Description

Technical Field

[0001] This disclosure relates to a battery transport box and its use for storing and / or transporting battery modules. Background Technology

[0002] This disclosure generally relates to a battery transport box.

[0003] Battery transport boxes are typically configured in a generic way, which makes them unsuitable or inefficient for handling battery modules.

[0004] Battery transport cases typically require modifications to enable more suitable or efficient handling of battery modules. Summary of the Invention

[0005] In one aspect, a battery transport box is disclosed having a storage space for holding one or more battery modules, wherein the storage space is surrounded by a double-walled housing including an outer wall and an inner wall with a gap formed between the outer wall and the inner wall, wherein the inner wall has a plurality of openings connecting the gap and the storage space, and wherein the battery transport box includes one or more absorbent material pads disposed in the gap.

[0006] In another aspect, the use of the battery transport box according to any one of the preceding claims for storing and / or transporting one or more battery modules is disclosed.

[0007] As can be understood from the following discussion, the present invention provides a battery transport box and its use, enabling suitable and efficient handling of battery modules.

[0008] This battery transport case enables the storage and transportation of battery modules, in which any absorbent material used to absorb potential leaks remains securely positioned and can be easily replaced. Leaks from the battery module can still be reliably absorbed through the openings. Furthermore, assembling and disassembling the battery transport case with the absorbent material is easy and requires no specific skills or machinery. Additionally, there is no risk of accidentally emptying the absorbent material when emptying the storage space.

[0009] This application enables the provision of a battery transport box, as seen below, which is also configured to be used as a process box in a battery (module) processing device (such as a black powder production device).

[0010] In the context of automated processing in battery module handling equipment, not only is the storage and transportation of battery modules important, but the transfer of battery modules to specific process steps is also particularly important. This may involve emptying the contents of the battery transport box.

[0011] Automating the process involving the transfer of battery modules is extremely difficult, especially due to the variability of battery modules. Indeed, it is challenging to use existing technologies to move multiple individual battery modules by robot, particularly to remove them from a box.

[0012] Even when battery modules can theoretically be transported centrally, efficiency is low. This battery transport box enables such centralized transport, for example, by tipping the box over. Its configuration allows all battery modules to be emptied while retaining any materials that should not be introduced into subsequent processes, especially absorbent materials. Furthermore, it prevents absorbent material layers from obstructing the passage of battery modules during emptying.

[0013] Accordingly, a configuration that enables the battery transport box to be emptied without accidentally emptying the absorbent material is particularly advantageous, as it enables automated handling of the battery transport box, and in particular, enables the transfer of battery modules to subsequent processes.

[0014] As another effect, retaining the absorbent material when emptying the battery transport box also enables its reuse. If the absorbent material is loosely introduced into the battery transport box, especially in processes aimed at automation, reuse of the absorbent material would be difficult and inefficient.

[0015] In this disclosure, absorption refers to the absorption of liquids, such as leaks from a battery module. That is, absorbent materials can be considered as materials configured to absorb liquids. Absorbent materials can also be called absorbents or absorbent materials.

[0016] In view of the above, a particularly suitable and efficient box for transporting battery modules is provided.

[0017] Specifically, it is necessary to allow liquids (such as electrolyte) leaking from the battery module to reach the absorbent material. The required configuration enables the absorbent material to be placed in a space independent of the storage space, while still allowing liquids to reach the absorbent material from the storage space. As an example, placing the absorbent material in a separate space allows for freer handling of the battery module, because the absorbent material is not affected by the movement of the box and battery module even when the box is emptied by rotating and inverting it. Furthermore, the absorbent material is not at risk of significant displacement within the storage space.

[0018] As required, the absorbent material is placed as a pad, particularly within a double-walled housing, to ensure that the absorbent material remains substantially in place, and especially to maintain a uniform distribution throughout handling, for example, compared to the loss of absorbent material. Because the absorbent material is placed as a pad, the risk of accidental leakage of the absorbent material from the double-walled housing is also lower. For example, with loose absorbent material, it is necessary to allow fluid to reach the absorbent material from the battery module while simultaneously preventing the absorbent material from contacting the battery module; these are conflicting requirements and could lead to leakage of loose absorbent material from its storage location.

[0019] Furthermore, the pad is particularly simple and uncomplicated to handle when it is necessary to remove or place the absorbent material into the battery transport case, especially compared to loose absorbent material.

[0020] The opening can be configured to provide fluid communication between the gap and the storage space.

[0021] According to this disclosure, the outer wall may not have an opening connecting the gap and / or storage space to the outside of the battery transport case. Specifically, according to this disclosure, the battery transport case can be configured such that, in its closed state, there is no fluid connection between the gap and / or storage space and the outside of the battery transport case. Therefore, leakage to the outside of the battery transport case can be ensured.

[0022] According to one aspect of this disclosure, one or more absorbent pads may be made of fabrics such as nonwoven fabrics or of pressed materials.

[0023] This type of absorbent pad is reliable, has good absorption quality, and remains easy to handle. Furthermore, this type of absorbent pad maintains good integrity, and its components have a low risk of detaching from the gaps towards the storage space.

[0024] For example, according to this disclosure, one or more pads may include glass wool.

[0025] According to this disclosure, one or more pads may be made of mineral-based materials, such as vermiculite-based materials. For example, one or more pads may be made of mineral-based fabrics and, in particular, may be asbestos-free.

[0026] The material can be liquid resistant, or in other words, the material can be configured to maintain its structural integrity when wet.

[0027] The material can be heat-resistant. For example, the material can withstand fire for at least a predetermined period of time, such as 30 minutes.

[0028] The gap can be configured such that one or more pads are supported by the inner and outer walls. As an example, the gap can be configured such that the inner and outer walls provide support for one or more pads from both sides. As an example, the gap can be configured such that the inner and outer walls hold one or more pads in a manner that reduces or completely prevents accidental movement and deformation of the pads. In particular, the gap can be configured such that one or more pads can be wedged in place by the inner and outer walls.

[0029] One or more pads can be arranged and their dimensions can be designed such that the gaps on each side of the battery transport box are filled by the pads in both the width and length directions. Therefore, leaked fluid will be reliably absorbed, and accidental lateral movement of one or more pads can be reduced or prevented.

[0030] According to one aspect of this disclosure, one or more absorbent pads may be made of a non-flammable material. For example, a non-flammable material may include glass wool. Alternatively or additionally, a non-flammable material may include a mineral-based material, such as a vermiculite-based material.

[0031] As an example, non-flammable materials can be selected from those classified as non-flammable based on industry standards (such as DIN 4102-1), for example, materials classified as A1 or A2 according to said standard.

[0032] Battery modules are inherently susceptible to overheating and fire. This risk is particularly high for discarded battery modules that may have been damaged to some extent. Monitoring battery modules during transport is difficult, as is taking action in case of overheating and controlling fires. Consequently, the passive safety provided by using pads made of non-flammable materials is especially advantageous and important, particularly during transport.

[0033] According to one aspect of this disclosure, a battery transport box may include: one or more shelves, each shelf including a first wall and a second wall spaced apart; and one or more absorbent material pads disposed between the first wall and the second wall. In this respect, at least one of the first wall and the second wall may include openings connecting a storage space and a space located between the first wall and the second wall, wherein the one or more pads are disposed.

[0034] The openings can be configured to provide fluid communication between the gap and the storage space. For example, these openings can be configured like openings in an inner wall.

[0035] The shelf can be configured to support the battery module during transport. This configuration itself is advantageous because it allows for the absorption of leaks, as the leaked fluid will be absorbed in situ to some extent, rather than potentially spreading within the storage space and then being absorbed by the absorbent material in the double-walled housing.

[0036] A shelf can also be considered an intermediate layer or intermediate shelf. That is, a shelf can be configured to separate multiple layers of battery modules, each of which has its own (possibly absorbent) intermediate layer / shelf.

[0037] Other options for separating battery module layers include introducing loose separators, such as cardboard dividers between the battery modules. However, attempting to remove such loose separators individually during automated handling can make handling more difficult or inefficient (because such separators are difficult to grasp from between battery modules inside the battery transport box), or they may end up in subsequent processes during centralized emptying of the battery transport box, causing problems for those processes. Furthermore, such loose separators do not provide the same securing method for the battery modules during transport as shelves.

[0038] In one aspect of this disclosure, in its packaged state, the battery transport box may not contain any loose materials other than the battery module, particularly loose dividers, and especially loose cardboard or absorbent material.

[0039] Accordingly, the shelving of this disclosure enables improvements in transportation and automated handling.

[0040] Shelves can be foldable, as seen below, which is particularly advantageous for easy handling. However, even fixed shelves are advantageous for automated handling because they have a more defined shape and position compared to loose dividers.

[0041] The first and second walls, when the battery transport box is arranged according to its intended use, can respectively form the top and bottom sides of the shelf. The wall forming the top side can be called the top wall, and the wall forming the bottom side can be called the bottom wall.

[0042] In the intended use of the battery transport box, one or more battery modules will be placed on top of the shelf and supported by the top wall.

[0043] The opening may be arranged at least in the top wall, and especially only in the top wall, or in other words, the opening may be arranged in the upward-facing wall of the shelf, in the orientation of the battery transport box as intended for its purpose. Therefore, leakage from the battery module placed on the shelf will immediately reach the absorbent material inside the shelf. The bottom wall, or in other words, the downward-facing wall of the shelf, in the orientation of the battery transport box as intended for its purpose, may not have any openings to prevent fluid leakage through the shelf.

[0044] It should be understood that, in the context of a double-walled housing, the features and properties of the absorbent pads described in this disclosure are similarly applicable to absorbent pads for shelves.

[0045] It should be noted that, alternatively or additionally, shelves without a double-walled structure and absorbent material may be installed.

[0046] According to one aspect of this disclosure, the shelf can be a folding shelf, wherein the shelf can be configured to fold up toward the inner wall. In particular, the shelf can be configured to fold up toward the side wall.

[0047] According to one aspect of this disclosure, the shelf can be configured to fold away toward the top opening of the battery transport box.

[0048] According to one aspect of this disclosure, the battery transport case may include a cover, and the shelf may be a folding shelf, wherein the shelf can be configured to fold up toward the cover. The cover may be configured to cover the top opening of the battery transport case in its closed state.

[0049] This makes it easier to stack battery modules inside the battery transport case and easier to unload battery modules from the battery transport case.

[0050] In particular, unloading is crucial. Ideally, battery module unloading would be automated, but battery modules are difficult for robots to handle. Such handling is inefficient at best, and in some cases, even impossible. Folding shelves enable the complete emptying of the box by tipping it over, which can be easily automated.

[0051] Therefore, the contents of the box (such as battery modules) can be freely emptied from the battery container, while also having the advantages of shelves (especially absorbent shelves) as further outlined above.

[0052] For example, folding shelves also enable the use of the advantages of shelves without requiring multiple steps, such as emptying different layers from top to bottom and removing the shelves between those layers.

[0053] According to one aspect of this disclosure, the shelf is configured to fold up so that the shelf is aligned with, and in particular flush with, the corresponding inner wall, especially the side wall to which the shelf is attached.

[0054] According to one aspect of this disclosure, the shelf is configured to fold up to 40° to 90°, particularly 60° to 90°, and especially 80° to 90°.

[0055] For example, a hinge can be used to attach the shelf to the inner wall, enabling the shelf to pivot toward the cover, particularly until the shelf is substantially aligned with, or even flush with, the inner wall to which it is attached, so that the shelf is folded up.

[0056] According to one aspect of this disclosure, the shelf is configured to fold up toward the inner wall of the battery transport box, particularly toward the side wall of the battery transport box, so as to form (particularly with its underside) an external constraint on a central passage extending from the shelf of the battery transport box to the top opening of the transport box.

[0057] As should be understood from the above, the folding shelf enables the entire battery transport box to be emptied automatically in an efficient manner, because the folded shelf does not obstruct the passage of the contents of the battery transport box, and does not prevent the contents from falling out of the battery transport box when it is tipped over.

[0058] In other words, the collapsible shelf can be configured to provide a passageway through which all contents of the battery transport box can be dropped.

[0059] In other words, folding shelves can be configured to prevent contents, especially battery modules, from getting stuck between shelves and / or between shelves and inner walls when the shelves are folded up.

[0060] Given the above, it is also clear that there is no need to remove the shelf separately; the entire battery transport box can be emptied in one step, that is, by tilting the battery transport box.

[0061] According to one aspect of this disclosure, the folding shelf may have a flap configuration that hinges to the edge of the inner wall of the adjacent battery transport box. The shelf, particularly in this respect, may be secured by a fixing device that can be repositioned to achieve shelf height adjustment. For example, the fixing device may include a hinge.

[0062] The fixing device described herein may be part of or correspond to the attachment mechanism described below. For example, the fixing device may interact with a portion of a shelf, and the fixing device and that portion together provide the attachment mechanism.

[0063] According to this disclosure, the battery transport case may include a locking mechanism having an engaged state and an disengaged state, wherein, in the engaged state, the locking mechanism prevents one or more shelves from folding up or pivoting. The locking mechanism may include one or more locking elements, such as bolts and / or latches and / or clamps. Specifically, the locking mechanism is configured to enable the centralized disengagement of all locking elements. The locking mechanism may also be configured as or include part of a hinge, such as a hinge having a snap-fit ​​or latching mechanism.

[0064] This makes it possible to quickly empty the battery transport box.

[0065] As explained above, the battery transport case may include a cover. According to one aspect of this disclosure, the cover may be configured such that: in the closed state of the battery transport case, the shelf is mechanically locked to prevent the shelf from folding up; and in the open state of the battery transport case, the shelf is unlocked to allow the shelf to fold up.

[0066] As an example, the cover can be configured to mechanically press down on the shelf (in which case a locking mechanism may not be necessary), and / or to engage the locking mechanism when closed, and / or to keep the locking mechanism engaged in the closed state, for example, one of the locking mechanisms described above.

[0067] As another example, the cover can be configured to press against the battery module in the closed state. In particular, at least the side of the cover facing the battery module can have abrasion-resistant properties. For example, this side can be made of a silicon-based material.

[0068] According to one aspect of this disclosure, the shelf can be configured to fold up under the influence of the weight and / or weight of the battery module when the top opening and / or the side cover of the battery transport box is facing down.

[0069] For example, the transport box can be configured such that when the battery transport box is tipped over (e.g., along the longitudinal edge), the intermediate shelf opens by folding up, releasing the contents to empty the battery transport box. For example, the contents can be emptied into a black powder production facility. Due to the transport box's configuration, one or more pads remain within the gap between the double walls, and if applicable, also remain in the shelf, and these pads will not fall into the equipment when the battery transport box is tipped over.

[0070] According to this disclosure, one or more shelves can be fixed longitudinally and can be configured as imaging flaps, with one support on the left and one on the right. The fixing device can have a grid configuration, allowing for different heights to be set. This enables the storage and transportation of battery modules of different sizes.

[0071] According to one aspect of this disclosure, the shelf spacing may be adjustable.

[0072] In particular, the battery transport box can be configured to allow for height adjustment of the shelves.

[0073] As an example, some or all of one or more shelves can be repositioned within the battery transport box. For example, a repositionable fixing device can be provided for this purpose.

[0074] Therefore, an example of setting adjustable shelf spacing is to use a fixing device for one or more shelves, which can be moved between different positions.

[0075] Alternatively or additionally, multiple fixing devices may be set, for example, in a grid pattern, to be associated with different shelf positions (especially heights).

[0076] According to one aspect of this disclosure, the shelf spacing can be adjusted without tools.

[0077] According to this disclosure, the shelf may be (particularly tool-free) attachable to and detachable from a fixing device (the shelf is attached to the inner wall via the fixing device). Alternatively or additionally, the fixing device (through which the shelf is attached to the inner wall) may, particularly tool-free, be attached to and detachable from the inner wall, and / or may be configured, particularly tool-free, to lock and unlock in different positions, for example by means of wing screws or by means of a locking mechanism.

[0078] According to one aspect of this disclosure, the shelf can be attached to the inner wall via a tool-free attachment mechanism, particularly via a locking mechanism. Specifically, the shelf can be attached to a fixing device without tools, and the shelf is attached to the inner wall via the fixing device.

[0079] For example, a hinge mechanism can be provided as an attachment mechanism. The fixing device may include a hinge for a folding shelf. The hinge can also serve as a locking connection between the shelf and the fixing device.

[0080] According to one aspect of this disclosure, the shelf spacing can be adjusted without tools by removing at least one shelf and reattaching it to a different location. The mechanisms enabling this have been outlined above.

[0081] As should be understood from the above, battery transport boxes can be used in a very flexible manner because the shelves can be adjusted according to the cargo in a simple, even tool-free, way, allowing for quick adjustments without relying on specialized tools. Properly adjusted shelves improve cargo loading and also ensure the safe storage of goods during transport.

[0082] According to one aspect of this disclosure, the battery transport box can be configured as a processing container, which is configured to enable the delivery of battery modules into a battery module processing device.

[0083] Therefore, the battery transport box can also be used to fill the system, thus serving as a process container. This avoids the need to repackage the battery modules and transfer them from the transport box to containers suitable for delivering them to battery processing equipment.

[0084] According to one aspect of this disclosure, the battery transport case may include a cover, and the battery transport case may be configured such that the cover secures the battery module in place and / or compresses the battery module, particularly so that no additional securing device is required to secure the battery module in place within the storage space.

[0085] Therefore, battery modules can be safely stored during transport without the need for laborious or complex devices to hold them in place, while still allowing for flexible filling of the battery transport box.

[0086] According to one aspect of this disclosure, the external shape of the battery transport box may have a recess and a protrusion, and the battery transport box is configured such that when two or more battery transport boxes, including a first battery transport box and a second battery transport box, are stacked, the recess of the first battery transport box and the protrusion of the second battery transport box engage to limit or prevent relative lateral displacement between the first battery transport box and the second battery transport box.

[0087] Therefore, battery transport cases are particularly suitable for transporting several battery transport cases together, for example, in a stacked arrangement in a transport vehicle, while keeping the battery transport cases in place effortlessly. For example, the cases will not easily slip off the top of the cases they are stacked on.

[0088] Battery transport boxes can be configured with materials and construction that allow multiple, especially three or more, battery transport boxes to be stacked without compromising structural integrity when filled with battery modules.

[0089] The height of the battery transport box according to this disclosure may be between 50 cm and 100 cm, particularly between 60 cm and 90 cm, and particularly between 70 cm and 80 cm.

[0090] According to one aspect of this disclosure, the external shape of the battery transport box may have one or more receiving structures configured to accommodate a forklift arm.

[0091] According to one aspect of this disclosure, the inner and outer walls may be made of plastic or metal (especially aluminum).

[0092] This enables particularly advantageous handling of battery transport boxes, especially when transferring them from transport vehicles to the workstations where battery modules are delivered to battery processing equipment.

[0093] The purpose of a battery transport box for storing and / or transporting one or more battery modules may include placing the battery modules in the battery transport box, particularly on one or more of the aforementioned shelves.

[0094] Applications may optionally include adjusting the position of one or more shelves in order to adjust the shelf spacing.

[0095] The application may optionally include stacking multiple battery transport cases, and in doing so, engaging the aforementioned protrusions and recesses of the battery transport cases.

[0096] Applications may include tipping over the battery transport box, particularly along its longitudinal edges, folding over the shelves to release the contents of the battery transport box, particularly the battery modules.

[0097] Applications may include using a battery box with a folding shelf according to this disclosure, whereby the folding shelf folds up under the weight and / or weight of the battery modules by tilting the battery box, particularly with the top or sides of the cover facing downwards, thus automatically unloading the battery box, particularly emptying it. The contents of the battery transport box (e.g., battery modules) are then released. This can be accomplished using a forklift.

[0098] It should be understood that these steps for unloading / emptying the battery transport case are performed with the cover released, especially removed, and / or, where applicable, actuated to the release mechanism of the shelves to enable folding of these shelves. These steps may not be necessary where there is no mechanism preventing the shelves from folding towards the cover side of the case.

[0099] Applications may include: emptying contents, particularly battery modules, into battery processing equipment, particularly black powder production equipment.

[0100] In other words, the application may optionally include emptying the battery transport box, particularly transferring the battery modules from the battery transport box to a battery handling device, especially by tipping the battery transport box. This can be done after the cover has been removed. For example, as mentioned above, the battery transport box may include a folding shelf, and the folding shelf can be folded up under the influence of gravity when the battery transport box is tipped, thereby releasing the battery modules.

[0101] This application may optionally include using a forklift to move the battery transport box by engaging the forklift arm with the aforementioned receiving structure configured to accommodate the forklift arm.

[0102] Any disclosures, embodiments, features, technical effects, and advantages described in the context of the battery transport box in this disclosure also apply to the use of the battery transport box, and vice versa. The benefits provided by any embodiment and example also apply to all other embodiments and examples, and vice versa.

[0104] In the following sections, the terminology and / or technical fields used herein and / or the scope of this disclosure will be outlined by way of definition and / or examples. Where examples are given, it should be understood that this disclosure is not limited to those examples.

[0105] In this disclosure, the term "battery module" should be understood broadly and can refer to, for example, an assembly of battery cells or a pack of battery cells. The battery cells in a battery module may be fixed relative to each other, particularly arranged within a housing or casing. A battery module may include multiple battery cells with electrical contacts. A battery module may include only battery cells of the same type, or it may include at least two different types of battery cells.

[0115] Figure 2c The illustration is a schematic, non-scaled cross-sectional view of a second exemplary battery transport box according to this disclosure. Detailed Implementation

[0116] The following embodiments are merely examples for implementing the methods, systems, or application devices disclosed herein and should not be considered limiting.

[0117] Figures 1a to 1d The illustration shows a first example of a battery transport case 1 according to this disclosure. The battery transport case may be made of, for example, plastic or metal (such as aluminum).

[0118] The battery transport case has a storage space 2 for securing one or more battery modules. The storage space is enclosed by a double-walled housing 3, which includes an outer wall 4 and an inner wall 5, with a gap 6 formed between the outer wall and the inner wall.

[0119] The inner wall 5 has multiple openings 5a, which connect the gap and the storage space.

[0120] In this example, the inner wall 5 is configured as a mesh panel or grid. However, other configurations are conceivable, such as those shown in [example missing]. Figures 2a to 2c As shown in the background.

[0121] One or more absorbent material pads 7 are arranged in the gap.

[0122] The opening provides a fluid connection between the gap and the storage space, allowing liquids leaking from the battery (such as leaked electrolyte) to easily reach the absorbent material. This ensures reliable absorption.

[0123] The battery transport box is shown as including optional shelves 8, each shelf comprising: a first wall 9, referred to in this example as the top wall as it forms the upper side of the shelf; and a second wall 10, referred to in this example as the bottom wall as it forms the lower side of the shelf. The first and second walls are spaced apart. One or more absorbent material pads 11 are arranged between the first and second walls. In the present case, only the first (upper) wall includes openings connecting the storage space and the space 12 located between the first and second walls, in which one or more pads 11 are arranged. Alternatively, the second wall may also include openings connecting the storage space and the space between the first and second walls. However, this configuration is optional and can be omitted or modified.

[0124] Specifically, the shelf may not include absorbent material. The shelf may also not include two walls with a space between them. For example, the shelf may be configured as a panel with or without openings, or as a grille.

[0125] Figures 1a to 1d The shelf shown is a folding shelf, wherein the shelf is configured to fold up toward the cover. For this purpose, the shelf is hinged around its respective edge where it is attached to the inner wall. However, this configuration is optional and can be omitted or modified.

[0126] The battery transport box can provide adjustable shelf spacing, for example by providing attachment mechanism 14 (including fixing device 14a), which enables the shelves to be fixed at different heights within the storage space. However, this configuration is optional and can be omitted or modified.

[0127] exist Figures 1a to 1d In the example shown, the attachment mechanism (particularly the fixing device) may include one or more pairs of elongated strips 14a-1 arranged vertically on the inner wall, each strip having a hole 14a-2. These strips in a pair may be configured and arranged such that their holes are arranged opposite each other, particularly to allow the shelf to be suspended horizontally. For example, the shelf may include pins configured to engage with the holes so that the shelf can be pivotally suspended. At least one of these pins may be a spring pin. The spring pin allows the pin to be quickly and easily engaged and disengaged from the hole. Accordingly, the shelf can be quickly set to different heights by disengaging the pin from a pair of holes arranged at a first height and engaging the pin with a pair of holes arranged at different heights.

[0128] It should be noted that, according to this disclosure, and in particular as described above, the battery transport container can be configured to also be used as a process container, for example, for feeding battery processing equipment (such as black powder processing equipment). However, this configuration is optional and can be omitted or modified.

[0129] exist Figure 1d In the illustration, the battery module 18 is shown located on top of the shelf. However, the battery module is not part of the battery transport box.

[0130] exist Figure 1a and Figure 1b The accompanying figure illustrates a configuration with two pairs of strips. Furthermore, the figure shows two corresponding shelves, each individually attached by a different pair of strips from the two pairs. In this example, the two shelves are configured to be mounted adjacent to each other across the width of the storage space. Specifically, the two shelves can optionally be arranged adjacent to each other across the width of the storage space. The two shelves can be arranged at the same height or different heights within the storage space.

[0131] Alternatively, such as Figure 1c As shown, only a pair of strips can be provided, allowing the shelves to be arranged and attached only in stacking order. As an example, at a given height in the storage space, a shelf can essentially extend across the entire width of the storage space.

[0132] For completeness, it should be noted that the transport container does not require securing devices for the respective free ends of the shelves, and in particular, does not require securing devices for supporting the respective free ends from below. As an example, when the container is filled with battery modules, the battery modules can support the shelf positioned directly above them. However, securing devices may be optionally provided.
