[0026] The specific embodiments of the present application have been shown in the above figures, and will be described in more detail hereinafter. These figures and the written description are not intended to limit the scope of the present application in any way, but to illustrate the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0027] The exemplary embodiments will be described in detail herein with reference to the attached drawings. In the following description, the same numbers are used to indicate the same or similar components. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present application as detailed in the appended claims.

[0028] As described in the background, the battery heating film of the related art needs to be temporarily protected by using a release paper after production and manufacturing. By pasting the release paper on the pasting surface of the battery heating film, the pasting surfaces of adjacent battery heating films are prevented from affecting each other, so that multiple battery heating films can be stacked when being transported. When the battery heating film is needed, the release paper can be torn off.

[0029] However, when the area of the battery heating film is large, the area of the release paper used is also large. When the release paper with a large area is pasted by using a manual method, the release paper with a large area is not convenient to operate, and air bubbles may occur when being pasted on the battery heating film. When dust enters the air bubbles, dust or other impurities may exist on the pasting surface of the battery heating film, which may affect the connection between the battery heating film and the battery cell.

[0030] In view of the above technical problems, the embodiment of the present application provides a battery heating film release paper, a battery module and an automobile. When the pasting surface of the battery heating film needs to be temporarily protected, a plurality of second connecting papers are pasted on the pasting surface of the battery heating film. Since the area of the second connecting paper is small, the operator can easily paste the plurality of second connecting papers, thereby reducing the probability of air bubbles appearing on the pasting surface of the battery heating film when the second connecting paper is pasted thereon, preventing dust or other impurities from entering the air bubbles between the second connecting paper and the battery heating film, and indirectly improving the connection strength of the battery heating film pasted on the battery cell through the pasting surface. When the release paper needs to be torn off from the pasting surface of the battery heating film, the plurality of second connecting papers at the edge of the battery heating film can be torn off by the release paper, and the second connecting paper between the plurality of second connecting papers can be torn off by the groove and the protrusion, thereby improving the efficiency of tearing off the entire release paper from the battery heating film, and indirectly improving the installation efficiency of the battery heating film installed on the battery cell through the pasting surface.

[0031] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below with specific examples. The following specific examples can be combined with each other, and the same or similar concepts or processes can not be described again in some examples. The embodiments of the present application will be described below with reference to the accompanying drawings.

[0032] In combination with Figure 1 and Figure 2 A battery heating film release paper comprises a first release structure 100 and a plurality of first connecting papers 200 spliced with each other, and the plurality of first connecting papers 200 are arranged along the length direction of a battery heating film 400. The first release structure 100 is arranged on each first connecting paper 200, and the first release structure 100 provides a force point for tearing the first connecting paper 200 from the battery heating film 400.

[0033] In the embodiment, three first connecting papers 200 are arranged along the length direction of the battery heating film 400. The shape of each first connecting paper 200 can be adaptively adjusted according to the shape of the battery heating film 400, for example, the first connecting paper 200 is arranged in a rectangular shape, or the first connecting paper 200 is arranged in an isosceles trapezoidal shape, or the shapes of the three first connecting papers 200 are the same or different. The battery heating film release paper can not only serve as temporary protection for the battery heating film, but also can be pasted on the back of the battery heating film when the battery heating film is working, thereby protecting the back of the battery heating film. In other embodiments, the number of first connecting papers 200 can be adaptively adjusted according to the length of the battery heating film 400, for example, five first connecting papers 200 are arranged. When the battery heating film 400 is arranged in multiple, the three first connecting papers 200 can also be arranged in multiple groups along the length direction of the multiple battery heating films 400.

[0034] By adopting the above technical scheme, by adopting the setting of the plurality of first connecting papers 200, the area of a single first connecting paper 200 is reduced, by pasting the first connecting paper 200 with a smaller area, it is convenient to paste the plurality of first connecting papers 200 on the pasting surface of the battery heating film 400, when the first connecting paper 200 with a smaller area is adopted, the probability of bubbles appearing when the first connecting paper 200 is pasted on the pasting surface of the battery heating film 400 is reduced, thereby preventing dust from entering the bubbles between the first connecting paper 200 and the battery heating film 400, thereby indirectly improving the connection strength of the battery heating film 400 pasted on the battery cell through the pasting surface; by adopting the setting of the first peeling structure 100, when the release paper is not needed, the release paper is conveniently torn off on the battery heating film 400, thereby indirectly improving the installation efficiency of the battery heating film 400.

[0035] In combination with Figure 1 and Figure 2 , the first peeling structure 100 comprises at least one peeling paper 110, the peeling paper 110 is integrally arranged at the edge of the first connecting paper 200, and the peeling paper 110 is located in the same plane as the first connecting paper 200.

[0036] In this embodiment, the peeling paper 110 is integrally produced with the first connecting paper 200, thereby improving the production efficiency of the peeling paper 110 and the first connecting paper 200; the peeling paper 110 is arranged at the middle of the edge of the first connecting paper 200, in other embodiments, the peeling paper 110 can be arranged at the end of the edge of the first connecting paper 200; the peeling paper 110 can also be arranged obliquely, for example, the peeling paper 110 extends away from the edge of the first connecting paper 200 towards the top or bottom of the connecting paper.

[0037] By adopting the above technical scheme, by adopting the setting of the peeling paper 110, the entire first connecting paper 200 can be torn off through the peeling paper 110, thereby improving the convenience of separating the first connecting paper 200 from the battery heating film 400; by integrally arranging the peeling paper 110 with the first connecting paper 200, thereby facilitating the integrated production and manufacturing of the peeling paper 110 and the first connecting paper 200, thereby improving the production efficiency of the plurality of first connecting papers 200.

[0038] In combination with Figure 1 and Figure 2 , one peeling paper 110 is arranged on each first connecting paper 200, and adjacent peeling papers 110 are arranged on opposite sides of the battery heating film 400.

[0039] By adopting the technical scheme, the adjacent release papers 110 are arranged on opposite sides of the battery heating film 400 respectively, so that the adjacent release papers 110 can be torn from the battery heating film 400 in different directions. Since the battery heating film 400 is provided with glue or other adhesives, tearing the first connecting paper 200 in different directions can more effectively break the adhesion of the adhesives and reduce the adhesion between the adjacent first connecting papers 200. In addition, tearing the first connecting paper 200 in different directions can more evenly disperse the tearing force and reduce the local stress on the first connecting paper 200, thereby reducing the risk of tearing or damaging the first connecting paper 200.

[0040] In other embodiments, different numbers of release papers 110 can be arranged on each first connecting paper 200, for example, one release paper 110 is arranged on each side of the same first connecting paper 200, or two release papers 110 are arranged on each side of the same first connecting paper 200. By tearing the first connecting paper 200 at different positions of the first connecting paper 200, the first connecting paper 200 can be prevented from breaking when it is torn, thereby improving the release effect of the first connecting paper 200.

[0041] In combination with Figure 1 and Figure 2 , the release paper 110 is arranged in a rectangular shape, and one side of the rectangular release paper 110 is connected to the first connecting paper 200.

[0042] By adopting the technical scheme, the release paper 110 is arranged in a rectangular shape, thereby facilitating the production and manufacture of the rectangular release paper 110. One side of the rectangular release paper 110 is connected to the first connecting paper 200, thereby increasing the connection width of the release paper 110 and the first connecting paper 200, preventing the connection position of the release paper 110 and the first connecting paper 200 from being broken when the release paper 110 is torn, and improving the connection strength between the release paper 110 and the first connecting paper 200.

[0043] In other embodiments, the shape of the release paper 110 can be adjusted as needed; for example, the release paper 110 is arranged in a semicircular shape, the diameter side of the semicircular release paper 110 is connected to the first connecting paper 200, or the release paper 110 is arranged in a conical shape or other shapes.

[0044] In combination with Figure 1 and Figure 2 , the first connecting paper 200 includes a plurality of second connecting papers 210 that are spliced together, and the plurality of second connecting papers 210 are arranged along the width direction of the battery heating film 400.

[0045] In the embodiment, each first connecting paper 200 includes two second connecting papers 210 spliced with each other; the release paper 110 is arranged on one side of the two second connecting papers 210 away from each other; in other embodiments, the number of the second connecting papers 210 can be adjusted adaptively according to needs; for example, each first connecting paper 200 includes four second connecting papers 210 spliced with each other, and the shape of the second connecting paper 210 can also be adjusted adaptively according to needs.

[0046] By adopting the above technical solution, by including multiple second connecting papers 210 in the first connecting paper 200, the area of a single second connecting paper 210 is reduced, and by pasting the second connecting paper 210 with a smaller area than the first connecting paper 200, it is convenient to paste multiple second connecting papers 210 on the pasting surface of the battery heating film 400, and when a second connecting paper 210 with a smaller area is used, the probability of air bubbles appearing when the second connecting paper 210 is pasted on the pasting surface of the battery heating film 400 is reduced, thereby further preventing dust from entering the air bubbles between the second connecting paper 210 and the battery heating film 400, thereby further indirectly improving the connection strength of the battery heating film 400 pasted on the battery cell through the pasting surface.

[0047] The battery heating film release paper further includes a second release structure 300, the second release structure 300 is arranged between adjacent second connecting papers 210, and the second release structure 300 is used to provide a force point for tearing the second connecting paper 210 from the battery heating film 400.

[0048] By adopting the above technical solution, by adopting the arrangement of the second release structure 300, when the edge second connecting paper 210 is torn off by the release paper 110, it is convenient to tear off the multiple second connecting papers 210 in the middle of the multiple second connecting papers 210 by the second release structure 300, thereby improving the tearing efficiency of the multiple second connecting papers 210 on the battery heating film 400, and indirectly improving the installation efficiency of the battery heating film 400 installed on the battery cell.

[0049] The second release structure 300 includes a groove 310 and a protrusion 320, the protrusion 320 is used to cooperate or disengage with the groove 310, and the protrusion 320 and the groove 310 are arranged on opposite edges of adjacent second connecting papers 210, respectively, and the protrusion 320 is integrally arranged on the edge of the second connecting paper 210.

[0050] In the embodiment, each second peeling structure 300 includes a groove 310 and a protrusion 320, the groove 310 and the protrusion 320 are arranged at the middle of the opposite edges of the two second connecting papers 210 respectively, and the groove is arranged on the same second connecting paper 210; in other embodiments, each second peeling structure 300 can include two grooves 310 and two protrusions 320, and the two grooves 310 are arranged on the two sides of the edge of the second connecting paper 210 respectively, by arranging different numbers of grooves 310 and protrusions 320, the second connecting paper 210 can be torn off along different positions.

[0051] By adopting the above technical scheme, when one of the adjacent second connecting papers 210 is torn off, the second connecting paper 210 can drive the groove 310 or the protrusion 320 to disengage from the protrusion 320 or the groove 310 on the other second connecting paper 210, so that the groove 310 or the protrusion 320 on the other second connecting paper 210 is exposed, thereby facilitating the tearing of the second connecting paper 210 through the exposed groove 310 or protrusion 320. The structure of the protrusion 320 and the groove 310 is simple, which facilitates the batch production of the plurality of second connecting papers 210, and further improves the efficiency of tearing the plurality of second connecting papers 210 on the battery heating film 400. By integrally arranging the protrusion 320 on the edge of the second connecting paper 210, the batch production of the plurality of second connecting papers 210 is further facilitated.

[0052] In combination with Figure 1 and Figure 2 , the groove 310 is arranged in a semicircular shape, and the protrusion 320 is arranged in cooperation with the semicircular groove 310.
