[0027] The features and exemplary embodiments of various aspects of the utility model will be described in detail below. In the detailed description below, many specific details are proposed in order to provide a comprehensive understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without the need for some of these specific details. The following description of the embodiment is only to provide a better understanding of the utility model by illustrating an example of the utility model. In the drawings and the following description, at least part of the known structures and technologies are not shown in order to avoid unnecessary ambiguity to the utility model; and, for clarity, the size of some structures may be exaggerated. In addition, the features, structures or characteristics described below may be combined in one or more embodiments in any suitable manner.

[0028] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of the battery energy distribution device and battery of the utility model. In the description of the utility model, it should also be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to the specific circumstances.

[0029] In order to better understand the present invention, Figures 1 to 6 The battery energy distribution device and the battery in the embodiment of the utility model are described in detail.

[0030] See also Figures 1 to 4 The embodiment of the utility model proposes a battery energy distribution device 100, including a carrier 10, a relay 20 and a power connection circuit 30, wherein the relay 20 is arranged on the carrier 10; the power connection circuit 30 is arranged on the carrier 10, and the power connection circuit 30 has an external terminal 31 and an internal terminal 32 arranged opposite to each other, the internal terminal 32 is connected to the relay 20, and the power connection circuit 30 is connected to the battery cell through the external terminal 31; wherein a docking port 40 is arranged on the relay 20, and the docking port 40 is located at an end of the relay 20 away from the carrier 10, and the relay 20 is connected to the electrical device through the docking port 40.

[0031] The battery energy distribution device 100 provided in the utility model is a BDU controller in a battery pack. The battery energy distribution device 100 is an important component in the high-voltage circuit of an electric vehicle, which controls the power-on and power-off processes, pre-charging process, and charging process of the electrical circuit.

[0032] As for the internal structure of the battery energy distribution device 100 , there is a carrier 10 . Optionally, the carrier 10 may be a plate-like structure, and its main function is to carry various electrical components. Each electrical component can be directly set on the carrier 10 .

[0033] The relay 20 determines the on and off of the power connection circuit 30. Optionally, the relay 20 has multiple forms and needs to be set at multiple locations of the power connection circuit 30. For example, relays 20 need to be set respectively on the lines connecting the positive and negative poles of the battery cell, and relays 20 need to be set on the charging supply circuit and loop. Therefore, the utility model does not specifically limit the form and setting position of the relay 20, and multiple relays 20 can be applied to the setting position of the docking port 40 in the utility model.

[0034] Optionally, the power connection line 30 can be a high-voltage copper busbar, which has a relative external terminal 31 and an internal terminal 32. Since there are multiple power connection lines 30, there are multiple external terminals 31 at different positions, and the internal terminals 32 are all connected to their respective relays 20.

[0035] The battery energy distribution device 100 can be connected to an external battery cell through the external terminal 31, and the current enters the relay 20 through the conduction of the power connection line 30. The relay 20 has the function of an on-off switch. The relay 20 is further connected to an external electrical device through the docking port 40 on the top. Optionally, the electrical device can be a car power connection component, so that the battery cell can supply power to the car. Of course, the battery cell can also be charged by an external power source.

[0036] In the present embodiment, the docking port 40 for external connection is arranged at the end of the relay 20 away from the carrier 10, that is, on the top surface of the battery energy distribution device 100. When the staff needs to connect an external electrical device, they directly plug the line into the top surface of the battery energy distribution device 100, avoiding the problem of inconvenience in plugging caused by the small space around the battery energy distribution device 100. The docking port 40 on the top surface greatly improves the convenience of plugging and unplugging operations.

[0037] Optionally, the docking port 40 may be a square port, which can also appropriately increase the plug-in area and facilitate plug-in and pull-out operations. The present invention does not impose any special restrictions on the shape and size of the docking port 40 .

[0038] The embodiment of the utility model provides a battery energy distribution device 100, by arranging the relay 20 on the carrier 10 and arranging the docking port 40 at the end of the relay 20 away from the carrier 10, the docking port 40 is used to form an electrical connection with an external electrical device, so that the docking port 40 is arranged on the top surface of the relay 20, and the staff can perform top plug-in on the relay 20, avoiding the side plug-in of the relay 20 in the prior art, and preventing the problem of inconvenience in plugging due to space limitations in the battery pack, so that there is a larger operating space during the plug-in process of the relay 20, which improves the operating convenience of the staff, makes it easy to complete the connection operation of the relay 20, is not affected by the space around the battery energy distribution device 100, and has better connection performance.

[0039] As an alternative embodiment, see Figure 3 and Figure 4 The battery energy distribution device 100 includes a support plate 50, which is arranged on the carrier 10 and intersects with the plane where the carrier 10 is located, and the relay 20 is connected to the support plate 50 through its side wall.

[0040] Considering that after the docking port 40 on the relay 20 is set toward the top surface, the stability of the relay 20 needs to be ensured during the operation of the overall equipment, in this embodiment, a support plate 50 is set on the carrier 10, and the relay 20 is connected to the support plate 50, so that the relay 20 can be fixed, ensuring stability during operation.

[0041] This is because during operation, the forward and backward movement of the relay 20 relative to the carrier 10 may cause abnormal operation of the relay 20. In order to avoid this situation, the support vertical plate 50 on the carrier 10 can be connected to the side wall of the relay 20, thereby creating a certain obstruction to the relative movement of the relay 20, so that it can remain stationary on the carrier 10 to prevent functional abnormalities.

[0042] Since the battery energy distribution device 100 has multiple relays 20 , optionally, a supporting plate 50 can be provided at the corresponding position of each relay 20 , so as to fix the relay 20 at each position and fully ensure the effectiveness of the relay 20 .

[0043] Optionally, the support vertical plate 50 on the carrier 10 is perpendicular to the plane where the carrier 10 is located, so that the overall structure has better stability and meets the structural requirements of the relay 20.

[0044] As for the connection between the support plate 50 and the carrier 10, the two can be stamped and formed as one piece to form an integral structure, or the support plate 50 can be a split structure and fixedly connected to the carrier 10 through a welding process. It should be noted that the position of the support plate 50 needs to correspond to the position of the connected relay 20. The utility model does not specifically limit the specific number, position and forming process of the support plate 50.

[0045] An embodiment of the utility model provides a battery energy distribution device 100, which forms a connection with the relay 20 by arranging a supporting vertical plate 50 on the carrier 10, so as to further fix the relay 20 on the basis of ensuring that the docking port 40 of the relay 20 is facing the top, thereby preventing the relay 20 from malfunctioning after operation and forming a safety protection for the relay 20.

[0046] As an alternative embodiment, see Figure 3 and Figure 4 The battery energy distribution device 100 includes a reinforcement member 60 , which is connected between the carrier 10 and the support plate 50 , and the reinforcement member 60 is configured to abut against the support plate 50 on the carrier 10 .

[0047] After the support plate 50 is disposed on the carrier 10 , in order to further improve the structural strength of the support plate 50 , in this embodiment, a reinforcing member 60 is disposed between the carrier 10 and the support plate 50 to reinforce the support plate 50 .

[0048] This is mainly because after the relay 20 is connected to the support plate 50, the support plate 50 may fall over or fail due to the weak strength at the support plate 50 during operation. Therefore, a reinforcement member 60 is arranged between the support plate 50 and the carrier 10 to increase the structural strength at the position of the support plate 50 and provide reliable support for the support plate 50.

[0049] Optionally, the reinforcement 60 can be connected between the carrier 10 and the supporting vertical plate 50 through a welding process, thereby forming a fixed connection, thereby improving the connection strength between the structures. As for the specific structure of the reinforcement 60, the reinforcement 60 can adopt a plate-like structure or a block-like structure. The utility model does not specifically limit the specific structure of the reinforcement 60, and it is sufficient to improve the connection strength between the supporting vertical plate 50 and the carrier 10.

[0050] The embodiment of the utility model provides a battery energy distribution device 100, which provides a reinforcement member 60 between the carrier 10 and the support vertical plate 50, so that the reinforcement member 60 is used to form abutment against the support vertical plate 50, thereby improving the structural strength of the support vertical plate 50, providing support and protection for the support vertical plate 50, and preventing the failure of the connection with the relay 20 caused by the support vertical plate 50 tipping over, thereby having better structural characteristics.

[0051] As an optional embodiment, a connection hole 51 is provided on the support plate 50 , and the support plate 50 is bolted to the relay 20 through the connection hole 51 .

[0052] Optionally, the support plate 50 may be connected to the relay 20 by bolts, thereby facilitating installation and removal of the relay 20 and adjusting the position of the relay 20 .

[0053] Optionally, a connecting hole 51 is provided on the supporting plate 50, and there are usually multiple connecting holes 51. In this embodiment, the connecting holes 51 are arranged at the diagonal corners of the supporting plate 50 to form a stable bolt connection with the relay 20. The utility model does not specifically limit the specific position and number of the connecting holes 51 on the supporting plate 50, as long as they can form a stable connection with the relay 20.

[0054] An embodiment of the utility model provides a battery energy distribution device 100, which forms a bolt connection with the relay 20 by setting a connection hole 51 on the supporting plate 50. As a detachable connection method, it is conducive to the disassembly and assembly of the relay 20, improves the convenience and flexibility of the connection of the relay 20, and is also convenient for the maintenance of the relay 20.

[0055] As an alternative embodiment, see Figure 3 and Figure 4 At least one connecting hole 51 is arranged on a side of the supporting plate 50 close to the carrier 10, and a receiving groove 11 is arranged at a corresponding position of the connecting hole 51 close to the carrier 10. The opening of the receiving groove 11 is arranged toward the supporting plate 50, and the receiving groove 11 is configured to receive bolts at part of the connecting hole 51.

[0056] Considering that the actual structure of the bolt is that the bolt head has a relatively large size, when the connection hole 51 on the supporting plate 50 is set at the bottom of the supporting plate 50, after the bolt is inserted into the connection hole 51, its head will form a structural conflict with the bottom support member 10, which may easily cause a situation where the connection cannot be made.

[0057] Therefore, in this embodiment, a receiving groove 11 is provided on the carrier 10 corresponding to the connecting hole 51 near the bottom of the supporting plate 50. The receiving groove 11 opens upward and is mainly used to receive the head of the bolt. During and after the connection, the bolt can be partially received, making it easier to screw the bolt into the connecting hole 51. The receiving groove 11 on the carrier 10 provides a avoidance for the bolt, thereby preventing the carrier 10 from blocking the bolt structure and causing a connection failure.

[0058] The utility model does not impose any special restrictions on the opening size and structure of the receiving groove 11, which mainly depends on the size and shape of the bolt. The receiving groove 11 can be used to form a partial avoidance for the bolt to avoid structural conflict.

[0059] The embodiment of the utility model provides a battery energy distribution device 100, by arranging a receiving groove 11 on the carrier 10 at the corresponding position of the bottom of the connecting hole 51, so that the receiving groove 11 is used to avoid the bolts during the connection process between the supporting plate 50 and the relay 20, so that the structures can adapt to each other, and the bolt connection process of the relay 20 is convenient to realize, avoiding the connection failure problem caused by structural conflict.

[0060] As an alternative embodiment, see Figure 4 The battery energy distribution device 100 includes a spacer 70 , which is disposed between the carrier 10 and the relay 20 , and the spacer 70 supports the relay 20 .

[0061] Considering that when the docking port 40 is set on the top surface of the relay 20, the center of gravity of the relay 20 is downward and tilted, a cushioning member 70 is set between the carrier 10 and the relay 20 in this embodiment, so that the cushioning member 70 is used to support the relay 20, thereby alleviating functional abnormalities caused by the unstable center of gravity of the relay 20.

[0062] Optionally, the raising member 70 can be a block structure with higher bearing strength. The raising member 70 is arranged on the supporting member 10 and can be stamped integrally with the supporting member 10. Of course, the raising member 70 can also be a split structure, which is fixedly connected with the supporting member 10 through a welding process. The utility model does not specifically limit the specific structure and molding process of the raising member 70.

[0063] An embodiment of the utility model provides a battery energy distribution device 100, which supports the relay 20 by arranging a cushioning member 70 on the carrier 10, so that the docking port 40 at the relay 20 faces upward, thereby overcoming the functional abnormality caused by the center of gravity offset of the relay 20, and providing reliable guarantee for the normal operation of the relay 20.

[0064] As an alternative embodiment, see Figure 4 The padding member 70 is provided with a through hole 71 , and the through hole 71 runs through the padding member 70 , and the through hole 71 is configured to reduce the weight of the padding member 70 .

[0065] Optionally, the through hole 71 provided on the raising member 70 may be a weight-reducing hole, thereby reducing the weight of the entire structure, reducing the overall load on the bearing member 10 , and satisfying the lightweight design of the structure.

[0066] The through hole 71 provided on the pad 70 can be integrally formed during the stamping process. The shape of the through hole 71 is a rounded hole under the influence of the actual process. The utility model does not specifically limit the specific size and shape of the through hole 71.

[0067] The provision of the through hole 71 not only plays a certain role in reducing weight, but also has a certain avoidance effect, since the battery energy distribution device 100 also includes multiple low-voltage wiring harnesses and other lines, allowing multiple complex lines to pass through, thereby facilitating the connection between components.

[0068] The embodiment of the utility model provides a battery energy distribution device 100, which is helpful to reduce the weight of the overall structure and the load on the bearing member 10 on the basis of overcoming the center of gravity offset of the relay 20 by setting a through hole 71 penetrating the raising member 70, thereby having better safety and stability.

[0069] As an alternative embodiment, see Figure 5 The battery energy distribution device 100 includes a packaging shell 80, which covers the relay 20 and the power connection line 30 and is connected to the carrier 10. The packaging shell 80 includes a plug interface 81 arranged corresponding to the docking port 40. The docking port 40 is exposed at the plug interface 81. In the direction from the relay 20 to the packaging shell 80, the opening size of the plug interface 81 gradually increases.

[0070] In order to isolate and protect the relay 20 and the power connection line 30 and prevent the internal electrical connection from being disturbed and affected by the outside world, in this embodiment, a packaging shell 80 is provided to cover the internal components, thereby forming safety protection.

[0071] Since the docking port 40 at the relay 20 is set at the top and this position needs to be electrically connected to an external electrical device, a plug-in interface 81 corresponding to the docking port 40 is set at the corresponding position of the top surface of the packaging shell 80, so that the internal docking port 40 is exposed at the plug-in interface 81, which facilitates the completion of the plug-in with the docking port 40.

[0072] Optionally, the number and position of the plug ports 81 on the packaging shell 80 can be set according to the actual number of relays 20 inside and the number of docking ports 40 provided to ensure that each relay 20 can be plugged in, and the plug ports 81 can also be correspondingly set as square ports.

[0073] In order to further facilitate the staff to complete the plugging of the relay 20, the plugging port 81 on the packaging shell 80 is recessed, and the opening size of the plugging port 81 toward the outside is gradually increased, thereby providing a larger plugging space for the staff, making it easier to reach into the plugging port 81 to complete the plugging operation.

[0074] The plug-in port 81 provided in this embodiment is an outward expansion structure with a gradually increasing opening. There is no special limitation on the specific size of the opening expansion, and it only needs to provide sufficient operating space for the staff.

[0075] The embodiment of the utility model provides a battery energy distribution device 100, which provides a plug-in port 81 corresponding to the docking port 40 on the packaging shell 80, while isolating and protecting the internal relay 20 and the power connection line 30, and also completes the top plug-in of the relay 20. At the same time, by gradually increasing the opening size of the plug-in port 81, sufficient plug-in space is provided for the staff, making it easier to complete the plug-in operation of the relay 20, and further improving the convenience of plugging and unplugging.

[0076] As an alternative embodiment, see Figure 6 The battery energy distribution device 100 includes a support member 90, which is arranged on the side of the carrier 10 away from the relay 20. The support member 90 has a protrusion 91 protruding toward the carrier 10, and the carrier 10 has a recessed portion 12 corresponding to the protrusion 91. The recessed portion 12 covers the protrusion 91 to connect the carrier 10 with the support member 90.

[0077] Optionally, the support member 90 may also be a plate-shaped structure, and the support member 90 is disposed at the bottom of the carrier 10 and connected to the carrier 10 .

[0078] The support member 90 in this embodiment is provided with a plurality of protrusions 91, and correspondingly, the carrier 10 is provided with a plurality of recesses 12 corresponding to the protrusions 91. The protrusions 91 and the recesses 12 are connected to each other, and the support member 90 provides overall support for the carrier 10 and its components.

[0079] Optionally, a rivet nut may be provided at a corresponding position of the raised portion 91 , and a corresponding bolt hole may be provided on the recessed portion 12 , so that the raised portion 91 and the recessed portion 12 may be bolted together, thereby forming a detachable connection between the support member 90 and the carrier member 10 .

[0080] The specific recessed height of the recessed portion 12 determines the sinking height of the relay 20. Optionally, by docking the recessed portion 12 with the raised portion 91, the overall structure can be sunk by 10-15 mm, thereby reducing the overall height of the battery energy distribution device 100 and saving space in the height direction of the battery pack.

[0081] The embodiment of the utility model provides a battery energy distribution device 100, which forms a docking fit with a recessed portion 12 on a carrier 10 by arranging a protrusion 91 on the support member 90, so that the overall structure can achieve a sinking effect, thereby reducing the height of the overall structure and saving a certain amount of space inside the battery pack.

[0082] According to an embodiment of the utility model, a battery is provided, comprising the battery energy distribution device 100 as described above.

[0083] The embodiment of the utility model provides a battery energy distribution device and a battery, by arranging a relay on a carrier and arranging a docking port at an end of the relay away from the carrier, and utilizing the docking port to form an electrical connection with an external electrical device, thereby arranging the docking port on the top surface of the relay, so that a worker can perform top plugging of the relay, avoiding the side plugging of the relay in the prior art, and preventing the problem of inconvenience in plugging due to space limitations in the battery pack, so that there is a larger operating space during the process of plugging the relay, thereby improving the operating convenience of the worker, facilitating the connection operation of the relay, and being unaffected by the space around the battery energy distribution device, and having better connection performance.
