Description

Technical Field

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

[0002] Energy conservation and emission reduction are the key to the sustainable development of the automobile industry. Electric vehicles have become an important part of the sustainable development of the automobile industry due to their advantages in energy conservation and environmental protection. For electric vehicles, battery technology is an important factor in their development.

[0003] In some cases, the batteries are less safe during transportation or use, posing a greater safety hazard. Summary of the invention

[0004] In view of the above problems, the present application provides a battery and an electrical device, which can improve the safety of the battery and make the battery have lower safety risks.

[0005] In a first aspect, the present application provides a battery, the battery comprising:

[0006] A frame body, the internal structure of which forms a hollow area;

[0007] The bearing body is connected to the frame body;

[0008] The battery unit is arranged in the hollow area and spaced apart from the frame body. The battery unit is arranged on one side of the carrying body along the thickness direction of the frame body, and the battery unit is connected to the carrying body.

[0009] In the present application, when the battery cell is arranged in the hollow area, the carrier body can limit and fix the battery cell along the thickness direction of the frame body to meet the requirements of battery cell assembly. In addition, the battery cell and the frame body are arranged at a distance, which can greatly reduce the possibility of collision and deformation of the battery cell and the frame body during transportation and use, thereby reducing the risk of deformation or even explosion of the battery cell, so that the battery has a higher safety performance.

[0010] In some embodiments, the frame body includes a first longitudinal beam and a second longitudinal beam spaced apart along its width direction, and a first transverse beam and a second transverse beam spaced apart along its length direction. The first longitudinal beam, the first transverse beam, the second longitudinal beam and the second transverse beam are connected end to end in sequence and enclosed to form a hollow area.

[0011] Since battery cells are generally rectangular or cylindrical, by setting the hollow area to a rectangle, the hollow area can be fully utilized and larger battery cells can be arranged in the hollow area, thereby making the battery have a higher space utilization rate.

[0012] In some embodiments, the battery cells are spaced between the first longitudinal beam and the second longitudinal beam, and the battery cells are spaced between the first transverse beam and the second transverse beam.

[0013] With this design, collisions caused by relative movement between the battery unit and the frame body can be prevented, thereby ultimately achieving the goal of improving battery safety.

[0014] In some embodiments, the distance between the battery cell and the first beam is Y1, and the distance between the battery cell and the second beam is Y2, Y1 satisfies the condition: 30 mm ≤ Y1 ≤ 250 mm, and / or Y2 satisfies the condition: 30 mm ≤ Y2 ≤ 250 mm.

[0015] In such a spacing range, the battery unit can be prevented from colliding with the first cross beam and / or the second cross beam, so that the battery has better safety.

[0016] In some embodiments, Y1 satisfies the condition: 50 mm ≤ Y1 ≤ 120 mm, and / or Y2 satisfies the condition: 50 mm ≤ Y2 ≤ 120 mm.

[0017] Within such a spacing range, the battery unit can be prevented from colliding with the first beam and / or the second beam, and the spacing between the battery unit and the first beam and / or the second beam is not too large, thereby making the battery have better space utilization and safety.

[0018] In some embodiments, the spacing between the battery cell 13 and the first longitudinal beam 112 is X1, and the spacing between the battery cell 13 and the second longitudinal beam 113 is X2, X1 satisfies the condition: 30 mm ≤ X1 ≤ 120 mm, and / or X2 satisfies the condition: 30 mm ≤ X2 ≤ 120 mm.

[0019] Within such a spacing range, the battery unit can be prevented from colliding with the first longitudinal beam and / or the second longitudinal beam, so that the battery has better safety.

[0020] In some embodiments, X1 satisfies the condition: 35 mm ≤ X1 ≤ 80 mm, and / or X2 satisfies the condition: 35 mm ≤ X2 ≤ 80 mm.

[0021] Within such a spacing range, the battery unit can be prevented from colliding with the first longitudinal beam and / or the second longitudinal beam, and the spacing between the battery unit and the first longitudinal beam and / or the second longitudinal beam will not be too large, thereby making the battery have better space utilization and safety.

[0022] In some embodiments, it further includes a cover body connected to the frame body, the cover body being arranged on a side of the battery unit facing away from the carrying body;

[0023] The carrying body has a carrying surface facing the battery unit, and the projection of the cover body on the carrying surface at least partially covers the projection of the battery unit on the carrying surface.

[0024] By setting the projection of the cover on the supporting surface to at least partially cover the projection of the battery cell on the supporting surface, the cover can be located below the battery cell and seal at least part of the hollow area, thereby helping to reduce the interference of the external environment where the battery is located on the battery cell.

[0025] In some embodiments, the projection of the cover on the supporting surface completely covers the projection of the battery unit on the supporting surface.

[0026] In this way, the cover can further reduce the interference of the external environment where the battery is located on the battery unit.

[0027] In some embodiments, the cover cooperates with the carrier body and is used to seal the battery cell within the hollow area.

[0028] The battery cells sealed in the hollow area cannot come into contact with water vapor, air and other substances in the external environment, thereby preventing the external environment from interfering with the operation of the battery cells, and making the battery cells have better working reliability and service life.

[0029] In a second aspect, the present application provides an electrical device, comprising a battery as described in any one of the above embodiments, and the battery is used to provide electrical energy to the electrical device.

[0042] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0046] At present, from the perspective of market development, the application of batteries is becoming more and more extensive. 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 electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of battery application areas, its market demand is also constantly expanding.

[0047] The applicant noticed that the battery has low safety during transportation or use, and there are great safety hazards. After careful research, the applicant found that the main reason for the low safety is that during transportation and use, the battery cells in the battery are prone to collide with the frame body in the battery, causing the battery cells to deform or even explode.

[0048] In order to alleviate the problem of low battery safety, the applicant has designed a battery after in-depth research. The battery includes a frame body, a load-bearing body and a battery cell. The internal structure of the frame body forms a hollow area. The load-bearing body is connected to the frame body. The battery cell is arranged in the hollow area and is spaced apart from the frame body. The battery cell is arranged on one side of the load-bearing body along the thickness direction of the frame body, and the battery cell is connected to the load-bearing body. In such a battery, since the battery cell and the frame body are spaced apart, the possibility of collision and deformation of the battery cell and the frame body can be greatly reduced during the transportation and use of the battery, thereby reducing the risk of deformation or even explosion of the battery cell, so that the battery has a higher safety performance.

[0049] The battery disclosed in the embodiment of the present application can be used in, but not limited to, electrical devices such as vehicles, ships or aircraft. A power supply system comprising the battery disclosed in the present application can be used to form the electrical device, which is conducive to alleviating and automatically adjusting the deterioration of the expansion force of the battery cell, replenishing the consumption of the electrolyte, and improving the stability of the battery performance and the battery life.

[0050] The embodiment of the present application provides an electric device using a battery as a power source, and the electric device may be, but is not limited to, a mobile phone, a tablet, a laptop, an electric toy, an electric tool, a battery car, an electric car, a ship, a spacecraft, etc. Among them, the electric toy may include a fixed or mobile electric toy, such as a game console, an electric car toy, an electric ship toy, and an electric airplane toy, etc., and the spacecraft may include an airplane, a rocket, a space shuttle, and a spacecraft, etc.

[0051] For the convenience of description, the following embodiments are described by taking a vehicle as an example of an electrical device in an embodiment of the present application.

[0052] Please refer to Figure 1 , Figure 1 A schematic diagram of the structure of a vehicle 100 provided for some embodiments of the present application. The vehicle 100 may be a fuel vehicle, a gas vehicle or a new energy vehicle, and the new energy vehicle may be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc. A battery 10 is provided at the bottom of the vehicle 100. The battery 10 can be used to power the vehicle 100, for example, the battery 10 can be used as an operating power source for the vehicle 100. The vehicle 100 may also include a controller 20 and a motor 30, and the controller 20 is used to control the battery 10 to power the motor 30, for example, for starting, navigating and driving the vehicle 100.

[0053] In some embodiments of the present application, the battery 10 can be used not only as an operating power source for the vehicle 100 , but also as a driving power source for the vehicle 100 , replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 100 .

[0054] Please refer to Figure 2 and Figure 3 , Figure 2 This is a schematic diagram of the structure of a battery 10 provided in some embodiments of the present application. Figure 3 The top view of the battery 10 provided in some embodiments of the present application without the carrier body 12 is shown. The battery 10 includes a frame body 11, a carrier body 12 and a battery cell 13. The frame body 11 has an internal structure with a hollow area 111. The carrier body 12 is connected to the frame body 11. The battery cell 13 is arranged in the hollow area 111 and is spaced apart from the frame body 11. The battery cell 13 is arranged on one side of the carrier body 12 along the thickness direction of the frame body 11, and the battery cell 13 is connected to the carrier body 12.

[0055] The battery unit 13 includes a plurality of battery cells, and all the battery cells can be connected in series, in parallel, or in a mixed connection to form the battery unit 13. The mixed connection means that the plurality of battery cells are both connected in series and in parallel. All the battery cells can be directly connected in series, in parallel, or in a mixed connection, and then the battery unit 13 composed of the plurality of battery cells is accommodated in the hollow area 111; of course, the plurality of battery cells can also be connected in series, in parallel, or in a mixed connection to form a battery module, and then the plurality of battery modules are connected in series, in parallel, or in a mixed connection to form the battery unit 13, and accommodated in the hollow area 111.

[0056] The battery unit 13 may be disposed on the upper side of the carrier body 12, or the battery unit 13 may also be disposed on the lower side of the carrier body 12. For example, the battery unit 13 is located on the lower side of the carrier body 12, and after the battery 10 is assembled, the carrier body 12 may also be used as the bottom plate of the chassis of the vehicle 100, and the body of the vehicle 100 is carried on the upper side of the carrier body 12 facing away from the battery unit 13.

[0057] The frame body 11 refers to a structure having a certain space inside, and the space can be used to accommodate at least the battery unit 13. The shape of the frame body 11 can be designed in various ways, for example, the shape of the frame body 11 can be designed to be square, round, oval, etc.

[0058] The hollow area 111 refers to a space in the frame body 11 at least for accommodating the battery unit 13. The carrier body 12 may be located in the hollow area 111 or outside the hollow area 111. When the carrier body 12 is located in the hollow area 111, the hollow area 111 is divided by the carrier body 12 to form a first area and a second area. The first area is located on the side of the carrier body 12 facing the battery unit 13 and is used to accommodate the battery unit 13. The second area is located on the side of the carrier body 12 facing away from the battery unit 13 and is used to accommodate other components in the vehicle 100 except the battery unit 13. When the carrier body 12 is located outside the hollow area 111, the hollow area 111 is only used to accommodate the battery unit 13.

[0059] The carrier body 12 may be in a plate, sheet or other shapes. The battery unit 13 and the carrier body 12 may be connected by bonding, screwing or other connection methods.

[0060] In the present application, when the battery cell 13 is disposed in the hollow area 111, the carrier body 12 can limit and fix the battery cell 13 along the thickness direction of the frame body 11 to meet the assembly requirements of the battery cell 13. In addition, the battery cell 13 and the frame body 11 are arranged at intervals, which can greatly reduce the possibility of collision and deformation of the battery cell 13 and the frame body 11 during transportation and use, thereby reducing the risk of deformation or even explosion of the battery cell 13, so that the battery 10 has a higher safety performance.

[0061] Please also read Figure 4 , Figure 5 and Figure 6 , Figure 4 This is a front cross-sectional view of a battery 10 in one embodiment of the present application. Figure 5 This is a side cross-sectional view of a battery 10 in one embodiment of the present application. Figure 6 Schematic diagram of the cooperation between the frame body 11 and the battery 10 in some embodiments of the present application. In some embodiments of the present application, the frame body 11 includes a first longitudinal beam 112 and a second longitudinal beam 113 spaced apart in the width direction X thereof, and a first transverse beam 114 and a second transverse beam 115 spaced apart in the length direction Y thereof, and the first longitudinal beam 112, the first transverse beam 114, the second longitudinal beam 113 and the second transverse beam 115 are sequentially connected end to end and enclosed to form a hollow area 111.

[0062] The first longitudinal beam 112 and the second longitudinal beam 113 both extend along the length direction Y of the frame body 11 , the first transverse beam 114 and the second transverse beam 115 both extend along the width direction X of the frame body 11 , and the first longitudinal beam 112 , the first transverse beam 114 , the second longitudinal beam 113 and the second transverse beam 115 are sequentially connected end to end and enclose a rectangular hollow area 111 .

[0063] Since the battery unit 13 is generally a cuboid or a cylinder, by setting the hollow area 111 to be rectangular, the hollow area 111 can be fully utilized, and larger battery units 13 can be arranged in the hollow area 111, so that the battery 10 has a higher space utilization rate.

[0064] In some embodiments of the application, the battery cells 13 are disposed between the first longitudinal beam 112 and the second longitudinal beam 113 , and the battery cells 13 are disposed between the first transverse beam 114 and the second transverse beam 115 .

[0065] With this design, collisions caused by relative movement between the battery unit 13 and the frame body 11 can be prevented, so that the safety of the battery 10 can be improved.

[0066] In some embodiments of the application, the spacing between the battery cell 13 and the first beam 114 is Y1, and the spacing between the battery cell 13 and the second beam 115 is Y2, Y1 satisfies the condition: 30 mm ≤ Y1 ≤ 250 mm, and / or Y2 satisfies the condition: 30 mm ≤ Y2 ≤ 250 mm.

[0067] For example, only Y1 satisfies the condition: 30 mm ≤ Y1 ≤ 250 mm; or, only Y2 satisfies the condition: 30 mm ≤ Y2 ≤ 250 mm; or, both Y1 and Y2 satisfy the condition: 30 mm ≤ Y1 ≤ 250 mm, 30 mm ≤ Y2 ≤ 250 mm.

[0068] Within such a spacing range, the battery unit 13 can be prevented from colliding with the first cross beam 114 and / or the second cross beam 115 , so that the battery 10 has better safety.

[0069] In some embodiments of the application, Y1 satisfies the condition: 50 mm ≤ Y1 ≤ 120 mm, and / or Y2 satisfies the condition: 50 mm ≤ Y2 ≤ 120 mm.

[0070] For example, only Y1 may satisfy the condition: 50 mm ≤ Y1 ≤ 120 mm; or only Y2 may satisfy the condition: 50 mm ≤ Y2 ≤ 120 mm; or both Y1 and Y2 may satisfy the condition: 50 mm ≤ Y1 ≤ 120 mm, 50 mm ≤ Y2 ≤ 120 mm.

[0071] Within such a spacing range, the battery unit 13 can be prevented from colliding with the first beam 114 and / or the second beam 115, and the spacing between the battery unit 13 and the first beam 114 and / or the second beam 115 is not too large, thereby making the battery 10 have better space utilization and safety.

[0072] In some embodiments of the present application, the spacing between the battery cell 13 and the first longitudinal beam 112 is X1, and the spacing between the battery cell 13 and the second longitudinal beam 113 is X2, X1 satisfies the condition: 30 mm ≤ X1 ≤ 120 mm, and / or X2 satisfies the condition: 30 mm ≤ X2 ≤ 120 mm.

[0073] For example, only X1 may satisfy the condition: 30 mm ≤ X1 ≤ 120 mm; or only X2 may satisfy the condition: 30 mm ≤ X2 ≤ 120 mm; or both X1 and X2 may satisfy the condition: 30 mm ≤ X1 ≤ 120 mm, 30 mm ≤ X2 ≤ 120 mm.

[0074] Within such a spacing range, the battery unit 13 can be prevented from colliding with the first longitudinal beam 112 and / or the second longitudinal beam 113 , so that the battery 10 has better safety.

[0075] In some embodiments of the present application, X1 satisfies the condition: 35 mm ≤ X1 ≤ 80 mm, and / or X2 satisfies the condition: 35 mm ≤ X2 ≤ 80 mm.

[0076] For example, only X1 may satisfy the condition: 35 mm ≤ X1 ≤ 80 mm; or only X2 may satisfy the condition: 35 mm ≤ X2 ≤ 80 mm; or both X1 and X2 may satisfy the conditions: 35 mm ≤ X1 ≤ 80 mm, 35 mm ≤ X2 ≤ 80 mm.

[0077] Within such a spacing range, the battery cell 13 can be prevented from colliding with the first longitudinal beam 112 and / or the second longitudinal beam 113, and the spacing between the battery cell 13 and the first longitudinal beam 112 and / or the second longitudinal beam 113 is not too large, thereby making the battery 10 have better space utilization and safety.

[0078] Please refer again Figure 4 and Figure 5 In some embodiments of the present application, the battery 10 also includes a cover body 14 connected to the frame body 11, and the cover body 14 is arranged on the side of the battery cell 13 facing away from the carrying body 12; the carrying body 12 has a carrying surface 121 facing the battery cell 13, and the projection of the cover body 14 on the carrying surface 121 at least partially covers the projection of the battery cell 13 on the carrying surface 121.

[0079] Specifically, the cover 14 is disposed below the battery unit 13 .

[0080] The cover 14 may be in a plate, sheet or other shapes. The cover 14 and the frame body 11 may be connected by means of buckles, pins, screws, etc.

[0081] By setting the projection of the cover body 14 on the supporting surface 121 to at least partially cover the projection of the battery cell 13 on the supporting surface 121, the cover body 14 can be located below the battery cell 13 and seal at least part of the hollow area 111, thereby helping to reduce the interference of the external environment where the battery 10 is located on the battery cell 13.

[0082] In some embodiments of the present application, the projection of the cover 14 on the carrying surface 121 completely covers the projection of the battery unit 13 on the carrying surface 121 .

[0083] In this way, the cover 14 can further reduce the interference of the external environment where the battery 10 is located on the battery unit 13 .

[0084] In some embodiments of the present application, the cover 14 cooperates with the carrier body 12 and is used to seal the battery unit 13 in the hollow area 111 .

[0085] That is, the frame body 11 , the carrying body 12 and the cover body 14 cooperate with each other and can seal the battery unit 13 in the hollow area 111 .

[0086] The battery cell 13 sealed in the hollow area 111 cannot come into contact with moisture, air and other substances in the external environment, thereby preventing the external environment from interfering with the operation of the battery cell 13 , and making the battery cell 13 have better working reliability and service life.

[0087] According to some embodiments of the present application, the present application further provides an electrical device, comprising the battery 10 described in any of the above schemes, and the battery 10 is used to provide electrical energy to the electrical device.

[0088] The electrical device may be any of the aforementioned devices or systems using the battery 10 .

[0089] According to some embodiments of the present application, see Figures 2 to 5 The present application provides a battery 10, which includes a frame body 11, a cover body 14, a carrier body 12 and a battery cell 13 connected to the carrier body 12. The internal structure of the frame body 11 forms a hollow area 111, and the battery cell 13 is arranged in the hollow area 111. The carrier body 12 and the cover body 14 are both connected to the frame body 11, and the cover body 14 and the carrier body 12 are spaced apart in the thickness direction of the frame body 11 at the lower and upper sides of the battery cell 13, and are used to seal the battery cell 13 in the hollow area 111. The frame body 11 includes a first longitudinal beam 112 and a second longitudinal beam 113 spaced apart along its width direction X, and a first cross beam 114 and a second cross beam 115 spaced apart along its length direction Y. The first longitudinal beam 112, the first cross beam 114, the second longitudinal beam 113 and the second cross beam 115 are sequentially connected end to end and enclosed to form a hollow area 111. The battery cells 13 are spaced apart between the first longitudinal beam 112 and the second longitudinal beam 113, and between the first cross beam 114 and the second cross beam 115.

[0090] When the battery cell 13 is arranged in the hollow area 111, the carrier body 12 can limit and fix the battery cell 13 along the thickness direction of the frame body 11 to meet the requirements of assembling the battery cell 13. In addition, since the battery cell 13 is spaced apart from the first longitudinal beam 112, the second longitudinal beam 113, the first cross beam 114 and the second cross beam 115, during the transportation or use of the battery 10, even if there is relative movement between the frame body 11 and the battery cell 13, there will be no collision between the battery cell 13 and the first longitudinal beam 112, the second longitudinal beam 113, the first cross beam 114 and the second cross beam 115, so as to prevent the frame body 11 or the battery cell 13 from being deformed, thereby improving the safety of the battery 10.

[0091] The cover 14 and the supporting body 12 cooperate to seal the battery cell 13 in the hollow area 111. The battery cell 13 sealed in the hollow area 111 cannot come into contact with water vapor, air and other substances in the external environment, thereby preventing the external environment from interfering with the operation of the battery cell 13, so that the battery cell 13 has better working reliability and service life.

[0092] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0093] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
