DETAILED DESCRIPTION

[0029] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0030] The embodiments described in some embodiments of the present disclosure below do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0031] like Figures 1 to 7 As shown, an exemplary embodiment of the present disclosure provides a battery pack cold plate 100. The battery pack cold plate 100 is used to support the power distribution and battery cells 300, and can exchange heat with the battery cells 300, thereby dissipating heat from the battery pack. Under certain operating conditions, such as large temperature differences or high humidity, water vapor in the battery pack is easily gathered and condensed into condensed water. If the condensed water cannot be processed in time, it is easy to cause problems such as insulation short circuits, posing a hidden danger to driving safety.

[0032] To this end, the battery pack cold plate provided by the present disclosure is provided with a liquid absorbing member 13. The liquid absorbing member 13 may be, for example, a desiccant. Specifically, the battery pack cold plate 100 is provided with an opening 123, and the liquid absorbing member 13 partially extends from the opening 123 into the upper surface of the battery pack cold plate 100, and the lower surface of the battery pack cold plate 100 is detachably provided with a mounting member 14, and the liquid absorbing member 13 is arranged on the mounting member 14.

[0033] Among them, the upper surface of the battery pack cold plate 100 is used to support the surface of the power distribution and battery cells 300, and the lower surface of the battery pack cold plate 100 is the other side surface opposite to the upper surface. The liquid absorbent 13 can be set in a place where condensed water is more likely to gather. The battery pack cold plate is provided with an opening 123 to facilitate the installation of the liquid absorbent 13, and the liquid absorbent 13 is partially extended from the opening 123 to the upper surface of the battery pack cold plate 100. In some related technologies, the liquid absorbent 13 is usually directly installed inside the battery compartment as a whole. Considering that the liquid absorbent 13 such as desiccant is a consumable and has a limited ability to absorb liquid, it will not be able to continue to absorb liquid if it reaches a saturated state. If the liquid absorbent 13 is directly set in the battery compartment as in the related technology, when replacing and repairing the liquid absorbent 13, it is necessary to remove most of the battery pack structure to expose the internal structure of the battery compartment 220 before the liquid absorbent 13 can be further removed.

[0034] The present disclosure utilizes the mounting member 14 to indirectly mount the liquid absorbent member 13 inside the battery compartment, that is, the lower surface of the battery pack cold plate 100 is detachably provided with the mounting member 14, and the liquid absorbent member 13 is disposed on the mounting member 14. The liquid absorbent member 13 can be configured to be partially exposed from the lower surface of the battery pack cold plate 100, or the liquid absorbent member 13 can be flush with the lower surface of the battery pack cold plate 100, or the liquid absorbent member 13 can be located inside the opening 123, and can mainly be connected to the mounting member 14. In addition, the liquid absorbent member 13 can be integrally provided with the mounting member 13, or the liquid absorbent member 13 can be detachably connected to the mounting member 13, for example, the liquid absorbent member 13 and the mounting member 14 can be integrated into a module by bonding, welding or threaded connection.

[0035] Since the liquid absorbent member 13 is indirectly mounted on the battery pack cold plate 100 through the mounting member 14, when the liquid absorbent member 13 needs to be replaced and repaired, it is only necessary to remove the protective plate 400 arranged at the bottom of the battery pack cold plate 100 to expose the mounting member 14, and then remove the mounting member 14 together with the integrated liquid absorbent member 13 from the bottom of the battery pack, thereby eliminating the need to remove the battery pack to expose the internal structure of the battery compartment 220, and facilitating disassembly and assembly, thereby improving work efficiency.

[0036] The technical solution provided by the embodiment of the present disclosure may include the following beneficial effects: the battery pack cold plate 100 is provided with an opening 123, the liquid absorbent member 13 partially extends from the opening 123 into the upper surface of the battery pack cold plate 100, the lower surface of the battery pack cold plate 100 is detachably provided with a mounting member 14, and the liquid absorbent member 13 is arranged on the mounting member 13. Among them, the portion of the liquid absorbent member 13 extending into the upper surface of the battery pack cold plate 100 is used to absorb the condensed water accumulated in the battery pack, and the liquid absorbent member 13 is indirectly installed with the battery pack cold plate 100 through the mounting member 14 arranged on the lower surface of the battery pack cold plate 100, so that when the absorption capacity of the liquid absorbent member 13 is saturated, it is only necessary to remove the protective plate 400 at the bottom of the battery pack, and take out the mounting member 14 together with the liquid absorbent member 13 from the bottom, without disassembling the entire battery pack, thereby achieving the purpose of replacing and repairing the liquid absorbent member 13 more conveniently and quickly.

[0037] In order to prevent the accumulated condensed water from leaking from the possible gap between the opening 123 and the liquid absorbent member 13, a sealing structure may be provided at the opening 123. Figure 2 As described above, a first sealing member 15 may be provided between the mounting member 14 and the lower surface of the battery pack cold plate 100. At this time, the mounting member 14 may function as a pressure plate to press the first sealing member 15 against the lower surface of the battery pack cold plate 100. The first sealing member 15 may be, for example, a sealing foam, the shape and size of which may be adapted to the mounting member 14, and the first sealing member 15 may be provided with a hole for the liquid absorbing member 13 to pass through.

[0038] In other embodiments, while referring to Figure 3 and Figure 4 The mounting member 14 is detachably connected to the plate body of the battery pack cold plate 100 through a threaded connector 16, and a second sealing member 17 is provided between the threaded connector 16 and the lower surface of the battery pack cold plate 100. The threaded connector 16 may be, for example, a rivet nut, the column head of which is located on one side of the lower surface of the battery pack cold plate 100, and the second sealing member 17 is provided between the column head and the lower surface of the battery pack cold plate 100, the purpose of which is to prevent the accumulated condensed water from leaking from the hole into which the threaded connector 16 extends. The second sealing member 17 may be, for example, a sealing rubber ring.

[0039] According to the embodiments provided by the present disclosure, Figure 5As shown, the battery pack cold plate 100 may also be provided with a guide groove 12, the groove bottom of the guide groove 12 is configured to be inclined relative to the bottom surface of the battery pack cold plate 100, and the liquid absorbent member 13 is arranged at the lower end of the guide groove 12. That is, in this embodiment, the battery pack cold plate 100 provided by the present disclosure is provided with a guide groove 12 on the basis of the aforementioned liquid absorbent member 13, and the condensed water accumulated in the battery pack can flow in the guide groove 12. And the groove bottom of the guide groove 12 is configured to be inclined relative to the bottom surface of the battery pack cold plate 100, so that even when the vehicle is in a stationary state, the condensed water can spontaneously gather to the lower end of the guide groove 12 under the action of gravity, and then be absorbed by the liquid absorbent member 13 arranged at the lower end of the guide groove 12.

[0040] The liquid absorbent 13 can be set at a position that can produce a large temperature difference so that condensed water can be easily accumulated. In some embodiments, the battery pack cold plate 100 includes a first cold plate area 110 and a second cold plate area 120 arranged along a first direction, wherein the first cold plate area 110 is suitable for supporting power distribution, the second cold plate area 120 is suitable for supporting the battery cell 300, and the lower end of the guide groove 12 extends to the first cold plate area 110. The first cold plate area 110 corresponds to the position of the power distribution compartment 210 of the battery pack, and the second cold plate area 120 corresponds to the position of the battery compartment 220 of the battery pack. Specifically, the inlet and outlet water pipes of the battery pack cold plate 100 are passed through the first cold plate area 110. Considering the large temperature difference at the inlet and outlet water pipes, the temperature difference is caused by the low inlet water temperature and the high outlet water temperature, which makes it easier to gather and produce condensed water. Therefore, the present disclosure sets the liquid absorbent 13 at a position near the inlet and outlet, that is, the position of the first cold plate area 110 corresponding to the power distribution compartment 210. In other locations where a large temperature difference can be generated, for example, the locations of the poles at both ends of the battery cell 300 , the liquid absorbent member 13 may also be provided, or the condensed water may be guided to the location where the liquid absorbent member 13 is provided through the guide groove 12 .

[0041] Furthermore, if Figure 5 As shown, the battery pack cold plate 100 includes a cold plate body 11 in which a cooling medium is provided, and a guide groove 12 is arranged around the cold plate body 11. This method of arranging the guide groove 12 on the periphery of the cold plate body 11 is conducive to avoiding the problem of reducing the cooling area due to the arrangement of the guide groove 12 inside the cold plate body 11. Specifically, the guide groove 12 includes a guide section 121 extending along a first direction and a confluence section 122 extending along a second direction. As shown in the figure, the extension directions of the first direction and the second direction are perpendicular to each other, wherein the guide section 121 is located in the second cold plate area 120 and the bottom of the groove is inclined relative to the bottom surface of the battery pack cold plate 100, and the confluence section 122 is located in the first cold plate area 110 and is connected to the guide section 121.

[0042] Also refer to Figure 6, a plurality of battery cells 300 are arranged in the battery compartment 220, and the plurality of battery cells 300 are stacked along the first direction, and the ends of the battery cells 300 provided with poles are located on both sides of the battery pack cold plate 100 along the first direction. As described above, since the position of the poles of the battery cells 300 generates a large amount of heat, condensed water is easily generated, and by making the guide section 121 located in the second cold plate area 120 and the bottom of the groove inclined relative to the bottom surface of the battery pack cold plate 100, the accumulated condensed water can be guided to the confluence section 122 and can be absorbed by the liquid absorption member 13 arranged in the confluence section 122. At the same time, since the confluence section 122 corresponds to the water inlet and outlet of the battery pack cold plate 100, the condensed water generated at the water inlet and outlet position can also be absorbed by the liquid absorption member 13.

[0043] Further, the guide section 121 may include two, and the two guide sections 121 are respectively arranged on both sides of the cold plate body 11 along the first direction, and the two guide sections 121 are connected to the bus section 122. That is, the guide sections 121 are arranged at both ends of the battery cell 300 where the poles are arranged, and a larger number of guide sections 121 is also conducive to improving the efficiency of the guide.

[0044] According to a second aspect of an embodiment of the present disclosure, a battery pack is further provided. The battery pack includes the battery pack cold plate 100 in any one of the above embodiments and has all the beneficial effects thereof, which will not be described in detail herein.

[0045] The battery pack may also include a tray 200 disposed on the upper surface of the battery pack cold plate 100, and a power distribution compartment 210 suitable for installing power distribution and a battery compartment 220 suitable for installing the battery cell 300 are formed in the tray 200. For example, the tray 200 may be constructed as a rectangular frame, and a first partition 201 is provided inside the frame extending along the second direction to divide the rectangular frame into a power distribution compartment 210 and a battery compartment 220. In addition, a plurality of second partitions 202 extending along the second direction may be provided in the battery compartment 220, and the plurality of second partitions 202 are spaced along the first direction to divide the battery compartment 220 into a plurality of sub-compartments to accommodate a plurality of battery modules respectively. Correspondingly, the battery pack cold plate 100 is provided with a guide groove 12, the bottom of the guide groove 12 is configured to be inclined relative to the bottom surface of the battery pack cold plate 100, and the lower end of the guide groove 12 extends to a position corresponding to the power distribution compartment 210, and the liquid absorbent 13 is provided at the lower end of the guide groove 12.

[0046] It should be noted that the tray 200 is formed with a power distribution compartment 210 suitable for installing power distribution and a battery compartment 220 suitable for installing battery cells 300, which is not limited to the aforementioned formation by the first partition 201, and the first partition 201 may not be provided and only divided in space. In addition, the arrangement of the power distribution compartment 210 and the battery compartment 220 is not limited to the horizontal arrangement in the first direction, and can also be arranged up and down according to the installation space. In this case, the structure of the battery pack cold plate 100 does not need to be changed, but the first cold plate area 110 of the battery pack cold plate 100 is still spatially corresponding to the power distribution compartment 210, and the second cold plate area 120 is spatially corresponding to the battery compartment 220.

[0047] A plurality of battery cells 300 are arranged in the battery compartment 220, and the plurality of battery cells 300 are stacked along a first direction, and the ends of the battery cells 300 provided with poles are located on both sides of the battery pack cold plate 100 along the first direction, wherein the battery pack cold plate 100 includes a cold plate body 11 provided inside for the flow of cooling medium, and a guide groove 12 is arranged around the cold plate body 11, and the guide groove 12 includes a guide section 121 extending along the first direction, wherein the groove wall of the guide section 121 away from the cold plate body 11 exceeds the end of the battery cell 300. wherein the groove wall of the guide section 121 away from the cold plate body 11 exceeds the end of the battery cell 300, so that the condensed water generated in the battery compartment 220 can directly flow into the guide section 121 to avoid overflowing outward.

[0048] Furthermore, the guide groove 12 can also include a junction section 122 whose position corresponds to the distribution warehouse 210 and extends along the second direction, and the extension direction of the second direction is perpendicular to the first direction, wherein the junction section 122 is connected to the guide section 121, and multiple liquid absorbent parts 13 are arranged at intervals along the extension direction of the junction section 122.

[0049] In addition, if Figure 7 As shown, the battery pack may also include a protective plate 400 detachably disposed at the bottom of the battery pack cold plate 100 and an upper cover 500 covering the top of the tray 200. Optionally, a sealing ring 600 disposed between the protective plate 400 and the battery pack cold plate 100 may also be included. When replacing and repairing the liquid absorbent part 13, it is only necessary to remove the protective plate 400 disposed at the bottom of the battery pack cold plate 100 to expose the mounting part 14, and then remove the mounting part 14 together with the integrally constructed liquid absorbent part 13 from the bottom of the battery pack, thereby eliminating the need to dismantle the battery pack to expose the internal structure of the battery compartment 220, and making disassembly and assembly convenient, which is conducive to improving work efficiency.
