[0010] In one possible implementation, the transition plate further includes a second socket; the second socket is located at the end of the wiring harness storage slot away from the plug; in two adjacent transition plates along the first direction and away from the first plate, the second socket of the preceding transition plate is plugged into the plug of the following transition plate, so that the transition wiring harness and the second acquisition wiring harness of the preceding transition plate are electrically connected to the transition wiring harness of the following transition plate; the second socket of the transition plate located at the rear is used for electrical connection with the vehicle's battery management system.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0031] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0032] As the background section illustrates, in existing technologies, each battery module is equipped with a corresponding set of data acquisition harnesses, which are then connected to the battery management system (BMS) to monitor and manage each module individually. However, this wiring method results in a chaotic layout of the data acquisition harnesses within the battery pack, potentially leading to safety hazards.

[0033] To address the aforementioned technical issues, this application provides a battery pack and a vehicle. The battery pack includes a housing, battery modules, and a cover plate. The battery modules are disposed within the housing cavity of the housing. Multiple battery modules are arranged along a first direction. A cover plate is correspondingly disposed above each battery module. The cover plate includes a first plate and a transition plate. A first acquisition harness on the first plate and a second acquisition harness on the transition plate are used to electrically connect with the corresponding battery module and collect information such as temperature and voltage of the corresponding battery module. The first acquisition harness on the first board is electrically connected to the transition harness on the transition board. The ends of the transition harness and the second acquisition harness away from the first board are connected to the vehicle's battery management system. In this way, both the first and second acquisition harnesses can transmit the operating condition information of the corresponding battery modules to the battery management system. Compared with the prior art, where each battery module has a separate acquisition harness and each acquisition harness is connected to the battery management system, the battery pack provided in this application only needs to connect the second acquisition harness and the transition harness on the last transition board along the second direction and away from the first board to the battery management system to realize the transmission of operating condition information of each battery module. This is beneficial to optimizing the wiring of the acquisition harnesses inside the battery pack and ensuring the safe and stable operation of the battery pack.

[0034] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings:

[0035] It should be noted that the battery pack provided in this application embodiment can be applied to various different vehicles.

[0036] See Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the battery pack of this application embodiment is used in a vehicle and includes: a housing 300, a battery module 100 and a cover plate 200, wherein the housing 300 defines a receiving cavity; Figure 3 The X direction is the first direction, and the Y direction is the second direction. Multiple battery modules 100 can be arranged along the second direction. Within the same group, the battery modules 100 include multiple ones arranged along the first direction, and the battery modules 100 are disposed in the receiving cavity.

[0037] There are multiple cover plates 200 corresponding to battery modules 100. Among the multiple battery modules 100 in the same group, the cover plate 200 includes at least a first plate 210 and a transition plate 220 arranged along a first direction. The first plate 210 includes a first data acquisition harness, which is electrically connected to the battery module 100 connected to the first plate 210. The transition plate 220 includes a second data acquisition harness and a transition harness, which are electrically connected to the battery module 100 connected to the transition plate 220 and to the first data acquisition harness. Among the multiple groups of battery modules 100 arranged along a second direction, the cover plate 200 structures corresponding to each group are identical.

[0038] In this embodiment, when there are two battery modules 100 along the first direction, there is one transition plate 220; when there are multiple battery modules 100 along the first direction, there are two or more transition plates 220. This embodiment does not impose any limitations on this, and the selection can be made according to the actual number of battery modules 100. For example, when there is one transition plate 220, the transition harness of the transition plate 220 is electrically connected to the first acquisition harness, and the transition harness and the second acquisition harness are simultaneously electrically connected to the vehicle's battery management system. Then, the operating condition information of the two modules can be transmitted to the battery management system. When there are multiple transition plates 220 arranged along the first direction, the transition harness of the first transition plate 220 along the first direction and away from the first plate 210 is electrically connected to the first acquisition harness. In two adjacent transition plates 220, the transition harness of the latter transition plate 220 is electrically connected to the transition harness of the former transition plate 220 and the second acquisition harness. The transition harness and the second acquisition harness of the transition plate 220 located at the rear are used to be electrically connected to the vehicle's battery management system.

[0039] In this way, regardless of whether there is one or more transition boards 220, it is only necessary to connect the transition harness and the second acquisition harness on the transition board 220 at the tail end to the battery management system so that the battery management system can receive the operating condition information of each battery module 100. Compared with the prior art, where each battery module 100 is provided with an acquisition harness connected to the battery management system, the first acquisition harness and the second acquisition harness in the battery pack of this application embodiment are easier to manage, which is conducive to optimizing the layout of the harness in the battery pack, making the harness routing more reasonable, improving the safety of the battery pack, and also helps to ensure the signal transmission quality of the acquisition harness, thereby improving the accuracy and reliability of the battery management system.

[0040] It is understood that the specific number of wires in the first and second acquisition harnesses can be adjusted according to the number of cells 110 in the corresponding battery module 100 and the operating condition information to be recorded. This application embodiment does not impose any restrictions. When there are two or more transition plates 220, the number of wires in the transition harnesses of each transition plate 220 is different. The number of wires in the transition harness of the first transition plate 220 located along the first direction should be consistent with the number of wires in the first acquisition harness. The number of wires in the transition harnesses of other transition plates 220 is equal to the number of wires in the transition harnesses of the previous transition plate 220 and the second acquisition harness, so as to ensure that the operating condition information of each battery module 100 can be finally transmitted to the battery management system through the transition harnesses.

[0041] It should be noted that the first and second acquisition harnesses in this application embodiment can be acquisition harnesses for collecting operating condition information such as the temperature and low voltage of the battery pack. This application embodiment does not limit the specific type of acquisition harness, and can choose reasonably according to actual needs.

[0042] See also some of the possible implementation methods. Figures 1 to 5 As shown, the cover plate 200 of this application embodiment includes a plate body 211; the plate body 211 covers the battery module 100, and at least one wire harness storage groove 2111 is formed on the plate body 211, the wire harness storage groove 2111 extends along a first direction.

[0043] In practical implementation, the wire harness storage slot 2111 can store the first or second acquisition wire harness and the transition wire harness within the slot, avoiding potential safety hazards caused by haphazard wire harness placement and improving the neatness and maintainability of the battery pack. Simultaneously, the wire harness storage slot 2111 also protects the first, second, and transition wire harnesses, reducing their failure rate and thus improving the safety of the battery pack.

[0044] Furthermore, both the first and second acquisition harnesses are fixed within the harness storage slot 2111. The positions of the ends of each wire in the first and second acquisition harnesses are preset according to the positions of the cells 110 within the battery module 100. When assembling the battery pack, the cover plate 200 is fixed onto the battery module 100 as a whole, and each wire can automatically connect to the corresponding cell 110. This further improves the stability of the harnesses within the battery pack and optimizes the space within the battery pack. On the other hand, it is easy to operate and has a simple structure, which helps to improve the assembly efficiency of the battery pack.

[0045] See also some of the possible implementation methods. Figures 1 to 5As shown, the battery module 100 of this application embodiment includes a plurality of battery cells 110, each battery cell 110 including a tab; the cover plate 200 includes a plurality of electrode plates; the electrode plates are disposed on the plate body 211, and the tabs of two adjacent battery cells 110 are electrically connected through the electrode plates, so that the plurality of battery cells 110 are connected in series.

[0046] It is understandable that connecting the cells 110 in series with electrode plates can increase the total voltage of the battery module 100 to meet the power requirements of the vehicle. At the same time, it can ensure that each cell 110 in the battery module 100 bears the same voltage load, which helps to avoid overload or overheating of the cells 110, thereby improving the reliability and safety of the battery pack.

[0047] In addition, by placing the electrode on the plate 211 and welding the electrode to the corresponding tab, the cover plate 200 can be fixed to the battery module 100 without the need for additional fixing structures. At the same time as the cover plate 200 is fixed, the first or second acquisition harness is electrically connected to the corresponding battery module 100. Integrating the electrode, plate 211, first acquisition harness, second acquisition harness and transition harness together is beneficial to further optimize the spatial layout within the battery pack and improve the assembly efficiency of the battery pack.

[0048] See also some of the possible implementation methods. Figures 1 to 6 As shown, in this embodiment of the application, the first board 210 includes a first socket 212, and the transition board 220 includes a plug 221. The first socket 212 is disposed at one end of the wire harness storage groove 2111 of the first board 210 facing the transition board 220, and the first socket 212 is connected to the first acquisition wire harness. The plug 221 is disposed at one end of the wire harness storage groove 2111 of the transition board 220 facing the first board 210, and the plug 221 is connected to both the second acquisition wire harness and the transition wire harness. The first socket 212 is connected to the plug 221 so that the first acquisition wire harness and the transition wire harness are electrically connected.

[0049] In some embodiments, the first socket 212 is connected to a plug 221 on a transition plate 220 located near the first plate 210 along a first direction, allowing the first acquisition harness to be electrically connected to the transition harness. Simultaneously, the first acquisition harness and the second acquisition harness should be insulated from each other to avoid interference and affecting the accuracy of the signal received by the battery management system. The electrical connection between the first acquisition harness and the transition harness via the plug 221 and the first socket 212 is convenient and improves the efficiency of battery pack assembly.

[0050] See also some of the possible implementation methods. Figures 1 to 6As shown, the transition plate 220 in this embodiment of the application further includes a second socket 222; the second socket 222 is located at the end of the wire harness storage groove 2111 away from the plug 221; in two adjacent transition plates 220 along the first direction and away from the first plate 210, the second socket 222 of the preceding transition plate 220 is plugged into the plug 221 of the following transition plate 220, so that the transition wire harness and the second acquisition wire harness of the preceding transition plate 220 are electrically connected to the transition wire harness of the following transition plate 220; the second socket 222 of the transition plate 220 located at the rear is used for electrical connection with the vehicle's battery management system.

[0051] Thus, the first board 210 and the transition board 220 are connected via the first socket 212 and the plug 221. Adjacent transition boards 220 are connected via the second socket 222 of the preceding transition board and the plug 221 of the following transition board. This improves the connection efficiency between the transition boards 220. Since the number of wires in the transition harnesses on different transition boards 220 varies, the structure of the corresponding second socket 222 and plug 221 needs to be adjusted accordingly. The connection via the second socket 222 and plug 221 facilitates quick connection and disassembly. When a battery module 100 malfunctions, it can be quickly replaced, saving battery pack maintenance costs and time, and improving maintenance efficiency.

[0052] In this way, when assembling the battery pack, it is only necessary to connect the second socket 222 on the transition plate 220 at the rear to the battery management system, so that all the operating information of the battery module 100 corresponding to each cover plate 200 can be transmitted to the battery management system. This is beneficial to optimize the wiring harness layout inside the battery pack and improve the accuracy of the signal received by the battery management system.

[0053] See also some of the possible implementation methods. Figure 1 , Figure 3 and Figure 5 As shown, the battery module 100 of this application embodiment includes an explosion-proof valve, and an avoidance hole 2112 is provided on the plate 211; the avoidance hole 2112 corresponds to the explosion-proof valve, and the wire harness storage groove 2111 is staggered from the explosion-proof valve.

[0054] In practice, each battery module 100 needs to be equipped with an explosion-proof valve. When the pressure inside the battery module 100 exceeds the safety value, the explosion-proof valve will automatically open to release the pressure, which helps to ensure the stable operation of the battery pack. At the same time, when thermal runaway occurs in the battery pack, the heat inside the battery module 100 can be dissipated, reducing the risk of thermal runaway.

[0055] When the wiring harness inside the battery pack is too messy, it may obstruct the explosion-proof valve, affecting the discharge of internal gas and causing safety hazards. In this embodiment, the first acquisition wiring harness, the second acquisition wiring harness, and the transition wiring harness are fixed in the wiring harness storage groove 2111, and the wiring harness storage groove 2111 is staggered from the explosion-proof valve. An avoidance hole 2112 is also provided on the plate 211 above the explosion-proof valve to prevent other obstructions above the explosion-proof valve, thereby ensuring the normal operation of the explosion-proof valve and improving the safety and reliability of the battery pack.

[0056] See also some of the possible implementation methods. Figure 5 As shown, the plate 211 in this embodiment of the application includes a plastic component.

[0057] In some embodiments, the plate 211 is made of plastic, which has a lower density and lighter weight, which helps to reduce the overall weight of the battery pack, thereby reducing the energy consumption of the vehicle and increasing the driving range. At the same time, the plastic is a good insulating material, which can reduce the risk of short circuits in the electrical components inside the battery pack and help to improve the safety of the battery pack.

[0058] See also some of the possible implementation methods. Figure 1 , Figure 3 and Figure 5 As shown, the cover plate 200 of this application embodiment also includes a reinforcing rib 2113, which is disposed on the plate body 211.

[0059] It is understood that providing reinforcing ribs 2113 on the plate 211 can improve the structural strength and rigidity of the cover plate 200, effectively resist external impacts and vibrations, and protect the battery module 100 and other key components inside the battery pack from damage. This helps to extend the service life of the battery pack and improve the safety performance of electric vehicles. The shape and specific location of the reinforcing ribs 2113 can be set according to actual needs, and this application embodiment does not limit this.

[0060] See Figure 1 , Figure 2 and Figure 3 As shown in the embodiments of this application, a vehicle is also provided, including any of the above-described battery packs.

[0061] The structure and working principle of the battery pack have been described in detail in the above embodiments, and will not be repeated here.

[0062] In this embodiment of the application, a battery management system is provided inside the vehicle. The battery management system receives the operating status information of each battery module 100 transmitted by the first acquisition harness and the second acquisition harness, thereby monitoring, controlling and managing the operating status of each battery module 100, and ensuring that the battery pack can work under safe, efficient and reliable conditions.

[0063] In summary, when assembling the battery pack provided in this application embodiment, the battery modules 100 are first fixed in an array sequentially within the receiving cavity of the housing. Then, a cover plate 200 is provided on each battery module 100. The electrode plates on the cover plate 200 are welded to the tabs of the cells 110 within the battery module 100, thereby fixing the cover plate 200 to the battery module 100. Simultaneously, the cells 110 are connected in series. At this time, the first and second acquisition harnesses are electrically connected to their respective battery modules 100. Next, the first socket 212 or the second socket 222 is inserted into the plug 221 to connect the multiple cover plates 200 arranged along the first direction. Finally, the second socket 222 on the transition plate 220 located at the tail end of the first direction is connected... 22 is electrically connected to the vehicle's battery management system, thereby enabling the assembly of the battery pack and connecting each battery module 100 within the battery pack to the battery management system for monitoring and management. Compared to the prior art, where each battery module 100 has its own data acquisition harness, and each data acquisition harness is independently configured and connected to the battery management system, in this embodiment, the transition harness, the first data acquisition harness, and the second data acquisition harness are all located within the harness storage slot 2111. Furthermore, monitoring of all battery modules 100 can be achieved by electrically connecting only one plug 221 to the battery management system. This facilitates the optimization of the harness layout within the battery pack while ensuring the accuracy of the signals received by the battery management system, thereby improving the safety and reliability of the battery pack.
