Description

Technical Field

[0001] The present application relates to the field of automobile technology, and in particular to a battery and a vehicle. Background Art

[0002] With the rise and popularization of new energy vehicles, the development of electric vehicles is particularly rapid. Electric vehicles use electricity as a power source and replace fuel engines with electric motors. They not only have the characteristics of high efficiency, low noise, and reduced exhaust emissions, but also can save a lot of fuel energy.

[0003] At present, the safety of electric vehicles has become a key concern in the industry, especially battery thermal runaway accidents. When a single battery cell of an electric vehicle battery experiences thermal runaway, the high-temperature gas ejected from the battery cell will damage the battery case cover. If it is not discharged in time, it will easily spread to other normal battery cells, causing heat diffusion and damage to other normal battery cells. As the core power component of electric vehicles, the structural safety of the power battery pack is an important factor affecting the safety factor of the entire vehicle.

[0004] In the existing battery pack structure, the bottom guard plate of the battery pack box is usually composed of an ordinary sheet metal structure, which is a one-piece structure with reinforcing ribs. The cylindrical battery cell explosion-proof valve is located at the bottom of the battery cell. It is necessary to design a sufficient pressure relief channel at the bottom of the battery box to ensure the stability and safety of the power battery.

[0005] Therefore, the lack of space for the pressure relief channel at the bottom of the battery box is an urgent problem to be solved. Utility Model Content

[0006] The present application provides a battery and a vehicle for solving problems such as insufficient space for a pressure relief channel at the bottom of a battery box.

[0007] According to a first aspect of the present application, there is provided a battery, comprising: a shell, a plurality of battery cells and a second explosion-proof valve, wherein a storage chamber is provided in the shell, and an opening is provided on the shell, wherein the opening connects the storage chamber with an external space; the plurality of battery cells are arranged in the storage chamber; any battery cell comprises: a core body and a first explosion-proof valve, wherein the first explosion-proof valve is used to relieve pressure on the core body; the second explosion-proof valve is arranged at the opening, wherein the second explosion-proof valve is used to relieve pressure on the shell; the shell comprises: a bottom plate, wherein a plurality of protrusions are formed on the bottom plate, wherein the plurality of battery cells are arranged on the protrusions; a first channel is formed between any adjacent protrusions, wherein the plurality of first explosion-proof valves are arranged toward the first channel and can be communicated with the first channel; and the second explosion-proof valve is communicated with the first channel.

[0008] In this way, when one of the cells in the battery has a thermal runaway, the high-temperature gas ejected from the battery cell will be discharged from the first explosion-proof valve, reducing the pressure inside the cell. The first channel connects the first explosion-proof valve and the second explosion-proof valve, and the high-temperature gas can be depressurized by the first channel and then discharged to the external space through the second explosion-proof valve, thereby reducing the pressure inside the battery. The first explosion-proof valve is arranged toward the first channel, and the high-temperature gas discharged from the explosion-proof valve can be guided to the second explosion-proof valve at the first time, thereby preventing the high-temperature gas from existing inside the battery for too long, affecting other cells and causing heat diffusion, thereby improving the safety of the battery.

[0009] In some embodiments of the present application, a plurality of rows of protrusions are arranged on the bottom plate, and any row of the plurality of rows of protrusions includes a plurality of protrusions.

[0010] In this way, a first channel is formed between the plurality of protrusions, so that the high-temperature gas discharged from different battery cells can be discharged in different directions, thereby preventing the high-temperature gas from gathering in one place, thereby causing damage to the place.

[0011] In some embodiments of the present application, the multiple rows of protrusions include: a first row of protrusions and a second row of protrusions adjacent to the first row of protrusions, and the multiple protrusions in the first row of protrusions and the multiple protrusions in the second row of protrusions are staggered along a first direction, and the first direction is perpendicular to the arrangement direction of the multiple rows of protrusions.

[0012] In this way, the multiple protrusions in the first row of protrusions and the multiple protrusions in the second row of protrusions are staggered along the first direction, so that the first channel can extend in different directions, and the high-temperature gas discharged from overheated different battery cells can be discharged along the first channels at different positions, which can prevent the high-temperature gas discharged from the first explosion-proof valves of different battery cells from leaking along the first channel at the same position, causing damage to the first channel at that position and affecting the normal use of the battery.

[0013] In some embodiments of the present application, the bottom plate further includes: a bottom guard plate and a bending plate, the bending plate is arranged on the bottom guard plate, and the bottom guard plate is located on a side of the bending plate away from the battery cell, and a protrusion is formed on the bending plate.

[0014] In this way, setting the bottom guard plate on the side of the bending plate away from the battery cell can make the first channel close to the battery cell. When the battery cell has thermal runaway, the high-temperature gas discharged from the first explosion-proof valve can be released faster. Moreover, part of the impact force received by the bottom guard plate can also be transmitted to the bending plate, further improving the overall strength of the bottom plate.

[0015] In some embodiments of the present application, the bending plate includes: a first connecting plate, a first extension plate and a support plate, the first connecting plate is connected to the bottom guard plate; one end of the first extension plate is connected to the first connecting plate, and the other end of the first extension plate extends to a side away from the bottom guard plate; the support plate is connected to the first extension plate and is spaced apart from the bottom guard plate, and the battery cell is arranged on the support plate.

[0016] It can be understood that the support plate can support the battery cell so that there is a gap between the battery cell and the bottom guard plate. When the battery cell has thermal runaway, the high-temperature gas discharged from the first explosion-proof valve can leak out from the gap between the battery cell and the bottom guard plate, thereby increasing the pressure relief channel of the high-temperature gas and further improving the pressure relief capacity of the battery.

[0017] In some embodiments of the present application, the bending plate also includes: a second connecting plate connected to the bottom guard plate; a second extension plate, one end of which is connected to the second connecting plate, and the other end of which extends to a side away from the bottom guard plate and is connected to the support plate.

[0018] In this way, setting up the second connecting plate and the second extension plate can improve the overall strength of the bending plate, which can not only improve the impact resistance of the bottom plate, but also improve the supporting force of the protrusion, thereby preventing the battery cell from shaking or dislocating due to insufficient supporting force of the protrusion, resulting in the battery being unable to be used normally.

[0019] In some embodiments of the present application, the first extension plate and the second extension plate are spaced apart from each other so as to form a second channel therebetween, and the second channel is connected to the first channel.

[0020] In this way, the second channel can guide the high-temperature gas discharged from the first explosion-proof valve to the second explosion-proof valve together with the first channel, and then discharge it to the external space of the battery, thereby improving the pressure relief capacity of the battery.

[0021] In some embodiments of the present application, the shell further includes: a top plate and a frame; the top plate and the bottom plate are respectively arranged on opposite sides of the frame, and the top plate and the bottom plate are both connected to the frame, the top plate, the bottom plate and the frame enclose a accommodating chamber, and the second explosion-proof valve is arranged on the frame.

[0022] It can be understood that the accommodating chamber enclosed by the top plate, the bottom plate and the frame can protect the battery cells and prevent the battery cells from being affected by external factors. Compared with setting the explosion-proof valve on the top plate or the bottom plate, setting the second explosion-proof valve on the frame can prevent other components installed near the bottom plate or the top plate from affecting the pressure release of the battery.

[0023] In some embodiments of the present application, it also includes: a first bracket and a second bracket, which are arranged on a side of the bottom plate close to the battery cell, and the first bracket is connected to the bottom plate; a second bracket is arranged on a side of the top plate close to the battery cell, and the second bracket is connected to the top plate; the first bracket and the second bracket both include: a plurality of limiting holes, the limiting holes are arranged corresponding to the battery cells, and the battery cells at least partially extend into the limiting holes so that the limiting holes limit the battery cells.

[0024] In this way, the multiple limiting holes of the first bracket and the second bracket can limit the battery cells to prevent the battery cells from shaking or falling off, thereby causing damage to the battery cells and making the battery unable to work normally, thereby improving the stability of the battery cells.

[0025] A second aspect of the present application provides a vehicle, comprising: the above-mentioned battery.

[0026] Since the vehicle provided in the embodiment of the present application includes the battery as described in the first aspect above, the two can solve the same problem and achieve the same effect, and the present application will not elaborate on them one by one here.

[0027] Therefore, the above technical features of the present application have the following beneficial effects:

[0028] (1) When a battery cell in the battery experiences thermal runaway, the high-temperature gas ejected from the battery cell will be discharged from the first explosion-proof valve. The first channel connects the first explosion-proof valve and the second explosion-proof valve. The high-temperature gas can be depressurized by the first channel and then discharged to the outside space through the second explosion-proof valve. The first explosion-proof valve is arranged toward the first channel, and the high-temperature gas discharged from the explosion-proof valve can be guided to the second explosion-proof valve as soon as possible, thereby preventing the high-temperature gas from existing in the battery for too long and affecting other battery cells, causing heat diffusion, and improving the safety of the battery.

[0029] (2) The plurality of protrusions in the first row of protrusions and the plurality of protrusions in the second row of protrusions are staggered along the first direction, so that the first channel can extend in different directions. High-temperature gases discharged from overheated battery cells can be discharged along first channels at different positions, thereby preventing high-temperature gases discharged from first explosion-proof valves of different battery cells from leaking along the first channel at the same position, causing damage to the first channel at that position.

[0030] (3) The second channel can guide the high-temperature gas discharged from the first explosion-proof valve to the second explosion-proof valve together with the first channel, and then discharge it to the external space of the battery, thereby improving the pressure relief capacity of the battery.

[0031] (4) The multiple limiting holes of the first bracket and the second bracket can limit the battery cells to prevent the battery cells from shaking or falling off, thereby causing damage to the battery cells and making the battery unable to work normally, thereby improving the stability of the battery cells.

[0038] In order to enable ordinary persons in the art to better understand the technical solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0039] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0040] With the rise and popularity of new energy vehicles, electric vehicle safety issues have become a key concern in the industry, especially battery thermal runaway accidents. When a single battery cell of an electric vehicle battery experiences thermal runaway, the high-temperature gas emitted by the battery cell will damage the upper cover of the battery box. If it is not discharged in time, it is easy to spread to other normal battery cells, causing heat diffusion and damage to other normal battery cells. Therefore, it is necessary to design sufficient pressure relief channels at the bottom of the battery box to ensure the stability and safety of the power battery.

[0041] In a first aspect, the present application provides a battery 100, such as Figure 1 and Figure 2As shown, it includes: a shell 10, a plurality of battery cells 20 and a second explosion-proof valve 11, a storage chamber is opened in the shell 10, and an opening is opened on the shell 10, and the opening connects the storage chamber with the external space; the plurality of battery cells 20 are arranged in the storage chamber; any battery cell 20 includes: a core body 21 and a first explosion-proof valve 22, and the first explosion-proof valve 22 is used to release the pressure of the core body 21; the second explosion-proof valve 11 is arranged at the opening, and the second explosion-proof valve 11 is used to release the pressure of the shell 10; the shell 10 includes: a bottom plate 30, a plurality of protrusions 31 are formed on the bottom plate 30, and the plurality of battery cells 20 are arranged on the protrusions 31; a first channel 40 is formed between any adjacent protrusions 31, and the plurality of first explosion-proof valves 22 are arranged toward the first channel 40 and can be communicated with the first channel 40; the second explosion-proof valve 11 is communicated with the first channel 40.

[0042] The material of the housing 10 may be metal, ceramic or plastic, etc., which is not limited in the present application.

[0043] The battery cell 20 may be a lithium battery cell 20 or a lead-acid battery cell 20 , etc., which is not limited in the present application.

[0044] It should be noted that the battery 100 is filled with large amounts of chemical substances, and a large amount of mixed gas and liquid will be generated during the charging and discharging process, accompanied by the continuous accumulation of pressure. If these pressures are not balanced or released in time, the shell will deform and leak, and in more serious cases, the battery 100 will explode. The explosion-proof valve can quickly ventilate and release pressure, and prevent explosion, solving the problem of excessive pressure in the new energy vehicle battery 100. The first explosion-proof valve 22 and the second explosion-proof valve 11 in this application can use direct-acting solenoid valves, distributed direct-acting solenoid valves or pilot solenoid valves, and this application does not limit this.

[0045] In addition, multiple protrusions 31 can be arranged in an array with uniform intervals, or can be arranged irregularly. A single protrusion 31 can support a battery cell 20, or two or more protrusions 31 can support a battery cell 20. Multiple battery cells 20 can also share one protrusion 31, and this application does not limit this.

[0046] In addition, the first channel 40 may be a gap between adjacent protrusions 31 , or may be a pipe or hole that are interconnected, etc., which is not limited in the present application.

[0047] In this way, when one of the cells 20 in the battery 100 experiences thermal runaway, the high-temperature gas ejected from the cell 20 of the battery 100 will be discharged from the first explosion-proof valve 22, thereby reducing the internal pressure of the cell 20. The first channel 40 connects the first explosion-proof valve 22 and the second explosion-proof valve 11, and the high-temperature gas can be depressurized by the first channel 40 and then discharged to the external space through the second explosion-proof valve 11, thereby reducing the internal pressure of the battery 100. The first explosion-proof valve 22 is arranged toward the first channel 40, and the high-temperature gas discharged from the explosion-proof valve can be guided to the second explosion-proof valve 11 at the first time, thereby preventing the high-temperature gas from existing in the battery 100 for too long, affecting other cells 20, causing heat diffusion, and improving the safety of the battery 100.

[0048] In some embodiments of the present application, Figure 2 and Figure 3 As shown, a plurality of rows of protrusions 31 are disposed on the bottom plate 30 , and any row of protrusions 31 in the plurality of rows of protrusions 31 includes a plurality of protrusions 31 .

[0049] The number of protrusions 31 included in each row may be the same or different, and this application does not limit this.

[0050] In this way, the first channels 40 are formed between the plurality of protrusions 31 , so that the high-temperature gases discharged from different battery cells 20 can be discharged in different directions, thereby preventing the high-temperature gases from gathering in one place and causing damage thereto.

[0051] In some embodiments of the present application, Figure 2 and Figure 3 As shown, the multiple rows of protrusions 31 include: a first row of protrusions 311 and a second row of protrusions 312 adjacent to the first row of protrusions 311, and the multiple protrusions 31 in the first row of protrusions 311 and the multiple protrusions 31 in the second row of protrusions 312 are staggered along a first direction, and the first direction is perpendicular to the arrangement direction of the multiple rows of protrusions 31.

[0052] In this way, the multiple protrusions 31 in the first row of protrusions 311 and the multiple protrusions 31 in the second row of protrusions 312 are staggered along the first direction, so that the first channel 40 can extend in different directions, and the high-temperature gas discharged from overheated different battery cells 20 can be discharged along the first channels 40 at different positions, which can prevent the high-temperature gas discharged from the first explosion-proof valves 22 of different battery cells 20 from leaking along the first channel 40 at the same position, causing damage to the first channel 40 at that position and affecting the normal use of the battery 100.

[0053] In a possible structural design, multiple rows of battery cells 20 are arranged on the bottom plate 30, and the multiple rows of battery cells 20 include: a first row of battery cells 20 and a second row of battery cells 20 adjacent to the first row of battery cells 20, the multiple battery cells 20 are arranged at intervals in the first direction, the first row of battery cells 20 are arranged corresponding to the first row of protrusions 311, and the first explosion-proof valves 22 of the multiple battery cells 20 of the first row of battery cells 20 are arranged in the first channel 40 between the adjacent protrusions 31 of the first row of protrusions 311, and the first explosion-proof valves 22 are connected to the first channel 40.

[0054] In some embodiments of the present application, Figure 1 and Figure 4 As shown, the bottom plate 30 further includes: a bottom guard plate 32 and a bending plate 33 . The bending plate 33 is disposed on the bottom guard plate 32 , and the bottom guard plate 32 is located on a side of the bending plate 33 away from the battery cell 20 . A protrusion 31 is formed on the bending plate 33 .

[0055] The bending plate 33 protrudes toward one side of the battery core 20 , and the height of the protrusion 31 may be greater than or equal to the length of the first explosion-proof valve 22 , which is not limited in the present application.

[0056] In this way, by setting the bottom guard plate 32 on the side of the bending plate 33 away from the battery cell 20, the first channel 40 can be close to the battery cell 20. When the battery cell 20 has thermal runaway, the high-temperature gas discharged from the first explosion-proof valve 22 can be released faster. Moreover, part of the impact force exerted on the bottom guard plate 32 can also be transmitted to the bending plate 33, so that the bending plate 33 can bear the external force together with the bottom guard plate 32, thereby further improving the overall strength of the bottom plate 30.

[0057] In some embodiments of the present application, Figure 1 and Figure 4 As shown, the bending plate 33 includes: a first connecting plate 331, a first extension plate 332 and a support plate 333, the first connecting plate 331 is connected to the bottom guard plate 32; one end of the first extension plate 332 is connected to the first connecting plate 331, and the other end of the first extension plate 332 extends to a side away from the bottom guard plate 32; the support plate 333 is connected to the first extension plate 332, and is spaced apart from the bottom guard plate 32, and the battery cell 20 is arranged on the support plate 333.

[0058] The first connecting plate 331 and the bottom guard plate 32 may be connected by welding, bolting or riveting, etc., which is not limited in the present application.

[0059] In addition, the connection method between the first extension plate 332 and the first connection plate 331 and the connection method between the first extension plate 332 and the support plate 333 are the same as described above, and are not described in detail in this application.

[0060] It can be understood that the support plate 333 can support the battery cell 20 so that there is a gap between the battery cell 20 and the bottom guard plate 32. When the battery cell 20 has thermal runaway, the high-temperature gas discharged from the first explosion-proof valve 22 can leak out from the gap between the battery cell 20 and the bottom guard plate 32, thereby increasing the pressure relief channel of the high-temperature gas and further improving the pressure relief capacity of the battery 100.

[0061] In some embodiments of the present application, Figure 1 and Figure 4 As shown, the bending plate 33 also includes: a second connecting plate 334 connected to the bottom guard plate 32; a second extension plate 335, one end of which is connected to the second connecting plate 334, and the other end extends to a side away from the bottom guard plate 32 and is connected to the support plate 333.

[0062] In this way, providing the second connecting plate 334 and the second extension plate 335 can improve the overall strength of the bending plate 33, which can not only improve the impact resistance of the bottom plate 30, but also improve the supporting force of the protrusion 31, thereby preventing the battery cell 20 from shaking or dislocating due to insufficient supporting force of the protrusion 31, resulting in the battery 100 being unable to be used normally.

[0063] In a possible structural design, the first connecting plate 331 , the second connecting plate 334 , the first extending plate 332 , the second extending plate 335 and the supporting plate 333 are an integrated structure.

[0064] In this way, the bending plate 33 is set as an integrated structure. Compared with the connection method of welding or bolting the first connecting plate 331, the second connecting plate 334, the first extension plate 332, the second extension plate 335 and the support plate 333, it can avoid the bending plate 33 from breaking at the connection point, thereby improving the overall strength of the bending plate 33.

[0065] In some embodiments of the present application, Figure 3 and Figure 4 As shown, the first extension plate 332 and the second extension plate 335 are spaced apart from each other to form a second channel 50 therebetween, and the second channel 50 is communicated with the first channel 40 .

[0066] In this way, the second channel 50 and the first channel 40 can guide the high-temperature gas discharged from the first explosion-proof valve 22 to the second explosion-proof valve 11 and then to the external space of the battery 100 , thereby improving the pressure relief capacity of the battery 100 .

[0067] In a possible structural design, the first explosion-proof valve 22 is disposed close to one end of the second channel 50 .

[0068] In this way, the high-temperature gas discharged from the first explosion-proof valve 22 can be quickly discharged through the adjacent second channel 50, avoiding the accumulation of high-temperature gas in the accommodation space, causing damage to the inside of the battery 100, and improving the pressure relief capacity of the battery 100.

[0069] In some embodiments of the present application, Figure 1 and Figure 5 As shown, the shell 10 also includes: a top plate 12 and a frame 13; the top plate 12 and the bottom plate 30 are respectively arranged on opposite sides of the frame 13, and the top plate 12 and the bottom plate 30 are both connected to the frame 13, the top plate 12, the bottom plate 30 and the frame 13 enclose a containing chamber, and the second explosion-proof valve 11 is arranged on the frame 13.

[0070] Among them, a plurality of second explosion-proof valves 11 may be arranged on the frame 13, and the plurality of second explosion-proof valves 11 are arranged at intervals, which is not limited in the present application.

[0071] It can be understood that the accommodating chamber enclosed by the top plate 12, the bottom plate 30 and the frame 13 can protect the battery cell 20 and prevent the battery cell 20 from being affected by external factors. Compared with setting the explosion-proof valve on the top plate 12 or the bottom plate 30, setting the second explosion-proof valve 11 on the frame 13 can prevent other components installed near the bottom plate 30 or the top plate 12 from affecting the pressure release of the battery 100.

[0072] In some embodiments of the present application, Figure 1 and Figure 5 As shown, it also includes: a first bracket and a second bracket 60, which are arranged on the side of the bottom plate 30 close to the battery cell 20, and the first bracket is connected to the bottom plate 30; the second bracket 60 is arranged on the side of the top plate 12 close to the battery cell 20, and the second bracket 60 is connected to the top plate 12; the first bracket and the second bracket 60 both include: a plurality of limiting holes, the limiting holes are arranged corresponding to the battery cell 20, and the battery cell 20 at least partially extends into the limiting holes so that the limiting holes limit the battery cell 20.

[0073] In this way, the multiple limiting holes of the first bracket and the second bracket 60 can limit the battery cell 20 to prevent the battery cell 20 from shaking or falling off, thereby causing damage to the battery cell 20 and making the battery 100 unable to work normally, thereby improving the stability of the battery cell 20.

[0074] In a possible structural design, the first bracket and the second bracket 60 are connected.

[0075] In this way, the first bracket and the second bracket 60 can be made more stable, thereby preventing the battery cell 20 from falling off after being subjected to external force, causing the battery 100 to fail to work normally.

[0076] A second aspect of the present application provides a vehicle, comprising: the above-mentioned battery 100.

[0077] Since the vehicle provided in the embodiment of the present application includes the battery 100 as described in the first aspect above, the two can solve the same problem and achieve the same effect, and the present application will not elaborate on them one by one here.

[0078] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto, and any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
