For electric vehicles, battery technology is a key factor in their development.

[0005] With the continuous development of the power battery industry, the requirements for various battery performance are becoming higher and higher, resulting in the continuous increase in battery costs.

[0006] Summary of the Invention

[0007] In view of the above problems, the present application provides a battery and an electrical device that can reduce manufacturing costs.

[0008] In the first aspect, the present application provides a battery comprising: at least one battery pack, each of the battery packs comprising: a plurality of battery rows, each of the battery rows comprising a plurality of battery cells arranged along a first direction, the electrical connection portions of two adjacent battery cells of each battery row being connected by a first electrical connector, and the plurality of battery rows being arranged along a second direction; an information collection component, the information collection component being arranged on one side of the plurality of battery rows in a third direction, the third direction and the second direction being perpendicular to the first direction in pairs, the information collection component being electrically connected to the plurality of the first electrical connectors corresponding to at least two of the battery rows.

[0009] In the technical solution of the embodiment of the present application, multiple battery cells in each battery pack are connected to the information collection component through a first electrical connector to facilitate connection sampling of multiple battery cells and obtain information of each battery cell, etc., so that multiple battery rows in each battery pack can share one information collection component, thereby effectively reducing the number of information collection components in the battery, playing a role in reducing the manufacturing cost of the battery and enhancing the market competitiveness of the product.

[0010] In some embodiments, in each battery pack, the information acquisition component corresponds to a central position of the plurality of batteries arranged in the second direction. This technical solution facilitates connection of the information acquisition component to the plurality of first electrical connectors. Positioning the information acquisition component in the central position eliminates the need for bending the information acquisition component, minimizing its length and reducing its manufacturing cost.

[0011] In some embodiments, the information collection member extends along the first direction. In the above technical solution, by adopting the above arrangement structure, it is possible to facilitate the connection of the information collection member with the plurality of first electrical connectors, thereby improving the convenience of connection, while minimizing the length of the information collection member and reducing the manufacturing cost of the information collection member.

[0012] In some embodiments, the electrical connection portion includes a first electrical connection portion and a second electrical connection portion, the first electrical connection portion and the second electrical connection portion having opposite polarities, and the first electrical connection portion and the second electrical connection portion being located on the same side of the battery cell. In the above technical solution, the first electrical connector facilitates connecting the two connection portions of two adjacent battery cells with different polarities. The first electrical connector can be located on the side of the battery cell where the two electrical connections are located, and the information collection component can also be located on the same side, further improving connection convenience.

[0013] In some embodiments, in each battery row, the first electrical connection portion of one battery cell is connected to the second electrical connection portion of an adjacent battery cell via the first electrical connector. In the above technical solution, current transmission can be achieved while simultaneously accumulating the voltages in the battery row to achieve a desired output voltage.

[0014] In some embodiments, in each battery row, the first electrical connection portion of one battery cell and the second electrical connection portion of an adjacent battery cell are positioned correspondingly and connected via the first electrical connector, which extends along the first direction. In the above technical solution, current transmission between battery cells can be achieved. The first electrical connector extends along the front-to-back direction, facilitating the cooperation between the first electrical connector and the two connection portions. This shortens the length of the first electrical connector, reduces manufacturing costs, and at the same time ensures, to a certain extent, current transmission and stable voltage transmission between battery cells in the battery row.

[0015] In some embodiments, in each battery row, the first electrical connection portion of one battery cell and the second electrical connection portion of an adjacent battery cell are staggered in the first direction and connected by a first electrical connector, with the first electrical connector extending in a direction oblique to both the first and second directions. In the above technical solution, to achieve current transmission between two battery cells, the first electrical connector can be formed into a straight line, thereby simplifying its structure and facilitating its manufacture.

[0016] In some embodiments, in each battery row, at least two adjacent battery cells form a battery combination, the first electrical connection portions of the battery cells in each battery combination correspond to each other, the second electrical connection portions of the battery cells in each battery combination correspond to each other, and the first electrical connection portion of one battery combination is connected to the second electrical connection portion of an adjacent battery combination via the first electrical connector. In the above technical solution, on the basis of achieving current transmission, two adjacent battery cells can be connected in parallel, the capacities of the battery cells can be added together, and two adjacent groups of battery cells can be connected in series, and the voltages within the battery row can be added together to achieve the desired output voltage.

[0017] In some embodiments, in each battery row, the first electrical connection portion of one battery assembly corresponds to the second electrical connection portion of an adjacent battery assembly and is connected via the first electrical connector, which extends along the first direction. In the above technical solution, the two second electrical connections of the first battery assembly are connected to the two first electrical connections of the second battery assembly via the first electrical connector, enabling current transmission between the battery cells. The first electrical connector extends in the front-to-back direction, facilitating the coordination of the first electrical connector with the four connection portions. This shortens the length of the first electrical connector, reduces manufacturing costs, and at the same time ensures, to a certain extent, the stable transmission of current and voltage between the battery cells in the battery row.

[0018] In some embodiments, in each battery row, the first electrical connection portion of one battery assembly and the second electrical connection portion of an adjacent battery assembly are staggered in the first direction and connected by a first electrical connector, wherein the first electrical connector is bent. This technical solution facilitates connection between the first electrical connector and the electrical connection portions of the four battery cells, thereby enabling current transmission and series and parallel connection of the battery cells.

[0019] In some embodiments, in two adjacent battery rows, the first electrical connection portion of the battery cells at one end of the battery row is connected to the second electrical connection portion of the battery cells at one end of the adjacent battery row via a second electrical connector. In the above technical solution, the electrical connection between the battery row and the adjacent battery row is achieved, thereby connecting multiple battery rows together to provide greater energy storage capacity or increase output power.

[0020] In some embodiments, the battery cell includes a pressure relief portion, which is located on the same side of the battery cell as the electrical connector, and the projection of the pressure relief portion and the first electrical connector along the third direction do not overlap. In the above technical solution, by staggering the first electrical connector and the pressure relief portion, the reliability and stability of the battery cell can be enhanced, thereby avoiding safety hazards to a certain extent.

[0021] In some embodiments, the battery cell has a pressure relief portion, and the pressure relief portion and the electrical connection portion are located on different sides of the battery cell. In the above technical solution, the first and second electrical connectors that cooperate with the electrical connection portion do not interfere with the pressure relief portion, allowing high-pressure gas in the battery cell to be discharged through the pressure relief portion, thereby improving the effectiveness of the pressure relief portion's exhaust and enhancing the reliability and stability of the battery cell.

[0022] In some embodiments, the plurality of battery rows include a first battery row and a second battery row, the first battery row including a plurality of first battery cells, two adjacent first battery cells being connected via a first electrical connector, the second battery row being located to one side of the first battery row in the second direction and including a plurality of second battery cells, two adjacent second battery cells being connected via a first electrical connector, one first battery cell being connected to one second battery cell via a second electrical connector, and the information collection component being electrically connected to the plurality of first electrical connectors and second electrical connectors corresponding to the first battery row and the second battery row. In the above technical solution, it is possible to collect information of the plurality of battery cells in the first and second battery rows, such as temperature and voltage, thereby facilitating status monitoring of the battery cells.

[0023] In some embodiments, the information collecting component is directly connected to the first electrical connector. In the above technical solution, the number of components can be reduced, the manufacturing cost can be lowered, and the assembly operations can be reduced, thereby improving the assembly efficiency.

[0024] In some embodiments, one of the information acquisition component and the first electrical connector has a foot, and the other of the information acquisition component and the first electrical connector is connected to the foot. In the above technical solution, the provision of the foot facilitates the connection between the information acquisition component and the first electrical connector without significantly increasing the size of the information acquisition component or the first electrical connector, thereby reducing manufacturing costs.

[0025] In some embodiments, the information acquisition component and the first electrical connector are welded. In the above technical solution, by welding the two together, a reliable connection between the information acquisition component and the first electrical connector is achieved, and at the same time, the transmission of electrical signals can be achieved, the connection is convenient, and the assembly efficiency is improved.

[0026] In some embodiments, each battery pack further comprises a conductive member, through which the first electrical connector is connected to the information collection member. In the above technical solution, the conductive member may be a nickel sheet, which is a conductive material that can effectively transmit current and has good corrosion resistance.

[0027] In some embodiments, each battery pack further comprises a temperature acquisition module adapted to abut against the battery cells to acquire the temperature of the battery cells. This facilitates timely detection of temperature anomalies and the implementation of appropriate measures, such as heat dissipation or threshold alarms, to ensure the safety and performance of the battery cells.

[0028] In some embodiments, the temperature acquisition module is integrated into the information acquisition unit. In the above technical solution, by integrating the temperature acquisition module into the information acquisition unit, the temperature of the battery cell can be conveniently measured and recorded, and the temperature data can be processed and analyzed together with other parameter data. Thus, the information acquisition unit not only has the function of collecting other battery cell parameters, but also has the function of collecting battery cell temperature.

[0029] In some embodiments, the temperature acquisition module is integrated into the first electrical connector. In the above technical solution, by integrating the temperature acquisition module into the first electrical connector, the temperature of the battery cell can be conveniently measured and the temperature data can be transmitted to the battery management system or other monitoring equipment for real-time monitoring and analysis, thereby achieving immediate control of the battery cell temperature and timely response and management of abnormal temperature conditions. This allows the first electrical connector to both transmit current and acquire temperature, thus expanding the functionality of the first electrical connector.

[0030] In some embodiments, the information collection component is a flexible circuit board. In the above technical solution, by using a flexible circuit board, the situation where high-pressure gas cannot be discharged can be avoided to a certain extent, reducing safety hazards.

DETAILED DESCRIPTION

[0047] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0048] Unless otherwise defined, all technical and scientific terms used in this application have the same meanings as commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first" and "second" in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order or a primary-secondary relationship.

[0049] References to "embodiments" in this application mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments.

[0050] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connected," and "attached" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0051] The term "and / or" in this application simply describes an association between related objects, indicating that three possible relationships exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this application generally indicates that the related objects are in an "or" relationship.

[0052] In the embodiments of this application, the same reference numerals represent the same components, and for the sake of brevity, detailed descriptions of the same components in different embodiments are omitted. It should be understood that the thickness, length, width, and other dimensions of the various components in the embodiments of this application, as well as the overall thickness, length, width, and other dimensions of the integrated device shown in the drawings are merely illustrative and should not constitute any limitation on this application.

[0053] The term "plurality" used in this application refers to two or more (including two).

[0054] In this application, a battery refers to a single physical module that includes one or more battery cells to provide higher voltage and capacity. For example, the batteries mentioned in this application may include battery modules or battery packs. Some batteries may include a casing for enclosing one or more battery cells or multiple battery modules. The casing prevents liquids or other foreign matter from affecting the charging or discharging of the battery cells. Of course, some batteries may not include the above-mentioned casing and are directly installed in the battery installation compartment of the electrical device.

[0055] In this application, battery cells may include lithium-ion secondary batteries, lithium-ion primary batteries, lithium-sulfur batteries, sodium-lithium-ion batteries, sodium-ion batteries, or magnesium-ion batteries, etc., and the embodiments of this application do not limit this. Battery cells may be cylindrical, flat, rectangular, or other shapes, and the embodiments of this application do not limit this. Battery cells are generally divided into three types based on the packaging method: cylindrical battery cells, prismatic battery cells, and soft-pack battery cells, and the embodiments of this application do not limit this.

[0056] For example, a battery cell may include a housing, an electrode assembly, and an electrolyte, wherein the housing is used to contain the electrode assembly and the electrolyte. The electrode assembly is composed of a positive electrode sheet, a negative electrode sheet, and a separator. The battery cell mainly relies on the movement of metal ions between the positive electrode sheet and the negative electrode sheet to work. The positive electrode sheet includes a positive electrode collector and a positive electrode active material layer. The positive electrode active material layer is coated on the surface of the positive electrode collector. The positive electrode collector not coated with the positive electrode active material layer protrudes from the positive electrode collector coated with the positive electrode active material layer, and the positive electrode collector not coated with the positive electrode active material layer serves as the positive electrode tab. Taking lithium-ion batteries as an example, the material of the positive electrode collector can be aluminum, and the positive electrode active material can be lithium cobalt oxide, lithium iron phosphate, ternary lithium, or lithium manganese oxide, etc.

[0057] The negative electrode sheet consists of a negative current collector and a negative active material layer. The negative active material layer is coated on the surface of the negative current collector. The negative current collector uncoated with the negative active material layer protrudes from the negative current collector coated with the negative active material layer. The negative current collector uncoated with the negative active material layer serves as the negative electrode tab. The negative current collector can be made of copper, and the negative active material can be carbon, silicon, or other materials. To ensure that high currents can pass without melting, multiple positive electrode tabs are stacked together, and multiple negative electrode tabs are stacked together.

[0058] The material of the isolation film may be PP (polypropylene) or PE (polyethylene), etc. In addition, the electrode assembly may be a wound structure or a laminated structure, but the embodiments of the present application are not limited thereto.

[0059] Battery cells can be equipped with terminals and other components connected to the tabs, serving as electrical connections. Furthermore, they can have pressure relief features. When the internal pressure in a battery cell becomes excessive (e.g., due to thermal runaway), these features release substances (e.g., gas, liquid, particulate matter, etc.) from the cell to reduce the internal pressure. This prevents excessive internal pressure from causing dangerous accidents such as explosions. For example, these relief features can be explosion-proof valves, explosion-proof discs, and the like.

[0060] For example, as shown in Figures 1 and 2, some electrical devices 2000 are powered by batteries 1000. The battery 1000 includes a case 200 and a battery cell 11. The case 200 includes an upper shell 210 and a lower shell 220. The battery cell 11 is arranged in the case 200. As shown in Figures 3 and 4, the battery cell 11 has an electrical connection part and a pressure relief part 113. The electrical connection part includes a first electrical connection part 111 and a second electrical connection part 112, wherein the pressure relief part 113 and the electrical connection part can be located on the same side of the battery cell 11. As shown in Figure 3, the pressure relief part 113 is located between the first electrical connection part 111 and the second electrical connection part 112. As shown in Figure 4, the pressure relief part 113 is located on the same side of the first electrical connection part 111 and the second electrical connection part 112.

[0061] In order to ensure the various performances of the battery 1000, a sampling component is usually provided in the box 200. The sampling component is connected to the electrical connection part of the battery cell 11 and is used to collect signals from the battery cell 11, such as voltage, temperature, etc. The sampling component includes an information collection component 20. The cost of the information collection component 20 is relatively high. In traditional technology, one information collection component 20 is required for each row of battery cells 11 in the battery 1000. A large-capacity battery 1000 usually has multiple rows of battery cells 11. The demand for information collection components 20 is relatively large, which leads to a high manufacturing cost of the battery 1000.

[0062] To this end, the present application proposes a battery 1000 including at least one battery pack 100, each battery pack 100 including: multiple battery rows 10 and an information collection component 20, each battery row 10 including multiple battery cells 11 arranged along a first direction F1, in each battery row 10, the electrical connection parts of two adjacent battery cells 11 are connected by a first electrical connector 30, multiple battery rows 10 are arranged along a second direction F2, the information collection component 20 is provided on one side of the multiple battery rows 10 in a third direction F3, the third direction F3 and the second direction F2 are perpendicular to the first direction F1, and the information collection component 20 is electrically connected to the multiple first electrical connectors 30 corresponding to at least two battery rows 10.

[0063] In the battery 1000 of the above-mentioned structure, the multiple battery cells 11 in each battery pack 100 are connected to the information collection component 20 through the first electrical connector 30, so as to facilitate connection sampling of the multiple battery cells 11 and obtain information of each battery cell 11. As a result, the multiple battery rows 10 in each battery pack 100 can share one information collection component 20, thereby effectively reducing the number of information collection components 20 in the battery 1000, thereby reducing the manufacturing cost of the battery 1000 and improving the market competitiveness of the product.

[0064] The battery 1000 disclosed in the embodiment of the present application can be used in, but not limited to, an electrical device 2000 such as a vehicle, ship, or aircraft. The power supply system of the electrical device 2000 can be composed of the battery 1000 disclosed in the present application to ensure the safety and reliability of the electrical device 2000.

[0065] For example, the power-consuming device 2000 disclosed in the embodiments of the present application may be, but is not limited to, a vehicle, a mobile phone, a tablet, a laptop computer, a ship, a spacecraft, an electric toy, an electric tool, etc. A vehicle may be a fuel vehicle, a gas vehicle, a new energy vehicle, or a rail vehicle, and a new energy vehicle may be a pure electric vehicle, a hybrid vehicle, or an extended-range vehicle, etc.; a spacecraft includes an airplane, a rocket, a space shuttle, and a spacecraft, etc.; an electric toy includes a fixed or mobile electric toy, such as a game console, an electric vehicle toy, an electric ship toy, and an electric airplane toy, etc.; an electric tool includes a metal cutting electric tool, a grinding electric tool, an assembly electric tool, and a railway electric tool, such as an electric drill, an electric grinder, an electric wrench, an electric screwdriver, an electric hammer, an impact drill, a concrete vibrator, and an electric planer, etc.

[0066] Hereinafter, a battery 1000 according to an embodiment of the present application will be described with reference to the accompanying drawings.

[0067] As shown in Figures 5-12, Figure 5 shows a schematic diagram of a battery provided in some embodiments of the present application; Figures 6-12 show schematic diagrams of a battery pack 100 provided in some embodiments of the present application. As shown in Figure 5, the battery 1000 includes at least one battery pack 100, each battery pack 100 including: a plurality of battery rows 10 and an information acquisition unit 20. Each battery row 10 includes a plurality of battery cells 11 arranged along a first direction F1. In each battery row 10, the electrical connection portions of two adjacent battery cells 11 are connected by a first electrical connector 30. The plurality of battery rows 10 are arranged along a second direction F2. The information acquisition unit 20 is disposed on one side of the plurality of battery rows 10 in a third direction F3. The third direction F3 and the second direction F2 are perpendicular to the first direction F1. The information acquisition unit 20 is electrically connected to the plurality of first electrical connectors 30 corresponding to at least two battery rows 10.

[0068] As shown in Figure 5, the first direction F1 is the front-to-back direction, the second direction F2 is the left-to-right direction, and the third direction F3 is the up-down direction. As shown in Figure 5, the battery 1000 includes multiple battery packs 100, and each battery pack 100 includes multiple battery rows 10. Here, the number of battery rows 10 in each battery pack 100 can be two, or three or more, and the multiple battery rows 10 are arranged along the left-to-right direction.

[0069] Each battery row 10 includes a plurality of battery cells 11, and the plurality of battery cells 11 are arranged in the front-to-back direction. The battery cell 11 may include a shell, an electrode assembly and an electrolyte. The shell is used to accommodate the electrode assembly and the electrolyte. The electrode assembly consists of a positive electrode sheet, a negative electrode sheet and an isolation membrane. The electrical connection part is provided on the shell, and the electrical connection part can be connected to the electrode tab of the electrode assembly through an adapter. The battery cell 11 includes two electrical connection parts with different polarities to correspond to the positive electrode tab and the negative electrode tab.

[0070] The electrical connections of two adjacent battery cells 11 are connected via a first electrical connector 30, thereby connecting multiple battery cells 11 in a row and enabling the electrical connections of the battery cells 11 to be connected in series or in parallel. It is understood that the first electrical connector 30 can be an electrical connector of the same polarity connecting two battery cells 11 or an electrical connector of different polarity connecting two battery cells 11. The first electrical connector 30 can be flat or substantially flat, and can be made of aluminum, copper, or the like.

[0071] Of course, the battery 1000 may also include a battery pack 100 , which includes multiple battery rows 10 . The number of battery rows 10 in the battery pack 100 may be two, or three or more, and the multiple battery rows 10 are arranged in the left-right direction.

[0072] As shown in Figures 5 to 12, a battery pack 100 is provided with an information collection component 20, which is arranged above multiple battery rows 10. The information collection component 20 is electrically connected to multiple first electrical connectors 30 on the battery row 10, and then connected to the electrical connection part of the battery cell 11 through the first electrical connector 30, thereby realizing the collection of information of multiple battery cells 11 on the battery row 10, such as temperature or voltage collection. The end of the information collection component 20 can be connected to a connector 22, so that the signal collected by the information collection component 20 can be output through the connector 22, thereby facilitating the status monitoring of the battery cell 11.

[0073] As shown in FIG5 , an information collection component 20 is provided on multiple battery rows 10 of a battery pack 100, so that one information collection component 20 can correspond to two or more battery rows 10, that is, multiple battery rows 10 can share one information collection component 20. Compared with one battery row 10 corresponding to one information collection component 20, the number of information collection components 20 in the battery 1000 can be effectively reduced, the cost of the information collection component 20 can be reduced, and thus the manufacturing cost of the battery 1000 can be reduced.

[0074] In the above embodiment, the multiple battery cells 11 in each battery pack 100 are connected to the information collection component 20 through the first electrical connector 30, so as to facilitate connection sampling of the multiple battery cells 11 and obtain information of each battery cell 11. As a result, the multiple battery rows 10 in each battery pack 100 can share one information collection component 20, thereby effectively reducing the number of information collection components 20 in the battery 1000, thereby reducing the manufacturing cost of the battery 1000 and improving the market competitiveness of the product.

[0075] As shown in FIG. 5 to FIG. 12 , in some embodiments, in each battery pack 100 , the information acquisition component 20 corresponds to a middle position of the plurality of battery rows 10 in the second direction F2 .

[0076] As shown in Figures 5 and 6, the multiple battery rows 10 of a battery pack 100 are arranged in the left-right direction. In the left-right direction, the information acquisition component 20 is located in the middle of the multiple battery rows 10. The middle here can be the middle of the multiple battery rows 10 or a position close to the center of the multiple battery rows 10. As shown in Figure 6, the battery pack 100 includes two battery rows 10. The information acquisition component 20 can be located above the two battery rows 10, with a part of the information acquisition component 20 corresponding to one battery row 10 and the other part of the information acquisition component 20 corresponding to the other battery row 10; the information acquisition component 20 can also be located above one battery row 10 and adjacent to the other battery row 10.

[0077] By adopting the above-mentioned arrangement structure, the information collection component 20 can be easily connected to multiple first electrical connectors 30. The information collection component 20 is arranged in the middle, and there is no need to bend the information collection component 20, etc., so the length of the information collection component 20 can be reduced as much as possible, thereby reducing the manufacturing cost of the information collection component 20.

[0078] As shown in FIG. 6 to FIG. 12 , in some embodiments, the information collecting component 20 extends along a first direction F1 .

[0079] As shown in Figures 6 to 12, the information acquisition component 20 extends in the front-to-back direction, and the multiple battery cells 11 are arranged in the front-to-back direction. Therefore, the extension direction of the information acquisition component 20 is the same as the arrangement direction of the battery cells 11, which makes it easier for the information acquisition component 20 to cooperate with the first electrical connector 30 on the multiple battery cells 11, thereby improving the convenience of connection. At the same time, the information acquisition component 20 can be arranged in the middle of the multiple battery rows 10, and there is no need to bend the information acquisition component 20, etc., so as to minimize the length of the information acquisition component 20. The length of the information acquisition component 20 can be roughly the same as the total thickness of the multiple battery cells 11, thereby reducing the manufacturing cost of the information acquisition component 20.

[0080] In the above technical solution, by adopting the above arrangement structure, the information acquisition component 20 can be easily connected to multiple first electrical connectors 30, thereby improving the convenience of connection, while minimizing the length of the information acquisition component 20 as much as possible and reducing the manufacturing cost of the information acquisition component 20.

[0081] As shown in Figures 3-4 and Figures 6-12, in some embodiments, the electrical connection portion includes a first electrical connection portion 111 and a second electrical connection portion 112, the first electrical connection portion 111 and the second electrical connection portion 112 have opposite polarities, and the first electrical connection portion 111 and the second electrical connection portion 112 are located on the same side of the battery cell 11.

[0082] As shown in Figures 6 to 12, the battery cell 11 includes a first electrical connection portion 111 and a second electrical connection portion 112. The two connection portions have opposite polarities, that is, one is a positive pole and the other is a negative pole. At the same time, the first electrical connection portion 111 and the second electrical connection portion 112 are located on the same side of the battery cell 11, thereby facilitating the first electrical connector 30 to connect the two connection portions of two adjacent battery cells 11 with different polarities. The first electrical connector 30 can be arranged on the side of the battery cell 11 where the two electrical connection portions are provided, and the information collection component 20 can also be arranged on the same side to further improve the convenience of connection.

[0083] The following embodiments are described with the first electrical connection portion 111 being a positive electrode connection portion and the second electrical connection portion 112 being a negative electrode connection portion.

[0084] As shown in FIG. 6 to FIG. 8 , in some embodiments, in each battery row 10 , the first electrical connection portion 111 of one battery cell 11 is connected to the second electrical connection portion 112 of an adjacent battery cell 11 via a first electrical connector 30 .

[0085] As shown in Figures 6 to 8, in each battery row 10, the first electrical connection portion 111 of a battery cell 11 is connected to the second electrical connection portion 112 of an adjacent battery cell 11 through a first electrical connector 30, thereby realizing the series connection of each battery cell 11 in the battery row, that is, one first electrical connector 30 connects two battery cells 11, thereby realizing current transmission, and at the same time, the voltage in the battery row 10 can be accumulated to achieve the required output voltage.

[0086] As shown in FIG6 , in some embodiments, in each battery row 10 , the first electrical connection portion 111 of one battery cell 11 and the second electrical connection portion 112 of an adjacent battery cell 11 correspond in position, and the two electrical connection portions are connected by a first electrical connector 30 , which extends along a first direction F1 .

[0087] As shown in Figure 6, in each battery row 10, multiple battery cells 11 are arranged in the front-to-back direction, and the first electrical connection portion 111 of a battery cell 11 corresponds to the second electrical connection portion 112 of the adjacent battery cell 11. Taking the first battery cell 11 on the front side as an example, its first electrical connection portion 111 is located on the left side of the second electrical connection portion 112, and the rear side of its first electrical connection portion 111 is the second electrical connection portion 112 of another battery cell 11. Therefore, the first electrical connection portion 111 on the front side and the second electrical connection portion 112 on the rear side are connected through the first electrical connector 30 to realize the transmission of current between the battery cells 11. The first electrical connector 30 extends along the front-to-back direction to facilitate the cooperation between the first electrical connector 30 and the two connection portions, thereby shortening the length of the first electrical connector 30, reducing manufacturing costs, and at the same time ensuring the current transmission and stable voltage transmission between the battery cells 11 in the battery row 10 to a certain extent.

[0088] Among them, the first electrical connector 30 is connected to the information acquisition component 20, and the extension direction of the first electrical connector 30 and the information acquisition component 20 can be the same, thereby reducing the interference between the first electrical connector 30 and the information acquisition component 20, and improving the convenience and reliability of the connection. In addition, the connection between the first electrical connector 30 and the information acquisition component 20 can be a direct connection or an indirect connection, for example, through a conductive member 50, the first electrical connector 30 can extend a support leg toward the information acquisition component 20, and the support leg is connected to the information acquisition component 20, that is, the first electrical connector 30 forms a T-shape, thereby shortening the distance between the first electrical connector 30 and the information acquisition component 20, facilitating the connection between the two.

[0089] As shown in Figure 6, in some specific examples, each battery row 10 has two rows of first electrical connectors 30, the first row of first electrical connectors 30 are arranged at intervals along the first direction, and the first electrical connectors 30 in this row all form a straight line, the second row of first electrical connectors 30 are arranged at intervals along the first direction, and the first electrical connectors 30 in this row all form a T-shape, and the second row is located on the side of the first row away from the information collection component 20.

[0090] In some optional examples, the first row of first electrical connectors 30 can be connected to the information collection component 20 using the same conductive member 50, and the second row of first electrical connectors 30 can be connected to the information collection component 20 using the same conductive member 50, that is, the conductive member 50 connecting the first row of first electrical connectors 30 and the information collection component 20 can be a structural member of a uniform size, and the conductive member 50 connecting the second row of first electrical connectors 30 and the information collection component 20 can be a structural member of a uniform size, thereby reducing manufacturing costs and facilitating the connection between the conductive member 50 and each first electrical connector 30, thereby improving assembly efficiency.

[0091] As shown in Figures 7 and 8, in some embodiments, in each battery row 10, the first electrical connection portion 111 of a battery cell 11 and the second electrical connection portion 112 of an adjacent battery cell 11 are staggered in the first direction F1, and the two electrical connection portions are connected by a first electrical connector 30, and the extension direction of the first electrical connector 30 is inclined to the first direction F1 and the second direction F2.

[0092] As shown in Figures 7 and 8, in each battery row 10, multiple battery cells 11 are arranged in the front-to-back direction, and the first electrical connection portion 111 of each battery cell 11 is located on the same side of its second electrical connection portion 112 (the same side in the left-right direction). The two electrical connection portions of each battery cell 11 are arranged in the same manner, so that the electrical connection portions of the same polarity of two adjacent battery cells 11 are positioned opposite each other, and the first electrical connection portion 111 of one battery cell 11 and the second electrical connection portion 112 of the adjacent battery cell 11 are staggered.

[0093] Taking the first battery cell 11 on the front side of Figure 7 as an example, its first electrical connection portion 111 is located on the left side of the second electrical connection portion 112, and the rear side of its first electrical connection portion 111 is the first electrical connection portion 111 of another battery cell 11, and the second electrical connection portion 112 of the other battery cell 11 is located on the right side of the first electrical connection portion 111. The first electrical connection portion 111 on the front side is connected to the second electrical connection portion 112 on the rear side by a first electrical connector 30. The first electrical connector 30 extends gradually to the right from front to back, thereby realizing the transmission of current between the two battery cells 11. The first electrical connector 30 can form a straight line shape, thereby simplifying the structure of the first electrical connector 30 and facilitating the manufacturing and forming of the first electrical connector 30. On this battery row 10, each first electrical connector 30 extends in the same direction, and multiple first electrical connectors 30 are arranged at intervals along the front-to-back direction, thereby reducing the probability of interference between the first electrical connector 30 and other components and facilitating the connection between the first electrical connector 30 and the electrical connection portion.

[0094] In some optional examples, the first electrical connector 30 can be connected to the information acquisition component 20 using the same conductive member 50. That is, the conductive member 50 can be a structural member of uniform size. This can reduce manufacturing costs, facilitate the connection of the conductive member 50 to each first electrical connector 30, and improve assembly efficiency. Optionally, the extension direction of each conductive member 50 is inclined with respect to the first direction F1 and the second direction F2. Optionally, the extension direction of the conductive member 50 is perpendicular to the extension direction of the first electrical connector 30.

[0095] As shown in Figures 9-11, in some embodiments, in each battery row 10, at least two adjacent battery cells 11 form a battery combination 103, the first electrical connection portions 111 of the battery cells 11 in each battery combination 103 correspond in position, the second electrical connection portions 112 of the battery cells 11 in each battery combination 103 correspond in position, and the first electrical connection portion 111 of a battery combination 103 and the second electrical connection portion 112 of an adjacent battery combination 103 are connected via a first electrical connector 30.

[0096] As shown in Figures 9 to 11, in each battery row 10, two adjacent battery cells 11 form a battery combination 103, and the first electrical connection part 111 of two adjacent battery cells 11 and the second electrical connection part 112 of another two adjacent battery cells 11 are connected through a first electrical connector 30, that is, one first electrical connector 30 connects the corresponding electrical connection parts between four adjacent battery cells 11. On the basis of realizing the transmission of current, the parallel connection of two adjacent battery cells 11 can be realized, the capacity of the battery cells 11 can be superimposed, and at the same time, the two adjacent groups of battery cells 11 are connected in series, and the voltage in the battery row 10 is superimposed to achieve the required output voltage.

[0097] Of course, three adjacent battery cells 11 may form a battery assembly 103 , or more battery cells 11 may form a battery assembly 103 .

[0098] As shown in FIG9 , in some embodiments, in each battery row 10 , the first electrical connection portion 111 of one battery assembly 103 corresponds to the second electrical connection portion 112 of an adjacent battery assembly 103 and is connected via a first electrical connector 30 , which extends along a first direction F1 .

[0099] As shown in FIG9 , in each battery row 10 , two adjacent battery cells 11 form a battery combination 103 , and the first electrical connection portions 111 of the two battery cells 11 in each battery combination 103 correspond in position, and the first electrical connection portion 111 of each battery combination 103 corresponds in position to the second electrical connection portion 112 of the adjacent battery combination 103 and is connected through the first electrical connector 30 . Taking the front four battery cells 11 as an example, the front two battery cells 11 form the first battery combination 103 , whose first electrical connection portion 111 is located to the left of the second electrical connection portion 112 , and the rear two battery cells 11 form the second battery group The first electrical connection part 111 of the battery combination 103 is located on the right side of the second electrical connection part 112, so that the two second electrical connection parts 112 of the first battery combination 103 are connected with the two first electrical connection parts 111 of the second battery combination 103 through the first electrical connector 30, so as to realize the transmission of current between the battery cells 11. The first electrical connector 30 extends along the front-to-back direction to facilitate the cooperation between the first electrical connector 30 and the four electrical connection parts, thereby reducing the number of the first electrical connectors 30 and reducing the manufacturing cost, while ensuring the current transmission between the battery cells 11 in the battery row 10 and the stable transmission of voltage to a certain extent.

[0100] Among them, the first electrical connector 30 is connected to the information acquisition component 20, and the extension direction of the first electrical connector 30 and the information acquisition component 20 can be the same, thereby reducing the interference between the first electrical connector 30 and the information acquisition component 20, and improving the convenience and reliability of the connection. In addition, the connection between the first electrical connector 30 and the information acquisition component 20 can be a direct connection or an indirect connection, for example, through a conductive member 50, the first electrical connector 30 can extend a support leg toward the information acquisition component 20, and the support leg is connected to the information acquisition component 20, that is, the first electrical connector 30 forms a T-shape, thereby shortening the distance between the first electrical connector 30 and the information acquisition component 20, facilitating the connection between the two.

[0101] As shown in FIG9 , in some specific examples, each battery row 10 has two rows of first electrical connectors 30. The first row of first electrical connectors 30 are spaced apart along the first direction, each forming a straight line. The second row of first electrical connectors 30 are spaced apart along the first direction, each forming a T-shape. The second row is located on the side of the first row away from the information acquisition component 20. In some optional examples, the first row of first electrical connectors 30 can use the same conductive member 50 to connect to the information acquisition component 20, and the second row of first electrical connectors 30 can also use the same conductive member 50 to connect to the information acquisition component 20. That is, the conductive member 50 connecting the first row of first electrical connectors 30 to the information acquisition component 20 can be a structural member of the same size, and the conductive member 50 connecting the second row of first electrical connectors 30 to the information acquisition component 20 can also be a structural member of the same size. This can reduce manufacturing costs, facilitate the connection of the conductive member 50 to each first electrical connector 30, and improve assembly efficiency.

[0102] As shown in Figures 10 and 11, in some examples, in each battery row 10, the first electrical connection portion 111 of one battery combination 103 and the second electrical connection portion 112 of an adjacent battery combination 103 are staggered in a first direction F1 and connected by a first electrical connector 30, and the first electrical connector 30 is bent.

[0103] As shown in Figures 10 and 11, two adjacent battery cells 11 form a battery combination 103, the first electrical connection parts 111 of the two battery cells 11 in each battery combination 103 correspond in position, the second electrical connection parts 112 of the two battery cells 11 in each battery combination 103 correspond in position, the two electrical connection parts of each battery combination 103 are arranged in the same direction in the first direction F1, and the first electrical connection part 111 is located on the same side of its second electrical connection part 112, so that the first electrical connection part 111 of a battery combination 103 is staggered with the second electrical connection part 112 of the adjacent battery combination 103.

[0104] As shown in Figures 10 and 11, in each battery row 10, multiple battery cells 11 are arranged in the front-to-back direction, and the first electrical connection portion 111 of each battery cell 11 is located on the same side of its second electrical connection portion 112 (the same side in the left-right direction). The two electrical connection portions of each battery cell 11 are arranged in the same manner, so that the electrical connection portions of the same polarity of two adjacent battery cells 11 are positioned opposite each other, and the first electrical connection portion 111 of one battery cell 11 and the second electrical connection portion 112 of the adjacent battery cell 11 are staggered.

[0105] Taking the first battery cell 11 on the front side of Figure 10 as an example, its first electrical connection part 111 is located on the right side of the second electrical connection part 112, and the rear side of its first electrical connection part 111 is the first electrical connection part 111 of another battery cell 11. The second electrical connection part 112 of another battery cell 11 is located on the left side of the first electrical connection part 111. The two second electrical connection parts 112 on the front side and the two first electrical connection parts 111 on the rear side are connected through the first electrical connector 30, thereby realizing the transmission of current between the four battery cells 11.

[0106] The first electrical connector 30 is bent, such as in a Z shape, which facilitates connection between the first electrical connector 30 and the electrical connection portions of the four battery cells 11 , thereby achieving current transmission and series or parallel connection of the battery cells.

[0107] On a battery row 10, each first electrical connector 30 extends in the same direction, and multiple first electrical connectors 30 are arranged at intervals along the front-to-back direction, thereby reducing the probability of interference between the first electrical connector 30 and other components and facilitating the connection between the first electrical connector 30 and the electrical connection part.

[0108] As shown in Figures 10 and 11, in some embodiments, the first electrical connector 30 includes a first connecting segment 31, a second connecting segment 32 and a third connecting segment 33. The first connecting segment 31 connects the first electrical connecting portions 111 of two adjacent battery cells 11, and the third connecting segment 33 connects the second electrical connecting portions 112 of another two adjacent battery cells 11. The first connecting segment 31 and the third connecting segment 33 extend along the first direction F1 respectively, and the second connecting segment 32 is connected between the first connecting segment 31 and the third connecting segment 33. The extension direction of the second connecting segment 32 is inclined to the first direction F1 and the second direction F2, so that the first electrical connector 30 can connect the first electrical connecting portions 111 of two adjacent battery cells 11 and the second electrical connecting portions 112 of another two adjacent battery cells 11. At the same time, the size of the first electrical connector 30 can be reduced to a certain extent, the arrangement of the first electrical connector 30 can be optimized, and different design requirements can be met.

[0109] In some optional examples, the first connecting section 31 or the third connecting section 33 of the first electrical connector 30 can be connected to the information collection component 20 using the same conductive component 50, that is, the conductive component 50 can be a structural component of uniform size, thereby reducing manufacturing costs and facilitating the connection between the conductive component 50 and each first electrical connector 30, thereby improving assembly efficiency.

[0110] As shown in Figures 6-7 and Figures 9-10, in some embodiments, in two adjacent battery rows 10, the first electrical connection portion 111 of the battery cell 11 located at one end of the battery row 10 is connected to the second electrical connection portion 112 of the battery cell 11 at one end of the adjacent battery row 10 through the second electrical connector 40.

[0111] The second connecting member 40 may be in the shape of a flat plate or a substantially flat plate; the material of the second connecting member 40 may include aluminum, copper, etc.; the second connecting member 40 may be in the shape of a straight line or a U-shape.

[0112] By providing the second electrical connector 40 , the battery row 10 is electrically connected to the adjacent battery row 10 , thereby connecting multiple battery rows 10 together, thereby providing a larger electrical energy storage capacity or improving the output power.

[0113] In some examples, the first electrical connection portion 111 and the second electrical connection portion 112 of each battery cell 11 are arranged in the same direction. As shown in Figures 6-7 and Figures 9-10, the battery 1000 has two battery rows 10, and the two battery rows 10 are arranged in the left-right direction. The electrical connection portions of the battery cells 11 in the left battery row 10 are arranged in the same direction as the electrical connection portions of the battery cells 11 in the right battery row, that is, the first electrical connection portions 111 are both located on the same side of the second electrical connection portion 112. Taking the battery cell 11 shown in the front end of Figure 6 as an example, the first electrical connection portion 111 of the battery cell 11 in the left battery row 10 is located to the left of the second electrical connection portion 112, and the first electrical connection portion 111 of the battery cell 11 in the right battery row 10 is also located to the left of the second electrical connection portion 112. As a result, the second electrical connection portion 112 of the battery cell 11 in the left battery row 10 is adjacent to the first electrical connection portion 111 of the battery cell 11 in the right battery row 10, and the second electrical connector 40 By extending in the left and right directions, the two electrical connection parts can be connected, and the connection is convenient, thereby realizing the electrical connection between the battery row 10 and the adjacent battery row 10, thereby connecting multiple battery rows 10 together to provide a larger power storage capacity or increase the output power.

[0114] As shown in Figure 9, in some examples, the second electrical connector 40 can connect the first electrical connection portion 111 of two adjacent battery cells 11 and the second electrical connection portion 112 of two adjacent battery cells 11 to achieve electrical connection between two adjacent battery rows 10. At the same time, in each battery row 10, the first electrical connection portion 111 of two adjacent battery cells 11 and the second electrical connection portion 112 of another two adjacent battery cells 11 are connected through the first electrical connector 30, so that each electrical connector is connected to four battery cells 11 at the same time.

[0115] As shown in Figures 7 and 10, in some examples, the battery cell 11 has a pressure relief portion 113, which can be located on the same side of the two electrical connection portions of the battery cell 11. The electrical connection portions of two adjacent battery rows 10 can be arranged in the same direction, so that part of the pressure relief portion 113 is located between the electrical connection portions of the two battery rows 10. Therefore, the second electrical connector 40 can be designed to be bent, so that the second electrical connector 40 and the pressure relief portion 113 are staggered, thereby preventing the second electrical connector 40 from blocking the pressure relief portion 113 and affecting the discharge of gas during thermal runaway.

[0116] As shown in FIG. 8 and FIG. 11 , in some embodiments, in two adjacent battery rows 10 , the first electrical connection portions 111 and the second electrical connection portions 112 of the battery cells 11 are arranged in opposite directions.

[0117] As shown in Figures 8 and 11, the battery 1000 has two battery rows 10, which are arranged in the left and right directions. The electrical connection parts of the battery cells 11 of the left battery row 10 are arranged in opposite directions to the electrical connection parts of the battery cells 11 of the right battery row. The first electrical connection part 111 of the battery cell 11 in the left battery row 10 is located to the left of the second electrical connection part 112, and the first electrical connection part 111 of the battery cell 11 in the right battery row 10 is located to the right of the second electrical connection part 112. The second electrical connection part 112 of the battery cell 11 at the middle end of the left battery row 10 is connected to the first electrical connection part 111 of the battery cell 11 at the middle end of the right battery row 10 through the second electrical connector 40, thereby realizing electrical connection between the two adjacent battery rows 10.

[0118] As shown in Figures 8 and 11, in some embodiments, the battery cell 11 has a pressure relief portion 113, which can be located on the same side of the two electrical connection portions of the battery cell 11, and all the pressure relief portions 113 are located between the electrical connection portions of the two battery rows 10. At this time, the second electrical connector 40 can be designed to be bent so that the second electrical connector 40 and the pressure relief portion 113 are staggered to prevent the second electrical connector 40 from blocking the pressure relief portion 113 and affecting the discharge of gas during thermal runaway.

[0119] As shown in Figures 8 and 11, the second electrical connector 40 includes a fourth connecting segment 41, a fifth connecting segment 42 and a sixth connecting segment 43. The sixth connecting segment 43 connects the first electrical connection portion 111 of one or two battery cells 11, and the fourth connecting segment 41 connects the second electrical connection portion 112 of another or two other battery cells 11. The sixth connecting segment 43 and the fourth connecting segment 41 extend along the first direction F1 respectively. The fifth connecting segment 42 is connected between the sixth connecting segment 43 and the fourth connecting segment 41, and the fifth connecting segment 42 can extend along the second direction F2, so that the second electrical connector 40 can connect the two battery cells 11 of two adjacent battery rows 10. At the same time, the size of the second electrical connector 40 can be reduced to a certain extent, and the arrangement of the second electrical connector 40 can be optimized to meet different design requirements.

[0120] As shown in Figures 6 and 9, in some embodiments, the battery cell 11 has a pressure relief portion 113, the pressure relief portion 113 and the electrical connection portion are located on the same side of the battery cell 11, and the pressure relief portion 113 is located between the first electrical connection portion 111 and the second electrical connection portion 112, and the projection of the pressure relief portion 113 on the plane where the first electrical connector 30 is located is located on the outside of the first electrical connector 30.

[0121] The pressure relief portion 113 is a component used to release the battery pressure when the internal pressure of the battery cell 11 is too high. The pressure relief portion 113 can be an explosion-proof valve or an explosion-proof disk.

[0122] As shown in Figures 6 and 9, the pressure relief portion 113 and the two electrical connection portions are all located on the upper side of the battery cell 11, and the pressure relief portion 113 is located between the first electrical connection portion 111 and the second electrical connection portion 112. In the up and down directions, the pressure relief portion 113 and the first electrical connector 30 are staggered. As a result, when thermal runaway occurs in the battery cell 11, high-pressure gas can be discharged through the pressure relief portion 113, preventing the first electrical connector 30 from blocking the pressure relief at the pressure relief portion 113 and affecting the discharge of high-pressure gas.

[0123] It should be noted that the information collection component 20 is usually a flexible component with low structural strength. Even if the information collection component 20 is located above the pressure relief portion 113 and partially blocks the pressure relief valve 113, when thermal runaway occurs in the battery cell 11, the high-pressure gas can be discharged through the pressure relief portion 113. At the same time, the high-pressure gas can break through the information collection component 20, thereby ensuring the smooth discharge of the high-pressure gas to a certain extent.

[0124] In the above technical solution, by staggering the first electrical connector 30 and the pressure relief portion 113 , the reliability and stability of the battery cell 10 can be enhanced, and potential safety hazards can be avoided to a certain extent.

[0125] As shown in Figures 7-8 and 10-11, in some embodiments, the battery cell 11 has a pressure relief portion 113, the pressure relief portion 113 and the electrical connection portion are located on the same side of the battery cell 11, and the pressure relief portion 113 is located on the same side of the first electrical connection portion 111 and the second electrical connection portion 112 in the second direction F2, and the projection of the pressure relief portion 113 on the plane where the first electrical connector 30 is located is located on the outside of the first electrical connector 30.

[0126] As shown in Figures 7-8 and 10-11, the pressure relief portion 113 and the two electrical connection portions are all located on the upper side of the battery cell 11. The pressure relief portion 113 is located on the same side of the first electrical connection portion 111 and the second electrical connection portion 112 (the right side as shown in Figure 7). In the up and down directions, the pressure relief portion 113 and the first electrical connector 30 are staggered. Therefore, when thermal runaway occurs in the battery cell 11, high-pressure gas can be discharged through the pressure relief portion 113, preventing the first electrical connector 30 from blocking the pressure relief at the pressure relief portion 113 and affecting the discharge of high-pressure gas.

[0127] It should be noted that the information collection component 20 is usually a flexible component with low structural strength. Even if the information collection component 20 is located above the pressure relief portion 113 and partially blocks the pressure relief valve 113, when thermal runaway occurs in the battery cell 11, the high-pressure gas can be discharged through the pressure relief portion 113. At the same time, the high-pressure gas can break through the information collection component 20, thereby ensuring the smooth discharge of the high-pressure gas to a certain extent.

[0128] In the above technical solution, by staggering the first electrical connector 30 and the pressure relief portion 113 , the reliability and stability of the battery cell 10 can be enhanced, and potential safety hazards can be avoided to a certain extent.

[0129] In some embodiments, the battery cell 11 has a pressure relief portion 113 , and the pressure relief portion 113 and the electrical connection portion are located on different sides of the battery cell 11 .

[0130] The upper side of the battery cell 11 has a first electrical connection portion 111 and a second electrical connection portion 112, and the pressure relief portion 113 is located on the lower side of the battery cell 11. As a result, the pressure relief portion 113 and the electrical connection portion are located on different sides of the battery cell 11. At this time, the first electrical connector 30 and the second electrical connector 40 that cooperate with the electrical connection portion do not interfere with the pressure relief portion 113, allowing the high-pressure gas in the battery cell 11 to be discharged through the pressure relief portion 113, thereby improving the effectiveness of the pressure relief portion 113 in exhausting and improving the reliability and stability of the battery cell. Of course, the pressure relief portion 113 can also be located on the left or right side of the battery cell 11, and the electrical connection portion is located on the upper or lower side of the battery cell 11, so that the pressure relief portion 113 and the electrical connection portion are located on different sides of the battery cell 11.

[0131] As shown in Figures 6 to 12, in some embodiments, multiple battery rows 10 include a first battery row 101 and a second battery row 102, the first battery row 101 includes multiple first battery cells, and two adjacent first battery cells are connected by a first electrical connector 30, the second battery row 102 is located on one side of the first battery row 101 in the second direction F2, the second battery row 102 includes multiple second battery cells, and two adjacent second battery cells are connected by a first electrical connector 30, one first battery cell is connected to one second battery cell by a second electrical connector 40, and the information collection component 20 is electrically connected to the multiple first electrical connectors 30 and second electrical connectors 40 corresponding to the first battery row 101 and the second battery row 102.

[0132] As shown in Figures 6 to 12, the first battery row 101 is located on the left side of the second battery row 102. The first battery row 101 includes a plurality of first battery cells, and two adjacent first battery cells are connected by a first electrical connector 30. The second battery row 102 includes a plurality of second battery cells, and two adjacent second battery cells are connected by a first electrical connector 30. It can be understood that, as shown in Figures 6 to 8 and 12, the first electrical connector 30 can connect two adjacent battery cells. In this case, the second electrical connector 40 connects one first battery cell and one second battery cell, thereby connecting the plurality of battery cells 11 of the first battery row 101 and the second battery row 102 in series; as shown in Figures 9 to 11, the first electrical connector 30 can also connect four adjacent battery cells. In this case, the second electrical connector 40 connects two first battery cells and two second battery cells, thereby connecting the plurality of battery cells 11 of the first battery row 101 and the second battery row 102 in parallel and series.

[0133] Multiple first electrical connectors 30 are connected to the information collection component 20, and the second electrical connector 40 is connected to the information collection component 20, thereby realizing the collection of information of multiple battery cells 11 on the first battery row 101 and the second battery row 102, such as temperature or voltage collection, thereby facilitating the status monitoring of the battery cells 11.

[0134] Of course, the battery pack 10 can also have a third battery row, a fourth battery row, etc. By adjusting the position of the electrical connection part and the pressure relief part 113 of the battery cell 11, and adjusting the spacing between the first electrical connection part 111 and the second electrical connection part 112, one information collection component 20 can be used on multiple battery rows, thereby effectively reducing the number of information collection components 20 in the battery 1000 and reducing manufacturing costs.

[0135] As shown in FIG. 12 , in some embodiments, the information acquisition component 20 and the first electrical connection component 30 are directly connected.

[0136] As shown in FIG12 , the information acquisition component 20 is directly connected to the first electrical connector 30 , thereby reducing parts and components, lowering manufacturing costs, and reducing assembly actions and improving assembly efficiency; of course, the second electrical connector 40 can also be directly connected to the information acquisition component 20 .

[0137] As shown in FIG. 12 , in some embodiments, one of the information acquisition component 20 and the first electrical connection component 30 has a support leg 21 , and the other of the information acquisition component 20 and the first electrical connection component 30 is connected to the support leg 21 .

[0138] As shown in Figure 12, the information collection component 20 has a support foot 21, which can extend to the first electrical connector 30 so that the support foot 21 partially overlaps with the first electrical connector 30. Then, the information collection component 20 and the first electrical connector 30 can be connected by connecting the support foot 21 to the first electrical connector 30. By setting the support foot 21, the connection between the information collection component 20 and the first electrical connector 30 is facilitated without increasing the size of the information collection component 20 or the first electrical connector 30 too much, thereby reducing the manufacturing cost.

[0139] Of course, the first electrical connector 30 may also have a foot extending toward the information acquisition component 20 , and the information acquisition component 20 is connected to the foot of the first electrical connector 30 , or the foot 21 of the information acquisition component 20 is connected to the foot of the first electrical connector 30 .

[0140] Of course, in the embodiments shown in FIG. 6 to FIG. 11 , the information collecting component 20 and the first electrical connector 30 may also be directly connected, thereby eliminating the conductive component 50 in the figure and reducing manufacturing costs.

[0141] As shown in Figure 12, in some embodiments, the information acquisition component 20 and the first electrical connector 30 are welded. For example, the information acquisition component 20 has a support leg 21, and the support leg 21 is integrally formed on the information acquisition component 20. The support leg 21 is welded to the first electrical connector 30. By connecting the two by welding, a reliable connection between the information acquisition component 20 and the first electrical connector 30 is achieved, and the transmission of electrical signals can be achieved at the same time. The connection is convenient, and the assembly efficiency is improved.

[0142] In addition, the information collecting component 20 may also be directly connected to the second electrical connector 40 . For example, the information collecting component 20 may have a support leg 21 , and the support leg 21 may be welded to the second electrical connector 40 .

[0143] As shown in FIG. 6 to FIG. 11 , in some embodiments, each battery pack 100 further includes a conductive member 50 , and the first electrical connector 30 is connected to the information acquisition member 20 via the conductive member 50 .

[0144] As shown in Figures 6-11 , the first electrical connector 30 and the information acquisition component 20 are spaced apart and connected via a conductive member 50. One end of the conductive member 50 is connected to the first electrical connector 30, and the other end is connected to the information acquisition component 20. The conductive member 50 may be a nickel sheet, a conductive material that effectively transmits current and exhibits excellent corrosion resistance. The conductive member 50 can be welded to the first electrical connector 30 and the information acquisition component 20, respectively, providing convenient and reliable connections. Furthermore, the second electrical connector 40 can also be connected to the information acquisition component 20 via the conductive member 50.

[0145] In some embodiments, each battery pack 100 further includes a temperature acquisition module, which may abut against the battery cell 11 to acquire the temperature of the battery cell 11 .

[0146] Each battery pack 100 includes one or more temperature acquisition modules. The temperature acquisition module is a device for monitoring and recording the temperature of the battery cells. The temperature acquisition module can monitor and control the temperature of the battery cells in real time so as to promptly detect temperature anomalies and take appropriate measures, such as heat dissipation or threshold alarms, to ensure the safety and performance of the battery cells 11.

[0147] The temperature acquisition module is in contact with one or more battery cells 11 to obtain accurate temperature data, thereby enabling timely detection of abnormal conditions such as overheating.

[0148] In some examples, the temperature acquisition module is integrated into the information acquisition component 20 .

[0149] By integrating the temperature acquisition module into the information acquisition component 20, the temperature of the battery cell 11 can be conveniently measured and recorded, and the temperature data can be processed and analyzed together with other parameter data; thus, the information acquisition component 20 not only has the function of collecting other battery cell parameters, but also has the function of collecting the temperature of the battery cell 11.

[0150] In some embodiments, the temperature acquisition module is integrated on the first electrical connector 30 .

[0151] By integrating the temperature acquisition module on the first electrical connector 30, the temperature of the battery cell 11 can be conveniently measured, and the temperature data can be transmitted to the battery management system or other monitoring equipment for real-time monitoring and analysis, thereby achieving instant control of the temperature of the battery cell 11 and timely response and management of abnormal temperature conditions; thereby, the first electrical connector 30 can both transmit current and collect temperature, expanding the function of the first electrical connector 30.

[0152] In addition, a temperature acquisition module may also be integrated on the second electrical connector 40 to expand the function of the second electrical connector 40. Of course, the temperature acquisition module may also be integrated on the conductive member 50.

[0153] In some embodiments, the information collection component 20 is a flexible printed circuit (FPC), which is a flexible printed circuit. A flexible printed circuit is a circuit board made of a flexible substrate. It has flexibility and plasticity, and the rigidity of the flexible circuit board is relatively low. Therefore, even if the flexible circuit board is arranged above the pressure relief portion 113, when the battery cell 11 has thermal runaway, the high-pressure gas is discharged through the pressure relief portion 113, which can break through the flexible circuit board and then be discharged to the outside of the battery 1000 through the exhaust channel, so as to quickly discharge the high-pressure gas and reduce the risk of gas accumulation. Therefore, the use of a flexible circuit board can avoid the situation where the high-pressure gas cannot be discharged to a certain extent, thereby reducing safety hazards.

[0154] According to the second embodiment of the present application, the power device 2000 includes the battery 1000 according to the first embodiment of the present application, and the battery 1000 is used to provide power to the power device 2000. Therefore, by using the above-mentioned battery 1000, the safety and reliability of the power device 2000 are improved.

[0155] Optionally, as shown in FIG1 , when battery 1000 is used in a vehicle, it can be located at the bottom, front, or rear of the vehicle. Battery 1000 can be used to power the vehicle, for example, as an operating power source for the vehicle. The vehicle can also include a controller and a motor, with the controller controlling battery 1000 to power the motor, for example, to meet the vehicle's starting, navigation, and operating power requirements during driving.

[0156] A battery 1000 and a vehicle having the same according to a specific embodiment of the present application will be described below with reference to the accompanying drawings.

[0157] As shown in Figure 1, the battery 1000 is arranged at the bottom of the vehicle, and as shown in Figures 5-6, the battery 1000 includes multiple battery packs 100, which are arranged in the left and right directions. Each battery pack 100 includes two battery rows 10 and an information collection component 20, namely a first battery row 101 and a second battery row 102. The first battery row 101 is arranged on the left side of the second battery row 102.

[0158] The first battery row 101 includes multiple first battery cells, each of which has a first electrical connection portion 111 and a second electrical connection portion 112 with different polarities, and a pressure relief portion 113 is provided between the first electrical connection portion 111 and the second electrical connection portion 112. The first electrical connection portion 111 of one battery cell 11 corresponds to the second electrical connection portion 112 of an adjacent battery cell 11, that is, the positive and negative poles are arranged alternately, and the two electrical connection portions of the two battery cells 11 with different polarities are connected by a first electrical connector 30.

[0159] The second battery row 102 includes a plurality of second battery cells, each of which has a first electrical connection portion 111 and a second electrical connection portion 112 with different polarities. A pressure relief portion 113 is provided between the first electrical connection portion 111 and the second electrical connection portion 112. The first electrical connection portion 111 of one battery cell 11 corresponds to the second electrical connection portion 112 of an adjacent battery cell 11, i.e., the positive and negative poles are arranged alternately. The two electrical connection portions of the two battery cells 11 with different polarities are connected by a first electrical connector 30. The electrical connection portions of the second battery row 102 and the first battery row 101 are arranged in the same direction.

[0160] The first electrical connection portion 111 of the first battery cell is connected to the second electrical connection portion 112 of the second battery cell via the second electrical connector 40 , thereby achieving electrical connection within each battery pack 100 .

[0161] The information acquisition component 20 is a flexible circuit board. The information acquisition component 20 is arranged above the first battery row 101 and the second battery row 102, and in the horizontal direction, the information acquisition component 20 is located in the middle of the entire battery pack 100. The information acquisition component 20 is connected to the first electrical connector 30 and the second electrical connector 40 through a conductive member 50, so that the two rows of battery cells 11 in the same battery row 10 share one information acquisition component 20. The information acquisition component 20 is integrated with a temperature detection module.

[0162] In the above embodiment, the number of information acquisition components 20 in the battery 1000 can be effectively reduced, thereby reducing the manufacturing cost of the battery 1000 and improving the market competitiveness of the product.
