[0036] The following description is used to disclose the present disclosure so that those skilled in the art can implement the present disclosure. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations. The basic principles of the present disclosure defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the present disclosure.

[0037] Those skilled in the art should understand that, in the disclosure of the present invention, the orientation or position relationship indicated by the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0038] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0039] In the present disclosure, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or can communicate with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0040] In the related art, when the battery packs are stored statically, especially when the battery packs are stored statically in multiple layers along the vertical direction, once the battery packs catch fire, the fire will easily spread to other layers along the vertical direction, causing the battery packs in other layers to be burned, thereby causing the fire to expand.

[0041] In view of this, an embodiment of the present disclosure provides a battery pack storage device. When the battery pack storage device of the present disclosure stores the battery packs, even if one layer of the battery packs catches fire, the fire is unlikely to spread to other layers of the battery packs located above or below it, making it difficult for the fire to expand.

[0042] Specifically, Figure 1 It is a schematic structural diagram of a battery pack storage device according to the first embodiment of the present disclosure. Figure 2 yes Figure 1 Cross-sectional view of some components in the Figure 1 and Figure 2 The battery pack storage device of the embodiment of the present disclosure includes a housing 10, a partition layer 20 and a fireproof layer 30. The housing 10 forms a storage cavity 101 and a battery pack inlet and outlet 102 communicating with the storage cavity 101. The partition layer 20 is disposed in the storage cavity 101 and divides the storage cavity 101 into a multi-layer battery pack storage area 1011 arranged in the up-down direction.

[0043] In this way, the battery pack can be loaded into the storage cavity 101 through the battery pack inlet and outlet 102, and be statically stored in the battery pack storage area 1011 between two adjacent partition layers 20, thereby achieving static storage in the battery pack storage area 1011. Since the multiple battery pack storage areas 1011 are arranged vertically, the multiple battery packs stored therein are also statically arranged in the vertical direction.

[0044] See also Figure 2 The fireproof layer 30 is coated on the upper surface and / or the lower surface of the partition layer 20. In this way, when a battery pack catches fire and the fire spreads vertically, the fireproof layer 30 can block the fire, making it difficult for the fire to continue to spread vertically, and further making it difficult for the fire to spread to other battery packs located above or below it, making it difficult for the fire to expand.

[0045] In some examples, the fireproof layer 30 is coated on the upper surface of the partition layer 20, or on the lower surface of the partition layer 20. Therefore, when a battery pack catches fire and the fire spreads vertically, the fireproof layer 30 located above the battery pack and coated on a single surface of the partition layer 20 and the fireproof layer 30 located below the battery pack and coated on a single surface of the partition layer 20 can both block the spread of the fire accordingly. Moreover, since only a single layer of the fireproof layer 30 is provided on each layer of the partition layer 20, the fireproof layer 30 requires a small amount of material and has a low cost.

[0046] In other examples, the fireproof layer 30 is coated on the upper and lower surfaces of the partition layer 20. In this way, when the fire spreads in the up and down directions, the fireproof layer 30 can double block the fire and enhance the fireproof effect.

[0047] Optionally, the partition layer 20 can be arranged as a metal partition plate, and the fireproof layer 30 can be a silicate layer, such as an aluminum silicate layer, and the silicate layer is coated on the upper surface of the metal partition plate, or coated on the lower surface of the metal partition plate, or coated on the upper and lower surfaces of the metal partition plate, so that when the battery packs in one layer catch fire, the fire in the layer is blocked from spreading to the battery packs in other layers above or below it, thereby avoiding the expansion of losses.

[0048] Optionally, the fireproof layer 30 is also coated on the inner wall and / or outer wall of the outer shell 10 .

[0049] In some examples, the fireproof layer 30 is also coated on the entire inner wall of the outer shell 10. Thus, for each of the battery pack storage areas 1011, the inner peripheral wall, inner bottom wall and inner top wall of the battery pack storage area 1011 or the inner peripheral wall and inner bottom wall of the battery pack storage area 1011 or the inner peripheral wall and inner top wall of the battery pack storage area 1011 together form a fireproof enclosure, which can effectively prevent the fire in the battery pack storage area 1011 from spreading to the outside, and further reduce the impact on other layers of battery packs and the external environment.

[0050] In some other examples, the fireproof layer 30 is also coated on the entire outer wall of the outer shell 10. Thus, for each of the battery pack storage areas 1011, the outer peripheral wall, inner bottom wall and inner top wall of the battery pack storage area 1011 or the outer peripheral wall and inner bottom wall of the battery pack storage area 1011 or the outer peripheral wall and inner top wall of the battery pack storage area 1011 together form a fireproof enclosure, which can effectively prevent the fire in the battery pack storage area 1011 from spreading to the outside, and further reduce the impact on other layers of battery packs and the external environment.

[0051] In other examples, the fireproof layer 30 is also coated on the entire outer wall and the entire inner wall of the outer shell 10, so that when the above-mentioned fireproof enclosure is formed in the battery pack storage area 1011, the fireproof effect is better.

[0052] Figure 3 yes Figure 1 Schematic diagram of the structure of some components. Figure 1 and Figure 3 The battery pack storage device further includes a carrier 40. The carrier 40 includes at least one layer of carriers 41, and the carriers 41 are arranged on the partition layer 20 and located in the storage cavity 101, and are used to carry the battery pack.

[0053] For example, the carrier 41 may be disposed above the separator 20 to directly carry the battery pack, or disposed below the separator 20 to assist the separator 20 in carrying the battery pack, or disposed on the same layer as the separator 20 to carry the battery pack together with the separator 20. In this way, the battery pack can be well statically carried, and the battery pack has good stability during static storage.

[0054] Optionally, the carrier 41 cooperates with the partition layer 20 to form a top-opened liquid collecting tank 4102. For example, the carrier 41 can be arranged as a carrier frame, the carrier frame forms one or more windows 4101 that penetrate in the up-down direction, and the partition layer 20 is arranged at the lower openings of several of the windows 4101 to close the lower openings of several of the windows 4101, so as to form one or more liquid collecting tanks 4102.

[0055] In this way, when a stored battery pack is damaged and leaks waste liquid, the liquid collecting tank 4102 located below the battery pack can collect the waste liquid to prevent the waste liquid leaked from the damaged battery pack from flowing freely and causing pollution.

[0056] Optionally, the carrier frame 40 further includes a plurality of support columns 42. The plurality of support columns 42 are disposed on the outer periphery of the carrier frame and connected to the carrier frame to support the carrier frame at a predetermined height. Specifically, the plurality of support columns 42 are connected to the carrier frame by welding.

[0057] Optionally, the support frame 40 is made of metal material. In this way, the support frame 40 has good load-bearing performance and stable load-bearing.

[0058] Figure 4 yes Figure 1 Front view of the device. Figure 1 and Figure 4 The battery pack storage device further includes at least one heightening member 50. The heightening member 50 is disposed above the carrier 41 and is used to support the battery pack 900 so that the battery pack 900 is spaced apart in the vertical direction. The heightening member 50 is disposed above the carrier 41 so that the gap between the battery pack 900 and the carrier 41 in the vertical direction forms a battery pack leakage observation area 501.

[0059] That is to say, when the battery pack 900 is damaged and leaks, especially when the bottom of the battery pack 900 leaks due to wear and tear such as transportation friction, a small amount of leaked waste liquid will be retained at the bottom of the battery pack 900 or drip downward from the bottom of the battery pack 900. Since a gap is formed between the battery pack 900 and the carrier 41 in the up and down directions, namely the battery pack leakage observation area 501, it is convenient for workers to observe whether waste liquid is retained at the bottom of the battery pack 900 or whether waste liquid is leaking downward, and it is convenient to timely detect whether the bottom of the battery pack 900 is leaking.

[0060] Optionally, there are multiple heightening members 50, and the multiple heightening members 50 are arranged above the carrier 41 at intervals to carry the battery pack 900. In this way, the area below the bottom of the battery pack 900 that is not opposite to the heightening member 50 can all become the battery pack leakage observation area 501. As a result, the battery pack leakage observation area 501 has a large range and is convenient for observation.

[0061] In a specific example, there are two height-raising members 50 , and the two height-raising members 50 are arranged at intervals on the supporting member 41 of each layer.

[0062] Figure 5 and Figure 6 1 is a structural schematic diagram and a front view of a battery pack storage device according to another embodiment of the present disclosure. Figure 5 and Figure 6 , there are four heightening members 50, and the four heightening members 50 are arranged at intervals on the carrier 41 of each layer. Therefore, according to the length of the battery pack 900 and the stability requirement of the battery pack 900, more than two heightening members 50 can be selected to carry the battery pack 900. At the same time, it can be understood that the number of the heightening members 50 in the embodiment of the present disclosure includes but is not limited to this, and the number of the heightening members 50 and the spacing distance between them can be adjusted according to applicability.

[0063] Optionally, the heightening member 50 is strip-shaped, made of metal material such as carbon steel and hollow inside, and the heightening member 50 is welded to the supporting member 41 , and a plurality of strip-shaped heightening members 50 are arranged on the supporting member 41 at intervals along the length direction of the supporting member 41 .

[0064] According to some embodiments of the present disclosure, see Figure 1 , the battery pack storage device further includes at least one insulating member 60. The insulating member 60 is disposed above the carrier 41 and is used to carry the battery pack 900. Thus, when the battery pack 900 leaks electricity, the insulating member 60, which is in direct contact with the battery pack 900, will not conduct electricity outward, since the insulating member 60 is insulated, thereby avoiding property losses and personal injuries that may be caused by the conduction outward when the battery pack 900 leaks electricity.

[0065] In some examples, the insulating member 60 is disposed above the heightening member 50. Specifically, there are multiple insulating members 60, and the multiple insulating members 60 are disposed one by one on the multiple heightening members 50. Such a configuration has a good insulation effect, and the battery pack 900 and the carrier 41 can be spaced a large distance in the vertical direction, further preventing the electric energy from being conducted through the metal carrier 41.

[0066] In a specific example, there are two insulating members 60 , and the two insulating members 60 are disposed on the two height-increasing members 50 in a one-to-one correspondence.

[0067] In other examples, the insulating member is directly disposed on the carrier to support the battery pack. In this case, the insulating member not only insulates but also serves to increase the height of the battery pack. The insulating member can create a gap between the battery pack and the carrier in the up and down directions, thereby forming a leakage observation area for the battery pack.

[0068] See also Figure 5 and Figure 6 In other examples, there are four insulating members 60, and the four insulating members 60 are disposed one by one on the four heightening members 50. However, it can be understood that the number of the insulating members 60 in the embodiment of the present disclosure includes but is not limited to this, and the number of the insulating members 60 can be adjusted according to the applicability of the number of the heightening members 50.

[0069] Figure 7 Schematic diagram of the structure of the insulating member and the height-increasing member according to the embodiment of the present disclosure. Figure 7 The insulating member 60 can be detachably arranged on the heightening member 50, for example, can be detachably laid on the upper surface of the heightening member 50. In this way, the insulating member 60 is easy to install and disassemble, and is easy to replace.

[0070] Specifically, the battery pack storage device further includes a fastener 70 such as a rivet or a screw. The fastener 70 passes through the insulating member 60 and is fastened and installed in the height-increasing member 50 , thereby achieving a detachable installation between the height-increasing member 50 and the insulating member 60 .

[0071] Figure 8 Schematic diagram of the connection of the electronic components of the embodiment of the present disclosure. Figure 1 and Figure 8The battery pack storage device further includes a monitoring component 81, a controller 82 and an alarm component 83. The monitoring component 81 is disposed in the storage cavity 101 and is used to monitor whether the battery pack is on fire. The controller 82 is connected to the monitoring component 81 and the alarm component 83 respectively, and is used to control the alarm component 83 to alarm when the battery pack is detected to be on fire. In this way, the staff can promptly find out whether the battery pack is on fire and deal with the fire in a timely manner.

[0072] Optionally, the monitoring component 81 includes one or more of a camera 811, a temperature sensor 812, and a smoke sensor 813. Thus, when the camera 811 detects a fire image and / or the temperature sensor 812 detects a temperature higher than a predetermined value and / or the smoke sensor 813 detects a smoke concentration higher than a predetermined value, the controller 82 can determine that the battery pack 900 is on fire based on the above conditions detected, and control the alarm component 83 to give an alarm in time.

[0073] Optionally, the alarm component 83 can be one or more of a sound-controlled alarm 831 (such as a buzzer) or a light-controlled alarm 832 (such as an alarm light), whereby the alarm component 83 can alert relevant personnel by making a sound or controlling the light changes.

[0074] It should be understood by those skilled in the art that the embodiments of the present disclosure described above and shown in the accompanying drawings are only examples and do not limit the present disclosure. The advantages of the present disclosure have been fully and effectively realized.
