Description
Technical Field
[0001] This utility model belongs to the field of all-solid-state battery technology, specifically, it relates to an all-solid-state cell module heating component, an all-solid-state cell module, and an all-solid-state battery pack. Background Technology
[0002] With the development of lithium-ion batteries in energy storage, new energy vehicles, rail transit, communications, 3C and other application fields, people have put forward higher requirements for the safety of lithium-ion batteries. All-solid-state lithium-ion batteries are regarded as an important direction of next-generation battery technology due to their intrinsic safety.
[0003] However, all-solid-state batteries use all-solid-state electrolytes, and their high ionic conductivity depends on high-temperature environments. Prolonged operation at low temperatures can damage all-solid-state lithium-ion batteries. Consequently, compared to traditional lithium-ion batteries that use electrolytes, all-solid-state lithium-ion batteries require heating to maintain their operating temperature. However, due to the different locations of the individual all-solid-state lithium-ion batteries in the battery pack, their heating and cooling rates differ during actual use. This leads to different performance levels for all-solid-state lithium-ion batteries at different temperatures. Furthermore, charging and discharging individual all-solid-state lithium-ion batteries below their operating temperature can affect their lifespan. Therefore, how to reduce the temperature difference between the individual all-solid-state lithium-ion batteries in the battery pack and improve the temperature consistency of each battery is a critical issue that urgently needs to be addressed.
[0004] In view of this, this utility model is proposed. Utility Model Content
[0005] To address one of the problems in the prior art, this invention provides a heating assembly for an all-solid-state battery cell module. It takes into full account that the heat dissipation rate of the battery cells located in the middle of the battery cell module is lower than that of the battery cells located at the edge. By adjusting the arrangement of the heat-conducting components, the heat-conducting components with relatively less heating capacity are used to heat the battery cells in the middle, thereby reducing the temperature difference between the battery cells at the edge and the battery cells in the middle.
[0006] This invention also provides an all-solid-state battery module using the above-mentioned heating components.
[0007] This invention also provides an all-solid-state battery pack having the above-mentioned all-solid-state cell module.
[0008] To solve the above-mentioned technical problems, the first aspect of this utility model provides a heating assembly for an all-solid-state battery cell module, including a heating element and a heat-conducting element. The heat-conducting element includes a heat-conducting plate and a heat-receiving plate. The heat-receiving plate protrudes from the opposite two edges of the heat-conducting plate to the same side of the plane where the heat-conducting plate is located. A plurality of heat-conducting plates are arranged at equal intervals along a preset first direction. Two adjacent heat-conducting elements together form a receiving area for accommodating the battery cell body. The heat-receiving plate is in contact with the heating element. At least one other receiving area exists on each side of the receiving area formed by two heat-conducting elements with heat-receiving plates facing each other. The area of the two heat-receiving plates facing each other is smaller than the area of the heat-receiving plates on other heat-conducting elements.
[0009] Furthermore, the receiving area formed by two heat-conducting elements arranged opposite to each other by the heated plate is located in the middle region of a plurality of receiving areas arranged along a preset first direction.
[0010] Furthermore, the heating plate is configured to be flush with the two side edges of the heating plate where no heating plate is provided.
[0011] Furthermore, several heating plates are flush, and the heating element is a heating plate that is closely attached to the surface of the heating plate.
[0012] Furthermore, the heating element has several heating zones separated along a preset first direction. The temperature of the heating zones near both ends along the preset first direction is higher than that of the other heating zones located in the middle. The receiving area formed by two opposing heat-conducting elements is in close contact with the heating zone located in the middle.
[0013] The second aspect of this utility model provides an all-solid-state battery module, including the all-solid-state battery module heating assembly described above. The battery cell body is respectively disposed in each receiving area formed by two adjacent heat-conducting components, and the spacing between two adjacent heat-conducting plates is adapted to the size of the battery cell body.
[0014] Furthermore, the distance between the two heat-receiving plates on the heat-conducting component is matched with the size of the battery cell body.
[0015] Furthermore, the heat-conducting components are divided into a first heat-conducting component and a second heat-conducting component according to the size of the heat-receiving plate. The heat-receiving plates of the two first heat-conducting components are arranged facing each other. The distance from the end of the heat-receiving plate away from the heat-conducting plate in the first heat-conducting component to the heat-conducting plate is less than or equal to half the distance between two adjacent heat-conducting plates.
[0016] Furthermore, the heat-conducting component also includes a second heat-conducting component, which is respectively disposed on the opposite side of the two first heat-conducting components. The distance from the end of the heated plate away from the heat-conducting plate in the second heat-conducting component to the heat-conducting plate is less than or equal to the distance between two adjacent heat-conducting plates, and the distance from the end of the heated plate away from the heat-conducting plate in the second heat-conducting component to the heat-conducting plate is greater than the distance from the end of the heated plate away from the heat-conducting plate in the first heat-conducting component to the heat-conducting plate.
[0017] The third aspect of this utility model provides an all-solid-state battery pack, which has an all-solid-state cell module and a housing as described in the above-mentioned solution, wherein the all-solid-state cell module is housed in a hollow cavity formed inside the housing.
[0018] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art.
[0019] 1. By adjusting the arrangement of the heating elements, the receiving area formed by the heating plates facing each other avoids the end position of several receiving areas arranged along the preset first direction. Although the heat dissipation speed of the battery cells at the end is relatively faster, it will not correspond to the heat conduction element with a relatively small heating plate area. This makes the high heat dissipation battery cells and low heating heat conduction elements staggered, which can effectively reduce the temperature difference between each battery cell.
[0020] 2. The battery cell located in the middle can have a better heat preservation effect due to the heat radiation of the adjacent battery cells. This application sets the receiving area formed by the heating plates facing each other in the middle area of several receiving areas arranged along a preset first direction. That is, the receiving area with the smallest heating plate area corresponds to the battery cell with the slowest heat dissipation speed and the lowest heating demand. This can better balance the temperature of each battery cell and reduce the temperature difference.
[0021] 3. The heat transfer plates of each heat-conducting component are set flush, which makes the shape of the all-solid-state battery module regular. This allows the heating element to be set as a heating plate that is close to the surface of the heat transfer plate, which helps to reduce the overall size of the all-solid-state battery module, improve energy density and installation convenience.
[0022] 4. The size of the receiving area formed by two adjacent heat-conducting components is adapted to the size of the battery cell body. That is, the heating plate and the heat-receiving plate are attached to different sides of the battery cell body, realizing multi-directional heating of the battery cell body, which effectively improves the heat transfer effect and heat transfer uniformity of the heat-conducting components to the battery cell body.
[0023] 5. The heat-conducting components are divided into a first heat-conducting component and a second heat-conducting component based on the protrusion height of the heat-receiving plates. The heat-receiving plates of the first heat-conducting components are arranged facing each other to form a receiving cavity. The protrusion height of the heat-receiving plates on the two first heat-conducting components is less than or equal to half the thickness of the battery cell body. When the protrusion height of the heat-receiving plates is equal to half the thickness of the battery cell body, the ends of the two heat-receiving plates abut against each other, which provides a more thorough heating effect on the battery cell body. When the protrusion height of the heat-receiving plates is less than half the thickness of the battery cell body, the gap between the ends of the two heat-receiving plates can reserve space for deformation during the compression process of the all-solid-state battery cell module, thereby improving the energy density of the all-solid-state battery cell module and adapting to battery cell bodies of different sizes, thus having higher applicability. The protrusion height of the heat-receiving plates on the second heat-conducting component is greater than the height of the heat-receiving plates on the first heat-conducting component, which can ensure that the temperature of the battery cell bodies at both ends along the stacking direction is consistent. Furthermore, since the heat-receiving plates on the second heat-conducting component have a larger area, it is more conducive to reducing the temperature difference between the edge battery cell body and the middle battery cell body.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.
[0031] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0033] This utility model provides a heating assembly 1 for an all-solid-state battery cell module, such as... Figures 1 to 5 As shown, the device includes a heating element and a heat-conducting element 11. The heat-conducting element 11 includes a heat-conducting plate and heat-receiving plates 113 protruding in the same direction from opposite sides of the heat-conducting plate. A plurality of heat-conducting elements 11 are arranged at intervals along a preset first direction, wherein the heat-conducting plates of two adjacent heat-conducting elements 11 are parallel to each other and spaced evenly. A receiving area for accommodating the battery cell body is formed between any two adjacent heat-conducting elements 11. In order to improve the heating effect, the end of the heat-receiving plate 113 should be as close as possible to the adjacent heat-conducting element 11. Since the heat-receiving plate 113 protrudes from one side, there must be a receiving area formed by two heat-conducting elements 11 interlocking, that is, the heat-receiving plates 113 of the two heat-conducting elements 11 are arranged facing each other, limited by the interval between two adjacent heat-conducting plates. The two opposing heat-receiving plates 113 have a smaller protrusion height than the heat-receiving plates 113 in the other non-opposite heat-conducting components 11. This inevitably results in a smaller heat transfer area between the two interlocking heat-conducting components 11 and the heating component, leading to a lower heating capacity for the cell body within the containment area. This can easily cause a large temperature difference between the cell bodies, which is detrimental to the performance and lifespan of the all-solid-state battery pack. Therefore, this application avoids setting the containment area formed by the interlocking heat-conducting components 11 at the ends of several containment areas arranged along a preset first direction. The containment area with poor heating capacity is used to heat the cell body with relatively better heat preservation effect, which effectively improves the temperature consistency between the cell bodies in the all-solid-state battery module.
[0034] Furthermore, in the all-solid-state battery module using the aforementioned heating component 1, the two battery cells at both ends receive the same heating effect. That is, the entire all-solid-state battery module can be considered to have a temperature zone corresponding to the end battery cell and another temperature zone corresponding to the middle battery cell. This makes it more convenient to adjust the temperature of each temperature zone of the all-solid-state battery module, simplifies the temperature control logic, reduces production costs, and improves temperature regulation efficiency.
[0035] In one embodiment of this solution, the plurality of heat-conducting components 11 are aligned along a preset first direction, that is, the projections of the plurality of heat-conducting components 11 in the first direction completely overlap. At this time, the heat-receiving plates 113 on each heat-conducting component 11 are flush, forming a heat-receiving plane. Correspondingly, the heating element can be set as a heating sheet or heating film 12 that is in close contact with the heating plane. This arrangement makes the shape of the all-solid-state battery module regular, and the heating element does not need to occupy a lot of space, which is beneficial to improving the energy density of the all-solid-state battery pack. In other embodiments, the plurality of heat-conducting components 11 can also be non-aligned in the preset first direction. For example, the heat-receiving plates 113 are flush, but the other two sides of the heat-conducting plates adjacent to the heat-receiving plates 113 are not flush. Those skilled in the art can adjust the arrangement of the heat-conducting plates according to actual use needs.
[0036] To achieve sufficient heating of the all-solid-state battery module, the heat-conducting plate in the heat-conducting component 11 covers the surface of the battery body perpendicular to a preset first direction. As one embodiment of this utility model, the size of the heat-conducting plate in the heat-conducting component 11 is the same as the size of the battery body. At this time, the heating plate 113 is in contact with the side of the battery body, and the two ends of the heat-conducting plate adjacent to the heating plate 113 are flush with the side of the battery body. At this time, the heating plate 113 is not only used to transfer heat to the heat-conducting plate, but also can directly transfer heat to the battery body itself. In order to further improve the heating effect, the heating plate 113 is set to be flush with the two side edges of the heating plate where the heating plate is not provided with the heating plate 113.
[0037] It should be noted that, for ease of description, in the following embodiments, the two heat-conducting elements 11 that are set together to form the receiving area are defined as the first heat-conducting element 111, and the remaining heat-conducting elements 11 are defined as the second heat-conducting element 112. At the same time, to avoid ambiguity, the cell body mentioned in this utility model refers to the part of the cell formed by the stacking or winding of the electrode sheets wrapped by the cell shell, and does not include the tabs or other parts. For pouch cells, the cell body does not include the folded sealing area. Unless otherwise specified, the cell body described in the following embodiments is assumed to be the cell body of a pouch cell.
[0038] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.
[0039] Example 1
[0040] As an embodiment of the present invention, this embodiment provides a heating assembly 1 for an all-solid-state battery module, including ten heat-conducting elements 11, of which two are first heat-conducting elements 111 and eight are second heat-conducting elements 112.
[0041] In this embodiment, as Figure 1 and Figure 2 As shown, ten heat-conducting components 11 are arranged at equal intervals along a preset first direction. The heat-conducting plates in two adjacent heat-conducting components 11 are parallel to each other and have the same spacing. The ten heat-conducting components 11 form nine accommodating areas along the preset first direction, with the gap between any two adjacent heat-conducting components 11 serving as an accommodating area. These accommodating areas are defined as the first to the ninth accommodating areas along the preset first direction. Two first heat-conducting components 111 form the fifth accommodating area, and the remaining eight second heat-conducting components 112 are symmetrically arranged on both sides of the fifth accommodating area to form the remaining eight accommodating areas.
[0042] Furthermore, in this embodiment, the heating plate 113 is set perpendicular to the heat-conducting plate. The heating plate 113 is rectangular in shape, with one end connected to the edge of the heat-conducting plate. The two edges intersecting with the heat-conducting plate are respectively flush with the two sides of the heat-conducting plate without the heating plate 113. The two heat-conducting elements 11 forming any accommodating area do not contact each other. At this time, the projections of the ten heat-conducting elements 11 along the preset first direction are completely overlapping, and the projections in the second direction and the third direction perpendicular to the preset first direction do not overlap. The all-solid-state battery module heating assembly 1 formed by this setting method has the ability to adjust the size of each accommodating area by changing the distance between adjacent heat-conducting elements 11, since the adjacent heat-conducting elements 11 do not contact each other. This allows it to better adapt to the pressing operation in the all-solid-state battery module manufacturing process, which is beneficial to improving the energy density of the all-solid-state battery module. Correspondingly, the heating element in this embodiment is a heating film 12 that covers the heating plane formed by the heating plate 113 and is in close contact with the heating plate 113.
[0043] Furthermore, the protrusion height of the heating plate 113 in the first heat-conducting element 111 is less than the protrusion height of the heating plate 113 in the second heat-conducting element 112. The gap between the heating plates 113 in the two oppositely arranged first heat-conducting elements 111 is the same as the gap between the heating plate 113 in the second heat-conducting element 112 and the adjacent heat-conducting element 11. The difference in gap will not affect the normal pressing of the all-solid-state battery module. Since the heating element transfers heat to the heat-conducting element 11 through the heating plate 113, the size of the heating plate 113 directly affects the heat transfer of the heating film 12 to the heat-conducting element 11. In order to maximize the heat transfer effect of the heating element to the heating plate 113, as a specific implementation of this embodiment, the gap between the heating plates 113 in the two first heat-conducting elements 111 is 17% of the distance between two adjacent heating plates.
[0044] Example 2
[0045] As another embodiment of the present invention, the difference between this embodiment and the first embodiment is that the number of heat-conducting elements 11 is different.
[0046] In this embodiment, as Figure 3 and Figure 4 As shown, the heating assembly 1 includes eleven heat-conducting elements 11, two of which are first heat-conducting elements 111 and nine are second heat-conducting elements 112. The eleven heat-conducting elements 11 are arranged at equal intervals along a preset first direction. The heat-conducting plates in two adjacent heat-conducting elements 11 are parallel to each other and have the same spacing. The eleven heat-conducting elements 11 form ten accommodating areas along the preset first direction, with the gap between any two adjacent heat-conducting elements 11 serving as an accommodating area. These accommodating areas are defined as the first to the tenth accommodating areas along the preset first direction. Two first heat-conducting elements 111 form the fifth accommodating area, and the remaining nine second heat-conducting elements 112 are respectively arranged on both sides of the fifth accommodating area to form the remaining nine accommodating areas.
[0047] In the above scheme, when there is an even number of accommodating areas, the accommodating area formed by the two first heat-conducting elements 111 is selected as one of the two accommodating areas in the middle. While keeping the temperature of the accommodating areas at both ends consistent, the accommodating area with the smaller area of the heating plate 113 is placed in the middle as much as possible. Taking advantage of the better heat preservation effect of the battery cell body in the middle accommodating area, the temperature difference caused by the area of the heating plate 113 is reduced or even smoothed out, thereby achieving the same effect as in the first embodiment.
[0048] Example 3
[0049] As another embodiment of the utility model, this embodiment makes the following improvements based on Embodiment 1.
[0050] In this embodiment, heating films 12 covering and closely adhering to the heating plates 113 on both sides of the heat-conducting component 11 are respectively provided on the outer side of the heating plates 113, and the heating films 12 on both sides are symmetrically arranged; specifically, as shown in the figure Figure 5 As shown, the heating film 12 has three heating zones separated along a preset first direction, namely a first heating zone 121, a second heating zone 122 and a third heating zone 123, wherein the first heating zone 121 and the third heating zone 123 are respectively attached to the heat receiving plates 113 of the heat-conducting components 11 located at both ends; in order to compensate for the heat loss of the battery cell body located at both ends, the density of heating wires in the first heating zone 121 and the third heating zone 123 is greater than the density of heating wires in the second heating zone 122.
[0051] As one embodiment of this invention, the first heating zone 121 and the third heating zone 123 are symmetrically arranged along the centerline of the second heating zone 122. The width of the first heating zone 121 and the third heating zone 123 in the first direction covers the two heating plates 113 located at the ends. This arrangement takes into account the temperature variation gradient of the battery cell body at different positions along the preset first direction. Since the temperature of the battery cell body at the end is lower, the temperature of the battery cell body adjacent to the end will also decrease accordingly. The above arrangement further improves the temperature uniformity of the battery cell body in each accommodating area along the preset first direction. Since the battery cell body in the middle accommodating area has a relatively better heat preservation effect, appropriately reducing the density of the heating wire in the second heating zone 122 can effectively control the temperature of the battery cell body in the middle accommodating area, which is beneficial to reducing the temperature difference between each battery cell body.
[0052] Example 4
[0053] As another embodiment of the present invention, the difference between this embodiment and the first embodiment is that the shape of the heating plate 113 is different.
[0054] In this embodiment, the end of the heating plate 113 away from the heating plate is corrugated. The corrugated ends of the heating plates 113 in the two first heat-conducting components 111 are interlocked, that is, the corrugations of the two heating plates 113 are staggered. This arrangement can achieve mutual positioning of the two first heat-conducting components 111 to a certain extent through the interlocked corrugated ends. The end of the heating plate 113 on the second heat-conducting component 112 can also be corrugated.
[0055] This utility model also provides an all-solid-state battery module using the heating component 1 described in the above embodiments, as detailed below.
[0056] Example 5
[0057] As another embodiment of the present invention, this embodiment provides an all-solid-state battery module, including a plurality of battery cell bodies, and an all-solid-state battery module heating assembly 1 as described in Embodiment 3.
[0058] In this embodiment, the size of the accommodating area formed between two adjacent heat-conducting components 11 is adapted to the size of the battery cell body. That is, in a preset first direction, the heat-conducting components 11 and the battery cell body are arranged alternately in sequence. The heat-conducting plate of the heat-conducting component 11 is in close contact with the surface of the adjacent battery cell body and is adapted to the size. The accommodating area formed by the heat-conducting plate and the heat-receiving plate 113 of the two first heat-conducting components 111 matches the size of the battery cell body. The accommodating area formed by the first heat-conducting component 111 and the second heat-conducting component 112 or the two second heat-conducting components 112 matches the size of the battery cell body. When the battery cell body is accommodated in the accommodating area, it is in close contact with the adjacent heat-conducting plate and the heat-receiving plate 113 on all four sides. In this arrangement, the heat-receiving plate 113 can not only transfer the heat of the heating component to the heating plate, but also directly heat the battery cell body, which improves the utilization rate of the heat provided by the heating film 12 and realizes accurate control of the temperature of the all-solid-state battery cell module.
[0059] Example 6
[0060] As another embodiment of this utility model, the difference between this embodiment and embodiment five is that the size of the heat-conducting element 11 is different.
[0061] In this embodiment, the size of the heating plate is larger than the surface area of the battery cell body it is attached to. When the battery cell body is placed in the receiving area, a gap is formed between it and the heating plates 113 on both sides. The gap is filled with insulation material, that is, the insulation material and the battery cell body together fill the receiving area. In this solution, the heating plate 113 can heat the insulation material while transferring heat to the heating plate, thereby reducing the temperature difference between the battery cell body and the insulation material, reducing the heat loss rate, and thus avoiding large temperature differences caused by the difference in heat dissipation rate of battery cells located in different positions, effectively improving the temperature consistency between each battery cell body.
[0062] This utility model also provides an all-solid-state battery pack having the all-solid-state cell module described in the above embodiments, as detailed below.
[0063] Example 7
[0064] As another embodiment of the present invention, this embodiment provides an all-solid-state battery pack, including a casing and an all-solid-state cell module as described in Embodiment 5.
[0065] In this embodiment, the housing includes a detachable cover and a groove, and the all-solid-state battery module is disposed in the space formed by the cover and the groove. To prevent the all-solid-state battery module from shaking, in this embodiment, the size of the all-solid-state battery module matches the groove of the groove, that is, when installed inside the groove, the all-solid-state battery module abuts against the peripheral wall of the groove. Alternatively, in other embodiments, the size of the all-solid-state battery module is smaller than the size of the groove. To prevent the all-solid-state battery module from shaking, a fixing member for fixing the all-solid-state battery module is also provided in the groove. As a specific implementation, the gap between the fixing member and the all-solid-state battery module and the inner wall of the groove is interference fit.
[0066] To suppress heat dissipation from the all-solid-state battery module, an insulation layer is wrapped around the outside of the all-solid-state battery module. When the size of the all-solid-state battery module matches the groove, the two sides of the insulation layer abut against the groove wall and the all-solid-state battery module, respectively. When the size of the all-solid-state battery module is smaller than the size of the groove, the two ends of the fastener abut against the groove wall and the insulation layer, respectively.
[0067] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
