Description

Technical Field

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

[0002] In current battery pack designs, many long battery packs, such as H-packs and AD-packs, place the battery management system (BMS) controller between two internal module areas. This layout requires an object or device to transmit BMS data from the center of the battery pack to the front panel, facilitating connection and data exchange between the battery pack and external communication components.

[0003] The current solution primarily implements this functionality through a single communication harness. Specifically, this harness extends from the BMS controller, located between the two module areas, to the front panel of the battery pack. This harness transmits BMS data from the center of the battery pack to the front panel, enabling the battery pack to connect and exchange data with external communication components. This simple and direct solution effectively transmits BMS data and ensures smooth communication between the battery pack and external systems.

[0004] However, the wiring harness for these communication cables requires cost, significantly increasing the price of the battery pack. Furthermore, this wiring harness needs to be secured to the CCS assembly with cable ties, increasing the labor cost of securing the harness during installation. Furthermore, when the wiring harness runs along the top of the module, it takes up space in the Z direction, reducing the battery pack's space utilization. Utility Model Content

[0005] This application provides a wiring assembly, battery pack, and electrical equipment that can reduce the use of wiring harnesses and lower costs. The integrated design of the test circuit board and communication lines eliminates the need for cable tie fixation and other procedures, reducing the labor cost of securing the wiring harness. Because the communication lines no longer occupy the Z-direction space of the module, the space utilization of the battery pack is reduced.

[0006] In a first aspect, the present application provides a wiring assembly, comprising a detection circuit board and a communication line. A first plug and a second plug are provided at both ends of the detection circuit board, respectively, wherein the first plug is directly or indirectly connected to a power manager;

[0007] The communication circuit is integrated into the detection circuit board, and the two ends of the communication circuit are respectively connected to the first plug and the second plug; the communication circuit and the detection circuit board are integrally arranged, and the communication circuit is connected to the communication socket through the second plug.

[0008] This structure reduces the need for wiring harnesses for communication lines, lowering costs. The integrated design of the test circuit board and communication lines eliminates the need for cable tie fixation, reducing labor costs for securing the harnesses. Because the communication lines no longer occupy Z-axis space within the module, battery pack space utilization is reduced.

[0009] Specifically, the communication circuitry, tightly integrated with the detection circuit board, plays a crucial role in the wiring assembly. The communication circuitry runs between the circuit boards, tightly connecting the first and second plugs, forming an efficient and stable data transmission channel. Compared to traditional independent wiring methods, this integrated design not only reduces wiring harness usage and costs, but also significantly improves space utilization. The integrated design of the communication circuitry and detection circuit board makes the entire wiring assembly more compact and aesthetically pleasing, while also reducing potential safety hazards associated with disorganized wiring harnesses.

[0010] The connection between the communication line and the second plug provides strong support for the device's communication capabilities. Whether interacting with other internal components or connecting to external devices, this efficient data transmission channel is achieved. This design not only improves the device's responsiveness but also enhances overall system performance, providing users with a smoother and more convenient user experience.

[0011] In some examples, the detection circuit board is a flexible circuit board, or the detection circuit board is a rigid circuit board.

[0012] FPC is used in electronic devices that require high integration and compact space due to its excellent flexibility, lightness and good electrical performance. The application of FPC is particularly prominent in wiring components. Compared with traditional rigid circuit boards, FPC can fit tightly into the complex and changeable shapes inside the battery pack, reduce space occupancy, and improve the flexibility of the overall design. For example, inside the AD box, due to limited space and the need to accommodate multiple small modules (usually 6 small modules, and H box may have up to 8 small modules), FPC can flexibly pass through the narrow gaps between modules to collect the voltage and temperature data of the battery cells without being restricted by physical space.

[0013] In applications requiring higher stability and load-bearing capacity, PCBs demonstrate their irreplaceable value. With their robust substrate material and stable electrical connections, PCBs ensure reliable and durable data transmission. In wiring assemblies, PCBs may be used in critical control modules or interfaces, ensuring stable operation of the entire system. While PCBs may occupy less space than FPCs, the stability and reliability they provide are crucial to the long-term operation of a system.

[0014] Whether FPC or PCB, they are closely connected to the communication lines in the wiring assembly, together forming an efficient data transmission network. In the design mentioned in this article, the communication lines are simplified and integrated by integrating the communication lines with the detection circuit board (FPC or PCB) and directly connecting them to the communication socket via a second plug. This innovative design not only reduces the use of traditional wiring harnesses, reducing material and manufacturing costs, but also avoids the complex cable tie fixing process, further saving labor costs.

[0015] In some examples, the communication line is disposed in a central region of the detection circuit board, and at least one voltage collection area and at least one temperature collection area are respectively disposed on two sides of the central region.

[0016] Placing the communication lines in the center of the test circuit board leverages the board's spatial layout, achieving efficient and convenient signal transmission. As the core area of ​​the board, this central location not only facilitates connections with other functional modules but also effectively reduces interference and attenuation during signal transmission. This layout ensures the stability and reliability of the communication lines, providing a solid communication foundation for the entire battery management system.

[0017] At least one voltage collection area is set up on both sides of the communication line. This design reflects the monitoring of battery cell voltage. Voltage is one of the important parameters reflecting the operating status of battery cells. By accurately measuring the voltage value, the charge and discharge status of the battery cell, capacity decay, and whether there are abnormal conditions such as overcharge and overdischarge can be understood in real time. The voltage collection area is usually equipped with a high-precision voltage sensor and analog-to-digital converter (ADC), which can achieve fast and accurate acquisition of battery cell voltage. In addition, to further improve measurement accuracy, the voltage collection area also uses signal conditioning technologies such as differential amplifier circuits to amplify and filter the collected voltage signals.

[0018] In some examples, the voltage collection area is provided with a voltage collection element, and the temperature collection area is provided with a temperature collection element. The voltage collection element and the temperature collection element are directly or indirectly connected to the power manager through a first plug, or the voltage collection element and the temperature collection element are directly or indirectly connected to the communication socket through a second plug.

[0019] Accurate voltage and temperature monitoring is crucial for ensuring stable equipment operation and extending its lifespan. This process requires highly integrated sensors and intelligent management systems. A closer look at the internal structure of some advanced electronic devices reveals dedicated voltage and temperature acquisition areas, each with its own distinct functions.

[0020] Advanced voltage acquisition components are deployed within the voltage collection area. They constantly monitor voltage changes at every critical node in the circuit. Utilizing sophisticated circuit design and highly sensitive materials, they can capture even the slightest voltage fluctuations, ensuring accurate data. This voltage data not only reflects the current operating status of the equipment but also provides valuable insight for fault prediction and maintenance. Through the ingenious design of the first plug, these voltage acquisition components can be directly or indirectly connected to the power manager, enabling real-time data transmission and processing.

[0021] Meanwhile, specialized temperature acquisition components are deployed within the temperature collection area. These components utilize principles such as thermistors and thermocouples to convert temperature changes within the device into measurable electrical signals. Equipped with high sensitivity and precision, they can rapidly respond to temperature fluctuations and provide comprehensive temperature monitoring for the device. These temperature acquisition components are particularly critical in extreme operating environments, enabling timely detection and reporting of potential issues like overheating, preventing damage to the device. Similarly, this temperature data is connected to the power manager via the first plug, enabling centralized data processing and analysis.

[0022] In some examples, the detection circuit board is a double-sided circuit board, which includes a first fabric layer and a second fabric layer. The voltage collection element and the temperature collection element are both arranged in the first fabric layer, and the communication line is arranged in the second fabric layer.

[0023] Double-sided PCBs are constructed from two primary fabric layers: the primary and secondary. These layers are tightly bonded together through sophisticated manufacturing processes, forming a stable and efficient circuit carrier. The primary fabric layer typically houses a series of precision voltage and temperature sensing components. These constantly monitor and collect voltage and temperature data during circuit operation, providing critical data support for stable system operation.

[0024] Meanwhile, on the second fabric layer of the double-sided PCB, communication lines are responsible for efficiently and accurately transmitting information between components and between the PCB and external devices. They utilize advanced wiring techniques and materials to ensure stable and reliable signal transmission. Furthermore, to further enhance communication efficiency, the communication lines employ advanced technologies such as a multi-layer structure and differential signal transmission, effectively reducing signal interference and transmission delays.

[0025] In some examples, the first fabric layer is disposed on a side of the double-sided circuit board facing away from the battery cell assembly, and the second fabric layer is disposed on a side of the double-sided circuit board close to the battery cell assembly.

[0026] The design and layout of circuit boards are crucial, not only as a bridge connecting various electronic components but also as a key to ensuring stable device operation. Double-sided circuit boards, with their unique dual-layer structure, enable components to be arranged on both sides of the board, effectively improving space utilization and circuit integration. In this design context, layout strategies for the component layers, particularly those near battery cells, warrant further discussion.

[0027] Specifically, when the double-sided circuit board and the battery cell components are laid out in a coordinated manner, the setting of the fabric layer becomes a detail that cannot be ignored. It can be clearly seen that in order to maximize performance and safety, the first fabric layer is set on the side of the double-sided circuit board away from the battery cell components. This layout strategy is not arbitrary, but is based on multiple considerations: first, it helps to reduce direct heat conduction between the fabric layer and the battery cell components, thereby reducing performance degradation or safety hazards caused by high temperature; second, the layout away from the battery cell components also reserves more space for subsequent heat dissipation design, making the thermal management of the entire system more efficient; third, from the perspective of electromagnetic compatibility, such a layout helps to reduce electromagnetic interference and ensure stable signal transmission.

[0028] In some examples, the communication line is integrated on the detection circuit board and is conducted through copper foil on the detection circuit board.

[0029] This structure can reduce the need for wiring harnesses for communication lines, thus lowering costs. In practical applications, communication lines are often embedded in the multilayer structure of a test circuit board in the form of fine wires. These wires, like an intricate neural network, precisely connect the various functional modules of the circuit board. Copper foil, a highly conductive and ductile metal material, is widely used in circuit board construction. It not only has excellent electrical properties but also effectively resists oxidation and corrosion, ensuring stable transmission of communication signals.

[0030] In some examples, a wire structure is provided on the second plug, and an end of the wire structure away from the second plug is connected to the communication socket.

[0031] As an efficient and compact connection method, the conductor structure typically consists of multiple fine conductors arranged in parallel, coated with an insulating material to protect the wires from external interference and abrasion. On the second plug, the conductor structure is embedded or fixed inside the plug, ensuring both compactness and connection reliability. Through sophisticated manufacturing processes, each wire of the conductor structure accurately aligns with the corresponding contact on the communication socket, achieving precise signal transmission.

[0032] In a second aspect, the present application provides a battery pack comprising the above-mentioned wiring assembly and a box body, wherein the wiring assembly is disposed in the box body.

[0033] Battery packs with these wiring assemblies can reduce the need for wiring harnesses for communication lines, lowering costs. The integrated design of the test circuit board and communication lines eliminates the need for cable tie fixation, reducing labor costs for securing the wiring harnesses. Because the communication lines no longer occupy Z-axis space within the module, the battery pack's space utilization is reduced.

[0034] In a third aspect, the present application provides an electrical device, comprising the above-mentioned battery pack and a device body, wherein the battery pack is arranged in the device body.

[0035] Electrical equipment equipped with this battery pack can reduce the use of wiring harnesses for communication lines, lowering costs. The integrated design of the test circuit board and communication lines eliminates the need for cable tie fixation, reducing labor costs for securing the wiring harnesses. Because the communication lines no longer occupy the Z-axis space of the module, the space utilization of the battery pack is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] In order to make the purpose, technical solutions and advantages of this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific examples described herein are only used to explain this application and are not intended to limit this application.

[0047] To solve the above technical problems, please refer to Figure 1-Figure 7 As shown, the first aspect of the present application proposes a wiring assembly 100 that can reduce the use of wiring harnesses corresponding to the communication circuit 140, thereby reducing costs. After the detection circuit board 110 and the communication circuit 140 are integrated, the process of fixing with cable ties and the like is no longer required, thus reducing the labor cost of fixing the wiring harness. Since the communication circuit 140 no longer occupies the Z-direction space of the module, the space utilization rate of the battery pack is reduced.

[0048] Reference Figures 1-4 As shown, in some examples, the wiring assembly 100 includes a detection circuit board 110 and a communication line 140. A first plug 120 and a second plug 130 are respectively provided at both ends of the detection circuit board 110, and the first plug 120 is directly or indirectly connected to the power manager;

[0049] The communication line 140 is integrated into the detection circuit board 110 , and the two ends of the communication line 140 are respectively connected to the first plug 120 and the second plug 130 ; the communication line 140 is integrally arranged with the detection circuit board 110 , and the communication line 140 is connected to the communication socket 300 through the second plug 130 .

[0050] This structure reduces the need for wiring harnesses for the communication circuit 140, lowering costs. The integrated design of the detection circuit board 110 and communication circuit 140 eliminates the need for cable tie fixation, reducing labor costs for securing the wiring harness. Since the communication circuit 140 no longer occupies Z-axis space within the module, battery pack space utilization is reduced.

[0051] The wiring assembly 100 can serve as a link connecting various components. The wiring assembly 100 plays an important role in improving product performance, reducing costs and optimizing space utilization.

[0052] The detection circuit board 110 is terminated with a first plug 120 and a second plug 130. The first plug 120 interfaces with the power management unit, ensuring a stable and reliable power supply. The second plug 130 facilitates communication with the communication line 140 and external devices, ensuring efficient and accurate information transmission.

[0053] The design of first plug 120 fully considers the compatibility and compatibility between the power manager and detection circuit board 110. It utilizes stable plug-in / out technology to ensure stable power transmission even in complex operating environments. Furthermore, through precise dimensional control and material selection, the placement of first plug 120 not only effectively reduces contact resistance but also improves plug-in durability, reducing wear and tear caused by frequent plugging and unplugging. This design not only extends the device's lifespan but also reduces maintenance costs, providing users with a more reliable experience.

[0054] The communication line 140, which is tightly integrated with the detection circuit board 110, is an important part of the wiring assembly 100. Specifically, the communication line 140 runs between the circuit boards, tightly connecting the first plug 120 and the second plug 130, forming an efficient and stable data transmission channel. Compared with the traditional independent wiring method, this integrated design not only reduces the use of wiring harnesses and reduces costs, but also greatly improves space utilization. The integrated setting of the communication line 140 and the detection circuit board 110 makes the entire wiring assembly 100 more compact and beautiful, while also reducing the safety hazards that may be caused by the disorganized wiring harness.

[0055] The connection between communication line 140 and second plug 130 provides strong support for the device's communication capabilities. Whether interacting with other internal components or connecting to external devices, this efficient data transmission channel enables both. This design not only improves the device's responsiveness but also enhances overall system performance, providing users with a smoother and more convenient user experience.

[0056] Reference Figure 5-Figure 7As shown, in some examples, the detection circuit board 110 is a flexible printed circuit board (FPC), or the detection circuit board 110 is a rigid printed circuit board (PCB). The above different detection circuit boards 110 can all have the communication line 140 integrated with the detection circuit board 110, and the communication line 140 is connected to the communication socket 300 through the second plug 130.

[0057] FPC is used in electronic devices that require high integration and compact space due to its excellent flexibility, lightness and good electrical performance. In the wiring assembly 100, the application of FPC is particularly prominent. Compared with traditional rigid circuit boards, FPC can fit tightly into the complex and changeable shapes inside the battery pack, reduce space occupancy, and enhance the flexibility of the overall design. For example, inside the AD box 400, due to limited space and the need to accommodate multiple small modules (usually 6 small modules, and H boxes may have up to 8), FPC can flexibly pass through the narrow gaps between modules to collect the voltage and temperature data of the battery cells without being restricted by physical space.

[0058] In applications requiring higher stability and load-bearing capacity, PCBs demonstrate their irreplaceable value. With its robust substrate and stable electrical connections, PCBs ensure reliable and durable data transmission. In wiring assembly 100, PCBs may be used in critical control modules or interfaces, ensuring stable operation of the entire system. While PCBs may occupy less space than FPCs, the stability and reliability they provide are crucial to the long-term operation of the system.

[0059] Whether FPC or PCB, within the wiring assembly 100, they are tightly connected to the communication line 140, forming a highly efficient data transmission network. The design described herein simplifies and integrates the communication line 140 by integrating it with the detection circuit board 110 (FPC or PCB) and directly connecting it to the communication socket 300 via the second plug 130. This innovative design not only reduces the use of traditional wiring harnesses, lowering material and manufacturing costs, but also avoids the complex process of cable tie fixing, further saving labor costs.

[0060] Specifically, the internal structural layout of the AD box 400 is particularly ingenious, especially the FPC design on the three front modules. These FPCs are equipped with two plugs, located at the front and back of the module, which not only facilitates data collection but also enables two-way transmission of communication data. The added internal copper foil serves as a communication medium, replacing the traditional wiring harness, further improving the efficiency and stability of data transmission. This design not only reduces the space occupied by the wiring harness, but also improves the space utilization of the battery pack, making the overall design more compact and efficient.

[0061] In summary, both the FPC and the PCB play an indispensable role in the wiring assembly 100. By optimizing the layout of the communication line 140 and adopting an integrated design, not only the cost is reduced and the efficiency is improved, but also the space utilization of the battery pack is improved.

[0062] Reference Figure 5-Figure 7 As shown, in some examples, the communication line 140 is disposed in the central region of the detection circuit board 110, with at least one voltage collection area and at least one temperature collection area disposed on either side of the central region. The voltage collection area can detect the voltage of the battery cells in the battery cell assembly 200, and the temperature collection area can detect the temperature of the battery cells in the battery cell assembly 200. The communication line 140 facilitates communication.

[0063] Placing communication line 140 in the central area of ​​detection circuit board 110 leverages the circuit board's spatial layout, achieving efficient and convenient signal transmission. As the core area of ​​the circuit board, the central area not only facilitates connections with other functional modules but also effectively reduces interference and attenuation during signal transmission. This layout ensures the stability and reliability of communication line 140, providing a solid communication foundation for the entire battery management system.

[0064] At least one voltage acquisition area is set on both sides of the communication line 140. This design reflects the monitoring of the battery cell voltage. Voltage is one of the important parameters that reflect the working status of the battery cell. By accurately measuring the voltage value, the charge and discharge status of the battery cell, the capacity attenuation, and whether there are abnormal conditions such as overcharging and over-discharging can be grasped in real time. The voltage acquisition area is usually equipped with a high-precision voltage sensor and an analog-to-digital converter (ADC), which can realize the fast and accurate acquisition of the battery cell voltage. In addition, in order to further improve the accuracy of the measurement, the voltage acquisition area will also use signal conditioning technologies such as differential amplifier circuits to amplify, filter, and process the collected voltage signals.

[0065] Corresponding to the voltage acquisition area, the temperature acquisition area is responsible for real-time monitoring of battery cell temperature. Temperature is a key factor affecting battery performance and safety; both excessively high and low temperatures can damage the battery. Therefore, establishing a temperature acquisition area in the battery management system is particularly important. This area is typically equipped with temperature sensors, such as thermistors, thermocouples, or integrated temperature sensors. These sensors can sense changes in battery cell temperature in real time and convert the temperature signals into electrical signals for transmission. By collecting and analyzing temperature signals, the system can promptly detect and address abnormal conditions such as battery overheating and overcooling, ensuring safe battery operation.

[0066] This layout design, with communication line 140 positioned in the center and voltage and temperature collection areas on either side, offers numerous advantages. First, it improves system integration and compactness, making the entire battery management system more compact and lightweight. Second, it optimizes signal transmission paths and quality, improving system response speed and accuracy. Finally, it enables comprehensive monitoring and protection of cell voltage and temperature, providing a strong guarantee for safe battery operation.

[0067] Taking electric vehicles as an example, their battery management systems typically adopt this layout design. During the operation of the electric vehicle, the battery management system needs to monitor the voltage and temperature of the battery pack in real time to ensure the safety and stability of the battery pack. By placing the communication line 140 in the central area of ​​the detection circuit board 110 and providing voltage and temperature collection areas on both sides, the electric vehicle's battery management system can achieve precise monitoring and control of each battery cell unit. This not only improves the electric vehicle's range and power performance, but also significantly reduces the risk of battery failure and safety accidents.

[0068] In summary, the layout design of placing communication line 140 in the center of detection circuit board 110, with voltage and temperature acquisition areas on either side, is an efficient and reliable solution for modern battery management systems. It fully utilizes the circuit board's space resources, enabling comprehensive monitoring and protection of cell voltage and temperature, providing strong support for safe battery operation and efficient management.

[0069] Reference Figure 5-Figure 7 As shown, in some examples, the voltage collection area is provided with a voltage collection element 113, and the temperature collection area is provided with a temperature collection element. The voltage collection element 113 and the temperature collection element are directly or indirectly connected to the power manager through the first plug 120, or the voltage collection element 113 and the temperature collection element are directly or indirectly connected to the communication socket through the second plug 130.

[0070] Accurate voltage and temperature monitoring is crucial for ensuring stable equipment operation and extending its lifespan. This process requires highly integrated sensors and intelligent management systems. A closer look at the internal structure of some advanced electronic devices reveals dedicated voltage and temperature acquisition areas, each with its own distinct functions.

[0071] Advanced voltage collection components 113 are located within the voltage collection area. They constantly monitor voltage changes at every critical node in the circuit. Utilizing sophisticated circuit design and highly sensitive materials, they can capture even the slightest voltage fluctuations, ensuring accurate data. This voltage data not only reflects the current operating status of the equipment but also provides valuable insight for fault prediction and maintenance. Through the ingenious design of the first plug 120, these voltage collection components 113 can be directly or indirectly connected to the power manager, enabling real-time data transmission and processing.

[0072] Meanwhile, specialized temperature acquisition components are deployed within the temperature collection area. These components utilize principles such as thermistors and thermocouples to convert temperature changes within the device into measurable electrical signals. Equally sensitive and precise, they can rapidly respond to temperature fluctuations and provide comprehensive temperature monitoring for the device. These temperature acquisition components are particularly critical in extreme operating environments, enabling timely detection and reporting of potential issues like overheating, preventing damage to the device due to excessive temperatures. Similarly, this temperature data is connected to the power manager via the first plug 120, enabling centralized data processing and analysis.

[0073] It's worth noting that the first plug 120 or the second plug 130, which serves as a bridge connecting the voltage acquisition element 113, the temperature acquisition element, and the power manager, has also been meticulously designed. This not only ensures stable and reliable data transmission, but also balances the rational use of internal space and aesthetically pleasing wiring. In practical applications, the first plug 120 typically utilizes high-quality materials and advanced manufacturing processes to ensure long-term stable operation in harsh operating environments.

[0074] Furthermore, with the rapid development of the Internet of Things and big data technologies, voltage and temperature monitoring is no longer limited to individual devices. An increasing number of electronic devices are now supporting remote monitoring and data analysis. By connecting these voltage and temperature acquisition components 113 to cloud servers, real-time monitoring and data analysis of device status can be achieved. This not only improves the efficiency and accuracy of equipment maintenance but also provides strong support for intelligent management and decision-making in enterprises.

[0075] In summary, the voltage and temperature acquisition components 113 and 114 play a crucial role in electronic devices. They are closely connected to the power manager via the first plug 120, forming an efficient and accurate monitoring system. Every detail of this system has been meticulously designed and optimized to ensure that the device maintains optimal performance in complex and changing operating environments.

[0076] Reference Figure 6-Figure 7 As shown, in some examples, the detection circuit board 110 is a double-sided circuit board, which includes a first fabric layer 111 and a second fabric layer 112, the voltage collection element 113 and the temperature collection element are both arranged on the first fabric layer 111, and the communication line 140 is arranged on the second fabric layer 112.

[0077] Double-sided circuit boards are constructed from two primary fabric layers: a first fabric layer 111 and a second fabric layer 112. These two layers are tightly bonded together through sophisticated manufacturing processes, forming a stable and efficient circuit carrier. On the first fabric layer 111, you'll typically find a series of precision voltage and temperature acquisition components 113. These constantly monitor and collect voltage and temperature data during circuit operation, providing critical data support for stable system operation.

[0078] Meanwhile, on the second fabric layer 112 of the double-sided circuit board, communication lines 140 are responsible for efficiently and accurately transmitting information between components and between the circuit board and external devices. They utilize advanced wiring techniques and materials to ensure stable and reliable signal transmission. Furthermore, to further enhance communication efficiency, communication lines 140 employ advanced technologies such as a multi-layer structure and differential signal transmission, effectively reducing signal interference and transmission delay.

[0079] A double-layer layout allows for more compact arrangement of components and circuits on a circuit board, significantly improving circuit integration and space utilization. This is particularly important for electronic devices with strict requirements for size and weight. Furthermore, a double-layer layout allows for more flexible interconnection and layout of components and circuits on the circuit board, reducing design complexity and manufacturing costs. Last but not least, a double-layer layout also improves the board's heat dissipation performance. Due to the gaps and heat dissipation channels between the two layers, heat can be dissipated more quickly, ensuring stable circuit operation and extending component life.

[0080] In some examples, the first fabric layer 111 is disposed on a side of the double-sided circuit board facing away from the battery cell assembly 200 , and the second fabric layer 112 is disposed on a side of the double-sided circuit board close to the battery cell assembly 200 .

[0081] The design and layout of circuit boards are particularly important. They not only serve as a bridge connecting various electronic components but are also crucial for ensuring stable device operation. Double-sided circuit boards, with their unique dual-layer structure, enable components to be arranged on both sides of the same board, effectively improving space utilization and circuit integration. In this design context, the layout strategies for the component layers, particularly those near the battery cell assembly 200, are worthy of in-depth discussion.

[0082] Specifically, when the double-sided circuit board and the battery cell assembly 200 are laid out in coordination, the setting of the fabric layer becomes a detail that cannot be ignored. It can be clearly seen that in order to maximize the optimization of performance and safety, the first fabric layer 111 is set on the side of the double-sided circuit board away from the battery cell assembly 200. This layout strategy is not arbitrary, but is based on multiple considerations: first, it helps to reduce direct heat conduction between the fabric layer and the battery cell assembly 200, thereby reducing performance degradation or safety hazards caused by high temperature; secondly, the layout away from the battery cell assembly 200 also reserves more space for subsequent heat dissipation design, making the thermal management of the entire system more efficient; thirdly, from the perspective of electromagnetic compatibility, such a layout helps to reduce electromagnetic interference and ensure stable signal transmission.

[0083] The second fabric layer 112 is positioned on the side of the double-sided circuit board closest to the battery cell assembly 200. This proximity to the battery cell assembly 200 allows the second fabric layer 112 to more directly participate in monitoring and protecting the battery cell assembly 200. For example, by placing temperature sensors or voltage detection circuits on this layer, the operating status of the battery cell assembly 200 can be monitored in real time, allowing potential anomalies to be detected and addressed promptly. Furthermore, the second fabric layer 112 may also provide a stable voltage or current for the battery cell assembly 200, ensuring optimal operation.

[0084] In some examples, the communication line 140 is integrated on the detection circuit board 110 and is conducted through the copper foil on the detection circuit board 110 .

[0085] This structure can reduce the amount of wiring required for communication line 140, lowering costs. In practical applications, communication line 140 is often embedded within the multilayer structure of detection circuit board 110 in the form of fine wires. These wires, like a complex neural network, precisely connect the various functional modules of the circuit board. Copper foil, a highly conductive and ductile metal material, is widely used in circuit board manufacturing. It not only has excellent electrical properties but also effectively resists oxidation and corrosion, ensuring stable transmission of communication signals.

[0086] In some examples, a wire structure is provided on the second plug 130 , and an end of the wire structure away from the second plug 130 is connected to the communication socket 300 .

[0087] As an efficient and compact connection method, a wire structure typically consists of multiple fine conductors arranged in parallel and coated with an insulating material to protect the conductors from external interference and abrasion. On the second plug 130, the wire structure is embedded or fixed within the plug, ensuring both a compact structure and a reliable connection. Through sophisticated manufacturing processes, each wire in the wire structure accurately aligns with the corresponding contact on the communication socket 300, thereby achieving precise signal transmission.

[0088] The end of the wire structure away from the second plug 130 is connected to the communication socket 300 through a series of precise layout and connection technologies. In this process, many factors need to be considered, such as signal attenuation, interference suppression, and connection stability. In order to reduce the attenuation of the signal during transmission, the wire structure is often made of low-impedance, high-transmission-rate materials; at the same time, through reasonable wiring design and shielding measures, the influence of external electromagnetic interference on the signal is effectively suppressed. In addition, in order to ensure the stability of the connection, the interface between the wire structure and the communication socket 300 usually adopts a connector with moderate plug-in and pull-out force and reliable contact to ensure that it can maintain a good connection after multiple plug-ins and pull-outs.

[0089] The application of wire structure in communication equipment not only improves the connection efficiency and signal transmission quality of the equipment, but also greatly simplifies the layout and wiring of the equipment.

[0090] In a second aspect, the present application provides a battery pack comprising the aforementioned wiring assembly 100 and a housing 400, wherein the wiring assembly 100 is disposed within the housing 400. The battery pack of the present application may include two cell modules, namely a first module 210 and a second module 220, both of which are mounted within the housing 400.

A slave control structure of a power manager may be disposed between the first module 210 and the second module 220.

[0091] A battery pack with the aforementioned wiring assembly 100 can reduce the amount of wiring harnesses required for the communication circuit 140, thus lowering costs. The integrated design of the detection circuit board 110 and communication circuit 140 eliminates the need for cable tie fixation, reducing labor costs associated with securing the wiring harness. Since the communication circuit 140 no longer occupies Z-axis space within the module, the battery pack's space utilization is reduced.
