Description

battery pack

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

[0002] This application is a priority application for Korean Patent Application No. 10-2024-0128911 filed on September 24, 2024, and all contents disclosed in the specification and drawings of said application are incorporated into this application by reference.

[0003] As the demand for portable electronic products such as smartphones, tablet PCs, and smartwatches increases significantly and electric vehicles become increasingly widespread, research on batteries installed in them, particularly secondary batteries capable of repeated charging and discharging, is actively underway.

[0004] Currently commercialized secondary batteries include nickel-cadmium, nickel-hydrogen, nickel-zinc, and lithium secondary batteries. Among these, lithium secondary batteries are gaining attention for their advantages, such as the ability to freely charge and discharge with almost no memory effect compared to nickel-based secondary batteries, a very low self-discharge rate, and high energy density.

[0005] These lithium secondary batteries primarily use lithium-based oxides and carbon materials as the positive and negative active materials, respectively. The lithium secondary battery comprises an electrode assembly in which a positive plate and a negative plate, each coated with the positive and negative active materials, are arranged with a separator in between, and an outer casing, namely a battery case, that seals and houses the electrode assembly together with an electrolyte.

[0006] Generally, lithium secondary batteries can be classified according to the shape of the casing into can-type secondary batteries, in which the electrode assembly is embedded in a metal can, and pouch-type secondary batteries, in which the electrode assembly is embedded in a pouch of aluminum laminate sheet.

[0007] Recently, secondary batteries are widely used for driving or energy storage not only in small devices such as portable electronic devices but also in medium-to-large devices such as electric vehicles and Energy Storage Systems (ESS). A single battery module can be formed by housing multiple such secondary batteries together inside a module case while electrically connected. In this case, each secondary battery included in a single battery module can be referred to as a battery cell. Furthermore, multiple such battery modules can be connected to form a single battery pack.

[0008] However, when a battery pack contains multiple battery modules, and each module contains multiple battery cells, it may be vulnerable to thermal chain reactions between modules or cells. For example, if an event such as thermal runaway occurs within a single battery module, it is necessary to suppress the propagation of this runaway to other battery modules or cells. If the propagation of thermal runaway between modules or cells is not properly suppressed, an event originating in a specific module or cell may trigger a chain reaction of thermal reactions in other modules or cells, potentially causing explosions or fires, or significantly amplifying their scale.

[0009] In particular, if an event such as thermal runaway occurs in a single battery module, gases or flames may be randomly released to the outside. If the release of such gases or flames is not properly controlled, they may be released toward other battery modules, potentially causing a thermal chain reaction in those modules. Specifically, module terminals may be located on the front side of a battery module to provide electrical connections to other battery modules or battery packs, such as module busbars. Therefore, if flames are released toward the front of such a battery module, they can damage the module terminals within the battery pack and cause an electrical short circuit. Furthermore, since other battery modules may be located in front of a specific battery module, if flames are released toward the front of that module, the emitted flames may spread toward other modules, making it easy for fire to spread between battery modules.

[0010] If thermal propagation between battery modules or between battery cells is not properly controlled, a rapid voltage drop in the battery module or battery pack may occur. This can lead to a sudden shutdown of the device equipped with the battery module or battery pack, causing unexpected damage. For example, if a sudden voltage drop in the battery pack occurs while an electric vehicle is in operation, there may not be enough time to move the electric vehicle to a safe location.

[0011] Furthermore, if thermal propagation between battery modules or battery cells is not properly controlled and a fire or explosion occurs suddenly, there is a high possibility of causing casualties to users. For example, if thermal runaway occurs in an electric vehicle and a certain amount of time is not secured before it progresses into a full-scale fire, the occupants may not be able to escape safely.

[0012] Accordingly, the present invention is devised to solve the above-mentioned problems and aims to provide a battery pack with an improved structure capable of appropriately controlling the discharge of flames, etc. generated inside the battery module, and a vehicle including the same.

[0013] In addition, the objective of the present invention may be to provide a venting space through which venting gas can flow when a thermal event occurs.

[0014] In addition, the objective of the present invention may be to suppress deformation of the battery module and the pack cover when a thermal event occurs.

[0015] In addition, the objective of the present invention may be to suppress the propagation of thermal events by reducing the energy of venting gas and particles.

[0016] In addition, the present invention may block the discharge of particles, such as flammable particles, to the outside of the battery pack.

[0017] However, the technical problems that the present invention aims to solve are not limited to those described above, and other unmentioned problems will be clearly understood by those skilled in the art from the description of the invention below.

The base plate (110) may have a rectangular 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 an internal space of the battery pack (1000).

[0049] The case (100) may include side walls (120). The side walls (120) may be installed, fastened, joined, fixed, or attached to the upper surface of the base plate (110). The side walls (120) may consist of four. The side walls (120) may be arranged along the perimeter of the base plate (110). The side walls (120) may form the exterior of the battery pack (1000). The side walls (120) may provide an internal space.

[0050] The case (100) may include a pack cover (150). The pack cover (150) may have a square plate shape. The pack cover (150) may have a flat plate shape.

[0051] A battery cell (220, see FIG. 5) may be located inside a case (100). A plurality of battery cells (220) may be provided. In this case, the battery cell (220) may refer to a secondary battery. In particular, the battery cell (220) may be a pouch-type secondary battery. However, the shape of the battery cell (220) is not limited to a pouch shape and may have various shapes such as a cylindrical shape or a rectangular shape.

[0052] The venting plate (400) may be positioned between the battery cell (220) and the pack cover (150). The venting plate (400) may have a corrugated shape.
