[0004] In a first aspect, an embodiment of the present application provides a battery, comprising: a box body and an electrical connection interface, the box body is provided with a first mounting structure, the first mounting structure is suitable for assembling a mounting bracket, the electrical connection interface is provided in the box body, and the first mounting structure is provided adjacent to the electrical connection interface.

[0005] In the technical solution of the embodiment of the present application, a first mounting structure is provided on the box body so that the battery can be assembled with the mounting bracket through the first mounting structure, so that the battery can be fixed to the cabin space of the ship using the mounting bracket. In particular, when the cabin space is an irregular space, the battery installation scheme can be adjusted according to the shape of the cabin space, so as to maximize the use of the cabin space for arranging the battery, thereby improving the utilization rate of the cabin space, and helping to increase the weight energy density and volume energy density of the battery of the ship, thereby improving the cruising range of the ship, and the first mounting structure is arranged adjacent to the electrical connection interface, so as to utilize the space on the wiring side of the battery to install the battery, thereby reducing the occupation of the cabin space by the mounting bracket and helping to reduce the difficulty of assembly.

[0006] In some embodiments, the first mounting structure includes a mounting hole provided in the box body.

[0007] In the above technical solution, the structure of the mounting hole is simpler and easier to produce, which can easily reduce the difficulty of designing and processing the mounting hole to reduce production costs. At the same time, it can reduce the impact on the size of the battery, which is conducive to the miniaturization design of the battery.

[0008] In some embodiments, the first mounting structure includes a plurality of mounting holes, and the plurality of mounting holes are spaced apart along a height direction of the box body.

[0009] In the above technical solution, multiple mounting holes are provided so as to facilitate connection with the mounting bracket through the multiple mounting holes, thereby enhancing the connection strength between the box and the mounting bracket, and the multiple mounting holes are spaced apart along the height direction of the box so as to facilitate assembly connection with the mounting bracket through the mounting holes at different heights, thereby providing more assembly solutions.

[0010] In some embodiments, geometric centers of at least two mounting holes are staggered in height direction.

[0011] In the above technical solution, by setting the geometric centers of at least two mounting holes to be offset in the height direction, the stress concentration problem in the middle area of ​​the two mounting holes is reduced, thereby reducing damage to the mounting holes and ensuring the connection strength between the box and the mounting bracket.

[0012] In some embodiments, the geometric centers of any two adjacent mounting holes are staggered in the height direction.

[0013] In the above technical solution, the geometric centers of any two adjacent mounting holes are set to be offset in the height direction to reduce the stress concentration problem in the middle area of ​​the two adjacent mounting holes, thereby reducing damage to the mounting holes and ensuring the connection strength between the box and the mounting bracket.

[0014] In some embodiments, the plurality of mounting holes include a middle mounting hole, and the mounting holes located on both sides of the middle mounting hole are symmetrically arranged relative to the middle mounting hole.

[0015] In the above technical solution, the mounting holes on both sides of the middle mounting hole are symmetrically arranged relative to the middle mounting hole, so that the distribution of the mounting holes is more uniform, thereby reducing the difficulty of setting the mounting holes.

[0016] In some embodiments, the box body includes a first wall portion, and the first mounting structure is arranged on the first wall portion. In the horizontal direction, the length of the first wall portion is L1, and the horizontal eccentric distance between the geometric centers of the two staggered mounting holes is L2, wherein the ratio of L2 to L1 ranges from 2% to 10%.

[0017] In the above technical solution, the range of the ratio of the horizontal eccentric distance between the geometric centers of the two mounting holes to the length of the first wall portion is limited to ensure that the horizontal eccentric distance is within a reasonable range, thereby ensuring the stability of the structure. At the same time, the space occupied by the two staggered mounting holes in the length direction of the first wall portion can be reduced.

[0018] In some embodiments, the ratio of L2 to L1 ranges from 4% to 5%.

[0019] In the above technical solution, the range of the ratio of the horizontal eccentric distance between the geometric centers of the two mounting holes to the length of the first wall portion is further limited to further ensure that the horizontal eccentric distance is within a reasonable range, thereby ensuring the stability of the structure. At the same time, the space occupied by the two staggered mounting holes in the length direction of the first wall portion can be further reduced.

[0021] In the above technical solution, by limiting the range of the ratio of the height of the first mounting structure to the height of the first wall portion, the first mounting structure is ensured to be larger in the height direction of the first wall portion, thereby ensuring the connection stability between the first mounting structure and the mounting bracket.

[0022] In some embodiments, the ratio of H2 to H1 ranges from 60% to 80%.

[0023] In the above technical solution, by further limiting the range of the ratio of the height of the first mounting structure to the height of the first wall portion, it is ensured that the size of the first mounting structure in the height direction of the first wall portion is larger, thereby ensuring the connection stability between the first mounting structure and the mounting bracket. At the same time, it is possible to more reasonably utilize the space in the height direction of the first wall portion, thereby improving space utilization.

[0024] In some embodiments, the box body further includes embedded nuts arranged corresponding to the mounting holes.

[0025] In the above technical solution, by providing embedded nuts corresponding to the mounting holes, when the box body is connected to the mounting bracket, the bolts can be passed through the mounting bracket and extend into the mounting holes to be connected with the embedded nuts embedded in the mounting holes. In this way, the connection and fixation between the box body and the mounting bracket can be achieved, and there is no need to fix the nuts separately, so as to reduce the difficulty of assembly. In particular, the embedded nuts are embedded in the box body, which can enhance the structural stability of the embedded nuts and enhance the connection strength between the box body and the mounting bracket.

[0026] In some embodiments, the embedded nut is located on the inner side of the outer surface of the box body.

[0027] In the above technical solution, the embedded nut is arranged on the inner side of the outer surface of the second side wall so that the embedded nut will not protrude toward the outer side of the outer surface of the second side wall. In this way, the space occupied on the outer side of the outer surface of the second side wall can be reduced, thereby reducing the impact on the structural dimensions of the box. When the box is stored or transported, the embedded nut will not occupy the space on the outer side of the outer surface of the second side wall, which can avoid interference between the embedded nut and other structures, thereby reducing the difficulty of storage and transportation.

[0028] In some embodiments, the box body includes a first wall portion and a second wall portion, the first wall portion and the second wall portion are adjacent to and connected to each other, the first wall portion is provided with a first mounting structure, and the second wall portion is provided with an electrical connection interface.

[0029] In the above technical solution, the electrical connection interface and the first mounting structure are respectively located on the first wall portion and the second wall portion, that is, the electrical connection port and the first mounting structure are respectively located on different wall portions, so that when the mounting bracket and the first mounting structure are assembled, interference between the mounting bracket and the electrical connection interface can be avoided, thereby reducing damage to the electrical connection interface, facilitating the power connection setting of the electrical connection interface, and helping to reduce assembly difficulty and improve assembly efficiency.

[0030] In some embodiments, the first wall portion is further provided with a second mounting structure, and the second mounting structure is located on a side of the first mounting structure away from the electrical connection interface.

[0031] In the above technical solution, a second mounting structure is provided on a side of the first mounting structure away from the electrical connection interface, so that the second mounting structure and the mounting bracket can be used for assembly, and then the battery can be fixed to the cabin space of the ship using the mounting bracket. In particular, when the cabin space is an irregular space, the mounting bracket can be adjusted according to the shape of the cabin space to assemble with the first mounting structure and / or the second mounting structure, that is, the battery installation scheme is adjusted to maximize the use of the cabin space for arranging the battery, thereby improving the utilization rate of the cabin space, and is beneficial to improving the weight energy density and volume energy density of the battery of the ship, thereby improving the cruising range of the ship.

Since the electrical connection interface is provided on the second wall portion, when the mounting bracket is assembled and connected to the first mounting structure, the space on the wiring side of the electrical connection interface can be used for installation, thereby reducing the difficulty of assembling the mounting bracket.

[0036] In some embodiments, in the horizontal direction, the length of the first wall portion is L1, wherein a ratio of L3 to L1 is less than or equal to 10%.

[0038] In some embodiments, in the horizontal direction, the length of the first wall portion is L1, and the distance between the second mounting structure and the first end is L5, wherein the ratio of L5 to L1 is less than or equal to 80%.

[0085] At present, from the perspective of market development, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in transportation tools such as electric bicycles, electric motorcycles, electric vehicles, ships, as well as military equipment and aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0086] In the related art, ships have various sizes and different uses. There are various types of ships on the market, such as small fishing boats, speedboats, recreational short-distance cruise ships, long-distance passenger ships and cargo ships. When the ship is battery-driven, a specially designed mounting bracket is required for battery assembly. However, the mounting bracket will occupy limited cabin space, which will affect the weight energy density and volume energy density of the ship's battery. In addition, due to the fixed installation method of the battery, when the envelope space is an irregular space, the installation plan cannot be adjusted, and the only option is to reduce the number of installed batteries, thereby reducing the actual space utilization of the ship, thereby reducing the ship's cruising range, increasing the cost of the shipowner, and resulting in poor ship cruising range and ship economy, and low utilization of the ship's envelope space.

[0087] In order to alleviate the problem of the installation bracket occupying the cabin space, a first installation structure suitable for assembling the installation bracket can be provided on the battery. Specifically, it is convenient for the battery to be compatible with different installation brackets for assembly and then fixed in the cabin space. In this way, the installation bracket can reduce the occupation of the cabin space. However, if the first installation structure is set at a position far away from the electrical connection port, it will be difficult to assemble due to insufficient installation space.

[0088] Based on the above considerations, in order to solve the problem of the installation bracket occupying the cabin space and the difficulty in assembling the installation bracket, the present application designs a battery, the battery includes a box body and an electrical connection interface, the box body is provided with a first mounting structure, the first mounting structure is suitable for assembling the installation bracket, the electrical connection interface is provided in the box body, and the first mounting structure is arranged adjacent to the electrical connection interface.

[0089] In such a battery, since the first mounting structure is arranged on the box body, the battery can be assembled through the first mounting structure and the mounting bracket, so that the battery can be fixed to the cabin space of the ship using the mounting bracket. When the cabin space is an irregular space, the battery installation plan can be adjusted according to the shape of the cabin space, so as to maximize the use of the cabin space for arranging the battery, thereby improving the utilization rate of the cabin space, and helping to improve the weight energy density and volume energy density of the ship's battery, thereby improving the ship's cruising range.

[0090] Furthermore, when the battery is installed on a ship, the first mounting structure is arranged adjacent to the electrical connection interface so as to utilize the space on the wiring side of the battery for installation of the battery, thereby reducing the space occupied by the mounting bracket in the cabin and facilitating lowering the difficulty of assembly.

[0091] Against the background of increasing demand for battery energy density, the battery of the present application can make full use of the cabin space for layout, thereby improving the utilization rate of the cabin space, allowing the battery to provide sufficient power support in a limited space, increasing the battery energy density and economic performance, and reducing the cost expenditure of the shipowner.

[0092] The battery disclosed in the embodiments of the present application can be used in an electrical device that uses the battery as a power source or in various energy storage systems that use the battery as an energy storage element.

For example, the battery 100 can be used as an operating power source for the ship. The ship can also include a controller and a motor. The controller is used to control the battery 100 to power the motor, for example, for starting, navigating and driving the ship.

[0095] In some embodiments of the present application, the battery 100 can be used not only as an operating power source for the ship, but also as a driving power source for the ship, replacing or partially replacing fuel oil or natural gas to provide driving power for the ship.

[0096] The battery 100 includes a housing 1 and a battery cell, and the battery cell is contained in the housing 1.

The battery 100 may also include other structures, for example, the battery 100 may also include a converging component for realizing electrical connection between the multiple battery cells.

[0098] Each battery cell may be a secondary battery or a primary battery; it may also be a lithium-sulfur battery, a sodium-ion battery or a magnesium-ion battery, but is not limited thereto. The battery cell may be cylindrical, flat, rectangular or in other shapes, and the battery cell refers to the smallest unit constituting the battery 100. The battery cell includes an end cap, a housing, a cell assembly and other functional components.

[0099] The end cap refers to a component that covers the opening of the shell to isolate the internal environment of the battery cell from the external environment. Without limitation, the shape of the end cap can be adapted to the shape of the shell to match the shell. Optionally, the end cap can be made of a material with a certain hardness and strength (such as aluminum alloy), so that the end cap is not easily deformed when squeezed and collided, so that the battery cell can have a higher structural strength and the safety performance can also be improved.

The material of the end cap can also be a variety of materials, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc., and the embodiments of the present application are not particularly limited to this. In some embodiments, an insulating member can also be provided on the inner side of the end cap, and the insulating member can be used to isolate the electrical connection components in the shell from the end cap to reduce the risk of short circuit. Exemplarily, the insulating member can be plastic, rubber, etc.

[0100] The shell is a component used to cooperate with the end cap to form the internal environment of the battery cell, wherein the formed internal environment can be used to accommodate the battery cell assembly, electrolyte and other components. The shell and the end cap can be independent components, and an opening can be set on the shell, and the internal environment of the battery cell is formed by covering the opening with the end cap at the opening. Without limitation, the end cap and the shell can also be integrated. Specifically, the end cap and the shell can form a common connection surface before other components are put into the shell, and when the interior of the shell needs to be encapsulated, the end cap is covered with the shell. The shell can be of various shapes and sizes, such as a rectangular parallelepiped, a cylindrical shape, a hexagonal prism, etc. Specifically, the shape of the shell can be determined according to the specific shape and size of the battery cell assembly. The material of the shell can be various, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc., and the embodiments of the present application do not impose any special restrictions on this.

[0101] The cell assembly is a component in a battery cell where electrochemical reactions occur. One or more cell assemblies may be contained in the housing. The cell assembly is mainly formed by winding or stacking positive and negative electrode sheets, and a separator is usually provided between the positive and negative electrode sheets. The parts of the positive and negative electrode sheets with active substances constitute the main body of the cell assembly, and the parts of the positive and negative electrode sheets without active substances each constitute a tab. The positive tab and the negative tab may be located together at one end of the main body or respectively at both ends of the main body. During the charge and discharge process of the battery 100, the positive active substance and the negative active substance react with the electrolyte, and the tabs connect the electrode terminals to form a current loop.

[0102] According to some embodiments of the present application, referring to Figures 1 to 4 , Figure 1 A schematic diagram of the structure of a battery 100 according to some embodiments of the present application; Figure 2 for Figure 1 A top view of the battery 100 shown in FIG. Figure 3 for Figure 1 A front view of the battery 100 shown in FIG. Figure 4 for Figure 1 A side view of the battery 100 is shown in FIG.

[0103] An embodiment of the present application provides a battery 100, including: a box body 1 and an electrical connection interface 2, the box body 1 is provided with a first mounting structure 31, the first mounting structure 31 is suitable for assembling a mounting bracket 7, the electrical connection interface 2 is provided in the box body 1, and the first mounting structure 31 is provided adjacent to the electrical connection interface 2.

[0104] The “electrical connection port” includes but is not limited to: a low voltage input socket, a low voltage output socket, a positive electrode interface 23 and a negative electrode interface 24 , and the electrical connection port is used to realize the input or output of the battery cells in the box 1 .

[0105] In “the first mounting structure 31 is suitable for assembling the mounting bracket 7”, the assembly method between the first mounting structure 31 and the mounting bracket 7 includes but is not limited to bolt connection, snap connection, plug connection, magnetic attraction, etc., wherein the first mounting structure 31 can be an assembly structure used in any of the above-mentioned assembly methods and is not limited here.

[0106] Therefore, by providing the first mounting structure 31 on the box body 1, the battery 100 can be assembled with the mounting bracket 7 through the first mounting structure 31, so that the battery 100 can be fixed to the cabin space of the ship using the mounting bracket 7. In particular, when the cabin space is an irregular space, the setting of the mounting bracket 7 is less affected by the shape of the cabin space, so that the installation scheme of the battery 100 can be adjusted according to the shape of the cabin space to maximize the use of the cabin space to arrange the battery 100, thereby improving the utilization rate of the cabin space, and is beneficial to improving the weight energy density and volume energy density of the battery 100 of the ship, thereby improving the cruising range of the ship.

[0107] Furthermore, an electrical connection interface 2 is provided on the box body 1 to facilitate the input or output of the battery 100 through the electrical connection port, wherein a fuse 61 and / or an explosion-proof valve 62 may also be provided on the first side wall, so that the fuse 61 can be used to melt in time when thermal runaway occurs in the battery 100, thereby reducing the risk of thermal runaway of the battery 100, and / or the explosion-proof valve 62 can be used to discharge pressure in time when thermal runaway occurs in the battery 100, thereby reducing the risk of thermal runaway of the battery 100, thereby improving the safety of the battery 100.

[0108] "The first mounting structure 31 is arranged adjacent to the electrical connection interface 2" means that the distance between the first mounting structure 31 and the electrical connection interface 2 is small. For example, the first mounting structure 31 and the electrical connection interface 2 are located on the same side of the battery 100, or the first mounting structure 31 and the electrical connection interface 2 are located on two adjacent side walls and the distance between the first mounting structure 31 and the electrical connection interface 2 is small. No limitation is made here.

[0109] Therefore, it is convenient to utilize the space on the connection side of the battery 100 to install the battery 100, thereby reducing the occupation of the cabin space by the mounting bracket 7 and facilitating lowering the difficulty of assembly.

[0110] According to some embodiments of the present application, optionally, please refer to Figure 1 The first mounting structure 31 includes a mounting hole 3 provided on the box body 1 .

[0111] Therefore, the structure of the mounting hole 3 is simpler and easier to produce, which can easily reduce the difficulty of designing and processing the mounting hole 3 to reduce production costs. At the same time, it can reduce the impact on the size of the battery 100, which is conducive to the miniaturization design of the battery 100.

[0112] For example, the mounting bracket 7 may be provided with a snap-fitting protrusion for connecting and cooperating with the mounting hole 3, so that the mounting bracket 7 can be snap-fitted with the mounting hole 3, or the mounting bracket 7 can be connected to the mounting hole 3 by bolts, specifically, the bolts are passed through the mounting bracket 7 to cooperate with the threads of the mounting hole 3. Of course, the connection method between the mounting bracket 7 and the mounting hole 3 includes but is not limited to the above-mentioned connection method.

[0113] According to some embodiments of the present application, optionally, the mounting hole 3 is formed as a blind hole.

[0114] A "blind via" is a hole that has no conduction at one end.

[0115] Therefore, the mounting hole 3 is set as a blind hole so that the mounting hole 3 will not be connected to the internal space of the box 1, which can ensure the sealing of the internal space of the box 1 and ensure that the protection level of the box 1 is not affected on the basis of achieving the connection between the box 1 and the mounting bracket 7.

[0116] According to some embodiments of the present application, optionally, the first mounting structure 31 includes a plurality of mounting holes 3 , and the plurality of mounting holes 3 are arranged at intervals along a height direction F2 of the box body 1 .

[0117] Therefore, by setting a plurality of mounting holes 3, it is convenient to connect with the mounting bracket 7 through the plurality of mounting holes 3, thereby enhancing the connection strength between the box body 1 and the mounting bracket 7, and the plurality of mounting holes 3 are spaced apart along the height direction F2 of the box body 1, so as to realize assembly connection with the mounting bracket 7 through the mounting holes 3 at different heights, thereby providing more assembly schemes.

[0118] According to some embodiments of the present application, optionally, the geometric centers of at least two mounting holes 3 are staggered in the height direction F2.

[0119] “At least two mounting holes 3” include two mounting holes 3, or three mounting holes 3, or four mounting holes 3 spaced apart in the height direction F2, wherein the two staggered mounting holes 3 may be adjacent or not, which is not limited here.

[0120] “Offset arrangement” means that the projections of the two mounting holes 3 in the height direction F2 do not overlap, that is, the line connecting the geometric centers of the two adjacent mounting holes 3 intersects with the height direction F2.

[0121] Therefore, by setting the geometric centers of at least two mounting holes 3 to be offset in the height direction F2, the problem of stress concentration in the middle area of ​​the two mounting holes 3 can be reduced, thereby reducing damage to the mounting holes 3 and ensuring the connection strength between the box body 1 and the mounting bracket 7.

[0122] According to some embodiments of the present application, optionally, the geometric centers of any two adjacent mounting holes 3 are staggered in the height direction F2.

[0123] Therefore, by setting the geometric centers of any two adjacent mounting holes 3 to be offset in the height direction F2, the problem of stress concentration in the middle area of ​​the two adjacent mounting holes 3 can be reduced, thereby reducing damage to the mounting holes 3 and ensuring the connection strength between the box 1 and the mounting bracket 7.

[0124] According to some embodiments of the present application, optionally, the plurality of mounting holes 3 include a middle mounting hole 3a, and the mounting holes 3 located on both sides of the middle mounting hole 3a are symmetrically arranged relative to the middle mounting hole 3a.

[0125] Therefore, by arranging the mounting holes 3 located on both sides of the middle mounting hole 3 a symmetrically relative to the middle mounting hole 3 a, the distribution of the mounting holes 3 is made more uniform, which facilitates reducing the difficulty of arranging the mounting holes 3 .

[0126] According to some embodiments of the present application, optionally, please refer to Figure 4 The box body 1 includes a first wall portion 11, and the first mounting structure 31 is arranged on the first wall portion 11. In the horizontal direction F1, the length of the first wall portion 11 is L1, and the horizontal eccentric distance between the geometric centers of the two staggered mounting holes 3 is L2, wherein the ratio of L2 to L1 ranges from 2% to 10%.

[0127] It should be noted that the relationship between the horizontal eccentric distance between the geometric centers of the two staggered mounting holes 3 and the stability tends to a negative quadratic distribution, that is, as the horizontal eccentric distance increases, the stability increases. When a certain node is reached, the increase in the eccentric distance will lead to a decrease in stability. Therefore, the size of the horizontal eccentric distance needs to be limited.

[0128] In the present application, the length L1 of the first wall portion 11 is used as a reference, and the size of the horizontal eccentric distance is limited by the ratio of the horizontal eccentric distance L2 to L1. For example, the ratio of L2 and L1 is 2%, 3%, or 4%. That is, when the ratio of L2 and L1 is within the value range, it can ensure that the horizontal eccentric distance is within a reasonable range, thereby ensuring the stability of the structure. At the same time, it can reduce the space occupied by the two staggered mounting holes 3 in the length direction of the first wall portion 11.

[0129] According to some embodiments of the present application, optionally, the ratio of L2 to L1 ranges from 4% to 5%.

[0130] For example, the ratio of L2 and L1 is 4%, or 4.5%, or 5%. That is, when the ratio of L2 and L1 satisfies the above range of values, the range of values ​​of the ratio of the horizontal eccentric distance between the geometric centers of the two mounting holes 3 to the length of the first wall portion 11 can be further narrowed to further ensure that the horizontal eccentric distance is within a reasonable range, thereby ensuring the stability of the structure. At the same time, the space occupied by the two staggered mounting holes 3 in the length direction of the first wall portion 11 can be further reduced.

[0131] According to some embodiments of the present application, optionally, please refer to Figure 4 The box body 1 includes a first wall portion 11, and the first mounting structure 31 is disposed on the first wall portion 11. The height of the first wall portion 11 is H1, and the height of the first mounting structure 31 is H2, wherein the ratio of H2 to H1 is greater than or equal to 50%.

[0132] It should be noted that, since the first mounting structure 31 is assembled with the mounting bracket 7 , the height of the first mounting structure 31 will affect the assembly stability of the first mounting structure 31 and the mounting bracket 7 .

[0133] In the present application, the height H1 of the first wall portion 11 is used as a reference, and the height H2 of the first mounting structure 31 is limited by the ratio of the height H2 of the first mounting structure 31 to H1. For example, the ratio of H2 to H1 is 51%, 55%, or 80%. That is, when the ratio of H2 to H1 is within the above-mentioned range of values, it can ensure that the size of the first mounting structure 31 in the height direction F2 of the first wall portion 11 is larger, thereby ensuring the assembly stability of the first mounting structure 31 and the mounting bracket 7.

[0134] According to some embodiments of the present application, optionally, the ratio of H2 to H1 ranges from 60% to 80%.

[0135] Therefore, by further limiting the range of the ratio of the height H2 of the first mounting structure 31 to the height H1 of the first wall portion 11, it is ensured that the first mounting structure 31 has a larger size in the height direction F2 of the first wall portion 11, thereby ensuring the connection stability between the first mounting structure 31 and the mounting bracket 7. At the same time, it is possible to more reasonably utilize the space in the height direction F2 of the first wall portion 11, thereby improving space utilization.

[0136] According to some embodiments of the present application, optionally, the box body 1 further includes an embedded nut 4 arranged corresponding to the mounting hole 3 .

[0137] Therefore, by providing the embedded nut 4 corresponding to the mounting hole 3, when the box body 1 is connected to the mounting bracket 7, the bolt can be passed through the mounting bracket 7 and extend into the mounting hole 3 to be connected with the embedded nut 4 embedded in the mounting hole 3. In this way, the connection and fixation between the box body 1 and the mounting bracket 7 can be achieved, and there is no need to fix the nut separately to reduce the difficulty of assembly. In particular, the embedded nut 4 is embedded in the box body 1, which can enhance the structural stability of the embedded nut 4 and enhance the connection strength between the box body 1 and the mounting bracket 7.

[0138] According to some embodiments of the present application, optionally, the embedded nut 4 is located on the inner side of the outer surface of the box body 1 .

[0139] "Inside" refers to the side of the outer surface of the box body 1 facing the battery cell inside the box body 1, that is, the side of the outer surface of the box body 1 away from the external space of the box body 1, that is, the embedded nut 4 does not protrude outside the outer surface of the box body 1, so as to avoid insufficient connection strength between the embedded nut 4 and the box body 1 or interference between the embedded nut 4 and other structures during transportation of the box body 1.

[0140] Therefore, by arranging the embedded nut 4 on the inner side of the outer surface of the second side wall, the embedded nut 4 will not protrude toward the outer side of the outer surface of the second side wall. In this way, the space occupied on the outer side of the outer surface of the second side wall can be reduced, thereby reducing the impact on the structural dimensions of the box body 1. When the box body 1 is stored or transported, the embedded nut 4 will not occupy the space on the outer side of the outer surface of the second side wall, which can avoid interference between the embedded nut 4 and other structures, thereby reducing the difficulty of storage and transportation.

[0141] According to some embodiments of the present application, optionally, the box body 1 includes a first wall portion 11 and a second wall portion 12 , the first wall portion 11 and the second wall portion 12 are adjacent and connected, the first wall portion 11 is provided with a first mounting structure 31 , and the second wall portion 12 is provided with an electrical connection interface 2 .

[0142] “The first wall portion 11 and the second wall portion 12 ” refer to two adjacent and connected side walls of the box body 1 .

[0143] Therefore, the electrical connection interface 2 and the first mounting structure 31 are respectively located on the first wall portion 11 and the second wall portion 12, that is, the electrical connection port and the first mounting structure 31 are respectively located on different wall portions, so that when the mounting bracket 7 and the first mounting structure 31 are assembled, interference between the mounting bracket 7 and the electrical connection interface 2 can be avoided, thereby reducing damage to the electrical connection interface 2, facilitating the power connection setting of the electrical connection interface 2, and helping to reduce the difficulty of assembly and improve assembly efficiency.

[0144] According to some embodiments of the present application, optionally, the first wall portion 11 is further provided with a second mounting structure 32 , and the second mounting structure 32 is located on a side of the first mounting structure 31 away from the electrical connection interface 2 .

[0145] Therefore, by setting the second mounting structure 32 on the side of the first mounting structure 31 away from the electrical connection interface 2, the second mounting structure 32 and the mounting bracket 7 can be assembled, and then the mounting bracket 7 can be used to fix the battery 100 to the cabin space of the ship.

[0146] For example, when it is necessary to fix the battery 100 on the side of the first mounting structure 31 away from the electrical connection interface 2, the second mounting structure 32 can be used to assemble with the mounting bracket 7, thereby fixing the battery 100 to the cabin space of the ship. Alternatively, when the cabin space is an irregular space, the mounting bracket 7 can be adjusted to assemble with the first mounting structure 31 and / or the second mounting structure 32 according to the shape of the cabin space, that is, the installation scheme of the battery 100 is adjusted, so as to maximize the use of the cabin space to arrange the battery 100, thereby improving the utilization rate of the cabin space, and is conducive to improving the weight energy density and volume energy density of the battery 100 of the ship, thereby improving the cruising range of the ship.

[0147] At the same time, the arrangement of the second mounting structure 32 can adapt to the design that the center of gravity of the battery 100 is located at a side away from the electrical connection interface 2 , thereby ensuring the structural stability of the battery 100 .

[0148] According to some embodiments of the present application, optionally, the shape of the second mounting structure 32 is the same as the shape of the first mounting structure 31 .

[0149] For example Figure 4 As shown, the second mounting structure 32 may also include a plurality of mounting holes 3, and the arrangement mode and number of the mounting holes 3 are the same as those of the mounting holes 3 of the first mounting structure 31, and can also achieve the same function, which is not limited here.

[0150] Therefore, by setting the shape of the second mounting structure 32 to be the same as the shape of the first mounting structure 31 , the difficulty of setting the second mounting structure 32 can be simplified.

[0151] According to some embodiments of the present application, optionally, in the horizontal direction F1, the first end 111 of the first wall portion 11 is connected to the second wall portion 12, the minimum distance between the first mounting structure 31 and the first end 111 of the first wall portion 11 is L3, and the minimum distance between the second mounting structure 32 and the second end 112 of the first wall portion 11 is L4, where L3<L4.

[0152] It should be noted that, under the installation condition that the cabin space for arranging the battery 100 on a ship is narrow, the first mounting structure 31 is arranged at a position closer to the first end 111, that is, closer to the electrical connection interface 2, so that the first mounting structure 31 can utilize the power connection space on the side of the electrical connection interface 2 when assembled with the mounting bracket 7, thereby reducing the difficulty of assembly.

[0153] Therefore, by limiting the size relationship between the minimum distance between the first mounting structure 31 and the first end 111 of the first wall portion 11 and the minimum distance between the second mounting structure 32 and the second end 112 of the first wall portion 11, the setting of the second mounting structure 32 can adapt to the design that the center of gravity of the battery 100 is located on the side away from the electrical connection interface 2, and the first mounting structure 31 is made closer to the second wall portion 12. Since the electrical connection interface 2 is provided on the second wall portion 12, when the mounting bracket 7 is assembled and connected to the first mounting structure 31, the space on the wiring side of the electrical connection interface 2 can be used for installation, thereby reducing the difficulty of assembling the mounting bracket 7.

[0154] According to some embodiments of the present application, optionally, in the horizontal direction F1, the length of the first wall portion 11 is L1, wherein a ratio of L3 to L1 is less than or equal to 10%.

[0155] It should be noted that the setting of "the first mounting structure 31 is adjacent to the electrical connection interface 2" in the present application can be reflected by the ratio of L3 and L1. For example, the ratio of L3 and L1 is 2%, or 5%, or 8%. That is, when the ratio of L3 and L1 is within the above-mentioned range of values, the range of values ​​of the ratio of the minimum distance between the first mounting structure 31 and the first end 111 of the first wall portion 11 to the length of the first wall portion 11 can be limited, so that the first mounting structure 31 is closer to the electrical connection interface 2, that is, the setting of the first mounting structure 31 adjacent to the electrical connection interface 2 is realized, so that when the mounting bracket 7 is assembled and connected to the first mounting structure 31, the space on the wiring side of the electrical connection interface 2 can be used for installation, thereby reducing the difficulty of assembling the mounting bracket 7.

[0156] According to some embodiments of the present application, optionally, in the horizontal direction F1, the length of the first wall portion 11 is L1, and the distance between the second mounting structure 32 and the first end 111 is L5, wherein the ratio of L5 to L1 is less than or equal to 80%.

[0157] For example, the ratio of L5 and L1 is 50%, 60%, or 70%. That is, when the ratio of L5 and L1 satisfies the above range of values, the range of values ​​of the ratio of the distance between the second mounting structure 32 and the first end 111 of the first wall portion 11 to the length of the first wall portion 11 can be limited so that the second mounting structure 32 will not be too far from the electrical connection interface 2, thereby making the position of the second mounting structure 32 adapt to the design in which the center of gravity of the battery 100 is located on the side away from the electrical connection interface 2.

[0158] According to some embodiments of the present application, optionally, a handle 5 is provided on the first side wall.

[0159] The "handle 5" includes but is not limited to a pull ring, a pull rod, a protrusion, etc., and is not limited here.

[0160] Therefore, by arranging the handle 5 on the first side wall, it is convenient to hold the handle 5 to realize the transportation and carrying of the box 1, thereby reducing the difficulty of carrying the box 1, and the handle 5 is located on the first side wall, and the mounting position is located on the second side wall, which can avoid the interference between the handle 5 and the mounting bracket 7.

[0161] According to some embodiments of the present application, optionally, please refer to Figure 6-Figure 15 The battery 100 further includes a plurality of mounting brackets 7 , the plurality of mounting brackets 7 have different shapes, and each mounting bracket 7 cooperates with the first mounting structure 31 .

[0162] Therefore, each mounting bracket 7 can be matched with the first mounting structure 31, so that the battery 100 can be compatible with different mounting brackets 7 for assembly, thereby enabling the battery 100 to have more assembly schemes. In this way, when the cabin space is an irregular space, different mounting brackets 7 can be used in combination with the first mounting structure 31 according to the shape of the cabin space, that is, the installation scheme of the battery 100 is adjusted, so as to maximize the use of the cabin space to arrange the battery 100, thereby improving the utilization rate of the cabin space, and is beneficial to improving the weight energy density and volume energy density of the battery 100 of the ship, thereby improving the cruising range of the ship.

[0163] According to some embodiments of the present application, optionally, please refer to Figure 6 and Figure 7 , Figure 6 is a schematic diagram of the first mounting bracket 71 of the present application; Figure 7 yes Figure 6 The assembly diagram of the first mounting bracket 71 and the battery 100 shown in the figure; the multiple mounting brackets 7 include a first mounting bracket 71, the first mounting bracket 71 includes a first mounting member 711 and a second mounting member 712, the first mounting member 711 cooperates with the first mounting structure 31 and the second mounting member 712 is located on the side of the first mounting member 711 facing the electrical connection interface 2, and the second mounting member 712 is provided with a first fixing hole 76.

[0164] Therefore, the first mounting member 711 cooperates with the first mounting structure 31, and the second mounting member 712 is provided with a first fixing hole 76, so that the first mounting bracket 71 can be fixed to the cabin space using the first fixing hole 76, and the second mounting member 712 is located on the side of the first mounting member 711 facing the electrical connection interface 2, so as to realize the fixation of the front side of the battery 100 when there is not enough installation space on the rear side of the battery 100 and it cannot be fixed.

[0165] It is worth mentioning that the first mounting bracket 71 is suitable for assembly schemes with limited space in the width direction of the cabin space. For example, the first mounting member 711 has a plurality of connection holes 78, and the first mounting structure 31 includes a plurality of mounting holes 3. During actual installation, when the rear end of the battery 100 is close to the cabin, there is no operating space for tightening the rear mounting bolts. At this time, only the first mounting bracket 71 needs to be installed. The plurality of connection holes 78 and the plurality of mounting holes 3 correspond one to one. During actual assembly, the connection holes 78 are directly opposite to the mounting holes 3. The bolts are sequentially passed through the connection holes 78 and the mounting holes 3 to be connected with the embedded nuts 4. Then, the first fixing holes 76 of the first mounting bracket 71 can be fixed to the fixing point of the battery 100 rack or the cabin. In this way, the front side of the battery 100 can be fixed.

[0166] According to some embodiments of the present application, optionally, please refer to Figure 8 and Fig.10 , Figure 8 is a schematic diagram of the second mounting bracket 72 of the present application; Fig. 9 yes Figure 8 An assembly diagram of the second mounting bracket 72 and the battery 100 shown in FIG. Fig.10 yes Fig. 9 FIG. 4 is a schematic diagram of a plurality of batteries 100 stacked in a height direction F2 .

[0167] The multiple mounting brackets 7 include a second mounting bracket 72, the second mounting bracket 72 includes a third mounting member 721 and a fourth mounting member 722, both ends of the third mounting member 721 in the height direction F2 are provided with fourth mounting members 722, the third mounting member 721 cooperates with the first mounting structure 31, and the fourth mounting member 722 is provided with a second fixing hole 77.

[0168] Therefore, the third mounting member 721 cooperates with the first mounting structure 31, and the fourth mounting member 722 is provided with a second fixing hole 77, so that the second mounting bracket 72 can be fixed to the cabin space by using the second fixing hole 77, and the fourth mounting member 722 is located at both ends of the third mounting member 721 in the height direction F2, so that in the height direction F2 of the battery 100, two adjacent fourth mounting members 722 can be connected by bolts, thereby realizing the stacking of multiple batteries 100 in the height direction F2.

[0169] It is worth noting that the second mounting bracket 72 is suitable for the assembly mode of more than two layers of batteries 100. For example, the third mounting member 721 has a plurality of connecting holes 78, and the first mounting structure 31 includes a plurality of mounting holes 3. The plurality of connecting holes 78 and the plurality of mounting holes 3 included in the mounting position correspond to each other. In actual assembly, the connecting holes 78 are directly opposite to the mounting holes 3. The bolts are sequentially passed through the connecting holes 78 and the mounting holes 3 to be connected with the embedded nuts 4 to realize the connection between the battery 100 and the second mounting bracket 72. Fig.10An external frame 9 is provided on the outside of the battery 100, and the second mounting brackets 72 of two adjacent batteries 100 in the height direction F2 are respectively connected to the external frame 9 through the second fixing holes 77, so that the two batteries 100 are stacked in the height direction F2 to be assembled into a whole, and then the whole is installed in the cabin space. In this way, multiple batteries 100 can be stacked in the height direction F2 on the outside of the cabin space and then assembled into the cabin space as a whole, thereby reducing the difficulty of assembling the batteries 100.

[0170] According to some embodiments of the present application, optionally, please refer to Figure 11-13 , Fig.11 is a schematic diagram of a third mounting bracket 73 of the present application; Fig.12 yes Fig.11 The assembly diagram of the third mounting bracket 73 and the battery 100 shown in FIG. Fig.13 yes Fig.12 FIG. 1 is a schematic diagram of a plurality of batteries 100 laid out horizontally.

[0171] The multiple mounting brackets 7 include a third mounting bracket 73, which includes a fifth mounting member 731 and a sixth mounting member 732, wherein the sixth mounting member 732 is connected to the lower end of the fifth mounting member 731, the fifth mounting member 731 cooperates with the first mounting structure 31, and the sixth mounting member 732 is provided with a third fixing hole 79.

[0172] Thus, the fifth mounting member 731 cooperates with the first mounting structure 31, and the sixth mounting member 732 is connected to the lower end of the fifth mounting member 731, so that the third mounting bracket 73 can be fixed to the cabin space by using the third fixing hole 79 of the sixth mounting member 732, and the sixth mounting member 732 is located at the lower end of the fifth mounting member 731, so that when the battery 100 is laid flat in the horizontal direction F1, the sixth mounting member 732 can be used to achieve the flat fixing of the battery 100.

[0173] It is worth noting that the third mounting bracket 73 is suitable for the installation scheme in which the horizontal direction F1 space of the cabin is large and the vertical direction space is small. At this time, the battery 100 can be directly installed on the cabin through the flat bracket 8. For example, the fifth mounting member 731 has a plurality of connection holes 78, and the first mounting structure 31 includes a plurality of mounting holes 3. The plurality of connection holes 78 and the plurality of mounting holes 3 included in the mounting position correspond one to one.

In this way, the fourth mounting bracket 74 and the first mounting structure 31 can be used to cooperate to realize the lifting and transportation of the battery 100.

Then the lifting mechanism can be mounted on the first hook portion to drive the battery 100 to move, thereby reducing the difficulty of transporting the battery 100. After being transported to the designated location, the seventh mounting member can be separated from the first mounting structure 31, and then the first mounting structure 31 can be assembled with other mounting brackets 7.

[0180] Therefore, by setting the lifting bracket 75, when transporting the battery 100, the lifting bracket 75 can be assembled with the first mounting structure 31 first, and then the lifting mechanism can be mounted on the second hook portion of the lifting bracket 75 to drive the battery 100 to move, thereby reducing the difficulty of transporting the battery 100, and after transportation to the destination, the lifting bracket 75 can be separated from the first mounting structure 31, so that the first mounting structure 31 can be assembled with both the mounting bracket 7 and the lifting bracket 75, thereby broadening the scope of use of the first mounting structure 31 and improving the versatility of the first mounting structure 31.

[0181] For example, the hanging bracket 75 is provided with a plurality of connecting holes 78, and the first mounting structure 31 includes a plurality of mounting holes 3. The plurality of connecting holes 78 and the plurality of mounting holes 3 correspond one to one. During actual assembly, the connecting holes 78 are opposite to the mounting holes 3.

The second hook portion is located on the side of the hanging bracket 75 away from the battery 100. Then the hanging mechanism can be mounted on the second hook portion to drive the battery 100 to move, thereby reducing the difficulty of transporting the battery 100. After being transported to the designated location, the hanging bracket 75 can be separated from the first mounting structure 31, and then the first mounting structure 31 can be assembled with other mounting brackets 7. In this way, the first mounting structure 31 can be used for both fixing the battery 100 and transporting the battery 100, thereby expanding the scope of use of the first mounting structure 31 and improving the versatility of the first mounting structure 31.
