Description

Technical Field

[0001] The utility model relates to the technical field, and specifically relates to a storage battery with a fire extinguishing patch. Background Art

[0002] When storing backup electric energy in daily household life, a battery pack is required to store the electric energy. In recent years, the home energy storage industry has entered a period of rapid development. While users pursue the cost performance of energy storage devices, they also pay more and more attention to the use safety of batteries. In this context, each manufacturer tends to choose a safer chemical system and has done a lot of work in circuit thermal management. Among them, considering the cost, a protective cabinet is mainly used to isolate the battery from the outside world to prevent the battery from being affected by the outside temperature, or to isolate the battery from the outside world when an accident occurs to prevent the battery from coming into contact with external combustibles and expanding the fire. However, using a protective cabinet cannot solve the problem of rapid fire extinguishing. Specifically, due to manufacturing problems, the battery cells are prone to thermal runaway, and a fire source is formed inside the battery cells to bake the protective cabinet, and the fire cannot be blocked within a certain period of time.

[0003] During the use of existing lithium battery packs, problems such as overheating and too high temperature of battery monomers will occur due to factors such as untimely heat dissipation, overload, and long-term use. If these problems are not discovered and stopped in time, it is easy to cause damage to the battery monomers, and in severe cases, it will also cause fire and explosion problems. In addition, factors that cause the battery pack to catch fire and explode include short circuit, overcharge, over-discharge, etc.

[0004] The patent with the application number of WOKR21005070 discloses a battery module with a partition wall and a heat insulation layer for fire extinguishing. The battery module includes a partition wall and a heat insulation layer for preventing thermal runaway. The battery module includes at least two battery module components, the battery module components are accommodated in the internal space of a protective shell, and at least one partition board is arranged between adjacent battery stacks. The invention can prevent the sparks generated during thermal runaway and the movement of sparks to adjacent battery stacks or electrode leads; therefore, it can block the sparks generated during thermal runaway and the movement of sparks to adjacent battery cell stacks or electrode leads. The invention can only inhibit the spread of sparks and reduce losses. In the case of a large degree of deflagration, heat and flames are very likely to spread and affect the surrounding batteries, causing the fire to expand, and the safety is insufficient for storage batteries. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a storage battery with a fire extinguishing patch that can quickly inhibit thermal runaway and is easy to assemble.

[0006] To solve the above technical problems, the utility model specifically provides the following technical solutions:

[0007] A storage battery with a fire extinguishing patch, comprising: a frame with an accommodation space inside. It is characterized in that: a U-shaped beam for separating the accommodation space is arranged inside the frame, battery modules are arranged on both sides of the U-shaped beam inside the frame, and a basic component for suppressing thermal runaway is arranged on the side of the U-shaped beam. Through the transverse separation of the internal space of the frame by the U-shaped beam, the isolation of the battery modules on both sides is realized, the structural stability of the frame is improved, and the possibility of the spread of a single-sided fire source is reduced. The basic components arranged on both sides of the U-shaped beam are close to the battery modules, and can play a role in time to block the fire and extinguish the fire when the battery modules accidentally explode and burn, thereby reducing the possibility of a large fire caused by the spread of the fire of the storage battery in the warehouse and improving the safety of use.

[0008] Preferably, through holes are arranged in an array on both sides of the U-shaped beam, and the through holes communicate with the accommodation spaces on both sides of the U-shaped beam. Since not all battery modules generate heat during the use of the storage battery, the heat generated by the battery modules on both sides of the U-shaped beam can flow through the through holes to achieve temperature balance inside the frame, which helps to prevent the battery modules from exploding and burning due to excessive local temperature, and also improves the overall battery life.

[0009] Preferably, a baffle is arranged on the side of the U-shaped beam close to the battery module. The baffle has a first plate body with a gap from the side of the U-shaped beam, and second plate bodies connecting the U-shaped beam are arranged at both ends of the first plate body. A basic component can be arranged on the side of the first plate body close to the battery module. In the prior art, most passively triggered fire extinguishing components are attached to the surface of the battery, which requires prior assembly of the battery pack and the fire extinguishing patch, and then installation into the corresponding protective housing or frame. During the installation process, since the battery needs to be fastened in the housing, there is a possibility that the internal clamping components in the housing scratch the fire extinguishing patch, which is likely to cause damage and leakage of the fire extinguishing patch, and may also cause accidental premature release of the fire extinguishing patch. In the present invention, by arranging the basic component on the first plate body, only the battery module needs to be placed on the other side of the basic component, which improves the assembly efficiency;

[0010] Since through holes are arranged in an array on both sides of the U-shaped beam, the gap between the first plate body and the side of the U-shaped beam ensures the heat dissipation function of the through holes. At the same time, when the battery module accidentally explodes and burns, the basic component on one side of the baffle releases the internal medium under high temperature, so as to extinguish the spark and flame. When the medium is released, it is blocked by the baffle and preferentially released towards the battery module without obstruction, so that the medium first fills the space where the burning battery module is located, forms a quick wrap of the burning battery, and then the medium reversely passes through the through holes to reach the battery module on the opposite side to form a protection, preventing the flame from spreading and causing the combustion and explosion of other battery modules, realizing the directional and rapid release of the medium by the basic component for fire extinguishing, efficiently suppressing thermal runaway, and effectively reducing the possibility of re-ignition after fire extinguishing;

[0011] The first plate body arranged at intervals with the U-shaped beam reduces external vibration interference and the transmission of external heat to the battery module, improving the stability of battery power supply.

[0012] Preferably, the first plate body has a convex plate. The convex plate and the first plate body form a groove with an opening facing the battery module, and the base member covers the groove. The convex plate provides support for the middle part of the first plate body, preventing the first plate body from being overly deformed and broken when installing the battery module. The base member is covered and arranged on the groove on the end face of the first plate body. The groove facilitates the loading and unloading operation of the base member. At the same time, when the medium in the base member is released, the fire extinguishing medium can be released into the groove to form a small amount of accumulation, which can effectively inhibit the heat transfer to the opposite side, thereby protecting the undamaged battery in a timely and effective manner. On the one hand, it suppresses the fire and reduces the fire in the warehouse caused by the spread of the fire. On the other hand, it can recover the normal battery module after extinguishing the fire, reducing the maintenance and replacement cost.

[0013] Preferably, both the first plate body and the second plate body are elastic plates, and the end of the convex plate can contact the U-shaped beam. The first plate body and the second plate body made of elastic material are conducive to the installation of the battery module. Through the deformation of the first plate body and the second plate body, the base member can be well fitted to the battery module, so as to more timely sense the heat change, which is beneficial to the base member to act and extinguish the fire in a timely manner, reducing the disaster loss.

[0014] Preferably, an extension plate is provided above the baffle. The extension plate is located on the U-shaped beam for hanging the baffle. The extension plate is used for the installation and positioning of the baffle, preventing the baffle from falling down when the battery module is assembled in the frame, which is convenient for assembly.

[0015] Preferably, there is a separator in the frame for separating the battery modules on the same side. The setting of the separator reduces the spread speed of the fire to the surrounding batteries after the battery catches fire, alleviating the fire situation.

[0016] Preferably, the separator includes a shell. The shell is arranged in cooperation with the inner wall of the frame, and the shell has a channel that communicates externally on one side. The shell separates the battery modules, which can effectively inhibit the conduction of heat to the normal batteries and inhibit the formation of heat energy transfer to protect the battery pack.

[0017] Preferably, sealing plates are arranged above and below the frame. The sealing plates have grooves that cooperate with the extension plates, and mounting holes for connecting the sealing plates are provided on the upper and lower surfaces of the frame. Fasteners are arranged in the mounting holes for connecting the sealing plates to form a relatively sealed cavity. The tightly installed sealing plates can press the extension plates, thereby stabilizing the position of the baffle. After removing the sealing plates, the baffle can also move freely, improving the loading and unloading efficiency of the battery.

[0018] Preferably, the frame includes opposed vertical plates which are hollow and internally provided with spaced fin plates. The fin plates within the vertical plates are conducive to improving the structural strength of the vertical plates, enhancing the structural strength of the frame when subjected to longitudinal forces. At the same time, the fin plates can also disperse the heat inside, achieve heat dissipation, and reduce the possibility of high-temperature explosion and combustion of the battery.

[0019] The utility model has the following beneficial effects compared with the prior art: The U-shaped beam separates the batteries and uses the through holes to achieve heat dissipation circulation, preventing overheating and combustion; the baffle facilitates the assembly of the battery module and reduces the possibility of battery assembly damage; the baffle can concentrate the fire extinguishing medium released by the base member to one side to achieve directional fire extinguishing, improving the efficiency of suppressing thermal runaway; the baffle can reduce heat transfer and vibration interference, improving the stability of the battery; the convex plate can intercept the fire extinguishing medium, prevent heat transfer from affecting other batteries, and reduce the risk coefficient; the baffle and the U-shaped beam are spaced apart, and on the basis of cooperating with the through holes to achieve heat dissipation, part of the fire extinguishing medium can be released to reach the batteries on the opposite side to form protection; the assembly of the sealing plate on the frame can press the baffle to form an assembly connection, and the baffle can be disassembled by removing the sealing plate, improving the loading and unloading efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0027] First, the concepts involved in this application will be described in conjunction with the accompanying drawings. It should be noted here that the descriptions of the following concepts are only for making the content of this application easier to understand, and do not represent a limitation on the protection scope of this application; at the same time, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Next, this application will be described in detail with reference to the accompanying drawings and in conjunction with the embodiments.

[0028] See the attached Figure 1 - attached Figure 2 , Embodiment 1: A storage battery with a fire extinguishing sticker, comprising: a frame, which has an accommodation space inside, and is characterized in that: a U-shaped beam 2 for partitioning the accommodation space is provided inside the frame, battery modules 3 are arranged on both sides of the U-shaped beam 2 inside the frame, and a base member 4 for suppressing thermal runaway is arranged on the side of the U-shaped beam 2.

[0029] The frame includes, but is not limited to, a rectangular frame body.

[0030] There are at least two groups of battery modules 3 on one side of the U-shaped beam 2. One group of battery modules 3 includes at least two battery blocks. The battery blocks include, but are not limited to, single-cell batteries. The connection method of the two battery blocks in the same group of battery modules 3 includes, but is not limited to, longitudinal stacking.

[0031] The base member 4 includes, but is not limited to, fire extinguishing materials using the following patents: CN114748830A, CN114736554A.

[0032] The present utility model horizontally partitions the internal space of the frame through the U-shaped beam 2 to realize the isolation of the battery modules 3 on both sides, improve the structural stability of the frame and reduce the possibility of the spread of a single-sided fire source. The base member 4 arranged on both sides of the U-shaped beam 2 is close to the battery module 3, and can play a role in time to block the fire and extinguish the fire when the battery module 3 explodes accidentally. Thereby reducing the possibility of a large fire caused by the spread of the fire after the storage battery burns in the warehouse, and improving the safety of use.

[0033] Through holes are arranged in an array on both sides of the U-shaped beam 2, and the through holes connect the accommodation spaces on both sides of the U-shaped beam 2. Since not all battery modules 3 are working and generating heat when the storage battery is in use, the heat generated by the battery modules 3 on both sides of the U-shaped beam 2 can flow through the through holes, achieving temperature balance in the frame, which helps prevent the local temperature of the battery module 3 from being too high and causing explosion, and also improves the overall life of the battery.

[0034] See attached Figure 3 A baffle 5 is provided on the side of the U-shaped beam 2 close to the battery module 3. The baffle 5 has a first plate body 51 spaced apart from the side of the U-shaped beam 2. Both ends of the first plate body 51 have second plate bodies 52 connected to the U-shaped beam 2. A base member 4 can be provided on one side of the first plate body 51 close to the battery module 3.

[0035] The second plate body 52 is a U-shaped bent plate that is easy to deform but not easy to break.

[0036] In the prior art, most passively triggered fire extinguishing parts are attached to the surface of the battery, which requires the battery pack and the fire extinguishing sticker to be assembled in advance and then installed in the corresponding protective shell 61 or frame. During the installation process, since the battery needs to be fastened in the shell 61, it is easy for the internal clamping elements of the shell 61 to scratch the fire extinguishing sticker, which can easily cause the fire extinguishing sticker to be damaged and leaked, and may also cause the fire extinguishing sticker to be accidentally released in advance. The utility model improves the assembly efficiency by arranging the base member 4 on the first plate body 51, and only the battery module 3 needs to be placed on the other side of the base member 4;

[0037] Since through holes are arranged in arrays on both sides of the U-shaped beam 2, the gap between the first plate 51 and the side of the U-shaped beam 2 ensures the heat dissipation function of the through holes. At the same time, when the battery module accidentally explodes, the base member 4 on one side of the baffle 5 releases the internal medium under high temperature, thereby extinguishing the sparks and flames. At the moment of medium release, it is blocked by the baffle 5 and preferentially released in the direction of the unblocked battery module, so that the medium first fills the space where the burning battery module is located, forming a rapid wrapping of the burning battery, and then the medium passes through the through hole in the opposite direction to reach the opposite battery module 3, forming protection to prevent the flame from spreading and causing combustion and explosion of other battery modules 3, thereby realizing the directional and rapid release of the medium by the base member 4 for fire extinguishing, effectively suppressing thermal runaway, and effectively reducing the possibility of re-ignition after fire extinguishing;

[0038] The first plate 51 spaced apart from the U-shaped beam 2 reduces external vibration interference and the transfer of external heat to the battery module 3, thereby improving the battery power supply stability.

[0039] The first plate body 51 has a convex plate 53. The convex plate 53 and the first plate body 51 form a groove with an opening facing the battery module 3, and the base member 4 covers the groove. The setting of the convex plate 53 provides support for the middle part of the first plate body 51, avoiding excessive deformation and fracture of the first plate body 51 when installing the battery module 3. The base member 4 is covered and arranged on the end face of the first plate body 51 on the groove. The groove facilitates the loading and unloading operation of the base member 4. At the same time, when the medium is released in the base member 4, the fire extinguishing medium can be released into the groove to form a small amount of accumulation, which can effectively inhibit the heat transfer to the opposite side, thereby protecting the undamaged battery in a timely and effective manner. On the one hand, it suppresses the fire and reduces the fire in the warehouse caused by the spread of the fire. On the other hand, it can recycle the normal battery module 3 after extinguishing the fire, reducing the maintenance and replacement cost.

[0040] Both the first plate body 51 and the second plate body 52 are elastic plates, and the end of the convex plate 53 can contact the U-shaped beam 2. The first plate body 51 and the second plate body 52 made of elastic material are beneficial to the installation of the battery module 3. Through the deformation of the first plate body 51 and the second plate body 52, the base member 4 can be well attached to the battery module 3, so as to feel the heat change more timely, which is beneficial to the base member 4 to act and extinguish the fire in time, reducing the loss of the disaster.

[0041] An extension plate 54 is provided above the baffle 5. The extension plate 54 is located on the U-shaped beam 2 for hanging the baffle 5. The extension plate 54 is used for the installation and positioning of the baffle 5, preventing the baffle 5 from falling down when the battery module 3 is assembled in the frame, which is convenient for assembly.

[0042] There is a separator 6 in the frame for separating the battery modules 3 on the same side. The setting of the separator 6 reduces the spread speed of the fire to the surrounding batteries after the battery catches fire, and alleviates the fire.

[0043] See attached Figure 4 , the separator 6 includes a housing 61. The housing 61 is arranged in cooperation with the inner wall of the frame. The housing 61 has a through-channel 62, and the plate body is provided with flow ports on both sides. The housing 61 separates the battery modules 3. And when the medium in the base member 4 on one side is released, the medium can enter the channel 62 of the housing 61 on the other side through the through-hole. At this time, the medium in the channel 62 fills to form a homogeneous isolation layer in the housing 61, which can effectively inhibit the conduction of heat to the normal battery and inhibit the heat energy transfer to form battery pack protection.

[0044] The housing 61 is respectively provided with a first hole body 63 and a second hole body 64 on both sides. The first hole body 63 is close to the middle of the frame and adjacent to the U-shaped beam 2. The second hole body 64 is far from the U-shaped beam 2 and close to the frame. The first hole body 63 and the second hole body 64 are communicated with the channel 62.

[0045] The first hole body 63 and the second hole body 64 are arranged in a longitudinal array.

[0046] It should be noted that one end of the channel 62 communicating with the outside is arranged in cooperation with the inner wall of the frame, and one end of the housing 61 close to the U-shaped beam 2 is closed.

[0047] When the battery module 3 in the middle of the frame explodes and burns, the base member 4 is heated to release the internal medium. The medium can fill and surround the outside of the burning battery module 3. At the same time, the medium can enter the channel 62 of the housing 61 through the first hole body 63 close to the U-shaped beam 2, and fill in the channel 62 to form a uniform medium isolation layer, so as to form a large-range heat insulation, further reduce the damage of the surrounding batteries, protect the battery module 3, while reducing the excessive diffusion and adhesion of the medium on the non-faulty batteries, facilitating the recycling of the battery pack and reducing the recycling and cleaning difficulty.

[0048] Since the battery module 3 close to the middle of the frame has a stronger ability to transfer flame and heat to the surrounding after explosion and combustion, the first hole body 63 close to the U-shaped beam 2 is arranged at a position close to the center of the frame of the housing 61, and the second hole body 64 is arranged at a position of the housing 61 far from the center of the frame 1 and close to the inner wall of the frame 1.

[0049] Sealing plates 7 are arranged above and below the frame 1. The sealing plates 7 have grooves for cooperating with the extension plates 54. Mounting holes 11 for connecting the sealing plates 7 are arranged on the upper and lower surfaces of the frame 1. Fasteners are arranged in the mounting holes 11 for connecting the sealing plates 7 to the frame 1 to form a relatively sealed cavity. The tightly installed sealing plates 7 can press the extension plates 54, so as to stabilize the position of the baffle 5. After the sealing plates 7 are disassembled, the baffle 5 can also move freely, improving the loading and unloading efficiency of the battery.

[0050] The frame 1 includes opposite vertical plates 12. The vertical plates 12 are hollow and internally provided with spaced wing plates 13. The wing plates 13 in the vertical plates 12 are beneficial to improving the structural strength of the vertical plates 12, improving the structural strength of the frame 1 when bearing longitudinal force. At the same time, the wing plates 13 can also disperse the heat inside, realizing heat dissipation and reducing the possibility of high-temperature explosion of the battery.

[0051] Embodiment 2: On the basis of Embodiment 1 of the present utility model, the partition can also be arranged at the inner edge of the frame, between the battery module and the frame. At this time, the extension plate is located on the upper end surface of the frame, and a base member can also be arranged on one side of the partition close to the battery module.

[0052] The above scheme forms a fire prevention layout between the frame and the battery module. When the outside of the frame is overheated, the heat is transferred to the base member, which can cause the base member to release the medium to protect the battery, so as to prevent the external fire source from affecting the internal battery module through the frame.

[0053] The arrangement of the partition and the base member on the outside of the battery module also forms a pile foundation protection, reducing the possibility of the battery module exploding due to excessive pressure.

Any person skilled in the art, without departing from the scope of the technical means disclosed in the content of the present utility model, may make some modifications or changes to other equivalent embodiments, but should still be regarded as the same technology or embodiment as the present utility model in essence.

The above is only the preferred implementation manner of the present application.
