Description

Technical Field

[0001] This invention relates to a battery container.

[0002] This application is based on and claims priority to Korean Patent Application No. 10-2024-0143206, filed with the Korean Intellectual Property Office on October 18, 2024, the disclosure of which is incorporated herein by reference. Background Technology

[0003] 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 attracted much attention because they have advantages over nickel-based rechargeable batteries, such as free charging and discharging due to almost no memory effect, very low self-discharge rate, and high energy density.

[0004] Recently, with the increasing prominence of issues such as power shortages and eco-friendly energy, energy storage systems (ESS) for storing generated electricity are attracting more attention. For example, smart grid systems have been proposed as one way to regulate electricity supply and demand. Consumer electricity consumption is not always constant but can fluctuate frequently. As a representative example, electricity consumption increases sharply in the afternoon during summer due to the use of cooling systems, and then decreases sharply at night. Thus, in terms of electricity consumption, it is not constant and can fluctuate frequently, but in terms of electricity supply, even if the generated electricity is adjusted to a certain level, it is practically difficult to match such electricity consumption. Therefore, this imbalance between electricity supply and demand can lead to either oversupply or shortage of electricity. Smart grid systems can flexibly store and regulate electricity to solve this problem. A smart grid system can be considered a concept that stores electricity in areas or when there is an oversupply and supplies the stored electricity to areas or when there is a shortage. One of the key components in building such a smart grid system is the energy storage system for storing electricity. In addition, with the recent commercialization of electric vehicles, energy storage systems can also be used in facilities for charging electric vehicles, such as charging stations.

[0005] Such energy storage systems can include multiple battery containers. Furthermore, in the event of a thermal event, it is necessary to reduce the explosion pressure to prevent the battery containers from exploding. To meet these requirements, there is an increasing need to vent flammable or explosive gases from inside the battery containers to the outside. Summary of the Invention

[0067] Reference Figures 4 to 7The locking assembly 300 can be installed inside the housing 100. The locking assembly 300 can be installed on the inner surface of the side panel 120. For example, the locking assembly 300 can be installed on the inner surface of the right side panel 120. The locking assembly 300 can be installed on the inside of the frame 160.

[0068] The locking assembly 300 may include a second housing 310. The second housing 310 may provide space therein. A second part 320 may be installed in the second housing 310. The second part 320 may include a second hook portion 321.

[0069] The second rotating shaft 330 can be installed in the second housing 310. The second rotating shaft 330 can extend along the vertical direction or the Z-axis direction. The second rotating shaft 330 can pass through the second part 320. The second part 320 can be rotatably mounted relative to the second rotating shaft 330.

[0070] The locking assembly 300 may include a second torsion spring 340. The second torsion spring 340 may be coupled to the second rotation shaft 330. Multiple second torsion springs 340 may be provided. The second torsion spring 340 may provide a restoring force to the second part 320. For example, the second torsion spring 340 may provide a counterclockwise restoring force relative to the rotation of the second part 320.

[0071] The second housing 310 may include an inner wall 311 located at the rear of the second rotation shaft 330. A locking portion 350 may be located at the rear of the inner wall 311. The locking portion 350 may be located between the rear wall 312 and the inner wall 311. An elastic member 360 may be located between the locking portion 350 and the inner wall 311. For example, the elastic member 360 may be a coil spring. Multiple elastic members 360 may be provided. The elastic member 360 may provide a restoring force to the locking portion 350. The elastic member 360 may provide a restoring force that pushes the locking portion 350 backward. The locking portion 350 may secure the second part 320. The locking portion 350 may secure the second part 320 so that it does not rotate.

[0072] The locking assembly 300 may include a trigger member 370 disposed in the second housing 310. The trigger member 370 may be disposed to the rear wall 312 of the second housing 310. The trigger member 370 may include a retainer 371. The retainer 371 may protrude from the rear wall 312. The trigger member 370 may include a glass bulb 372.

[0073] The trigger member 370 can be configured to fail in the event of a thermal event. When the trigger member 370 fails, it may be unable to support the locking part 350. When the trigger member 370 fails, the locking part 350 can move rearward or along the -X axis via the elastic member 360. As the locking part 350 moves, the second part 320 can be released from its fixation. As the locking part 350 moves, the second part 320 can rotate.

[0074] The glass bulb 372 can be configured to rupture at a specific temperature or higher. For example, the glass bulb 372 may contain liquid, and when the temperature inside the housing 100 rises, the volume of the liquid expands, causing the glass bulb 372 to rupture. The glass bulb 372 may rupture and detach from the retainer 371. The ruptured glass bulb 372 may fall due to gravity. When the glass bulb 372 is damaged, it may fail to support the locking part 350. When the glass bulb 372 is damaged, the locking part 350 may move rearward or along the -X axis via the elastic member 360. As the locking part 350 moves, the fixation of the second part 320 can be released. As the locking part 350 moves, the second part 320 can rotate.

[0075] Multiple triggering members 370 can be provided. Multiple retaining members 371 can be provided. Multiple glass bulbs 372 can be provided so that they correspond to the retaining members 371 in a one-to-one relationship. The locking part 350 can only move through the elastic member 360 when all triggering members 370 are damaged. The locking part 350 can only move through the elastic member 360 when all glass bulbs 372 are broken.

[0076] Because multiple trigger members 370 are provided, the movement of the locking part 350 can be precisely executed. Even if the temperature inside the housing 100 does not rise, some trigger members 370 may be damaged by vibrations or impacts applied to the battery container 1000. For example, the glass bulb 372 may be damaged by impacts from the user manually opening and closing the door 200. However, because multiple trigger members 370 are provided, the locking part 350 will not move even if some trigger members 370 are damaged. Because multiple trigger members 370 are provided, the locking part 350 can move when the temperature inside the housing 100 rises.

[0077] Because multiple triggering elements 370 are provided, vibrations or impacts applied to each glass bulb 372 can be dispersed. This prevents the glass bulb 372 from being damaged by vibration or impact.

[0078] The trigger member 370 may include a gasket 373. The gasket 373 may be located at the front end of the glass bulb 372. The gasket 373 may be located between the glass bulb 372 and the locking part 350. The gasket 373 may be attached, connected, or fixed to the front end of the glass bulb 372. The gasket 373 may also be attached, connected, or fixed to the rear end of the locking part 350.

[0079] Gasket 373 may be located at the rear end of glass bulb 372. Gasket 373 may be located between glass bulb 372 and retainer 371. Gasket 373 may be attached, coupled, or secured to the rear end of glass bulb 372. Gasket 373 may also be attached, coupled, or secured to retainer 371. Gasket 373 may comprise an elastic material. For example, gasket 373 may comprise a rubber material. Gasket 373 may absorb vibrations or shocks applied to battery container 1000. Gasket 373 may prevent glass bulb 372 from being damaged by vibration or shock.

[0080] Figure 8 It is shown Figure 6 A diagram of a modified embodiment. (Refer to...) Figure 8 The triggering member 370 may include a melting member 374. The melting member 374 may contain a metallic material that can melt at low temperatures. For example, the melting member 374 may be a molten wire.

[0081] The molten member 374 may be located inside the retainer 371. The molten member 374 may support the locking part 350. The locking part 350 may be located between the molten member 374 and the elastic member 360. The molten member 374 and the elastic member 360 may be in a balanced state. The locking part 350 may be fixed between the molten member 374 and the elastic member 360.

[0082] The molten member 374 can be configured to melt at or above a specific temperature. As the molten member 374 melts, it may no longer support the locking part 350. As the molten member 374 melts, the locking part 350 can move rearward or along the -X-axis direction via the elastic member 360. As the locking part 350 moves, the second part 320 can be released from its fixation. As the locking part 350 moves, the second part 320 can rotate.

[0083] Figure 9 It is along Figure 5 A cross-sectional view taken along line B-B'. (Refer to...) Figure 9 The second part 320 may include a protrusion 323. The protrusion 323 may protrude from the second hook portion 321. The protrusion 323 may be formed on the second hook portion 321. The locking part 350 may include a fixing hole 351. The protrusion 323 may be inserted into the fixing hole 351. By inserting the protrusion 323 into the fixing hole 351, the locking part 350 can fix the second part 320.

[0084] Figure 10 This indicates that when the internal temperature of the battery container 1000 rises... Figure 9 A diagram showing the changes within. (Refer to...) Figure 10 When the internal temperature of the battery container 1000 rises, the trigger member 370 may be damaged. All of the glass bulbs 372 may be destroyed. Additionally, the locking part 350 can move rearward or along the -X axis via the elastic member 360. The protrusion 323 can disengage from the fixing hole 351. The second part 320 can rotate due to the restoring force of the second torsion spring 340.

[0085] Figure 11 It is along Figure 1 The cross-sectional view taken along line A-A'. (Refer to...) Figure 11 When the door 200 is closed, the first hook portion 221 and the second hook portion 321 can engage with each other. The first hook portion 221 can be rotatably connected to the first rotating shaft 230. The second hook portion 321 can be rotatably connected to the second rotating shaft 330.

[0086] The first torsion spring 240 provides a restoring force to rotate the first hook portion 221 or the first part 220 clockwise. The second torsion spring 340 provides a restoring force to rotate the second hook portion 321 or the second part 320 counterclockwise. The rotational directions in which the first torsion spring 240 provides the restoring force and the rotational directions in which the second torsion spring 340 provides the restoring force can be opposite to each other.

[0087] When the protrusion 323 is inserted into the fixing hole 351 and triggers the member 370 to support the locking part 350, the second part 320 can remain fixed.

[0088] Figures 12 to 16 This indicates that when the internal temperature of the battery container 1000 rises... Figure 11 A graph showing the changes in [the data / process].

[0089] Reference Figure 12 The trigger member 370 may be damaged due to increased internal temperature of the battery container 1000. If all the glass bulbs 372 are destroyed, the locking part 350 can be moved rearward or in the -X axis direction by the elastic member 360. At the same time, the fixing hole 351 can disengage from the protrusion 323.

[0090] refer to Figure 13The second part 320 may include an opening member 322. The opening member 322 extends from the second hook portion 321. The second part 320 may be integrally formed. When the connection between the locking part 350 and the second part 320 is released, the second part 320 can rotate counterclockwise about the second rotation axis 330 via the second torsion spring 340. As the second part 320 rotates, the connection between the first hook portion 221 and the second hook portion 321 can be released. As the second part 320 rotates, the opening member 322 can contact the first hook portion 221. When the second part 320 rotates, the opening member 322 can push the first hook portion 221, causing the first part 220 to rotate clockwise.

[0091] Reference Figures 14 to 16 When the second part 320 rotates counterclockwise around the second rotation axis 330, the opening member 322 can push the first hook part 221. When the opening member 322 pushes the first hook part 221, the door 200 can be opened. The door 200 can be opened by rotating clockwise. The opening member 322 can open the door 200 until the second part 320 reaches the maximum angle that the second part 320 can rotate counterclockwise.

[0092] Figure 17 This diagram shows the door 200 opening when the internal temperature of the battery container 1000 rises. (Refer to...) Figure 17 When the internal temperature of the battery container 1000 rises, the door 200 can be opened by the locking component 300. With the door 200 open, gases or similar substances inside the battery container 1000 can be released to the outside.

[0093] When the internal temperature of the battery container 1000 rises, the locking assembly 300 can open the door 200 without the use of electricity or electrical energy. The locking assembly 300 can improve the thermal safety of the battery container 1000.
