Description

Technical Field

[0001] This disclosure relates to a battery pack.

[0002] This application claims priority to Korean Patent Application No. 10-2024-0128911, filed in Korea on September 24, 2024, the disclosure of which is incorporated herein by reference. Background Technology

[0003] With the significant increase in demand for portable electronic products such as smartphones, tablet PCs and smartwatches, and the growing prevalence of electric vehicles, there is active research into batteries installed in these vehicles, especially secondary batteries that allow for repeated charging and discharging.

[0004] Currently, commercially available rechargeable batteries include nickel-cadmium batteries, nickel-metal hydride batteries, nickel-zinc batteries, and lithium rechargeable batteries. Among them, lithium rechargeable batteries have almost no or no memory effect, so they are more popular than nickel-based rechargeable batteries because they have the advantages of being easily rechargeable at any time, having a very low self-discharge rate, and high energy density.

[0005] Lithium-ion secondary batteries mainly consist of lithium-based oxides and carbon materials used as positive and negative electrode active materials, respectively. A lithium-ion secondary battery includes an electrode assembly and a sealed package or battery casing. The electrode assembly includes a positive electrode plate and a negative electrode plate coated with positive and negative electrode active materials, respectively, with a separator inserted between the positive and negative electrode plates. The sealed package or battery casing houses the electrode assembly and an electrolyte solution.

[0006] Generally, based on the shape of the battery casing, lithium secondary batteries can be divided into can-type secondary batteries and pouch-type secondary batteries. In can-type secondary batteries, the electrode assembly is contained in a metal can, while in pouch-type secondary batteries, the electrode assembly is contained in a pouch of aluminum laminate.

[0007] Recently, rechargeable batteries have been widely used in medium and large-sized devices, such as electric vehicles and energy storage systems (ESS) for driving and storing energy, as well as small devices, such as portable electronic devices. Multiple rechargeable batteries can be electrically connected and stored within a module housing to form a battery module. Each rechargeable battery included in a battery module can then be referred to as a battery cell. Furthermore, multiple battery modules can be connected to each other to form a battery pack.

[0008] However, when a battery pack comprises multiple battery modules, and each battery module comprises multiple battery cells, it may be susceptible to thermal cascading effects between battery modules or battery cells. For example, when an event such as thermal runaway occurs within a single battery module, the propagation of thermal runaway to other battery modules or other battery cells must be prevented. If the propagation of thermal runaway between battery modules or battery cells is not properly suppressed, an event occurring in a particular battery module or battery cell may trigger a cascading thermal reaction in other battery modules or other battery cells, potentially causing an explosion or fire or escalating its scale.

[0009] Specifically, when an event such as thermal runaway occurs in a single battery module, gas or flames can be randomly emitted to the outside. If the emission of gas or flames is not properly controlled, it may be emitted towards other battery modules, potentially causing a thermal cascade in those modules. Specifically, module terminals may be located on the front side of the battery module, and components such as module busbars for electrical connection to other battery modules or battery packs may be present. Therefore, if a flame is emitted to the front side of a battery module, the module terminals may be damaged, and an electrical short circuit may occur within the battery pack. Furthermore, since other battery modules may be present on the front side of a particular battery module, if a flame is emitted to the front side of that module, the emitted flame can be directed to other battery modules, easily causing the flame to spread between battery modules.

[0010] If heat transfer between battery modules or battery cells is not properly controlled, a sudden voltage drop may occur within the battery module or battery pack. This could lead to the sudden shutdown of equipment housing the battery module or battery pack, resulting in unexpected damage. For example, if a sudden voltage drop occurs in the battery pack while an electric vehicle is running, there may not be enough time to move the vehicle to a safe location.

[0011] Furthermore, if heat transfer between battery modules or battery cells is not properly controlled, potentially causing a sudden fire or explosion, there is a high probability of injury or death to users. For example, in the event of thermal runaway in an electric vehicle, if a certain amount of time is not allowed before the fire has fully developed, occupants may not be able to escape safely.

[0048] In the following, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. Before the description, it should be understood that the terminology used in the specification and appended claims should not be construed as limited to its general or dictionary meaning, but rather is interpreted based on the principle of allowing the inventor to appropriately define the terminology for the best interpretation, and on the meaning and concepts corresponding to the technical aspects of the present disclosure.

[0049] Therefore, the description presented herein is merely a preferred example for illustrative purposes and is not intended to limit the scope of this disclosure. It should be understood that other equivalents and modifications may be made thereto without departing from the scope of this disclosure.

[0050] Figure 1 This is a diagram showing a battery pack 1000 according to an embodiment of the present disclosure. Figure 2 It is shown Figure 1 Exploded view of some components of the 1000 battery pack. Figure 3 It is shown Figure 2 Exploded view of some components of the 1000 battery pack.

[0051] Reference Figures 1 to 3 The battery pack 1000 according to embodiments of the present disclosure may include a housing 100. The housing 100 may include a base plate 110. The base plate 110 may have a square shape. The base plate 110 may have a flat shape. The base plate 110 may form the exterior of the battery pack 1000. The base plate 110 may provide the internal space of the battery pack 1000.

[0052] The housing 100 may include sidewalls 120. The sidewalls 120 may be mounted, fastened, coupled, secured, or attached to the upper surface of the base plate 110. Four sidewalls 120 may be provided. The sidewalls 120 may be arranged along the perimeter of the base plate 110. The sidewalls 120 may form the appearance of the battery pack 1000. The sidewalls 120 may provide internal space.

[0053] The housing 100 may include a battery pack cover 150. The battery pack cover 150 may have a square plate shape. The battery pack cover 150 may have a flat plate shape. The battery pack cover 150 may form the exterior of the battery pack 1000. The battery pack cover 150 may cover the internal space of the battery pack 1000.

[0054] Battery cell 220 (see) Figure 5 The battery cell 220 can be located inside the housing 100. Multiple battery cells 220 can be configured. In this case, the battery cell 220 can refer to a secondary battery. Specifically, the battery cell 220 can be a pouch-type secondary battery. However, the shape of the battery cell 220 is not limited to a pouch shape, and the battery cell 220 can have various shapes, such as cylindrical or cuboid.

[0055] The vent plate 400 can be located between the battery cell 220 and the battery pack cover 150. The vent plate 400 can have a wrinkled shape. The vent plate 400 can have a wavy shape. The vent plate 400 can be formed by folding a square plate. The vent plate 400 can have unevenness. The vent plate 400 can have multiple ridges 401 and multiple valleys 402. The vent plate 400 can have a shape with alternating ridges 401 and valleys 402.

[0056] An exhaust space VS can be formed between the battery cell 220 and the battery pack cover 150.

[0057] Traditionally, the shape of the battery pack cover 150 may deform when a thermal event occurs in the battery cell 220. When a thermal event occurs in the battery cell 220, the battery pack cover 150 may deform toward the interior space of the housing 100. Due to the deformation of the battery pack cover 150, the space through which the exhaust gas G can be discharged may be narrowed or blocked.

[0058] When a thermal event occurs in battery cell 220, the vent plate 400 can prevent or suppress deformation of battery pack cover 150. By preventing deformation of battery pack cover 150, the venting space for exhaust gas G can be stably ensured. By smoothly venting exhaust gas G, the propagation of thermal events can be suppressed. By suppressing the propagation of thermal events, the thermal safety of battery pack 1000 can be improved.

[0059] When a thermal event occurs in battery cell 220, exhaust gas G and particulate matter F (e.g., combustible particles) can be expelled. The energy of exhaust gas G and particulate matter F can be reduced by colliding with exhaust plate 400. Due to its reduced energy, exhaust gas G can propagate over a wide area. This reduces the thermal energy propagated per unit area. As the energy of particulate matter F decreases, it will sink under the influence of gravity. This can suppress the propagation of particulate matter F and the propagation of the thermal event.

[0060] Reference Figures 1 to 3The battery pack 1000 may include partition walls 300. Partition walls 300 may include a first partition wall 310 and a second partition wall 320. Multiple partition walls 300 may be provided. Partition walls 300 may be mounted, fastened, fixed, connected, or attached to the upper surface of the base plate 110. Partition walls 300 may divide the internal space of the battery pack 1000. The first partition wall 310 may extend in a front-back direction or an X-axis direction. Multiple first partition walls 310 may be provided. Multiple first partition walls 310 may be arranged in a left-right direction or a Y-axis direction. The second partition wall 320 may extend in a left-right direction or a Y-axis direction.

[0061] The battery pack 1000 may include a venting device 500. The venting device 500 may be mounted on a side wall 120. For example, the venting device 500 may be mounted on a right side wall 120. For example, the venting device 500 may be a valve. When the pressure inside the housing 100 increases, the venting device 500 may open to release gas. Furthermore, the venting device 500 may prevent external air from flowing into the housing 100. Multiple venting devices 500 may be provided.

[0062] Figure 4 It is shown Figure 3 The diagram shows the battery module 200. Figure 5 It shows Figure 4 A diagram of some components of the battery module 200. (Refer to...) Figures 1 to 5 The battery pack 1000 may include battery modules 200. Multiple battery modules 200 may be configured. Each battery module 200 may include multiple battery cells 220. The battery modules 200 or battery cells 220 may be located in a space separated by a partition wall 300. A venting space VS may be formed between the battery modules 200 and the battery pack cover 150.

[0063] Traditionally, the shape of the battery pack cover 150 may deform when a thermal event occurs in the battery module 200. Due to this deformation, the venting space VS may become narrowed or blocked.

[0064] When a thermal event occurs in the battery module 200, the vent plate 400 can prevent or suppress deformation of the battery pack cover 150. By preventing deformation of the battery pack cover 150, the venting space VS can be stably ensured. When a thermal event occurs in the battery module 200, the vent plate 400 can prevent or suppress deformation of the battery module 200. By preventing deformation of the battery module 200, the venting space VS can be stably ensured. By smoothly discharging the exhaust gas G, the propagation of the thermal event can be suppressed. By suppressing the propagation of the thermal event, the thermal safety of the battery pack 1000 can be improved.

[0065] When a thermal event occurs in the battery module 200, exhaust gas G and particulate matter F (e.g., combustible particles) can be expelled. The energy of exhaust gas G and particulate matter F can be reduced by colliding with the exhaust plate 400. Due to its reduced energy, exhaust gas G can propagate over a wide area. This reduces the thermal energy propagated per unit area. Due to the reduced energy of particulate matter F, particulate matter F may sink under the influence of gravity. This can suppress the propagation of particulate matter F and the propagation of the thermal event.

[0066] See Figures 1 to 5 The battery module 200 may include a frame 210. The frame 210 may form the appearance of the battery module 200. The battery module 200 may have a cuboid shape. The frame 210 may include a top plate 210a and a lower frame 210b. The frame 210 may provide space therein. The lower frame 210b may include a base plate and a pair of side plates. The top plate 210a may be mounted, fastened, coupled, fixed, or attached to the pair of side plates. For example, the top plate 210a may be welded to the lower frame 210b. The frame 210 may have openings at the front and rear sides.

[0067] The frame 210 may have a second vent 211 in the top plate 210a. The second vent 211 may be formed in the upper surface of the frame 210. The second vent 211 may connect the interior and exterior of the frame 210. In the event of a thermal event, exhaust gas G and particulate matter F (e.g., combustible particles) may be discharged to the exterior of the battery module 200 through the second vent 211.

[0068] The battery module 200 may include battery cells 220. Battery cells 220 may be housed within a frame 210. Multiple battery cells 220 may be stacked in a left-right direction or a Y-axis direction. Each battery cell 220 may include a receiving portion 221 with electrode assemblies, a first sealing portion 222 protruding to the front and rear sides of the receiving portion 221, and a second sealing portion 223 protruding upward from the receiving portion 221. Furthermore, each battery cell 220 may include electrode leads 224 protruding to the front and rear sides of the first sealing portion 222, respectively. Each battery cell 220 may extend in a front-rear direction or a Y-axis direction. The electrode leads 224 may protrude to the front and rear sides of each battery cell 220.

[0069] The pad 250 may be disposed between multiple battery cells 220. The pad 250 may be arranged between at least some of the battery cells 220 and / or around the periphery of the stack. For example, the pad 250 may be configured to be disposed between every four battery cells 220 stacked in a left-right direction.

[0070] The pad 250 may contain an elastic material to allow the battery cell 220 to absorb expansion. For example, the pad 250 may contain a foam material such as polyurethane. Alternatively, the pad 250 may contain a material capable of blocking heat or flame. For example, the pad 250 may contain an insulating or flame-retardant material such as silicone or mica.

[0071] The busbar frame assembly 230 can be disposed on the front and rear sides of the plurality of battery cells 220 respectively. The busbar frame assembly 230 can be electrically connected to the electrode leads 224 of the plurality of battery cells 220.

[0072] The front busbar frame assembly 230 may include power terminals 231. Power terminals 231 may be electrically connected to multiple battery cells 220. Power terminals 231 may be configured as a pair. Power terminals 231 may be exposed to the outside of the battery module 200. Power terminals 231 may be electrically connected to another battery module 200 or a BMS (Battery Management System).

[0073] A pair of end caps 240 can be attached to the front and rear sides of the frame 210, respectively. The pair of end caps 240 can cover the front and rear sides of the frame 210. The end caps 240 can have a square shape.

[0074] Figure 6 It shows Figure 3 The image shows the exhaust plate 400. Figure 7 It is along Figure 1 The cross-sectional view taken by line A-A'. See also Figure 2 , Figure 3 , Figure 6 and Figure 7 The vent plate 400 may have multiple first vent holes 403. The vent plate 400 may cover multiple battery modules 200. For example, the vent plate 400 may cover three battery modules 200. Multiple vent plates 400 may be configured.

[0075] The exhaust plate 400 can divide the exhaust space VS. Multiple first exhaust ports 403 can connect to the divided exhaust space VS. The multiple first exhaust ports 403 can allow exhaust gas G to pass through.

[0076] When the exhaust gas G passes through the first exhaust port 403, the energy of the exhaust gas G can be reduced. The exhaust gas G can pass through the first exhaust port 403 and diffuse over a wide area.

[0077] The vent plate 400 may include a ridge 401 projecting toward the battery pack cover 150. Multiple ridges 401 may be provided. The ridges 401 may extend in a front-back direction or an X-axis direction. Multiple ridges 401 may be arranged in a left-right direction or a Y-axis direction.

[0078] The exhaust plate 400 may include valleys 402 protruding toward the battery module 200. Multiple valleys 402 may be provided. Valleys 402 may extend in a front-back direction or an X-axis direction. Multiple valleys 402 may be arranged in a left-right direction or a Y-axis direction. Multiple ridges 401 and multiple valleys 402 may be arranged alternately in a left-right direction or a Y-axis direction.

[0079] The exhaust plate 400 has ridges 401 and valleys 402, thereby stably ensuring the exhaust space VS.

[0080] The exhaust plate 400 can contact the battery module 200. Multiple valleys 402 of the exhaust plate 400 can contact the battery module 200. Multiple valleys 402 of the exhaust plate 400 can contact the top plate 210a.

[0081] The exhaust plate 400 can provide a restorative force against narrowing of the exhaust space by contacting the battery module 200.

[0082] The vent plate 400 can contact the battery pack cover 150. Multiple ridges 401 of the vent plate 400 can contact the battery pack cover 150.

[0083] The exhaust plate 400 can provide a restorative force against narrowing of the exhaust space by contacting the battery pack cover 150.

[0084] See Figure 2 , Figure 3 , Figure 6 and Figure 7 The exhaust plate 400 can be fastened, connected, fixed, attached, or mounted to the first partition wall 310. Valleys 402 of the exhaust plate 400 can be fastened, connected, fixed, attached, or mounted to the upper surface of the first partition wall 310. Fastening members S can fasten the valleys 402 to the first partition wall 310. Multiple fastening members S can be provided.

[0085] Some of the valleys 402 of the exhaust plate 400 can be fastened to the first partition wall 310. Some of the valleys 402 of the exhaust plate 400 can contact the battery module 200.

[0086] The exhaust plate 400 is fastened to the first partition wall 310, thereby stably ensuring the exhaust space VS.

[0087] Figure 8 It is shown Figure 7 A diagram illustrating the modified implementation method. See also... Figure 8The vent plate 400 can be fastened, connected, fixed, attached, or mounted to the battery pack cover 150. The ridge 401 of the vent plate 400 can be fastened, connected, fixed, attached, or mounted to the lower surface of the battery pack cover 150. Fastening members S can fasten the ridge 401 to the battery pack cover 150. Multiple fastening members S can be provided.

[0088] Some of the ridges 401 of the vent plate 400 can be fastened to the battery pack cover 150. Some of the ridges 401 of the vent plate 400 can contact the battery pack cover 150.

[0089] The exhaust plate 400 is fastened to the battery pack cover 150, thereby stably ensuring the exhaust space VS.

[0090] Figure 9 This indicates when a thermal event occurs. Figure 7 A diagram showing the changes in [the sample / sample]. See also [the diagram / sample]. Figure 7 and Figure 9 When a thermal event occurs, the exhaust gas G and particulate matter F can be discharged to the outside of the battery module 200 through the second exhaust port 211.

[0091] The exhaust gas G can collide with the exhaust plate 400. The exhaust gas G can flow in the exhaust space VS through the first exhaust port 403. The energy of the exhaust gas G is reduced by colliding with the exhaust plate 400. Due to its reduced energy, the exhaust gas G can propagate over a wide range. This reduces the heat energy propagated per unit area.

[0092] Particle F can collide with the exhaust plate 400. Particle F can flow in the exhaust space VS through the first exhaust port 403. The energy of particle F can be reduced by colliding with the exhaust plate 400. When the energy of particle F decreases, particle F can sink under the action of gravity. As particle F flows through the exhaust space VS, particle F will gradually sink and be prevented from being discharged outside the battery pack 1000.

[0093] Figure 10 This is a diagram showing the flow of the emitted gas G. See also... Figure 10 When a thermal event occurs, the exhaust gas G can flow in the exhaust space VS through the first exhaust port 403 of the exhaust plate 400. The exhaust gas G can flow in the left-right direction or the Y-axis direction. The exhaust gas G can be discharged to the outside of the battery pack 1000 through the exhaust device 500. The exhaust gas G can be discharged to the outside of the battery pack 1000 at a significantly reduced flow rate. The exhaust gas G can be discharged to the outside of the battery pack 1000 at a reduced temperature.

[0094] When a thermal event occurs, particles F can flow into the exhaust space VS through the first exhaust port 403 of the exhaust plate 400. Particles F can flow in the left-right direction or along the Y-axis. As particles F flow into the exhaust space VS, their velocity can gradually decrease, and they can sink under the influence of gravity. Particles F can sink into the housing 100 without being discharged to the outside of the battery pack 1000.
