[0050] The core of this application is to disclose an energy storage box body to reduce the transportation cost of the energy storage box body.

[0051] Another core of this application is to disclose an energy storage system including the above-mentioned energy storage box body.

[0052] Hereinafter, the embodiments will be described with reference to the drawings. In addition, the embodiments shown below do not limit the content of the utility model recorded in the claims in any way. In addition, all the contents of the constitution shown in the following embodiments are not limited to those necessary for the solution of the utility model recorded in the claims. It should be noted that for the convenience of description, only the parts related to the utility model are shown in the drawings. Without conflict, the embodiments in this application and the features in the embodiments can be combined with each other.

[0053] Combined with Figure 1 、 Figure 2 、 Figure 9 and Figure 10 The energy storage box body disclosed in this application includes a battery compartment 100, battery packs 110 and a first wire bundling site. A plurality of battery packs 110 are arranged in the battery compartment 100. Two battery packs 110 defined for being electrically connected through the first power line 200 are respectively a first battery pack 111 and a second battery pack 112. Then, the first wire bundling site is arranged in the battery compartment 100, and the first power line 200 is fixedly arranged on the first wire bundling site.

[0054] To ensure the safety of the power line aviation plug connector and the energy storage box body, during the transportation of the energy storage box body, it is not allowed to connect and communicate between all adjacent or non-adjacent battery packs 110. That is, the two ends of the first power line 200 cannot be connected to the first battery pack 111 and the second battery pack 112 at the same time. In this application, through the setting of the first wire tying point, the fixed points of the first power line 200 can be increased. During transportation, by fixing the first power line 200 on the first wire tying point and on the first battery pack 111 or the second battery pack 112, the first power line 200 can have two fixed points, increasing the reliability of the fixation of the first power line 200, avoiding the free shaking of the first power line 200 during transportation, and thus enabling the first power line 200 to be shipped together with the battery pack 110. And because the first power line 200 is pre-fixed to one of the first battery pack 111 and the second battery pack 112 (hereinafter, the specific implementation is described as the first power line 200 being fixedly connected to the first battery pack 111 during transportation and having no connection relationship with the second battery pack 112. The implementation where the first power line 200 is fixedly connected to the second battery pack 112 during transportation and has no connection relationship with the first battery pack 111 can be referred to each other and will not be elaborated), during on-site assembly, only the first power line 200 needs to be electrically connected to the other one of the first battery pack 111 and the second battery pack 112, reducing the on-site wiring operation process of the operators, reducing the on-site manual assembly cost, shortening the assembly time, and the pre-assembled first power line 200 can also greatly reduce the probability of failures in on-site manual assembly.

[0055] Compared with the prior art, the energy storage box body disclosed in this application increases the fixed points of the first power line 200 through the setting of the first wire tying point, can realize the position fixation of the first power line 200 between adjacent battery packs 110, so that the first power line 200 can be transported together with the battery pack 110 without separate shipping, reducing the transportation cost and improving the on-site assembly efficiency of the energy storage box body.

[0056] Those skilled in the art can understand that the battery compartment 100 is mainly used to place the battery packs 110 (PACK). Combining Figure 6 and Figure 11 , there are usually multiple battery packs 110 stacked in a regular matrix in the battery compartment 100 (and the first battery pack 111 and the second battery pack 112 are usually two adjacent battery packs 110 in the battery compartment 100). The two adjacent battery packs 110 in different columns are connected by the first power line 200, and the battery packs 110 at the ends are connected to energy storage configuration devices such as the busbar cabinet 120, switch box, and PCS through the second power line.

[0057] Specifically, the first wire-tying site can be directly set at positions such as the door posts and the door of the battery compartment 100, or the first wire-tying site can also be set by adding a wire-tying plate structure (the first wire-tying plate 300) inside the battery compartment 100. Specifically, the first wire-tying plate 300 is provided with wire-tying holes, and the first power line 200 can be detachably fixed by a wire tie or a clamp 311 to prevent the first power line 200 from moving relative to the first wire-tying plate 300.

[0058] Combined Figure 9 with Figure 15 , first plug connectors 201 and second plug connectors 202 are respectively arranged at both ends of the first power line 200. The first plug connector 201 is used for plugging and electrically connecting with the first battery pack 111, and the second plug connector 202 is used for plugging and electrically connecting with the second battery pack 112. Among them, the first wire-tying site can be directly connected to the first power line 200 or connected to the first power line 200 through the second plug connector 202.

[0059] In the case where the first wire-tying site is directly connected to the first power line 200, in order to prevent wiring errors between the first plug connector 201 and the first battery pack 111 by operators, the length of the first power line 200 is defined as L, the position where the first power line 200 is fixed to the first wire-tying site is the fixed site, the extended length of the first power line 200 between the first plug connector 201 and the fixed site is L1, and the extended length of the first power line 200 between the second plug connector 202 and the fixed site is L2 (L = L1 + L2). The first battery pack 111 for plugging with the first plug connector 201 is the first target battery pack, and the remaining battery packs 110 are non-target battery packs. The site on the first target battery pack 111 for plugging with the first plug connector 201 is the first target plugging site. Then, the distance between the first target plugging site and the fixed site is less than L1, and the distance between the plugging sites of the non-target battery packs and the fixed site is greater than L1.

[0060] After the first power line 200 is fixed to the first wire-tying site, the first power line 200 can rotate at multiple angles around the fixed site (the first wire-tying site). By setting that within the spatial range at a distance within L1 from the fixed site, only the plug interface (the first target plugging site) on the first battery pack 111 (the first target battery pack) corresponding to the first plug connector 201 exists, the first plug connector 201 can only be connected to the corresponding first battery pack 111 and cannot be connected to other battery packs 110, thereby realizing the protection of active safety and the anti-fooling design, and improving the safety of the energy storage box body.

[0061] Alternatively, in the case where the first wire tying site is directly connected to the first power line 200, to avoid the situation of wiring errors when the operator connects the second aviation plug joint 202 and the second battery pack 112 on site, combined with Figures 6 - 9 and Figure 14 and Figure 15 , define the length of the first power line 200 as L, the position where the first power line 200 is fixed to the first wire tying site as the fixed site, the extended length of the first power line 200 between the first aviation plug joint 201 and the fixed site as L1, and the extended length of the first power line 200 between the second aviation plug joint 202 and the fixed site as L2 (L = L1 + L2). The second battery pack 112 for plugging into the second aviation plug joint 202 is the second target battery pack, and the remaining battery packs 110 are non-target battery packs. The site on the second target battery pack for plugging into the second aviation plug joint 202 is the second target plugging site. Then, the distance between the second target plugging site and the fixed site is less than L2, and the distance between the plugging site of the non-target battery pack and the fixed site is greater than L2.

[0062] After the first power line 200 is fixed to the first wire tying site, the first power line 200 can rotate at multiple angles around the fixed site (the first wire tying site). By setting that within the space range where the distance from the fixed site is within L2, there is only the plug interface (the second target plugging site) on the second battery pack 112 (the second target battery pack) corresponding to the second aviation plug joint 202, so that the second aviation plug joint 202 can only be connected to the corresponding second battery pack 112 and cannot be connected to other battery packs 110, thus avoiding the situation of fire caused by short circuit of the battery pack 110 due to wiring errors by the operator, realizing the protection of active safety and the anti-fool design, and improving the safety of the energy storage box.

[0063] To further avoid the situation of the first power line 200 moving randomly during transportation, in some embodiments, the energy storage box further includes a second wire tying site arranged in the battery compartment 100. The first wire tying site is used to connect to the first power line 200, and the second wire tying site is used to connect to the second aviation plug joint 202 or the first power line 200. By setting the second wire tying site, the fixed sites of the first power line 200 are further increased, and the first power line 200 can be further fixed and protected during transportation.

[0064] Among them, the second wire tying site can be specifically set directly at positions such as the door posts and the door of the battery compartment 100, or a wire tying plate structure (the second wire tying plate 310) can be added inside the battery compartment 100 as the second wire tying site. Specifically, a plurality of fixing holes are provided on the second wire tying plate 310. According to the actual number and layout positions of the first power lines 200, a plurality of clamps 311 are correspondingly installed on the second wire tying plate 310. The detachable disassembly connection of the second aviation plug joint 202 can be realized through the clamps 311, and the disassembly and assembly are convenient. The clamps 311 can also be fixed with reusable detachable cable ties. Compared with cable ties, the disassembly and assembly of the second aviation plug joint 202 and the detachable clamps 311 are more convenient.

[0065] Combined with Figure 4 and Figure 5 , in an embodiment, the first wire tying plate 300 is arranged between the first battery pack 111 and the second battery pack 112. The second wire tying plate 310 can also be arranged between the first battery pack 111 and the second battery pack 112 or as Figure 4 shown, arranged between the battery pack 110 and the door of the battery compartment 100, and the first power line 200 or the second aviation plug joint 202 is detachably arranged on the second wire tying plate 310. Combined with Figures 3 - 5 , it is preferably to fix the second aviation plug joint 202 on the second wire tying plate 310 to tightly fix the second aviation plug joint 202 on the second wire tying plate 310 during transportation, so as to protect the second aviation plug joint 202 and prevent it from being damaged by collision during transportation. Correspondingly, the first power line 200 can also be fixed to a certain extent.

[0066] Combined with Figure 9 , during transportation, the first power line 200 has three fixing sites. The first is the plugging and fixing site between the first aviation plug joint 201 and the first battery pack 111, the second is the fixing site between the middle position of the first power line 200 and the first wire tying plate 300 (the first wire tying site), and the third is the detachable fixing site between the first power line 200 near the second aviation plug joint 202 and the second wire tying plate 310 (the second wire tying site) or the detachable fixing site between the second aviation plug joint 202 and the second wire tying plate 310 (the second wire tying site). Combined with Figures 11 - 13 , when the energy storage box body is transported to the site for wiring and assembly of the energy storage box body, the detachable connection between the first power line 200 or the second aviation plug joint 202 and the second wire tying plate 310 can be directly released, and then the second aviation plug joint 202 can be inserted into the second battery pack 112.

[0067] For the convenience of fixation, the second battery pack 112 for plugging and connecting with the second aviation plug connector 202 is defined as the target battery pack, and the position where the target battery pack is plugged and connected with the second aviation plug connector 202 is the target plug position, and the distance between the first binding position and the target plug position is L3, and the distance between the second binding position and the target plug position is L4, then L3 is greater than L4, that is, the second fixing position is set closer to the target plug position than the first fixing position, so as to reduce the length required for fixing the first power line 200.

[0068] For some first power lines 200 with thicker wiring harnesses, a certain extension gap needs to be set between the first binding position and the second binding position to allow the first power line 200 to extend and avoid damage caused by excessive bending of the first power line 200.

[0069] In a specific embodiment disclosed in the present application, a second wire tie plate 310 is slidably provided in the battery compartment 100, and the second wire tie position is provided on the second wire tie plate 310. When the second wire tie plate 310 is in the first extreme sliding position, there is an extended gap between the first wire tie position and the second wire tie position. When the second wire tie plate 310 is in the second extreme position, there is an operating gap between the first wire tie position and the second wire tie position. The operating gap is larger than the extended gap, so that the operator can perform disassembly and assembly operations of the first power line 200 and the second wire tie plate 310 in the operating gap.

[0070] Combine Figure 4 and Figure 6 The second tie plate 310 and the first tie plate 300 can correspond to each other one-to-one and be provided with the aforementioned extended gap, with the clamp 311 disposed within the extended gap. The first tie plate 300 can be positioned between the gap between the first battery pack 111 and the second battery pack 112, while the second tie plate 310 can be positioned outside the gap between the first battery pack 111 and the second battery pack 112. When the door of the battery compartment 100 is open, the operator can move the second tie plate 310 to the second limit position to convert the extended gap into an operating gap, and then remove the second aviation connector 202 from the second tie plate 310 or install the second aviation connector 202 onto the second tie plate 310. After the operation is completed, the operator moves the second tie plate 310 to the first limit position to convert the operating gap into an extended gap, thereby reducing the space occupied within the battery compartment 100 and preventing collisions between the second tie plate 310, the second aviation connector 202, and the compartment door.

[0071] Combine Figure 16, the second aviation plug connector 202 is detachably fixed to the side of the second wire bundling plate 310 facing the first wire bundling plate 300 through a clamp 311. In order to define the limit position of the relative movement of the second wire bundling plate 310 with respect to the first wire bundling plate 300, corresponding limit members can be provided on the battery compartment 100 (the limit members limit the length of the slide rail in the battery compartment 100, and the second wire bundling plate 310 slides along the slide rail), or limit members (such as limit baffles, not shown in the figure) can be provided on the side of the second wire bundling plate 310 facing the first wire bundling plate 300. When the second wire bundling plate 310 slides to the first limit position, restricted by the limit members, the second wire bundling plate 310 cannot move further, and at this time, there is an extension gap between the second aviation plug connector 202 and the first wire bundling plate 300 to prevent the clamp 311 and the second aviation plug connector 202 from colliding with the first wire bundling plate 300. When the second wire bundling plate 310 slides to the second limit position, there is the above-mentioned operation gap between the first wire bundling plate 300 and the second wire bundling plate 310.

[0072] Combined Figure 16 , the parallel arrangement of the first wire bundling plate 300 and the second wire bundling plate 310 is beneficial to reducing the space occupation. The second wire bundling plate 310 can also be arranged at a certain angle (such as perpendicular) relative to the first wire bundling plate 300. When the angle between the first wire bundling plate 300 and the second wire bundling plate 310 is relatively large, there is no need to set a slidable structure for the second wire bundling plate 310 relative to the first wire bundling plate 300, and there can still be enough gaps between the first wire bundling plate 300 and the second wire bundling plate 310 for the disassembly and assembly operation of the second aviation plug connector 202. At this time, the second wire bundling plate 310 can be directly detachably arranged on the first wire bundling plate 300.

[0073] In some embodiments, the second wire bundling plate 310 is detachably arranged in the battery compartment 100 through a connecting member (such as a bolt), which is convenient to directly remove the second wire bundling plate 310 from the energy storage box body after the assembly of the energy storage box body is completed, avoiding affecting the wiring and reducing the space occupation of the second wire bundling plate 310.

[0074] The energy storage box body generally includes a busbar cabinet 120, a switch box, a PCS (power conversion system) and other energy storage configuration devices (the energy storage configuration devices and the battery compartment 100 are jointly arranged in the cabinet of the energy storage box body. The busbar cabinet 120 is used to realize the busbar function, the switch box is used to provide the control, protection and distribution functions of the circuit, and the PCS is used to realize the electric energy conversion. This is the prior art and will not be elaborated here). Some battery packs 110 in the battery compartment 100 are electrically connected to the energy storage configuration devices through the second power line. A third wire bundling site (such as a third wire bundling plate) is provided between the energy storage configuration devices and the battery packs 110, and the second power line is used to be detachably arranged on the third wire bundling site.

[0075] During transportation, the second power line is fixed at the third wire-tying site and is electrically connected to one of the battery pack 110 and the energy storage configuration device, and has no connection with the other. That is, the second power line is electrically connected to the battery pack 110 and has no connection with the energy storage configuration device, or the second power line has no connection with the battery pack 110 and is electrically connected to the energy storage configuration device, so as to achieve the safety protection of the battery pack 110 and the energy storage configuration device during transportation.

[0076] Furthermore, the energy storage box body may further include a fourth wire-tying site (for example, a fourth wire-tying board) to detachably fix the second power line during transportation. The fixing mechanism of the fourth wire-tying site for the second power line is similar to the fixing mechanism of the second wire-tying site for the first power line 200, which will not be elaborated here. In addition, other structures of the energy storage box body may refer to the prior art, which will not be elaborated here.

[0077] The energy storage system disclosed in this application includes the above-mentioned energy storage box body, so it also has the above-mentioned structures and beneficial effects. Other structures refer to the prior art, which will not be elaborated here.

[0078] The above description of the disclosed embodiments enables those skilled in the art to implement or use this application. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of this application. Specific technical means in some embodiments can be partially or wholly incorporated into another embodiment on the premise that they are not explicitly excluded by another embodiment. Therefore, this application will not be limited to these embodiments shown herein, but will conform to the broadest scope consistent with the principles and novel features disclosed herein.
