Description

Technical Field

[0001] This utility model belongs to the field of battery manufacturing technology, and specifically relates to an energy storage battery box. Background Technology

[0002] In energy storage battery boxes, batteries are usually first grouped into modules or packs before being placed inside the battery box. This structure causes the battery module or pack structure to occupy too much internal space of the box, resulting in a decrease in the energy density of the energy storage battery box.

[0003] To overcome the above problems, the current common practice is to directly put the battery into the box. However, the lack of limiting and fixing after the battery is put into the box leads to the risk of battery failure. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide an energy storage battery box that can effectively fix the battery and prevent the battery from short-circuiting due to movement.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An energy storage battery box, comprising:

[0007] Box,

[0008] A battery rack is installed inside the housing;

[0009] A battery is disposed on the battery rack. There are multiple batteries, with at least two batteries connected in series. Each battery includes a terminal post and an explosion-proof valve. Both the terminal post and the explosion-proof valve are disposed facing the side of the housing.

[0010] A limiting member is provided at least on the side of the battery holder facing the terminal post, so as to at least restrict the battery from dislodging from the side of the battery holder facing the terminal post.

[0011] As can be seen from the above technical solutions, the energy storage battery box disclosed in this utility model has a limiting member on the side of the battery rack facing the terminal post. The limiting member can at least restrict the battery from coming out of the side of the battery rack facing the terminal post, thereby effectively fixing the battery and preventing the terminal post from contacting the box or other metal parts due to battery movement and causing a short circuit.

[0021] In view of this, the purpose of this utility model is to provide an energy storage battery box that can effectively fix the battery and prevent the battery from short-circuiting due to movement.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please refer to Figures 1 to 2 The energy storage battery box disclosed in this embodiment of the present invention includes a box body 100, a battery rack 300, a battery 200, and a limiting member 400. The battery rack 300 is disposed inside the box body 100, and the battery 200 is disposed on the battery rack 300. There are multiple batteries 200, and at least two batteries 200 are connected in series. The battery 200 includes a terminal post 201 and an explosion-proof valve. Both the terminal post 201 and the explosion-proof valve are disposed facing the side of the box body 100. The limiting member 400 is disposed at least on the side of the battery rack 300 facing the terminal post 201 to prevent the battery 200 from detaching from the side of the battery rack 300 facing the terminal post 201.

[0024] The energy storage battery box disclosed in this embodiment of the present invention has a limiting member 400 provided on at least the side of the battery rack 300 facing the terminal post 201. The limiting member 400 can at least restrict the battery 200 from coming out of the side of the battery rack 300 facing the terminal post 201, thereby effectively fixing the battery 200 and preventing the battery 200 from short-circuiting due to contact between the terminal post 201 and the box body 100 or other metal parts caused by movement.

[0025] It should be noted that the housing 100 disclosed in this embodiment of the present invention has a rectangular structure, specifically including a bottom surface, a top surface, and a side surface, wherein the side surface is disposed between the bottom surface and the top surface. When the battery 200 is placed on the battery rack 300 inside the housing 100, the limiting member 400 may be provided only on the side of the battery rack 300 facing the terminal post 201, or the limiting member 400 may be provided at other positions. Those skilled in the art need to make the selection according to the specific internal structure of the housing 100.

[0026] It should be noted that the battery 200 disclosed in this embodiment of the present invention includes multiple battery packs. Within the same battery pack, the terminals 201 of any two adjacent batteries 200 are electrically connected through at least one conductive element 500.

[0027] For example, batteries 200 are arranged in multiple rows and columns on battery rack 300. In the same battery pack, in the same column of batteries 200, the positive terminal 201 of the battery 200 in the first layer and the negative terminal 201 of the battery 200 in the second layer are electrically connected by at least one conductive element 500. The positive terminal 201 of the battery 200 in the second layer and the negative terminal 201 of the battery 200 in the third layer are electrically connected by at least one conductive element 500. And so on, all batteries 200 in the battery pack can be connected in series.

[0028] The present invention does not limit the specific structure of the conductive element 500. The conductive element 500 may be a wire, a battery connecting piece, or a terminal block, etc., and those skilled in the art can set it according to actual needs.

[0029] This embodiment of the utility model does not limit the specific connection method between the conductive element 500 and the pole 201. The conductive element 500 and the pole 201 can be welded, screwed, or other connected and placed. As long as the connection method meets the requirements of this utility model, it is within the protection scope of this utility model. Those skilled in the art can choose according to actual needs.

[0030] As one embodiment, the conductive component 500 and the terminal 201 disclosed in this utility model embodiment are welded. This connection method not only achieves a tight connection between the conductive component 500 and the terminal 201, improving the conductivity of the battery 200, but also the welded connection has high strength and can withstand external forces such as vibration and impact that may occur during the use of the battery 200.

[0031] As another embodiment, the conductive element 500 and the pole post 201 disclosed in this utility model embodiment are screwed together. Although this connection method is not as strong as welding, it is convenient for operators to install and disassemble. Moreover, the screw connection has relatively low requirements for the material and shape of the conductive element 500 and the pole post 201, and is suitable for connecting pole posts 201 and conductive elements 500 of various types and specifications.

[0032] This embodiment of the invention does not limit the specific arrangement of the terminal post 201 and the explosion-proof valve. As one embodiment, both the terminal post 201 and the explosion-proof valve are located on the same side of the battery 200, wherein the orthographic projection of the limiting member 400 onto the surface of the terminal post 201 does not overlap with the explosion-proof valve. This structural arrangement not only reduces the complexity of the battery 200 installation process but also avoids interference or damage to the explosion-proof valve caused by the installation of the limiting member 400. Therefore, this arrangement simplifies the manufacturing process of the battery 200 and reduces assembly difficulty.

[0033] In another embodiment, the terminal post 201 and the explosion-proof valve disclosed in this utility model embodiment are respectively disposed on different sides of the battery 200. This arrangement can reduce the risk of heat spread in the event of thermal runaway of the battery 200, facilitate a more uniform distribution of heat on the surface of the battery 200, and improve the heat dissipation effect of the battery 200.

[0034] This utility model embodiment does not limit the specific setting method of the limiting member 400. As one embodiment, the limiting member 400 disclosed in this utility model embodiment is a strip structure. The limiting member 400 can be fixed to the end of the battery rack 300 in a direction perpendicular to the bottom surface of the box 100. Since the batteries 200 are stacked in multiple columns and rows in the battery rack 300, the limiting method can specifically be to set at least one limiting member 400 on each column of batteries 200 to limit each column of batteries 200 respectively.

[0035] As another embodiment of this utility model, the limiting member 400 disclosed in this embodiment can also be fixed to the end of the battery rack 300 in a direction parallel to the bottom surface of the housing 100. Similarly, since the batteries 200 are stacked in multiple columns and rows within the battery rack 300, the limiting method can specifically be to provide at least one limiting member 400 on each row of batteries 200 to limit the position of each row of batteries 200.

[0036] Since the limiting member 400 is set horizontally or vertically in the above two fixing methods, the fixing efficiency of the limiting member 400 can be effectively improved.

[0037] In fact, the limit component 400 can also be tilted, but tilting may lead to increased installation difficulty or unstable limiting effect.

[0038] The limiting member 400 disclosed in this embodiment of the utility model can abut against the battery 200, or it can have a certain gap. Both of these configurations have their advantages and disadvantages, and those skilled in the art can choose according to the actual situation.

[0039] When the limiting member 400 comes into contact with the battery 200, it can effectively improve the limiting accuracy. However, the contact pressure of the limiting member 400 may cause wear on the battery casing and may also have a slight impact on the internal structure of the battery 200.

[0040] When there is a certain gap between the limiting member 400 and the battery 200, although it can prevent the battery casing from being worn, scratched or deformed, the limiting effect may not be as good as when the limiting member 400 and the battery 200 are in contact.

[0041] Therefore, when there is a certain gap between the limiting member 400 and the battery 200, the gap ranges from 1mm to 20mm. Specifically, the gap can be 5mm, 10mm or 15mm. This setting can not only improve the limiting effect to a certain extent, but also avoid friction or squeezing caused by direct contact between the limiting member 400 and the battery 200.

[0042] To improve the insulation of the battery 200 and prevent short circuits, an insulating layer is provided between the limiting member 400 and the battery 200 in this embodiment of the invention. The insulating layer can be a plastic film, insulating paper, rubber products, etc., and those skilled in the art can choose according to actual needs.

[0043] This embodiment of the utility model does not limit the positional relationship between the limiting member 400 and the conductive member 500. The orthographic projections of the limiting member 400 and the conductive member 500 on the surface where the pole post 201 is located do not overlap, or the orthographic projections of the limiting member 400 and the conductive member 500 on the surface where the pole post 201 is located at least partially overlap. This embodiment of the utility model does not specifically limit this, and those skilled in the art can choose according to actual needs.

[0044] For example, within the same battery pack, the positive or negative terminals 201 of the upper and lower batteries 200 can be arranged one-to-one, meaning the positive terminal 201 of the upper battery 200 corresponds to the positive terminal 201 of the lower battery 200, and the negative terminal 201 of the upper battery 200 corresponds to the negative terminal 201 of the lower battery 200. In this case, the conductive components 500 are arranged sequentially along a direction perpendicular to the bottom surface of the housing 100. When the limiting member 400 is fixed to the end of the battery rack along a direction perpendicular to the bottom surface of the housing 100, the orthographic projections of the limiting member 400 and the conductive component 500 on the surface of the terminal 201 do not overlap. When the limiting member 400 is fixed to the end of the battery rack along a direction parallel to the bottom surface of the housing 100, the orthographic projections of the limiting member 400 and the conductive component 500 on the surface of the terminal 201 partially overlap.

[0045] In some other specific embodiments, within the same battery pack, the positive or negative terminals 201 of the upper and lower batteries 200 can be staggered. In this case, the conductive element 500 is inclined. When the limiting element 400 is fixed to the end of the battery rack in a direction perpendicular to the bottom surface of the housing 100, or in a direction parallel to the bottom surface of the housing 100, the orthogonal projections of the limiting element 400 and the conductive element 500 on the surface where the terminal 201 is located partially overlap.

[0046] When the orthographic projections of the limiting member 400 and the conductive member 500 on the surface where the pole post 201 is located partially overlap, the limiting effect can be further improved.

[0047] The limiting component 400 can be welded to the battery rack 300, screwed onto the battery rack 300, or fixed to the battery rack 300 by other means.

[0048] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the term "comprising" or any other variation thereof is intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
