Description

Technical Field

[0001] The present application relates to the field of batteries, 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 order to achieve the assembly positioning of the battery, a protrusion is often provided on one of the box and the battery cell, and a depression matching the protrusion is provided on the other. During assembly, the battery is accurately positioned by matching the depression with the protrusion. However, the above positioning method requires the provision of a protrusion or a depression on each battery cell, which increases the preparation cost and has a low assembly efficiency. Therefore, how to improve the assembly efficiency of the battery has become an issue that needs to be solved urgently. Utility Model Content

[0004] In view of the above problems, the present application provides a battery and an electrical device, which can achieve precise assembly of battery cells and improve battery assembly efficiency.

[0005] In a first aspect, the present application provides a battery, comprising a box body having a accommodating cavity; a positioning assembly arranged in the accommodating cavity, the positioning assembly comprising a plurality of positioning members, the plurality of positioning members being arranged at intervals from each other and respectively connected to the box body, and a partition cavity being formed between two adjacent positioning members; a battery pack, each battery pack comprising at least one battery cell, a battery pack being arranged in at least part of the partition cavity, and the battery pack being clamped between two adjacent positioning members.

[0006] In the embodiment of the present application, by connecting a positioning piece to the box body, the accommodating cavity in the box body can be divided into multiple partition cavities by the positioning piece. The battery pack can be positioned and assembled in each partition cavity to limit the position of the battery pack, thereby achieving precise assembly of battery cells in the battery pack and improving battery assembly efficiency.

[0007] In some embodiments, the positioning member and the box body are configured as an integrated structure. For example, the positioning member can be integrally manufactured with the box body, or the positioning member can be formed by stamping the box body toward one side of the accommodating cavity, and the specific preparation process can be adjusted according to the specific structure of the box body.

[0008] In some embodiments, the box body includes a bottom wall and a side wall arranged around the bottom wall, the bottom wall and the side wall are combined to form a receiving cavity, and at least one of the bottom wall and the side wall is provided with a positioning member to limit the surrounding side of the battery pack, further improving the limiting effect of the battery pack and improving the reliability of the battery pack assembled in the box body. In some embodiments, a plurality of positioning members are arranged at intervals along a first direction, the positioning member is arranged on the bottom wall and protrudes a preset distance relative to the bottom wall along a second direction, two adjacent positioning members and the bottom wall are combined to form a spacing cavity, and the second direction intersects with the first direction. That is, the positioning member can have a preset height, so that after the battery pack is arranged in the spacing cavity, it can be limited by the positioning member, further improving the reliability of the assembled battery cell. In addition, the overflow state of the battery cell can also be improved.

[0009] In some embodiments, each positioning member has a preset thickness along the first direction, and the battery also includes a heat exchange structure, which is arranged corresponding to the positioning member along the second direction, and the thickness of the heat exchange structure along the first direction is less than or equal to the thickness of the positioning member along the first direction.

[0010] In the embodiment of the present application, a heat exchange structure can be arranged corresponding to the positioning member. After the battery pack is arranged in the partition cavity, the heat exchange structure is clamped between two adjacent battery packs along the first direction, thereby realizing the cooling of the battery cells and being able to more reasonably utilize the space inside the battery, thereby improving the battery energy density.

[0011] In some embodiments, one of the heat exchange structure and the positioning member is provided with a convex portion, and the other is provided with a concave portion, and the convex portion matches the concave portion to clamp the heat exchange structure in the accommodating cavity along the first direction, thereby simultaneously achieving the limitation of the battery pack and the heat exchange structure, further improving the reliability of the battery after assembly.

[0012] In some embodiments, the positioning members are continuously arranged along the third direction, and the third direction intersects with the first direction and the second direction; or, the positioning member includes more than two positioning units, and the more than two positioning units are arranged at intervals along the third direction. That is, the positioning member can extend from one end of the bottom wall to the other end along the third direction to separate and form a partition cavity, and the positioning member can also be arranged at intervals along the third direction to reduce the overall weight of the battery while separating and forming the partition cavity.

[0013] In some embodiments, the battery pack includes more than two battery cells along the third direction. Since the positioning member is extended along the third direction, when laying out the battery pack, the battery cells in the battery pack can be arranged along the third direction, thereby facilitating the assembly and arrangement of the battery.

[0014] In some embodiments, along the first direction, each battery pack includes one or two battery cells, and the battery packs and the compartments are arranged in a one-to-one correspondence.

[0015] In the embodiment of the present application, the number of battery packs is the same as the number of compartments and they are arranged in each compartment in a one-to-one correspondence. By arranging the battery packs and the compartments in a one-to-one correspondence, the internal space of the battery can be reasonably utilized to improve the energy density of the battery. For each battery pack, the battery pack may include one or two battery cells, and each battery cell can be assembled and positioned to improve the reliability of the battery cell assembly in the box, and when the positioning member is correspondingly provided with a heat exchange structure, each battery cell can also be in contact with the heat exchange structure, thereby improving the reliability of the battery as a whole.

[0016] In some embodiments, the positioning member is provided with a guide surface, which is inclined relative to the box body, and the battery pack is introduced into the compartment cavity through the guide surface, thereby further improving the assembly efficiency and reducing the difficulty of assembly.

[0017] In a second aspect, an embodiment of the present application provides an electrical device, comprising the battery of the first aspect, and the battery is used to provide electrical energy.

[0018] According to the battery of the embodiment of the present application, the battery includes a box, a positioning assembly and a battery pack, the battery pack includes at least one battery cell, the positioning assembly includes a plurality of positioning members, the plurality of positioning members are connected to the box, and the accommodating cavity in the box is divided into a plurality of compartments, so that the placement area of ​​the battery pack is limited by the positioning members. The above positioning method only requires connecting the positioning members to the battery box, without changing the structure of the battery cell, reducing the manufacturing cost, and the battery pack can be respectively arranged in each compartment, while realizing the precise assembly of the battery cell, improving the assembly efficiency of the battery.

[0033] The following embodiments of the technical solution of the present application are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present application, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present application.

[0034] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in the embodiments of the present application should have the common meanings understood by technicians in the field to which the embodiments of the present application belong.

[0035] In the description of the embodiments of the present application, the orientations or positional relationships indicated by technical terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", and "circumferential" are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the embodiments of the present application.

[0036] In addition, the technical terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. In the description of the embodiments of the present application, the meaning of "multiple" is more than two, unless otherwise clearly and specifically defined.

[0037] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0038] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0039] In existing batteries, in order to achieve assembly positioning of the battery, a limiting protrusion is often set on the battery end plate, and a limiting recess is set on each battery cell. By coordinating the limiting protrusion of the end plate with the limiting recess of the battery cell, the first battery cell and the battery end plate are positioned to facilitate the subsequent assembly of other battery cells, thereby ensuring the assembly accuracy of the battery.

[0040] However, the applicant noted that the above-mentioned assembly alignment method requires that a limiting protrusion or a limiting depression be set on each battery cell, which will increase the space occupied by the battery cell and affect the energy density of the battery. In addition, the preparation steps of a single battery cell are increased, which increases the preparation cost. Based on the above considerations, the embodiment of the present application provides a new battery structure. By setting a positioning piece on the battery case, the precise assembly of the battery cell can be achieved without changing the structure of the battery cell. The battery and the electrical device of the embodiment of the present application are further described below in conjunction with the accompanying drawings.

[0041] See also Figure 1 and Figure 2The battery 10 provided in the embodiment of the present application includes a box body 1, a positioning assembly and a battery cell 3. The box body 1 has a accommodating cavity, the positioning assembly is arranged in the accommodating cavity, the positioning assembly includes a plurality of positioning members 2, the plurality of positioning members 2 are arranged at intervals from each other and are respectively connected to the box body 1, a spacing cavity is formed between two adjacent positioning members 2, each battery pack includes at least one battery cell 3, a battery pack is arranged in at least part of the spacing cavity, and the battery pack is clamped between two adjacent positioning members 2.

[0042] In the battery 10 in the embodiment of the present application, a plurality of positioning members 2 are connected to the box body 1, and the accommodating cavity in the box body 1 is divided into a plurality of compartments, so that the placement area of ​​the battery pack is limited by the positioning members 2. The above positioning method only requires connecting the positioning members 2 to the box body 1, and does not need to change the structure of the battery cell 3, thereby reducing the manufacturing cost, and the battery pack can be respectively arranged in each compartment, thereby improving the assembly efficiency of the battery 10 while realizing the precise assembly of the battery cell 3.

[0043] In the embodiment of the present application, the battery cell 3 may be a secondary battery cell. A secondary battery cell refers to a battery cell 3 that can be continuously used by activating active materials by charging after the battery cell 3 is discharged.

[0044] In the embodiment of the present application, the battery cells 3 include but are not limited to lithium-ion battery cells, sodium-ion battery cells, sodium-lithium-ion battery cells, lithium metal battery cells, sodium metal battery cells, lithium-sulfur battery cells, magnesium-ion battery cells, nickel-hydrogen battery cells, nickel-cadmium battery cells, lead-acid battery cells, etc.

[0045] As an example, the battery cell 3 may be a cylindrical battery cell, a prismatic battery cell, a soft-pack battery cell or a battery cell of other shapes. The prismatic battery cell includes a square-shell battery cell, a blade-shaped battery cell, a polygonal battery, such as a hexagonal battery.

[0046] It is understandable that one battery cell 3 or more than two battery cells 3 may be arranged in the compartment. Furthermore, the battery cell 3 may be arranged in the box body 1 in the horizontal direction or in the vertical direction, or may be arranged partially in the horizontal direction and partially in the vertical direction. The models of the multiple battery cells 3 may be the same or different. That is, the positioning member 2 may be designed according to the specific arrangement structure of the battery cells 3 in the box body 1, thereby realizing various forms of arrangement and assembly, and improving the versatility of the battery 10.

[0047] Optionally, the positioning member 2 is configured as an integral structure with the box body 1. For example, the positioning member 2 can be integrally manufactured with the box body 1, or the positioning member 2 can be stamped by the box body 1 toward one side of the accommodating cavity, and the specific preparation process can be adjusted according to the specific structure of the box body 1.

[0048] See 1 and Figure 2 In some optional embodiments, the box body 1 includes a bottom wall and a side wall arranged around the bottom wall, the bottom wall and the side wall enclose a receiving cavity, and at least one of the bottom wall and the side wall is provided with a positioning member 2. By connecting the positioning member 2 to at least one of the bottom wall and the side wall of the box body 1 to form a partition cavity, there is no need to adjust the structure of the battery cell 3, thereby simplifying the difficulty of preparing the battery cell 3.

[0049] Optionally, the positioning member 2 can be set on one of the bottom wall and the side wall, and the positioning member 2 can also be set on the bottom wall and the side wall at the same time (not shown in the figure) to limit the surrounding side of the battery cell 3, further improve the limiting effect of the battery cell 3, and improve the reliability of the battery cell 3 assembled in the box body 1.

[0050] In some optional embodiments, multiple positioning members 2 are arranged at intervals along the first direction X, the positioning members 2 are set on the bottom wall and protrude a preset distance relative to the bottom wall along the second direction Z, two adjacent positioning members 2 and the bottom wall are enclosed to form a spacing cavity, and the second direction Z intersects with the first direction X.

[0051] That is, the positioning member 2 is arranged on the bottom wall and can have a preset height. On the one hand, after the battery pack is arranged in the compartment cavity, the positioning member can better limit the position of the battery pack, thereby improving the reliability of the assembled battery. On the other hand, the positioning member 2 can be enclosed together with the side wall of the box body 1 to form an overflow glue accommodating area, which can accommodate the glue overflowed during the extrusion and shaping process of the battery cell 3, thereby improving the overflow glue state.

[0052] See 1 and Figure 2 In some embodiments, each positioning member 2 has a preset thickness along the first direction X, and the battery 10 also includes a heat exchange structure 4, which is arranged corresponding to the positioning member 2 along the second direction Z, and the thickness of the heat exchange structure 4 along the first direction X is less than or equal to the thickness of the positioning member 2 along the first direction X.

[0053] Since the positioning member 2 serves to limit the battery pack, the positioning member 2 must have a certain thickness along the first direction X, so the space occupied by the thickness can be used to set the heat exchange structure 4, and the heat exchange structure 4 is used to achieve the cooling of the battery cell 3, so that the space inside the battery 10 can be more reasonably utilized to improve the energy density of the battery 10. Optionally, the heat exchange structure 4 can be set as an air cooling plate, a liquid cooling plate or an insulation pad to achieve the insulation and heat dissipation of the battery cell 3.

[0054] Furthermore, by making the thickness of the heat exchange structure 4 along the first direction X less than or equal to the thickness of the positioning member 2 along the first direction X, the mutual interference between the heat exchange structure 4 and the battery pack during installation can be reduced, so that the positioning member 2 can reliably abut against the surface of the battery pack along the first direction X, thereby achieving reliable positioning of the battery pack.

[0055] Optionally, the size of the positioning member 2 along the first direction X can be set to 3mm~10mm, and the size of the positioning member 2 along the second direction Z can be set to 0.5mm~5mm, so as to achieve reliable positioning of the battery cell 3 while reserving space for setting the heat exchange structure 4 to improve the reliability of the battery.

[0056] It can be understood that the battery cell 3 may have a central area and an edge area arranged around the central area, the heat exchange structure 4 is projected onto the battery cell 3 along the first direction X and is located in the central area, and the positioning member 2 is projected onto the battery cell 3 along the first direction X and is located in the edge area.

[0057] The central area and the edge area are specifically divided according to the battery cells. By setting the heat exchange structure 4 corresponding to the battery cells, the main heat generation area of ​​the battery cell 3 can be cooled to achieve the cooling of the battery 10, while the positioning member 2 corresponds to the periphery of the battery cell 3 to achieve the assembly positioning of the battery 10. Therefore, the area of ​​the positioning member 2 and the heat exchange structure 4 can be adjusted according to the actual structure of the battery cell 3 to take into account the assembly efficiency and cooling effect of the battery cell 3.

[0058] In some optional embodiments, one of the heat exchange structure 4 and the positioning member 2 is provided with a convex portion, and the other is provided with a concave portion, and the convex portion matches the concave portion to fix the heat exchange structure 4 in the accommodating cavity along the first direction X, thereby facilitating the positioning and assembly of the heat exchange structure 4 and improving the accuracy of battery assembly. In addition, the positioning member 2 can also simultaneously limit the battery pack and the heat exchange structure 4 to further improve the reliability of the battery after assembly.

[0059] It can be understood that during assembly, the heat exchange structure 4 can be assembled separately from the battery pack in the box body 1, or the heat exchange structure 4 can be connected to the battery pack and then assembled as a whole in the box body 1. Both can be adjusted according to actual assembly conditions, and the positioning assembly of the battery pack and the heat exchange structure 4 can be achieved through the positioning member 2.

[0060] See also Figure 3 Regarding the specific structure of the positioning member 2, in some optional embodiments, the positioning member 2 is continuously arranged along the third direction Y, and the third direction Y intersects with the second direction Z and the first direction X.

[0061] For the battery pack that is regularly arranged in the box body 1, for example, when the battery cells in the battery pack are arranged in the same direction and arranged along the first direction X, the positioning member 2 can be extended along the third direction Y, and multiple positioning members 2 can be arranged at intervals along the first direction X to form multiple compartments arranged along the first direction X corresponding to the battery cells 3. The positioning member 2 can be set as a strip structure, and the positioning member 2 can be extended from one end of the bottom wall to the other end along the third direction Y to simplify the setting structure of the positioning member 2.

[0062] See 4 and Figure 5 In some other optional embodiments, the positioning member 2 includes more than two positioning units 21, and the more than two positioning units 21 are arranged at intervals along the third direction Y. That is, the positioning member 2 can be set as a point structure, and the positioning member 2 is divided into multiple positioning units 21, so as to reduce the structural impact on the box body 1 while meeting the assembly positioning of the battery cell 3, reduce the weight of the box body 1, and improve the applicability of the battery.

[0063] Optionally, in the third direction Y, the ratio of the extension length of the positioning unit 21 to the distance between two adjacent positioning units 21 is 1 / 5 to 5. That is, when the positioning member 2 includes more than two positioning units 21, the ratio of the extension length of the positioning unit 21 along the third direction Y to the distance between two adjacent positioning units 21 can be adjusted to meet the assembly positioning of the battery cell 3.

[0064] See also Figure 6 In some optional embodiments, the battery pack includes more than two battery cells 3 along the third direction Y. Since the positioning member 2 is extended along the third direction Y, when the battery pack is laid out, the battery cells 3 in the battery pack can also be arranged along the third direction Y according to the extension length of the positioning member 2, so that multiple battery cells 3 are arranged along the third direction Y in the same compartment, thereby facilitating the assembly and arrangement of the battery.

[0065] In addition, along the first direction X, each battery pack includes one or two battery cells 3, and the battery packs and the compartments are arranged in a one-to-one correspondence.

[0066] When the battery pack includes only one battery cell 3, the number of battery cells 3 is the same as the number of compartments and they are respectively arranged in each compartment. By arranging the battery cells 3 and the compartments in a one-to-one correspondence, each battery cell 3 can be assembled and positioned, so that the battery cell 3 can be accurately assembled in the battery cell 3, thereby improving the reliability of the battery cell 3 being assembled in the box 1. In addition, both side surfaces of each battery cell 3 along the first direction X are in contact with the heat exchange structure 4, thereby improving the cooling effect on the battery cell 3 and further improving the reliability of the battery.

[0067] The shape and size of the partition cavity may correspond to each battery cell 3 , so that after each battery cell 3 is assembled in the partition cavity, each battery cell 3 can be limited by the box body 1 and the positioning member 2 , thereby improving the reliability of the battery cell 3 assembled in the box body 1 .

[0068] When the battery pack includes two battery cells 3, when the same number of battery cells 3 are installed, the number of positioning members 2 can be reduced, the volume of the battery can be reduced, and the battery energy density can be increased. In addition, each battery cell 3 can also have at least one surface in contact with the heat exchange structure 4 to achieve cooling of the battery cell 3.

[0069] It can be understood that each battery pack includes one or two battery cells 3, including each battery pack includes one battery cell 3, each battery pack includes two battery cells 3, and some battery packs include one battery cell 3 and other battery packs include two battery cells 3. The specific arrangement of the battery packs can be adjusted according to the actual structure of the battery, so as to achieve the positioning, assembly and cooling of each battery cell 3.

[0070] In some optional embodiments, the positioning member 2 is provided with a guide surface, which is inclined relative to the box body 1, and the battery cell 3 is introduced into the compartment cavity through the guide surface, thereby further improving the assembly efficiency and reducing the assembly difficulty.

[0071] Optionally, in order to form a guide surface, the cross-section of the positioning member 2 along the third direction Y can be set to be semicircular, trapezoidal, triangular, etc., and its specific shape can be adjusted according to the specific structure of the box body 1.

[0072] See also Figures 1 to 7 , the embodiment of the present application further provides an electric device, including a battery 10, which can be an energy storage device. The energy storage device includes an energy storage container, an energy storage cabinet, etc. The battery 10 is used to provide electric energy to the electric device, which can be a vehicle, a mobile phone, a portable device, a laptop computer, a ship, a spacecraft, an electric toy, an electric tool, etc. It should be understood that the technical solution described in the embodiment of the present application is applicable to all electric devices including the battery 10 and using the battery 10, but for the sake of simplicity, the following embodiments are all described by taking electric vehicles as examples.

[0073] Please refer to Figure 8 , Figure 8A schematic diagram of the structure of a vehicle provided for some embodiments of the present application. The vehicle 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 inside the vehicle, and the battery 10 may be provided at the bottom, head or tail of the vehicle. The battery 10 may be used to power the vehicle, for example, the battery 10 may be used as an operating power source for the vehicle. The vehicle 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 operating power requirements of the vehicle during driving.

[0074] In some embodiments, the box 1 can be used as a part of the chassis structure of the vehicle. For example, part of the box 1 can become at least a part of the floor of the vehicle, or part of the box 1 can become at least a part of the cross beam and longitudinal beam of the vehicle.
