Description

Technical Field

[0001] This utility model relates to the field of battery cell module structure design technology, and more specifically, to a battery cell module and a battery having the same. Background Technology

[0002] In existing technologies, PCBs (printed circuit boards) are typically used as CCS (integrated busbars), and the acquisition of battery voltage and temperature usually relies on PCBs as core components. This PCB busbar and signal acquisition method has the following significant drawbacks:

[0003] 1. Large space occupation: Due to the rigid nature of PCBs, they often require a large planar area to accommodate all the necessary electronic components and circuits. However, inside modern electric vehicle battery packs, space is very limited due to the need to accommodate a large number of battery cells. Therefore, the use of PCBs further compresses the available space, limiting the overall design flexibility and efficiency of the battery pack.

[0004] 2. Limited electrical performance: In the dense arrangement of battery cells, the PCB needs to be connected to various temperature and voltage points by soldering. However, this connection method is easily affected by vibration and thermal expansion and contraction, which can lead to poor contact or even open circuit, thereby affecting the electrical performance and stability of the entire battery system.

[0005] 3. High cost: The manufacturing process of PCBs is complex, requiring precise circuit design, photolithography, etching, and other steps, all of which increase production costs. Furthermore, due to the fixed size of PCBs, when the battery pack design changes, it may be necessary to customize the PCB, adding extra expenses.

[0006] There is currently no effective solution to the aforementioned problems in the existing technology. Utility Model Content

[0008] To achieve the above objectives, according to one aspect of the present invention, a battery cell module is provided, comprising: a battery cell unit, wherein multiple battery cell units are stacked along a first direction; an insulating tray, wherein the insulating tray is located on top of the multiple battery cell units; a series aluminum busbar, wherein multiple series aluminum busbars are located on top of the insulating tray and connected to the insulating tray, wherein both ends of the series aluminum busbars are electrically connected to two adjacent battery cell units along the first direction, thereby connecting the two battery cell units in series; a module output terminal, wherein the module output terminal is electrically connected to the outermost battery cell unit along the first direction among the multiple battery cell units; and a signal acquisition harness, wherein the signal acquisition harness is located on top of the insulating tray and is electrically connected to at least one series aluminum busbar, and the signal acquisition harness is connected to the insulating tray.

[0009] Furthermore, the multiple series-connected aluminum busbars include a first aluminum busbar group and a second aluminum busbar group. The first aluminum busbar group and the second aluminum busbar group are arranged opposite to each other along a second direction. The first aluminum busbar group is located on the first side of the insulating tray, and the second aluminum busbar group is located on the second side of the insulating tray. The first aluminum busbar group and the second aluminum busbar group are staggered. The series-connected aluminum busbars in the first aluminum busbar group are used to electrically connect the poles of two adjacent battery cells close to the first side, and the series-connected aluminum busbars in the second aluminum busbar group are used to electrically connect the poles of two adjacent battery cells close to the second side.

[0010] Furthermore, the first direction is the length direction of the insulating tray, and / or the second direction is the width direction of the insulating tray.

[0011] Furthermore, the insulating tray is provided with multiple aluminum busbar through holes, and the multiple aluminum busbar through holes are set one-to-one with the ends of multiple series aluminum busbars, so that the ends of each series aluminum busbar can be electrically connected to the corresponding battery cell through the aluminum busbar through holes.

[0012] Furthermore, the signal acquisition harness includes a voltage acquisition harness and a temperature acquisition harness. One end of the voltage acquisition harness is electrically connected to a series aluminum busbar, and the other end of the voltage acquisition harness is connected to a connector. One end of the temperature acquisition harness is electrically connected to a series aluminum busbar, and the other end of the temperature acquisition harness is connected to a connector. A wiring space is provided in the middle of the insulating tray, and the wiring space extends along a first direction. At least a portion of the voltage acquisition harness is located within the wiring space, and / or, at least a portion of the temperature acquisition harness is located within the wiring space.

[0013] Furthermore, a wire-passing groove is provided in the middle of the insulating tray, which extends along the first direction and forms a wiring space.

[0014] Furthermore, both the voltage acquisition harness and the temperature acquisition harness are bound to the wiring space with tape.

[0015] Furthermore, each series aluminum busbar is bonded to the insulating tray with adhesive.

[0016] Furthermore, the module output terminals include a module positive current bus and a module negative current bus. The module positive current bus and the module negative current bus are located at both ends of the insulating tray along the first direction, respectively. Both the module positive current bus and the module negative current bus are connected to the insulating tray. The module positive current bus is electrically connected to the outermost cell among the multiple cell units along the first direction, and the module negative current bus is electrically connected to the other cell unit among the multiple cell units along the first direction.

[0017] According to one aspect of the present invention, a battery is provided, comprising a plurality of battery cell modules arranged in parallel, wherein the battery cell modules are as described above.

[0043] In traditional electric vehicle battery management systems (BMS), battery voltage and temperature data acquisition typically relies on printed circuit boards (PCBs) as the core component. This approach is space-consuming, costly, and has limited electrical performance, and also suffers from the following significant drawbacks:

[0044] Low assembly efficiency: The installation and debugging of PCBs require professional technicians and may involve complex wire management and signal testing, which not only consumes time but also increases workload and reduces the efficiency of the production line.

[0045] Poor versatility: Existing PCB acquisition systems are often designed for specific battery packs, making it difficult to adapt to the rapid changes in different battery models and capacity requirements, thus limiting their application scope across different vehicle models and projects.

[0046] Given the aforementioned technical shortcomings, there is an urgent need for a new solution that can overcome the limitations of PCB acquisition, improve the reliability, cost-effectiveness, and versatility of the battery management system, and optimize the overall design of the battery pack, thereby enabling electric vehicles to achieve greater performance and economic benefits.

[0047] Combination Figures 1 to 4 As shown, according to a specific embodiment of this application, a battery cell module is provided, comprising: a battery cell unit, wherein multiple battery cell units are stacked along a first direction; an insulating tray 2, wherein the insulating tray 2 is located on top of the multiple battery cell units; a series aluminum busbar 1, wherein there are multiple series aluminum busbars 1, wherein the series aluminum busbar 1 is located on top of the insulating tray 2 and connected to the insulating tray 2, wherein both ends of the series aluminum busbar 1 are electrically connected to two adjacent battery cell units along the first direction to connect the two battery cell units in series; a module output terminal 100, wherein the module output terminal 100 is electrically connected to the outermost battery cell unit along the first direction among the multiple battery cell units; and a signal acquisition harness 8, wherein the signal acquisition harness 8 is located on top of the insulating tray 2 and is electrically connected to at least one series aluminum busbar 1, and is connected to the insulating tray 2.

[0048] By applying the technical solution of this utility model, the series aluminum busbar 1, module output terminal 100, and signal acquisition harness 8 are integrated into the insulating tray 2, realizing the functions of current collection, voltage output, and status detection for multiple individual battery cells. This avoids the large space occupation inherent in existing PCB boards used for integrated busbars (CCS). Existing PCB boards can only increase signal acquisition points by widening them, which affects electrical clearance and further increases space occupation. The solution of this application avoids these defects, improving space utilization. This application solves the problem of large busbar space occupation caused by PCB boards forming integrated busbars in existing technologies.

[0049] Insulating tray 2 can be replaced with an insulating sheet.

[0050] The technical solution of this application adopts an integrated CCS busbar structure, in which the series aluminum busbar 1, the module output terminal 100 and the insulating tray 2 (blister tray or insulating sheet) are integrated, and the overcurrent busbar (including the series aluminum busbar 1 and the module output terminal 100) is fixed on the tray to improve space utilization and simplify the processing and installation process.

[0051] The signal acquisition harness 8 is used instead of the PCB board. The harness and the acquisition point terminals are crimped and then soldered onto the busbar to improve the reliability of the electrical connection and simplify the process.

[0052] The signal acquisition harness 8 is bundled with fabric tape, and the other end is connected to the BMS (Battery Management System) through a crimp terminal to realize the acquisition of voltage and temperature.

[0053] The above technical solutions reduce the space occupied inside the PACK box, improve the safety of electrical clearances, reduce costs, simplify the processing, assembly, debugging, inspection and maintenance processes, enhance the modularity, integration, versatility and practicality of the CCS structure, and improve space utilization.

[0054] The insulating tray 2 is used to fix and support the busbar (including the series aluminum busbar 1 and the module output terminal 100) while providing good electrical insulation.

[0055] The busbar (including series aluminum busbar 1 and module output terminal 100) is used for voltage and current transmission and busing. It is integrated on the tray and used for power transmission between battery cells and connection of data acquisition points.

[0056] The signal acquisition harness 8 has one end connected to the voltage and temperature acquisition points on the busbar, and the other end connected to the BMS system to realize data transmission.

[0057] The signal acquisition harness 8 is crimped and soldered to ensure the stability of the electrical connection between the acquisition harness and the busbar.

[0058] The connection between signal acquisition harness 8 and the BMS system ensures that the acquired data can be effectively utilized and monitored.

[0059] Furthermore, such as Figure 1 As shown, the multiple series-connected aluminum busbars 1 include a first aluminum busbar group 300 and a second aluminum busbar group 400. The first aluminum busbar group 300 and the second aluminum busbar group 400 are arranged opposite each other along a second direction. The first aluminum busbar group 300 is located on the first side of the insulating tray 2, and the second aluminum busbar group 400 is located on the second side of the insulating tray 2. The first aluminum busbar group 300 and the second aluminum busbar group 400 are staggered. The series-connected aluminum busbar 1 in the first aluminum busbar group 300 is used to electrically connect the poles of two adjacent battery cells close to the first side. The series-connected aluminum busbar 1 in the second aluminum busbar group 400 is used to electrically connect the poles of two adjacent battery cells close to the second side.

[0060] The reason for dividing the series aluminum busbar 1 into the first aluminum busbar group 300 and the second aluminum busbar group 400 is that each single-core cell has a positive terminal and a negative terminal, and the two terminals are arranged opposite each other, located on both sides of the insulating tray 2 along the second direction. That is to say, for any single cell, the positive terminal needs to be electrically connected to the negative terminal of the adjacent first cell, and the negative terminal needs to be electrically connected to the positive terminal of the adjacent second cell (the first and second cells are located on both sides of the cell). This is determined by the arrangement of the cells. Only in this way can the voltage of the single cell be connected in series with the voltage of the other cells to achieve the overall output.

[0061] Furthermore, the first direction is the length direction of the insulating tray 2, and / or the second direction is the width direction of the insulating tray 2.

[0062] Furthermore, the insulating tray 2 is provided with multiple aluminum busbar through holes 500, and the multiple aluminum busbar through holes 500 are arranged one-to-one with the ends of multiple series aluminum busbars 1, so that the ends of each series aluminum busbar 1 can be electrically connected to the corresponding battery cell through the aluminum busbar through holes 500.

[0063] The design of the aluminum busbar through-holes ensures precise alignment between the series aluminum busbars and the individual battery cells, avoiding the risk of unstable connections or poor contact due to positional deviations, and improving the safety and reliability of electrical connections.

[0064] By using pre-set aluminum busbar vias, the series aluminum busbars can be electrically connected to the individual battery cells quickly and accurately, greatly simplifying the battery module assembly process, improving production line efficiency, and reducing the possibility of assembly errors.

[0065] The through-hole design of the aluminum busbars can also increase the bonding strength between the series aluminum busbars and the tray, making the entire battery module more stable when subjected to vibration or impact, and extending the service life of the product.

[0066] Adding special insulating materials, such as ceramics or advanced polymers, around the aluminum busbar vias forms a protective ring, which not only enhances the insulation performance of the tray and prevents short circuit risks, but also protects the aluminum busbar from damage caused by external environmental factors (such as corrosion).

[0067] Furthermore, the signal acquisition harness 8 includes a voltage acquisition harness 6 and a temperature acquisition harness 7. One end of the voltage acquisition harness 6 is electrically connected to the series aluminum busbar 1, and the other end of the voltage acquisition harness 6 is connected to the connector 5. One end of the temperature acquisition harness 7 is electrically connected to the series aluminum busbar 1, and the other end of the temperature acquisition harness 7 is connected to the connector 5. A wiring space is provided in the middle of the insulating tray 2, and the wiring space extends along a first direction. At least a portion of the voltage acquisition harness 6 is located within the wiring space, and / or at least a portion of the temperature acquisition harness 7 is located within the wiring space.

[0068] Furthermore, a wire-passing groove is provided in the middle of the insulating tray 2, extending along the first direction to form a wiring space. This arrangement significantly improves the stability of the wire harness. It tightly integrates the wire harness with the tray, reducing external constraints, improving the overall compactness of the integrated wire harness and CCS busbar structure, and saving space.

[0069] Figure 3 The image also shows a nickel sheet 200, which is used as a soldering point for connecting other wire harnesses.

[0070] Optionally, the tray and its components can be designed as detachable modules, which facilitates flexible switching between different battery modules, as well as facilitating later maintenance and upgrades, and reducing operating costs.

[0071] Furthermore, both the voltage acquisition harness 6 and the temperature acquisition harness 7 are bound to the wiring space with tape.

[0072] Furthermore, each series aluminum busbar 1 is bonded to the insulating tray 2 with adhesive 3.

[0073] like Figure 2As shown, the module output terminal 100 includes a module positive current bus 9 and a module negative current bus 4. The module positive current bus 9 and the module negative current bus 4 are located at opposite ends of the insulating tray 2 along a first direction. Both the module positive current bus 9 and the module negative current bus 4 are connected to the insulating tray 2. The module positive current bus 9 is electrically connected to the outermost battery cell among the multiple battery cells along the first direction, and the module negative current bus 4 is electrically connected to the other outermost battery cell among the multiple battery cells along the first direction. The module positive current bus 9 and the module negative current bus 4 serve as the positive output terminal and negative output terminal of the battery cell module, respectively.

[0074] Using the technical solution of this application, the tray is made of plastic (blister tray or insulating sheet), which can provide both support and good insulation. The current bus is fixed on the tray. The wiring harness and the acquisition point terminals are crimped together, and the acquisition point terminals of the wiring harness are soldered to the current bus. The wiring harness is bundled together with cloth tape and then fixed to the tray with cable ties. The other end of the acquisition wiring harness is crimped to the terminal and connected to the BMS. During assembly, the CCS is put on the battery module, and the position, fit and flatness are checked before the current bus is soldered. The CCS is easy to process, transport and assemble, has low cost, high flexibility and strong compatibility, and achieves modularity and universality.

[0075] like Figure 4 As shown, according to one aspect of the present invention, a battery is provided, comprising a plurality of battery cell modules arranged in parallel. Figure 4 It consists of 4 battery cell modules, and the battery cell modules are as described above.

[0076] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0077] 1. High space utilization and easy to process with a diameter of 6mm. It can be integrated with the busbar using a tray (blister tray or insulating sheet) (e.g., the data collection harness is bundled together with cloth tape, and the wire harness crimped nickel terminals are soldered to the busbar).

[0078] 2. The data acquisition harness is not limited by space, and can collect both voltage and temperature data. The harness is simple to process and the technology is mature. It has good voltage resistance and insulation, fewer data acquisition problems, and low cost.

[0079] 3. It can be integrated modularly, and can be combined with various busbars and connector terminals in various ways, making it applicable to various modules or battery boxes;

[0080] 4. The busbar and the data acquisition harness are integrated into one unit, which has high integration of the mounting surface, is simple to operate, and is convenient for debugging, inspection, and maintenance.
