[0061] Now, the accompanying drawings will be referred to in describing the exemplary embodiments according to the present application. Figures 1 to 10 The exemplary embodiments according to the present application will be described in more detail.

[0062] The present application provides a container system 100 / 200 for storing batteries, control devices, etc. to realize the storage, conversion and output of electric power. The energy storage container system 100 / 200 includes a box body 10 and a first connecting piece 20. At least two box bodies 10 are arranged along the horizontal direction or along the height direction D2 of the box body 10, and the box body 10 has an angle piece 11. The first connecting piece 20 is detachably connected to the angle pieces 11 of the adjacent two box bodies 10, so as to fixedly connect the box bodies 10. The first connecting piece 20 is, for example, a twist lock. Among them, the size of the box body 10 in the length direction is 2.4m to 3.5m.

[0063] It can be understood that the horizontal arrangement is arranged substantially horizontally, and the height direction D2 of the box body 10 is arranged as the up-down stacking of the box body 10. The arrangement of the at least two box bodies 10 in the horizontal direction includes the arrangement of the at least two box bodies 10 in the length direction D1 of the box body 10, and also includes the arrangement in the width direction of the box body 10. For example, the box body 10 with a side door is arranged in the length direction D1. For example, the box body 10 with an end door is arranged in the width direction. The box body 10 can include a plurality of corner pieces 11, for example, the box body 10 includes four top corner pieces 11 and four bottom corner pieces 11. The corner piece 11 has a corner piece hole, and the first connecting piece 20 can be connected above the top corner piece 11 and below the bottom corner piece 11, and the first connecting piece 20 can be connected to the side of the top corner piece 11 and the side of the bottom corner piece 11, so as to connect the horizontally arranged box bodies 10.

[0064] As shown in Figure 1 , the container system 100 includes four box bodies 10 arranged in the height direction D2. The top and bottom of the box body 10 are provided with corner pieces 11, and the first connecting piece 20 is connected to the bottom corner piece 11 of the upper box body 10 and the top corner piece 11 of the lower box body 10 of the adjacent two box bodies 10, so as to combine the box bodies 10 and fully utilize the height space in the system arrangement site. Figure 2 As shown in Figure 2 , the container system 200 includes four box bodies 10 arranged in the length direction D1 of the box body 10. The bottom of the box body 10 is provided with a bottom corner piece 11, and the first connecting piece 20 connects at least one bottom corner piece 11 of the adjacent two box bodies 10, so as to combine the box bodies 10, and the length of the box body 10 is less than the length of the standard container, which can flexibly utilize the horizontal space of the site. Of course, the horizontally arranged box bodies 10 can connect at least one top corner piece 11 of the box body 10 through the first connecting piece 20, or the top corner piece 11 and the bottom corner piece 11 are connected through the first connecting piece 20.

[0065] The energy storage container system according to the utility model is combined by a plurality of box bodies and is detachably fixed and connected through connecting pieces, which is convenient to install and disassemble and facilitates flexible setting of the number of box bodies according to the site space. The container system includes a box body with a length smaller than that of a standard container and can be combined in the horizontal direction and the height direction, so as to more flexibly and fully utilize the site space.

[0066] Preferably, the size of the box body 10 in the height direction D2 is 1.7m to 2.5m, which is smaller than the height of the standard container, so as to more flexibly utilize the space in the height direction D2 and better stabilize the stacking of the box body 10 in the height direction D2.

[0067] Preferably, as shown in Figures 3 to 7As shown, the first connecting member 20 comprises a base, the base comprises a fixedly connected partition plate 21 and a first shock pad 22, the partition plate 21 and the first shock pad 22 respectively form two opposite end faces of the base. The first shock pad 22 is, for example, rubber. In the connected state of the first connecting member 20 and the corner piece 11, the partition plate 21 and the first shock pad 22 respectively abut the corner pieces 11 of the two adjacent box bodies 10. Thus, the first shock pad 22 can block the transmission of vibration between the box bodies 10, and protect the equipment in the box, especially to make the stability of the container system 100 arranged along the height direction D2 better.

[0068] It should be noted that the first shock pad 22 of different first connecting members 20 can be selected according to the weight range it needs to bear, and different hardness, thickness and size can be selected. The carrying capacity of a single first shock pad 22 is selected to correspond to a carrying capacity range of, for example, 600kg-16800kg. In the embodiment in which the box bodies 10 are arranged along the height direction D2, the first connecting member 20 with the first shock pad 22 can be used to connect between the two adjacent box bodies 10, or a common twist lock can be used to connect between the two adjacent box bodies 10. In the embodiment in which the box bodies 10 are arranged along the horizontal direction, the first connecting member 20 with the first shock pad 22 can be used to connect between the two adjacent box bodies 10, or a common twist lock can be used to connect between the two adjacent box bodies 10.

[0069] The other part of the structure of the first connecting member 20 can be arranged to be the same as the twist lock. For example, rotatable lock heads 25 are arranged at both ends of the first connecting member 20 in the axial direction Z, and the lock heads 25 are arranged to have different sizes in different directions perpendicular to the axial direction Z. Thus, after the lock heads 25 are inserted into the cavities of the corner pieces 11 from the corner piece holes, the lock heads 25 are locked with the corner pieces 11 by rotating the lock heads 25. The two lock heads 25 are used to lock with the corner pieces 11 of the two adjacent box bodies 10 respectively.

[0070] In some specific embodiments, the first connecting member 20 further comprises a first housing 23 and a first pivot shaft 24. The housing is a hollow structure, the first housing 23 comprises a first part and a second part, the first part and the second part are fixedly connected to the two sides of the partition plate 21 respectively. The partition plate 21 has a through hole, and the through hole of the housing is arranged correspondingly with the through hole of the partition plate 21, so that the first pivot shaft 24 is arranged through the through hole and is pivotably arranged in the first housing 23. The size of the first housing 23 in the direction perpendicular to the axial direction Z is smaller than the size of the partition plate 21, and the first shock pad 22 is sleeved on the outside of the first housing 23. Preferably, the outer contour of the first shock pad 22 is the same as the outer contour of the partition plate 21, and the outer peripheral size of the first shock pad 22 is the same as the outer peripheral size of the partition plate 21.

[0071] The first connecting member 20 comprises two locking heads 25, which are fixedly connected to the two ends of the first rotating shaft 24 respectively, and can rotate with the pivoting of the first rotating shaft 24. The two locking heads 25 are used to extend into the corner piece 11 of the adjacent container 10 respectively, and are locked or unlocked with the corner piece 11 through pivoting.

[0072] It can be understood that the sizes of the corner piece holes in the two directions perpendicular to each other or at an angle on the end face of the corner piece 11 are different, for example, the sizes of the locking heads 25 in the first direction and the second direction perpendicular to the axial direction Z are different, and the first direction and the second direction are perpendicular to each other or at an angle. The size of the outer contour of the locking head 25 in the plane perpendicular to the axial direction Z is slightly smaller than the size of the corner piece hole. Therefore, the locking head 25 can extend into the corner piece 11 through the corner piece hole, and after rotating around the axial direction Z, it can be clamped with the corner piece 11 without being separated from the corner piece 11. The two locking heads 25 can be rotated simultaneously through the first rotating shaft 24. Of course, the first connecting member 20 can be provided such that only one end of the locking head 25 rotates with the rotating shaft, and the other locking head 25 cannot be pivoted relative to the base. After the locking head 25 that cannot be pivoted relative to the base is extended into the corner piece 11, the locking head 25 is rotated by rotating the base.

[0073] In order to realize the rotation of the locking head 25 after the two locking heads 25 of the first connecting member 20 are extended into the corner piece 11, the partition plate 21 has a receiving cavity, and the first connecting member 20 further comprises a handle 26, which is partially located in the receiving cavity and connected with the first rotating shaft 24. The handle 26 can be rotated in the receiving cavity to drive the first rotating shaft 24 to rotate. Specifically, the handle 26 can be fixedly connected with the first rotating shaft 24, or transmission connection. For example, the handle 26 is transmission connected with the first rotating shaft 24 through a gear. Thus, the operator can drive the first rotating shaft 24 to rotate by rotating the part of the handle 26 outside the partition plate 21, thereby driving the locking head 25 to rotate, and realizing the locking or unlocking between the two adjacent containers 10.

[0074] Preferably, especially in the container system 100 provided along the height direction D2, the container system 100 further comprises a second connecting member 30. As shown in Figure 1 , Figures 8 to 10 The second connecting member 30 is detachably connected to the corner piece 11, specifically to the bottom corner piece 11 of the container 10, and the second connecting member 30 is used to be fixedly connected with the foundation. In this way, the container system 100 is more stable.

[0075] The design of the locking and unlocking of the second connecting member 30 with the corner piece 11 is substantially the same as that of the first connecting member 20. The difference is that the second connecting member 30 is provided with a locking head 25 only at the upper end. The second shock-absorbing pad 32 of the second connecting member 30 abuts against the foundation, and is supported together with the partition plate 21 between the foundation and the corner piece 11 of the container 10, thereby reducing the vibration of the container 10.

[0076] Specifically, the second connecting piece 30 comprises the partition plate 21, the bottom plate 31 and the second shock pad 32 connected in sequence. In the connected state of the second connecting piece 30 and the corner piece 11, the partition plate 21 and the second shock pad 32 abut against the corner piece 11 and the foundation, respectively. The bottom plate 31 and the second shock pad 32 are fixedly connected as a whole by the first fastener 33 (for example, a screw).

[0077] The second connecting piece 30 comprises the second fastener 34, the second shock pad 32, the bottom plate 31 and the partition plate 21 are provided with connecting holes, and the second fastener 34 passes through the connecting holes to fixedly connect the second connecting piece 30 with the foundation. For example, the second fastener 34 is a bolt, the bolt is pre-welded to the foundation, the bolt passes through the connecting holes of the second shock pad 32, the bottom plate 31 and the partition plate 21, and a nut is screwed to the bolt to fix, so as to fix the second connecting piece 30 to the foundation.

[0078] The second connecting piece 30 further comprises the second housing 35, the second pivot shaft 36 and the lock head 25. The second housing 35 is a hollow structure and is connected to the side of the partition plate 21 opposite to the second shock pad 32. The partition plate 21 has a through hole, the through hole of the second housing 35 is correspondingly arranged with the through hole of the partition plate 21, and the second pivot shaft 36 passes through the through hole and is pivotally arranged in the second housing 35. The lock head 25 is connected to the second pivot shaft 36, the lock head 25 is used to extend into the corner piece 11 and is locked or unlocked with the corner piece 11 by pivoting. The partition plate 21 has a receiving cavity, and the second connecting piece 30 further comprises a handle 26, the handle 26 is partially located in the receiving cavity and is connected with the second pivot shaft 36, and the handle 26 can rotate in the receiving cavity to drive the second pivot shaft 36 to rotate.

[0079] Among the plurality of box bodies 10 constituting the container system 100 / 200, at least one box body 10 is a control box for arranging control equipment to realize power conversion and output. At least one box body 10 is a battery box for arranging a battery cluster to realize power storage. The side wall of the battery box is provided with an interface for arranging a quick connector for connecting the battery cluster. One side wall of the battery box is provided with a groove with two open ends, and the groove is used to arrange a cable for connecting the battery box.

[0080] The battery packs in the battery box are connected in clusters with the direct current conversion area of the control box. Specifically, the direct current of each battery box is collected together, the cluster-level direct current cable is collected, and after being transformed, it is transmitted to the direct current / alternating current module to convert the direct current into the required alternating current and then output. Thus, the number of different direct current conversion devices can be customized according to each project to avoid over-provisioning.

[0081] The control box adopts a battery column design, and different types of support brackets are provided for different models of direct current / alternating current converters. One control box can meet the installation needs of multiple different types of converters. Therefore, different models and quantities of converters can be configured according to different projects.
