[0023] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] In addition, to clearly illustrate the technical solution of this application, the following are also defined: Figure 1 The top, bottom, left, right, front, and back sides are shown.

[0025] like Figure 1 and Figure 2 As shown, this application provides a battery pack with a data acquisition board connection, including: at least one battery module 1, a data acquisition line 2, a slave control module 33, and a connection component 3.

[0026] Specifically, the battery modules 1 are arranged in an array. Each battery module 1 includes several battery cells 11, a mounting bracket 12, and several conductive connectors 13. The mounting bracket 12 is mounted on the top of the battery cells 11. The conductive connectors 13 are at least partially disposed on the mounting bracket 12, and adjacent battery cells 11 are connected through the conductive connectors 13. The data acquisition line 2 is mounted on the top of the mounting bracket 12 and connected to the battery cells 11. The data acquisition line 2 integrates voltage acquisition, temperature acquisition, and safety valve status acquisition functions. The slave control module 33 is disposed at the rear end of the battery module 1 array and is used to receive data information transmitted by the data acquisition line 2. The connection component 3 includes several sockets 31, several first plugs 32a, and several second plugs 32b. The first plugs 32a are fixed to the end of the data acquisition line 2 at the rear end of the array, and the sockets 31 are fixed to the slave control module 33. The number of battery modules corresponds to the total number of first plugs and second plugs.

[0027] The first plug 32a is fixed to the end of the acquisition line 2 at the rear end of the array and is plugged into the socket 31 on the slave control module 33 to achieve electrical connection;

[0028] The remaining acquisition lines 2 are fixedly connected to the second plugs 32b via flexible connectors 4, and each second plug 32b is connected to the socket 31 on the slave control module 33.

[0029] The above-mentioned design effectively reduces the manufacturing and maintenance costs of the battery pack. By reducing the use of electronic wiring harnesses and optimizing wiring methods, the space utilization rate of the battery pack is improved, which is conducive to the miniaturization and lightweight design of the battery pack. At the same time, the modular connection component 3 makes the assembly and disassembly of the battery pack easier, improving production efficiency and the convenience of subsequent maintenance. The data acquisition line 2 integrates multiple detection functions, enhancing the safety and intelligence level of the battery pack and meeting the technical requirements of modern high-performance energy storage.

[0030] Specifically, the conductive connector 13 is an aluminum conductive sheet, which is connected to the battery cell 11 by welding. Using an aluminum conductive sheet instead of the traditional copper conductive component significantly reduces material costs, making it particularly suitable for large-scale mass production. The welding connection method simplifies the installation process, improves production efficiency, and avoids potential contact problems caused by traditional bolt or plug-in methods, thus improving the stability and safety of the conductive connection.

[0031] like Figure 3 As shown, the flexible connector 4 includes a flexible flat connecting wire, which is fixedly connected to the acquisition line 2 by welding or plugging. The first plug 32a and the second plug 32b have the same structure. Using a flexible flat connecting wire as the flexible connector 4 can effectively solve the problems of limited internal space and complex wiring in the battery module 1. The flexible flat connecting wire has good flexibility and adaptability, and can be freely bent and adjusted according to the internal structure of the battery pack, reducing the space occupied by traditional wire harnesses and improving the neatness and space utilization of wiring. At the same time, the unified plug structure helps to standardize manufacturing, reduce the types of accessories and inventory costs, and simplify maintenance.

[0032] like Figure 4 As shown, the flexible connector 4 includes two parallel flexible flat connecting lines. The flexible connector 4 is fixedly connected to the acquisition line 2 by welding or plugging. The dual-line parallel structure not only optimizes the signal and power transmission channels, but also significantly improves the mechanical deformation resistance of the flexible connector 4, making it less prone to damage when subjected to external forces such as bending and squeezing, thereby improving the structural integrity and service life of the entire system.

[0033] Flexible flat connectors can be made using flexible printed circuit boards (FPCs) or flexible flat cables (FFCs).

[0034] like Figure 3As shown, the slave control module 33 is positioned perpendicular to the front-to-back direction; the socket 31 is located on the front surface of the slave control module 33, facing the battery module 1; both the first plug 32a and the second plug 32b are horizontal plate-type, and the first plug 32a and the second plug 32b are respectively horizontally connected to the socket 31 through a plate-to-plate connection. This horizontal plate-to-plate connection saves space, achieves a compact layout, reduces the connection failure rate, and improves the stability and reliability of the system. Furthermore, the horizontal plate design of the first plug 32a and the second plug 32b, combined with the horizontal insertion, facilitates operation and is suitable for automated assembly.

[0035] like Figure 5 As shown, the slave control module 33 is positioned perpendicular to the front-to-back direction; the socket 31 is located on the rear surface of the slave control module 33, with its opening facing upwards; both the first plug 32a and the second plug 32b are vertically plated, and are vertically plugged into the socket 31 respectively. This vertical plugging design effectively improves the space utilization and wiring flexibility of the battery pack, making it particularly suitable for energy storage systems with high energy density and miniaturized designs. The use of vertically plated plugs simplifies plugging and unplugging operations, facilitates assembly and maintenance, and simultaneously improves mechanical strength and electrical connection reliability.

[0036] With the above configuration, the flexible connector 4 can be applied to, for example... Figures 3 to 6 The four typical plug-in configurations are shown below:

[0037] Figure 3 Dual-wire horizontal insertion structure: Two flexible flat connecting wires are arranged in parallel, and are used in conjunction with the horizontal plug and socket 31 for horizontal insertion, which improves transmission capacity and anti-interference ability.

[0038] Figure 4 Single-wire horizontal insertion structure: It adopts a single flexible flat connecting wire, which is used in conjunction with the horizontal plate plug and socket 31 for horizontal insertion. The structure is compact and suitable for space-constrained areas.

[0039] Figure 5 Dual-line upright structure: It uses two flexible flat connecting lines, combined with upright plugs for vertical connection, which makes the structure more stable and suitable for high-density wiring.

[0040] Figure 6 Requirement for single-line vertical board structure: A single flexible flat connecting line is used, which is connected vertically by a vertical board plug and a vertical socket 31. The wiring is flexible and conducive to three-dimensional stacking.

[0041] The above-mentioned different plug-in forms, by reasonably selecting the orientation and structural layout of the plug and socket 31, take into account both electrical connection stability and installation convenience, and are suitable for different battery pack structures and assembly processes.

[0042] like Figure 3As shown, the battery pack also includes a flame sensor 5, which is mounted on the socket and faces the battery module 1. The flame sensor 5 can detect arcing at the terminal of the battery cell 11 and output an alarm signal to the slave control module 33, thereby improving the system's active safety protection capability. Especially during high-power charging and discharging, it can effectively prevent arcing and fire accidents caused by local overheating or loosening.

[0043] The battery pack also includes a temperature and humidity sensor 6, which is installed on the socket to enable dynamic monitoring and intelligent management of the battery pack's operating environment, significantly improving the system's safety and reliability. Especially under complex operating conditions such as high temperature and high humidity, it can effectively prevent battery performance degradation, shortened lifespan, and potential safety risks caused by environmental deterioration.

[0044] like Figure 7 As shown, the mounting bracket 13 is equipped with an expansion detection element 7, which is electrically connected to the acquisition line 2. The expansion detection element 7 is used to output an electrical signal to indicate the expansion state when the acquisition line 2 deforms due to the expansion of the battery cell. By monitoring the expansion state of the battery cell 11 in real time, problems can be detected in time before the battery cell 11 fails or malfunctions, preventing safety events such as short circuits, leaks, and thermal runaway caused by the expansion of the battery cell 11.

[0045] like Figure 7 and Figure 8 As shown, the feature is that a safety valve detection element 8 is provided on the acquisition line 2. The safety valve detection element 8 includes a safety valve detection sensor 81, a first safety valve detection acquisition line 82, and a second safety valve detection acquisition line 83. Both the first and second safety valve detection acquisition lines 82 and 83 are mounted on the safety valve detection element 8 and are separated from each other. When a leak occurs in the safety valve, the wiring inside the safety valve detection element 8 contacts the liquid in the safety valve, and a corresponding electrical signal is output to the acquisition line 2, improving the safety of equipment operation. The safety valve detection element 8 is electrically connected to the acquisition line 2. The first and second safety valve detection acquisition lines 82 and 83 are arranged in a fan-shaped pattern on the corresponding area of ​​the battery cell's safety valve portion, and are intersecting but not connected, and are respectively connected to the acquisition line 2 through an S-shaped winding connection path. This prevents the safety valve detection sensor 81 from being torn and damaged due to battery deformation, improving the stability of the structure.
