Description

Battery pack with block-type bulkhead

[0001] This application claims the benefit of priority from Republic of Korea Patent Application No. 10-2023-0158390, dated November 15, 2023, the entire contents of which are incorporated herein by reference.

[0002] The present invention relates to a structure of a battery pack that prevents heat transmission between modules. More specifically, the present invention relates to a structure of a battery pack that includes a battery module having a flange and a partition wall to which the flange is fastened, wherein heat transmission through the flange and the partition wall is prevented.

[0003] Secondary batteries, which boast high electrical properties such as high energy density and easy applicability across a wide range of product groups, are widely used not only in portable devices but also in electric or hybrid vehicles powered by electrical power sources, as well as in power storage devices. These batteries are attracting attention as a new energy source for environmental friendliness and energy efficiency, not only because they can dramatically reduce fossil fuel use, but also because they produce no byproducts from energy use.

[0004] While small mobile devices typically use one or two or three battery cells per device, medium- to large-sized devices, such as automobiles, require high output and large capacity. Therefore, medium- to large-sized battery modules, which electrically connect multiple battery cells, are used. Furthermore, these battery modules can be integrated into battery packs to achieve even higher output and capacity.

[0005] Figures 1 and 2 illustrate the structure of a battery module having a flange. Referring to these drawings, a battery module (1) having a flange (110) has a structure in which a cell stack (100) in which a plurality of pouch-type battery cells are stacked is accommodated in a housing having the flange (110). The housing may include a U-frame (101), an end plate (102), and a top plate (103), and the flange (110) may include a lower flange and an upper flange extending in the width direction from the U-frame (101) and the top plate (103), respectively.

[0006] Figures 3 and 4 illustrate the structure of a conventional battery pack having a bulkhead to which a flange is fastened. Referring to these drawings, the battery pack (P) is configured such that a plurality of battery modules (1) are embedded within a pack frame (2) having a bulkhead (21). The bulkhead (21) isolates the spaces in which the battery modules (1) are placed, and the flange (110) is fastened so that the battery modules (1) can be fixed to the pack frame (2) without movement.

[0007] Meanwhile, the cell stack (100) may catch fire due to a short circuit or the like. At this time, high-temperature gas and flame generated from the cell stack (100) may increase the temperature of the housing.

[0008] Fig. 5 illustrates a cross-section of Fig. 3. Referring to this, thermal energy resulting from ignition of the battery module (1) may be transmitted to the pack frame (2) and the flanges of other battery modules through the flange (110) and the partition wall (21) connected thereto. In this case, there is a risk that thermal runaway of the pack unit may occur due to heat transmission between the battery modules, which may cause a chain reaction of ignitions.

[0009] Therefore, a structure is required that can firmly fix the battery module to the pack frame by fastening the flange to the bulkhead, while preventing heat transfer between the modules through this.

[0010] The present invention was created under the background of the above-described prior art, and its purpose is to provide a structure of a battery pack that prevents thermal runaway of a pack unit due to heat transmission between modules.

[0011] Specifically, the present invention seeks to provide a structure of a battery pack having a battery module having a flange and a pack frame to which the flange is fastened, wherein heat transmission between modules through the flange and the pack frame is prevented.

[0012] In addition, the present invention seeks to provide a structure of a battery pack that prevents heat transfer between modules due to convection.

[0013] Another technical challenge of the present invention is to provide a structure of a battery pack in which a battery module is firmly fixed to a pack frame while preventing heat transmission between modules, and a structure of a vehicle incorporating the same.

[0014] The technical objectives of the present invention are not limited to the purposes mentioned above. Other objectives and advantages of the present invention not mentioned above can be understood through the following description and will be more clearly understood through the embodiments of the present invention. Furthermore, it will be readily apparent that the objectives and advantages of the present invention can be realized by the means and combinations thereof set forth in the claims.

[0015] In order to solve the above problem, the present invention provides a battery pack structure including: a plurality of battery modules spaced apart in the width direction and having one or more flanges extending in one or both width directions; a pack frame accommodating the battery modules and having side walls and a bottom plate; and a plurality of blocks extending upward from the bottom plate and to which the flanges are fixed; wherein the battery modules are adjacent to each other and include predetermined first modules and second modules each having a first flange and a second flange, and the blocks include predetermined first blocks and second blocks arranged between the first module and the second module, and the first block supports the first flange but is not connected to the second flange, and the second block supports the second flange but is not connected to the first flange.

[0016] Since the first module and the second module are supported by the first block and the second block, which are not connected to each other, the battery module can be stably supported on the pack frame, while heat transmission between the battery modules through the flange can be prevented.

[0017] At this time, the bottom surface of at least one of the battery modules may be spaced upward from the bottom plate. Alternatively, an insulating material may be interposed between the bottom surface of at least one of the battery modules and the bottom plate. Accordingly, heat conduction from the battery module to the bottom plate can be minimized, and heat transmission between modules through the bottom plate can also be prevented.

[0018] The first block and the second block may be juxtaposed to each other in the width direction. In other words, the first block and the second block may be arranged with a predetermined gap between them in the width direction, and the first block may be arranged on the side of the first module, and the second block may be arranged on the side of the second module. At this time, each of the first block and the second block may be a single member extending in the length direction, or may include a plurality of members arranged in the length direction.

[0019] Alternatively, the first block and the second block may be arranged in multiple numbers in the longitudinal direction. At this time, the first block and the second block may be arranged one or multiple times alternately in the longitudinal direction. At this time, the first flange and the second flange may extend in the width direction at different positions along the longitudinal direction and be connected to the first block and the second block, respectively.

[0020] The pack frame may include a heat-resistant isolation member that is supported by the first block and the second block and isolates the first module and the second module in the width direction. Preferably, the isolation member may cover both sides of the first block and the second block in the width direction. By providing the isolation member, heat transmission due to convection between the first module and the second module can be prevented.

[0021] The above-mentioned insulating member may be provided such that a portion thereof is interposed between the flange and the block. Accordingly, heat conduction from the flange to the block can be delayed or prevented.

[0022] According to one embodiment of the present invention, the isolation member may have a shape that covers both the upper and widthwise sides of the first block and the second block. In other words, the isolation member may include a box-shaped member that is substantially open on both longitudinal sides and the lower side and is covered by the first block and the second block.

[0023] The isolation member according to one embodiment of the present invention may include a mica (MICA) material.

[0024] The above block may include a third block that supports the isolation member but is not connected to the flange. The third block can improve the structural stability of the isolation member by supporting the isolation member without exchanging heat with the first flange and the second flange.

[0025] At this time, the third block can be arranged longitudinally with the first block and the second block.

[0026] The battery module may include a predetermined outermost module having an outermost flange adjacent to one widthwise side of the sidewall and extending in the other widthwise side, wherein the block may include a predetermined fourth block disposed between the outermost module and the sidewall, supporting the outermost flange, but spaced apart from the sidewall in the widthwise direction. Since the outermost module is not directly connected to the sidewall but is supported by the fourth block, heat transmission between the outermost modules through the sidewall can be prevented.

[0027] At this time, in order to prevent heat transmission between the outermost modules through the fourth block, it is preferable that the fourth block be connected to only one battery module.

[0028] Each of the above fourth blocks may be a single member extending in the longitudinal direction, or may include a plurality of members arranged in the longitudinal direction.

[0029] The pack frame may include a heat-resistant isolation member that is supported by the fourth block and provides widthwise insulation between the outermost module and the side wall. Preferably, the isolation member may cover both sides of the fourth block in the widthwise direction. By providing the isolation member, heat transmission due to convection between the outermost module and the side wall can be prevented.

[0030] The above-mentioned insulating member may be provided such that a portion thereof is interposed between the flange and the block. Accordingly, heat conduction from the flange to the block can be delayed or prevented.

[0031] According to one embodiment of the present invention, the isolation member may have a shape that covers both the upper and widthwise sides of the fourth block. In other words, the isolation member may include a box-shaped member that is substantially open on both longitudinal sides and the lower side, and is covered by the fourth block.

[0032] The isolation member according to one embodiment of the present invention may include a mica (MICA) material.

[0033] The above block may include a fifth block that supports the isolation member but is not connected to the outermost flange. The fifth block can improve the structural stability of the isolation member by supporting the isolation member without exchanging heat with the fourth flange.

[0034] At this time, the fifth block can be arranged longitudinally with the fourth block.

[0035] The present invention also provides a structure of a vehicle including the battery pack. The battery pack may be installed in the vehicle as a power source. The vehicle may be an electric vehicle or a hybrid vehicle. The vehicle may be a two-wheeled vehicle or a four-wheeled vehicle. However, the structure of the vehicle is not limited to the above, and the battery pack need not necessarily serve as the vehicle's power source.

[0036] The present invention can provide a structure of a battery pack that prevents thermal runaway of a pack unit due to heat transfer between modules.

[0037] Specifically, the present invention provides a battery pack structure in which heat transfer between modules is prevented by providing blocks to which each flange is connected separately, in a battery pack having a battery module having a flange and a pack frame to which the flange is connected.

[0038] In addition, the present invention seeks to provide a structure of a battery pack that prevents heat transfer between modules due to convection by providing an isolation member that isolates spaces between battery modules.

[0039] Another technical challenge of the present invention is to provide a structure of a battery pack in which a battery module is firmly fixed to a pack frame while preventing heat transmission between modules, and a structure of an automobile incorporating the same.

[0040] In addition, the present invention may have various other effects, which will be described in each embodiment, or the description of effects that can be easily inferred by a person skilled in the art will be omitted.

[0093]

[0094] [Rough structure of a battery pack]

[0095] Hereinafter, with reference to FIGS. 6 and 7, a general structure of a battery pack having a bulkhead according to one embodiment of the present invention will be described.

[0096] Figure 6 illustrates the exterior of a battery pack according to one embodiment of the present invention. Referring to these drawings, a battery pack (P) according to one embodiment of the present invention may include a plurality of battery modules (1) arranged in the width direction and a pack frame (2) accommodating the same. The pack frame (2) may include a bottom plate (201) and side walls (202).

At this time, an insulating material (not shown) may be provided between the bottom surface of the battery module (1) and the bottom plate (201). Accordingly, heat transmission between the battery modules (1) due to heat conduction through the bottom plate (201) can be prevented.

[0102]

[0103] [Block structure of bulkhead]

[0104] Hereinafter, with reference to FIGS. 8 to 14, the structure of a bulkhead constituting a battery pack according to one embodiment of the present invention will be described in detail.

[0105] Fig. 8 illustrates the arrangement of blocks according to one embodiment of the present invention, and Figs. 9 and 10 illustrate a first module and a second module fastened to a pack frame according to one embodiment of the present invention, respectively. Referring to these drawings, the bulkhead (21) may include a plurality of blocks (210). The blocks (210) may include a first block (211) that supports the first module (11) but is not connected to the second module (12), and a second block (212) that supports the second module (12) but is not connected to the first module (11).

[0106] The first block (211) and the second block (212) may be arranged in parallel with each other in the width direction, or may be arranged in multiple numbers in the length direction. According to one embodiment of the present invention, the first block (211) and the second block (212) may be arranged in multiple numbers alternately and repeatedly in the length direction.

[0107] Figures 11 and 12 illustrate enlarged views of the main portion of a battery module fastened to a pack frame according to one embodiment of the present invention. Referring to these drawings, the first flange (111) and the second flange (112) according to one embodiment of the present invention may extend from different positions along the longitudinal direction and be connected to the first block (211) and the second block (212), respectively. In this way, as the first flange (111) and the second flange (112) are connected to the first block (211) and the second block (212) which are separated from each other, the first flange (111) and the second flange (112) may be fixed to the pack frame (2), while heat transmission between the battery modules (1) through the flange (110) and the partition wall (21) may be prevented.

[0108] Referring again to Fig. 11, the battery module (1) may include a predetermined outermost module (14) adjacent to one widthwise side of the side wall (202). The outermost module (14) may have an outermost flange (114) extending to the other widthwise side toward the side wall (202).

[0109] The block (210) may include a fourth block (214) disposed between the outermost module (14) and the side wall (202). The fourth block (214) may support the outermost flange (114) but may be spaced apart from the side wall (202) in the width direction. Accordingly, heat transmission through the side wall (202) between the outermost modules (14) may be prevented.

[0110] At this time, in order to prevent heat transmission between the outermost modules (14) through the fourth block (214), it is preferable that each of the fourth blocks (214) be connected to only one battery module (1).

[0111] Each of the above fourth blocks (214) may be a single member extending in the longitudinal direction, or may include a plurality of members arranged in the longitudinal direction.

[0112] Figures 13 and 14 illustrate the arrangement of an isolation member according to one embodiment of the present invention. Referring to these drawings, the bulkhead (21) may include a heat-resistant isolation member (215) that is supported by the block (210) and isolates the space in which the battery module (1) is arranged in the width direction. The isolation member (215) according to one embodiment of the present invention may include a mica (MICA) material.

[0113] Preferably, the isolation member (215) can cover both sides in the width direction of the first block (211) and the second block (212) between the first module (11) and the second module (12), and can cover both sides in the width direction of the fourth block (214) between the outermost module (14) and the side wall (202). By providing the isolation member (215), heat propagation due to convection between the battery modules (1) can be prevented.

[0114] The above-mentioned isolation member (215) may be interposed between the flange (110) and the block (210). Accordingly, heat conduction between the flange (110) and the block (210) may be delayed or prevented.

[0115] The isolation member (215) according to one embodiment of the present invention is a member that forms the upper surface and both width-direction surfaces of the partition wall (21), and includes a mica material, and can be provided one by one for each partition wall (21).

[0116] Between the first module (11) and the second module (12), a third block (213) may be provided that supports the isolation member (215) but is not connected to the flange (110). In addition, between the outermost module (14) and the side wall (202), a fifth block (not shown) that supports the isolation member (215) but is not connected to the flange (110) may be provided. By providing the third block (213) and / or the fifth block, the partition wall (21) can not conduct heat between the flanges (110) and at the same time, the isolation member (215) can be stably supported.

[0117] Fig. 15 shows a cross-section of a battery pack according to an embodiment of the present invention. Referring to this, in the battery pack (P) according to an embodiment of the present invention, the first flange (111) extending from the first module (11) is connected to the first block (211) with the isolation member (215) interposed therebetween, and the second flange (112) extending from the second module (12) is connected to the second block (212) with the isolation member (215) interposed therebetween, so that little heat can be conducted between the first flange (111) and the second flange (112).
