[0097] In other words, the battery module 100 according to an exemplary embodiment of the present invention may include a fire extinguishing component 700 disposed in the region between the busbar frame 620 and the battery cell 200, and may be configured to be exposed in the direction facing the battery cell 200.

[0098] The fire extinguishing component 700 may include fire extinguishing material 710 and a capsule 720 configured to contain the fire extinguishing material 710. The fire extinguishing component 700 may include a capsule-shaped fire extinguishing agent containing powdered calcium carbonate or halogen compounds, and may include a material that releases fire extinguishing gases (e.g., carbon dioxide) at high temperatures.

[0099] The fire extinguishing material 710 may be formed from substances such as ammonium phosphate, sodium bicarbonate, potassium bicarbonate, ammonium phosphate, potassium (K)-containing materials, ammonium carbonate, potassium carbonate, magnesium carbonate, or nitrogen, and the invention is not limited thereto. It may also be contained in the form of a solid such as a powder, a liquid, or a gas such as carbon dioxide.

[0100] The containment chamber 720 can be formed from a solid and can be formed to physically break down, melt, or undergo a phase change at a specific temperature or higher.

[0101] The containment chamber 720 can be configured to contain fire extinguishing material 710 and can be located between the busbar frame 620 and the battery cell 200. The fire extinguishing material 710 can be contained inside the containment chamber 720 and can be configured to be discharged to the outside of the containment chamber 720 to extinguish the battery cell 200 in the event of a fire.

[0102] Thus, since the fire extinguishing component 700 is disposed between the busbar frame 620 and the battery cell 200, the battery cell 200 can extinguish the fire in a shorter time compared to a structure in which the fire extinguishing component is disposed between the busbar frame and the sensing cover.

[0103] Meanwhile, the fire extinguishing component 700 can be configured to be fixed to the inner surface 631 of the busbar frame 620 facing the battery cell 200.

[0104] Specifically, the busbar frame 620 may define a recessed retaining groove 632 formed on the inner surface 631. The retaining groove 632 may be configured to extend in a third direction (Z direction or the opposite direction of Z direction). The retaining groove 632 may have a shape that opens from the inner surface 631 in a direction opposite to that of the battery cell 200.

[0105] The containment compartment 720 may include a containment compartment body 730 configured to contain fire extinguishing material 710 and protruding ribs 740 configured to project from the containment compartment body 730 toward the busbar frame 620.

[0106] Inside the main body 730 of the containment chamber, a space can be configured to extend along a third direction (the Z direction or the opposite direction of the Z direction) and accommodate the fire extinguishing material 710. For example... Figure 4 As shown, the space may have a circular cross-section on a cross-section perpendicular to a third direction (Z direction or the opposite direction of Z direction), but the invention is not limited thereto.

[0107] The protruding rib 740 can be configured to protrude from the housing body 730 and can be configured to insert into the fixing slot 632. Like the housing body 730, the protruding rib 740 can be configured to extend in a third direction (Z direction or the opposite direction of Z direction).

[0108] The protruding rib 740 may include an insertion region 741 and a connection region 742. The connection region 742 may include a portion of the protruding rib 740, which may be configured to protrude from the housing body 730 toward the manifold frame 620, and the insertion region 741 may include a portion of the protruding rib 740, which may be configured to extend from the connection region 742 to opposite sides.

[0109] In other words, the protruding rib 740 may include an insertion region 741 and a connecting region 742. The insertion region 741 is configured to be inserted into the fixing slot 632 and blocked by the busbar frame 620. The connecting region 742 is configured to connect the insertion region 741 to the housing body 730 and may have a smaller width than the insertion region 741 in a second direction (the Y direction or the opposite direction of the Y direction).

[0110] The fixing slot 632 may also include an insertion space into which the insertion region 741 is inserted and a connection space into which the connection region 742 is inserted, and the width of the connection space in the second direction (Y direction or the opposite direction of Y direction) may be less than the width of the insertion space in the same direction.

[0111] With this structure, the protruding rib 740 can be configured to be inserted into the fixing slot 632 in a third direction (Z direction or the opposite direction of Z direction), and when the protruding rib 740 is fully inserted into the fixing slot 632, the receiving compartment 720 can be configured to be inserted into the fixing slot 632.

[0112] In this way, when the protruding rib 740 is fully inserted into the fixing slot 632, the housing 720 can be prevented from being removed from the busbar frame 620 in a direction other than the third direction (Z direction), so the fire extinguishing component 700 can be stably fixed in the proper position inside the battery module 100.

[0113] Furthermore, the fire extinguishing component 700 can be disposed between the lead portions 210 of multiple battery cells 200, and can guide the position of the lead portions 210.

[0114] The lead portion 210 can be configured to move along a second direction (the Y direction or the opposite direction of the Y direction), and since the fire extinguishing member 700 is located on opposite sides of the lead portion 210, the movement of the lead portion 210 can be restricted. Accordingly, the electrical connection between the battery cell 200 and the busbar 610 can be stabilized.

[0115] For example, the housing body 730 may have a shape in which its width decreases from the inner surface 631 of the busbar frame 620 toward the battery cell 200 in order to guide the lead portion 210 of the battery cell 200.

[0116] This is because, as the length extending toward the busbar frame 620 increases, the lead portion 210 of the battery cell 200 can be allowed to move freely, but since the end of the lead portion 210 is guided by the housing body 730, the movement of the lead portion 210 can be restricted, thereby stabilizing the electrical connection between the battery cell 200 and the busbar 610.

[0117] Figure 5 A cross-sectional view of the fire extinguishing component and busbar frame of a battery module according to an exemplary embodiment of the present invention is shown.

[0118] Reference Figure 5 According to an exemplary embodiment of the present invention, the fire extinguishing component 700-1 and the manifold frame 620-1 may have the same characteristics as... Figure 4 The fire extinguishing component 700 and the manifold frame 620 shown have different shapes.

[0119] for Figure 5 The description of components other than the structure of the fire extinguishing component 700-1 and the manifold frame 620-1 shown will use... Figures 1 to 4 The description in the text.

[0120] According to an exemplary embodiment of the present invention, a fixing groove 632-1 can be formed in the bus frame 620-1 facing the battery cell 200 (see... Figure 3 The inner surface 631 of the fire extinguishing component 700-1 is concave and can be provided with a pair of fixing grooves 632-1 for a single fire extinguishing component 700-1.

[0121] For example, a pair of fixing slots 632-1 can be provided and configured to be spaced apart from each other in a second direction (the Y direction or the opposite direction to the Y direction). Each of the pair of fixing slots 632-1 may include an insertion space and a connection space. The connection space of the fixing slot 632-1 may include a space extending from the inner surface 631-1, and the insertion space of the fixing slot 632-1 may include a space extending from the connection space toward each other.

[0122] A pair of protruding ribs 740-1 may be provided and configured to be inserted into a pair of fixing slots 632-1 respectively. The pair of protruding ribs 740-1 may be configured to extend symmetrically to each other from opposite ends in a second direction (Y direction or the opposite direction of Y direction) of the receiving compartment body 730-1.

[0123] A pair of protruding ribs 740-1 may include a connecting region 742-1 and an insertion region 741-1. The connecting region 742-1 is configured to extend parallel to the fixing groove 632-1 from opposite ends in a second direction (Y direction or the opposite direction of Y direction) of the receiving chamber body 730-1. The insertion region 741-1 is configured to extend from the connecting region 742-1 in a second direction perpendicular to the extension direction of the connecting region 742-1 and is blocked by the busbar frame 620-1.

[0124] With this structure, a pair of protruding ribs 740-1 can be moved relative to the busbar frame 620-1 only in a third direction (Z direction or the opposite direction of Z direction).

[0125] Accordingly, the protruding rib 740-1 can be configured to be inserted into the fixing slot 632-1 in a third direction (Z direction or the opposite direction of Z direction), so that the receiving compartment 720-1 can be stably fixed in place by the busbar frame 620-1.

[0126] and Figure 4 Similarly, the housing body 730-1 can have a shape in which its width decreases from the inner surface 631 of the busbar frame 620-1 toward the battery cell 200, to guide the lead portion 210 of the battery cell 200. The effect is as follows: Figure 4 As described in [the text].

[0127] Figure 6 A cross-sectional view of the fire extinguishing component and busbar frame of a battery module according to an exemplary embodiment of the present invention is shown.

[0128] Reference Figure 6 According to an exemplary embodiment of the present invention, the fire extinguishing component 700-2 and the manifold frame 620-2 may have the same characteristics as... Figure 4The fire extinguishing component 700 and the manifold frame 620 shown have different shapes.

[0129] for Figure 6 The description of components other than the structure of the fire extinguishing component 700-2 and the manifold frame 620-2 shown will use... Figures 1 to 4 The description in the text.

[0130] According to an exemplary embodiment of the present invention, a fixing groove 632-2 can be formed on the bus frame 620-2 facing the battery cell 200 (see... Figure 3 The inner surface 631 of the ) is concave.

[0131] A protruding rib 740-2 may be provided, and the protruding rib 740-2 may be configured to be inserted into a retaining groove 632-2. In particular, the protruding rib 740-2 may be formed and configured to be inserted into a retaining groove 632-2 and blocked by a busbar frame 620-2.

[0132] For example, the protruding rib 740-2 can have a shape in which its width varies from the fixing groove 632-2 toward the battery cell 200 (see...). Figure 3 The invention is smaller, but it is not limited thereto.

[0133] Accordingly, the protruding rib 740-2 can be configured to be inserted into the fixing slot 632-2 in a third direction (Z direction or the opposite direction of Z direction), so that the housing 720-2 can be stably fixed in place by the busbar frame 620-2.

[0134] and Figure 4 Similarly, the housing body 730-2 can have a shape in which its width decreases from the inner surface 631 of the busbar frame 620-2 toward the battery cell 200, to guide the lead portion 210 of the battery cell 200. The effect is as follows: Figure 4 As described in [the text].

[0135] Figure 7 A cross-sectional view of the fire extinguishing component, adhesive component, and busbar frame of a battery module according to an exemplary embodiment of the present invention is shown.

[0136] Reference Figure 7 According to an exemplary embodiment of the present invention, the fire extinguishing component 700-3 and the manifold frame 620-3 may have the same characteristics as... Figure 4 The fire extinguishing component 700 and the manifold frame 620 shown have different shapes.

[0137] for Figure 7 The description of components other than the structure of the fire extinguishing component 700-3, the adhesive component 800, and the manifold frame 620-3 shown will use... Figures 1 to 4 The description in the text.

[0138] and Figure 4 Unlike other embodiments of the present invention, the manifold frame 620-3 may not be limited to the fixing groove 632. Furthermore, the receiving chamber 720-3 of the fire extinguishing component 700-3 according to an exemplary embodiment of the present invention may not include the protruding rib 740.

[0139] Alternatively, the fire extinguishing component 700-3 can be configured to be attached to the busbar frame 620-3 facing the battery cell 200 via the adhesive component 800 (see...). Figure 3 On the inner surface 631 of the adhesive component 800. The adhesive component 800 may include any material with adhesive properties.

[0140] In other words, with Figure 4 , Figure 5 and Figure 6 In contrast, the fire extinguishing component 700-3 according to an exemplary embodiment of the present invention may not include the structure blocked by the manifold frame 620-3, and may be fixed to the inner surface 631 by the adhesive component 800.

[0141] In other words, the sensing component according to an exemplary embodiment of the present invention may further include an adhesive member 800 configured to fix the fire extinguishing member 700-3 by attaching it to the inner surface 631.

[0142] For example, the fire extinguishing component 700-3 may include fire extinguishing material 710 and a receiving compartment 720-3 configured to contain the fire extinguishing material 710 and to be attached to the inner surface 631 by an adhesive member 800.

[0143] The housing 720-3 can be configured to be stably fixed in place in a third direction (Z direction or the opposite direction of Z direction) by means of adhesive member 800 via busbar frame 620-3.

[0144] The housing 720-3 can have a shape in which its width decreases from the inner surface 631 of the busbar frame 620 toward the battery cell 200, in order to guide the lead portion 210 of the battery cell 200 (see Figure 3 The effect is as follows: Figure 4 As described in [the text].

[0145] Figure 8 A perspective view of a sensing component according to an exemplary embodiment of the present invention is shown. Figure 9 A cross-sectional view of the fire extinguishing component and busbar frame of a battery module according to an exemplary embodiment of the present invention is shown.

[0147] For the description of the sensing component 600-4 according to an exemplary embodiment of the present invention, the following will be used Figure 2 Description of the bus 610 and sensing plate 650 of the sensing component 600 shown.

[0148] Unlike the busbar frame 620, the busbar frame 620-4 can be configured to house fire extinguishing components 700-4 or fire extinguishing material 710 within it.

[0149] The busbar frame 620-4 may include a frame body region 630 extending in a second direction (Y direction or the opposite direction of Y direction) while supporting the busbar 610, and a portion extending from the inner surface 631 of the frame body region 630 toward the plurality of battery cells 200 (see Figure 3 The prominent guiding area 640 is located between the spaces.

[0150] The guiding body region 640 can be configured to guide the lead portion 210 of the battery cell 200. The guiding body region 640 can be configured as a receiving space extending in a third direction (Z direction or the opposite direction of Z direction).

[0151] The extinguishing component 700-4 or the extinguishing material 710 can be configured to be inserted into the receiving space of the guiding body area 640.

[0152] In other words, the fire extinguishing component 700-4 or fire extinguishing material 710 according to an exemplary embodiment of the present invention may have a structure that is accommodated by the guiding body region 640, rather than a structure that is fixed to the inner surface 631.

[0153] The fire extinguishing component 700-4 may include fire extinguishing material 710 and a receiving chamber 720-4 configured to receive the fire extinguishing material 710. The receiving chamber 720-4 may have a cylindrical shape, but the invention is not limited thereto. Furthermore, according to an exemplary embodiment, only the fire extinguishing material 710 itself may be received in the receiving space of the guide body region 640.

[0154] For example, the guiding body region 640 can have a shape in which its width decreases from the inner surface 631 toward the battery cell 200. Figure 4 The principle is the same as that of the main body 730 of the housing, and the main body area 640 can be configured to guide the lead part 210 of the battery cell 200.

[0155] Figure 10 A perspective view of a sensing component according to an exemplary embodiment of the present invention is shown. Figure 11 A cross-sectional view of the fire extinguishing component and busbar frame of a battery module according to an exemplary embodiment of the present invention is shown.

[0157] For the description of the sensing component 600-5 according to another embodiment of the present invention, the following will be used Figure 2 Description of the bus 610 and sensing plate 650 of the sensing component 600 shown.

[0158] Unlike the busbar frame 620, the busbar frame 620-5 can be configured to house fire extinguishing material 710 or fire extinguishing component 700-5 inside it.

[0159] The busbar frame 620-5 may include a frame body region 630 extending in a second direction (Y direction or the opposite direction of Y direction) while supporting the busbar 610, and extending from the inner surface 631 of the frame body region 630 toward the plurality of battery cells 200 (see Figure 3 The space between the main guiding area 640 and the cover area 900 placed on the main guiding area 640.

[0160] The guiding body region 640 can be configured to guide the lead portion 210 of the battery cell 200. The guiding body region 640 can be configured as a receiving space extending in a third direction (Z direction or the opposite direction of Z direction).

[0163] The fire extinguishing component 700-5 may include fire extinguishing material 710 and a receiving chamber 720-4 configured to receive the fire extinguishing material 710. The receiving chamber 720-4 may have a cylindrical shape, but the invention is not limited thereto. Furthermore, only the fire extinguishing material 710 itself may be configured to be received in the receiving space of the guiding body region 640.

[0164] The enclosure area 900 can be configured to be placed on the guiding body area 640 to enclose the containment space. The enclosure area 900 can be fixed to the guiding body area 640 to cover the fire extinguishing component 700-5 or the fire extinguishing material 710 when the battery cell 200 is operating normally, but when a fire occurs in the battery cell 200, the enclosure area 900 can be separated from the guiding body area 640 to guide the fire extinguishing material 710 to be sprayed toward the battery cell 200.

[0165] For example, when a fire occurs in the battery cell 200, the extinguishing material 710, whose temperature has risen, can be configured to expand within the containment space of the guide body region 640 to separate the cover region 900 from the guide body region 640.

[0166] For example, the guiding body region 640 can have a shape in which its width decreases from the inner surface 631 toward the battery cell 200. Figure 4 The principle is the same as that of the main body 730 of the housing, and the main body area 640 can be configured to guide the lead part 210 of the battery cell 200.

[0168] Reference Figure 12 and Figure 13 The sensing component 600-6 may include a busbar 610, a busbar frame 620-6, and a fire extinguishing component 700-6.

[0169] Bus 610 can be configured to be attached to the externally facing surface of bus frame 620-6.

[0170] The bus frame 620-5 may include a frame body region 630 extending along a second direction (Y direction or the opposite direction of Y direction) to support the bus 610, and a frame body region 631 extending from the inner surface 631 of the frame body region 630 toward the plurality of battery cells 200 (see Figure 3 The prominent guiding area 640 is located between the spaces.

[0171] The guiding body region 640 may have a shape in which its width decreases from the inner surface 631 toward the battery cell 200 to guide the lead portion 210 of the battery cell 200. The guiding body region 640 may be configured to define a receiving space extending in a third direction (Z direction or the opposite direction of Z direction).

[0172] The fire extinguishing component 700-6 can be configured to be housed within a receiving space of the guiding body region 640. The outer surface of the fire extinguishing component 700-6 may include portions that are in contact with the guiding body region 640 and portions that are exposed to the battery cell 200.

[0173] A portion of the fire extinguishing component 700-6 may be secured by the guiding body area 640, and another portion may be exposed toward the battery cell 200.

[0174] In other words, the sensing component 600-6 according to an exemplary embodiment of the present invention may include a fire extinguishing component 700-6 disposed in the region between the bus frame 620-6 and the battery cell 200, and may be configured to be exposed in the direction facing the battery cell 200.

[0175] The fire extinguishing component 700-6 may include fire extinguishing material 710 and a containment compartment 720-6 containing fire extinguishing material 710 and disposed on the guiding body area 640 for fixation in place.

[0176] With this structure, when a fire occurs in the battery cell 200, the fire extinguishing component 700-6 can be configured to immediately discharge the fire extinguishing material 710 contained in the containment chamber 720-6 toward the battery cell 200, thereby preventing the battery module 100 (see...) from catching fire.

[0181] The guiding body region 640 may have a shape in which its width decreases from the inner surface 631 toward the battery cell 200 in order to guide the lead portion 210 of the battery cell 200.

[0182] The guiding body region 640 may include a guiding surface 641, which serves as the remaining boundary surface in addition to the inner surface 631. The guiding surface 641 may be the portion of the guiding body region 640 facing the battery cell 200.

[0183] The extinguishing component 700-7 can be configured to be attached to the guiding surface 641. The extinguishing component 700-7 may include an extinguishing agent in the form of powdered calcium carbonate or a halogen compound, and may include a material that releases extinguishing gases (e.g., carbon dioxide) at high temperatures.

[0184] The fire extinguishing material 710 may be formed from substances such as ammonium phosphate, sodium bicarbonate, potassium bicarbonate, ammonium phosphate, potassium (K)-containing materials, ammonium carbonate, potassium carbonate, magnesium carbonate, or nitrogen, and the invention is not limited thereto. It may also be contained in the form of a solid such as a powder, a liquid, or a gas such as carbon dioxide.

[0185] The extinguishing component 700-7 may include a cover plate attached to one surface of the extinguishing material facing the battery cell 200. The cover plate may be formed of a solid and may be shaped to physically break down, melt, or undergo a phase change at a specific temperature or higher.

[0188] When a fire occurs in battery cell 200, fire extinguishing component 700-7 can be configured to immediately extinguish battery cell 200, thereby preventing fire from breaking out of battery module 100 (see...). Figure 1 Heat transfer within the interior.

[0189] Figure 16 A cross-sectional view of a portion of a battery module according to an exemplary embodiment of the present invention is shown.

[0190] Reference Figure 16 The sensing component 600-8 may include a busbar 610, a busbar frame 620-8, a sensing plate 650, and a fire extinguishing component 700-8.

[0191] Bus 610 can be configured to be electrically connected to the lead portion 210 of each of a plurality of battery cells 200.

[0192] Busbar frame 620-8 may include a frame body region 630 extending in a second direction (Y direction or the opposite direction of Y direction) to support busbar 610, and a guide body region 640 protruding from frame body region 630 toward the space between the plurality of battery cells 200.

[0193] The guide body region 640 may have a shape in which its width decreases from the frame body region 630 toward the battery cell 200, so as to guide the lead portion 210 of each of the plurality of battery cells 200.

[0194] The extinguishing component 700-8 may not be in the form of a containment chamber, but may instead be a viscous gel or liquid extinguishing material filling the area between the manifold frame 620-8 and the battery cell 200. For the material of the extinguishing component 700-8, any of the aforementioned extinguishing materials suitable for extinguishing the battery cell 200 may be used.

[0195] The fire extinguishing material 710 may be formed from substances such as ammonium phosphate, sodium bicarbonate, potassium bicarbonate, ammonium phosphate, potassium (K)-containing materials, ammonium carbonate, potassium carbonate, magnesium carbonate, or nitrogen, and the invention is not limited thereto. It may also be contained in the form of a solid such as a powder, a liquid, or a gas such as carbon dioxide.

[0196] By mixing the aforementioned fire extinguishing material 710 with a substrate for gelling, the fire extinguishing component 700-8 can be formed in the form of a gel or a liquid.

[0197] Even with this structure, the sensing component 600-8 may include a fire extinguishing component 700-8, which is disposed in the area between the busbar frame 620-8 and the battery cell 200, and may be configured to be exposed in the direction facing the battery cell 200.

[0198] The fire extinguishing component 700-8 can be exposed toward the battery cell 200; therefore, when a fire occurs in the battery cell 200, the fire extinguishing component 700-8 can be configured to immediately extinguish the battery cell 200, thereby preventing the battery module 100 (see...) from being extinguished. Figure 1 Heat transfer within the interior.

[0199] Figure 17 A cross-sectional view of a portion of a battery module according to an exemplary embodiment of the present invention is shown.

[0200] Reference Figure 17The sensing component 600-9 may include a busbar 610, a busbar frame 620-9, a sensing plate 650, and a fire extinguishing component 700-9.

[0201] Bus 610 can be configured to be electrically connected to the lead portion 210 of each of a plurality of battery cells 200.

[0202] The bus frame 620-9 may include a frame body region 630 extending in a second direction (Y direction or the opposite direction of Y direction) to support the bus 610, and a guide body region 640 protruding from the frame body region 630 toward the space between the plurality of battery cells 200.

[0203] The guide body region 640 may have a shape in which its width decreases from the frame body region 630 toward the battery cell 200, so as to guide the lead portion 210 of each of the plurality of battery cells 200.

[0204] Fire extinguishing component 700-9 may include fire extinguishing material 710 (see...) Figure 4 It can take the form of a housing 720 containing fire extinguishing material 710, and can be located in the area between the guide body area 640 of the busbar frame 620-9 and the battery cell 200.

[0205] In other words, the fire extinguishing component 700-9 can be configured to be inserted and fixed at an appropriate position in the area between the lead portion 210 of each of a pair of adjacent battery cells 200 and the guide body area 640.

[0206] Multiple fire extinguishing components 700-9 can be provided. The housing of each of the multiple fire extinguishing components 700-9 can be formed in various shapes to include one of a circular, rectangular or triangular cross-section in the cross-section perpendicular to a third direction (Z direction or the opposite direction of Z direction).

[0207] The shape of each housing compartment can be appropriately selected to match the shape of the lead section 210 and the guide body area 640.

[0208] Even with this structure, the sensing component 600-9 may include a fire extinguishing component 700-9, which is disposed in the area between the busbar frame 620-9 and the battery cell 200, and may be configured to be exposed in the direction facing the battery cell 200.

[0209] When a fire occurs in battery cell 200, the extinguishing agent of fire extinguishing component 700-9 can be configured to immediately extinguish battery cell 200, thereby preventing fire from breaking out of battery module 100 (see...). Figure 1 Heat transfer within the interior.

[0210] Figure 18A plan view of a battery pack with a battery module applied according to an exemplary embodiment of the present invention is shown. Figure 19 An exemplary embodiment according to the present invention is shown. Figure 18 A schematic diagram of the discharge device for the battery pack shown.

[0211] Reference Figure 18 and Figure 19 The battery pack 1000 may include a battery pack housing 1100 and a plurality of battery modules 100 housed inside the battery pack housing 1100.

[0212] Battery module 100 may include Figures 1 to 17 Any one of the sensing components 600, 600-4, 600-5, 600-6, 600-7, 600-8 and 600-9 shown.

[0213] This structure prevents heat transfer between adjacent battery cells 200 inside the battery module 100. Therefore, it prevents the spread of flames from a burning battery cell 200 to adjacent battery modules 100.

[0214] Therefore, only fluids (e.g., gases or smoke) caused by a fire in the battery cell 200 can be discharged from the battery module 100. For this purpose, a discharge device 1200 for discharging fluids (e.g., air or smoke) can be provided in the battery pack housing 1100 of the battery pack 1000. The discharge device 1200 can be configured to break under a certain pressure or higher.

[0215] Based on the above principle, when the battery cell is 200 (see...) Figure 3 In the event of a fire in the battery pack 1000, fire extinguishing components 700, 700-1, 700-2, 700-3, 700-4, 700-5, 700-6, 700-7, 700-8 or 700-9 can be configured to extinguish the flame, thereby preventing heat transfer between battery cells 200 and preventing thermal runaway within the battery pack 1000, thus enhancing the safety of the battery pack 1000.

[0216] According to this technology, since the fire extinguishing component can be installed between the busbar frame and the battery cell to immediately extinguish the fire in the battery cell, heat transfer to adjacent battery cells inside the battery module can be prevented.

[0217] Furthermore, according to this technology, since the fire extinguishing component guides the lead portion of the battery cell between the busbar frame and the battery cell, the electrical connection between the battery cell and the busbar can be stabilized without any additional structure.

[0218] Furthermore, various effects can be provided directly or indirectly through this invention.

[0219] The above description is merely an example of the technical concept of the present invention, and those skilled in the art can make various modifications and changes without departing from the basic characteristics of the present invention.

[0220] Therefore, the embodiments of the present invention are not intended to limit but rather to explain the technical concept of the invention, and the scope and spirit of the invention are not limited by the above embodiments. The scope of protection of the present invention should be interpreted by the appended claims, and all equivalents thereof should be interpreted as being included within the scope of the present invention.
