Description

battery module

[0001] The present invention relates to a battery module.

[0002] This application claims priority to Korean Patent Application No. 10-2023-0096978, filed on July 25, 2023, the entire disclosure of which is incorporated herein by reference.

[0003] As demand for portable electronic products such as laptops, video cameras, and mobile phones rapidly increases and the commercialization of robots and electric vehicles becomes more widespread, research into high-performance secondary batteries capable of repeated charging and discharging is actively underway.

[0004] Currently commercialized secondary batteries include nickel-cadmium batteries, nickel-hydrogen batteries, nickel-zinc batteries, and lithium secondary batteries. Among these, lithium secondary batteries are receiving attention for their advantages of being able to charge and discharge freely, having a very low self-discharge rate, and having a high energy density, as they have almost no memory effect compared to nickel-based secondary batteries.

[0005] These lithium secondary batteries primarily use lithium oxide and carbon materials as the positive and negative electrode active materials, respectively. Lithium secondary batteries comprise an electrode assembly comprising positive and negative plates coated with the positive and negative electrode active materials, respectively, with a separator interposed between them, and an outer case, i.e., a battery case, that seals and encloses the electrode assembly together with an electrolyte.

[0006] In general, lithium secondary batteries can be classified into can-type secondary batteries in which the electrode assembly is built into a metal can and pouch-type secondary batteries in which the electrode assembly is built into a pouch of an aluminum laminate sheet, depending on the shape of the outer packaging material.

[0007] Recently, secondary batteries have been widely used for power and energy storage, not only in small devices like portable electronic devices but also in medium- to large-sized devices like electric vehicles and energy storage systems (ESS). Multiple secondary batteries can be electrically connected and housed within a module case to form a single battery module. Furthermore, multiple such battery modules can be connected to form a single battery pack.

[0008] However, when multiple secondary batteries (battery cells) or battery modules are densely packed in a confined space, they can be vulnerable to thermal events. Specifically, if a thermal runaway event occurs in a single battery cell, high-temperature gases, flames, and heat can be generated. If these gases, flames, or heat are transferred to other battery cells within the same battery module, an explosive chain reaction, such as thermal propagation, can occur. This chain reaction can not only cause a fire or explosion in the battery module in question, but can also trigger fires or explosions in other battery modules.

[0009] Moreover, for medium- to large-sized battery packs, such as those used in electric vehicles, the risk of a thermal chain reaction can be even greater due to the inclusion of a large number of battery cells and battery modules to increase output and / or capacity. Furthermore, battery packs installed in electric vehicles may be surrounded by users, such as drivers. Therefore, if a thermal event occurring in a specific battery module is not properly controlled and a chain reaction occurs, it could result in significant property damage and even human casualties.

[0010] Additionally, it is important to enhance electrical safety by preventing the power of the battery cell from shorting to adjacent components and causing current leakage even if a thermal event occurs.

[0011] The present invention aims to solve the above-mentioned problems and other problems.

[0012] Another object of the present invention may be to provide a battery module with improved electrical safety when a thermal event occurs.

[0013] Another object of the present invention may be to provide a battery module including a structure capable of maintaining an electrical insulation state between an end cover and a battery cell when a thermal event occurs.

[0014] Another object of the present invention may be to provide a battery module that is easy to control venting when a thermal event occurs.

In addition, the insulating cover (400) can entirely cover the rear side of the busbars (320, 330) of the rear side busbar frame assembly (300). As a result, the busbars (320, 330) of the rear side busbar frame assembly (300) may not be exposed to the outside.

[0068] According to this configuration of the present invention, the insulating cover (400) can stably maintain the electrical insulation state of the bus bar (320, 330) and the end cover (500).

[0069] Hereinafter, the front side busbar frame assembly (300), the insulating cover (400), and the end cover (500) will be described. Referring to FIGS. 3 to 6, the busbar frame assembly (300) of the battery module according to an embodiment of the present invention may include a hook (211) that protrudes forward. The hook (211) may protrude from the frame body (310). The hook (211) may be made of the same material as the frame body (310). In addition, the hooks (211) may be provided in multiple numbers. The insulating cover (400) may be coupled, fastened, or fixed to the hook (211). The insulating cover (400) may be coupled, fastened, or fixed to a plurality of hooks (211).

[0070] According to this configuration of the present invention, the insulating cover (400) can be stably fixed in position. The insulating cover (400) may include a highly rigid mica material, and machining the shape thereof may be very limited. For example, forming a hook in the insulating cover (400) may be very limited. In addition, when the end cover (500) is made of a metal material, machining the shape thereof may be very limited. For example, forming a hook in the end cover (500) may be very limited. Therefore, it may be desirable to form the hook (211) in the frame body (310) made of a material that is easy to mold. By forming the hook (211) in the frame body (310), the productivity and assembling ability of the battery module may be improved.

[0071] Referring to FIGS. 3 to 6, an insulating cover (400) of a battery module according to an embodiment of the present invention may include an insulating plate (410) and a hooking groove (411). The insulating plate (410) may have a flat plate shape. In addition, the insulating plate (410) may have an overall rectangular shape. The hooking groove (411) may be formed inward from one edge of the insulating plate (410). The hooking groove (411) may be formed to penetrate the insulating plate (410). A hook (211) may pass through the hooking groove (411) and be hooked to the front surface of the insulating plate (410). A plurality of hooking grooves (411) may be provided. The hooking grooves (411) may be provided to correspond one-to-one with the hooks (211). For example, the number of hooks (411) and hooks (211) may be four, and the hooks (211) may be provided on the upper, lower, left, and right sides of the frame body (310), respectively. The bus bars (320, 330) may be located between the hooks (211).

[0072] According to this configuration of the present invention, the insulating cover (400) and the busbar frame assembly (300) can be stably combined.

[0073] Fig. 7 is a perspective view showing an end cover (500) of a battery module according to an embodiment of the present invention. Fig. 8 is a view of the end cover (500) of Fig. 7 viewed from another direction. Fig. 9 is a view showing the end cover (500) of the battery module according to an embodiment of the present invention in a separated state. Fig. 10 is a view showing the end cover (500) of the battery module according to an embodiment of the present invention when combined. Referring to Figs. 7 to 10, the end cover (500) according to an embodiment of the present invention may include an end plate (510) having a flat shape.

[0074] The end cover (500) may include a first support portion (520) protruding from the rear surface of the end plate (510). In addition, the end cover (500) may include a receiving portion (511) formed on the rear surface. The receiving portion (511) may be formed on the inner side of the first support portion (520). The receiving portion (511) may be a groove. The receiving portion (511) may not penetrate the end cover (500). The receiving portion (511) may be provided in multiple numbers. The multiple receiving portions (511) may be provided to correspond one-to-one with the hooks (211). In addition, the multiple receiving portions (511) may be positioned to correspond with the hooks (211). When the end cover (500) and the case (100) are combined, at least a portion of the hooks (211) may be received or inserted into the receiving portion (511).

[0075] According to this configuration of the present invention, the gap between the insulating cover (400) and the end cover (500) can be reduced. Alternatively, the insulating cover (400) and the end cover (500) can be in close contact. As a result, the energy density of the battery module can be improved.

[0076] Conventionally, a through hole was formed in the end cover (500) and an insulating cover (400) was fastened to the through hole. As a result, there was a risk that venting gas or flammable particles would be emitted through the through hole of the end cover (500) when a thermal event occurred.

[0077] On the other hand, according to this configuration of the present invention, since the end cover (500) does not include a through hole, even if a thermal event occurs, venting gas or ignitable particles can be prevented from being emitted through the end cover (500). As a result, venting gas or ignitable particles, etc. can be discharged upward through the venting hole (121). Therefore, venting control can be facilitated by the end cover (500).

[0078] Fig. 11 is a schematic drawing showing a part of a cross-sectional configuration along the cutting line AA' of Fig. 10. Fig. 12 is a schematic drawing showing a part of a cross-sectional configuration along the cutting line BB' of Fig. 10.

[0080] According to this configuration of the present invention, when a thermal event occurs, the fastening, fixing, joining, and attachment structures of the insulating cover (400) and the busbar frame assembly (300) may be damaged. The end cover (500) can support the insulating cover (400) so that the position of the insulating cover (400) does not become distorted. As a result, the electrical and thermal safety of the battery module can be improved.

[0081] Referring to FIGS. 10 to 15, an end cover (500) of a battery module according to an embodiment of the present invention may include a first support portion (520) protruding rearward. The first support portion (520) may extend along the perimeter of the end cover (500). The first support portion (520) may cover the perimeter, side, or edge of the insulating cover (400). In addition, at least a portion of the hook (211) may be inserted into the receiving portion (511). The receiving portion (511) may be located on the inside of the first support portion (520). In addition, the hook (211) may be located on the inside of the first support portion (520).

[0082] Referring to FIG. 15, when a thermal event occurs, the fastening, fixing, joining, and attachment structures of the insulating cover (400) and the busbar frame assembly (300) may be damaged due to the venting gas (g) and ignitable particles (f) that are emitted. In addition, when a thermal event occurs, the busbars (320, 330) may be separated from the frame body (310), and the busbars (320, 330) may move toward the end cover (500).

[0083] According to this configuration of the present invention, the first support portion (520) of the end plate (510) can support the insulating cover (400) so that the position of the insulating cover (400) is not distorted. As a result, the insulating cover (400) can prevent the end cover (500) and the bus bars (320, 330) from coming into contact.

[0084] Referring to FIGS. 10 to 15, an insulating cover (400) of a battery module according to an embodiment of the present invention may include an insulating plate (410) having a flat shape and a second support portion (420) protruding rearward from an edge of the insulating plate (410). The second support portion (420) may extend along the perimeter of the insulating cover (400). The first support portion (520) of the end cover (500) may face the second support portion (420).

[0085] According to this configuration of the present invention, the portion of the end cover (500) that supports the insulating cover (400) can be enlarged. Alternatively, the area of ​​contact between the end cover (500) and the insulating cover (400) can be widened. As a result, the insulating cover (400) can be more stably supported by the end cover (500).

[0086] FIG. 16 is a drawing showing a part of a configuration of a battery module according to another embodiment of the present invention. Referring to FIG. 16, the battery module according to another embodiment of the present invention may further include a fastening member (b) that connects an insulating cover (400) to a busbar frame assembly (300).

The fastening member (b) may include an electrically insulating material. In addition, the fastening members (b) may be provided in multiple numbers. The fastening members (b) may be provided at the upper side, the lower side, the left side, and the right side.

[0087] According to this configuration of the present invention, the insulating cover (400) can be stably coupled, fastened, or fixed to the frame body (310). In addition, since the fastening member (b) is electrically insulating, electrical safety can be maintained even if the fastening member (b) is separated and moves due to the occurrence of a thermal event.
