In this way, the side space of the box can be utilized instead of the height space, which is more suitable for the layout requirements of vehicles that are sensitive to thickness.

[0032] In addition, by covering the electrical components with the casing, the components are prevented from being directly exposed to the external environment, thus improving the protection of the electrical components.

[0053] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, 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.

[0054] As a key component of new energy vehicles, the power supply control device is responsible for distributing the high-voltage electrical energy of the battery pack to high-voltage electrical equipment such as the motor assembly controller, drive motor assembly and electric air conditioning compressor, and safely directing the current to the battery pack during charging.

[0055] However, in related technologies, the power supply control device is usually located on the top cover of the battery pack housing, which can easily lead to a large overall thickness of the battery pack.

[0056] To address or improve the problem that power supply control devices often result in a large overall thickness of the battery pack, this utility model provides a power supply control device, a battery pack, and a carrier.

[0057] The following is combined with Figures 1 to 14 The diagram illustrates a power supply control device provided in an embodiment of the present invention.

[0058] Specifically, the power supply control device includes a housing 1, a mounting base 2, electrical components 3, a charging connector 4, and a discharging connector 5.

[0059] The outer casing 1 has a connecting part for connecting to the outer side wall of the battery pack. It is understood that the outer side wall refers to the circumferential or vertical side wall of the casing when the top cover is facing upwards. Optionally, the connecting part is screwed, glued, or welded to the casing. The end of the outer casing 1 facing the battery pack has an opening 101, which allows the mounting base 2 and electrical components 3 to pass through.

[0060] Mounting base 2 is installed inside the housing 1. For example, mounting base 2 can be glued, welded or screwed to housing 1.

[0061] Electrical component 3 is mounted on mounting base 2, for example, by bonding, welding, or screwing. It is understood that electrical component 3 forms part of charging / discharging circuit 20 and is used for electrical connection to the battery within the battery pack. Electrical component 3 can be a relay or fuse 305.

[0062] At least a portion of the charging connector 4 is located on the outer wall of the housing 1. The charging connector 4 is electrically connected to the electrical component 3. For example, one end of the charging connector 4 is located on the outer wall of the housing 1, and the other end is located inside the housing 1 and electrically connected to the electrical component 3. It is understood that the charging connector 4 is used to electrically connect to the charger 18 and to connect or disconnect the charger 18 from the charging / discharging circuit 20.

[0063] At least a portion of the discharge connector 5 is located on the outer wall of the housing 1. The discharge connector 5 is electrically connected to the electrical component 3. For example, one end of the discharge connector 5 is located on the outer wall of the housing 1, and the other end is located inside the housing 1 and electrically connected to the electrical component 3. It is understood that the discharge connector 5 is used to electrically connect to the load and to connect or disconnect the load from the charge / discharge circuit 20.

[0064] In this embodiment, the power supply control device can be moved from the traditional top cover position to the side wall of the battery pack housing, avoiding stacking on the top cover, thereby reducing the space occupied by the battery pack in the thickness direction. This allows the use of the side space of the housing instead of the height space, which is more suitable for the layout requirements of vehicles that are sensitive to thickness.

[0065] In addition, by covering the electrical components 3 with the outer casing 1, the electrical components 3 are prevented from being directly exposed to the external environment, thus improving the protection of the electrical components 3. Furthermore, in case of a fault, the outer casing 1 can be directly removed without removing the entire battery pack top cover, reducing the difficulty of repair and maintenance.

[0066] By placing the charging connector 4 and the discharging connector 5 on the outer wall of the housing 1 and exposing them directly to the outside, they can be connected to the corresponding equipment (charger 18 or load) on the vehicle without complicated internal searching or passing through other parts, which can significantly improve the convenience of connection.

[0067] The electrical component 3 is arranged on the mounting base 2, which serves as an intermediate carrier. This allows external impacts (such as bumps and collisions) to be evenly distributed to the housing 1, rather than directly affecting the electrical component 3, thus extending the component's lifespan. Furthermore, during assembly, the electrical component 3 can be pre-assembled and tested (e.g., for circuit continuity) on the mounting base 2 before being fully installed into the housing 1, simplifying the production line process.

[0068] In some embodiments provided by this utility model, the power supply control device further includes a flexible circuit board 6 and a battery management module 7.

[0069] The flexible circuit board 6 is disposed at one end of the electrical component 3 and is electrically connected to the electrical component 3. For example, the flexible circuit board 6 has corresponding docking ports at positions opposite to the electrical component 3.

[0070] The battery management module 7 is located on the side of the flexible circuit board 6 away from the electrical component 3 and is electrically connected to the flexible circuit board 6.

[0071] In this embodiment, the flexible circuit board 6 is disposed between the battery management module 7 and the electrical component 3 and connects the two. It can serve as a bridge between the high-voltage and low-voltage systems. At the same time, the flexible circuit board 6 can replace the bulky wiring harness and better adapt to the vibration environment.

[0072] The battery management module 7 is fixed to the back of the flexible circuit board 6. It can directly read the status signals (such as temperature and voltage) of the electrical components 3 to achieve real-time monitoring and control the on / off state of the electrical components 3.

[0073] In some embodiments provided by this utility model, electrical components 3, flexible circuit boards 6 and battery management modules 7 are arranged sequentially along the direction from the opening 101 to the inside of the outer casing 1.

[0074] In this embodiment, the electrical components 3, the flexible circuit board 6, and the battery management module 7 are arranged in sequence along the opening 101, which can make full use of the depth space of the outer shell 1, avoid the increase in volume caused by lateral expansion (i.e., the thickness direction of the battery pack), and maintain the flatness of the battery pack sidewalls.

[0075] In addition, the electrical component 3 can be directly connected to the battery in the battery pack through the opening 101, which shortens the connection distance between the electrical component 3 and the battery in the battery pack, eliminating the need for complex wiring layout and excessively long connection harnesses, thus shortening the connection path.

[0076] In some embodiments provided by this utility model, there are multiple electrical components 3, including a fuse 305, and a first mounting port 102 is provided at the position opposite to the fuse 305 on the housing 1.

[0077] Accordingly, the power supply control device also includes a first cover plate 8 connected to the housing 1, the first cover plate 8 being used to open and close the first mounting port 102.

[0078] In this embodiment, a first mounting port 102 is provided and equipped with a first cover plate 8. Without disassembling the entire power supply control device or opening other parts of the outer casing 1, the fuse 305 can be operated directly through the first mounting port 102, such as for inspection or replacement. This greatly improves the convenience and efficiency of maintenance and reduces maintenance time and cost.

[0079] In addition, the first cover plate 8 can enclose the fuse 305 inside the housing 1 when it is working normally, preventing personnel from accidentally coming into contact with the fuse 305 and avoiding safety accidents such as electric shock. At the same time, the cover plate also plays a certain protective role, preventing dust, moisture and other substances from entering and affecting the performance and life of the fuse 305, ensuring that the fuse 305 works in a safe and stable environment.

[0080] Optionally, the orientation of the first mounting port 102 is opposite to that of the opening 101, or in other words, the first mounting port 102 and the opening 101 are respectively disposed on opposite side walls of the housing 1.

[0081] In this embodiment, opening 101 is used to connect electrical component 3 to the battery in the battery pack, which involves a lot of wiring connections and related operations. By placing the first mounting port 102 on the opposite side, the installation and maintenance area of ​​fuse 305 is relatively separated from the electrical connection area at opening 101, which can avoid interference with the wiring connections at opening 101 when operating fuse 305.

[0082] Optionally, the first cover plate 8 can be detachably connected to the outer casing 1 by threaded fasteners, or the first cover plate 8 can be rotatably or slidably connected to the outer casing 1, thereby opening and closing the first mounting port 102 by rotation or sliding.

[0083] In some embodiments provided by this utility model, the outer shell 1 is provided with a second mounting port 103. The second mounting port 103 and the charging connector 4 are disposed on two opposite side walls of the outer shell 1, and the second mounting port 103 and the charging connector 4 are disposed opposite to each other. Specifically, in the extending direction of the charging connector 4, the second mounting port 103 and the charging connector 4 are opposite to each other.

[0084] Accordingly, the power supply control device also includes a second cover plate 9 connected to the housing 1, the second cover plate 9 being used to open and close the second mounting port 103.

[0085] In this embodiment, the second mounting port 103 facilitates the arrangement and connection of internal wiring, making it easier for the wiring introduced from the charging connector 4 to connect to the corresponding electrical components 3, thereby reducing the difficulty of wiring connection.

[0086] Furthermore, the second mounting port 103 provides a dedicated access point for the maintenance of the charging connector 4. During installation or maintenance, personnel can directly access the charging connector 4 through the second mounting port 103 without disassembling the entire housing 1 or performing other complex operations, thus reducing the difficulty of installation and maintenance and saving time and labor costs.

[0087] Furthermore, the second cover 9 can be closed when the second mounting port 103 is not in use, preventing foreign objects from entering the housing 1 and avoiding safety accidents such as short circuits caused by foreign objects contacting the internal circuitry. At the same time, it also provides a certain degree of dust and moisture protection, protecting the performance and lifespan of the internal electrical components 3 and ensuring that the power supply control device operates in a safe environment.

[0088] Optionally, the orientation of the second mounting opening 103 intersects the orientation of the opening 101; for example, the orientation of the second mounting opening 103 is perpendicular to the orientation of the opening 101. In other words, the second mounting opening 103 is disposed on a side wall of the housing 1 surrounding the edge of the opening 101. This arrangement makes full use of the space around the opening 101 of the housing 1 and avoids increasing the size of the housing 1 in the orientation direction of the opening 101.

[0089] Furthermore, with the battery pack installed in the vehicle, the charging connector 4 is positioned downwards.

[0090] In this embodiment, the downward orientation allows gravity to prevent dust and debris from easily entering the charging connector 4. At the same time, in humid environments or when the vehicle is washed, water can flow down naturally, preventing water accumulation at the charging connector 4. This reduces problems such as short circuits and corrosion caused by foreign objects or water accumulation, thereby improving the reliability and service life of the connector.

[0091] Furthermore, the downward-facing charging connector 4 facilitates the layout and installation of the internal wiring of the battery pack. For example, the wiring can naturally extend along the bottom or side of the battery pack to the charging connector 4, making the wiring neater and simpler, reducing bends and intersections, and making it easier for installers to operate.

[0092] Optionally, the second cover plate 9 can be detachably connected to the outer casing 1 by threaded fasteners, or the second cover plate 9 can be rotatably or slidably connected to the outer casing 1, thereby opening and closing the second mounting port 103 by rotation or sliding.

[0093] In some embodiments provided by this utility model, the outer shell 1 is provided with a third mounting port 104. The third mounting port 104 and the discharge connector 5 are disposed on two opposite side walls of the outer shell 1, and the third mounting port 104 and the discharge connector 5 are disposed opposite to each other. Specifically, along the extension direction of the discharge connector 5, the third mounting port 104 and the discharge connector 5 are disposed opposite to each other.

[0094] Accordingly, the power supply control device also includes a third cover plate 10 connected to the housing 1, the third cover plate 10 being used to open and close the third mounting port 104.

[0095] In this embodiment, the third mounting port 104 facilitates the arrangement and connection of internal wiring, enabling the wiring introduced from the discharge connector 5 to be more conveniently connected to the corresponding electrical components 3, thereby reducing the operational difficulty of wiring connection.

[0096] Furthermore, the third mounting port 104 provides a dedicated access point for the maintenance of the discharge connector 5. During installation or maintenance, personnel can directly access the discharge connector 5 through the third mounting port 104 without disassembling the entire housing 1 or performing other complex operations, thus reducing the difficulty of installation and maintenance and saving time and labor costs.

[0097] Furthermore, the third cover 10 can be closed when the third mounting port 104 is not in use, preventing foreign objects from entering the housing 1 and avoiding safety accidents such as short circuits caused by foreign objects contacting the internal circuitry. At the same time, it also provides a certain degree of dust and moisture protection, protecting the performance and lifespan of the internal electrical components 3 and ensuring that the power supply control device operates in a safe environment.

[0098] Optionally, the orientation of the third mounting opening 104 intersects the orientation of the opening 101; for example, the orientation of the third mounting opening 104 is perpendicular to the orientation of the opening 101. In other words, the third mounting opening 104 is disposed on a side wall of the housing 1 surrounding the edge of the opening 101. This arrangement makes full use of the space around the opening 101 of the housing 1 and avoids increasing the size of the housing 1 in the orientation direction of the opening 101.

[0099] Furthermore, with the battery pack installed in the vehicle, the discharge connector 5 is positioned downwards.

[0100] In this embodiment, the downward orientation allows gravity to prevent dust and debris from easily entering the discharge connector 5. At the same time, in humid environments or when the vehicle is washed, water can flow down naturally, preventing water accumulation at the discharge connector 5. This reduces problems such as short circuits and corrosion caused by foreign objects or water accumulation, thereby improving the reliability and service life of the connector.

[0101] Furthermore, the downward-facing discharge connector 5 facilitates the layout and installation of the internal wiring of the battery pack. For example, the wiring can naturally extend along the bottom or side of the battery pack to the discharge connector 5, making the wiring neater and simpler, reducing bends and intersections, and making it easier for installers to operate.

[0102] Optionally, the third cover plate 10 can be detachably connected to the housing 1 by threaded fasteners, or the third cover plate 10 can be rotatably or slidably connected to the housing 1, thereby opening and closing the third mounting port 104 by rotation or sliding.

[0103] Optionally, the charging connector 4 and the discharging connector 5 are both located on the same side wall of the housing 1. Concentrating the charging and discharging lines on the same side wall facilitates the planning and layout of the lines, reduces line crossings and lengths, lowers line resistance, improves circuit efficiency, and also facilitates the fixing and protection of the lines.

[0104] For maintenance personnel, two joints on the same side wall facilitate simultaneous inspection, repair, and replacement operations, eliminating the need to work in multiple locations, thus improving maintenance efficiency and reducing maintenance costs.

[0105] In some embodiments provided by this utility model, a first recess 105 is provided on the outer wall of the outer shell 1, and the charging connector 4 is disposed in the first recess 105, and the charging connector 4 does not protrude from the first recess 105.

[0106] In this embodiment, the charging connector 4 is disposed within the first recess 105 without increasing the overall size of the housing 1 in that direction. For example, even if the charging connector 4 extends along the thickness direction of the battery pack, it will not increase the size of the power supply control device in the thickness direction of the battery pack.

[0107] In addition, the recess provides a protective space for the charging connector 4. For example, when the battery pack is in a vehicle or during transportation or use, when an external object comes into contact with the battery pack casing 1, the outer wall of the casing 1 is the first point of contact. However, since the charging connector 4 is located in the recess, it is protected by the surrounding walls and is less likely to collide directly with external objects.

[0108] In some embodiments provided by this utility model, a second recess 106 is provided on the outer wall of the outer shell 1, the discharge connector 5 is disposed in the second recess 106, and the discharge connector 5 does not protrude from the second recess 106.

[0109] In this embodiment, the discharge connector 5 is disposed within the second recess 106 without increasing the overall size of the housing 1 in that direction. For example, even if the discharge connector 5 extends along the thickness direction of the battery pack, it will not increase the size of the power supply control device in the thickness direction of the battery pack.

[0110] In addition, the recess provides a protective space for the discharge connector 5. For example, when the battery pack is in a carrier or during transportation or use, when an external object comes into contact with the battery pack casing 1, the outer wall of the casing 1 is the first point of contact. However, since the discharge connector 5 is located in the recess, it is protected by the surrounding walls and is less likely to collide directly with external objects.

[0111] refer to Figure 2 As shown, in some embodiments provided by this utility model, the outer shell 1 is configured as a strip structure extending along the first direction X, with the opening 101 facing the second direction Y, the second direction Y intersecting with the first direction X, and the charging connector 4 and the discharging connector 5 respectively disposed at both ends of the outer shell 1 along the first direction X.

[0112] Optionally, the first direction X is the transverse direction of the vehicle, and the second direction Y is the longitudinal direction of the vehicle. Of course, in other cases, the first direction X can also be the longitudinal direction of the vehicle, and the second direction Y is the transverse direction of the vehicle.

[0113] In this embodiment, the charging connector 4 and the discharging connector 5 are arranged at both ends, which helps to separate the circuits with different functions, reduce electromagnetic interference between the circuits, thereby helping to improve the stability and reliability of the battery pack electrical system and reduce the risk of failure caused by circuit interference.

[0114] In addition, placing the charging connector 4 and the discharging connector 5 at opposite ends can prevent heat from concentrating in one place, reduce the impact of high temperature on other components, and improve the safety and stability of the entire battery pack.

[0115] In some embodiments provided by this utility model, the electrical component 3 is arranged opposite to the opening 101, and the power supply control device also includes a conductive component 11 and a cold plate 12.

[0116] The conductive element 11 is located on the side of the electrical component 3 closest to the opening 101, or in other words, on the side of the electrical component 3 furthest from the flexible circuit board 6. The conductive element 11 is electrically connected to the electrical component 3 and is used to connect the electrical component 3 to the charging / discharging circuit 20. The conductive element 11 can be a metal busbar, including but not limited to copper busbars. Optionally, the conductive element 11 and the mounting base 2 are integrally injection molded, for example, through insert injection molding.

[0117] The cold plate 12 is disposed on the side of the conductive element 11 near the opening 101 and is used to cool the conductive element 11, that is, the cold plate 12 is disposed on the side of the conductive element 11 away from the electrical component 3. Optionally, the cold plate 12 includes, but is not limited to, a liquid cooling plate.

[0118] In this embodiment, since the cold plate 12 is located near the opening 101, its pipes can directly enter the battery pack housing from the opening 101, reducing the pipe path length and layout difficulty. Furthermore, the cold plate 12 can share the coolant circulation system with the cooling plate in the battery pack, thus eliminating the need to design a separate coolant circulation system for the cold plate 12, reducing the number and complexity of the cooling system components.

[0119] Furthermore, the cold plate 12 is located on the side of the conductive component 11 away from the electrical component 3, so the pipes of the cold plate 12 can directly pass through the opening 101 into the battery pack housing without interfering with the conductive component 11 or the electrical component 3.

[0120] Optionally, the cold plate 12 can be fixed to the mounting base 2 by threaded fasteners, so that the cold plate 12, electrical components 3, battery management system and flexible circuit board 6 can be integrated with the mounting base 2, thereby allowing pre-assembly, installation and disassembly of the mounting base 2 as a unit, thus reducing the difficulty of assembly and debugging and disassembly.

[0121] In some embodiments provided by this utility model, the connecting part includes a connecting flange 107, which is disposed around the edge of the opening 101 and is used to connect to the battery pack housing. For example, the connecting flange 107 can be screwed, glued, or welded to the battery pack housing.

[0122] In this embodiment, by providing the connecting flange 107, the connection area between the outer shell 1 and the housing can be increased, thereby improving the connection strength and stability between the outer shell 1 and the housing. Furthermore, a sealing element, such as a gasket or sealant, can be provided between the connecting flange 107 and the side wall of the housing.

[0123] refer to Figure 2 As shown, in some embodiments of this utility model, the connecting part includes a mounting groove 108, which is provided on the side wall of the outer casing 1 circumferentially to the opening 101. A through mounting hole 109 is provided on the inner wall of the mounting groove 108 near the opening 101, and the mounting hole 109 is used to connect with the battery pack housing. For example, the mounting hole 109 is used for a threaded connector to pass through, and the threaded connector passes through the mounting hole 109 and is threadedly connected to the housing.

[0124] In this embodiment, the mounting groove 108 is provided on the side wall of the housing 1 located around the opening 101. This can make full use of the space inside the housing 1 and avoid setting up a special mounting structure in other positions of the housing 1, thereby not increasing the external size of the housing 1.

[0125] refer to Figure 10 As shown, in some embodiments provided by this utility model, the mounting base 2 has a plurality of mounting positions 201, including a first mounting position 2011, a second mounting position 2012 and a third mounting position 2013.

[0126] The first mounting position 2011 is equipped with electrical component 3, the second mounting position 2012 can be selectively equipped with step-up switch assembly 13 or left empty, and the third mounting position 2013 can be selectively equipped with step-down switch assembly 14 or left empty.

[0127] Electrical component 3, boost switch assembly 13, and buck switch assembly 14 can all be connected to the charging / discharging circuit 20 via corresponding conductive elements 11. It is understood that each mounting position 201 is pre-installed with a corresponding conductive element 11. After arranging electrical component 3, boost switch assembly 13, or buck switch assembly 14 in the corresponding mounting position 201, connecting them to the corresponding conductive element allows them to be connected to the charging / discharging circuit 20.

[0128] The boost switch assembly 13 can connect or disconnect the windings of the motor assembly from the charging and discharging circuit 20. Specifically, the boost switch assembly 13 can connect the motor assembly to the charging and discharging circuit 20 and make the motor assembly boost the voltage during the charging process or depress the voltage during the discharging process.

[0129] The step-down switch assembly 14 can connect or disconnect the windings of the motor assembly from the charging and discharging circuit 20. Specifically, the step-down switch assembly 14 can connect the motor assembly to the charging and discharging circuit 20 and make the motor assembly step down the voltage during the charging process or step up the voltage during the discharging process.

[0130] In this embodiment, the mounting base 2 is provided with standardized mounting positions 201, including a first mounting position 2011, a second mounting position 2012 and a third mounting position 2013. By selectively assembling the boost switch assembly 13 and the buck switch assembly 14 or leaving them empty, it can flexibly adapt to the needs of different voltage platforms.

[0131] For example, installing the boost switch assembly 13 can match the high-voltage requirements of the platform, so that the power supply control device can be adapted to the high-voltage platform. Installing the buck switch assembly 14 can match the low-voltage requirements of the platform, so that the power supply control device can be adapted to the low-voltage platform. Similarly, leaving the second mounting position 2012 and the third mounting position 2013 empty can also make the power supply control device adaptable to the low-voltage platform.

[0132] In addition, by arranging the boost switch assembly 13 and the buck switch assembly 14 in the second mounting position 2012 and the third mounting position 2013 respectively, the high voltage or low voltage requirements of the platform can be matched so that the power supply control device can be adapted to the medium voltage platform.

[0133] By reusing the motor assembly (boost / buck mode switching), the circuit voltage can be adjusted during charging or discharging, reducing the need for additional voltage conversion devices and lowering hardware complexity.

[0134] In summary, this embodiment achieves platform universality for the power supply control device through the design of "standardized mounting base + optional functional modules", solves the problem of multi-voltage platform adaptation, and combines economy, flexibility and scalability.

[0135] refer to Figure 14 As shown, in some embodiments provided by this utility model, there are multiple electrical components, including a fast charging positive relay 301, a main positive relay 302, a main negative relay 303, and a fast charging negative relay 304.

[0136] The fast-charging positive relay 301 is used to connect the positive terminals of both the charger 18 and the power battery 15. That is, the two connection terminals 3011 of the fast-charging positive relay 301 are respectively connected to the positive terminals of the charger 18 and the power battery 15.

[0137] One end of the main positive relay 302 is connected to one end of the fast charging positive relay 301 connected to the power battery 15, and the other end is used to connect to the load. That is, one connection terminal 3011 of the main positive relay 302 is connected to the connection terminal 3011 of the fast charging positive relay 301 connected to the power battery 15, and the other connection terminal 3011 of the main positive relay 302 is connected to the load.

[0138] Optionally, the load includes a motor assembly, which includes a motor 16 and an inverter 17 connected in series with the motor 16. The inverter 17 can convert the DC power from the power battery 15 into AC power and transmit it to the motor 16. The main positive relay 302 is connected to the positive terminal of the inverter 17.

[0139] The main negative relay 303 is used to connect the negative terminal of the power battery 15 to the load. That is, one connection terminal 3011 of the main negative relay 303 is connected to the negative terminal of the power battery 15, and the other connection terminal 3011 is connected to the load, that is, to the negative terminal of the inverter 17.

[0140] One end of the fast-charging negative relay 304 is connected to one end of the main negative relay 303 connected to the load, and the other end is used to connect to the negative terminal of the charger 18. That is, one connection terminal 3011 of the fast-charging negative relay 304 is connected to the connection terminal 3011 of the main negative relay 303 connected to the load, and the other connection terminal 3011 of the fast-charging negative relay 304 is used to connect to the negative terminal of the charger 18.

[0141] In this embodiment, during charging, the fast charging positive relay 301, fast charging negative relay 304 and main negative relay 303 are closed; during driving, the main positive relay 302 and main negative relay 303 are closed.

[0142] Among them, the main negative relay 303 serves both the drive and charging circuits. The fast charging negative relay 304 extends the path during charging, which can reduce the number of redundant relays.

[0143] It is understood that, in this embodiment, relays that are connected can be connected to each other via conductive element 11.

[0144] refer to Figure 14 As shown, in some embodiments provided by this utility model, the boost switch assembly 13 includes a boost relay 1301. One end of the boost relay 1301 is used to connect to the positive terminal of the charger 18, and the other end is used to connect to the winding of the motor assembly.

[0145] Specifically, one connection terminal 3011 of the boost relay 1301 is used to connect to the positive terminal of the charger 18. For example, this connection terminal 3011 can be connected to the connection terminal 3011 of the fast charging positive relay 1301 connected to the charger 18. The other connection terminal 3011 of the boost relay 1301 is used to connect to the three-phase windings of the motor assembly. For example, this connection terminal 3011 can be connected to the three-phase center point, the three-phase busbar, or any point of the three-phase windings.

[0146] In this embodiment, the motor assembly can be used to boost the voltage during charging. Specifically, the boost relay 1301, main positive relay 302, main negative relay 303, and fast-charging negative relay 304 are closed. The positive current passes through the boost relay 1301, the windings of the motor 16, the inverter 17, and the main positive relay 302 to enter the power battery 15, while the negative current passes through the power battery 15, the main negative relay 303, and the fast-charging negative relay 304 to enter the charger 18.

[0147] Furthermore, during the discharge process, the motor assembly can be used to reduce the voltage. Specifically, this involves closing the boost relay 1301, the main positive relay 302, the main negative relay 303, and the fast-charging negative relay 304. The relays operate in the same state as during the charging process, and the direction of current flow can be analyzed similarly.

[0148] This setup allows for voltage conversion using the motor assembly, reducing cost and weight, and the same relay topology supports various operating conditions such as boost charging, buck power supply, and normal drive.

[0149] refer to Figure 14 As shown, in some embodiments provided by this utility model, the step-down switch assembly 14 includes a step-down relay 1401, one end of which is used to connect to the winding of the motor assembly, and the other end is used to connect to the negative terminal of the power battery 15.

[0150] Specifically, one connection terminal 3011 of the step-down relay 1401 is used to connect to the negative terminal of the power battery 15. For example, this connection terminal 3011 can be connected to the connection terminal 3011 of the main negative relay 303 connected to the power battery 15. The other connection terminal 3011 of the step-down relay 1401 is used to connect to the three-phase windings of the motor assembly. For example, this connection terminal 3011 can be connected to the three-phase center point, the three-phase busbar, or any point of the three-phase windings.

[0151] Specifically, the step-down relay 1401 is connected to the motor assembly's connection terminal 3011, and the step-up relay 1301 is connected to the motor assembly's connection terminal 3011.

[0152] In this embodiment, the motor assembly can be used to step down the voltage during charging. Specifically, the fast-charging positive relay 301, fast-charging negative relay 304, and step-down relay 1401 are closed, while the main positive relay 302 and main negative relay 303 are opened. The positive current enters the power battery 15 through the positive terminal of the charger 18 and the fast-charging positive relay 301, while the negative current enters the charger 18 through the negative terminal of the power battery 15, the step-down relay 1401, the windings of the motor 16, the inverter 17, and the fast-charging negative relay 304.

[0153] During the discharge process, the motor assembly can be used to boost the voltage. Specifically, the fast charging positive relay 301, fast charging negative relay 304 and buck relay 1401 are closed, and the main positive relay 302 and main negative relay 303 are disconnected.

[0154] This setup allows for voltage conversion using the motor assembly, reducing cost and weight, and the same relay topology supports various operating conditions such as buck charging, boost power supply, and normal drive.

[0155] refer to Figure 14 As shown, in some embodiments provided by this utility model, the boost switch assembly 13 further includes a first capacitor 1302 and a capacitor switch relay 1303.

[0156] The first capacitor 1302 and the capacitor switch relay 1303 are connected in series between one end of the boost relay 1301 that connects the charger 18 and the negative terminal of the power battery 15.

[0157] For example, one connection terminal 3011 of the capacitor switch relay 1303 is connected to the connection terminal 3011 of the main negative relay 303 connected to the power battery 15, and the other connection terminal 3011 of the capacitor switch relay 1303 is connected to the connection terminal 3011 of the first capacitor 1302. The other connection terminal 3011 of the first capacitor 1302 is connected to the connection terminal 3011 of the fast charging relay connected to the charger 18. Of course, the positions of the capacitor switch relay 1303 and the first capacitor 1302 can be interchanged.

[0158] In this embodiment, before performing boost charging using the motor assembly, the capacitor switch relay 1303 can be closed, and the first capacitor 1302 can be charged through the power battery 15 before boost charging. This configuration allows the first capacitor 1302 to suppress instantaneous voltage surges during charger 18 startup, protecting power devices such as relay contacts, the power battery 15, and the inverter 17.

[0159] refer to Figure 14As shown, optionally, the multiple electrical components 3 also include a pre-charge module 306. The pre-charge module 306 is connected in parallel with the main positive relay 302. Before closing the fast charging relay to charge the power battery 15, the pre-charge module 306 can be opened first to charge the corresponding capacitor, and then the fast charging positive relay 301 can be opened to charge, so as to avoid the instantaneous voltage surge when the charger 18 starts from impacting the relay contacts or the power battery 15.

[0160] For example, the precharge module 306 includes a resistor and a precharge relay 3061 connected in series.

[0161] In some embodiments provided by this utility model, multiple electrical components 3 also include a fuse 305. The fast-charging positive relay 301 and the main positive relay 302 are both connected to the power battery 15 through the fuse 305. When an abnormal situation occurs during charging and discharging that causes excessive current, such as a short circuit in the electrical component 3 or a circuit fault, the fuse 305 will melt due to overheating, quickly disconnecting the circuit connection of the power battery 15 and preventing excessive current from damaging the power battery 15 and other related electrical equipment.

[0162] refer to Figure 12 and Figure 13 As shown, in some embodiments provided by this utility model, the fast charging positive relay 301 has a connection terminal 3011, a sampling terminal 3012, and a control terminal 3013. For example, the connection terminal 3011 is disposed at one end of the fast charging positive relay 301, and the sampling terminal 3012 and the control terminal 3013 are disposed at the other end of the fast charging positive relay 301.

[0163] There are two connecting terminals 3011, which are connected to the moving contact and the stationary contact respectively. The connecting terminals 3011 are used to connect different conductive parts 11.

[0164] Sampling terminal 3012 is electrically connected to the moving or stationary contact, and control terminal 3013 is electrically connected to the electromagnetic component. Both sampling terminal 3012 and control terminal 3013 are used to connect to the flexible circuit board 6 so that the flexible circuit board 6 can collect the voltage signal of the fast charging positive relay 301 or transmit control signals to the fast charging positive relay 301.

[0165] It is understood that the electrical component 3 or relay involved in this application can adopt the same structure as the fast charging positive relay 301.

[0166] Optionally, refer to Figure 13As shown, the connection terminal 3011 includes a first shaft segment and a second shaft segment. One end of the first shaft segment is located inside the fast-charging positive relay 301, and the other end protrudes from the end face of the fast-charging positive relay 301. The second shaft segment is connected to the end of the first shaft segment that protrudes from the end face of the fast-charging positive relay 301. The cross-sectional area of ​​the first shaft segment is larger than the cross-sectional area of ​​the second shaft segment.

[0167] Correspondingly, the conductive component 11 is provided with a connecting hole 1101 for the second shaft segment to be inserted. The conductive component 11 abuts against the end face of the first shaft segment, and the second shaft segment is welded to the wall of the connecting hole 1101.

[0168] In this embodiment, along the axial direction of the connecting terminal 3011, the first shaft segment can block the gap between the second shaft segment and the connecting hole 1101, which can prevent the welding heat from penetrating and affecting the housing 1 of the fast charging relay.

[0169] In some embodiments of this utility model, the mounting base 2 is provided with a plurality of receiving chambers 202, and adjacent receiving chambers 202 are separated by partitions. Each mounting position 201 includes a corresponding receiving chamber 202; for example, the mounting position 201 may include one or more receiving chambers 202.

[0170] In this embodiment, the housing 202 provides a clear installation location for the components, making it convenient for workers or robots to install and position the components, thus improving installation efficiency.

[0171] Optionally, the receiving chamber 202 is provided with an opening 101 through which the electrical component 3, the boost switch assembly 13, or the buck switch assembly 14 can pass, so as to facilitate the installation and removal of the electrical component 3, the boost switch assembly 13, or the buck switch assembly 14.

[0172] Furthermore, the conductive element 11 is disposed at the end of the receiving chamber 202 away from the opening 101, that is, the opening 101 and the conductive element 11 are respectively disposed at both ends of the receiving chamber 202. The end face of one end of the conductive element 11 faces the receiving chamber 202 and is used to connect with a corresponding component inside the receiving chamber 202, and the end face of the other end of the conductive element 11 is exposed on the surface of the mounting base 2 and is used to fit against the cold plate 12.

[0173] In this embodiment, the conductive component 11 is placed at the end of the receiving chamber 202 away from the opening 101. This does not affect the installation and removal of the component through the opening 101, and makes full use of the space of the receiving chamber 202. This makes the connection layout of the conductive component 11 with the component and the cold plate 12 more reasonable and compact, effectively saving installation space and facilitating the miniaturization design of the entire device.

[0174] Furthermore, one end of the conductive component 11 faces into the housing 202 and connects to the corresponding component, ensuring a good electrical connection, reducing contact resistance, and lowering the risk of overheating and failure due to poor contact. Simultaneously, its other end is attached to the cold plate 12, ensuring stable heat dissipation, thereby ensuring reliable operation of the entire system in terms of both electrical and heat dissipation performance.

[0175] Optionally, the flexible circuit board 6 is also configured to be selectively electrically connected to the boost switch assembly 13 and / or the buck switch assembly 14. For example, the flexible circuit board 6 has corresponding docking ports at positions opposite to the electrical component 3, the boost switch assembly 13, and the buck switch assembly 14.

[0176] Further, refer to Figure 9 As shown, a clearance hole 601 is provided on the flexible circuit board 6 at a position opposite to the electrical component 3, the boost switch assembly 13 or the buck switch assembly 14. For example, the clearance hole 601 is arranged opposite to the terminal of the electrical component 3, the boost switch assembly 13 or the buck switch assembly 14, where the terminal is the control terminal 3013 or the sampling terminal 3012.

[0177] This configuration, with the clearance hole 601 positioned opposite the terminal, allows the terminal to pass through, facilitating alignment and positioning of the terminal with the corresponding port on the flexible circuit board 6. This ensures accurate soldering of the metal sheet 19 to the terminals and the port of the flexible circuit board 6 during welding, improving welding accuracy and reliability, reducing welding defects such as incomplete soldering and missed soldering, and guaranteeing the stability of the electrical connection.

[0178] Optionally, refer to Figure 8 As shown, the battery management module 7 includes a sub-circuit board 701 and a flexible connector 702. The number of sub-circuit boards 701 is at least two, and the flexible connector 702 is electrically connected between the two sub-circuit boards 701.

[0179] With this arrangement, multiple sub-circuit boards 701 are distributed in a dispersed manner. Compared to a single large-size circuit board, each sub-circuit board 701 is smaller in size. When subjected to external impact or stress caused by factors such as thermal expansion and contraction, the stress borne by each individual sub-circuit board 701 is relatively small due to its small area, making it less prone to cracking.

[0180] Moreover, the flexible connector 702 can buffer and disperse stress to a certain extent. When the sub-circuit board 701 undergoes slight displacement or deformation due to various factors, the flexible connector 702 can adapt through its own deformation, reducing mutual pulling and stress concentration between the sub-circuit boards 701, thereby reducing the risk of breakage.

[0181] Furthermore, at least two sub-circuit boards 701 can be arranged in the same plane, parallel, or at an angle.

[0182] This utility model also provides a battery pack in this embodiment.

[0183] Specifically, the battery pack includes the power supply control device described above.

[0184] The battery pack includes a power supply control device, and therefore also includes all the advantages of the power supply control device mentioned above, so it will not be elaborated further.

[0185] This utility model also provides a vehicle in its embodiments.

[0186] Specifically, the vehicle includes a power supply control device as described above or a battery pack as described above.

[0187] The vehicle includes a power supply control device, and therefore also includes all the advantages of the power supply control device mentioned above, so it will not be elaborated further.

[0188] In addition, vehicles include, but are not limited to, vehicles, aircraft, and boats.

[0189] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
