Description

TECHNICAL FIELD

[0001] This application is based on and claims priority to Korean Patent Application No. 10-2024-0037140, filed on March 18, 2024, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety by reference.

[0002] The disclosure relates to a battery module and a battery pack and a vehicle including the same, and more particularly, to a battery module capable of preventing the spread of flames, gas, or high-temperature particles and a battery pack and a vehicle including the same. BACKGROUND

[0003] In general, a secondary battery refers to a battery that can be repeatedly charged and discharged, such as a lithium ion battery, a lithium polymer battery, a nickel-cadmium battery, a nickel-hydrogen battery, or a nickel-zinc battery. A battery cell corresponding to the most basic secondary battery can provide an output voltage of about 2.5 V to 4.2 V.

[0004] Recently, as these battery cells are applied to devices requiring a high output voltage and a large charge capacity, such as an electric vehicle or an ESS (energy storage system), a battery module configured by connecting a plurality of battery cells in series, in parallel, or in a series-parallel combination, and a battery pack configured by connecting the battery module in series, in parallel, or in a series-parallel combination are widely used.

[0005] A lithium secondary battery is currently attracting much attention due to its advantages such as a high operating voltage and a significantly high energy density. However, since the lithium secondary battery uses an organic electrolyte, overcharging of the lithium secondary battery can cause overcurrent and overheating, and in a serious case, can cause an explosion or a fire.

[0006] In the case of a conventional battery module, a refractory pad is provided between a battery cell accommodated inside the battery module and an adjacent battery cell, but due to errors in processing or the like, the module case of the battery module does not make close contact with the refractory pad. As a result, a gap is formed between the module case and the refractory pad, and when a thermal event occurs, flames or gas spread to another battery cell provided nearby through the gap.

[0007] If the flames or gas spread to another battery cell or another battery module, a thermal runaway phenomenon can occur, and if the flames leak to the outside due to the thermal runaway phenomenon, there is a problem that an electric vehicle driver can be burned or in a dangerous situation.

[0008] Alternatively, there is a problem that a battery module or a battery pack is damaged or burned due to a flame chain reaction caused by the spread of flames, and thus it can be impossible to secure the stability of the battery module or the battery pack. SUMMARY

[0009] Technical issues

[0010] The purpose of this disclosure is to provide a battery module capable of preventing flames, gases or high-temperature particles generated in one battery cell from spreading to another adjacent battery cell or another battery module, as well as a battery pack and a vehicle including the battery module.

[0011] Furthermore, the purpose of this disclosure is to provide a battery module capable of emitting flames, gases or high-temperature particles in a predetermined direction, as well as a battery pack and a vehicle including the battery module.

[0012] Furthermore, the purpose of this disclosure is to provide a battery module capable of preventing thermal runaway by preventing a fire chain reaction caused by the spread of flame, as well as a battery pack and a vehicle including the battery module.

[0051] Figure 1 This is a schematic overall perspective view showing a battery module according to a first embodiment of the present disclosure. Figure 2 This is a cross-sectional view showing a battery module according to a first embodiment of the present disclosure, wherein the upper module housing is separate from the side module housing. Figure 3 It is shown Figure 2 An enlarged view of part A in the image. Figure 4 This is a cross-sectional view showing a battery module according to a first embodiment of the present disclosure, wherein the upper module housing is connected to the side module housing, and Figure 5 It is shown Figure 4 An enlarged view of part B in the image.

[0052] Reference Figures 1 to 5 According to the embodiments of the present disclosure, the battery module 10 includes a battery cell stack 100, a module housing 200, and a flame suppression pad 300.

[0053] The battery cell stack 100 can be configured to stack multiple battery cells 110. The battery cells 110 can have various structures, and the multiple battery cells 110 can be stacked in various ways.

[0054] The battery cell 110 may have a structure in which multiple unit cells (in each unit cell, a positive plate, a separator, and a negative plate are arranged in sequence) or multiple dual-cell cells (in each dual-cell cell, a positive plate, a separator, a separator, a positive plate, a separator, and a negative plate are arranged in sequence) are stacked according to the battery capacity.

[0055] The battery cell 110 may be equipped with electrode leads. Electrode leads are terminals exposed to the outside and connected to external devices, and may be made of conductive material. Electrode leads may include positive and negative leads.

[0056] Multiple battery cells 110 can be electrically connected via a busbar (not shown). However, the busbar is not shown in the accompanying drawings.

[0057] The battery cell stack 100 may be provided with multiple boxes (not shown) for accommodating battery cells 110. Each box (not shown) may be manufactured by injection molding of plastic, and multiple boxes (not shown) having accommodating portions for accommodating battery cells 110 may be stacked. The box assembly with multiple boxes (not shown) stacked may be provided with connector elements or terminal elements.

[0058] Connector elements may include various types of electrical connection parts or connecting components for connection to, for example, a BMS (Battery Management System, not shown) that can provide data on the voltage or temperature of the battery cell 110.

[0059] Furthermore, the terminal element is the main terminal connected to the battery cell 110, and includes a positive terminal and a negative terminal. The terminal element is equipped with a terminal bolt to allow for external electrical connection. Meanwhile, the battery cell 110 can have various shapes.

[0060] The battery cell stack 100 is housed in the module housing 200. Furthermore, the module housing 200 may include an upper module housing 210, a lower module housing 220, and a side module housing 230.

[0061] The module housing 200 surrounds the battery cell 110, thereby protecting the battery cell 110 from external vibration or impact.

[0062] The module housing 200 may include a mica sheet made of mica, which has both heat insulation and heat resistance properties, to prevent flame leakage. Here, the mica sheet may include not only a flat mica sheet, but also a mixed shape with flat and curved surfaces.

[0063] The module housing 200 can be formed in a shape corresponding to the shape of the battery cell stack 100. For example, if the battery cell stack 100 is formed in a hexahedral shape with a rectangular cross-section, the module housing 200 can also be formed in a corresponding hexahedral shape.

[0064] The module housing 200 can be formed, for example, by bending a metal sheet, thereby allowing the module housing 200 to be manufactured as a single piece. If the module housing 200 is manufactured as a single piece, the joining process can become easy and simple. Alternatively, the module housing 200 can be provided in a separate form and joined by welding or the like. However, the material of the module housing 200 is not limited to metallic materials.

[0065] If the module housing 200 is formed integrally or joined by welding, no adhesive is required. Therefore, even if the temperature inside the battery module 10 rises, the upper module housing 210 will not separate from the side module housing 230, thereby preventing flames, gases, or high-temperature particles from being emitted in an undesirable direction at once.

[0066] The flame suppression pad 300 prevents flames, gases, or high-temperature particles generated from any battery cell 110 from spreading to another battery cell 110. For this purpose, as... Figure 2 and Figure 4 As shown, the flame suppression pad 300 can be disposed between multiple battery cells 110 within the module housing 200. For example, the flame suppression pad 300 can be disposed between four battery cells 110, but is not limited thereto.

[0067] Here, the flame suppression pads 300 can be arranged at equal intervals or at different intervals.

[0068] The flame suppression pad 300 can be made of various materials, and for example, it can be made of a heat-resistant material to prevent the transfer of flames and heat generated from the battery cell 110. For example, the flame suppression pad 300 can be made of a silicon-based material.

[0069] Here, the flame suppression pad 300 can be made of silicone foam. Silicone foam is a foam pad in which pores are formed, and it has high thermal and chemical stability, as well as excellent flame retardancy and insulation. Therefore, if the flame suppression pad 300 is made of silicone foam, it can reliably prevent the spread of flames, gases, or high-temperature particles.

[0070] In addition, the flame suppression pad 300 can also absorb expansion when expansion occurs in the battery cell 110 (the phenomenon of the battery cell 110 being filled with gas).

[0071] Reference Figure 2 and Figure 4 A cutout 400 may be formed at one end of the flame suppression pad 300. Here, the flame suppression pad 300 is divided into a first pad portion 310 and a second pad portion 320 based on the cutout 400, and can be configured such that the first pad portion 310 and the second pad portion 320 (i.e., the two pad portions) are joined together.Figure 2 In the middle, the first pad portion 310 is located to the left of the cut portion 400, and the second pad portion 320 is located to the right of the cut portion 400.

[0072] Furthermore, a cutout 400 may be formed at one end (e.g., the upper end) of the flame suppression pad 300. Here, the first pad portion 310 and the second pad portion 320 may be joined in various ways (e.g., by adhesive), but are not limited thereto.

[0073] Reference Figure 2 and Figure 3 Before the upper module housing 210 is connected to the side module housing 230, the cutout 400 of the flame suppression pad 300 is not unfolded, and the first pad portion 310 and the second pad portion 320 are in contact with each other. However, as Figure 4 and Figure 5 As shown, if the upper module housing 210 is connected to the side module housing 230, the cutout 400 of the flame suppression pad 300 unfolds.

[0074] In other words, if the upper module housing 210 contacts the flame suppression pad 300 and applies pressure to the flame suppression pad 300, the cutout 400 unfolds and the upper end of the flame suppression pad 300 comes into close contact with the upper module housing 210.

[0075] Here, refer to Figure 4 and Figure 5 The flame suppression pad 300 unfolds outwards via the cutout 400. That is, the first pad portion 310 and the second pad portion 320 unfold so that the ends of the first pad portion 310 and the ends of the second pad portion 320 are separated from each other. In other words, referring to... Figure 5 The end of the first pad 310 is extended to face the left, and the end of the second pad 320 is extended to face the right.

[0076] If the flame suppression pad 300 is pressurized by the upper module housing 210, and the first pad portion 310 and the second pad portion 320 are spread outward by means of the cut portion 400 so that the ends of the first pad portion 310 and the ends of the second pad portion 320 are far apart from each other, then one end (e.g., the upper end) of the flame suppression pad 300 can be in close contact with the upper module housing 210.

[0077] If the upper end of the flame suppression pad 300 is in close contact with the upper module housing 210 in this manner, flames, gases or high-temperature particles generated from any battery cell 110 will be blocked by the flame suppression pad 300 and the upper module housing 210.

[0078] In other words, the above configuration can prevent flames, gases or high-temperature particles from spreading to other battery cells 110.

[0079] Meanwhile, the battery pack 20, which will be described later (see...)Figure 13 The module may include a battery pack housing 21, and the battery pack housing 21 may include an upper battery pack housing 22. A space may be formed between the upper battery pack housing 22 and the upper module housing 210.

[0080] Furthermore, flames, gases, or high-temperature particles generated from any battery cell 110 can be discharged in a predetermined direction through the space between the upper battery pack housing 22 and the upper module housing 210.

[0081] Therefore, the battery module 10 according to the present disclosure has the effect of directional exhaust, which can exhaust flames, gases or high-temperature particles in the direction intended by the designer.

[0082] Figure 6 and Figure 7 Examples are given as Figure 5 The process of unfolding the flame suppression pad in the modified implementation method.

[0083] Reference Figure 6 and Figure 7 The first direction adjustment connecting member 500 can be connected to the inner side of the first pad 310 and the second pad 320 to adjust the unfolding direction of the first pad 310 and the second pad 320.

[0084] Here, the first direction adjustment connecting member 500 can be configured in various ways, and can be, for example, various types of sheet material, but is not limited thereto.

[0085] In other words, such as Figure 6 and Figure 7 As shown, if the first directional adjustment connecting member 500 is connected to the inner side of the first pad 310 and the inner side of the second pad 320 respectively, when the flame suppression pad 300 is pressurized by the upper module housing 210, the first directional adjustment connecting member 500 provides a force to suppress the deformation of the first pad 310 and the second pad 320, so that the first pad 310 and the second pad 320 are subjected to more outward force.

[0086] Therefore, as Figure 7 As shown, the first pad portion 310 and the second pad portion 320 extend outwards away from each other.

[0087] Figure 8 This is a cross-sectional view showing a battery module according to a second embodiment of the present disclosure, wherein the upper module housing is connected to the side module housing, and Figure 9 It is shown Figure 8 An enlarged view of part C in the image.

[0088] The second embodiment of this disclosure differs structurally from the first embodiment in that the unfolding directions of the first pad 310 and the second pad 320 are different from those of the first embodiment. However, the features of the first embodiment that are common to the second embodiment will not be described in detail. Furthermore, the features of the second embodiment that are applicable to the first embodiment can also be applied to the first embodiment.

[0089] Reference Figure 8 and Figure 9 The flame suppression pad 300 unfolds through the cutout 400. That is, the ends of the first pad portion 310 and the second pad portion 320 can be configured to unfold in a state of contact with each other (see...). Figure 9 (part a).

[0090] If the flame suppression pad 300 is pressurized by the upper module housing 210, and the ends of the first pad portion 310 and the second pad portion 320 are unfolded in a state of contact with each other by means of the cut portion 400, then one end (e.g., the upper end) of the flame suppression pad 300 can be in close contact with the upper module housing 210.

[0091] If one end of the flame suppression pad 300 is in close contact with the upper module housing 210 in this manner, flames, gases or high-temperature particles generated from any battery cell 110 are blocked by the flame suppression pad 300 and the upper module housing 210.

[0092] Figure 10 and Figure 11 Examples are given as Figure 9 The process of unfolding the flame suppression pad in the modified implementation method.

[0093] Reference Figure 10 and Figure 11 The second direction adjustment connecting member 600 can be connected to the outer side of the first pad 310 and the second pad 320 respectively to adjust the unfolding direction of the first pad 310 and the second pad 320.

[0094] Here, the second-direction adjusting connecting member 600 can be configured in various ways, and can be, for example, various types of sheet material, but is not limited thereto.

[0095] In other words, such as Figure 10 and Figure 11 As shown, if the second directional adjustment connecting member 600 is connected to the outer side of the first pad 310 and the outer side of the second pad 320 respectively, when the flame suppression pad 300 is pressurized by the upper module housing 210, the second directional adjustment connecting member 600 provides a force to suppress the deformation of the first pad 310 and the second pad 320, so that the first pad 310 and the second pad 320 are subjected to more inward force.

[0096] Therefore, the first pad 310 and the second pad 320 can be configured to unfold so that the ends of the first pad 310 and the ends of the second pad 320 come into contact with each other.

[0097] Figure 12 This is an enlarged view showing the upper side of the flame suppression pad in a battery module according to a third embodiment of the present disclosure.

[0098] The third embodiment of this disclosure differs from the first and second embodiments in that the flame suppression pad 300 is made of one pad portion instead of two pad portions. However, features of the first or second embodiment that are common to the third embodiment will not be described in detail. Furthermore, features of the third embodiment that are applicable to the first or second embodiment can also be applied to the first or second embodiment.

[0099] As mentioned above, refer to Figure 12 The flame suppression pad 300 is made of one pad portion instead of two pad portions. However, a cutout 400 is formed at one end (e.g., the upper end) of one pad portion to allow the flame suppression pad 300 to unfold.

[0100] Furthermore, if the upper module housing 210 contacts the flame suppression pad 300 and applies pressure to the flame suppression pad 300, the cutout portion 400 unfolds and the upper end of the flame suppression pad 300 contacts the upper module housing 210. This is the same as the first or second embodiment described above, and will not be described in detail again.

[0101] Figure 13 This is a diagram schematically illustrating the configuration of a battery pack including battery modules according to various embodiments of the present disclosure.

[0102] Reference Figure 13 The battery pack 20 according to the embodiments of the present disclosure may include one or more battery modules 10 according to the embodiments of the present disclosure described above.

[0103] In addition, the battery pack 20 may also include a battery pack housing 21 for housing the battery module 10, and various devices (such as BMS, current sensors and fuses) for controlling the charging and discharging of the cylindrical battery cells 110 included in the battery module 10.

[0104] Figure 14 It is used to illustrate including Figure 13 A picture of a vehicle with a battery pack.

[0105] Reference Figure 14The vehicle 30 according to embodiments of the present disclosure may include one or more battery modules 10 or one or more battery packs 20 according to embodiments of the present disclosure. Here, the battery pack 20 may include one or more battery modules 10 according to embodiments of the present disclosure.

[0106] Here, vehicle 30 includes various vehicles designed to use electricity (such as electric vehicles or hybrid electric vehicles).

[0107] When directional terms (such as up, down, left, and right) are used here for ease of description only, these terms are for ease of interpretation only, and it will be apparent to those skilled in the art that these terms may change depending on the position of the observer or the element.

[0108] This disclosure has been described in detail. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of this disclosure, are given by way of illustration only, as various changes and modifications within the scope of this disclosure will become apparent to those skilled in the art from this detailed description. Therefore, the previously disclosed embodiments should be considered from an interpretative rather than restrictive perspective. In other words, the true scope of the technical concept of this disclosure is shown in the claims, and all differences within the equivalent scope should be interpreted as including in this disclosure.
