[0037] In the description of the embodiments of this application, unless otherwise expressly specified and limited, the technical terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

"Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0039] To facilitate the installation and removal of domain controller battery packs, thereby saving time and improving maintenance convenience, a domain controller battery pack is proposed, such as... Figure 1 and Figure 2 As shown, the domain-controlled battery pack includes a battery assembly 1 and a domain-controlled assembly 2. The battery assembly 1 includes a battery box 11 and a cell assembly 14. The battery box 11 is arranged as shown in the figure. Figure 3 The cavity 12 shown is in which the battery cell assembly 14 is disposed. The battery box 11 has a connection opening 13 that communicates with the cavity 12. The domain control assembly 2 includes a mounting carrier 21 and multiple domain control modules 22. The multiple domain control modules 22 are all connected to the mounting carrier 21. The mounting carrier 21 is detachably connected to the outer wall of the battery box 11.

[0040] Although Figure 1 and Figure 2 The domain control component 2 shown is only located on one side of the battery assembly 1, but it is understood that the domain control component 2 can be located on both sides or more sides of the battery assembly 1 to match vehicle layout requirements. For example, the domain control component 2 can be arranged on both sides of the battery assembly 1 along the length direction, and / or, the domain control component 2 can be arranged on both sides of the battery assembly 1 along the width direction.

[0041] Battery assembly 1 may be a component structure including batteries, which can provide electrical energy as a power source. The battery box 11 in battery assembly 1 may be a box structure for accommodating battery cell assembly 14, forming a receiving cavity 12. The battery cell assembly 14 is disposed in the receiving cavity 12 and protected by the battery box 11. In some embodiments, a connection opening 13 is provided on the wall of the battery box 11, communicating with the receiving cavity 12. This allows at least a portion of the domain control component 2 to extend into the receiving cavity 12 of the battery box 11 through the connection opening 13 when connected to the wall of the battery box 11, thus embedding the domain control component 2 into the battery box 11 and improving the robustness of the connection between the domain control component 2 and the battery assembly 1.

[0042] like Figure 4 As shown, the domain controller component 2 can be a component including multiple domain controller modules 22. The mounting carrier 21 of the domain controller component 2 can be a structure for connecting the multiple domain controller modules 22 thereon, and for supporting the multiple domain controller modules 22. By connecting the multiple domain controller modules 22 to the mounting carrier 21, and connecting the mounting carrier 21 to the outer wall of the battery box 11, the multiple domain controller modules 22 can be connected to the mounting carrier 21 as a whole structure on the wall of the battery box 11 for easy assembly and disassembly, which improves the convenience of assembly and disassembly.

[0043] In some embodiments, the mounting carrier 21 can be a plate-like structure, a block-like structure, or an eggshell-like cover 212 structure. Multiple domain control modules 22 are connected to the mounting carrier 21. The mounting carrier 21 is connected to the wall of the battery box 11 and has a connection opening 13, so that the mounting carrier 21 can cover the connection opening 13, which helps to improve the sealing of the domain control battery pack.

[0044] Specifically, the detachable connection of the mounting carrier 21 to the outer wall of the battery box 11 can be achieved by bolts, snap-fit ​​connections, or by the interlocking of slide rails and grooves. Those skilled in the art can design the connection method between the mounting carrier 21 and the wall of the battery box 11 according to actual conditions.

[0045] The wiring harness can be used for electrical connection between the devices in the domain control component 2 and the battery cell assembly 14. It can include communication wiring harnesses for communication connection between the devices in the domain control component 2 and the battery cell assembly 14, and can also include power transmission wiring harnesses for power transfer between the devices in the domain control component 2 and the battery cell assembly 14. The communication connection between the devices in the domain control component 2 and the battery cell assembly 14 can be established through a communication module. The communication module collects information from the battery cell assembly 14 via a circuit board and transmits this information to the functional devices in the domain control component 2 via the communication wiring harness.

[0046] In the above structure, the domain control module 22 is connected to the mounting carrier 21, which is detachably connected to the outer wall of the battery box 11. This allows the domain control module 22 to be easily installed and removed from the outer wall of the battery box 11, enabling the domain control module 22 to be removed and disassembled separately from the domain control battery pack, thus improving the convenience of maintenance.

[0047] In some embodiments, the mounting carrier 21 includes a mounting plate 211, a plurality of domain control modules 22 are connected to the mounting plate 211, and the mounting plate 211 is detachably connected to the outer wall of the battery box 11 and covers the connection opening 13.

[0048] Mounting plate 211 can be a plate-shaped component, serving as the main structure on mounting carrier 21 to support multiple domain control modules 22. These modules are connected to the mounting plate 211 for centralized placement within the domain control assembly 2. By detachably connecting the mounting plate 211 to the outer wall of the battery box 11 and covering the connection opening 13, the mounting plate 211 can not only centrally house the multiple domain control modules 22 but also act as a sealant for the connection opening 13, ensuring the airtightness of the receiving cavity 12 within the battery assembly 1. Because the plate-shaped component has a large surface area, connecting multiple domain control modules 22 to the plate-shaped mounting plate 211 allows for the placement of a larger number of domain control modules 22 on the mounting plate 211.

[0049] In some embodiments, the mounting plate 211 includes a first wall 2111 and a second wall 2112 disposed at relative intervals, the second wall 2112 being disposed toward the receiving cavity 12, at least a portion of the plurality of domain control modules 22 being connected to the first wall 2111, and the remaining domain control modules 22 being connected to the second wall 2112 and extending into the receiving cavity 12 from the connection opening 13.

[0050] The first wall surface 2111 and the second wall surface 2112 can refer to two walls that are relatively spaced apart on the mounting plate 211. The material between the first wall surface 2111 and the second wall surface 2112 is the material of the mounting plate 211. The second wall surface 2112 is the wall surface facing the receiving cavity 12, and the first wall surface 2111 is the wall surface facing away from the receiving cavity 12.

[0051] In some embodiments, at least a portion of the multiple domain control modules 22 are connected to the first wall 2111, and the remaining domain control modules 22 are connected to the second wall 2112, such that some of the multiple domain control modules 22 are located on the outside of the mounting plate 211, while the remaining domain control modules 22 are located on the inside of the mounting plate 211, so that the multiple domain control modules 22 are respectively arranged on both sides of the mounting plate 211, which facilitates the arrangement of the multiple domain control modules 22 on the mounting plate 211.

[0052] In some embodiments, the domain control module 22 connected to the second wall 2112 extends into the receiving cavity 12 from the connection opening 13, so that a portion of the multiple domain control modules 22 can be located in the receiving cavity 12, so as to utilize the remaining space gap after the discharge core assembly 14 is placed in the receiving cavity 12, which is beneficial to improve the space utilization of the receiving cavity 12.

[0053] In some embodiments, the mounting carrier 21 further includes a cover 212, which is connected to the mounting plate 211 and covers the domain control module 22 connected to the first wall surface 2111.

[0054] The housing 212 can be a shell structure used to cover the domain control module 22 and protect it. By connecting the housing 212 to the first wall surface 2111 of the mounting plate 211, the housing 212 covers the domain control module 22 disposed on the first wall surface 2111, thereby protecting the domain control module 22 and reducing the possibility of damage such as bumps and rain to the domain control module 22 connected to the first wall surface 2111 of the mounting plate 211.

[0055] In some embodiments, such as Figure 5 As shown, a cavity 21112 is formed on the first wall surface 2111 of the mounting plate 211. The domain control module 22, connected to the first wall surface 2111, is located in the cavity 21112. By placing the domain control module 22 in the cavity 21112, the mounting plate 211 can protect the domain control module 22. Exemplarily, a surrounding wall 21111 is provided on the first wall surface 2111 of the mounting plate 211, forming the cavity 21112. A cover 212 is connected to the surrounding wall 21111 and seals the opening of the cavity 21112, thus protecting the domain control module 22 in the cavity 21112 and reducing the possibility of damage from impacts, rain, etc. In some embodiments, such as... Figure 6 As shown, a boss 213 is provided on the second wall surface 2112 of the mounting plate 211. The boss 213 forms a stepped surface on the second wall surface 2112. The boss 213 extends into the receiving cavity 12 from the connecting opening 13. The outer peripheral surface 2132 of the boss 213 is used to cooperate with the connecting opening 13.

[0056] The boss 213 can be a structure protruding from the second wall surface 2112 of the mounting plate 211. The outer peripheral surface 2132 of the boss 213 can refer to the surface surrounding the outer periphery of the boss 213. By engaging the outer peripheral surface 2132 with the connecting opening 13, the mounting plate 211 can further seal the connecting opening 13, thereby improving the sealing performance of the receiving cavity 12 and preventing water from entering the receiving cavity 12 through the connecting opening 13. The boss 213 not only improves the overall structural strength of the mounting plate 211 but also extends into the receiving cavity 12 from the connecting opening 13, facilitating the connection of the mounting carrier 21 at the connecting opening 13.

[0057] In some embodiments, the plurality of domain control modules 22 include a battery management unit 221, a battery energy distribution unit 222, a power conversion module 223, and an on-board charging module 224. The battery management unit 221 is connected to a first wall 2111, and the battery energy distribution unit 222, the power conversion module 223, and the on-board charging module 224 are connected to a second wall 2112 and extend into the receiving cavity 12 from the connection opening 13.

[0058] The battery management unit 221 can perform functions such as data acquisition, control, protection, communication, power calculation, signal transmission, and power transmission for the cells in the cell assembly 14. It can intelligently manage and maintain multiple cells, which is beneficial to improving the performance and service life of the cell assembly 14. In some embodiments, the battery management unit 221 may also include a vehicle controller 2211 and a motor controller 2212, so that the battery management unit 221 can not only control the drive motor to work according to the set direction, speed, angle, and response time, but also manage the battery system, electric drive system, thermal management system, etc., specifically including the control of gear position, accelerator pedal, brake pedal, torque control calculated according to the real-time power battery charge, and control of low-voltage and high-voltage power supply and energy recovery of the whole vehicle.

[0059] Since the battery management unit 221 and the cell assembly 14 are mainly connected via a communication harness, and the power conversion module 223 and the on-board charging module 224 are mainly connected to the cell assembly 14 via a power transmission harness, connecting the power conversion module 223 and the on-board charging module 224 to the second wall 2112 and extending them into the receiving cavity 12 through the connection opening 13 can reduce the amount of power transmission harness used, which is beneficial to reducing the cost of the domain-controlled battery pack.

[0060] In some embodiments, such as Figure 7 As shown, the domain-controlled battery pack also includes an external connector 23, which is disposed on the first wall surface of the mounting plate.

[0061] The external connector 23 can be a plug-in component used by the domain control battery pack to electrically connect with external devices. The domain control module 22 in the domain control battery pack can be easily connected to and quickly disconnected from the wiring harness of external devices via the external connector 23. By setting the external connector 23 on the first wall surface 2111 of the mounting plate 211, the external connector 23 can be fixed in position relative to the domain control module 22 on the mounting plate 211. This not only ensures the robust connection between the external connector 23 and the domain control module 22, but also allows the mounting plate 211 to provide good support for the external connector 23, making it easy to plug and unplug the external connector 23. Some of the external connectors 23 are used for communication between the domain control battery pack and the outside world, such as communication with the vehicle interface; others are used for power output or input between the domain control battery pack and the outside world, such as connecting to the battery energy distribution unit via conductive components. For example, the external connector 23 may include a connector for external connection to the power conversion module, a three-phase output connector for the battery assembly 1, a fast charging connector for the battery assembly 1, an upper-mount / slow charging connector for the battery assembly 1, and a thermistor / air conditioning connector for regulating the internal ambient temperature of the housing cavity 12.

[0062] In some embodiments, the boss 213 has a recess 2131, and at least a portion of the domain control module 22 is located in the recess 2131.

[0063] The recess 2131 can be a spatial structure on the wall surface of the boss 213 away from the first wall surface 2111, which can be formed by removing material through milling or other methods. By placing at least a portion of the domain control module 22 in the recess 2131, the space here can be utilized, reducing the space occupied by the domain control component 2 in the receiving cavity 12, which is beneficial for installing more battery cells in the receiving cavity 12 and helps to improve the energy density of the battery assembly 1.

[0064] In some embodiments, the battery box 11 includes a first box body 111 and a second box body 112, which are fastened together to form a receiving cavity 12, and a connecting opening 13 is formed in the wall of the second box body 112.

[0065] The first housing 111 and the second housing 112 can be partial housings that make up the whole of the battery box 11. Both have a cavity structure inside. After the first housing 111 and the second housing 112 are fastened together, the cavity structure forms a receiving cavity 12 for accommodating the battery cell assembly 14. By opening the connection opening 13 on the wall of the first housing 111 or the second housing 112, and avoiding the connection opening 13 being located at the connection structure between the first housing 111 and the second housing 112, it is beneficial to improve the firmness of the connection between the first housing 111 and the second housing 112.

[0066] In some embodiments, the wall of the first housing 111 is provided with a recess, and the wall of the second housing 112 is provided with a protrusion. The protrusion protrudes from the second housing relative to the first housing, and the protrusion and the recess are aligned. The connecting opening 13 is opened on the wall of the second housing 112 provided with the protrusion.

[0067] By providing a protrusion on the second housing that protrudes relative to the first housing, the size of the protrusion on the second housing 112 can be increased, so that the connection opening 13 on the wall of the protrusion of the second housing 112 has sufficient size to meet the requirements of mating with the mounting carrier 21. In addition, the protrusion can also improve the structural strength of the wall of the second housing where the connection opening 13 is located, which helps to extend the service life of the domain-controlled battery pack.

[0068] Specifically, the wall of the first housing 111 is provided with a recess that is aligned with the protrusion, so that the first housing 111 and the second housing 112 can be engaged to achieve a snap-fit.

[0069] In some embodiments, the first housing 111 is provided with a first sealing edge, and the second housing 112 is provided with a second sealing edge, with the first sealing edge connected to the second sealing edge.

[0070] By connecting the first sealing edge and the second sealing edge, the first housing 111 and the second housing 112 can be fastened together, which can improve the sealing performance of the connection between the first housing 111 and the second housing 112 and improve the waterproof performance of the domain-controlled battery pack.

[0071] In some embodiments, the mounting carrier 21 is provided with a connecting structure, and the mounting carrier 21 can be connected to the outer wall of the battery box 11 through the connecting structure.

[0072] The connection structure can be a structure that allows the mounting carrier 21 to be detachably connected to the outer wall of the battery box 11. It can be a bolt assembly, a snap-fit ​​structure, or a plug-in structure, so that the mounting carrier 21 can be detachably connected to the outer wall of the battery box 11.

[0073] In some embodiments, the connection structure includes bolts, the mounting carrier 21 has a connection hole, the outer wall of the battery box 11 has a threaded hole, and the bolt passes through the connection hole and is screwed into the threaded hole.

[0074] The connection hole can be a through hole structure set on the mounting carrier 21, which is set perpendicular to the direction in which the boss 213 on the mounting carrier 21 is inserted into the connection opening 13. The bolt passes through the connection hole and is screwed into the threaded hole, which can fasten the mounting carrier 21 to the outer wall of the battery box 11 along the direction in which the boss 213 is inserted into the connection opening 13.

[0075] In some embodiments, the domain control module 22 includes at least one of a battery management unit 221, a circuit breaker unit, a battery energy distribution unit, a power conversion module 223, an on-board charging module, a vehicle control unit, a motor control unit, a vehicle stability system, a drive system control unit, a driving system control unit, a steering control unit, and a comfort system management unit.
