Description

Battery pack packaging body

Technical Field

The utility model mainly relates to the technical field of photovoltaic modules, in particular to a packaging body of a battery module.

Background

While the technology for manufacturing photovoltaic modules is continuously developed towards high power, the size of the modules is also increased. When the length or the width of the assembly is continuously increased, the size of a larger and larger packing box is required to meet the packing requirement of a large-size battery assembly, and the phenomenon that the packing box with the conventional fixed size cannot be matched with the large-size assembly frequently is caused, so that the space utilization rate of the packing box is reduced, and the like, and the problem of higher cost is caused.

Specifically, as shown in fig. 1, a conventional package 10 for a battery pack is provided. When a smaller-sized battery pack is placed in a conventional packing case 100 (e.g., a 40HC iso container), the packing manner as shown in fig. 1 may be generally used. The packing case 100 has two layers of partitions 13 therein. Wherein, the partition plate 13 located in the middle of the packing box 100 divides the packing box 10 into two independent packing spaces of an upper layer and a lower layer. The plurality of battery modules 12 of the upper layer and the plurality of modules 11 of the lower layer are arranged longitudinally in the respective upper and lower spaces, and the partition plate 13 at the bottom of the packing case 100 is particularly used to carry the plurality of battery modules 11 of the lower layer.

As can be seen from fig. 1, the size of the packaging box 100 is just enough to accommodate a plurality of battery modules 11 and a plurality of battery modules 12 of the same size, which are vertically arranged in two layers. At this time, if the size of the battery modules 11 and/or 12 is increased due to the production requirement in order to obtain a photovoltaic module with a higher power, the same packaging box 100 (e.g. a 40HC international standard container) cannot be used for placing the photovoltaic modules in the upper and lower layers according to the packaging manner shown in fig. 1, for example, a phenomenon that only one layer of large battery modules is vertically placed and the packaging box 100 has a residual space may occur, thereby causing a more serious cost problem such as a low space utilization rate of the packaging box.

Fig. 2 is a schematic flow chart illustrating a packaging manner of a battery pack according to an embodiment of the utility model, as shown in fig. 2. Fig. 3 is a sectional view of a package body 30 of a battery pack according to an embodiment of the present invention.

In one embodiment of the present invention, the package 20 shown in fig. 2 is used to form a package 30 of a battery pack shown in fig. 3.

It should be understood that the present invention is not limited thereto, and for example, in some other embodiments of the present invention, the packaging method 20 shown in fig. 2 is adopted, and other forms of packages may be formed. Alternatively, the package 30 of the battery pack shown in fig. 3 may be formed by a packaging method different from the packaging method 20 shown in fig. 2. The packaging 20 shown in fig. 2 and the packaging 30 of the battery pack shown in fig. 3 are therefore not limiting to each other.

For better understanding of the package 30 of a battery pack of the present application, the package 30 of a battery pack of the present invention in this embodiment will be described below with reference to fig. 2 and 3.

Fig. 2 uses a flowchart in this application to illustrate the operations performed by a system according to embodiments of the present application. It should be understood that the preceding or following operations are not necessarily performed in the exact order in which they are performed. Rather, various steps may be processed in reverse order or simultaneously. Meanwhile, other operations are added to or removed from these processes.

As shown in fig. 2, according to the packaging method 20 of the battery pack 30 shown in fig. 3 of the present invention, a plurality of battery packs 31 and a plurality of battery packs 32 can be placed in a packaging box 300, and the packaging box 300 includes two separating layers 33, and the separating layers 33 separate the packaging box 300 into two independent packaging spaces, namely a packaging space 301 and a packaging space 302, in the packaging box 30 shown in fig. 3.

The packaging 20 shown in fig. 2 comprises the following steps:

step 21: setting the position and the number of the separation layers according to the size of the battery assembly;

step 22: configuring a buffer layer; and

step 23: a plurality of battery packs are placed in each packaging space, and the placement modes of the battery packs are different between at least two packaging spaces.

In the above embodiment, if the package method 20 shown in fig. 2 is adopted to finally form the package body 30 shown in fig. 3, the step 21 in the package method 20 is: the number of the partition layers 33 is set to 2 according to the size of the battery module, and the two partition layers 33 are respectively located at the middle position and the bottom position of the packing case 300.

For example, in one embodiment of the present invention, the packing box 30 is a 40HC container commonly used for packing battery modules, and has a size of 12 × 2.35 × 2.69 m and a door height of 2.58 m, and when the module width is more than 1.3 m, the above-mentioned 2 partition layers 33 can be selected and the two partition layers 33 are respectively located at the middle position and the bottom position of the packing box 300.

It will be appreciated that in some other embodiments of the utility model, the number and location of the spacer layers 33 may be varied for different sizes of the packaging case 300 and the size of the battery modules 31 and/or 32 to be packaged.

Further, in the above embodiment, if the packaging method 20 shown in fig. 2 is adopted to finally form the packaging body 30 shown in fig. 3, the step 23 in the packaging method 20 is to place a plurality of battery modules 31 and a plurality of battery modules 32 in each of the packaging spaces 301 and 302, and as can be seen from fig. 3, the placement of the plurality of battery modules 31 and the placement of the plurality of battery modules 32 are different between the two independent packaging spaces 301 and 302.

In the packaging space 301, the battery assemblies 31 are arranged vertically, and in the packaging space 302, the battery assemblies 32 are stacked parallel to the bottom of the packaging box 300.

As described above, the package 20 shown in fig. 2 of the present invention is not limited by the package 30 shown in fig. 3, and in some other embodiments of the present invention, the package formed by the package 20 shown in fig. 2 may be formed into other forms of packages, and the other forms of packages may have more than two separate layers and more independent package spaces, but the arrangement of the battery modules is different between at least two independent package spaces.

Moreover, the different placement modes are not limited to the combination of vertical placement and stacking as shown in the package 30 shown in fig. 3, and other placement modes besides vertical placement and stacking may be selected according to the actual production needs.

Further, in the packaging method 20 shown in fig. 2, step 22 is to dispose a buffer layer. The buffer layer is configured in such a manner that the buffer layer is adhered to one of the adjacent two battery modules. In some embodiments of the present invention, the buffer layer may be partially or completely covered on one surface of the battery module by a buffer pad, a buffer sponge, or the like.

It is understood that, in order to obtain better buffering effect, in some other embodiments of the present invention, a buffering layer may be disposed between the battery assembly and the packaging box at the edge of the packaging box, so as to prevent the packaging box from squeezing or damaging the battery assembly.

In one embodiment of the present invention, a battery pack packaging system 20 as shown in fig. 2 may be used to package the battery pack shown in fig. 4 a-4 b. In this embodiment, as shown in fig. 4a, the packaged battery pack 32 or 31 has ribs 40 on its surface to provide support for the large battery pack and prevent the long sides of the battery pack from breaking during handling.

As shown in fig. 4b, for the battery assembly 32 or 31 having the reinforcing rib, when the buffer layer is configured in step 22, the buffer layer 34 can be adhered to the reinforcing rib 40, so as to enhance the buffer effect of the buffer layer, and effectively reduce the stress of the assembly when the large-size assembly is laid flat and stacked, thereby reducing the risk of the hidden crack of the battery piece when the assembly is accidentally stressed.

Fig. 4a to 4b only show the case that the battery pack has one reinforcing rib, but the present invention is not limited thereto, and in other embodiments of the present invention, the battery pack further has a plurality of reinforcing ribs larger than one, and the buffer layer may be suitably selected from the plurality of reinforcing ribs, and some or all of the plurality of reinforcing ribs may be adhered.

It is understood that in some other embodiments of the present invention, the step of configuring the buffer layer may be omitted, and only steps 21 and 23 are retained, so that the technical effect of reasonably utilizing the space of the packing box can be achieved.

The packaging method 20 shown in fig. 2 can fully utilize the space of the packaging box. For example, when a battery assembly is packed, the size of a 40HC packing box is 12 × 2.35 × 2.69 m, the door height is 2.58 m, and when the width of the assembly reaches more than 1.3 m, according to the conventional practice in the industry, a large amount of space of the packing box is wasted by adopting the conventional arrangement mode shown in fig. 1, which causes problems of cost and the like.

The packaging mode shown in fig. 2 is adopted, the space of the packaging box can be utilized to the maximum extent by using the combined placing mode of vertical placing and stacking in different packaging spaces, so that the cost is saved, and the stress of the components when the large-size components are horizontally placed and stacked can be reduced by configuring the buffer layer, so that the risk of hidden cracking of the components under the condition of accidental stress is reduced.

For a better understanding of the package 30, the package 30 has been described initially in terms of its manner of use in conjunction with FIG. 2, and a more systematic and complete description of the package 30 is provided below.

As shown in fig. 3 and 4b, the packing body 30 includes a packing case 300, a plurality of battery assemblies 31 and a plurality of battery assemblies 32, and a buffer layer 34, wherein the buffer layer 34 is not shown in the cross-sectional view of fig. 3 for keeping the drawing simple because it is located between two adjacent battery assemblies, and as can be seen from fig. 4b, in this embodiment shown in fig. 4b, the buffer layer 34 has a long bar shape.

However, the present invention is not limited thereto, and fig. 5 is an enlarged schematic view of a surface of a battery module in a package of the battery module according to an embodiment of the present invention. In the embodiment shown in fig. 5, the cushioning layer 34 includes a plurality of cushioning pads dispersedly adhered to the battery assembly. In fig. 5, the battery assembly 32(31) also has the reinforcing ribs 40, so that a plurality of cushion pads can be intermittently adhered to the reinforcing ribs 40, thereby achieving the cushioning effect and saving the cost.

In the embodiment shown in fig. 4b, the length of the buffer layer is the same as that of one side of the battery assembly, and the width of the buffer layer is much smaller than that of the other side of the battery assembly, but the present invention is not limited thereto. For example, the buffer layer 34 may cover a larger area of the surface of the cell assembly.

In addition, in the embodiment shown in fig. 4b, the battery assembly 32(31) is a battery assembly having a reinforcing rib, and the cushioning layer 34 is attached to the battery assembly 32 or 31, and wraps the reinforcing rib, that is, the cushioning layer 34 is located at the position of the reinforcing rib 40, so that the cushioning effect can be enhanced.

Similarly, fig. 4a to 4b only show the case where the battery module has one reinforcing rib, but the present invention is not limited thereto, and in other embodiments of the present invention, the battery module further has a plurality of reinforcing ribs larger than one, and the buffer layer may be suitably selected from the plurality of reinforcing ribs, and some or all of the plurality of reinforcing ribs are adhered and wrapped.

It is understood that in the embodiment shown in fig. 3, the buffer layer 34 may be configured for various battery modules in different positions, or may be configured only in stacking, and the utility model is not limited thereto.

Further, in the embodiment shown in fig. 3, the packing case 300 includes two partition layers 33, and the partition layer 33 located at the middle of the packing case 300 divides the packing case 300 into two independent packing spaces.

However, the present invention is not limited thereto, and in some other embodiments of the present invention, the packing box may have more separating layers and independent packing spaces, or more separating layers may be located at other positions to achieve different dividing effects for the packing spaces.

In the embodiment shown in fig. 3, the packing body 30 further includes a plurality of battery packs, which are divided into a plurality of battery packs 32 and a plurality of battery packs 31 according to their arrangement positions, the plurality of battery packs 32 and the plurality of battery packs 31 are respectively arranged in two independent packing spaces 302 and 301, and the arrangement patterns of the plurality of battery packs 32 and the plurality of battery packs 31 are different between the two packing spaces 302 and 301.

Specifically, as shown in fig. 3, the plurality of battery assemblies 31 are arranged vertically, and the plurality of battery assemblies 32 are arranged in a stacked manner. However, the present invention is not limited thereto, and in some other embodiments of the present invention, the battery assembly may have other different arrangement manners.

In some other embodiments of the present invention, the packing case 300 has more separating layers and packing spaces, but the arrangement of the battery modules is different between at least two of the packing spaces.

In some other embodiments of the present invention, the battery packs in a certain packaging space are arranged differently. For example, in the same packaging space, a combination of vertical placement and stacking can be adopted, so that the space of the packaging box is fully utilized.

In an embodiment of the utility model, the packaging box related in the packaging body of the battery component comprises an international standard container, and the container has an international standard fixed size, so that under the condition that the size cannot be changed, different placing modes are selected for combination and the buffer layer is configured, so that the space of the packaging box can be fully utilized, the stress of the component when the large-size component is flatly placed and stacked is reduced, and the risk of hidden cracking of the component under the condition of accidental stress is reduced.
