Description

Technical Field

[0001] This disclosure relates to a battery rack, an energy storage device, and a container; more particularly, this disclosure relates to a battery rack, an energy storage device, and a container that can be stably secured during transport.

[0002] This application claims priority to Korean Patent Application No. 10-2020-0135384, filed in Korea on October 19, 2020, the disclosure of which is incorporated herein by reference. Background Technology

[0003] Currently commercially available rechargeable batteries include nickel-cadmium batteries, nickel-metal hydride batteries, nickel-zinc batteries, and lithium rechargeable batteries. Among them, compared with nickel-based rechargeable batteries, lithium rechargeable batteries have almost no memory effect and are therefore attracting much attention due to their advantages of free charging and discharging, extremely low self-discharge rate, and high energy density.

[0004] These lithium-ion secondary batteries primarily use lithium oxides and carbon materials as the positive and negative electrode active materials, respectively. A lithium-ion secondary battery includes: an electrode assembly in which positive and negative electrode plates, respectively coated with positive and negative electrode active materials, are arranged such that a separator is located therebetween; and an exterior, i.e., the exterior of the battery bag, which seals and houses the electrode assembly together with the electrolyte.

[0005] Recently, rechargeable batteries have been widely used not only in small devices such as portable electronic devices, but also in medium and large devices such as vehicles or power storage devices. When used in medium and large devices, multiple rechargeable batteries are electrically connected to each other to increase capacity and output. In particular, pouch-type rechargeable batteries are widely used in medium and large devices due to their easy stacking advantage.

[0006] At the same time, with the increasing need for high-capacity structures used as energy storage sources, the demand for battery racks that include multiple secondary batteries connected in series and / or parallel, as well as battery racks that include battery modules and battery management systems (BMS) that house the secondary batteries, is increasing.

[0007] Furthermore, battery racks typically include a metal housing to protect multiple battery modules from external impacts or to house and store them. In addition, with the increasing demand for high-capacity battery racks, the demand for battery racks capable of accommodating multiple heavy-duty battery modules is also increasing.

[0008] However, when transported while being housed in a container, such heavy-duty battery racks are subjected to vibration, shaking, or large tilting during transport, and in particular, it is difficult to keep the battery racks stably fixed in a fixed position against large external impacts, resulting in problems such as deformation or damage to the battery casings. Summary of the Invention

[0009] Technical issues

[0010] This disclosure is designed to solve problems in related technologies, and therefore aims to provide an easy-to-install battery rack, an energy storage device, and a container.

[0011] These and other objects and advantages of this disclosure will be understood from the following detailed description and will become fully apparent from the exemplary embodiments of this disclosure. Moreover, it will be readily understood that the objects and advantages of this disclosure can be achieved by the means and combinations thereof shown in the appended claims.

[0042] Therefore, the description presented herein is merely a preferred example for illustrative purposes and is not intended to limit the scope of this disclosure. It should be understood that other equivalents and modifications can be made thereto without departing from the scope of this disclosure.

[0043] Figure 1This is a schematic perspective view of a battery rack according to an embodiment of the present disclosure. Figure 2 This is a schematic perspective view of a battery holder according to an embodiment of the present disclosure. Furthermore, Figure 3 This is a perspective view schematically illustrating the fixing members of the battery holder according to an embodiment of the present disclosure. For ease of description, the encapsulation material is shown with the image removed. Figure 2 The battery holder shown.

[0044] refer to Figures 1 to 3 According to embodiments of the present disclosure, the battery rack 100 may include: a plurality of battery modules 110; and at least one battery rack housing 120, the at least one battery rack housing 120 accommodating the plurality of battery modules 110.

[0045] Specifically, the plurality of battery modules 110 can be housed within the battery rack housing 120 and arranged vertically. Each battery module 110 may include: a module housing 111; and a plurality of battery cells (not shown), which are disposed within the module housing 111 and stacked in one direction. For example, each battery cell may be a pouch-type battery cell.

[0046] However, the battery cells of the battery module 110 according to this disclosure are not limited to the pouch-type battery cells described above, but may employ various battery cells known at the time of filing of this disclosure.

[0047] Furthermore, the battery housing 120 can accommodate the plurality of battery modules 110 therein. For example, as Figure 2 As shown, the battery rack housing 120 may include a plurality of storage plates 121 for storing a battery module 110. Two of the plurality of storage plates 121 may support the lower left and right sides of the battery module 110 in an upward direction. Moreover, the two storage plates 121 may prevent other battery modules 110 placed below them from moving upward.

[0048] Furthermore, the battery holder housing 120 may include at least two rings 125. Each ring 125 may include an insertion portion 125a, a portion of which is inserted into and secured to a bolt hole H1 formed on the battery holder housing 120. The insertion portion 125a may be threaded into the bolt hole H1. The ring may include a metal with excellent mechanical rigidity. The metal may be, for example, steel or stainless steel. The ring 125 may be passed through a belt 130. The belt 130 may include a chemical fiber, polyester, or polyethylene material.

[0049] For example, such as Figure 1As shown, two or more rings 125 can be provided on the battery rack housing 120. Eight bolt holes can be provided on the battery rack housing 120, into which the rings 125 can be inserted and secured. Each of the two rings 125 can be passed through a belt 130. The two ends of the belt 130 can be secured to the ground G. In this regard, two rings 125 or eye bolts are also provided on the ground G, such that the two ends of the belt 130 can pass through each of the two rings 125 or be tied to the rings.

[0050] Additionally, the battery housing 120 may include an encapsulation material 160 to cover its body. For example, the encapsulation material 160 may be coated on... Figure 1 The outer surface of the battery holder housing 120 of each of the plurality of battery holders 100 shown. Here, the encapsulation material 160 may include a material such as vinyl or a cloth made of synthetic fibers.

[0051] Therefore, according to this configuration, the present disclosure includes a ring 125 located on the battery rack housing 120 and through which the belt 130 passes, so that the battery rack housing 120 can be secured to the ground G. In particular, even when an external impact occurs during transport, the battery rack 100 of the present disclosure can be stably secured to the ground G. Accordingly, the present disclosure can improve safety.

[0052] Figure 2 This is an exploded perspective view schematically showing the fixing member of the battery holder according to an embodiment of the present disclosure.

[0053] Come back for reference Figure 1 and Figure 2 The battery holder 100 described in this disclosure may further include a fixing member 126. The fixing member 126 may include a fixing portion 126a, a ring portion 126b, and a bending portion 126c. The fixing portion 126a may be fixed to the ground G. For example, the fixing portion 126a may have a plate shape extending horizontally to face the ground G. A fixing hole H2 may be formed in the fixing portion 126a, and a bolt B is inserted into the fixing hole H2. A ground hole (not shown) communicating with the fixing hole H2 may be provided in the ground G. By inserting and fixing the bolt B into each of the fixing hole H2 and the ground hole, the fixing portion 126a can be connected to the ground G.

[0054] Furthermore, the ring portion 126b may be annular. A portion of the ring portion 126b may be connected to the fixing portion 126a. For example, the ring portion 126b may be fixed in such a way that the insertion portion 126ba penetrates the fixing portion 126a. The end of the insertion portion 126ba may be connected to the ground G.

[0055] Furthermore, the bending portion 126c may have a structure that is bent at least twice and extends. The bending portion 126c may have a first portion and a second portion, the first portion being bent upwards from the fixing portion 126a, and the second portion being bent again horizontally from the end of the upwardly bent first portion. The bending portion 126c may cover the lower rod 123 (see [reference needed]) provided on the lower part of the battery holder housing 120. Figure 2 For example, such as Figure 1 As shown, when viewed in the F direction, the fixing member may include the fixing member 126 in each of the front, rear, left, and right sides. All fixing members 126 include the ring portion 126b, but are not limited thereto, and some fixing members 126 may not include the ring portion 126b if necessary.

[0056] Furthermore, in related technologies, because the belt 130 can only be fixed to the ground G, there is a limitation: the fixed position of the belt 130 cannot be arbitrarily changed. In contrast, this disclosure has the following advantages: by utilizing the loop 126b of the fixing member 126 in the container or truck, the end of the belt 130 can pass through or be tied and fixed to the desired position, and a more efficient arrangement of the belt 130 can be achieved, thereby increasing the fixing force of the battery rack 100 and maintaining stable fixation.

[0057] Figure 4 This is a schematic perspective view of a battery rack housing according to another embodiment of the present disclosure.

[0058] refer to Figure 4 ,and Figure 1 Compared to the battery holder 100 described in another embodiment of this disclosure, the battery holder 100 may include two more rings 125A. To join one battery holder housing 120 to another, a strap 130 may pass through two additional rings 125A disposed on each battery holder housing 120. For example, as... Figure 4As shown, in a battery rack 100 arranged in a front-rear direction, a strap 130 passes through each of two rear-positioned rings 125A on the upper surface of the battery rack housing 120 located at the front and two rear-positioned rings 125A on the upper surface of the battery rack housing 120 located at the rear, and the upper portions of the battery rack housing 120 can be joined together by the strap 130.

[0059] Therefore, according to this configuration of the present disclosure, in the present disclosure, by using a ring 125A located on the battery rack housing 120, the battery rack housing 120 can be joined to another adjacent battery rack housing 120, and is able to prevent the arrangement of multiple battery rack housings 120 arranged in one direction from being subjected to external impact or external force interference during transport, or to prevent the battery rack housing 120 from being damaged due to collision during transport.

[0060] Come back for reference Figure 1 The battery rack 100 described in this disclosure may further include a support member 140. The lower part of the body of the support member 140 can be fixed to the ground G of the installation site, and the side of the body of the support member 140 can support the side of the battery rack housing 120. The support member 140 may include reinforced plastic or wood material. For example, the support member 140 may have a cuboid shape. The support member 140 can be fixed to the ground G using nails or adhesive.

[0061] Therefore, according to this configuration, the present disclosure further includes a support member 140 to support the battery rack housing 120, thereby effectively restricting the movement of the battery rack 100 in one direction. Accordingly, the battery rack 100 can be effectively prevented from being moved by external forces, thereby reducing the possibility of damage during transportation and greatly improving safety.

[0062] Come back for reference Figure 1 The battery rack 100 described in this disclosure may include two or more battery rack housings 120 arranged in a front-rear direction. Furthermore, the battery rack 100 may include a plurality of straps 130. The straps 130 may cover the front surface of the battery rack housing 120 located opposite each other in the front-rear direction. Moreover, both ends of each strap 130 may be secured to the ground G or the loop 126b of the fixing member 126.

[0063] For example, such as Figure 1As shown, the two ends of the strap 130 can pass through or be tied and secured to a ring 125 disposed on the ground G. The strap 130 can cover the front surface of the battery rack housing 120 located at the opposite front.

[0064] Therefore, according to this configuration of the present disclosure, the strip 130 covers the front and upper surfaces of the battery rack housing 120 located at the front of two or more battery rack housings 120 arranged in the front-rear direction. Accordingly, when the plurality of battery rack housings 120 are stacked and transported simultaneously in the front-rear direction, the battery rack housing 120 located at the front may be pressed forward by the battery rack housing 120 located at the rear, and in this state, the force of forward pressing can be resisted.

[0065] Figure 5 This is a schematic partial perspective view of the lower part of a battery holder according to another embodiment of the present disclosure. Additionally, Figure 6 This is a perspective view schematically showing a stop member of a battery holder according to another embodiment of the present disclosure.

[0066] Again with Figure 2 Together for reference Figure 5 and Figure 6 According to another embodiment of the present disclosure, the battery rack housing 120 of the battery rack 100 may include at least four support portions 124 extending in the vertical direction. Furthermore, according to another embodiment of the present disclosure, the battery rack 100 may further include a stop 150. The stop 150 can join two battery rack housings 120 together. The stop 150 may include a restraint portion 151 that is bent and extends to cover the support portions 124 of each of the two battery rack housings 120.

[0067] More specifically, the stop 150 may further include a horizontal extension 152 and a vertical extension 153. The horizontal extension 152 may have a plate shape extending in the horizontal direction, thereby being fixed to the ground G. The vertical extension 153 may have a shape that bends upward from the end of the horizontal extension 152 along the side of the support portion 124 of the battery rack housing 120.

[0068] Furthermore, the constraint portion 151 can protrude and extend from each of the two ends of the vertical extension 153 toward each support portion 124 of each of the at least two battery rack housings 120. For example, the constraint portion 151 can have a shape in which it protrudes and extends from the front end of the vertical extension 153 to cover the outer surface of the support portion 124 of the battery rack housing 120 located in the front-rear direction. The constraint portion 151 can also have a shape in which it protrudes and extends from the rear end of the vertical extension 153 to cover the outer surface of the support portion 124 of the battery rack housing 120 located in the rear-rear direction.

[0069] Furthermore, the power storage device according to embodiments of this disclosure may include at least one battery rack 100 as described in this disclosure. Moreover, the power storage device according to this disclosure can be implemented in various forms, such as a smart grid system or a charging station.

[0070] Furthermore, the container according to embodiments of this disclosure includes at least one battery rack 100. Moreover, the container can be a cargo container. For example, the container can be a dry container with an internal floor G made of wood, or a refrigerated container with refrigeration equipment, wherein the internal floor G is made of metal and a track structure is formed on the floor G.

[0071] At the same time, although terms such as up, down, left, right, front, and back are used in this specification to indicate directions, it will be apparent to those skilled in the art that these terms are for convenience of description only and may vary depending on the position of the object or the position of the observer.

[0072] As described above, although this disclosure has been described with reference to limited embodiments and drawings, this disclosure is not limited thereto, and various modifications and variations are possible to those skilled in the art to which this disclosure pertains, within the scope of the technical concept of this disclosure and the equivalents of the appended claims.
