[0029] In the field of power battery technology, the battery pack, as a core component for energy storage and supply, is crucial for its performance and safety. The BMS (Battery Management System), the nerve center of the battery pack, directly impacts the battery pack's service life and operational reliability through real-time monitoring of battery status, balancing control, and safety protection. Existing battery management system architectures typically include a main controller and a slave controller. The slave controller is primarily responsible for collecting parameters such as the battery module's voltage and temperature and transmitting this data to the main controller for centralized management. As battery pack capacity and power requirements increase, the number of battery cells continues to increase, and accordingly, the number of slave controllers also increases. Wiring harnesses are typically required to achieve electrical connections and data communication between the slave controllers and the battery modules, between the slave controllers, and between the slave controllers and the main controller. When there are a large number of slave controllers, the aggregation and layout of the wiring harnesses often present challenges. Therefore, optimizing the connection layout of the slave controllers in a battery management system to address the series of problems caused by the centralized wiring harness is a technical problem that urgently needs to be addressed by those skilled in the art.

[0030] In response to the problems existing in the above-mentioned related technologies, the present invention provides a solid-state battery pack 10, a solid-state battery 100 and a vehicle 100, by arranging multiple battery assemblies along a first direction, and setting the slave board controller corresponding to the battery assembly at its end along the second direction, and the two slave board controllers corresponding to the two adjacent battery assemblies are respectively set at the opposite ends of the two battery assemblies along the second direction, and the first direction is perpendicular to the second direction, so that each slave board controller can occupy the spatial position at the same end of the two battery assemblies, which is convenient for the arrangement of the slave board controllers, reduces the wiring density around the slave board controllers, reduces the difficulty of wiring, and at the same time makes the wiring harnesses converge at both ends of the second direction, reduces the crossing of wiring harnesses across directions, and improves the cleanliness of the internal space and the convenience of wiring harness management.

[0031] The following describes it in detail with reference to specific embodiments.

[0032] Combine Figures 1 to 3 As shown, an embodiment of the present invention provides a solid-state battery pack 10, including a battery management system and a plurality of battery assemblies 30; the battery assembly 30 includes at least one battery module 40; the battery management system includes a plurality of slave board controllers 22, and the plurality of slave board controllers 22 are connected one-to-one with the plurality of battery assemblies 30; wherein, the plurality of battery assemblies 30 are arranged along a first direction, and the two slave board controllers 22 corresponding to two adjacent battery assemblies 30 are respectively arranged at opposite ends of the two battery assemblies 30 along a second direction, and the first direction is perpendicular to the second direction.

[0033] In this embodiment, each battery module 40 includes a plurality of battery cells, each battery assembly 30 includes at least one battery module 40, and each slave board controller 22 is used to collect parameters such as the voltage and temperature of the battery cells in the battery assembly 30 to which it is connected. The solid-state battery pack 10 includes a plurality of battery assemblies 30, and the plurality of battery assemblies 30 are arranged along the first direction, that is, the end of each battery assembly 30 along the second direction is close to the end of the solid-state battery pack 10 along the second direction. The slave board controller 22 corresponding to the battery assembly 30 is set at its end along the second direction, which can shorten the length of the connection harness between the battery assembly 30 and its corresponding slave board controller 22, and make the slave board controller 22 located at the end of the solid-state battery pack for easy arrangement; moreover, in this embodiment, the slave board controllers 22 of adjacent battery assemblies 30 are respectively set at the opposite ends of the two battery assemblies 30 along the second direction, so that each The slave board controller 22 can occupy the spatial position at the same end of the two battery assemblies 30, reducing the wiring density around the slave board controller, reducing the wiring difficulty, and facilitating the arrangement of the slave board controller 22; in addition, the slave board controller 22 is respectively arranged at the opposite ends of the two battery assemblies 30 along the second direction, forming a spatial vertical distribution relationship with the arrangement of the battery assemblies 30 along the first direction, avoiding the spatial conflict between the slave board controller 22 and the battery assembly 30 in the same direction, and further optimizing the internal layout of the solid-state battery pack 10; at the same time, the wiring harnesses are gathered at both ends of the second direction, reducing the crossing of wiring harnesses across directions, and improving the cleanliness of the internal space and the convenience of wiring harness management.

[0034] It is understandable that, please refer to Figure 1 、 Figure 2 The first direction can be the extension direction of the Y-axis, which is the longitudinal direction. The positive direction of the Y-axis represents the front, and the reverse direction of the Y-axis represents the rear. The second direction can be the extension direction of the X-axis, which is the transverse direction. The positive direction of the X-axis represents the right, and the reverse direction of the X-axis represents the left. Multiple battery assemblies 30 are arranged in an orderly manner along the same direction to achieve large-scale expansion of the solid-state battery pack 10 and meet different capacity requirements. At the same time, the standardized arrangement method facilitates automated assembly and subsequent maintenance. By arranging the two slave board controllers 22 corresponding to the two adjacent battery assemblies 30 at the opposite ends of the solid-state battery pack 10, the wiring harnesses corresponding to the two adjacent battery assemblies 30 can be respectively gathered to the two ends of the solid-state battery pack 10 along the second direction, and all the slave board controllers 22 can be evenly distributed at the opposite ends of the solid-state battery pack 10, making full use of the spatial layout, reducing wiring harness accumulation, and improving the overall layout rationality of the solid-state battery pack 10. In addition, the dispersed layout of the slave board controllers 22 can also simplify the wiring harness direction, reduce assembly difficulty, and improve production efficiency and long-term reliability. At the same time, the decentralized layout of the board controller 22 also facilitates fault diagnosis and maintenance, reduces potential failure points caused by concentrated wiring harnesses, and further improves the stability and safety of the system.

[0035] Specifically, the battery management system further includes a mainboard controller 21 , and the plurality of slave board controllers 22 are electrically connected to the mainboard controller 21 .

[0036] Specifically, see Figure 1 、 Figure 2 The solid-state battery pack 10 includes a first battery assembly 301, a second battery assembly 302, a third battery assembly, and a fourth battery assembly arranged in sequence along a first direction; the battery management system may include a first slave board controller 221, a second slave board controller 222, a third slave board controller, and a fourth slave board controller. The first battery assembly 301 is connected to the first slave board controller 221, the second battery assembly 302 is connected to the second slave board controller 222, and so on. The first slave board controller 221 corresponding to the first battery assembly 301 and the second slave board controller 222 corresponding to the second battery assembly 302 are arranged along the second direction; the first slave board controller 221 can fully utilize the spatial position at the left end of the first battery assembly 301 and the second battery assembly 302, and the second slave board controller 222 can fully utilize the spatial position at the right end of the first battery assembly 301 and the second battery assembly 302, thereby facilitating the arrangement of the first slave board controller 221 and the second slave board controller 222, as well as the arrangement of related wiring harnesses.

[0037] In some embodiments, please refer to Figure 1 、 Figure 2 The battery assembly 30 includes four battery modules 40 arranged in an array along the first direction and the second direction; wherein the four battery modules 40 are electrically connected in sequence along the second direction, the first direction, and the second direction.

[0038] It is understandable that, please refer to Figure 1 、 Figure 2 The four battery modules 40 are electrically connected in sequence along the second direction, the first direction, and the second direction, that is, the four battery modules 40 are connected in series in sequence along a serpentine connection path. In this way, the connection path of each battery module 40 can be made more uniform, thereby improving the overall performance and life of the solid-state battery pack 10. Moreover, the four modules are connected in series along the second direction, the first direction, and the second direction, so that the two battery modules 40 at the head and tail ends of the series circuit can be close to the two ends of the battery assembly 30 along the first direction, respectively, so as to facilitate series connection with the battery modules 40 of the two adjacent battery assemblies 30.

[0039] Specifically, see Figure 1 、 Figure 2The battery assembly 30 may include a first battery module 401, a second battery module 402, a third battery module 403, and a fourth battery module 404. The first battery module 401, the second battery module 402, the third battery module 403, and the fourth battery module 404 are electrically connected in sequence in a serpentine connection path. The first battery module 401 and the fourth battery module 404 may also be electrically connected to the battery modules in the two battery assemblies adjacent to each other in front and behind the battery assembly 30, respectively, to achieve series connection between the battery assemblies. For example, the first battery module 401 of the second battery assembly 302 is electrically connected to the fourth battery module 404 of the first battery assembly 301.

[0040] In some embodiments, please refer to Figure 2 The battery module 40 includes a data acquisition port 23, and the data acquisition port 23 of each battery module 40 is connected to the corresponding slave board controller 22; wherein, the data acquisition ports 23 of the two battery modules 40 close to the corresponding slave board controller 22 are arranged at the end of the battery module 40 close to the corresponding slave board controller 22; the data acquisition ports 23 of the two battery modules 40 away from the corresponding slave board controller 22 are arranged at the end of the battery module 40 away from the corresponding slave board controller 22.

[0041] like Figure 2 As shown, taking the first battery assembly 301 as an example, the two battery modules 40 located closest to their corresponding slave controllers 22 (first slave controller 221) in the first battery assembly 301 are the first battery module 401 and the fourth battery module 404. This means that the data acquisition ports 23 of the first and fourth battery modules 401 and 404 are located at the ends closest to their corresponding slave controllers 22 (first slave controller 221). In the first battery assembly 301, the two battery modules 40 located further away from their corresponding slave controllers 22 (first slave controller 221) are the second and third battery modules 402 and 403. This means that the data acquisition ports 23 of the second and third battery modules 402 and 403 are located at the ends further away from their corresponding slave controllers 22 (first slave controller 221). In this way, the data acquisition ports 23 of the four battery modules 40 are located at both ends of the battery assembly 30 along the second direction, facilitating connection to the wiring harness.

[0042] The data acquisition port 23 is connected to the slave controller 22 to enable real-time monitoring of battery cell performance (such as voltage and temperature), providing accurate data support for battery status assessment and safety protection, and improving the timeliness and accuracy of management. In this embodiment, the data acquisition port 23 of each battery module 40 is optimally arranged relative to the slave controller 22. This avoids positioning the data acquisition port 23 near the center of the battery assembly 30 and prevents the connection harness 24 connecting the data acquisition port 23 from passing through the interior of the battery assembly 30. This reduces signal transmission interference, improves data acquisition accuracy, and makes the harness layout more orderly.

[0043] In some embodiments, please refer to Figure 2 The battery management system also includes a connecting harness 24 connecting the data acquisition port 23 and the slave board controller 22; wherein, the connecting harness 24 corresponding to the two battery modules 40 away from the slave board controller 22 is electrically connected to the slave board controller 22 by passing around the periphery of the battery assembly 30.

[0044] The connecting harness 24 provides a physical channel for data transmission, ensuring signal communication between the acquisition unit and the slave controller 22, thus ensuring the monitoring function is implemented. The connecting harness 24 is routed around the periphery of the battery assembly 30, that is, the connecting harness 24 does not pass through the interior of the battery assembly 30, avoiding occupying the core space within the battery assembly 30 and making the internal layout neater. It also reduces cross-entanglement of the harness, reduces electromagnetic interference, and improves signal transmission stability. It also facilitates harness organization and subsequent maintenance.

[0045] In some embodiments, please refer to Figure 2 The battery module 40 includes two module electrodes 41 with opposite polarities; the two module electrodes 41 are respectively arranged at the diagonal parts of the top surface of the battery module 40; wherein, the two module electrodes 41 corresponding to the two battery modules 40 arranged in the second direction are arranged adjacent to each other, the two module electrodes 41 corresponding to the two battery modules 40 arranged in the first direction are arranged far away from each other, and the two module electrodes 41 corresponding to the two adjacent battery assemblies 30 are arranged adjacent to each other.

[0046] It is understandable that, please refer to Figure 2The module electrode 41 with a “+” sign represents a positive module electrode, and the module electrode 41 with a “-” sign represents a negative module electrode. The positive module electrode and the negative module electrode of each battery module 40 are correspondingly arranged at the diagonal corners of the top surface of the battery module 40; the two module electrodes 41 correspondingly connected to the two battery modules 40 arranged in the second direction are arranged adjacent to each other, for example, the negative module electrode of the first battery module 401 and the positive module electrode of the second battery module 402 are arranged at relatively close corners, and the negative module electrode of the third battery module 403 and the positive module electrode of the fourth battery module 404 are arranged at relatively close corners; the two module electrodes 41 correspondingly connected to the two battery modules 40 arranged in the first direction are arranged far away from each other, for example, the second battery module 402 The negative module electrode of the battery assembly 30 and the positive module electrode of the third battery module 403 are arranged at relatively far corners; in this embodiment, the four battery modules 40 of the battery assembly 30 form an arrangement period, and the arrangement of the module electrodes 41 in the battery assembly 30 can not only facilitate the series connection between the battery modules 40 inside the battery assembly 30, but also realize the adjacent arrangement of the two module electrodes 41 corresponding to the connection of the two adjacent battery assemblies 30. For example, the positive module electrode of the first battery module 401 of the second battery assembly 302 and the negative module electrode of the fourth battery module 404 of the first battery assembly 301 are arranged at relatively close corners, which is convenient for connection between the two, thereby reducing the length of the electrical connector between the two adjacent battery assemblies 30, reducing conductive loss and resistive heating, and reducing material costs.

[0047] Specifically, the polarities of the two module electrodes 41 of the two adjacently connected battery modules 40 are opposite.

[0048] In some embodiments, please refer to Figure 2 The battery assembly 30 further includes a first conductive connector 31, and two adjacent battery assemblies 30 are electrically connected via the first conductive connector 31; wherein the first conductive connector 31 is provided at the end of the battery assembly 30 along the second direction.

[0049] For example Figure 2 As shown, the positive module electrode of the first battery module 401 of the second battery assembly 302 and the negative module electrode of the fourth battery module 404 of the first battery assembly 301 are electrically connected through the first connector 31. The first electrical connector is arranged at the end of the battery assembly 30, not in the middle of the battery assembly 30. The space at the end of the battery assembly 30 is larger, which facilitates the assembly operation of the first conductive connector 31.

[0050] Specifically, the battery assembly 30 further includes a second conductive connector 32, which is used to connect the two battery modules 40, for example Figure 2As shown, in the second battery assembly 302 , the first battery module 401 is electrically connected to the second battery module 402 via the transversely arranged second conductive connector 32 , and the second battery module 402 is electrically connected to the third battery module 403 via the longitudinally arranged second conductive connector 32 .

[0051] In some embodiments, please refer to Figure 3 The solid-state battery pack 10 also includes a plurality of insulating cover plates 13 provided on the plurality of battery assemblies 30, and the plurality of battery assemblies 30 correspond one to one with the plurality of insulating cover plates 13. The insulating cover plates 13 can prevent the electrical connectors on the battery assembly 30 from being accidentally touched by the assembler, thereby reducing the risk of electric shock for the assembler; it can also prevent external foreign matter, especially conductive foreign matter, from entering the interior of the battery assembly 30. At the same time, the insulating cover plates 13 can also have a certain heat insulation effect, reducing the heating of the battery module by external heat, thereby improving the safety and reliability of the battery assembly 30. In addition, when the battery assembly 30 is overheated or abnormal, the heat generated causes the air to expand. The hot air needs to push open the insulating cover plates 13, thereby quickly releasing the internal pressure and preventing the solid-state battery pack 10 from exploding as a whole. Compared with the design in which one insulating cover plate 13 covers multiple battery assemblies 30, in this embodiment, the hot gas is more easily dispersed and discharged through the gaps between the multiple insulating cover plates 13, further improving the safety performance of the solid-state battery pack 10.

[0052] Specifically, the material of the insulating cover plate 13 can be polycarbonate, polyethylene terephthalate, ceramic silicone tape, mica paper, etc., which is only used as an example and is not specifically limited.

[0053] In some embodiments, the solid-state battery pack 10 further includes an adhesive layer disposed between the battery assembly 30 and the insulating cover 13 to adhere the insulating cover 13 to the battery assembly 30. Specifically, the material of the adhesive layer can be double-sided tape, etc., which is only used as an example and is not specifically limited here. The adhesive force of the adhesive layer should not be too strong. When the battery assembly 30 is overheated or abnormal, the heat generated causes the air to expand. The hot air can push open the insulating cover 13, thereby quickly releasing the internal pressure.

[0054] In some embodiments, see Figure 3 The solid-state battery pack 10 further includes an outer shell and a buffer layer 14 disposed between the outer shell and the insulating cover 13. For ease of understanding, the outer shell is not shown. The buffer layer 14 can be made of an elastic material, such as a foam material, to effectively absorb vibration and impact, thereby protecting the battery assembly 30 from mechanical damage.

[0055] Specifically, see Figure 3 The buffer layer 14 may include a plurality of buffer blocks arranged at intervals.

[0056] In some embodiments, please refer to Figure 1 、 Figure 2 The solid-state battery pack 10 also includes a main controller 11 and a power output component 12 connected to the main controller 11; wherein, the power output component 12 extends along the second direction, and the same number of battery assemblies 30 are respectively arranged on both sides of the power output component 12.

[0057] Specifically, see Figure 1 、 Figure 2 The motherboard controller 21 can be integrated into the main controller 11. The main controller 11 coordinates power output management, and the power output element 12 serves as an external energy interface, ensuring stable power transmission between the solid-state battery pack 10 and external devices. The power output element 12 is designed to be oriented perpendicular to the arrangement of the battery components 30, optimizing the internal space allocation of the solid-state battery pack 10, avoiding conflicts with the component layout, and improving the overall compactness of the structure. The battery components 30 are symmetrically distributed on both sides of the output element, balancing the weight and current load of the solid-state battery pack 10, reducing losses and overheating risks caused by localized stress or current concentration, and improving operational safety.

[0058] For example Figure 3 As shown, two battery assemblies, the first battery assembly 301 and the second battery assembly 302, are provided on one side of the power output member 12 along the first direction, and two battery assemblies, the third battery assembly and the fourth battery assembly, are provided on the other side of the power output member 12 along the first direction.

[0059] Combine Figure 4 As shown, the embodiment of the present invention further provides a vehicle 100, comprising the solid-state battery pack 10 as described above. The beneficial effects of the vehicle of this embodiment are the same as those of the solid-state battery pack described above, and will not be repeated here.

[0060] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the protection scope of the present invention.
