[0062] With the vigorous development of new energy industry, the capacity of the battery device is getting larger and larger, and the performance requirements of the battery device are getting higher and higher. The battery device usually includes one or more battery monomers, and the battery management assembly can be arranged in the battery device. The battery management assembly can monitor the state of the battery monomer during use of the battery device, and adaptively manage the battery monomer.

[0063] The battery device can also be provided with a data transmission assembly, which can transmit the working condition data of the battery device collected by the battery management assembly to the server, and also can convey the instructions issued by the server to the battery management assembly.

[0064] The battery device usually needs regular maintenance or repair during use. When designing the battery device, it is usually considered that the data transmission assembly and other components of the battery device can adopt the same maintenance or repair period. However, based on research, it is found that as the overall life of the battery device improves, the possibility of damage to the data transmission assembly will increase in the later stage of use of the battery device. Therefore, the data transmission assembly needs to be frequently repaired or even replaced in the later stage of use of the battery device. Moreover, research has also found that with the progress of science and technology, the communication technology of the data transmission assembly updates and iterates faster. Before the service life of the battery device is reached, the battery device may need to replace a new generation of data transmission assembly. Therefore, it may be necessary to regularly repair or replace the data transmission assembly alone. However, when the data transmission assembly of the battery device is repaired or replaced alone, the convenience is poor, resulting in an increase in the repair and maintenance cost of the battery device. Moreover, the data transmission assembly usually needs to be replaced as a whole when it is replaced, which is costly.

[0065] Based on the above research, the battery device provided in the application is provided, the data transmission component of the data transmission assembly of the battery device is provided in a split manner, and the data transmission component is externally provided. In this way, the data transmission component can be independently maintained or replaced without affecting the various components inside the box. When the data transmission component needs to be maintained or replaced, the detection and replacement of the corresponding components can be directly performed outside the box, thereby saving the opening time and maintenance and repair costs, reducing the influence of opening the box on the performance of the battery device, improving the convenience of maintenance or repair of the battery device, and the data transmission component and the data processing component can be independently replaced, thereby reducing the cost.

[0089] As an example, the positive electrode active material can include at least one of a lithium-containing phosphate, a lithium transition metal oxide, and a modified compound of each thereof.

[0090] In some embodiments, the negative electrode can be a negative electrode sheet, which can include a negative electrode current collector.

[0091] As an example, the negative electrode current collector can employ a metal foil, a conductive polymer material, a carbon material, or a composite current collector. For example, as the metal foil, a pure metal, an alloy, a surface-treated metal, including but not limited to stainless steel, copper, aluminum, nickel, titanium, or silver, etc. can be employed. The composite current collector can include a polymer material base layer and a metal layer. The composite current collector can be formed by forming a metal material (copper, copper alloy, nickel, nickel alloy, titanium, titanium alloy, silver, and silver alloy, etc.) on a polymer material base material (such as a base material of polypropylene, polyethylene terephthalate, polybutylene terephthalate, polystyrene, polyethylene, etc.).

[0092] As an example, the negative electrode sheet can include a negative electrode current collector and a negative electrode active material disposed on at least one surface of the negative electrode current collector.

[0093] As an example, the negative electrode current collector has two surfaces opposite in the thickness direction thereof, and the negative electrode active material is disposed on either one or both of the two opposite surfaces of the negative electrode current collector.

[0094] As an example, the negative electrode active material can employ a negative electrode active material for a battery cell known in the art.

[0095] The separator is a separator film. The kind of the separator film is not particularly limited in the present application, and any known porous structure separator film having good chemical stability and mechanical stability can be used.

[0096] As Figure 4 shown, Figure 4This is a simplified schematic diagram illustrating the electrical control connections of an electrical device and battery unit according to some embodiments of this application. The battery unit 10 may further include a battery management component 200, also known as a battery management unit, for monitoring and managing individual battery cells 101. The battery management component 200 can monitor battery data such as current, voltage, power, or temperature of the individual battery cells 101. For example, it can control the charging and discharging current and voltage of the individual battery cells 101. The battery management component 200 includes modules such as an auxiliary battery management unit (SBMU) and a fusion switch.

[0097] Optionally, the battery device 10 also includes a central control module 41, which can be used to monitor and manage the battery device 10 of the electrical device. The central control module 41 can monitor information such as current, voltage, power, state of charge, or temperature of the battery device 10. For example, it can control the charging and discharging current and voltage of the battery device 10. As an example, the central control module 41 includes modules such as an insulation monitoring module (IMM) and a master battery management unit (MBMU).

[0098] like Figure 4 As shown, the battery management component 200 of the battery device 10 can communicate with the control unit of the electrical equipment (e.g., the controller 20 of the vehicle 1000) via the main control module 41. Optionally, the control unit of the electrical equipment (e.g., the controller 20 of the vehicle 1000) can be electrically connected to the main control module 41 via a wiring harness (refer to the third wiring harness 50), and the main control module 41 can be connected to the battery management component 200 of the battery device 10 via a wiring harness (refer to the third wiring harness 50). Specifically, the wiring harness (refer to the third wiring harness 50) can be a CAN line, which stands for Controller Area Network (CAN) bus. CAN is a multi-master serial communication network mainly used for distributed control and real-time control. It uses communication data blocks for encoding, replacing the traditional station address encoding, thus theoretically allowing an unlimited number of nodes within the network. In the vehicle 1000, the main control module 41 can be located within the vehicle-side high-voltage box 40.

[0099] In some embodiments, the battery device 10 may optionally include a data transmission component 300, which serves as a data communication bridge between the battery device 10 and the server, enabling communication between the battery management component 200 and the server. The server may be a cloud server 1, or a server for an electrical device, such as a vehicle-side controller 20; the server may also be a server at a service station or a host computer for the battery device 10.

[0100] For example, the server can be a cloud server 1, which can be, but is not limited to, a remote control center for the battery device 10, capable of remotely monitoring and managing the status of the battery device. The data transmission component 300 is a component used to implement remote data transmission. For example, the data transmission component 300 can be an RDB transmission component (an RDB transmission component is a remote data transmission component, where R represents remote, D represents database, and B represents bridge or box). The functions of the data transmission component 300 include: transmitting data from the battery device 10 back to the cloud server 1; periodically transmitting data back to the cloud server 1 when the vehicle 1000 is powered down (power down refers to the start of the vehicle 1000's electrical system, including the power supply of low-voltage and high-voltage systems); controlling commands issued by the cloud server 1, which may include controlling the battery device 10; adjusting the data transmission period of the battery device 10 (transmission refers to the process of transmitting data back to the cloud server 1); and remotely upgrading the relevant software of the battery device 10, for example, upgrading the software of the battery management component 200 via OTA (Over-The-Air, a method for remotely updating device firmware or software through wireless communication technology). In some implementations, the data transmission component 300 may also have the function of locating the position information of the battery device 10.

[0101] The data transmission component 300 and the battery management component 200 can be connected wirelessly or via a wired connection. For example, the data transmission component 300 and the battery management component 200 can be connected via a wiring harness (refer to the second wiring harness 420). This wiring harness (refer to the second wiring harness 420) can be a data line that has both power supply and data transmission functions. Alternatively, the wiring harness can include a separately configured power supply wire 421 and a communication line 422 (e.g., a CAN line) for data transmission.

[0102] like Figures 2 to 4 and combined Figures 5 to 8 As shown, Figure 5 This is a schematic diagram illustrating the communication connection between the battery management component, the data transmission component, and the cloud server according to some embodiments of this application. Figure 6This is a schematic diagram of the assembly of a portion of the battery device housing and data transmission components according to some embodiments of this application, from one perspective. Figure 7 This application presents an assembly diagram of a portion of the battery device housing and data transmission components from another perspective, based on some embodiments thereof. Figure 8 This is a cross-sectional view of the assembly of the housing (first wall) and data transmission component of a battery device according to some embodiments of this application. An embodiment of this application provides a battery device 10 including a housing 13, a battery management component 200, at least one battery cell 101, and a data transmission component 300. At least one battery cell 101 is disposed within the housing 13. The battery management component 200 is disposed within the housing 13 and connected to the at least one battery cell 101. The battery management component 200 collects battery data from the at least one battery cell 101 and manages the battery cell 101 based on this battery data. The data transmission component 300 includes a separately disposed data transmission part 310 and a data processing part 320. The data transmission part 310 is communicatively connected to the battery management component 200 through the data processing part 320. The data processing part 320 receives the battery data and filters the battery data. The data transmission part 310 sends the filtered battery data to a server.

[0103] The communication connection involved in this embodiment refers to the communication established between connected devices through signal transmission and interaction, which can be either a wired communication connection or a wireless communication connection.

[0104] like Figure 6 and Figure 7 As shown, the housing 13 can be divided into an energy storage compartment 131 and a functional compartment 132. The energy storage compartment 131 is used to house individual battery cells 101, and the functional compartment 132 is used to house components such as the battery management assembly 200.

[0105] There can be one or more battery cells 101, and all battery cells 101 can be disposed inside the housing 13.

[0106] The data transmission component 300 is used to implement data transmission of the battery management component 200. It can receive and send relevant data of the battery management component 200 to the service, and it can also receive and send instructions sent by the server to the battery management component 200.

[0107] The data processing component 320 can be in wired communication with the battery device 10 (the battery management assembly 200) and the vehicle-side high-voltage box 40 through a wire harness (defined as a second wire harness 420 for ease of description) to receive and filter the battery data of the battery device 10 (the battery management assembly 200) and send the filtered data to the data transmission component 310. The second wire harness 420 and the data processing component 320 can be detachably connected or fixedly connected. The second wire harness 420 and the battery management assembly 200 can be fixedly connected or detachably connected through a connector.

[0108] For example, the server can be a cloud server 1, and the data transmission component 310 can be a wireless communication component that can be in wireless communication with the cloud server 1 and can be used to send data of the battery management assembly 200 to the cloud server 1 or send instructions of the cloud server 1 to the battery management assembly 200. By providing the data transmission component 310, the data, location information, etc. of the battery device 10 can be transmitted to the cloud server 1 in real time, which facilitates the cloud server 1 to manage and locate the assets of the battery device 10 and can be combined with big data to monitor the battery device 10 throughout its life cycle and improve the service life of the battery device 10.

[0109] Optionally, the data transmission component 310 can include a 4G communication component, a 3G (third generation mobile communication technology) communication component, and / or a 5G communication component.

[0110] The data processing component 320 and the data transmission component 310 are separately provided, which means that the data processing component 320 and the data transmission component 310 are independently provided in a mechanical relationship. The data processing component 320 and the data transmission component 310 can be separately provided at different positions. The data processing component 320 and the data transmission component 310 can each have an independent circuit board, that is, the circuit, chip, and other electrical devices of the data processing component 320 can be integrated on one circuit board, and the circuit, chip, and other electrical devices of the data transmission component 310 can be integrated on another circuit board.

[0111] Optionally, the data processing component 320 and the data transmission component 310 can be located at different positions in the box 13. Alternatively, the data processing component 320 and the data transmission component 310 can be located at different positions outside the box 13. Alternatively, one of the data processing component 320 and the data transmission component 310 can be located outside the box 13, and the other can be located inside the box 13.

[0112] For example, the data processing component 320 and the data transmission component 310 can be communicatively connected through a wire harness (for the convenience of description, the wire harness is defined as a first wire harness 400). Optionally, the first wire harness 400 and the data transmission component 310 can be detachably connected through a connector or the like, and optionally, the first wire harness 400 and the data processing component 320 can also be detachably connected through a connector or the like.

[0113] In the battery device of the embodiment, the data transmission component 300 can realize data transmission of the battery management component 200. By separately arranging the data transmission component 310 and the data processing component 320 of the data transmission component 300, the data transmission component 310 and the data processing component 320 can be individually repaired, maintained or replaced, which improves the operation convenience and reduces the repair or maintenance time and cost of the battery device 10.

[0114] According to some embodiments of the present application, optionally, as shown in Figures 2 to 8 The data transmission component 310 is arranged on the outer wall surface of the box 13, or the box 13 is provided with an assembly hole 134 which is in communication with the outside of the box 13, and the data transmission component 310 is at least partially arranged in the assembly hole 134, and the data transmission component 310 is arranged to be capable of being inserted into or detached from the assembly hole 134 from the outside of the box 13.

[0115] The outer wall surface of the box 13 refers to the wall surface of the box 13 exposed to the outside, i.e. the side of the wall of the box 13 away from the battery monomer 101. The data transmission component 310 is mounted on the outer wall surface of the box 13, which means that the data transmission component 310 is arranged exposed to the outside of the box 13.

[0116] In some embodiments, the data transmission component 310 can be arranged on the outer wall surface of any one wall of the box 13. For example, the data transmission component 310 can be arranged on the top surface of the top wall of the box 13, or on the top surface of the bottom wall of the box 13 or the outer surface of any one side wall.

[0117] The data transmission component 310 and the corresponding outer wall surface can be detachably connected or non-detachably connected. The detachable connection means that the two connected parts (in this embodiment, the data transmission component 310 and the corresponding outer wall surface of the box 13) can be disassembled and reassembled without the aid of destructive means. The detachable connection can be achieved by screwing, clamping, or other means. The non-detachable connection means that once the connection is completed, it is difficult or impossible to disassemble without damaging the components. The non-detachable connection can include welding, riveting, and bonding. It should be noted that when the data transmission component 310 and the outer wall surface of the box 13 are connected in a non-detachable manner, the data transmission component 310 can be disassembled by damaging the data transmission component 310 or the connecting component connecting the data transmission component 310 and the box 13, so as to reduce the damage to the box 13.

[0118] For example, the data transmission component 310 can be arranged on the surface of the outer wall surface of the box 13 and protrude from the outer wall surface of the box 13.

[0119] For example, the data transmission component 310 can be embedded in the outer wall surface of the box 13. Specifically, the outer wall surface of the box 13 can be provided with a groove, and the data transmission component 310 can be arranged in the groove and located entirely in the groove, or the data transmission component 310 can be mounted in the groove and partially protrude from the groove.

[0120] In some embodiments, the box 13 is provided with an assembly hole 134, the assembly hole 134 is in communication with the outer side of the box 13, and the data transmission component 310 is at least partially arranged in the assembly hole 134, and the data transmission component 310 is arranged to be capable of being inserted into or separated from the assembly hole 134 from the outer side of the box 13.

[0121] The assembly hole 134 can pass through the wall of the box 13.

[0122] Optionally, the data transmission component 310 can be entirely arranged in the assembly hole 134.

[0123] Optionally, the data transmission component 310 can also be partially arranged in the assembly hole 134, and other parts of the data transmission component 310 can be arranged on the outer side of the box 13 or in the box 13.

[0124] The data transmission component 310 is configured to be inserted into or detached from the assembly hole 134 from the outside of the box 13. This means that during the process of assembling the data transmission component 310 to the box 13, the data transmission component 310 can be inserted into the assembly hole 134 from the outside of the box 13 when the box 13 is in a closed state. Meanwhile, during the process of detaching the data transmission component 310 from the box 13, the data transmission component 310 can be detached from the assembly hole 134 towards the end of the box 13 outside the assembly hole 134 when the box 13 is in a closed state.

[0125] It should be noted that when the data transmission component 310 is at least partially arranged in the assembly hole 134, the data transmission component 310 and the box 13 can be detachably connected or non-detachably connected.

[0126] The battery device 10 of the present embodiment can directly detect and replace corresponding components outside the box 13 during the process of repairing or maintaining the data transmission component 310 by mounting the data transmission component 310 on the outer side of the box 13 or in the mounting hole 314 of the box 13. Compared with the mode in which the data transmission component 310 is arranged in the box 13 (in this mode, the top cover of the box 13 needs to be disassembled, and the opening cost is even higher than the body cost of the data transmission component 310), the opening time and the repair and maintenance cost are saved, the influence of opening on the performance of the battery device 10 is reduced, and the convenience of repairing or maintaining the battery device 10 is improved. In addition, by mounting the data transmission component 310 on the outer side of the box 13, the replaceability of the data transmission component 310 is improved. When the product of the battery device 10 is not suitable for the network of the current environment, for example, when the network is generally upgraded from 4G (the fourth generation mobile communication technology) to 5G (the fifth generation mobile communication technology), the data transmission component 310 can be directly replaced without opening the box 13. Moreover, the data transmission component 310 is arranged outside, which can reduce the electrical components in the box 13 and improve the available space in the box 13 of the battery device 10. The data transmission component 310 and the data processing component 320 can be replaced independently, thereby reducing the cost.

[0127] According to some embodiments of the present application, the data processing component 320 is arranged in the box 13. Figures 5 to 8

[0128] The data processing component 320 and the battery management assembly 200 can be arranged in the functional compartment 132. For example, the data processing component 320 and the battery management assembly 200 can be arranged separately and located at different positions of the functional compartment 132.

[0129] For example, the data processing component 320 is arranged in the functional compartment 132. Figure 6 ​and Figure 7 As shown in the figure, the data processing component 320 comprises an assembly shell and a data processing element arranged in the assembly shell, the data processing element comprises a circuit board and electrical devices arranged on the circuit board, and the assembly shell is mounted in the functional compartment 132 by a fixing member (such as a bolt). Alternatively, a mounting seat is arranged in the functional compartment 132, and the data processing component 320 is mounted in the mounting seat by a fixing member. The mounting seat can be a rod structure arranged in the functional compartment 132 and connected with the box body 13.

[0130] Compared with the data transmission component 310, the data processing component 320 has a lower replacement or maintenance frequency, so the data processing component 320 can be arranged in the box body 13. By embedding the data processing component 320 in the box body 13 of the battery device 10, the protection performance of the data transmission component 310 can be improved, and the rationality of the component arrangement of the battery device 10 can be improved.

[0131] According to some embodiments of the present application, the data transmission component 310 can be arranged in the box body 13 of the battery device 10, and the data transmission component 310 can be arranged in the functional compartment 132 of the box body 13. Figures 5 to 8 , and in combination with Figures 9 to 11 As shown in the figure, Figure 9 The assembly structure schematic diagram of the data transmission component 310, the positioning component 340 and the antenna 330 for some embodiments of the present application, Figure 10 The assembly structure schematic diagram of the data transmission component 310, the positioning component 340 and the antenna 330 for some embodiments of the present application, Figure 11 The assembly structure schematic diagram of the data transmission component 310, the positioning component 340 and the antenna 330 for some embodiments of the present application, the data transmission assembly 300 further comprises an antenna 330, the antenna 330 is electrically connected with the data transmission component 310, the antenna 330 is used to enhance the signal strength of the data transmission component 310, and the antenna 330 is arranged on the outside of the box body 13.

[0132] The antenna 330 can be used to enhance the signal, improve the stability of data transmission and the data transmission range. The antenna 330 can be a metal material.

[0133] The antenna 330 can comprise an antenna for enhancing the signal of the data transmission component 310, for example, a 4G antenna corresponding to a 4G communication component, a 3G antenna corresponding to a 3G communication component, and / or a 5G antenna corresponding to a 5G communication component, etc., which can enhance the signal strength of the cellular network.

[0134] When the data transmission assembly 300 is provided with the positioning component 340, the antenna 330 can further comprise a component for enhancing the positioning signal, for example, a GNSS antenna corresponding to a GNSS positioning module, which can enhance the GNSS satellite signal strength and search for Beidou satellite, etc.

[0135] For example, the data transmission component 310 and the antenna 330 can be separately configured, and the antenna 330 and the data transmission component 300 can be electrically connected via a wiring harness. The data transmission component 310 and the antenna 330 can be relatively independent and each can be fixed to the housing 13.

[0136] For example, the data transmission component 310 is disposed in the mounting hole 134, and the antenna 330 is mounted on the outer wall of the housing 13.

[0137] For example, such as Figures 6 to 11 As shown, the data transmission component 310 and the antenna 330 can also be integrated, and the antenna 330 and the data transmission component 300 are connected by a circuit or directly. For example, the data transmission component 310 and the antenna 330 can be integrated into the housing 311 and fixedly connected to the enclosure 13 through the housing 311.

[0138] In this embodiment, the battery device 10, by setting up an antenna 330, can improve the stability and range of data transmission. At the same time, the antenna 330 is located on the outside of the housing 13, which can reduce the signal shielding effect of the housing 13 on the antenna 330, and also facilitate the maintenance, repair or replacement of the antenna 330.

[0139] According to some embodiments of this application, optionally, such as Figures 6 to 11 As shown, the data transmission component 310 includes a housing 311 and a data transmission element 318. The housing 311 is connected to the enclosure 13, and the data transmission element 318 is electrically connected to the antenna 330. The data transmission element 318 is disposed inside the housing 311, and the housing 311 at least partially protrudes from the outside of the enclosure 13. The antenna 330 is installed on the portion of the housing 311 located outside the enclosure 13.

[0140] The housing 311 is a supporting and housing component for the data transmission element 318. The housing 311 has a receiving cavity, in which the data transmission element 318 and the antenna 330 can be housed. The housing 311 can be composed of two parts that are snapped together. These two parts can be detachably connected or non-detachably connected by means of bonding, welding, etc.

[0141] For example, the box body 311 may include a box body and a box lid. The box body has an opening, and the box lid is placed on the box body to form a receiving cavity. The box body is connected to the box body 13, and the opening of the box body faces the side away from the box body 13. The box body and the box lid may be sealed with glue and fixed with screws or other fasteners.

[0142] For example, such as Figures 8 to 11As shown, the box body 311 can also include a base 316 and a cover 315, the cover 315 covers the base 316 to form a containing cavity, wherein the base 316 can be connected with the box body 13, and the cover 315 is located on the side of the base 316 away from the box body 13. The base 316 and the cover 315 can be sealed by glue, a sealing ring, a sealing platform or other sealing structures, and the base 316 and the cover 315 can be fixed by screws or other fixing members.

[0143] The data transmission element 318 is a core component for realizing data transmission, which can include a circuit board and circuits and chips provided on the circuit board.

[0144] As shown, the box body 311 can be arranged on the outer wall surface of the box body 13. Figures 6 to 11

[0145] As shown, the box body 311 can be arranged on the outer wall surface of the box body 13.

[0146] As shown, the box body 311 can be arranged on the outer wall surface of the box body 13. Figures 6 to 11 As shown, the antenna 330 can be arranged in the part of the box body 311 located outside the box body 13. When the antenna 330 is arranged in the box body 311, at least the part of the box body 311 corresponding to the position of the antenna 330 can be arranged to be made of non-signal shielding material, so as to reduce the shielding effect on the signal.

[0147] As shown, the antenna 330 is arranged in the box body 311, and the main body of the box body 311 is entirely made of plastic material.

[0148] As shown, the box body 311 can be divided into a first compartment and a second compartment, the data transmission element 318 is arranged in the second compartment, the antenna 330 is arranged in the first compartment, and at least the part of the box body 311 surrounding the first compartment is made of non-conductive material. A partition plate can be arranged in the box body 311, the partition plate divides the box body 311 into the first compartment and the second compartment, the partition plate can be provided with a through hole, the through hole communicates the first compartment and the second compartment, and the connection part between the data transmission element 318 and the antenna 330 can be arranged in the through hole. By arranging the data transmission assembly 300 and the antenna 330 in different compartments, the components can be arranged reasonably, and the mutual interference between the components can be reduced. The arrangement direction of the first compartment and the second compartment can be perpendicular to the arrangement direction of the data transmission assembly 300 and the outer wall surface where the data transmission assembly 300 is arranged, so that the data transmission assembly 300 can occupy the width and length directions of the corresponding wall of the box body 13 as much as possible, and the problem that the overall space occupied by the battery device 10 is large due to the external arrangement of the data transmission assembly 300 can be reduced.
