Summary of the Invention

[0004] This disclosure provides a battery pack and a vehicle that can improve the safety of the battery pack.

[0005] According to one aspect of this disclosure, a battery pack is provided, comprising: The enclosure has a receiving cavity; A battery module is disposed in the accommodating cavity and includes a plurality of battery cells spaced apart. The battery module has a column of battery cells extending in a column direction and a row of battery cells extending in a row direction, with a column gap between two adjacent columns of battery cells. A first heat exchange assembly includes a plurality of first heat exchange plates, which are spaced apart along the row direction. The first heat exchange plates are located in the column gaps. Each first heat exchange plate includes a heat exchange element and a plurality of plate bodies connected to the heat exchange element. Each plate body includes a heat insulation part and a heat conduction part, and the heat conduction part is connected to the heat exchange element.

[0006] In one embodiment of this disclosure, the heat-conducting portion is located on both sides of the heat-insulating portion along the row direction; and along a direction perpendicular to the plane formed by the row direction and the column direction, the heat-conducting portion is located on both sides of the heat-insulating portion.

[0007] In one embodiment of this disclosure, the heat-conducting portion has a receiving portion extending along the column direction, and in the same first heat exchange plate, the heat exchange element is fitted into the receiving portion of each of the plates.

[0008] In one embodiment of this disclosure, the heat-conducting portion has a notch that is recessed toward the heat-insulating portion to form the receiving portion, and the heat exchanger mates with the receiving portion.

[0009] In one embodiment of this disclosure, the number of heat exchange elements on the same first heat exchange plate is multiple, with some of the heat exchange elements located at one end of the plate body near the bottom of the housing, and some of the heat exchange elements located at one end of the plate body away from the bottom of the housing.

[0010] In one embodiment of this disclosure, the first heat exchange component further includes an input pipe and an output pipe, the input pipe and the output pipe extending along the row direction and located between the battery module and the housing, the input pipe and the output pipe being connected through the heat exchange component.

[0011] In one embodiment of this disclosure, there is a row gap between two adjacent rows of battery cells; The battery pack further includes a second heat exchange assembly, which includes a plurality of second heat exchange plates and a connecting pipe connected to the second heat exchange plates. The plurality of second heat exchange plates are spaced apart along the column direction and extend along the row direction. The second heat exchange plates are located in the row gaps, and adjacent second heat exchange plates are connected through the connecting pipe.

[0012] In one embodiment of this disclosure, the second heat exchange plate has a snap-fit ​​hole, and the heat exchange element engages with the snap-fit ​​hole.

[0013] In one embodiment of this disclosure, the second heat exchange plate has a notch that communicates with the snap-fit ​​hole, and the heat exchange element engages with the snap-fit ​​hole through the notch.

[0014] In one embodiment of this disclosure, the heat-conducting part and the heat exchanger are connected by a thermally conductive structural adhesive, the thickness of which is 0.2mm to 0.8mm.

[0015] According to another aspect of this disclosure, a vehicle is provided that includes the battery pack described in any of the above embodiments.

[0016] In the battery pack and vehicle disclosed herein, when the battery module is operating, a heat exchange medium can flow into the heat exchanger. Since the heat exchanger is connected to the heat-conducting part, the heat generated by two adjacent battery cells in the same row can be transferred to the plate disposed in the row gap. The heat is then transferred to the heat exchanger through the heat-conducting part of the plate, and finally absorbed by the heat exchange medium in the heat exchanger, thus achieving heat exchange for the battery module. This allows the battery module to operate efficiently, improving its safety and consequently enhancing the safety and reliability of the battery pack. Simultaneously, by providing a heat insulation part, adjacent battery cells in the same row are separated, reducing the possibility of heat transfer from one battery cell to another, minimizing the thermal impact between adjacent battery cells, and further improving the safety of the battery pack. Furthermore, by providing a first heat exchange plate, the structural strength of the battery module can be increased, improving the structural stability and reliability of the battery pack.

[0033] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

[0034] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0035] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” and “third,” etc., are used only as markers and are not a limitation on the number of objects.

[0036] In this article, the row direction X and the column direction Y are perpendicular to each other.

[0037] This disclosure provides a battery pack. See also... Figures 1-8 The battery pack may include a housing 1, a battery module 2, and a first heat exchange assembly 3. The housing 1 has a receiving cavity. The battery module 2 is disposed within the receiving cavity and includes a plurality of battery cells 21 spaced apart and interconnected. The battery module 2 has rows of battery cells extending along the column direction Y and rows of battery cells extending along the row direction X, with column gaps between adjacent rows of battery cells. The first heat exchange assembly 3 includes a heat exchange pipe and a plurality of first heat exchange plates connected to the heat exchange pipe. The heat exchange pipe may contain a heat exchange medium (e.g., liquid or gas). The plurality of first heat exchange plates are spaced apart along the row direction X. The first heat exchange plates are located in the column gaps. Each first heat exchange plate includes a heat exchange element 31 and a plurality of plate bodies 32 connected to the heat exchange element 31. Each plate body 32 includes a heat insulation part 321 and a heat conduction part 322. Along the row direction X, the heat conduction part 322 is located on both sides of the heat insulation part 321. Along a direction perpendicular to the plane formed by the row direction X and the column direction Y, the heat conduction part 322 is located on both sides of the heat insulation part 321, that is, the heat conduction part 322 covers the heat insulation part 322. At least a portion of the heat conduction part 322 is located on the side of the heat insulation part 321 closer to the battery cell 21. The heat conduction part 322 is connected to the heat exchange element 31. The heat exchange element 31 is connected to the heat exchange pipe. The heat exchange element 31 has a tubular structure.

[0038] It should be noted that a battery cell row refers to multiple battery cells 21 in the same row, and a battery cell column refers to multiple battery cells 21 in the same column.

[0039] Thus, in the embodiments of this disclosure, when the battery module 2 is working, the heat exchange medium in the heat exchange pipe can flow into the heat exchange element 31. Since the heat exchange element 31 is connected to the heat conduction part 322, the heat generated by two adjacent battery cells 21 in the same row of battery cells can be transferred to the plate 32 provided in the column gap. The heat is then transferred to the heat exchange element 31 through the heat conduction part 322 of the plate 32. Finally, the heat is absorbed by the heat exchange medium in the heat exchange element 31 to achieve heat exchange for the battery module 2, enabling the battery module 2 to work efficiently and improving the safety of the battery module 2, thereby improving the safety and reliability of the battery pack. Of course, when the battery module 2 is working in a low-temperature environment (e.g., winter), the heat exchange medium can have a higher temperature. When the heat exchange medium flows through the heat exchange element 31, the heat it carries can be transferred to the battery cells 21 through the heat conduction part 322, so that the battery module 2 can work normally in a low-temperature environment. Meanwhile, by providing a heat insulation section 321, adjacent battery cells 21 in the same row are separated, reducing the possibility of heat transfer from one battery cell 21 to another, thus minimizing the heat impact between adjacent battery cells 21 and further improving the safety of the battery pack. Furthermore, by providing a first heat exchange plate, the structural strength of the battery module 2 can be increased, improving the structural stability and reliability of the battery pack.

[0040] The following is a detailed description of each part of the battery pack: The accommodating cavity is the internal space of the housing 1, used to accommodate the battery module 2. See also [reference needed] for some embodiments of this disclosure. Figure 1 The housing 1 may include a base plate 11 and a frame 12 disposed on the base plate 11. The frame 12 may be a polygonal structure formed by multiple side plates; for example, the frame 12 may include four side plates, which may form a rectangular frame 12. The frame 12 may be placed on the base plate 11 and can be connected to the base plate 11 by means of adhesive, welding, or screws or other connectors. The accommodating cavity is located within the space enclosed by the frame 12 and the base plate 11.

[0041] In addition, see Figure 1 The box body 1 may also include a box cover 13, which can cover the side of the frame 12 away from the bottom plate 11, thereby forming an accommodating space together with the frame 12 and the bottom plate 11.

[0042] Furthermore, in order to increase the accommodating space, at least a portion of the base plate 11 and the lid 13 may be raised in a direction away from the frame 12.

[0043] In one embodiment of this disclosure, the individual battery cells 21 of the battery module 2 can be connected in series or in parallel. The battery cells 21 can be blade battery cells 21, prismatic batteries or other types of battery cells 21, which can be set according to requirements and are not limited here.

[0044] In one embodiment of this disclosure, see Figure 1 The battery pack may also include an insulating filler 5, which can be filled between the battery module 2 and the inner wall of the accommodating cavity, or between the battery module 2 and the cover 13, to limit the position of the battery module 2. The insulating filler 5 may be made of foam or other insulating materials.

[0045] In one embodiment of this disclosure, see Figure 1 The battery pack may also include a bottom protective plate 6, which can be fixed to the side of the bottom plate 11 away from the battery module 2 by means of adhesive bonding, welding or bolt connection, so as to protect the housing 1 and the battery module 2.

[0046] In one embodiment of this disclosure, see Figure 6 , Figure 7 , Figure 8 The heat-conducting part 322 has a receiving part 323 extending along the column direction Y. The receiving part 323 is disposed through the heat-conducting part 322. In the same first heat exchange plate, the heat exchange element 31 is fitted into the receiving part 323 of each plate body 32. In this way, the receiving part 323 facilitates the positioning and installation of the heat exchange element 31, reduces the installation difficulty of the heat exchange element 31 and the plate body 32, and improves the installation efficiency of the battery pack.

[0047] In one embodiment of this disclosure, the cross-sectional shape of the receiving portion 323 can be circular, elliptical, triangular, square, or irregular geometric shape, depending on specific requirements, and is not limited herein.

[0048] In one embodiment of this disclosure, see Figure 12 The heat-conducting part 322 has a notch 324, which is recessed toward the heat-insulating part 321 to form a receiving part 323, and the heat exchanger 31 mates with the receiving part 323. In this way, by providing a notch 324 in the heat-conducting part 322, the heat exchanger 31 can pass through the notch 324 and mate with the receiving part 323, which facilitates the installation of the heat exchanger 31 and further improves the installation efficiency of the battery pack.

[0049] In one embodiment of this disclosure, the notch 324 and the receiving portion 323 may form a cavity of "U", "V" shape or other irregular shape, depending on the specific requirements, and are not limited herein.

[0050] In one embodiment of this disclosure, the heat-conducting part 322 and the heat exchanger 31 are connected by a thermally conductive structural adhesive, the thickness of which is 0.2mm to 0.8mm. Further, the thickness of the thermally conductive structural adhesive is 0.3mm to 0.5mm. For example, the thickness of the thermally conductive structural adhesive can be 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, or 0.8mm. This allows the thermally conductive structural adhesive to have a suitable thickness, facilitating the connection between the heat exchanger 31 and the plate 32, improving the connection performance of the heat exchanger 31, and also promoting heat transfer. It can absorb dimensional tolerances during the installation of the battery cell 21 (e.g., the length tolerance of the battery cell 21), thus improving the space utilization of the accommodating cavity. In other embodiments of this disclosure, the heat-conducting part 322 and the heat exchanger 31 are connected by double-sided adhesive.

[0051] In one embodiment of this disclosure, the heat-conducting part 322 and the battery cell 21 can be in contact, or the heat-conducting part 322 and the battery cell 21 can be connected by a thermally conductive structural adhesive to improve the efficiency of heat transfer and facilitate heat exchange of the battery cell 21.

[0052] In one embodiment of this disclosure, the heat-conducting part 322 may be a coating or a heat-conducting plate, and there is no limitation herein.

[0053] In one embodiment of this disclosure, the material of the heat insulation part 321 can be a heat insulation material such as epoxy resin, and the material of the heat conduction part 322 can be a heat conduction metal material such as aluminum or copper.

[0054] In one embodiment of this disclosure, the heat-conducting part 322 may be provided only on the side of the heat-insulating part 321 near the battery cell 21, so that the heat-insulating part 321 and the heat-conducting part 322 form a "sandwich" structure, thereby reducing the probability of heat mutual influence between two adjacent battery cells 21 and improving the safety of the battery module 2.

[0055] In one embodiment of this disclosure, the number of heat exchange elements 31 on the same first heat exchange plate is multiple, with some heat exchange elements 31 located at the end of the plate 32 near the bottom of the housing 1, and some heat exchange elements 31 located at the end of the plate 32 away from the bottom of the housing 1. For example, the number of heat exchange elements 31 on the same first heat exchange plate can be two, with one heat exchange element 31 located at the end of the plate 32 near the bottom of the housing 1, and the other heat exchange element 31 located at the end of the plate 32 away from the bottom of the housing 1. The bottom of the housing 1 can be the bottom plate 11 of the housing 1. As another example, the number of heat exchange elements 31 on the same first heat exchange plate can be three, with two heat exchange elements 31 located at the end of the plate 32 near the bottom of the housing 1, and the remaining heat exchange element 31 located at the end of the plate 32 away from the bottom of the housing 1. Thus, by providing at least one heat exchange element 31 at both the top and bottom of the same plate 32, it is beneficial to improve the heat exchange efficiency of the battery module 2.

[0056] In one embodiment of this disclosure, see Figure 2 , Figure 3 , Figure 4 The heat exchange pipe may include an inlet pipe 33 and an outlet pipe 34. The inlet pipe 33 and outlet pipe 34 extend along the row direction X and are located between the battery module 2 and the housing. The inlet pipe 33 and outlet pipe 34 are connected through a heat exchange component, and are located on opposite sides of the battery module 2 along the row direction X. Thus, the heat exchange medium can be transported to the heat exchange component through the inlet pipe 33, and the heat exchange medium after heat exchange flows out through the outlet pipe 34, facilitating the circulation of the heat exchange medium.

[0057] In one embodiment of this disclosure, see Figures 2-5 The number of input pipe 33, output pipe 34, and heat exchanger 31 can be two. One input pipe 33 and one output pipe 34 are connected through one heat exchanger 31. The input pipe 33 and the output pipe 34 are located on both sides of the battery module 2 along the X direction. One heat exchanger 31 is located at the end of the plate 32 away from the bottom plate 11, and the other heat exchanger 31 is located at the end of the plate 32 close to the bottom plate 11, which helps to improve the heat exchange efficiency of the battery module 2.

[0058] In one embodiment of this disclosure, there is a row gap between adjacent rows of battery cells. See also Figures 2-6The battery pack also includes a second heat exchange assembly 4, which comprises multiple second heat exchange plates 41 and connecting pipes 42 connected to the second heat exchange plates 41. The multiple second heat exchange plates 41 are spaced apart along the column direction Y and extend along the row direction X, with the second heat exchange plates 41 located in the row gaps. Adjacent second heat exchange plates 41 are connected by connecting pipes 42. In this way, the second heat exchange plates 41 can exchange heat for the battery cells 21 in two adjacent rows of battery cells, achieving heat exchange on all four sides of the battery cells 21, thus improving the heat exchange efficiency and safety of the battery module 2. The multiple second heat exchange plates 41 are connected by connecting pipes 42 to provide heat exchange medium to multiple heat exchange plates simultaneously.

[0059] In one embodiment of this disclosure, the second heat exchange plate 41 has a heat exchange channel. One second heat exchange plate 41 is connected to two connecting pipes 42. The heat exchange channel has an inlet and an outlet, located at the same end of the second heat exchange plate 41. The inlet communicates with one connecting pipe 42, and the outlet communicates with the other connecting pipe 42, allowing the heat exchange medium to flow from one connecting pipe 42 into the inlet, undergo heat exchange within the heat exchange channel, and then flow from the outlet into the other connecting pipe 42. The heat exchange channel extends along a curved or zigzag trajectory. For example, the heat exchange channel can extend along an S-shaped curve, a C-shaped curve, a spiral curve, or a pulsating zigzag trajectory to increase the length of the heat exchange channel within the heat exchange plate, thereby ensuring sufficient heat exchange of the heat exchange medium within the heat exchange channel and improving heat exchange efficiency.

[0060] In one embodiment of this disclosure, see Figure 6 , Figure 7 , Figure 9 The second heat exchange plate 41 has a snap-fit ​​hole 411, and the heat exchange element 31 can mate with the snap-fit ​​hole 411. In this way, by mates with the snap-fit ​​hole 411, the second heat exchange plate 41 avoids the heat exchange element 31, which facilitates the installation of the heat exchange element 31.

[0061] In one embodiment of this disclosure, see Figure 10 , Figure 11 , Figure 13 The second heat exchange plate 41 has a notch 412, which communicates with the snap-fit ​​hole 411 along the direction of the plate body 32 away from the bottom plate. The heat exchange component 31 is engaged with the snap-fit ​​hole 411 through the notch 412. In this way, the notch 412 facilitates the positioning and installation of the heat exchange component on the second heat exchange plate 41, further improving the installation efficiency of the battery pack.

[0062] In one embodiment of this disclosure, the notch 412 and the snap-fit ​​hole 411 can form a cavity with a "U" shape, a "V" shape, or other irregular shapes, depending on the specific requirements, and are not limited herein.

[0063] In one embodiment of this disclosure, the second heat exchange plate 41 and the heat exchange component 31 can be connected by a thermally conductive structural adhesive, the thickness of which is 0.2mm to 0.8mm. Further, the thickness of the thermally conductive structural adhesive is 0.3mm to 0.5mm. For example, the thickness of the thermally conductive structural adhesive can be 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, or 0.8mm. This allows the thermally conductive structural adhesive to have a suitable thickness, which on the one hand facilitates the connection between the heat exchange component 31 and the second heat exchange plate 41, improving the connection performance of the heat exchange component 31; on the other hand, it facilitates heat transfer, can absorb dimensional tolerances during the installation of the battery cell 21 (e.g., the thickness tolerance of the battery cell 21 along the Y-direction), and helps improve the space utilization of the accommodating cavity.

[0064] In one embodiment of this disclosure, the battery pack may further include a third heat exchange plate, which may be disposed between the battery module 2 and the base plate 11 for heat exchange of the bottom of the battery module 2, so as to achieve heat exchange of the five surfaces of the battery cell 21 and further improve the heat exchange efficiency of the battery pack.

[0065] This disclosure also provides a vehicle that may include the battery pack of any of the above embodiments. This vehicle possesses all the beneficial effects of the aforementioned battery pack. The vehicle may be a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle. New energy vehicles may be pure electric vehicles, hybrid electric vehicles, or range-extended vehicles, etc. This application does not impose any special limitations on the aforementioned vehicles.

[0066] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the appended claims.
