Technical Field

[0001] This application relates to the field of power battery technology, specifically to a battery pack housing, a battery pack, and a vehicle. Background Technology

[0002] Currently, battery pack cooling structures are mainly classified into profile-type cold plates, stamped and brazed cold plates, and harmonica-type cold plates. Among them, profile-type cold plates are widely used as structural components to enhance the strength of battery packs. However, due to structural limitations, the liquid inlet and outlet of profile-type cold plates can only be located on both sides of the cold plate, which restricts the layout design of battery pack components and poses a significant risk of battery pack failure. Utility Model Content

[0003] In view of this, this application provides a battery pack housing that allows the inlet and outlet to be located on the same side of the cold plate as needed. This not only frees up space on the other side of the cold plate, providing flexible layout space for components such as busbars, sensors, and electrical connectors, but also allows the cooling pipes connected to the inlet and outlet to be centrally located on the other side of the cold plate, reducing the crossing and tangling of cooling pipes inside the battery pack and lowering the risk of battery pack failure due to space constraints. Furthermore, this application also provides a battery pack including the aforementioned battery pack housing, and a vehicle including the aforementioned battery pack.

[0004] The battery pack housing of this application includes a cold plate and an adapter assembly. The cold plate has a flow channel and a first port and a second port communicating with the flow channel. The first port and the second port are arranged at intervals along a first direction, which is perpendicular to the thickness direction of the cold plate. The adapter assembly includes a first tube, a second tube, and an adapter pipe. At least a portion of the adapter pipe extends along the first direction. One end of the first tube forms a first interface, and the other end of the first tube is connected to the first port through the adapter pipe. One end of the second tube forms a second interface, and the other end of the second tube is connected to the second port. One of the first interface and the second interface is a liquid inlet, and the other is a liquid outlet.

[0005] Optionally, the battery pack housing also includes a frame, which is connected to the edge of the cold plate and forms a receiving cavity. The first port, the second port and the adapter pipe are all located inside the receiving cavity. The frame is provided with a first hole and a second hole. The first interface passes through the first hole and extends out of the receiving cavity, and the second interface passes through the second hole and extends out of the receiving cavity.

[0006] Optionally, the adapter pipe includes a first adapter section extending along the thickness direction of the cold plate and a second adapter section extending along a first direction. One end of the first adapter section is connected to one end of the second adapter section, the other end of the first adapter section is connected to a first port, and the other end of the second adapter section is connected to a first pipe.

[0007] Optionally, the adapter pipe further includes a first connecting block, through which the first adapter segment and the second adapter segment are connected.

[0008] Optionally, the second pipe includes a first connecting segment extending along the thickness direction of the cold plate and a second connecting segment extending along a second direction. One end of the first connecting segment and one end of the second connecting segment are connected, the other end of the first connecting segment is connected to a second port, and the other end of the second connecting segment forms a second interface. The second direction is perpendicular to the thickness direction of the cold plate and the first direction.

[0009] Optionally, the second pipe further includes a second connecting block, through which the first connecting segment is connected to the second connecting segment.

[0010] Optionally, the adapter assembly also includes an adapter block, through which the first pipe is connected to the adapter tube.

[0011] Optionally, in the first direction, the transfer pipe is disposed between the first port and the second port, and the first pipe is disposed between the transfer pipe and the second port.

[0012] The battery pack of this application includes a battery pack housing and battery cells, wherein the battery pack housing is any of the aforementioned battery pack housings; and the battery cells are disposed within the battery pack housing.

[0013] The vehicle described in this application includes any of the battery packs mentioned above.

[0014] In this embodiment of the battery pack housing, the first and second openings of the cold plate are arranged at intervals along a first direction, such that the two ends of the flow channel are respectively connected to the first and second openings. By providing a connecting assembly including a first pipe, a second pipe, and a connecting pipe, and setting the connecting pipe to extend at least partly along the first direction, the relative positions of the first interface of the first pipe and the second interface of the second pipe, i.e., the relative positions of the inlet and outlet, are not limited by the relative positions of the first and second openings. Thus, the inlet and outlet can be set on the same side of the cold plate as needed, thereby not only freeing up space on the other side of the cold plate to provide flexible layout space for components such as busbars, sensors, and electrical connectors, which is especially suitable for high-density integrated battery pack designs; but also allowing the cooling pipes connected to the inlet and outlet to be concentrated on the other side of the cold plate, reducing the crossing and entanglement of cooling pipes inside the battery pack, and reducing the risk of battery pack failure due to space congestion, such as the cooling pipes being squeezed or a short circuit occurring inside the battery pack.

[0029] In related technologies, profile-type cold plates include flow channels, inlets, and outlets, with the inlets and outlets connected to the outlet and inlet of the flow channels, respectively. In practical use, coolant enters through the inlet, flows along the flow channels within the cold plate, and finally exits through the outlet. Since the inlet and outlet of the flow channels are located on opposite sides of the cold plate, the inlet and outlet are located on opposite sides of the cold plate. This results in cooling pipes being installed on both sides of the battery pack, which is detrimental to the arrangement of battery pack circuit components, such as the layout design of the input and output busbars. The cooling pipes are the pipes that allow coolant to flow in and out.

[0030] This application provides a battery pack housing. By setting a connecting pipe that connects the liquid inlet and the cold plate, or setting a connecting pipe that connects the liquid outlet and the cold plate, the position of the liquid inlet and / or the liquid outlet connected to the cold plate can be changed, so that the liquid inlet and the liquid outlet can be located on the same side of the cold plate, freeing up space on the other side of the cold plate and improving the layout flexibility of the battery pack components.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] refer to Figures 1 to 4 The battery pack housing provided in this application includes a cold plate 1 and a connecting assembly 2. The cold plate 1 is provided with a flow channel 11 and a first port 12 and a second port 13 communicating with the flow channel 11. The first port 12 and the second port 13 are arranged at intervals along a first direction, which is perpendicular to the thickness direction of the cold plate 1. The connecting assembly 2 includes a first tube 21, a second tube 22 and a connecting tube 23. At least a portion of the connecting tube 23 extends along the first direction. One end of the first tube 21 forms a first interface 211, and the other end of the first tube 21 is connected to the first port 12 through the connecting tube 23. One end of the second tube 22 forms a second interface 221, and the other end of the second tube 22 is connected to the second port 13. One of the first interface 211 and the second interface 221 is a liquid inlet and the other is a liquid outlet.

[0033] Wherein, at least a portion of the transfer pipe 23 extends along the first direction, which can be understood as: the transfer pipe 23 includes only one pipe segment, and the entire transfer pipe 23 extends along the first direction; or, the transfer pipe 23 includes at least two pipe segments, and the extension directions of the two pipe segments intersect, with at least one pipe segment extending along the first direction. By setting at least a portion of the transfer pipe 23 to extend along the first direction, when the first pipe 21 is connected to the first port 12 through the transfer pipe 23, the position of the first pipe 21 in the first direction is not limited by the position of the first port 12, that is, the position of the first pipe 21 in the first direction can be different from the position of the first port 12 in the first direction, thereby allowing the position of the first pipe 21 in the first direction to be designed as needed.

[0034] In use, when the battery pack housing of this embodiment is in use, and the first interface 211 forms an inlet and the second interface 221 forms an outlet, the coolant enters the first pipe 21 through the first interface 211, then enters the flow channel 11 of the cold plate 1 through the adapter pipe 23 via the first port 12, then flows along the flow channel 11 to the second port 13, and finally flows out through the second interface 221 of the second pipe 22. When the second interface 221 forms an inlet and the first interface 211 forms an outlet, the coolant enters the second pipe 22 through the second interface 221, then enters the flow channel 11 of the cold plate 1 through the second port 13, then flows along the flow channel 11 to the first port 12, then flows into the adapter pipe 23, and finally flows out through the first interface 211 of the first pipe 21.

[0035] In this embodiment of the battery pack housing, the first port 12 and the second port 13 of the cold plate 1 are arranged at intervals along a first direction, such that the two ends of the flow channel 11 are respectively connected to the first port 12 and the second port 13. By providing a connecting assembly 2 including a first pipe 21, a second pipe 22 and a connecting pipe 23, and setting the connecting pipe 23 to extend at least partly along the first direction, after the first pipe 21 is connected to the first port 12 through the connecting pipe 23 and the second pipe 22 is connected to the second port 13, the relative positions of the first interface 211 of the first pipe 21 and the second interface 221 of the second pipe 22, that is, the relative positions of the liquid inlet and the liquid outlet, are not limited by the relative positions of the first port 12 and the second port 13. Therefore, the inlet and outlet can be set on the same side of the cold plate 1 as needed. This not only frees up space on the other side of the cold plate 1, providing flexible layout space for components such as busbars, sensors, and electrical connectors, which is especially suitable for high-density integrated battery pack designs, but also allows the cooling pipes connected to the inlet and outlet to be centrally located on the other side of the cold plate 1. This reduces the crossing and tangling of cooling pipes inside the battery pack, and lowers the risk of battery pack failure due to space congestion, such as the cooling pipes being squeezed or a short circuit occurring inside the battery pack.

[0036] The cold plate 1 can be a profile-type cold plate 1. When the first interface 211 is the liquid inlet and the second interface 221 is the liquid outlet, the first port 12 of the cold plate 1 is the coolant inlet of the cold plate 1, and the second port 13 of the cold plate 1 is the coolant outlet of the cold plate 1.

[0037] In some embodiments, such as Figures 3 to 8 As shown, in the first direction, the transfer pipe 23 is disposed between the first port 12 and the second port 13, and the first pipe 21 is disposed between the transfer pipe 23 and the second port 13.

[0038] By designing the positions of the adapter pipe 23, the first port 12, and the second port 13 as described above, the first pipe 21 is connected to the first port 12 via the adapter pipe 23, and the second pipe 22 is connected to the second port 13. This allows the first pipe 21 to be positioned close to the second pipe 22, enabling the first pipe 21 and the second pipe 22 to be located on the same side of the cold plate 1 in the first direction. This allows other components (such as circuit assemblies) to be arranged on the other side of the cold plate 1, facilitating the layout design of the battery pack.

[0039] To make the technical solution of this application easier to understand, the following description further illustrates the technical solution of this application, taking the thickness direction of the cold plate 1 as being consistent with the vertical direction and the first direction as being consistent with the horizontal direction. The vertical and horizontal directions are shown in the figure.

[0040] For example, such as Figures 4 to 6 As shown, the adapter pipe 23 is located to the right of the first port 12, the second port 13 is located to the right of the adapter pipe 23, the first pipe 21 is located to the right of the adapter pipe 23, and the second pipe 22 is located to the right of the adapter pipe 23. This arrangement ensures that both the first pipe 21 and the second pipe 22 are located close to the right side of the cold plate 1, meaning that by setting the adapter pipe 23, the first pipe 21 can be positioned to the right.

[0041] In some embodiments, such as Figures 3 to 6 As shown, the adapter assembly 2 also includes an adapter block 24, through which the first pipe 21 is connected to the adapter pipe 23.

[0042] By setting up the adapter block 24, the connection area between the first pipe 21 and the adapter pipe 23 can be increased, the connection reliability between the first pipe 21 and the adapter pipe 23 can be improved, the risk of coolant leakage from the connection between the first pipe 21 and the adapter pipe 23 can be reduced, and the reliability of the battery pack housing can be improved.

[0043] Optionally, the adapter block 24 is integrally formed with the first pipe 21, and the adapter block 24 is welded to the adapter pipe 23. For example, the adapter block 24 and the first pipe 21 are formed by machining.

[0044] In other embodiments, the adapter block 24 may be integrally formed with the adapter pipe 23, and the adapter block 24 may be welded to the first pipe 21. Alternatively, both the adapter pipe 23 and the first pipe 21 may be welded to the adapter block 24.

[0045] In related technologies, when the cold plate 1 connects to the outside of the battery pack housing, an adapter is required. For example, the frame 3 has an adapter hole, the cold plate 1 is connected to the frame 3 of the housing via a pipe, and the adapter is connected to the frame 3 of the housing to achieve the connection between the cold plate 1 and the adapter. This not only results in a large number of parts in the battery pack housing, affecting the assembly efficiency of the battery pack housing, but also leads to the risk of coolant leakage inside the battery pack housing, affecting the safety of the battery pack.

[0046] In some embodiments, such as Figure 3 and Figure 7 As shown, the battery pack housing also includes a frame 3, which is connected to the edge of the cold plate 1 and forms a receiving cavity 4. The first opening 12, the second opening 13, and the adapter pipe 23 are all located within the receiving cavity 4. The frame 3 has a first hole 31 and a second hole 32. The first interface 211 passes through the first hole 31 and extends out of the receiving cavity 4, and the second interface 221 passes through the second hole 32 and extends out of the receiving cavity 4. The receiving cavity 4 can be used to house battery cells, and the cold plate 1 serves as the base plate of the battery pack housing.

[0047] For example, the cold plate 1 is a rectangular plate, and the frame 3 includes a front frame 301, a rear frame 302, a left frame 303, and a right frame 304. The front frame 301 is connected to the front edge of the cold plate 1, the rear frame 302 is connected to the rear edge of the cold plate 1, the left frame 303 is connected to the left edge of the cold plate 1, and the right frame 304 is connected to the right edge of the cold plate 1, so that the cold plate 1, the front frame 301, the rear frame 302, the left frame 303, and the right frame 304 form an upward-opening receiving cavity 4. The first hole 31 and the second hole 32 can be provided on the front frame 301, so that both the first interface 211 and the second interface 221 extend forward from the front side of the battery pack housing.

[0048] By placing the first port 12, the second port 13, and the adapter pipe 23 inside the receiving cavity 4, the frame 3 can protect the adapter pipe 23, preventing it from being exposed outside the receiving cavity 4 and being damaged, thereby improving the reliability of the battery pack's thermal management system and enhancing the safety of the battery pack.

[0049] Furthermore, the first interface 211 extends out of the receiving cavity 4 through the first hole 31, and the second interface 221 extends out of the receiving cavity 4 through the second hole 32. The first interface 211 and the second interface 221 can be directly connected to the cooling pipes, thus connecting the cooling pipes to the cold plate 1. This eliminates the need for additional adapters connecting the cooling pipes and the first interface 211, and also eliminates the need for additional connectors connecting the cooling pipes and the second interface 221. Therefore, the number of adapters can be reduced, lowering the risk of coolant leakage, especially reducing the risk of coolant leakage within the battery pack housing, and improving the safety of the battery pack.

[0050] In other embodiments, such as Figure 9 As shown, the first tube 21, the second tube 22, and the adapter tube 23 are all located outside the receiving cavity 4. In this case, it is not necessary to provide the first hole 31 and the second hole 32 in the frame 3. However, the adapter tube 23 is located inside the receiving cavity 4, and it loses the protective function of the frame 3, making it prone to damage.

[0051] In some embodiments, such as Figures 4 to 6 As shown, the adapter pipe 23 includes a first adapter section 231 extending along the thickness direction of the cold plate 1 and a second adapter section 232 extending along a first direction. One end of the first adapter section 231 is connected to one end of the second adapter section 232, the other end of the first adapter section 231 is connected to the first port 12, and the other end of the second adapter section 232 is connected to the first pipe 21.

[0052] For example, the first transition section 231 extends in the vertical direction, the upper end of the first transition section 231 is connected to the left end of the second transition section 232, the lower end of the first transition section 231 is connected to the first port 12, and the right end of the second transition section 232 is connected to the first pipe 21.

[0053] By configuring the adapter pipe 23 to include a first adapter section 231 and a second adapter section 232, with the first adapter section 231 and the second adapter section 232 extending along the thickness direction and the first direction of the cold plate 1 respectively, it is convenient to use the adapter pipe 23 to connect the first port 12 and the first pipe 21.

[0054] Optionally, the first transition section 231 and the second transition section 232 are separately provided, and the first transition section 231 and the second transition section 232 are welded together. The first transition section 231 is welded to the first port 12, and the second transition section 232 is welded to the first pipe 21.

[0055] In some embodiments, such as Figures 4 to 6 As shown, the adapter pipe 23 also includes a first connecting block 25, and the first adapter segment 231 and the second adapter segment 232 are connected through the first connecting block 25.

[0056] By setting the first connecting block 25 and connecting the first adapter section 231 and the second adapter section 232, the connection area between the first adapter section 231 and the second adapter section 232 can be increased, the connection reliability of the first adapter section 231 and the second adapter section 232 can be improved, the risk of coolant leakage from the connection between the first pipe 21 and the adapter pipe 23 can be reduced, and the reliability of the battery pack housing can be improved.

[0057] Optionally, the first connecting block 25 and the first transition section 231 are integrally formed, and the second transition section 232 is welded to the first connecting block 25. For example, the first connecting block 25 and the first transition section 231 are formed by machining.

[0058] In other embodiments, the first connecting block 25 may be integrally formed with the second transition segment 232, and the transition block 24 may be welded to the first transition segment 231. Alternatively, both the first transition segment 231 and the second transition segment 232 may be welded to the first connecting block 25.

[0059] In some embodiments, the second tube 22 includes a first connecting segment 223 extending along the thickness direction of the cold plate 1 and a second connecting segment 224 extending along a second direction. One end of the first connecting segment 223 is connected to one end of the second connecting segment 224, the other end of the first connecting segment 223 is connected to the second port 13, and the other end of the second connecting segment 224 forms a second interface 221. The second direction is perpendicular to the thickness direction of the cold plate 1 and the first direction.

[0060] By configuring the second tube 22 to include a first connecting section 223 and a second connecting section 224, and the first connecting section 223 and the second connecting section 224 extending along the thickness direction and the second direction of the cold plate 1 respectively, it is convenient for the second tube 22 to be connected to the second port 13.

[0061] To make the technical solution of this application easier to understand, the technical solution of this application will be further described below using the example of the second direction being consistent with the front and rear directions.

[0062] like Figure 4 and Figure 6 As shown, the first connecting segment 223 extends in the vertical direction, the second connecting segment 224 extends in the front-back direction, the upper end of the first connecting segment 223 is connected to the rear end of the second connecting segment 224, the lower end of the first connecting segment 223 is connected to the second port 13, and the front end of the second connecting segment 224 forms the second interface 221.

[0063] In some embodiments, such as Figure 4 and Figure 6 As shown, the second pipe 22 also includes a second connecting block 222, and the first connecting segment 223 is connected to the second connecting segment 224 through the second connecting block 222.

[0064] By setting a second connecting block 222 to connect the first connecting segment 223 and the second connecting segment 224, the connection area between the first connecting segment 223 and the second connecting segment 224 can be increased, the connection reliability of the first connecting segment 223 and the second connecting segment 224 can be improved, the risk of coolant leakage from the connection between the first connecting segment 223 and the second connecting segment 224 can be reduced, and the reliability of the battery pack housing can be improved.

[0065] Optionally, the second connecting block 222, the first connecting segment 223, and the second connecting segment 224 are integrally formed, for example, the second connecting block 222, the first connecting segment 223, and the second connecting segment 224 are formed by machining.

[0066] In other embodiments, the second connecting block 222 may be integrally formed with the first connecting segment 223, and the first connecting segment 223 may be welded to the second connecting block 222; or, the second connecting block 222 may be integrally formed with the second connecting segment 224, and the first connecting segment 223 may be welded to the second connecting block 222; or, both the first connecting segment 223 and the second connecting segment 224 may be welded to the second connecting block 222.

[0067] In some embodiments, the first tube 21 is sealed to the first hole 31, and the second tube 22 is sealed to the second hole 32.

[0068] For example, the outer peripheral surface of the first pipe 21 is welded to the first hole 31 to achieve a seal between the first pipe 21 and the first hole 31. The outer peripheral surface of the second pipe 22 is welded to the second hole 32 to achieve a seal between the second pipe 22 and the second hole 32.

[0069] By sealing the first tube 21 to the first hole 31, not only is a seal achieved at the first hole 31, but the first tube 21 is also connected to the frame 3, improving the stability of the first tube 21. Similarly, by sealing the second tube 22 to the second hole 32, not only is a seal achieved at the second hole 32, but the second tube 22 is also connected to the frame 3, improving the stability of the second tube 22. This further enhances the reliability of the battery pack housing.

[0070] In some embodiments, at least one of the transition block 24, the first connecting block 25, and the second connecting block 222 forms a limiting block, which engages with the front frame 301. For example, the front end face of the limiting block abuts against the front frame 301, thereby limiting the position of the front frame 301 in the front-rear direction.

[0071] The manufacturing method of the battery pack housing according to an embodiment of this application:

[0072] Connect the first pipe 21, the adapter block 24 and the adapter pipe 23 to form a connection assembly;

[0073] Connect the adapter pipe 23 of the connecting assembly to the first port 12 of the cold plate 1, and at the same time connect the second pipe 22 to the second port 13 of the cold plate 1.

[0074] The first tube 21 and the second tube 22 are passed through the first hole 31 and the second hole 32 of the front frame 301 respectively, and then the front frame 301 is connected to the front edge of the cold plate 1.

[0075] Connect the rear frame 302, left frame 303, and right frame 304 to the rear edge, left edge, and right edge of the cold plate 1, respectively.

[0076] Alternatively, the adapter pipe 23 can be connected to the first port 12 of the cold plate 1 first, then the adapter block 24 can be connected to the adapter pipe 23, and then the first pipe 21 can be connected to the adapter block 24 to achieve the connection between the connecting component and the cold plate 1. Alternatively, the rear frame 302, left frame 303 and right frame 304 can be connected to the rear edge, left edge and right edge of the cold plate 1 respectively first, and then the front frame 301 can be connected to the front edge of the cold plate 1.

[0077] The battery pack provided in this application includes a battery pack housing and battery cells. The battery pack housing is any of the battery pack housings described above, and the battery cells are disposed inside the battery pack housing.

[0078] The battery cells are multiple, and multiple battery cells can form multiple battery modules. The battery modules are set in the receiving cavity 4.

[0079] In this embodiment of the battery pack housing, the adapter component 2 is configured to include an adapter pipe 23. The adapter pipe 23 allows the relative positions of the inlet and outlet to be unrestricted by the relative positions of the first opening 12 and the second opening 13 of the cold plate 1, thus enhancing the application scenarios of the profiled cold plate 1 and better meeting user needs. Furthermore, the positions of the inlet and outlet can be flexibly arranged as needed, making their layout more flexible and improving the thermal management capabilities of the battery pack. By passing the first interface 211 of the first pipe 21 through the first hole 31 of the frame 3 and the second opening 13 of the second pipe 22 through the second hole 32 of the frame 3, the need for additional adapters connecting the cooling pipes is eliminated, reducing the risk of coolant leakage within the battery pack housing and improving the reliability of the battery pack housing. By placing the adapter pipe 23 within the receiving cavity 4 of the battery pack housing, the frame 3 can protect the adapter pipe 23, preventing damage to the adapter pipe 23 and thus affecting the thermal management system of the battery pack. In addition, the cold plate 1 also serves as the bottom plate of the battery pack housing and connects with the frame 3, which improves the structural strength of the battery pack housing and facilitates the lightweight design of the battery pack housing.
