[0061] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0062] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0063] Unless otherwise specifically stated, the relative arrangement of the parts and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present application. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to actual proportional relationships. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values should be interpreted as being merely exemplary, not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0064] If the safety performance of battery products is still insufficient, it may affect the normal power supply to electrical equipment, and may even damage electrical equipment due to dangers such as fire and explosion caused by battery products. For example, when the positive and negative poles of the battery are exposed to the outside of the battery, the operator may touch the positive and negative poles of the battery due to improper operation when installing the battery or performing equipment maintenance on the battery, which will cause unnecessary safety hazards to the battery. For example, in order to check the battery power or performance, the operator may use a test instrument (such as a multimeter) to directly touch the positive and negative poles of the battery. Improper operation may cause a short circuit, thereby affecting the power supply to the electrical equipment. Moreover, when a battery short circuit occurs, a huge current will be generated inside the battery, causing the battery temperature to rise rapidly. The high temperature generated will cause dangers such as fire and explosion.

[0065] In order to further improve the safety performance of battery products, the first embodiment of the present invention provides a battery installation device, which includes a cover plate 10, an insulating connection assembly 20 and a short-circuit protection assembly 30. Among them, the insulating connection assembly 20 includes a positive insulating connector and a negative insulating connector, which are installed on the cover plate 10 and spaced apart from each other. The positive insulating connector is at least used to electrically connect the positive pole tab of the battery cell module in the battery to the external power circuit, and the negative insulating connector is at least used to electrically connect the negative pole tab of the battery cell module in the battery to the external power circuit. After the cover plate 10 is connected to the battery shell, the cover plate 10 can also cover the battery cell module and its positive and negative poles arranged in the battery shell. As a result, when the operator performs maintenance and inspection on the battery, it is not easy to touch the positive and negative poles of the battery, and will not cause unnecessary safety hazards to the battery, thereby improving the safety of the battery product.

[0066] Secondly, the short-circuit protection assembly 30 is mounted on the cover plate 10 and electrically connected to the negative electrode insulating connector. Since the positive and negative electrodes of the battery cell module are connected in series, this embodiment electrically connects the short-circuit protection assembly 30 to the negative electrode insulating connector to ensure that the short-circuit protection assembly 30 is always located between the positive and negative electrode tabs of the battery cell module. After a short circuit occurs in the battery cell module, the short-circuit protection assembly 30 can promptly implement short-circuit protection to disconnect the electrical connection between the battery and the external power circuit, thereby ensuring the safety of battery maintenance work and related operators, and further improving the safety performance of the battery.

[0067] It can be seen that the battery installation device provided in this embodiment includes a cover plate 10, an insulating connection assembly 20 and a short-circuit protection assembly 30. The insulating connection assembly 20 includes a positive insulating connector and a negative insulating connector. The positive insulating connector and the negative insulating connector are installed on the cover plate 10 and are spaced apart from each other. Thus, after the cover plate 10 is connected to the battery shell and the positive insulating connector and the negative insulating connector are electrically connected to the positive and negative poles of the battery cell module in the shell, the positive and negative poles of the battery cell module are covered in the shell by the cover plate 10, and the battery cell module is electrically connected to the external power circuit by the insulating connection assembly 20. Such a structure can prevent the operator from touching the positive and negative poles of the battery due to improper operation, thereby improving the safety performance of the battery product. At the same time, since the cover plate 10 is also provided with a short-circuit protection assembly 30 electrically connected to the negative insulating connector, when a short circuit occurs in the battery, the short-circuit protection assembly 30 can quickly disconnect the battery from the external power circuit to make the battery product safer.

[0068] In this embodiment, along the first direction (such as Figure 1The cover plate 10 includes a first side 11 and a second side 12, and at least one of the positive and negative insulating connectors includes a first connecting member 21 and a second connecting member 22. The first connecting member 21 is mounted on the first side 11 and at least partially extends through the second side 12. The second connecting member 22 is located on the second side 12 and is electrically connected to one end of the first connecting member 21 extending through the second side 12. The end of the second connecting member 22, which is away from the first connecting member 21, is used to electrically connect to the positive and / or negative tabs of the battery cell module. Thus, in this embodiment, the positive and negative electrodes of the battery cell module can be electrically connected through the second connecting component 22 located on the second side 12 of the cover plate 10, and electrically connected to the external power circuit through the first connecting component 21 on the first side 11 of the cover plate 10. After the cover plate 10 is connected to the battery housing, the positive and negative electrodes of the battery cell module can be electrically connected to the external power circuit through the first connecting component 21. At the same time, because the positive and negative electrodes of the battery cell module are electrically connected to the second connecting portion 32 on the second side 12 of the cover plate 10, the cover plate 10 can cover the positive and negative electrodes of the battery cell module to isolate the positive and negative electrodes from the external environment. When the operator is performing maintenance and repair on the battery, it is not easy to touch the positive and negative electrodes of the battery cell module, thereby improving the safety of the battery.

[0069] Along the first direction, a first mounting hole 13 is provided through the cover plate 10. In this embodiment, the first connecting component 21 includes a terminal 211 and a terminal socket 212. The terminal socket 212 is mounted on the first side 11 and removably plugged into the terminal 211. The end of the terminal socket 212 away from the terminal 211 is extended along the first mounting hole 13 to the second side 12 and electrically connected to the second connecting component 22. In this embodiment, by removably plugging the terminal 211 into the terminal socket 212, and by installing the terminal socket 212 on the cover plate 10 and extending the end away from the terminal 211 along the first mounting hole 13 to the second side 12 to electrically connect to the second connecting component 22, installation is convenient and quick, which can improve the assembly efficiency of the first connecting component 21, the cover plate 10, and the second connecting component 22.

[0070] A second mounting hole 14 is also provided through the cover plate 10 along the first direction. The short-circuit protection assembly 30 in this embodiment includes a short-circuit protection body 31 and a connecting portion 32. The short-circuit protection body 31 is mounted on the first side 11 and at least partially covers the second mounting hole 14. A fuse is disposed within the short-circuit protection body 31. When a short circuit occurs in the battery's internal circuit, the fuse automatically blows, disconnecting the battery from the external power circuit. The fuse in this embodiment may specifically include a fuse. The connecting portion 32 is disposed on a side of the short-circuit protection body 31 near the second mounting hole 14 and is electrically connected to the fuse. The connecting portion 32 extends at least partially along the second mounting hole 14 to the second side 12 and electrically connects to the second connecting member 22 of the negative electrode insulating connector, thereby connecting the fuse in series between the positive and negative electrodes of the battery. When a short circuit occurs in the battery, the fuse immediately disconnects the connection circuit between the positive and negative electrodes, thereby disconnecting the battery from the external power circuit. The short-circuit protection assembly 30 is electrically connected to the second connecting component 22 of the negative insulating connector through the connecting portion 32 passing through the second mounting hole 14 of the cover plate 10. After the cover plate 10 is connected to the battery shell, the short-circuit protection body 31 of the short-circuit protection assembly 30 will not occupy a large installation space inside the battery, and the connection between the short-circuit protection assembly 30 and the second connecting component 22 is also more efficient and convenient.

[0071] The short-circuit protection body 31 in this embodiment includes a first connector 311 and a second connector 312. The first connector 311 is mounted on the first side 11 and at least partially covers the second mounting hole 14. The connecting portion 32 is disposed on a side of the first connector 311 proximal to the second mounting hole 14. The second connector 312 is removably plugged into the side of the first connector 311 facing away from the cover 10. The fuse is disposed within the second connector 312. Because the fuse is disposed within the second connector 312 and is removably plugged into the first connector 311, when the battery is being repaired, the second connector 312 can be separated from the first connector 311 to disconnect the connection circuit between the positive and negative tabs of the battery, thereby disconnecting the battery from the external power circuit. This ensures the personal safety of the operator, prevents high-voltage electric shock accidents, and achieves electrical isolation between the battery and the external power circuit.

[0072] Specifically, the first connector 311 in this embodiment includes an MSD socket, and the second connector 312 includes an MSD plug. The MSD in the MSD socket and the MSD plug is the English abbreviation for Manual Service Disconnect, and the full Chinese name is Manual Service Disconnect. The structure in which the MSD socket and the MSD plug are plugged in is a high-voltage connector. The high-voltage connector composed of the MSD socket and the MSD plug can be widely used in various battery products, reducing the design difficulty of the short-circuit protection component 30. When the fuse is specifically set in the MSD plug, after the MSD plug is separated from the MSD socket, the connection circuit between the positive and negative poles of the battery can be disconnected, thereby disconnecting the battery from the external power circuit, thereby ensuring the personal safety of the operator, avoiding high-voltage electric shock accidents, and achieving electrical isolation between the battery and the external power circuit.

[0073] In this embodiment, the first connecting component 21 includes a positive connecting component 213, which is a positive electrode insulating connector, and a negative connecting component 214, which is a negative electrode insulating connector. The connecting portion 32 includes a first connecting post 321 and a second connecting post 322, with a fuse connected in series between the first connecting post 321 and the second connecting post 322. The second connecting component 22 includes a first busbar 221, a second busbar 222, and a third busbar 223. One end of the first busbar 221 is electrically connected to the negative electrode connecting component 214. The end of the first busbar 221 away from the negative electrode connecting component 214 is electrically connected to the first connecting post 321. The second busbar 222 is electrically connected to the second connecting post 322. The third busbar 223 is electrically connected to the positive electrode connecting component 213. After the cover plate 10 is connected to the battery housing, the end of the second busbar 222 away from the second connecting column 322 will be electrically connected to the negative electrode tab of the battery cell module in the housing, and the third busbar 223 will be electrically connected to the positive electrode tab of the battery cell module. In this way, the short-circuit protection component 30 is electrically connected between the positive and negative electrode tabs of the battery cell module. After a short circuit occurs in the battery cell module, the connection circuit between the positive and negative electrode tabs can be disconnected by the short-circuit protection component 30, thereby disconnecting the battery from the external power circuit. In this embodiment, the first busbar 221, the second busbar 222, and the third busbar 223 can all include copper bars.

[0074] Among them, the first connecting column 321 and the second connecting column 322 are preferably threaded columns, and corresponding avoidance holes 224 can be set on the end of the first bus 221 away from the negative electrode connecting component 214 and the second bus 222. After the threaded column is passed through the avoidance hole 224, the nut 225 is screwed onto the threaded column to connect the first bus 221 and the second bus 222 to the connecting part 32 conveniently, quickly, stably and reliably.

[0075] The battery mounting device of this embodiment further includes a firefighting assembly 40, which is disposed on the cover plate 10 and offset from the insulating connection assembly 20 and the short-circuit protection assembly 30. The firefighting assembly 40 is configured to spray a fire extinguishing agent onto the second side 12. Since the second side 12 of the cover plate 10 faces the interior of the battery after it is connected to the housing, if a fire occurs in the battery cell module, the firefighting assembly 40 can promptly spray the fire extinguishing agent onto the second side 12 for timely and effective fire extinguishing, preventing the fire from spreading and potentially causing safety accidents (such as explosions), thereby improving the safety of the battery product.

[0076] The battery mounting device also includes a sealing ring 50, which is disposed around the edge of the cover plate 10. Thus, after the cover plate 10 is connected to the battery housing, the sealing ring 50 can seal the installation gap between the cover plate 10 and the housing, thereby preventing external contaminants from entering the battery through the installation gap between the cover plate 10 and the housing, causing contamination or even damage to the battery. The sealing ring 50 is preferably a foamed silicone sealing ring 50, which can maintain excellent physical and chemical properties in high and low temperature environments, and has anti-aging and chemical corrosion properties. It has excellent durability and can extend the service life of the battery product.

[0077] The cover plate 10 is further provided with a third mounting hole 15 extending along the first direction. The firefighting assembly 40 provided in this embodiment includes an atomizing nozzle 41 and a firefighting interface 42. The atomizing nozzle 41 is mounted on the first side 11 and extends at least partially along the third mounting hole 15 to the second side 12. The atomizing nozzle 41 includes a nozzle 411, which is located on the second side 12. After the cover plate 10 is connected to the battery housing, the second side 12 of the cover plate 10 is located inside the battery. The firefighting interface 42 is located on the first side 11 and is detachably connected to the atomizing nozzle 41. Once the fire-fighting interface 42 is connected to the fire-extinguishing agent supply equipment, the fire-extinguishing agent can be sprayed onto the second side 12 through the nozzle 411 of the atomizing nozzle 41. The fire-extinguishing agent is then sprayed into the battery housing in a mist form, thereby extinguishing the fire in key battery components such as the cell modules within the housing. The atomizing nozzle 41 has high spray efficiency and a wide coverage area of the sprayed atomized fire-extinguishing agent, which can improve the fire-extinguishing efficiency of the battery, thereby effectively extinguishing the battery fire in a timely manner and preventing the spread of the fire. The fire-fighting interface 42 and the atomizing nozzle 41 are also simple to install and have high assembly efficiency.

[0078] In this embodiment, in order to improve the assembly efficiency of the battery installation device, a first locking structure 60 is provided between at least one of the first connecting component 21, the short-circuit protection body 31, and the fire protection assembly 40 and the cover plate 10. The first locking structure 60 includes a connecting flange 61, a first connecting hole 62, a first threaded hole 63, and a first locking member 64. The connecting flange 61 is provided around the periphery of at least one of the first connecting component 21, the short-circuit protection body 31, and the fire protection assembly 40. The first connecting hole 62 is provided on the connecting flange 61. The first threaded hole 63 is provided on the cover plate 10 (specifically, located on the first side 11 of the cover plate 10). The first locking member 64 at least partially passes through the first connecting hole 62 and is screwed into the first threaded hole 63, so that at least one of the first connecting member 21 and the short-circuit protection body 31 can be stably and firmly connected to the cover plate 10 through the cooperation of the first locking member 64, the first connecting hole 62 and the first threaded hole 63. At least one of the first connecting member 21 and the short-circuit protection body 31 is connected to the cover plate 10 through the first locking member 64, which not only reduces the installation difficulty, but also reduces the installation process of the battery installation device.

[0079] Specifically, the connecting flange 61 in this embodiment is specifically arranged on the periphery of the terminal socket 212, the first connecting member 311 and the atomizing nozzle 41, and the first locking member 64 uniformly adopts the same type of screws (such as M4 screws), and the screws are at least partially passed through the first connecting hole 62 on the connecting flange 61 to connect with the first threaded hole 63 on the cover plate 10. This is not only simple and convenient to operate, but also can simplify the installation process of the battery mounting device by reducing the types of screws, making the assembly efficiency of the battery mounting device higher.

[0080] Furthermore, a second locking structure 70 is provided between the first connecting component 21 and the second connecting component 22. The second locking structure 70 includes a second threaded hole 71, a second connecting hole 72, and a second locking member 73. The second threaded hole 71 is provided at one end of the positive and negative connecting components 213 and 214, which is closer to the second connecting component 22. The second threaded hole 71 is specifically provided at one end of the terminal sockets 212 of the positive and negative connecting components 213 and 214, which is farther from the wiring terminals 211. The second connecting holes 72 are provided on the first busbar 221 and the third busbar 223. The second locking member 73 at least partially passes through the second connecting hole 72 and is screwed into the second threaded hole 71. Thus, in this embodiment, the first busbar 221 and the second busbar 222 are respectively locked and connected to the corresponding terminal sockets 212 via the second locking members 73 of the second locking structure 70. This not only simplifies operation and reduces installation difficulty, but also achieves a reliable and stable electrical connection between the first connecting member 21 and the second connecting member 22, thereby improving the reliability and stability of the connection between the first connecting member 21 and the second connecting member 22. Moreover, in this embodiment, when the second locking members 73 connecting the first busbar 221 and the third busbar 223 to the corresponding terminal sockets 212 use the same type of locking members (such as M5 screws), the installation process between the first connecting member 21 and the second connecting member 22 can be simplified, thereby improving the assembly efficiency between the first connecting member 32 and the second connecting member 22.

[0081] As can be seen from the above, this embodiment has obtained a battery installation device with multiple functions to improve the safety of battery products. The cover plate 10 of the battery installation device can effectively cover the positive and negative poles of the battery, preventing the operator from touching the positive and negative poles of the battery due to improper operation and causing unnecessary safety hazards, thereby improving the safety of the energy storage battery product and making the battery product more in line with safety standards. The short-circuit protection component 30 installed on the cover plate 10 (specifically a high-voltage connector composed of an MSD socket and an MSD plug) is a specially designed high-voltage connector. When inspecting the battery product, in order to ensure the safety of the operator, the positive and negative pole connection circuits of the battery can be disconnected by pulling out the MSD plug, thereby achieving electrical isolation between the battery and the external power circuit. In addition, the short-circuit protection component 30 also has the function of short-circuit protection. When a short circuit occurs in the high-voltage circuit of the battery, the short-circuit protection component 30 will immediately disconnect the internal fuse and quickly separate the connection of the high-voltage circuit. This design ensures the safety of maintenance work and operators. Since most energy storage devices in the new energy sector use flammable and explosive storage media, a firefighting assembly 40 is also installed on the cover plate 10. This assembly can promptly and effectively extinguish the fire in the event of a battery fire, preventing the spread of the fire and potentially causing safety accidents, thereby improving the safety of the energy storage battery system. Furthermore, a sealing ring 50 provided on the cover plate 10 seals the installation gap between the battery housing and the cover plate 10, thereby improving the protective performance of the battery product. When the sealing ring 50 is a foamed silicone sealant 50, it maintains excellent physical and chemical properties in both high and low temperature environments, and exhibits excellent aging resistance and chemical corrosion resistance, resulting in excellent durability, thereby further extending the service life of the battery product.

[0082] In summary, the battery installation device provided in this embodiment has the following advantages:

[0083] 1) Multifunctionality: The battery installation device is cleverly designed and integrates multiple functions into one, realizing the functions of battery positive and negative pole circuit transmission, short circuit protection and fire safety played by the fire protection component 40 on only one cover plate 10.

[0084] 2) High applicability: The insulating connection assembly 20 (wiring terminal 211 and terminal socket 212), MSD socket, MSD plug and fire protection assembly 40 for connecting to the positive and negative poles of the battery, which are arranged on the cover 10 of the battery installation device, are universal parts, so that the battery installation device can be applied to energy storage battery products in different scenarios, with a high degree of universal matching.

[0085] 3) High Safety: The cover plate 10 effectively covers the positive and negative poles of the battery, preventing people from touching them and causing safety injuries. The short-circuit protection assembly 30, consisting of the MSD socket and MSD plug on the cover plate 10, is a specially designed high-voltage connector. By unplugging the MSD plug, the positive and negative connection circuits of the battery are disconnected, thereby achieving electrical isolation between the battery and the external power circuit. When a short circuit occurs in the battery's high-voltage circuit, the short-circuit protection assembly 30 will immediately disconnect the internal fuse and quickly separate the positive and negative connection circuits of the battery, thereby ensuring the safety of the operator. Because energy storage devices in the new energy field often store flammable and explosive media, a fire protection assembly 40 is also installed on the cover plate 10. Fire protection assembly 40 can promptly and effectively extinguish fires in the event of a battery fire, preventing the fire from spreading and avoiding safety accidents, thereby improving the safety of the energy storage system. Therefore, by installing the short-circuit protection assembly 30 and the fire protection assembly 40, the safety of the power cover plate 10 structure is improved, making the energy storage battery product more compliant with safety standards.

[0086] 4) Good product durability: When the sealing ring 50 provided on the cover plate 10 is a foamed silicone sealing ring 50, the foamed silicone sealing ring 50 can maintain good physical and chemical properties in high and low temperature environments, and has anti-aging properties and chemical corrosion resistance, and has very good durability, which can increase the service life of the battery product. The foamed silicone sealing ring 50 also has certain flame retardancy, insulation properties and other characteristics, and can work stably for a long time.

[0087] A second embodiment of the present invention provides a battery comprising a housing, a cell module, and a battery mounting device. The housing is provided with a receiving slot, within which a cell module is disposed. The cell module includes a positive electrode tab and a negative electrode tab. A cover plate 10 of the battery mounting device is connected to the housing and covers the receiving slot. The positive and negative electrode insulating connectors on the cover plate 10 are electrically connected to the positive and negative electrode tabs, respectively. Once the cover plate 10 is connected to the battery housing, it conceals the cell module and its positive and negative electrodes within the battery housing. This prevents operators from touching the positive and negative electrodes during battery maintenance and inspection, preventing unnecessary safety hazards to the battery and thereby improving the safety of the battery product. Furthermore, the short-circuit protection assembly 30 provided on the cover plate 10 promptly activates short-circuit protection to disconnect the battery from the external power circuit if a short circuit occurs in the cell module. This ensures the safety of battery maintenance personnel and operators, further improving the safety of the battery.
