When disassembling the battery core 1, the battery core 1 is pushed out along the slide groove 224. The installation and disassembly of the battery core 1 are simple and convenient.

[0042] In this embodiment, the number of the interlayer racks 22 is not limited and can be set according to actual needs. The number of the interlayer racks 22 can be two or more, and multiple pairs of interlayer racks 22 are spaced apart along the vertical direction and / or horizontal direction of the battery compartment 10 to accommodate more battery cells 1.

[0043] In this embodiment, the material of the frame 21 and the interlayer frame 22 is not limited. The frame 21 and the interlayer frame 22 can be made of aluminum alloy, stainless steel, polycarbonate or other materials.

[0044] In one embodiment, Figure 3 As shown, the slide groove 224 is arranged on the interlayer frame 22, the side wall 221 is fixedly connected to the frame body 21, the slide groove 224 has an opening toward the battery core 1, the battery core 1 includes a body 11, the slider 12 is arranged on the outer side wall 221 of the body 11, and the slider 12 extends in a direction close to the slide groove 224.

[0045] In a preferred embodiment, the second connecting wall 223 contacts the lower end surfaces of the slider 12 and the body 11 at the same time, and the width of the second connecting wall 223 is greater than the width of the first connecting wall 222, which can increase the contact area between the second connecting wall 223 and the battery core 1 and improve the supporting effect of the second connecting wall 223.

[0046] In some embodiments not shown, the slide groove 224 is disposed on the outer side wall 221 of the battery core 1 , the slider 12 is disposed on the interlayer frame 22 , the protrusion and the groove extend along the length direction of the battery core 1 , and the protrusion is inserted into the groove.

[0047] In some embodiments not shown in the figure, an elastic layer (not shown in the figure) is provided between the chute 224 and the slider 12, and the chute 224 and the slider 12 are respectively in close contact with the elastic layer and squeeze the elastic layer. In this embodiment, the elastic layer can be fixedly connected to the inner wall surface of the chute 224 or the outer wall surface of the slider 12. On the one hand, the elastic layer has a certain elasticity. When installing the battery core 1, the chute 224 and the slider 12 squeeze the elastic layer, so that the contact between the chute 224, the slider 12 and the elastic layer is tighter and firmer, and the slider 12 is not easy to move in the chute 224, thereby improving the stability of the installation of the battery core 1; on the other hand, the elastic layer plays a role of buffering and shock absorption in the process of transporting the battery core 1, and can play a certain protective role for the battery core 1; in addition, when installing or removing the battery core 1, it is only necessary to apply a certain external force to the elastic layer to deform the elastic layer and reduce the squeezing force between the contact surface of the chute 224 and the slider 12, so as to easily push or push the slider 12 out of the chute 224, and the installation or removal of the battery core 1 is simple and convenient.

[0048] In this embodiment, the elastic layer is made of a high temperature resistant, wear resistant, and high toughness elastic material.

Specifically, the first limiter 23 contacts the front end surface of the battery core 1, and the second limiter 24 contacts the rear end surface of the battery core 1. The first limiter 23 and the second limiter 24 can provide the battery core 1 with a limiting and fixing function in the front-to-back direction. The first limiter 23, the second limiter 24 and the interlayer frame 22 cooperate with each other to provide a limiting and fixing function for the battery core 1 in the front-to-back direction, the left-to-right direction, and the up-and-down direction, so that the battery core 1 is fixed more firmly.

[0050] In this embodiment, the positions of the first limiting member 23 and the second limiting member 24 are not limited. The first limiting member 23 and the second limiting member 24 can be fixed on the side wall 221 , the first connecting wall 222 and / or the second connecting wall 223 .

[0051] In a preferred embodiment, Figures 5 to 7 As shown, the first stopper 23 and the second stopper 24 can be detachably connected to the interlayer frame 22 by means of buckles, screws or other fasteners. The first stopper 23 and the second stopper 24 are detachably connected to the interlayer frame 22. When installing or removing the battery cell 1, the first stopper 23 and the second stopper 24 can be removed to release the blocking effect on the battery cell 1, thereby facilitating the battery cell 1 to be pushed into or out of the interlayer frame 22.

[0052] According to the embodiments of the present utility model, Figure 3 As shown, an energy storage container 100 is also provided, including a first container 101 .

[0053] In this embodiment, the first container 101 only contains the battery compartment 10. The space size of the battery compartment 10 in the first container 101 is not restricted by other compartments. The first container 101 can free up more space to arrange the battery compartment 10 and load more battery cells 1, effectively improving the energy density of the system. In addition, the energy storage container 100 no longer sets the battery compartment 10 as a compartment module in the container, which is conducive to the separate design, manufacture, commissioning, maintenance and storage of the battery compartment 10.

[0054] In this embodiment, the protection level of the box body 20 is not lower than IP54, and it also has an anti-ultraviolet function to ensure that the box body 20 and the battery compartment 10 will not be overheated due to ultraviolet radiation.

The control box 31 can monitor, control, manage, communicate and exchange data, as well as diagnose and maintain the battery cell 1. The control box 31 is arranged beside the battery rack 2, and the control box 31 occupies a small space, making the structure of the battery compartment 10 more compact and the space utilization rate in the box body 20 higher; in addition, compared with setting the control box 31 at the bottom of the battery compartment 10, the control box 31 is set on the left or right side of the battery compartment 10, which is more convenient for maintenance personnel to repair the control box 31.

[0056] In one embodiment, Figure 2 As shown, the energy storage container 100 also includes a second container 102. The first container 101 and the second container 102 are detachably connected, and the first container 101 and the second container 102 are stacked. The height of the first container 101 is H1, the height of the second container 102 is H2, and H1+H2=H, where H is the height of a standard container.

[0057] In this embodiment, the sum of the heights of the first container 101 and the second container 102 is the same as the height of a standard container. After the first container 101 and the second container 102 arrive at the port, the first container 101 and the second container 102 are connected and fixed by a twist lock 4, and can be directly hoisted for sea transportation or loaded onto a truck for transportation without having to transport them separately, thereby saving transportation costs.

[0058] In a preferred embodiment, the first container 101 and the second container 102 have the same structure and height, that is, the height of the first container 101 and the height of the second container 102 are both 0.5H.

[0059] According to an embodiment of the present invention, a power generation system is also provided, including the battery compartment 10 as described above or the energy storage container 100 as described above.

[0060] In this embodiment, the battery compartment 10 of the power generation system is provided with a slide groove 224 and a slider 12 that cooperate with each other on the interlayer frame 22 and the battery cell 1. The slider 12 and the slide groove 224 provide a guide for the battery cell 1, so that the battery cell 1 is quickly, accurately and firmly fixed on the battery rack 2. The installation and fixation of the battery cell 1 is convenient and the installation efficiency is high. In addition, the first container 101 of the power generation system only includes the battery compartment 10. The spatial size of the battery compartment 10 in the first container 101 is not restricted by other compartments. The first container 101 can free up more space to arrange the battery compartment 10, and can load more battery cells 1, thereby effectively improving the energy density of the power generation system.
