example, the electrical compartment 30 can accommodate, including but not limited to, a distribution box, a main control box, a fire control module, fire pipes, fans, etc.; optionally, the electrical compartment 30 can be formed by erecting structures such as partitions, mounting beams, and brackets in the box body 10, and the electrical compartment 30 as an independent space can be built using partitions, mounting beams, brackets, and other structures to provide for the arrangement of electrical equipment, etc.

[0087] The liquid cooling unit 40 is a cooling device for providing circulating coolant to the battery compartment 20; the liquid cooling unit 40 can be directly accommodated inside the box 10 and arranged adjacent to the battery compartment 20; or, a liquid cooling compartment in an independent space can be built in the box 10 using partitions, mounting beams, brackets and other structures to accommodate the liquid cooling unit 40. The liquid cooling unit 40 can be a unit using cooling water, cooling oil, refrigerant and other cooling media; optionally, the liquid cooling unit 40 can be a water cooling unit for cooling using cooling water.

[0088] Among them, the electrical compartment 30 and the liquid cooling unit 40 are arranged on the same end side of the battery compartment 20 in the first direction O. Optionally, the compartment door of the electrical compartment 30 and the operating end surface of the liquid cooling unit 40 can be located at the end of the box body 10 and exposed to the box body 10. Thus, the operator can operate and maintain the electrical compartment 30 and the liquid cooling unit 40 on the same side outside the box body 10.

[0089] The energy storage container 100 provided in the embodiment of the present application can effectively improve the space utilization rate of the container by arranging the electrical compartment 30 and the liquid cooling unit 40 on the same end side of the battery compartment 20 in the first direction O; at the same time, the staff can check the electrical compartment 30 and the liquid cooling unit 40 on the same end side of the energy storage container 100, which effectively improves the convenience of on-site maintenance; and when installing and configuring the energy storage container 100, the layout mode in which the electrical compartment 30 and the liquid cooling unit 40 are located on the same side can also improve the convenience of assembly. When arranging multiple energy storage containers 100, the battery compartment 20 sides of two adjacent energy storage containers 100 can also be placed against each other, which can reduce the space occupied by the arrangement of multiple energy storage containers 100 to improve the energy storage density per unit area; therefore, in the energy storage container 100 provided in the embodiment of the present application, the layout mode in which the electrical compartment 30 and the liquid cooling unit 40 are located on the same side of the battery compartment 20 is more reasonable.

[0090] Please refer to Figure 1 , Figure 2 and Figure 5 In some embodiments, the electrical compartment 30 and the liquid cooling unit 40 are arranged along a second direction P, and the second direction P is perpendicular to the first direction O.

[0091] It can be understood that the first direction O can be the length direction of the box body 10 , and thus the second direction P can be the width direction of the box body 10 .

[0092] The electrical compartment 30 and the liquid cooling unit 40 are located on the same side of the battery compartment 20 in the first direction O, that is, one end side of the electrical compartment 30 and the liquid cooling unit 40 in the length direction of the box body 10 .

[0093] On this basis, the electrical compartment 30 and the liquid cooling unit 40 are also arranged in the second direction P, that is, the electrical compartment 30 and the liquid cooling unit 40 are arranged in the width direction of the box 10, so that the electrical compartment 30 and the liquid cooling unit 40 are located at one end side in the length direction of the box 10, and the electrical compartment 30 and the liquid cooling unit 40 are arranged in sequence at the end side of the box 10 and along the width direction of the box 10. Therefore, the staff can perform maintenance and repair on the electrical compartment 30 and the liquid cooling unit 40 at the end of the box 10 at the same time, which effectively improves the convenience of maintenance.

[0094] Optionally, the electrical compartment 30 is formed with a compartment door in the first direction O and on the outer side of the box body 10. The control buttons, display panel, etc. of the fire control module or other modules can be installed on the compartment door of the electrical compartment 30 to make full use of the space in the electrical compartment 30, improve the space utilization rate of the electrical compartment 30, and thereby reduce the proportion of the entire electrical compartment 30 in the box body 10, so that the battery compartment 20 can account for a larger proportion of the box body 10, so as to achieve the purpose of increasing the energy storage density.

[0095] Please refer to Figures 3 to 5 In some embodiments, a battery cluster 50 and a main control box 60 are further included. The battery cluster 50 is arranged in the battery compartment 20 along the first direction O. The main control box 60 is provided on one side of the battery cluster 50 in the third direction Q. The battery cluster 50 is electrically connected to the main control box 60. The first direction O, the second direction P and the third direction Q are all perpendicular to each other.

[0096] The battery cluster 50 refers to a battery system formed by combining multiple batteries or battery cells into a group to work together under certain conditions. The battery cluster 50 can improve the reliability, stability and life of the entire system through the cooperation between batteries or battery cells. Compared with the non-cluster design, the design of the battery cluster 50 can improve the system consistency and reduce the connection structure between battery cells, thereby increasing the overall discharge capacity.

[0097] The number of battery clusters 50 may be one or more than one. When there are multiple battery clusters 50 , the multiple battery clusters 50 may be sequentially arranged in the battery compartment 20 along the first direction O, that is, the length direction of the box 10 .

[0098] The main control box 60 is used to be electrically connected to the battery cluster 50, for example, by networking the battery cluster 50 through CAN (Controller Area Network) communication, so as to realize electrical control of the battery cluster 50. Each battery cluster 50 is provided with a main control box 60 on one side in the third direction Q, that is, each battery cluster 50 is provided with a main control box 60 to control it individually, so as to improve controllability.

[0099] The main control box 60 is arranged on one side of the battery cluster 50 along the third direction Q. It can be understood that the third direction Q can be the height direction of the box 10. Therefore, the main control box 60 can be arranged above or below the corresponding battery cluster 50 in the height direction of the box 10 to reasonably utilize the space in the battery compartment 20 and reduce the influence on the arrangement of the battery cluster 50 along the first direction O. Optionally, the main control box 60 can be arranged below the battery cluster 50 in the height direction of the box 10, so that the installation position of the main control box 60 is lower, which can facilitate its maintenance.

[0100] In this way, by setting up the battery cluster 50, the internal connection structure can be reduced and the system consistency can be improved; at the same time, the main control box 60 is set on the side of the third direction Q of the battery cluster 50, which rationally utilizes the space in the battery compartment 20 and improves the space utilization and maintainability of the battery compartment 20.

[0101] Please refer to Figures 3 to 6 In some embodiments, the battery cluster 50 includes at least two electrically connected batteries 51 , and the multiple batteries 51 of the battery cluster 50 are arranged in sequence along the third direction Q.

[0102] Among them, the battery 51 is used to store energy and electric energy; the battery 51 mentioned in the present application may include a battery module or a battery pack, etc. For example, taking the battery 51 including a battery pack as an example, the battery 51 includes a battery box 510 and a battery cell 520, and the battery cell 520 is accommodated in the battery box 510. Among them, the battery box 510 is used to provide a storage space for the battery cell 520, and the battery box 510 can adopt a variety of structures. In some embodiments, the battery box 510 may include a first part 511 and a second part 512, the first part 511 and the second part 512 cover each other, and the first part 511 and the second part 512 jointly define a storage space for accommodating the battery cell 520. The battery box 510 formed by the first part 511 and the second part 512 can be in a variety of shapes, such as a cylinder, a cuboid, etc.

[0103] The multiple batteries 51 in the battery cluster 50 may be connected in series, or in parallel, or the multiple batteries 51 may be connected in a combination of series connection and parallel connection.

[0104] The battery cluster 50 includes at least two batteries 51, so that at least two batteries 51 can be arranged in sequence in the third direction Q, that is, the batteries 51 are arranged in sequence in the height direction of the box 10. Optionally, a support frame can be set in the battery compartment 20, so that the battery 51 can be supported and placed on the support frame; for example, when the battery 51 cluster 50 includes 8 batteries 51, 8 support frames are installed in the battery compartment 20 at intervals along the height direction of the box 10, and each battery 51 is respectively assembled on a corresponding support frame; when the number of battery clusters 50 is 4 clusters, the support frames are arranged in 4 longitudinal columns at intervals along the length direction of the box 10, and each longitudinal column includes 8 support frames arranged at intervals along the height direction, so that each longitudinal column of support frames is used to assemble 8 batteries 51 in a cluster of battery clusters 50, and 4 longitudinal columns of support frames can assemble batteries 51 in 4 clusters of battery clusters 50.

[0105] In some embodiments, the main control box 60 corresponding to each battery cluster 50 is respectively arranged at one end of the battery cluster 50 along the third direction Q, that is, the main control box 60 and the multiple batteries 51 are arranged in the third direction Q, and the main control box 60 is located at one end of the multiple batteries 51 in the third direction Q. Optionally, the main control box 60 can be located at the bottom of the multiple batteries 51 in the height direction of the box body 10.

[0106] In this way, at least two batteries 51 in the battery cluster 50 can be arranged in sequence along the third direction Q. Therefore, when multiple battery clusters 50 are arranged along the first direction O, the arrangement of the batteries 51 reasonably utilizes the space in the battery compartment 20, which can improve the space utilization rate in the battery compartment 20, and further improve the energy storage density of the energy storage container 100.

In this way, when the batteries 51 are arranged in four vertical columns and eight horizontal columns, the space utilization in the battery compartment 20 is better, and thus the energy storage density of the energy storage container 100 is also relatively better.

[0125] It can be understood that the batteries 51 in the battery cluster 50 are arranged along the third direction Q, and thus, the product of the number B of the batteries 51 in each battery cluster 50 and the height Z of the batteries 51 along the third direction Q is the sum of the heights of the batteries 51 arranged in the third direction Q. The number B of the batteries 51 in each battery cluster 50 is a positive integer, such as 1, 2, 3, 4, 5, etc.

[0126] The ratio of the sum of the heights BZ of the batteries 51 arranged in the third direction Q to the height N of the battery compartment 20 along the third direction Q is the ratio of the sum of the heights BZ of the batteries 51 arranged in the third direction Q to the height of the battery compartment 20 along the third direction Q.

[0128] In this way, the ratio of the sum of the heights BY of the batteries 51 arranged along the third direction Q to the height N of the battery compartment 20 in the third direction Q is set to be greater than or equal to 0.55 and less than or equal to 0.9, so that the sum of the heights of the batteries 51 arranged in the third direction Q has a sufficient proportion compared to the height of the battery compartment 20, so as to improve the energy density of the energy storage container 100.

[0129] Please refer to Figures 3 to 5 , in some embodiments, 0.75≤(BZ) / N≤0.85.

[0130] Optionally, the sum of the heights of the batteries 51 arranged in the third direction Q accounts for a ratio (BZ) / N of the height of the battery compartment 20 along the third direction Q, which can be selected as 0.75, 0.76, 0.77, 0.78, 0.79, 0.80, 0.81, 0.82, 0.83, 0.84, 0.85, etc.

[0132] Please refer to Figure 1 , Figure 3 and Figure 4 In some embodiments, the length of the box body 10 along the first direction O is H, and the length of the battery compartment 20 along the first direction O is L, wherein 0.6≤L / H≤0.95.

[0133] It can be understood that the ratio of the length L of the battery compartment 20 along the first direction O to the length H of the housing 10 along the first direction O is the proportion of the battery compartment 20 to the housing 10 in the first direction O.

[0135] In this way, the ratio of the length L of the battery compartment 20 along the first direction O to the length H of the box body 10 in the first direction O is set to be greater than or equal to 0.6 and less than or equal to 0.95, so that the battery compartment 20 has a sufficient proportion compared to the box body 10, so that the battery compartment 20 has sufficient space to accommodate the battery 51, thereby improving the energy density of the energy storage container 100.

[0136] Please refer to Figure 1 , Figure 3 and Figure 4 , in some embodiments, 0.75≤L / H≤0.9.

[0137] Optionally, the battery compartment 20 accounts for a specific gravity L / H of the box body 10 in the first direction O, which can be 0.75, 0.76, 0.77, 0.78, 0.79, 0.80, 0.81, 0.82, 0.83, 0.84, 0.85, 0.86, 0.87, 0.88, 0.89, 0.90, etc.

[0138] It can be understood that in order to further optimize the proportion of the battery compartment 20 in the first direction O to the box body 10, the ratio of the length L of the battery compartment 20 along the first direction O to the length H of the box body 10 in the first direction O can be further limited to be greater than or equal to 0.75 and less than or equal to 0.9, so as to further optimize the space occupied by the battery compartment 20 in the box body 10, so as to further optimize the capacity of the battery compartment 20 for the battery 51, thereby optimizing the energy density of the energy storage container 100.

[0140] It can be understood that the ratio of the length D of the electrical compartment 30 along the first direction O to the length H of the box body 10 along the first direction O is the weight of the electrical compartment 30 to the box body 10 in the first direction O. The liquid cooling unit 40 and the electrical compartment 30 are arranged in the second direction P, so the weight of the electrical compartment 30 to the box body 10 in the first direction O can be considered as the weight of the liquid cooling unit 40 and the electrical compartment 30 together to the box body 10 in the first direction O.

[0143] Please refer to Figure 1 , Figure 3 and Figure 4 , in some embodiments, 0.1≤D / H≤0.2.

[0144] Optionally, the proportion D / H of the electrical warehouse 30 to the box body 10 in the first direction O can be 0.10, 0.11, 0.12, 0.13, 0.14, 0.15, 0.16, 0.17, 0.18, 0.19, 0.20, etc.

[0145] It can be understood that in order to further optimize the proportion of the electrical compartment 30 in the first direction O to the box body 10, the ratio of the length D of the electrical compartment 30 along the first direction O to the length H of the box body 10 in the first direction O can be further limited to be greater than or equal to 0.1 and less than or equal to 0.2, thereby further optimizing the space occupied by the electrical compartment 30 in the box body 10, so as to further reduce the impact of the electrical compartment 30 on the space of the battery compartment 20, thereby optimizing the energy density of the energy storage container 100.

[0146] Please refer to Figure 3 , Figure 4 , Figure 6 and Figure 7 In some embodiments, the battery 51 includes a battery cell 520, and the battery cell 520 at least satisfies:

[0147] The length of the battery cell 520 along the first direction is E, and the number of the battery cells 520 arranged in the battery compartment 20 along the first direction O is I, wherein E≥240 mm (millimeter, hereinafter replaced by mm), 16≤I≤22; the length of the battery compartment 20 along the first direction O is L, 0.55≤(EI) / L≤0.95;

[0148] And / or, the width of the battery cell 520 along the second direction P is F, the number of battery cells 520 arranged along the second direction P in the battery compartment 20 is J, F ≥ 60 mm, 26 ≤ J ≤ 35; the width of the battery compartment 20 along the second direction P is M, 0.55 ≤ (FJ) / M ≤ 0.95;

[0149] And / or, the height of the battery cell 520 along the third direction Q is G, the number of battery cells 520 arranged along the third direction Q in the battery compartment 20 is K, G≥180mm, 6≤K≤9; the height of the battery compartment 20 along the third direction Q is N, 0.55≤(GK) / N≤0.95.

[0150] It can be understood that in order to optimize the energy density in the box body 10, the length E of the battery cell in the battery 51 along the first direction O, and / or the width F in the second direction P, and / or the height G in the third direction Q can be limited; for example, the length E of the battery cell 520 along the first direction O is limited to E≥240mm, and the number of battery cells 520 arranged along the first direction O in the battery compartment 20 is between 16 and 22; and / or, the width of the battery cell 520 along the second direction P is limited to F≥60mm, and the number of battery cells 520 arranged along the second direction P in the battery compartment 20 is between 26 and 35; and / or, the height of the battery cell 520 along the third direction Q is limited to G≥180mm, and the number of battery cells 520 arranged along the third direction Q in the battery compartment 20 is between 6 and 9.

[0151] In addition, the proportion of the battery cells 520 arranged in the first direction O, the second direction P and the third direction Q to the battery compartment 20 in the first direction O, the second direction P and the third direction Q is limited. For example, in the first direction O, it is limited to 0.55≤(EI) / L≤0.95, in the second direction P, it is limited to 0.55≤(FJ) / M≤0.95, and in the third direction Q, it is limited to 0.55≤(GK) / N≤0.95.

[0152] Such a configuration can improve the energy density in the battery compartment 20 by limiting the external dimensions of the battery cells 520 and the number of battery cells 520 arranged in the first direction O, the second direction P and / or the third direction Q.

[0153] Please refer to Figure 3 , Figure 4 , Figure 6 and Figure 7 , in some embodiments, 0.75≤(EI) / L≤0.88; and / or, 0.75≤(FJ) / M≤0.88; and / or, 0.6≤(GK) / N≤0.8.

[0154] With such configuration, the energy density in the battery compartment 20 is further improved by further limiting the size of the battery cell 520 in the battery compartment 20 .

[0155] By way of example, the volume ratio of the battery cells 520 in the battery compartment 20 can also be limited. For example, the volume of the battery compartment 20 can be set to U, and the volume of a single battery cell 520 can be set to V, and the total number of battery cells 520 in the battery compartment 20 is W; thus, the ratio of the volume of the battery compartment 20 to all battery cells 520 can be limited to 0.55≤VW / U≤0.95, preferably, 0.75≤VW / U≤0.85.

[0156] Please refer to Figures 1 to 3 A battery compartment door 21 for enclosing the battery compartment 20 is provided on one side of the box body 10 in the second direction P, and the other side of the box body 10 in the second direction P is in a closed structure; an electrical compartment door 31 for enclosing the electrical compartment 30 is provided on one side of the box body 10 in the first direction O, and the other side of the box body 10 in the first direction O is in a closed structure.

[0157] The battery compartment door 21 can be set on the box body 10; optionally, the battery compartment door 21 can be rotatably connected to the box body 10 through hinges, etc., and can be locked on the box body 10 through a door lock.

[0158] Optionally, the number of battery compartment doors 21 can be at least two, for example, there can be four battery compartment doors 21; at least two battery compartment doors 21 are arranged on the box body 10 along the first direction O and are used together to open or close the battery compartment 20 to perform operations and maintenance tasks inside the battery compartment 20.

[0159] In this way, among the circumferential sides of the box body 10, two intersecting sides are provided with door structures, and the other two intersecting sides are not provided with door structures. Therefore, the side of the box body 10 without door structure can be placed close to other boxes 10, so as to form a grid arrangement of four boxes 10.

[0160] Please refer to Fig. 9 In some embodiments, the electrical warehouse 30 includes at least one of a distribution box 32, a main control box (not shown in the figure), a fire control module 33, a fire pipeline (not shown in the figure), an explosion-proof fan (not shown in the figure), and a bus 34.

[0161] With such arrangement, at least one of the distribution box 32 , the master control box, the fire control module 33 , the fire pipeline, the explosion-proof fan, and the bus 34 can be accommodated in the electrical compartment 30 , achieving a compact arrangement.

[0162] Please refer to Figure 1 , Figure 2 and Fig. 9 In some embodiments, the fire control module 33 is disposed on the electrical compartment door 31 .

[0163] In this way, by setting the fire control module 33 on the electrical compartment door 31 , the spatial arrangement in the electrical compartment 30 can be improved, and the compactness of the electrical compartment 30 is effectively improved.

[0164] Please refer to Figure 1 and Figure 2 In some embodiments, the air outlet 80 of the explosion-proof fan is arranged on the electrical compartment door 31; in the second direction P, the air inlet 70 of the explosion-proof fan is arranged on the side of the battery compartment door 21 away from the electrical compartment door 31, and the air inlet 70 of the explosion-proof fan is located on the lower side of the third direction Q.

[0165] It can be understood that the third direction Q can be the direction of gravity in the working state. Therefore, the air inlet 70 of the explosion-proof fan is located on the lower side of the third direction Q, which means that the air inlet 70 of the explosion-proof fan is located in the lower area of ​​the electrical compartment door 31 in the direction of gravity.

[0166] Optionally, the air inlet 70 of the explosion-proof fan is closed by a baffle; the air outlet 80 of the explosion-proof fan is closed by a baffle.

[0167] A partition wall 90 is arranged between the electrical compartment 30 and the battery compartment 20, and a vent is arranged on the partition wall 90. The explosion-proof fan also includes an exhaust fan and a closed air duct arranged in the electrical compartment 30. The air duct is connected to the battery compartment 20 and the air outlet 80 through the vent, so that the thermal runaway gas of the battery 51 can be quickly discharged from the energy storage container 100.

[0168] In this way, the air outlet 80 of the explosion-proof fan is arranged on the electrical compartment door 31, and the air inlet 70 of the explosion-proof fan is arranged on the battery compartment door 21, so that the air inlet 70 and the air outlet 80 of the explosion-proof fan can be separated.

[0169] For example, in some specific embodiments, the energy storage container 100 includes a box body 10, in which a battery compartment 20 and an electrical compartment 30 and a liquid cooling unit 40 arranged on the same side of the battery compartment 20 along a first direction O are arranged, and the liquid cooling unit 40 is sequentially distributed along a second direction P; the battery compartment 20 contains four battery clusters 50 arranged sequentially along the first direction O, each battery cluster 50 includes eight batteries 51 arranged along a third direction Q, and a main control box 60 is arranged at the bottom of each battery cluster 50 in the third direction Q; through the above arrangement, the energy storage container 100 The space utilization is more reasonable, and the staff can check the electrical compartment 30 and the liquid cooling unit 40 on the same end side of the energy storage container 100, which effectively improves the convenience of on-site maintenance; when installing and configuring the energy storage container 100, the layout mode in which the electrical compartment 30 and the liquid cooling unit 40 are located on the same side can also improve the convenience of assembly. When multiple energy storage containers 100 are arranged, the battery compartments 20 of two adjacent energy storage containers 100 can also be placed against each other on one side, which can reduce the space occupied by the arrangement of multiple energy storage containers 100 to improve the energy storage density per unit area.

[0170] Please refer to Figure 1 and Figure 8 In the second aspect, the embodiment of the present application further provides an energy storage system 1000, including the energy storage container 100 as described above. The energy storage system 1000 provided in the embodiment of the present application includes the energy storage container 100 described above. On the basis of the high space utilization of the energy storage container 100, the energy storage system 1000 also has a high space utilization, so the energy storage density is also improved.

[0171] Please refer to Figure 1 and Figure 8 In some embodiments, two energy storage containers 100 are arranged along a first direction O to form a container group 1100, the battery compartments 20 of the two energy storage containers 100 in the container group 1100 are adjacent to each other, and the battery compartment doors 21 of the two energy storage containers 100 in the container group 1100 are located on the same side.

[0172] It can be understood that the two energy storage containers 100 are arranged along the first direction O, that is, arranged in a row along the length direction of the box body 10; wherein, the battery compartments 20 of the two energy storage containers 100 can be adjacent to each other, and at this time, the electrical compartments 30 of the two energy storage containers 100 in the container group 1100 are opposite to each other; that is, the box bodies 10 of the two energy storage containers 100 can be placed close to each other along the first direction O, and the two energy storage containers 100 are mirror-symmetrical, thereby, the battery compartments 20 of the two energy storage containers 100 can be adjacent to each other, and the electrical compartments 30 and the liquid cooling units 40 of the two energy storage containers 100 are respectively located at opposite ends in the first direction O.

[0173] Compared with the method of arranging two energy storage containers 100 at intervals, such an arrangement enables the two energy storage containers 100 to be close to each other and arranged in a row due to the structural design that the electrical compartment 30 and the liquid cooling unit 40 are located on the same end side of the battery compartment 20, thereby effectively reducing the total floor space occupied by the two energy storage containers 100, thereby improving the energy density per unit area of ​​the floor space; at the same time, since the electrical compartment 30 and the liquid cooling unit 40 of the two energy storage containers 100 are both located at the end, it will not affect the maintenance operation, and can also improve the convenience of on-site operation, that is, it is only necessary to operate the battery compartments 20 of the two energy storage containers 100 on the same side of the box body 10.

[0174] Please refer to Figure 1 and Figure 8 In some embodiments, there are two container groups 1100, and the two container groups 1100 are arranged in sequence along the second direction P, and the two container groups 1100 are distributed in a mirror image; wherein the second direction P is perpendicular to the first direction O, the first direction O is the length direction of the box body 10, and the second direction P is the width direction of the box body 10.

[0175] It can be understood that the width direction of the box body 10 of the above-mentioned energy storage container 100 can be parallel to the second direction P, and at the same time, the length direction of the box body 10 of the energy storage container 100 can be parallel to the first direction O, and the height direction of the box body 10 of the energy storage container 100 can be parallel to the third direction Q; the two groups of container groups 1100 are arranged in sequence along the second direction P of the energy storage container 100, that is, the two groups of container groups 1100 are arranged along the width direction of the box body 10; at this time, the two groups of container groups 11 00A total of four energy storage containers 100 are arranged in a grid pattern, and two energy storage containers 100 in the same container group 1100 are placed close to each other along the first direction O, and the two energy storage containers 100 are mirror-symmetrical; the containers in the two container groups 1100 are placed back to back, that is, the two energy storage containers 100 of one container group 1100 and the two energy storage containers 100 of the other container group 1100 are placed close to each other back to back, and the two container groups 1100 are distributed in a mirror-image manner.

[0176] In this configuration, the two groups of container groups 1100 are arranged along the second direction P and are distributed in a mirror image. As a result, the four energy storage containers 100 can be arranged close to each other in a grid-like manner. Compared with the manner of arranging the four energy storage containers 100 in an intermittent manner, the energy density per unit area occupied can be further improved; and the two groups of container groups 1100 are arranged in sequence, which can reduce the distance between the two groups of container groups 1100, thereby reducing the maintenance distance of the two groups of container groups 1100, so as to improve the convenience of on-site operation.

[0177] Please refer to Figure 1 and Figure 8 In some embodiments, the electrical compartments 30 of two energy storage containers 100 arranged in the second direction P are arranged adjacent to each other.

[0178] With such an arrangement, the electrical compartments 30 of the two energy storage containers 100 can be simultaneously observed and maintained on the same side in the second direction P, which effectively improves the convenience of maintenance.

[0179] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
