[0048] The preferred embodiments of this disclosure will now be described in detail with reference to the accompanying drawings. The configuration of the apparatus or the control method described below are merely illustrative of embodiments of this disclosure and are not intended to limit the scope of this disclosure. Throughout this specification, the reference numerals used interchangeably represent the same components.

[0049] The specific terminology used in this specification is for illustrative purposes only and is not intended to limit the illustrated embodiments.

[0050] Figure 1 This is an example of a battery transport device 1000. Furthermore, Figure 2 This is another example of the battery transport device 1000.

[0051] Reference Figure 1 and Figure 2 The battery transport device 1000 transports battery cells (not shown) during the charge-discharge process in the formation process, thereby allowing them to be introduced into or taken out of the charge-discharge chamber 910 located in the charge-discharge equipment 900. The battery transport device 1000 may also be referred to as a stacker crane.

[0052] In order to carry out the charging and discharging process, the battery transport device 1000 can transport the manufactured battery cells to the target charging and discharging chamber 910, or transport the battery cells after the charging and discharging process is completed to the next process.

[0053] The battery transport device 1000 can be used not only in the charge-discharge process but also in the aging process. That is, the battery transport device 1000 can be used to move the battery cells to a desired aging chamber (not shown) for aging and then transport them to the next process.

[0054] The battery transport device 1000 used in the aging process differs only in size from the battery transport device 1000 used in the charge-discharge process; their operating principles are completely identical.

[0055] Reference Figure 1 and Figure 2 The battery transport device 1000 includes an internally formed receiving space 101 for accommodating battery cells (see reference). Figure 2 The carrier 100 and the first inlet 111 communicating with the receiving space 101 (see reference) Figure 2 ).

[0056] The bracket 100 can form the receiving space 101. The receiving space 101 can accommodate multiple battery cells. The multiple battery cells can be stacked in the receiving space 101 along the height direction of the bracket 100, or along the front-back direction of the bracket 100.

[0057] For stacking along the front-rear direction of the bracket 100, the battery transport device 1000 may further include a tray 190 detachably disposed in the receiving space 101. For transporting multiple battery cells, the tray 190 may internally and detachably secure multiple battery cells.

[0058] Furthermore, in order to stack along the height direction of the bracket 100, the battery transport device 1000 can arrange the tray 190 along the height direction of the bracket 100 in the receiving space 101. The tray 190 is placed in the receiving space 101 by the transfer part 450 described later, and can be placed through the first inlet 111 and the second inlet 112 described later (see reference). Figure 3 It moves along the front-back direction of the bracket 100.

[0059] Reference Figure 1 and Figure 2The bracket 100 may include: a front surface 110, located at the front, including the first inlet 111, and forming the front surface of the bracket 100; a rear surface 170, located behind the bracket 100 and facing the front surface 110, and including the second inlet 112; side surfaces 150, forming the two sides of the bracket 100, and connecting the front surface 110 and the rear surface 170; and an upper surface 130 (see reference). Figure 3 The bracket connects the front surface 110, the rear surface 170, and the side surface 150, forming the upper surface of the bracket 100.

[0060] Similar to the front surface 110 and the rear surface 170 of the bracket, the first inlet 111 and the second inlet 112 can be arranged facing each other. Therefore, the first inlet 111 and the second inlet 112 can communicate with the receiving space 101. Through the first inlet 111, the battery cell can be introduced into or led out of the receiving space 101. Similarly, through the second inlet 112, the battery cell can be introduced into or led out of the receiving space 101.

[0061] On the other hand, the charge / discharge chamber 910 or aging chamber may be stacked in multiple layers using trays 190. Therefore, the battery transport device 1000 may require a moving unit for moving the battery cells to the target charge / discharge chamber 910 or aging chamber, and a moving unit for introducing the battery cells into or out of the charge / discharge chamber 910.

[0062] Reference Figure 1 and Figure 2 The battery transport device 1000 may include: a first traveling part 410 for moving the bracket 100 in a direction parallel to the front surface 110 of the bracket; a second traveling part 430 for moving the bracket 100 in the height direction of the bracket 100; and a transfer part 450 for moving along the front-rear direction of the bracket 100 to introduce or extract the battery cell into the receiving space 101.

[0063] That is, the movement directions of the first traveling unit 410, the second traveling unit 430, and the transfer unit 450 can be different from each other. As an example, if the first traveling unit 410 moves the bracket 100 in a direction parallel to the first inlet 111 or the second inlet 112, then the second traveling unit 430 can move the bracket 100 along the height direction of the bracket 100. In addition, the transfer unit 450 can move the battery cells housed inside the bracket 100 along the front-rear direction of the bracket 100. Thus, the battery transport device 1000 can be moved to any position in three-dimensional space.

[0064] Reference Figure 1 and Figure 2 The battery transport device 1000 may further include a travel guide rail 415 arranged in a direction parallel to the first inlet 111, and the first travel unit 410 may move the bracket 100 along the travel guide rail 415.

[0065] Therefore, the first driving unit 410 may further include: a first driving motor 4101 that generates rotational force; and a first driving wheel 413 that rotates by the rotation of the first driving motor 4101.

[0066] Similarly, the battery transport device 1000 may further include a mast 435 located on the outside of the bracket 100 and extending along the height direction of the bracket 100.

[0067] The second travel unit 430 can move the bracket 100 along the column 435. The second travel unit 430 may further include: a second travel motor 4301 that generates rotational force; a cable 4303 connected to the second travel motor 4301 and supported by the column 435; and a second travel wheel 433 (see reference). Figure 3 The second travel motor 4301 rotates, causing the cable 4303 to be wound or unwound.

[0068] In contrast, the second traveling wheel 433 is configured as a gear, and the cable 4303 can also be in the form of a chain wound around the gear teeth on the outer side of the second traveling wheel 433. That is, regardless of the mechanism used, the second traveling unit 430 can move the bracket 100 along the height direction of the bracket 100 like a hoist.

[0069] The upper limit of movement along the height direction of the bracket 100 can be determined based on the height of the column 435. This can vary depending on the size of the charging / discharging device 900 or the aging device.

[0070] On the other hand, the transfer unit 450 can move along the front-rear direction of the bracket 100 to introduce or remove the battery cell located in the receiving space 101 from the outside. That is, the transfer unit 450 can move the battery cell into or remove it from the receiving space 101 through the first input port 111 or the second input port 112.

[0071] The transfer unit 450 may further include: a transfer motor (not shown) that generates rotational force; and a fork 451 (see reference 451). Figure 3 When the transfer motor rotates, it moves along the front-rear direction of the bracket 100. The transfer unit 450 may further include a transfer guide rail 4501 disposed inside the bracket 100 (see reference). Figure 3 The fork 451 is used to guide the movement of the fork 451. The fork 451 can move the battery cell or tray 190 along the transfer guide 4501 in the front-rear direction of the bracket 100.

[0072] Typically, in order to move multiple cells at once, the fork 451 can move the tray 190 while in contact with the outside of the tray 190.

[0073] If multiple trays 190 are provided along the height direction of the bracket 100 in the receiving space 101, multiple transfer units 450 can also be provided accordingly. In this case, the battery transport device 1000 can simultaneously move the battery cell to two different charging / discharging chambers 910 via the transfer units 450.

[0074] Figure 3 This is an example of a bracket 100 that houses battery cells.

[0075] As previously mentioned, the bracket 100 can accommodate the battery cells in the accommodating space 101, or accommodate a tray 190 in which the battery cells are detachably fixed.

[0076] On the other hand, the battery cells may catch fire during transportation. Due to the characteristics of the battery cells, fires can easily spread, making it important to extinguish fires that occur during transportation or prevent their spread. To extinguish fires occurring in the housing space 101 or prevent their spread to the outside, the battery transport device 1000 includes a fire extinguishing unit 650 located on the upper surface 130 of the bracket, which can spray extinguishing agents towards the housing space 101 in the event of a fire.

[0077] Furthermore, the battery transport device 1000 includes a first blocking membrane 710 for closing the first inlet 111 in the event of a fire (see reference). Figure 5 For the first blocking membrane 710, using Figure 5 This will be explained later.

[0078] Specifically, the battery transport device 1000 may include: a through hole (not shown) formed through the upper surface 130 of the bracket or the side surface 150 of the bracket; and a fire extinguishing section 650 for spraying fire extinguishing agent through the through hole.

[0079] Reference Figure 3 The fire extinguishing unit 650 is configured to spray through the upper surface 130 of the bracket, but this is only an example.

[0080] Reference Figure 3 The front surface 110 of the bracket may include: a front upper panel 1101 located above the first inlet 111; a front lower panel 1103 located below the first inlet 111; and a front side panel 1105 connecting the front upper panel 1101 and the front lower panel 1103.

[0081] Furthermore, regarding the rear surface 170 of the bracket (refer to...) Figure 2 The same applies to the bracket rear surface 170. That is, the bracket rear surface 170 may include: a rear upper panel (not shown), located above the second inlet 112; a rear lower panel (not shown), located below the second inlet 112; and a rear side panel (not shown), located on both sides of the second inlet 112, and connecting the rear upper panel and the front lower panel.

[0082] Figure 4 This is an example of a block diagram related to the control of the battery transport device 1000.

[0083] Reference Figure 2 and Figure 4 The battery transport device 1000 may include a control unit 600 located outside the bracket 100, which controls the movement of the battery transport device 1000 and the fire extinguishing unit 650. However, this is merely an example; the control unit 600 may be located in other positions as long as it can control the movement of the battery transport device 1000 and the fire extinguishing unit 650.

[0084] Furthermore, in order to move the bracket 100, the control unit 600 can control the movement of the first travel unit 410 and the second travel unit 430. That is, the control unit 600 can control the rotation of the first travel motor 4101 and the second travel motor 4301 to control the movement of the bracket 100.

[0085] Furthermore, referring to Figure 3 and Figure 4 In order to introduce the battery cell into the receiving space 101, or to extract the battery cell from the receiving space 101, the control unit 600 can control the transfer unit 450. The transfer unit 450 may include: a transfer motor (not shown) that generates rotational force; and a fork 451 (see reference 450). Figure 5 When the transfer motor rotates, it moves along the front-rear direction of the bracket 100 through the first input port 111 or the second input port 112; and the transfer guide rail 4501 (see reference) Figure 5 The fork 451 is arranged along the front-rear direction of the receiving space 101 to guide the fork 451. The control unit 600 can control the movement of the fork 451 by controlling the rotation of the transfer motor.

[0086] Furthermore, the control unit 600 can control the fire extinguishing unit 650. In the event of a fire in the containment space 101, the control unit 600 can spray fire extinguishing agent into the containment space 101 through the fire extinguishing unit 650.

[0087] Reference Figure 4 and Figure 5 The control unit 600 can control the fire sensing unit 610 that senses a fire in the containment space 101 and the shielding unit 700 that blocks the containment space 101 from the outside when a fire occurs.

[0088] On the other hand, refer to Figure 2 and Figure 4 The control unit 600 is located on the outside of the bracket 100 and can be protected by a box-shaped outer shell. Furthermore, the control unit 600 can control an input / output unit 800 mounted on the outer shell, which receives user input and outputs the status of the battery transport device or the processing results of received commands to the user.

[0089] Figure 5 This is an example of observing the front surface of the bracket 100 with the first blocking membrane 710 closed and the first inlet 111 closed.

[0090] Reference Figure 5 The battery transport device 1000 includes: a first roller 720 located above the first inlet 111 inside the bracket 100 and rotatably disposed; and a first blocking film 710 wound around the first roller 720 and in a screen-like form that opens and closes the first inlet 111 when the first roller 720 rotates.

[0091] Furthermore, the battery transport device 1000 may further include: a second roller (not shown), and a second inlet 112 located inside the bracket 100 (see reference). Figure 3 The upper part of the bracket 100 is rotatably arranged; a second blocking membrane (not shown) is wound around the second roller and is in the form of a screen that opens and closes the second inlet 112 when the second roller rotates; a rear side panel (not shown) is located on both sides of the second inlet 112 along the height direction of the bracket 100 to guide the movement of the second blocking membrane and form at least a portion of the rear surface of the bracket; and a second washer (not shown) is located inside the rear side panel along the height direction of the bracket 100, so as to contact the second blocking membrane when the second blocking membrane closes the second inlet 112, and to expand toward the second blocking membrane in the event of a fire in the receiving space 101.

[0092] Reference Figure 4 and Figure 5 The control unit 600 can control the shielding unit 700 to block the accommodating space 101 from the outside.

[0093] Specifically, refer to Figure 4 and Figure 5 The control unit 600 can close the first inlet 111 by unwinding the first blocking film 710 from the first roller 720 when the fire sensing unit 610 senses a fire in the containing space 101 by sensing smoke or temperature in the containing space 101.

[0094] Similarly, in the event of a fire in the receiving space 101, the control unit 600 can unwind the second blocking film from the second roller to close the second inlet 112. As described above, since the second blocking film, the second roller, and the second washer have the same function and shape as the first blocking film 710, the first roller 720, and the first washer 770, only their positions differ, detailed descriptions are omitted in this specification.

[0095] That is, unless otherwise specified, the description of the first blocking membrane 710, the first roller 720 and the first washer 770 shall also apply to the second blocking membrane, the second roller and the second washer.

[0096] On the other hand, the control unit 600 can determine whether a fire has occurred in the accommodating space 101 through the fire sensing unit 610.

[0097] The fire sensing unit 610 may include a smoke sensing sensor 6101, which is located on the inner side of the accommodating space 101 and is used to sense smoke in the accommodating space 101.

[0098] When smoke is detected in the containment space 101, the control unit 600 can activate the shielding unit 700 and the fire extinguishing unit 650.

[0099] In contrast, the fire sensing unit 610 may include a temperature sensor 6103 for sensing the temperature of the containment space 101. When the temperature sensor 6103 senses that the temperature of the containment space 101 rises above a preset temperature gradient per unit time, or reaches above an allowable temperature, the control unit 600 may activate the shielding unit 700 and the fire extinguishing unit 650.

[0100] In contrast, the fire sensing unit 610 may include a camera 6105 for photographing the housing space 101. Specifically, the camera 6105 can photograph the battery cells housed in the housing space 101. The control unit 600 can determine whether a fire has occurred using the camera 6105. For this purpose, the battery transport device 1000 may also utilize a vision method. Alternatively, the camera 6105 may be an infrared camera 6105.

[0101] Furthermore, the battery transport device 1000 can also combine at least two of the smoke sensor 6101, the temperature sensor 6103, and the camera 6105 to determine the occurrence of a fire in the containment space 101.

[0102] Reference Figure 5 The shielding portion 700 may include a first blocking film 710 that blocks the first inlet 111, a first roller 720 that winds the first blocking film 710, and a rotating support portion 721 that rotatably supports the first roller 720.

[0103] When the battery transport device 1000 is operating normally, the first blocking film 710 is wrapped around the first roller 720, and the first inlet 111 is in an open state.

[0104] If a fire occurs in the battery cell during the transport of the battery cell by the battery transport device 1000, the control unit 600 can unwind the first blocking film 710 from the first roller 720 to close the first input port 111.

[0105] Therefore, the battery transport device 1000 may further include a blocking motor 723 that rotates the first roller 720.

[0106] On the other hand, the area of ​​the first blocking membrane 710 can be larger than the area of ​​the first inlet 111 to close the first inlet 111. More specifically, along the height direction of the bracket 100, the length of the first blocking membrane 710 can be greater than the height of the first inlet 111. Along the left-right direction of the bracket 100, the width of the first blocking membrane 710 can be greater than the width of the first inlet 111.

[0107] On the other hand, the lower front panel portion 1103 may include an insertion groove 1103a, into which one end of the first blocking membrane 710 is inserted when the first blocking membrane 710 closes the first inlet 111. This is to ensure that the first blocking membrane 710 closes the first inlet by guiding the first blocking membrane 710 when it closes the first inlet 111.

[0108] Similarly, the front side panel portion 1105 may further include a guide portion (not shown) that guides the first blocking membrane 710 when it descends. In contrast, the front side panel portion 1105 may further include a guide groove in the form of a groove or hole inserted into both ends of the first blocking membrane 710 along its width direction.

[0109] When the first blocking membrane 710 closes the first inlet 111, the guide portion and / or the guide groove can assist the first blocking membrane 710 to adhere tightly to the first inlet 111. This structure can also be equivalently applied to the rear surface 170 of the bracket where the second blocking membrane is located.

[0110] On the other hand, in addition to the fire extinguishing unit 650 and the shielding unit 700, the battery transport device 1000 may further include other components that protect the bracket 100 from fire.

[0111] As an example, refer to Figure 3 The inner surface of the accommodating space 101 may be coated with a fire-resistant material or a fire-resistant material coating.

[0112] As another example, electrical components (not shown) exposed to the inner side of the accommodating space 101 may include protective covers (not shown) to protect the electrical components from fire.

[0113] As another example, wires (not shown) exposed to the inner surface of the receiving space 101 can be wrapped with a wire-covering material such as heat-resistant tape (not shown) or fire-resistant tape (not shown) to protect the wires from fire. As a specific example, wires connecting the control unit 600 and the transfer unit 450 may further include a portion of the wires exposed in the receiving space 101 that can be wrapped with a fire-resistant covering material.

[0114] On the other hand, the first blocking membrane 710 may be a sheet of heat-resistant or fire-resistant material.

[0115] Furthermore, the first blocking membrane 710 can be a firescreen made of a rollable material.

[0116] That is, the first blocking membrane 710 may be a fireproof roller shutter that closes the first inlet 111 in the event of a fire in the receiving space 101.

[0117] The shape and material of the first blocking membrane 710 as described above will also be applied equally to the second blocking membrane.

[0118] On the other hand, as mentioned above, the battery transport device 1000 includes: a bracket 100, with a first inlet 111 and a second inlet 112 on its front and rear surfaces respectively, and an internal receiving space 101 for receiving battery cells; a first traveling unit 410 for moving the bracket 100 in the left-right direction; a second traveling unit 430 for moving the bracket 100 in the up-down direction; a transfer unit 450 for introducing or extracting the battery cells through the first inlet 111 and the second inlet 112; and a fire extinguishing unit 650 for spraying non-flammable gas or the solid aerosol into the receiving space 101 based on whether the battery cells contained in the receiving space 101 are on fire.

[0119] The front and rear surfaces of the bracket 100 refer to the front surface 110 and the rear surface 170 of the bracket, respectively.

[0120] Reference Figure 5 At least a portion of the fire extinguishing unit 650 may be located on the upper surface 130 of the bracket or on the side 150 of the bracket.

[0121] The fire extinguishing unit 650 may include: a canister 6502 for supplying fire extinguishing agents such as non-flammable gas or solid aerosol; a nozzle 6501 located on the inner side of the receiving space 101 for spraying the fire extinguishing agent stored in the canister 6502 into the receiving space; and a conduit 6503 connecting the canister 6502 and the nozzle 6501.

[0122] Figure 5 This is shown schematically to illustrate the structure and position of the fire extinguishing unit 650. Considering the weight of the canister 6502, it can also be spaced out and located outside the bracket 100. In contrast, as... Figure 3 As shown, the can portion 6502 can be located on one side of the bracket 100. That is, a portion of the can portion 6502 is exposed to the outside of the bracket 100, and another portion of the can portion 6502 can be inserted into the bracket 100 toward the receiving space 101.

[0123] In other words, at least a portion of the can portion 6502 may be located outside the bracket 100.

[0124] That is, in order to spray the extinguishing agent into the receiving space 101 through the inner side of the receiving space 101, at least a portion of the nozzle portion 6501 can be inserted into the inner side of the receiving space 101 and exposed to the receiving space 101.

[0125] The canister 6502 is located outside the bracket 100, and the nozzle 6501 and the canister 6502 can be connected through the pipe 6503. A valve (not shown) is provided on the pipe 6503 or the canister 6502, so that the control unit 600 can control whether the fire extinguishing unit 650 sprays by controlling the valve.

[0126] Furthermore, the pipe portion 6503 can be formed of a flexible material. This is to simplify the size and position of the can portion 6502 and its connection to the nozzle. To connect the pipe portion 6503 between the can portion 6502 and the nozzle portion 6501, the bracket 100 may further include a through hole (not shown) extending through one side of the bracket 100.

[0127] Taking into account the direction in which the extinguishing agent is sprayed, the extinguishing part 650 may be located on at least one of the side of the bracket or the upper surface 130 of the bracket. Alternatively, the through hole may be located on the upper surface 130 of the bracket and / or the side of the bracket 150.

[0128] On the other hand, the extinguishing agent can be sprayed in the form of a solid aerosol or a gas. The extinguishing agent is stored as a solid or liquid in the canister 6502 and can be changed into a solid aerosol or a gas form during spraying.

[0129] Specifically, the extinguishing agent may include a solid aerosol or non-combustible gas that releases potassium radicals upon spraying.

[0130] As an example, the extinguishing agent can work by injecting a solid aerosol containing potassium radicals into the containment space 101 to interrupt the chemical chain reaction of a fire.

[0131] Solid aerosols refer to mixtures of solid particles and gaseous substances with a diameter of 10 micrometers (mm) or less that exert a fire-extinguishing effect. Typically, solid aerosols are stored in the canister 6502 in the form of other mixtures, spontaneously combusting upon injection to generate solid aerosols, which can then be dispersed.

[0132] As another example, the extinguishing agent may include non-combustible gas. Non-combustible gas cannot spontaneously combust and has the property of not burning other substances; it represents a gas unrelated to combustion.

[0133] For example, the non-combustible gas can represent water vapor (H2O), nitrogen (N2O), etc. 2） Inert gases include carbon dioxide (CO2), helium (He), and argon (Ar). On the other hand, chlorofluorocarbons (CFCs), such as Freon gas, are another example of such non-flammable gases.

[0134] Considering the operating temperature of the battery cells housed in the bracket 100 and environmental pollution, preferably, the non-flammable gas can be any one or a combination of nitrogen, argon, helium and carbon dioxide.

[0135] The reason for using the aforementioned solid aerosol or non-flammable gas is not only that it is harmless to the human body, but also that it will not cause equipment damage, such as corrosion. Furthermore, it can prevent pollution caused by the fire extinguishing agent in buildings or equipment utilizing the battery transport device 1000.

[0136] Figure 6 This is an enlarged view of a portion of the cross-section of the bracket 100 as viewed in the C-C' direction.

[0137] Specifically, a partial cross-section of the first blocking membrane 710, the front side panel portion 1105, and the bracket side 150 is shown.

[0138] When a fire occurs in the battery cell housed in the housing space 101, and the fire sensing unit 610 senses this situation, the control unit 600 can unwind the first blocking film 710 from the first roller 720, thereby closing the first inlet 111. This is to prevent internal smoke and flames from escaping, thereby preventing the fire from spreading.

[0139] At this time, if the first blocking membrane 710 fails to seal the first inlet 111, flames, smoke, or hot air occurring in the receiving space 101 may spread to the outside. Therefore, the battery transport device 1000 includes a first washer 770 located inside the front side panel portion 1105 along the height direction of the bracket 100, and in contact with the first blocking membrane 710 when the first blocking membrane 710 closes the first inlet 111, and capable of expanding toward the first blocking membrane 710 in the event of a fire in the receiving space 101.

[0140] The first washer 770 can be located inside the bracket 100. Specifically, the first washer 770 can be located on the front side panel portion 1105.

[0141] The front side panel portion 1105 may further include a flange 1105b, which is formed by bending around the first inlet toward the receiving space 101. The flange 1105b can serve as a guide when the battery cell or tray 190 is introduced into or out of the receiving space 101.

[0142] The front side panel portion 1105 may further include a rib 1105a, which protrudes along the front-rear direction of the bracket 100 on the inner side surface of the front side panel portion 1105.

[0143] The ribs 1105a not only prevent deformation of the front side panel portion 1105, but also provide a position for mounting the first washer 770. That is, multiple ribs 1105a are provided, and the first washer 770 can be located between the ribs 1105a.

[0144] On the other hand, the first gasket 770 can be formed of an expandable material. That is, when the first blocking membrane 710 closes the first inlet 111, a portion of the first blocking membrane 710 will be located behind the front side panel portion 1105. At this time, the first gasket 770 can minimize or prevent the first blocking membrane 710 from being separated from the front side panel portion 1105.

[0145] Therefore, the first gasket 770 can improve the sealing force of the first blocking membrane 710.

[0146] That is, refer to Figure 6 Air or smoke heated by a fire in the containment space 101 may escape between the first blocking membrane 710 and the front side panel portion 1105 in the direction of the arrow. If the first gasket 770 is formed of a material that can expand with increasing temperature, then in the event of a fire in the containment space 101, the first gasket 770 expands due to the heated air in the containment space 101, thus effectively preventing smoke or heated air from escaping from the gap between the first blocking membrane 710 and the front side panel portion 1105.

[0147] Therefore, the first washer 770 may contain a material that expands when heated.

[0148] The first gasket 770 may contain a smoke-blocking material. Furthermore, the first gasket 770 may contain a flame-retardant material.

[0149] The material of the first gasket 770 can also be a mixture of thermally expanding materials, smoke-resistant materials, and flame-retardant materials. Conversely, the material of the first gasket 770 can also possess the thermal expansion, smoke-resistant, and flame-retardant properties entirely from a single material.

[0150] The first washer 770 may also be located inside the upper front panel 1101 or inside the lower front panel 1103.

[0151] Reference Figure 6 The first washer 770 may include: a main body 7704 including a hollow space 7701 formed inside; a protrusion 7702 protruding from the main body 7704 toward the bracket side 150; and a wing 7703 extending obliquely from the main body 7704 toward the receiving space 101.

[0152] The hollow portion 7701 structurally enhances the strength of the first washer 770, improving its structural resistance to external forces. Furthermore, compared to the main body 7704 being filled, the hollow portion 7701 allows the first washer 770 to expand more smoothly.

[0153] When the first gasket 770 expands, the wing 7703 can come into contact with the first barrier membrane 710 (refer to region A). Therefore, the first gasket can minimize or prevent fluid, i.e., smoke or hot air, from leaking from the containment space 101 to the outside.

[0154] The protrusion 7702 allows the first washer 770 to be attached to the inside of the front side panel portion 1105. Through the protrusion 7702, the first washer 770 can be press-fitted between the ribs 1105a.

[0155] On the other hand, the control unit 600 can unwind the second blocking film (not shown) from the second roller (not shown) to close the second inlet (not shown). To ensure tight contact between the second inlet 112 and the second blocking film (not shown), the battery transport device 1000 may include a second gasket on the inner side of the rear side panel (not shown). The description of this is the same as for the first gasket 770. The material of the second gasket is also the same as that of the first gasket 770.

[0156] Figure 7 This is an example of fire extinguishing unit 650 according to this disclosure.

[0157] The fire extinguishing section 650 may be located on at least one of the side 150 of the bracket or the upper surface 130 of the bracket. Specifically, at least a portion of the tank section 6502 may be located on at least one of the side 150 of the bracket or the upper surface 130 of the bracket.

[0158] The reason for spraying extinguishing agent through the fire extinguishing section 650 is not only to effectively extinguish the fire caused by the battery cell, but also to prevent secondary fires that may occur when the first inlet 111 and the second inlet 112 are opened in the future.

[0159] In contrast, the tank portion 6502 can also be located outside the bracket 100. When the bracket 100 moves via the first travel portion 410 or the second travel portion 430, the fire extinguishing portion 650 can move in the same manner as the bracket 100. This is to prevent the distance between the bracket 100 and the fire extinguishing portion 650 from becoming variable, thereby causing the length of the pipe portion 6503 to become unnecessarily longer.

[0160] Specifically, the nozzle portion 6502 (refer to...) Figure 5 It can be located on the upper surface of the receiving space 101 or on one side of the receiving space 101.

[0161] Reference Figure 7 Multiple fire extinguishing units 650 may be provided. This is to uniformly spray the fire extinguishing agent toward the receiving space 101. That is, to prevent the fire extinguishing agent from failing to reach specific parts of the receiving space 101.

[0162] The extinguishing section 650 may include a first extinguishing section 651 that sprays the extinguishing agent from the upper part of the receiving space 101 toward the lower part of the receiving space 101. This is because it is advantageous to spray from a relatively high position in the receiving space 101 in order to spray the extinguishing agent evenly in the event of a fire.

[0163] Furthermore, the fire extinguishing unit 650 may further include a second fire extinguishing unit 652 that sprays the fire extinguishing agent from at least one side of the receiving space 101. The second fire extinguishing unit 652 may spray the fire extinguishing agent from one side of the receiving space 101 towards the other side. Alternatively, the second fire extinguishing unit 652 may spray the fire extinguishing agent from the other side of the receiving space 101 towards the first side. That is, the second fire extinguishing unit 652 may also spray the fire extinguishing agent from both sides of the receiving space 101 towards mutually facing surfaces.

[0164] Multiple fire extinguishing units 650 are provided, and the multiple fire extinguishing units 650 may include the first fire extinguishing unit 651 and the second fire extinguishing unit 652. Therefore, the first fire extinguishing unit 651 and the second fire extinguishing unit 652 may include: tanks 6512 and 6522 for storing fire extinguishing agents; nozzles 6511 and 6521 for spraying the fire extinguishing agents; and pipes 6513 and 6523 for connecting the tanks 6512 and 6522 and the nozzles 6511 and 6521.

[0165] Reference Figure 7 This illustrates that in the first fire extinguishing unit 651, the tank portion 6512, the pipe portion 6513, and the nozzle portion 6511 are all located on the upper surface 130 of the bracket. In contrast, if the nozzle portion 6511 is located on the upper surface of the receiving space 101, the tank portion 6512 is located in another area, and the pipe portion 6513 can connect the tank portion 6512 and the nozzle portion 6511.

[0166] Similarly, refer to Figure 7 This illustrates that in the second fire extinguishing unit 652, the tank portion 6522, the pipe portion 6523, and the nozzle portion 6521 of the second fire extinguishing unit are all located on the upper surface 130 of the bracket. In contrast, if the nozzle portion 6521 of the second fire extinguishing unit is located on the upper surface of the receiving space 101, then the tank portion 6522 of the second fire extinguishing unit is located in another area, and the pipe portion 6523 of the second fire extinguishing unit can connect the tank portion 6522 and the nozzle portion 6521.

[0167] Figure 8 This is another example of fire extinguishing unit 650 according to this disclosure.

[0168] The nozzle portion 6511 of the first fire extinguishing unit can be configured to spray the fire extinguishing agent downward from the upper part of the receiving space 101. The nozzle portion 6521 of the second fire extinguishing unit can be configured to be close to either side of the receiving space 101, thereby enabling the fire extinguishing agent to be sprayed toward the other side.

[0169] Similarly, it is shown that in the first fire extinguishing unit 651, the tank portion 6512, the pipe portion 6513, and the nozzle portion 6511 of the first fire extinguishing unit are all located on the upper surface 130 of the bracket. In contrast, if the nozzle portion 6511 of the first fire extinguishing unit is located on the upper surface of the receiving space 101, then the tank portion 6512 of the first fire extinguishing unit is located in another area, and the pipe portion 6513 of the first fire extinguishing unit can connect the tank portion 6512 and the nozzle portion 6511.

[0170] As previously described, the battery transport device 1000 can be used in either a charge / discharge process or an aging process. The number and arrangement of the fire extinguishing units 650 can vary depending on the process in which the battery transport device 1000 is used. For example, the battery transport device 1000 used in a charge / discharge process may include both a first fire extinguishing unit 651 and a second fire extinguishing unit 652. Conversely, the battery transport device 1000 used in an aging process may include only the first fire extinguishing unit 651. However, unlike the first fire extinguishing unit, the battery transport device 1000 used in an aging process may also include both the first fire extinguishing unit 651 and the second fire extinguishing unit 652.

[0171] Multiple first extinguishing sections 651 and multiple second extinguishing sections 652 can be provided. This is to ensure that the extinguishing agent is sprayed evenly without any blind spots in the containing space 101.

[0172] Figure 9 This is a flowchart illustrating an example of a control method for a battery transport device 1000 according to the present disclosure.

[0173] The control method of the battery transport device 1000 according to this disclosure includes the following steps: sensing whether a fire has occurred in a battery cell housed in the housing space 101 via a fire sensing unit 610 located on the inner side of the housing space 101 (S100); when a fire is detected in the battery cell by the fire sensing unit 610, closing the first inlet 111 and the second inlet 112 (S400); and when a fire is detected in the battery cell by the fire sensing unit 610, spraying the non-combustible gas or the solid aerosol into the housing space 101 by a fire extinguishing unit 650 that supplies the housing space 101 with non-combustible gas or solid aerosol (S700).

[0174] During the transport of battery cells using the battery transport device 1000, the control unit 600 (see reference) Figure 4 The fire sensing unit 610 can detect whether the battery cell housed in the housing space 101 is abnormal.

[0175] When a fire occurs in the battery cell, the control unit 600 can determine whether a fire has occurred in the housing space 101 through the fire sensing unit 610.

[0176] That is, step S100, which uses the fire sensing unit 610 located on the inner side of the housing space 101 to sense whether a fire has occurred in the battery cell housed in the housing space 101, may include the following steps: sensing whether the battery cell is abnormal using the fire sensing unit 610 (S110); and determining whether a fire has occurred based on the information obtained by the fire sensing unit 610 (S130).

[0177] If, based on the information obtained by the fire sensing unit 610, it is determined that no fire has occurred, the control method of this disclosure can continue to execute step S110, which uses the fire sensing unit 610 to sense whether the battery cell is abnormal. Conversely, if, based on the information obtained by the fire sensing unit 610, it is determined that a fire has occurred, the control method of this disclosure can execute step S400, which closes the first input port 111 and the second input port 112.

[0178] That is, the control unit 600 can control the shielding unit 700 to close the first inlet 111 and the second inlet 112. Specifically, the first blocking film 710 and the second blocking film (not shown) are unwound from the first roller 720 and the second roller (not shown), thereby closing the first inlet 111 and the second inlet 112.

[0179] While performing step S400 of closing the first inlet 111 and the second inlet 112, or after performing step S400 of closing the first inlet 111 and the second inlet 112, step S700 of spraying the non-combustible gas or the solid aerosol into the containment space 101 through the fire extinguishing unit 650 can be performed according to the control method of this disclosure.

[0180] Step S700, which involves spraying the non-combustible gas or the solid aerosol into the containment space 101 via the extinguishing section 650, may include the following steps: spraying the first extinguishing section 651 of the extinguishing section 650 from the upper part of the containment space 101 toward the containment space 101 (S710); and spraying the second extinguishing section 652 of the extinguishing section 650 from at least one side of the containment space 101 toward the containment space 101 (S730).

[0181] According to the control method of this disclosure, step S710, which causes the first fire extinguishing unit 651 to spray, and step S730, which causes the second fire extinguishing unit 652 to spray, can be executed simultaneously, or either one can be executed preferentially.

[0182] For example, according to the control method of this disclosure, after executing step S710 of spraying the first fire extinguishing unit 651, step S730 of spraying the second fire extinguishing unit 652 can be executed. For example, when the battery transport device 1000 is used in a charging and discharging process, the control unit 600 can start spraying the first fire extinguishing unit 651 within a preset first spray start time from the time when a fire occurs in the housing space 101 or the time when a fire is sensed, and after the first spray start time has elapsed, start spraying the second fire extinguishing unit 652 after a preset second spray start time has elapsed.

[0183] In contrast, the control method according to this disclosure can also initiate the spraying of a portion of the first extinguishing unit 651 and the second extinguishing unit at the time of fire occurrence or fire detection in the containment space 101, within a preset first spraying start time. After the first spraying start time has elapsed, the remaining portions of the first extinguishing unit 651 and the second extinguishing unit will begin spraying after a preset second spraying start time has elapsed. This is to ensure that the extinguishing agent effectively penetrates between the stacked battery cells contained in the containment space 101.

[0184] The following are various aspects of this disclosure: First aspect: The battery transport device 1000 according to this disclosure may include: a bracket 100, the front surface and the rear surface of which respectively include a first inlet 111 and a second inlet 112, and the interior forming a receiving space 101; a first traveling unit 410 for moving the bracket 100 in the left-right direction; a second traveling unit 430 for moving the bracket 100 in the up-down direction; a transfer unit 450 for introducing and extracting battery cells contained in the receiving space 101 through the first inlet 111 and the second inlet 112; and a fire extinguishing unit 650 for spraying non-flammable gas or solid aerosol into the receiving space 101 based on whether a fire has occurred in the battery cells contained in the receiving space 101.

[0199] Sixteenth aspect: In the fifteenth aspect, a plurality of second fire extinguishing units 650 may begin to spray the non-combustible gas or the solid aerosol within a preset second spray start time after the first spray start time has elapsed.

[0200] Seventeenth aspect: In either the fifteenth or the sixteenth aspect, a plurality of second fire extinguishing units 650 may begin to spray the non-combustible gas or the solid aerosol during the movement of the first traveling unit 410 or the second traveling unit 430.
