[0032] To clarify the purpose, technical proposal, and advantages of the embodiments of this application, the following clearly describes the technical proposal in the embodiments of this application, linking it with the drawings of the embodiments. Clearly, the embodiments described are only some, not all, embodiments of this application. All other embodiments derived from the embodiments of this application without the creative effort of a person skilled in the art are all within the scope of protection of this application.

[0033] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as that commonly understood by those skilled in the art relating to this application. In this application, terms used in the specification are solely for the purpose of describing specific embodiments and are not intended to limit this application. The terms “includes” and “have,” and any variations thereof, in the description of the specification, claims, and drawings of this application are intended to intentionally cover the non-exclusive “includes.” Terms such as “first,” “second,” etc., in the specification, claims, or drawings of this application are not intended to describe a particular order or hierarchical relationship, but to distinguish different subjects.

[0034] The “Examples” as used in this application mean that certain features, structures, or characteristics described in conjunction with the Examples may be included in at least one Example of this application. The occurrence of this phrase in each location in the specification does not necessarily refer to the same Example, nor does it mean that each Example is mutually exclusive or alternative to the others.

[0035] In the description of this application, unless otherwise specifically defined or limited, the terms “attachment,” “connection,” “connection,” and “installation” should be understood in a broad sense. For example, a fixed connection may be a detachable connection, an integral connection, a direct connection, an indirect connection via an intermediate medium, or internal communication between two elements. A person skilled in the art will be able to understand the specific meaning of these terms in this application depending on the specific circumstances.

[0036] In this application, the terms "and / or" merely describe the relationship between related objects, indicating that three relationships are possible. For example, A and / or B may represent three cases: A alone, a combination of A and B, or B alone. In this application, the character " / " generally indicates that the preceding and succeeding related objects are in an "or" relationship.

[0037] In the embodiments of this application, the same reference numerals indicate the same component, and for the sake of brevity, detailed descriptions of the same component are omitted in different embodiments. It should be understood that the dimensions such as thickness, aspect ratio of various components in the embodiments of this application shown in the drawings, and the dimensions such as thickness, aspect ratio of the overall assembly device, are illustrative only and do not constitute any limitation of this application.

[0038] As used in this application, "multiple" refers to two or more (including two).

[0039] In this application, "battery" refers to a single physical module containing one or more battery cells to provide higher voltage and capacity. For example, the batteries referred to in this application may include battery modules or battery packs. Some batteries may include a housing for packaging one or more battery cells or multiple battery modules. The housing can prevent liquids or other foreign matter from affecting the charging or discharging of the battery cells. Of course, some batteries do not include the housing and are installed directly in the battery mounting cabin of a power consumption device.

[0040] In this application, the battery cell may include lithium-ion secondary batteries, lithium-ion primary batteries, lithium-sulfur batteries, sodium-lithium-ion batteries, sodium-ion batteries, or magnesium-ion batteries, and the embodiments of this application are not limited thereto. The battery cell may be cylindrical, flattened, rectangular, or have other shapes, and the embodiments of this application are not limited thereto. Generally, battery cells are classified into three types based on their packaging: cylindrical battery cells, rectangular battery cells, and pouch battery cells, and the embodiments of this application are not limited thereto.

[0041] For example, a battery cell may include a housing, an electrode assembly, and an electrolyte, the housing being used to house the electrode assembly and the electrolyte. The electrode assembly consists of a positive electrode plate, a negative electrode plate, and a separator. The battery cell operates primarily through the movement of metal ions between the positive and negative electrode plates. The positive electrode plate includes a positive electrode current collector and a positive electrode active material layer, the positive electrode active material layer being coated on the surface of the positive electrode current collector, a positive electrode current collector without the positive electrode active material layer protruding from a positive electrode current collector with the positive electrode active material layer, and a positive electrode current collector without the positive electrode active material layer being a positive electrode tab. Taking a lithium-ion battery as an example, the material of the positive electrode current collector may be aluminum, and the positive electrode active material may be lithium cobalt oxide, lithium iron phosphate, ternary lithium, or lithium manganese oxide, etc.

[0042] The negative electrode plate includes a negative electrode current collector and a negative electrode active material layer. The negative electrode active material layer is coated on the surface of the negative electrode current collector. A negative electrode current collector without the negative electrode active material layer protrudes from a negative electrode current collector with the negative electrode active material layer, and a negative electrode current collector without the negative electrode active material layer is designated as a negative electrode tab. The material of the negative electrode current collector may be copper, and the negative electrode active material may be carbon or silicon, etc. Multiple positive electrode tabs are stacked to prevent melting even when a large current is applied. Multiple negative electrode tabs are stacked.

[0043] The separator material may be PP (polypropylene) or PE (polyethylene), etc. The electrode assembly may have a wound structure or a laminated structure, and the embodiments of this application are not limited to these.

[0044] A pole or similar component may be installed in the battery cell and connected to a tab, serving as the electrical connection point of the battery cell. Furthermore, the battery cell may have a pressure relief section. If the internal pressure of the battery cell becomes too high (e.g., thermal runaway), the pressure relief section is used to release substances (e.g., gas, liquid, particulate matter, etc.) inside the battery cell to reduce the internal pressure, thereby preventing dangerous accidents such as the battery cell exploding due to rapid pressurization. For example, the pressure relief section may be an explosion-proof valve, an explosion-proof sheet, etc.

[0045] For example, as shown in Figures 1 and 2, several power consumption devices 2000 are powered using a battery 1000, the battery 1000 includes a housing 200 and a battery cell 11, the housing 200 includes an upper case 210 and a lower case 220, the battery cell 11 is provided inside the housing 200, and 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, here the pressure relief part 113 and the electrical connection part may 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, and 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.

[0046] To ensure the performance of each aspect of the battery 1000, a sampling assembly is generally provided within the housing 200. The sampling assembly is connected to the electrical connections of the battery cells 11 and is used to collect signals from the battery cells 11, such as voltage and temperature. The sampling assembly includes an information collection member 20, which is relatively expensive. In the prior art, it is necessary to install one information collection member 20 for each row of battery cells 11 in the battery 1000. Large-capacity batteries 1000 generally have multiple rows of battery cells 11, resulting in a relatively large demand for information collection members 20, which in turn increases the manufacturing cost of the battery 1000.

[0047] Therefore, this application proposes that the battery 1000 includes at least one battery pack 100, each battery pack 100 including a plurality of battery rows 10 and an information gathering member 20, each battery row 10 including a plurality of battery cells 11 arranged along a first direction F1, in each battery row 10 the electrical connections of two adjacent battery cells 11 are connected by a first electrical connection member 30, the plurality of battery rows 10 are arranged along a second direction F2, the information gathering member 20 is provided 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 two perpendicular to the first direction F1, and the information gathering member 20 is electrically connected to a plurality of first electrical connection members 30 corresponding to at least two battery rows 10.

[0048] In a battery 1000 with the structure described above, multiple battery cells 11 within each battery pack 100 are connected to an information collection member 20 by a first electrical connection member 30, facilitating connection sampling for multiple battery cells 11 and acquiring information about each battery cell 11. As a result, multiple battery rows 10 within each battery pack 100 can share a single information collection member 20, effectively reducing the number of information collection members 20 within the battery 1000, thereby lowering the manufacturing cost of the battery 1000 and improving the market competitiveness of the product.

[0049] The battery 1000 disclosed in the embodiments of this application can be used in a power consumption device 2000 such as a vehicle, ship, or aircraft, but is not limited to these uses. The power supply system of the power consumption device 2000 can be configured with the battery 1000 disclosed in this application, etc., to ensure the safety and reliability of the power consumption device 2000.

[0050] For example, the power consumption device 2000 disclosed in the embodiments of this application may be, but is not limited to, a vehicle, mobile phone, tablet, laptop computer, ship, spacecraft, electric toy, and power tool. A vehicle may be a fuel vehicle, or a gas vehicle, or a new energy vehicle, or a railway vehicle, and a new energy vehicle may be a pure electric vehicle, a hybrid vehicle, or a range extender vehicle, etc. Spacecraft include airplanes, rockets, space shuttles, and spacecraft, etc. Electric toys include stationary or mobile electric toys, such as game consoles, electric vehicle toys, electric ship toys, and electric airplane toys, etc. Power tools include metal cutting power tools, grinding power tools, assembly power tools, and railway power tools, such as electric drills, electric grinders, electric wrenches, electric screwdrivers, electric hammers, electric impact drills, concrete vibrators, and electric planers, etc.

[0051] The following describes the battery 1000 according to the embodiment of this application, with reference to the drawings.

[0052] As shown in Figures 5-12, Figure 5 shows a schematic diagram of a battery according to some embodiments of the present application, and Figures 6-12 show schematic diagrams of a battery pack 100 according to 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 gathering member 20, each battery row 10 including a plurality of battery cells 11 arranged along a first direction F1, in each battery row 10 the electrical connection between two adjacent battery cells 11 is connected by a first electrical connection member 30, the plurality of battery rows 10 are arranged along a second direction F2, the information gathering member 20 is provided 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 two perpendicular to the first direction F1, and the information gathering member 20 is electrically connected to a plurality of first electrical connection members 30 corresponding to at least two battery rows 10.

[0053] As shown in Figure 5, the first direction F1 is the front-back direction, the second direction F2 is the left-right direction, and the third direction F3 is the up-down direction. As shown in Figure 5, the battery 1000 includes a plurality of battery packs 100, each battery pack 100 includes a plurality of battery rows 10, where the number of battery rows 10 in each battery pack 100 may be two or three or more, and the plurality of battery rows 10 are arranged along the left-right direction.

[0054] Each battery row 10 includes a plurality of battery cells 11, which are arranged along the front-to-back direction. The battery cells 11 may include a housing, an electrode assembly, and an electrolyte. The housing is used to house the electrode assembly and the electrolyte. The electrode assembly consists of a positive electrode plate, a negative electrode plate, and a separator. Electrical connections are provided in the housing, and the electrical connections may be connected to tabs on the electrode assembly by an adapter sheet. The battery cell 11 includes two electrical connections with different polarities, connecting the positive electrode tab and the negative electrode tab in correspondence.

[0055] Here, the electrical connections of two adjacent battery cells 11 are connected by a first electrical connecting member 30, thereby connecting multiple battery cells 11 in a line and realizing series or parallel connection of the electrical connections of the battery cells 11. As can be understood, the first electrical connecting member 30 here may be an electrical connection of the same polarity connecting two battery cells 11, or an electrical connection of different polarities connecting two battery cells 11. The first electrical connecting member 30 may be flat or substantially flat, and the material of the first electrical connecting member 30 may include aluminum, copper, etc.

[0056] Of course, the battery 1000 may include a single battery pack 100, which includes multiple battery rows 10, the number of battery rows 10 in the battery pack 100 may be two, three or more, and the multiple battery rows 10 are arranged along the left-right direction.

[0057] As shown in Figures 5-12, one information collection member 20 is provided in one battery pack 100, and the information collection member 20 is installed above a plurality of battery rows 10, and the information collection member 20 is electrically connected to a plurality of first electrical connection members 30 on the battery rows 10, and further connected to the electrical connection parts of the battery cells 11 by the first electrical connection members 30, thereby enabling the collection of information from the plurality of battery cells 11 on the battery rows 10, for example, temperature or voltage, and a connector 22 may be connected to the end of the information collection member 20, so that the signal collected by the information collection member 20 can be output via the connector 22, and further enabling monitoring of the state of the battery cells 11.

[0058] As shown in Figure 5, by installing one information gathering member 20 in multiple battery rows 10 of a single battery pack 100, one information gathering member 20 can be used to accommodate two or more battery rows 10. In other words, multiple battery rows 10 may share one information gathering member 20. Compared to having one information gathering member 20 per battery row 10, this effectively reduces the number of information gathering members 20 in the battery 1000, lowers the cost of the information gathering members 20, and further reduces the manufacturing cost of the battery 1000.

[0059] In the above embodiment, multiple battery cells 11 within each battery pack 100 are connected to an information collection member 20 by a first electrical connection member 30, facilitating connection sampling for the multiple battery cells 11 and acquiring information about each battery cell 11. As a result, multiple battery rows 10 within each battery pack 100 can share a single information collection member 20, effectively reducing the number of information collection members 20 within the battery 1000, thereby lowering the manufacturing cost of the battery 1000 and improving the market competitiveness of the product.

[0060] As shown in Figures 5-12, in some embodiments, in each battery pack 100, the information gathering member 20 corresponds to the central position of the multiple battery rows 10 in the second direction F2.

[0061] As shown in Figures 5 and 6, the multiple battery rows 10 of a single battery pack 100 are arranged along the left-right direction, and in the left-right direction, the information gathering member 20 is located in the center of the multiple battery rows 10, where the center may be in the middle of the multiple battery rows 10 or in 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, and the information gathering member 20 may be located above the two battery rows 10, with a part of the information gathering member 20 corresponding to one battery row 10 and the other part of the information gathering member 20 corresponding to the other battery row 10, and the information gathering member 20 may be located above one battery row 10 and adjacent to the other battery row 10.

[0062] By adopting the above arrangement structure, the connection between the information gathering member 20 and the multiple first electrical connection members 30 can be facilitated. The information gathering member 20 is positioned in the center, eliminating the need for bending or other processes to the information gathering member 20. This reduces the length of the information gathering member 20 as much as possible, thereby lowering the manufacturing cost of the information gathering member 20.

[0063] As shown in Figures 6-12, in some embodiments, the information gathering member 20 extends along a first direction F1.

[0064] As shown in Figures 6-12, the information gathering member 20 extends along the front-to-back direction, and the multiple battery cells 11 are arranged along the front-to-back direction. As a result, the extension direction of the information gathering member 20 is the same as the arrangement direction of the battery cells 11. Furthermore, this facilitates cooperation between the information gathering member 20 and the first electrical connection member 30 on the multiple battery cells 11, improving the convenience of connection. At the same time, the information gathering member 20 may be positioned in the center of the multiple battery rows 10. There is no need to perform bending or other processing on the information gathering member 20, and the length of the information gathering member 20 can be reduced as much as possible. The length of the information gathering member 20 may be approximately the same as the total thickness of the multiple battery cells 11, thereby reducing the manufacturing cost of the information gathering member 20.

[0065] In the above proposed technology, by adopting the above arrangement structure, the connection between the information gathering member 20 and the multiple first electrical connection members 30 is facilitated, improving the convenience of connection, and at the same time, the length dimension of the information gathering member 20 can be reduced as much as possible, thereby reducing the manufacturing cost of the information gathering member 20.

[0066] As shown in Figures 3-4 and 6-12, in some embodiments, the electrical connection includes a first electrical connection 111 and a second electrical connection 112, the first electrical connection 111 and the second electrical connection 112 having opposite polarities, and the first electrical connection 111 and the second electrical connection 112 are located on the same side of the battery cell 11.

[0067] As shown in Figures 6-12, the battery cell 11 includes a first electrical connection part 111 and a second electrical connection part 112, which have opposite polarities, that is, one is the positive terminal and the other is the negative terminal. At the same time, the first electrical connection part 111 and the second electrical connection part 112 are located on the same side of the battery cell 11, thereby facilitating the connection of the first electrical connection member 30 to connect the two connection parts with different polarities of two adjacent battery cells 11. The first electrical connection member 30 may be provided on one side of the battery cell 11 where the two electrical connection parts are provided, and the information gathering member 20 may be provided on the same side, further improving the convenience of connection.

[0068] In the following embodiment, the first electrical connection part 111 is described as the positive electrode connection part, and the second electrical connection part 112 is described as the negative electrode connection part.

[0069] As shown in Figures 6-8, in some embodiments, in each battery row 10, a first electrical connection portion 111 of one battery cell 11 and a second electrical connection portion 112 of an adjacent battery cell 11 are connected by a first electrical connection member 30.

[0070] As shown in Figures 6-8, in each battery row 10, the first electrical connection part 111 of one battery cell 11 and the second electrical connection part 112 of an adjacent battery cell 11 are connected by a first electrical connection member 30, realizing a series connection of each battery cell 11 in the battery row. That is, one first electrical connection member 30 connects two battery cells 11, thereby enabling the transmission of current and simultaneously accumulating the voltage within the battery row 10 to reach the required output voltage.

[0071] As shown in Figure 6, in some embodiments, in each battery row 10, the first electrical connection portion 111 of one battery cell 11 corresponds to the position of the second electrical connection portion 112 of the adjacent battery cell 11, and the two electrical connections are connected by a first electrical connection member 30, the first electrical connection member 30 extending along a first direction F1.

[0072] As shown in Figure 6, in each battery row 10, multiple battery cells 11 are arranged along the front-to-back direction. The first electrical connection portion 111 of one battery cell 11 corresponds to the position of the second electrical connection portion 112 of an adjacent battery cell 11. Taking the first battery cell 11 at the front as an example, its first electrical connection portion 111 is located to the left of the second electrical connection portion 112, and the rear of its first electrical connection portion 111 is the second electrical connection portion 112 of another battery cell 11. Thus, the first electrical connection portion 111 at the front and the second electrical connection portion 112 at the rear are connected by a first electrical connection member 30, enabling the transmission of current between the battery cells 11. The first electrical connection member 30 extends along the front-to-back direction, facilitating cooperation between the first electrical connection member 30 and the two connection portions. This shortens the length of the first electrical connection member 30, reducing manufacturing costs, while simultaneously ensuring a certain degree of stable current transmission and voltage transmission between the battery cells 11 in the battery row 10.

[0073] Here, the first electrical connection member 30 is connected to the information collection member 20, and the extension directions of the first electrical connection member 30 and the information collection member 20 may be the same, thereby reducing interference between the first electrical connection member 30 and the information collection member 20 and improving the convenience and reliability of the connection. Furthermore, the connection between the first electrical connection member 30 and the information collection member 20 may be a direct connection or an indirect connection, for example, connected by a conductive member 50, and the first electrical connection member 30 may extend support legs toward the information collection member 20, and the support legs may be connected to the information collection member 20, that is, the first electrical connection member 30 forms a T shape, thereby shortening the distance between the first electrical connection member 30 and the information collection member 20 and facilitating the connection between the two.

[0074] As shown in Figure 6, in some specific examples, each battery row 10 has two rows of first electrical connection members 30, where the first row of first electrical connection members 30 is spaced apart along the first direction and each of the first electrical connection members 30 in this row forms a straight line, the second row of first electrical connection members 30 is spaced apart along the first direction and each of the first electrical connection members 30 in this row forms a T-shape, and the second row is located on one side away from the information gathering members 20 of the first row.

[0075] In some selective examples, the first electrical connection member 30 in the first row may be connected to the information collection member 20 using the same conductive member 50, and the first electrical connection member 30 in the second row may be connected to the information collection member 20 using the same conductive member 50. That is, the conductive member 50 connecting the first electrical connection member 30 in the first row to the information collection member 20 may be a structural member of uniform dimensions, and the conductive member 50 connecting the first electrical connection member 30 in the second row to the information collection member 20 may be a structural member of uniform dimensions. This reduces manufacturing costs and simultaneously facilitates the connection of the conductive member 50 to each first electrical connection member 30, improving assembly efficiency.

[0076] As shown in Figures 7-8, 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 the adjacent battery cell 11 are positioned offset in the first direction F1, and the two electrical connections are connected by a first electrical connection member 30, the extending direction of the first electrical connection member 30 is inclined with respect to the first direction F1 and the second direction F2.

[0077] As shown in Figures 7 and 8, in each battery row 10, multiple battery cells 11 are arranged along the front-to-back direction, and the first electrical connection portion 111 of each battery cell 11 is located on the same side (same side in the left-to-right direction) as its second electrical connection portion 112. The arrangement of the two electrical connection portions of each battery cell 11 is the same, so that the positions of the electrical connection portions of the same polarity of two adjacent battery cells 11 are 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 positioned offset from each other.

[0078] Taking the first battery cell 11 on the front side of Figure 7 as an example, its first electrical connection portion 111 is located to the left of the second electrical connection portion 112, the rear of which 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 to the right of this first electrical connection portion 111, the front first electrical connection portion 111 and the rear second electrical connection portion 112 are connected by a first electrical connection member 30, the first electrical connection member 30 extends gradually from front to rear and inclined to the right, This enables the transmission of current between the two battery cells 11. The first electrical connecting member 30 may be in a straight line shape, thereby simplifying the structure of the first electrical connecting member 30 and facilitating its manufacturing and molding. In this battery array 10, the extension direction of each first electrical connecting member 30 is the same, and the multiple first electrical connecting members 30 are arranged at intervals along the front-to-back direction, thereby reducing the probability of the first electrical connecting member 30 interfering with other members and facilitating the connection between the first electrical connecting member 30 and the electrical connection part.

[0079] In some selective examples, the first electrical connection member 30 may be connected to the information gathering member 20 using the same conductive member 50, that is, the conductive member 50 may be a structural member of uniform dimensions, thereby reducing manufacturing costs and simultaneously facilitating the connection between the conductive member 50 and each first electrical connection member 30, thereby improving assembly efficiency. Selectively, the extension direction of each conductive member 50 is inclined with respect to the first direction F1 and the second direction F2. Selectively, the extension direction of the conductive member 50 is perpendicular to the extension direction of the first electrical connection member 30.

[0080] 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 positions of the first electrical connection portions 111 of the battery cells 11 in each battery combination 103 correspond, the positions of the second electrical connection portions 112 of the battery cells 11 in each battery combination 103 correspond, and the first electrical connection portion 111 of one battery combination 103 and the second electrical connection portion 112 of one adjacent battery combination 103 are connected by a first electrical connection member 30.

[0081] As shown in Figures 9-11, in each battery row 10, two adjacent battery cells 11 form one battery combination 103, and the first electrical connection 111 of two adjacent battery cells 11 and the second electrical connection 112 of other adjacent battery cells 11 are connected by a first electrical connection member 30. That is, one first electrical connection member 30 connects the corresponding electrical connection between four adjacent battery cells 11, enabling parallel connection of two adjacent battery cells 11 to realize current transmission, allowing the capacities of the battery cells 11 to be superimposed, and simultaneously connecting two sets of adjacent battery cells 11 in series, superimposing the voltages within the battery row 10 to reach the required output voltage.

[0082] Of course, three adjacent battery cells 11 may form one battery combination 103, or more battery cells 11 may form one battery combination 103.

[0083] As shown in Figure 9, in some embodiments, in each battery row 10, the first electrical connection portion 111 of one battery combination 103 corresponds to the position of the second electrical connection portion 112 of an adjacent battery combination 103 and is connected by a first electrical connection member 30, the first electrical connection member 30 extending along a first direction F1.

[0084] As shown in Figure 9, in each battery row 10, two adjacent battery cells 11 form one battery combination 103, the positions of the first electrical connection portions 111 of the two battery cells 11 within each battery combination 103 correspond, the first electrical connection portion 111 of each battery combination 103 corresponds to the position of the second electrical connection portion 112 of the adjacent battery combination 103, and are connected by the first electrical connection member 30. Taking the four battery cells 11 at the front as an example, the two front battery cells 11 form the first battery combination 103, and its first electrical connection portion 111 is located to the left of the second electrical connection portion 112, and the two rear battery cells 11 form the second battery combination 103 The first electrical connection portion 111 is located to the right of the second electrical connection portion 112, thereby connecting the two second electrical connection portions 112 of the first battery combination 103 and the two first electrical connection portions 111 of the second battery combination 103 by the first electrical connection member 30, enabling the transmission of current between the battery cells 11. The first electrical connection member 30 extends along the front-to-back direction, facilitating cooperation between the first electrical connection member 30 and the four electrical connection portions, thereby reducing the number of first electrical connection members 30 and lowering manufacturing costs, while simultaneously ensuring a certain degree of stable current transmission and voltage transmission between the battery cells 11 in the battery array 10.

[0085] Here, the first electrical connection member 30 is connected to the information collection member 20, and the extension directions of the first electrical connection member 30 and the information collection member 20 may be the same, thereby reducing interference between the first electrical connection member 30 and the information collection member 20 and improving the convenience and reliability of the connection. Furthermore, the connection between the first electrical connection member 30 and the information collection member 20 may be a direct connection or an indirect connection, for example, connected by a conductive member 50, and the first electrical connection member 30 may extend support legs toward the information collection member 20, and the support legs may be connected to the information collection member 20, that is, the first electrical connection member 30 forms a T shape, thereby shortening the distance between the first electrical connection member 30 and the information collection member 20 and facilitating the connection between the two.

[0086] As shown in Figure 9, in some specific examples, each battery row 10 has two rows of first electrical connection members 30, where the first row of first electrical connection members 30 is spaced apart along the first direction and each of the first electrical connection members 30 in this row forms a straight line, the second row of first electrical connection members 30 is spaced apart along the first direction and each of the first electrical connection members 30 in this row forms a T-shape, and the second row is located on one side away from the information gathering members 20 of the first row. In some selective examples, the first electrical connection member 30 in the first row may be connected to the information collection member 20 using the same conductive member 50, and the first electrical connection member 30 in the second row may be connected to the information collection member 20 using the same conductive member 50. That is, the conductive member 50 connecting the first electrical connection member 30 in the first row to the information collection member 20 may be a structural member of uniform dimensions, and the conductive member 50 connecting the first electrical connection member 30 in the second row to the information collection member 20 may be a structural member of uniform dimensions. This reduces manufacturing costs and simultaneously facilitates the connection of the conductive member 50 to each first electrical connection member 30, improving assembly efficiency.

[0087] As shown in Figures 10 and 11, in some examples, in each battery row 10, the first electrical connection 111 of one battery combination 103 and the second electrical connection 112 of an adjacent battery combination 103 are positioned offset in a first direction F1 and connected by a first electrical connection member 30, the first electrical connection member 30 being bent.

[0088] As shown in Figures 10 and 11, two adjacent battery cells 11 form a battery combination 103, the positions of the first electrical connections 111 of the two battery cells 11 in each battery combination 103 correspond, the positions of the second electrical connections 112 of the two battery cells 11 in each battery combination 103 correspond, the alignment direction of the two electrical connections in the first direction F1 of each battery combination 103 is the same, the first electrical connections 111 are located on the same side as the second electrical connections 112, and thus the first electrical connections 111 of one battery combination 103 are positioned offset from the second electrical connections 112 of the adjacent battery combination 103.

[0089] As shown in Figures 10 and 11, in each battery row 10, multiple battery cells 11 are arranged along the front-to-back direction, and the first electrical connection portion 111 of each battery cell 11 is located on the same side (same side in the left-to-right direction) as its second electrical connection portion 112. The arrangement of the two electrical connection portions of each battery cell 11 is the same, so that the positions of the electrical connection portions of the same polarity of two adjacent battery cells 11 are 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 positioned offset from each other.

[0090] Taking the first battery cell 11 at the front in Figure 10 as an example, its first electrical connection part 111 is located to the right of the second electrical connection part 112, the rear of which is the first electrical connection part 111 of another battery cell 11, and the second electrical connection part 112 of the other battery cell 11 is located to the left of this first electrical connection part 111. The two second electrical connection parts 112 at the front and the two first electrical connection parts 111 at the rear are connected by the first electrical connection member 30, thereby enabling the transmission of current between the four battery cells 11.

[0091] Here, the first electrical connection member 30 is bent, for example, in a Z shape, which facilitates the connection between the first electrical connection member 30 and the electrical connection parts of the four battery cells 11, thereby enabling the transmission of current and the series or parallel connection of the battery cells.

[0092] In a single battery row 10, the extension direction of each first electrical connection member 30 is the same, and the multiple first electrical connection members 30 are arranged at intervals along the front-to-back direction, thereby reducing the probability of the first electrical connection members 30 interfering with other members and facilitating the connection between the first electrical connection members 30 and the electrical connection part.

[0093] As shown in Figures 10 and 11, in some embodiments, the first electrical connection member 30 includes a first connection segment 31, a second connection segment 32, and a third connection segment 33, wherein the first connection segment 31 connects the first electrical connection portion 111 of two adjacent battery cells 11, and the third connection segment 33 connects the second electrical connection portion 112 of two other adjacent battery cells 11, and the first connection segment 31 and the third connection segment 33 extend along a first direction F1, the second connection segment 32 is connected between the first connection segment 31 and the third connection segment 33, and the extension direction of the second connection segment 32 is inclined with respect to the first direction F1 and the second direction F2, thereby enabling the first electrical connection member 30 to connect the first electrical connection portion 111 of two adjacent battery cells 11 and the second electrical connection portion 112 of two other adjacent battery cells 11, while simultaneously reducing the dimensions of the first electrical connection member 30 to some extent, optimizing the arrangement of the first electrical connection member 30, and meeting different design requirements.

[0094] In some selective examples, the first connection segment 31 or the third connection segment 33 of the first electrical connection member 30 may be connected to the information gathering member 20 using the same conductive member 50, that is, the conductive member 50 may be a structural member of uniform dimensions, thereby reducing manufacturing costs and at the same time facilitating the connection between the conductive member 50 and each of the first electrical connection members 30, thereby improving assembly efficiency.

[0095] As shown in Figures 6-7 and 9-10, in some embodiments, in two adjacent battery rows 10, the first electrical connection portion 111 of a 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 the other end of the adjacent battery row 10 by a second electrical connection member 40.

[0096] second Electric The connecting member 40 may be flat or substantially flat, and the second Electric The material of the connecting member 40 may include aluminum, copper, etc. Electric The connecting member 40 may be straight or U-shaped.

[0097] By installing the second electrical connection member 40, an electrical connection is made between the battery row 10 and adjacent battery rows 10, thereby enabling the integration of multiple battery rows 10 into a single unit, providing a larger electrical energy storage capacity or improving output power.

[0098] In some examples, the orientation of the first electrical connection portion 111 and the second electrical connection portion 112 of each battery cell 11 is the same. As shown in Figures 6-7 and 9-10, the battery 1000 has two battery rows 10, which are arranged along the left-right direction. The orientation of the electrical connection portions of the battery cells 11 in the left battery row 10 and the right battery row 11 is the same; that is, the first electrical connection portion 111 is located on the same side as the second electrical connection portion 112. For example, the battery cell 11 shown at the front of Figure 6 is located to the left of the second electrical connection portion 112 in the left battery row 10. The first electrical connection portion 111 of the battery cell 11 in the right-hand battery row 10 is similarly located to the left of the second electrical connection portion 112, so that the second electrical connection portion 112 of the battery cell 11 in the left-hand battery row 10 is adjacent to the first electrical connection portion 111 of the battery cell 11 in the right-hand battery row 10, and the second electrical connection member 40 extends along the left-right direction, that is, it can connect the two electrical connection portions, making the connection easy, thereby realizing an electrical connection between battery row 10 and adjacent battery row 10, thereby enabling the integration of multiple battery rows 10 to provide a larger electrical energy storage capacity or improve output power.

[0099] As shown in Figure 9, in some examples, the second electrical connection member 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, thereby achieving 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 other adjacent battery cells 11 are connected by the first electrical connection member 30, so that each electrical connection member connects four battery cells 11 simultaneously.

[0100] As shown in Figures 7 and 10, in some examples, the battery cell 11 has a pressure relief section 113, and the pressure relief section 113 may be located on the same side of the two electrical connection sections of the battery cell 11, and the arrangement direction of the electrical connection sections of two adjacent battery rows 10 may be the same, and the partial pressure relief section 113 is located between the electrical connection sections of the two battery rows 10, thereby allowing the second electrical connection member 40 to be designed in a bent shape, and the second electrical connection member 40 and the pressure relief section 113 are positioned offset from each other, so that the second electrical connection member 40 has a shielding effect on the pressure relief section 113 and prevents it from affecting the discharge of gas during thermal runaway.

[0101] As shown in Figures 8 and 11, in some embodiments, the orientation of the first electrical connection portion 111 and the second electrical connection portion 112 of the battery cell 11 is opposite in two adjacent battery rows 10.

[0102] As shown in Figures 8 and 11, the battery 1000 has two battery rows 10, which are arranged along the left-right direction. The arrangement direction of the electrical connections of the battery cells 11 in the left battery row 10 and the right battery row 10 is opposite. The first electrical connection 111 of the battery cell 11 in the left battery row 10 is located to the left of the second electrical connection 112, and the first electrical connection 111 of the battery cell 11 in the right battery row 10 is located to the right of the second electrical connection 112. The second electrical connection 112 of the end battery cell 11 in the left battery row 10 and the first electrical connection 111 of the middle end battery cell 11 in the right battery row 10 are connected by a second electrical connection member 40, thereby achieving electrical connection between the two adjacent battery rows 10.

[0103] As shown in Figures 8 and 11, in some embodiments, the battery cell 11 has a pressure relief section 113, which may be located on the same side of the two electrical connection sections of the battery cell 11, and all pressure relief sections 113 may be located between the electrical connection sections of the two battery rows 10, in which case the second electrical connection member 40 may be designed in a bent shape, and the second electrical connection member 40 and the pressure relief section 113 are positioned offset from each other so that the second electrical connection member 40 provides a shielding effect with respect to the pressure relief section 113, preventing it from affecting the discharge of gas during thermal runaway.

[0104] As shown in Figures 8 and 11, the second electrical connection member 40 includes a fourth connection segment 41, a fifth connection segment 42, and a sixth connection segment 43, wherein the sixth connection segment 43 is connected to the first electrical connection portion 111 of one or two battery cells 11, and the fourth connection segment 41 is connected to the second electrical connection portion 112 of one or two other battery cells 11, and the sixth connection segment 43 and the fourth connection segment 41 each extend along the first direction F1, and the fifth connection segment 42 is connected between the sixth connection segment 43 and the fourth connection segment 41, and the fifth connection segment 42 may also extend along the second direction F2, thereby enabling the second electrical connection member 40 to connect two battery cells 11 of two adjacent battery rows 10, while simultaneously reducing the dimensions of the second electrical connection member 40 to some extent, optimizing the arrangement of the second electrical connection member 40, and meeting different design requirements.

[0105] As shown in Figures 6 and 9, in some embodiments, the battery cell 11 has a pressure release section 113, the pressure release section 113 and the electrical connection section are located on the same side of the battery cell 11, and the pressure release section 113 is located between a first electrical connection section 111 and a second electrical connection section 112, and the projection of the pressure release section 113 in the plane where the first electrical connection member 30 is located is located outside the first electrical connection member 30.

[0106] The pressure relief section 113 is a component for releasing the pressure in the battery when the internal pressure of the battery cell 11 is too high. The pressure relief section 113 may be an explosion-proof valve or an explosion-proof sheet.

[0107] As shown in Figures 6 and 9, the pressure relief section 113 and the two electrical connection sections are both located on the upper side of the battery cell 11, and the pressure relief section 113 is located between the first electrical connection section 111 and the second electrical connection section 112. In the vertical direction, the pressure relief section 113 is positioned offset from the first electrical connection member 30. This allows high-pressure gas to be discharged through the pressure relief section 113 when thermal runaway occurs in the battery cell 11, preventing the first electrical connection member 30 from blocking the pressure relief at the pressure relief section 113 and affecting the discharge of high-pressure gas.

[0108] It should be explained that the information gathering member 20 generally employs a flexible material with relatively low structural strength. Even if the information gathering member 20 is located above the pressure relief section 113, and even if it shields some of the pressure relief valves 113, when thermal runaway occurs in the battery cell 11, the high-pressure gas can be discharged through the pressure relief section 113. At the same time, the high-pressure gas can penetrate the information gathering member 20, thereby ensuring to some extent the smooth discharge of the high-pressure gas.

[0109] In the above proposed technology, the first electrical connection member 30 and the pressure release section 113 are positioned with a staggered shape, thereby enabling the battery cell 1 1 This improves reliability and stability and helps to mitigate safety risks to a certain extent.

[0110] As shown in Figures 7-8 and 10-11, in some embodiments, the battery cell 11 has a pressure release section 113, the pressure release section 113 and the electrical connection section are located on the same side of the battery cell 11, and the pressure release section 113 is located on the same side in the second direction F2 of the first electrical connection section 111 and the second electrical connection section 112, and the projection of the pressure release section 113 in the plane where the first electrical connection member 30 is located is located outside the first electrical connection member 30.

[0111] As shown in Figures 7-8 and 10-11, the pressure relief section 113 and the two electrical connection sections are both located on the upper side of the battery cell 11. The pressure relief section 113 is located on the same side (right side as shown in Figure 7) as the first electrical connection section 111 and the second electrical connection section 112. In the vertical direction, the pressure relief section 113 is offset from the first electrical connection member 30. This allows high-pressure gas to be discharged through the pressure relief section 113 when thermal runaway occurs in the battery cell 11, preventing the first electrical connection member 30 from blocking the pressure relief at the pressure relief section 113 and affecting the discharge of high-pressure gas.

[0112] It should be explained that the information gathering member 20 generally employs a flexible material with relatively low structural strength. Even if the information gathering member 20 is located above the pressure relief section 113, and even if it shields some of the pressure relief valves 113, when thermal runaway occurs in the battery cell 11, the high-pressure gas can be discharged through the pressure relief section 113. At the same time, the high-pressure gas can penetrate the information gathering member 20, thereby ensuring to some extent the smooth discharge of the high-pressure gas.

[0113] In the above proposed technology, the first electrical connection member 30 and the pressure release section 113 are positioned with a staggered shape, thereby enabling the battery cell 1 1 This improves reliability and stability and helps to mitigate safety risks to a certain extent.

[0114] In some embodiments, the battery cell 11 has a pressure release section 113, and the pressure release section 113 and the electrical connection section are located on different sides of the battery cell 11.

[0115] The battery cell 11 has a first electrical connection section 111 and a second electrical connection section 112 on its upper side, and a pressure release section 113 is located on its lower side. This positions the pressure release section 113 and the electrical connection sections on different sides of the battery cell 11. In this configuration, the first electrical connection member 30 and the second electrical connection member 40, which cooperate with the electrical connection sections, do not interfere with the pressure release section 113, allowing the high-pressure gas inside the battery cell 11 to be discharged through the pressure release section 113. This improves the effectiveness of the exhaust from the pressure release section 113 and enhances the reliability and stability of the battery cell. Of course, the pressure release section 113 may be located on the left or right side of the battery cell 11, and the electrical connection sections may be located on the upper or lower side of the battery cell 11, positioning the pressure release section 113 and the electrical connection sections on different sides of the battery cell 11.

[0117] As shown in Figures 6-12, the first battery row 101 is located to the left of the second battery row 102, and the first battery row 101 includes a plurality of first battery cells, two adjacent first battery cells are connected by a first electrical connecting member 30, and the second battery row 102 includes a plurality of second battery cells, two adjacent second battery cells are connected by a first electrical connecting member 30, and as can be understood, as shown in Figures 6-8 and 12, the first electrical connecting member 30 may also be connected to two adjacent battery cells, in this case the second The electrical connection member 40 is connected to one first battery cell and one second battery cell, thereby connecting multiple battery cells 11 of the first battery row 101 and the second battery row 102 in series. Alternatively, as shown in Figures 9-11, the first electrical connection member 30 may be connected to four adjacent battery cells, in which case the second electrical connection member 40 is connected to two first battery cells and two second battery cells, thereby connecting multiple battery cells 11 of the first battery row 101 and the second battery row 102 in parallel and series.

[0118] Multiple first electrical connection members 30 are connected to the information collection member 20, and second electrical connection members 40 are connected to the information collection member 20, thereby enabling the collection of information from multiple battery cells 11 in the first battery array 101 and the second battery array 102, for example, by collecting temperature or voltage, and further enabling monitoring of the state of the battery cells 11.

[0119] Of course, battery pack 10 0 The battery may also have a third battery row, a fourth battery row, and so on. By adjusting the positions of the electrical connection part and the pressure release part 113 of the battery cell 11, the distance between the first electrical connection part 111 and the second electrical connection part 112 can be adjusted, and one information gathering member 20 may be used for multiple battery rows. This effectively reduces the number of information gathering members 20 in the battery 1000 and lowers manufacturing costs.

[0120] As shown in Figure 12, in some embodiments, the information gathering member 20 and the first electrical connection member 30 are directly connected.

[0121] As shown in Figure 12, the information gathering member 20 is directly connected to the first electrical connection member 30, thereby reducing the number of parts, lowering manufacturing costs, and simultaneously reducing assembly operations and improving assembly efficiency. Of course, the second electrical connection member 40 may also be directly connected to the information gathering member 20.

[0122] As shown in Figure 12, in some embodiments, one of the information gathering member 20 and the first electrical connection member 30 has a support leg 21, and the other of the information gathering member 20 and the first electrical connection member 30 is connected to the support leg 21.

[0123] As shown in Figure 12, the information gathering member 20 has support legs 21, which can extend to the first electrical connection member 30. By overlapping the portion of the support legs 21 with the portion of the first electrical connection member 30 and further connecting the support legs 21 to the first electrical connection member 30, the information gathering member 20 and the first electrical connection member 30 can be connected. By installing the support legs 21, the connection between the information gathering member 20 and the first electrical connection member 30 is facilitated, and manufacturing costs are reduced without excessively increasing the dimensions of the information gathering member 20 or the first electrical connection member 30.

[0124] Of course, the first electrical connection member 30 may have support legs extending toward the information acquisition member 20, and the information acquisition member 20 may be connected to the support legs of the first electrical connection member 30, or the support legs 21 of the information acquisition member 20 may be connected to the support legs of the first electrical connection member 30.

[0125] Of course, in the embodiments shown in Figures 6-11, the information gathering member 20 and the first electrical connection member 30 may be directly connected, thereby eliminating the conductive member 50 shown in the figures and reducing manufacturing costs.

[0126] As shown in Figure 12, in some embodiments, the information acquisition member 20 and the first electrical connection member 30 are welded together. For example, the information acquisition member 20 has support legs 21, which are integrally molded with the information acquisition member 20, and the support legs 21 are welded to the first electrical connection member 30. By connecting the two by welding, a reliable connection between the information acquisition member 20 and the first electrical connection member 30 is achieved, and electrical signals can be transmitted at the same time. Connection is easy, and assembly efficiency is improved.

[0127] Furthermore, the information gathering member 20 may be directly connected to the second electrical connection member 40. For example, the information gathering member 20 may have support legs 21, which are welded to the second electrical connection member 40.

[0128] As shown in Figures 6-11, in some embodiments, each battery pack 100 further includes a conductive member 50, and the first electrical connection member 30 is connected to the information gathering member 20 by the conductive member 50.

[0129] As shown in Figures 6-11, the first electrical connection member 30 and the information collection member 20 are spaced apart and connected by a conductive member 50. One end of the conductive member 50 is connected to the first electrical connection member 30, and the other end is connected to the information collection member 20. The conductive member 50 may be a nickel sheet, which is a conductive material that can effectively transmit electric current and has good corrosion resistance. The conductive member 50 may be welded to the first electrical connection member 30 and the information collection member 20, respectively, making the connection easy and reliable. The second electrical connection member 40 may also be connected to the information collection member 20 by the conductive member 50.

[0130] In some embodiments, each battery pack 100 further includes a temperature collection module that contacts the battery cell 11 to collect the temperature of the battery cell 11.

[0131] Each battery pack 100 includes one or more temperature acquisition modules, which are devices for monitoring and recording the temperature of the battery cells. The temperature acquisition modules can monitor and control the temperature of the battery cells in real time, making it easy to timely detect abnormal temperature conditions and take appropriate measures, such as heat dissipation or threshold alarms, thereby ensuring the safety and performance of the battery cells 11.

[0132] Here, the temperature acquisition module makes contact with one or more battery cells 11 to acquire accurate temperature data and can also detect abnormal conditions such as overheating in a timely manner.

[0133] In some examples, the temperature collection module is integrated into the information collection member 20.

[0134] By integrating the temperature collection module into the information collection member 20, the temperature of the battery cell 11 can be easily measured and recorded, and the temperature data can be processed and analyzed together with other parameter data. As a result, the information collection member 20 not only has the function of collecting parameters of other battery cells, but also the function of collecting the temperature of the battery cell 11.

[0135] In some embodiments, the temperature collection module is integrated into the first electrical connection member 30.

[0136] By integrating the temperature collection module into the first electrical connection member 30, the temperature of the battery cell 11 can be easily measured, and the temperature data can be transmitted to a battery management system or other monitoring equipment for real-time monitoring and analysis. This enables real-time understanding of the temperature of the battery cell 11, as well as real-time response to and management of abnormal temperature conditions. As a result, the first electrical connection member 30 can transmit current and collect temperature, expanding the functionality of the first electrical connection member 30.

[0137] Furthermore, the temperature collection module may be integrated into the second electrical connection member 40, extending the functionality of the second electrical connection member 40. Of course, the temperature collection module may also be integrated into the conductive member 50.

[0138] In some embodiments, the information gathering member 20 is a Flexible Printed Circuit (FPC), which is a flexible printed circuit, and is a circuit board manufactured using a flexible substrate. It is flexible and plastic, and has relatively low rigidity. Therefore, even if the flexible circuit board is placed above the pressure relief section 113, when thermal runaway occurs in the battery cell 11, the high-pressure gas is discharged through the pressure relief section 113, and the flexible circuit board can be punctured. Furthermore, the gas is discharged to the outside of the battery 1000 through the exhaust passage, allowing for rapid discharge of the high-pressure gas and reducing the risk of gas condensation. Thus, by using a flexible circuit board, situations where high-pressure gas cannot be discharged can be avoided to some extent, reducing safety risks.

[0139] The power consumption device 2000 according to the second embodiment of this application includes the battery 1000 according to the first embodiment of this application, the battery 1000 being used to provide electrical energy to the power consumption device 2000. This makes it advantageous to improve the safety and reliability of the power consumption device 2000 by using the aforementioned battery 1000.

[0140] Selectively, as shown in Figure 1, when the battery 1000 is used in a vehicle, the battery 1000 may be installed at the bottom, front, or rear of the vehicle. The battery 1000 may be used to power the vehicle; for example, the battery 1000 may be used as the operating power source for the vehicle. The vehicle may further include a controller and a motor, the controller being used to control the battery 1000 to power the motor and to meet the operating power consumption requirements for, for example, starting the vehicle, navigation, and driving.

[0141] The following describes a specific embodiment of the battery 1000 and a vehicle having the same, with accompanying drawings.

[0143] The first battery array 101 includes a plurality of first battery cells, each having a first electrical connection portion 111 and a second electrical connection portion 112 with opposite polarities, and a pressure relief portion 113 between the first electrical connection portion 111 and the second electrical connection portion 112. Here, the first electrical connection portion 111 of one battery cell 11 corresponds to the position of the second electrical connection portion 112 of an adjacent battery cell 11, i.e., the positive and negative poles are arranged alternately, and the two electrical connection portions with opposite polarities of two battery cells 11 are connected by a first electrical connection member 30.

[0144] The second battery array 102 includes a plurality of second battery cells, each having a first electrical connection 111 and a second electrical connection 112 with opposite polarity, and a pressure relief section 113 between the first electrical connection 111 and the second electrical connection 112. Here, the first electrical connection 111 of one battery cell 11 corresponds to the position of the second electrical connection 112 of an adjacent battery cell 11, i.e., the positive and negative poles are arranged alternately. The two electrical connection sections with opposite polarity of two battery cells 11 are connected by a first electrical connection member 30. Here, the arrangement direction of the electrical connection sections of the second battery array 102 and the first battery array 101 is the same.

[0145] The first electrical connection part 111 of the first battery cell and the second electrical connection part 112 of the second battery cell are connected by the second electrical connection member 40, thereby achieving electrical connection within each battery pack 100.

[0146] The information gathering member 20 is a flexible circuit board, positioned above the first battery row 101 and the second battery row 102, and located in the center of the entire battery pack 100 in the horizontal direction. The information gathering member 20 is connected to the first electrical connection member 30 and the second electrical connection member 40 by a conductive member 50, so that two rows of battery cells 11 within the same battery row 10 share one information gathering member 20, and a temperature detection module is integrated into the information gathering member 20.

[0147] In the above embodiment, the number of information gathering members 20 in the battery 1000 can be effectively reduced, which helps to lower the manufacturing cost of the battery 1000 and improves the market competitiveness of the product.
