[0064] At present, from the perspective of market development, the application of batteries is becoming more and more extensive. Batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of battery application areas, its market demand is also constantly expanding.

[0065] The battery involved in the embodiment of the present application can be used in, but not limited to, electrical equipment such as vehicles, ships or aircraft. The battery comprising the battery cells, batteries, etc. involved in the present application can be used to form the electrical equipment.

[0066] The battery mentioned in the embodiments of the present application refers to a single physical module including one or more battery cells to provide higher voltage and capacity. For example, the battery may include a battery module or a battery pack. The battery generally includes a box for encapsulating one or more battery cells. The box can prevent liquid or other foreign matter from affecting the charging or discharging of the battery cells.

[0067] Battery cells can be cylindrical, flat, rectangular or other shapes. Battery cells are generally divided into three types according to the packaging method: cylindrical battery cells, square battery cells and soft-pack battery cells.

[0068] Multiple battery cells can be connected in series and / or in parallel via electrode terminals for use in various applications. In some high-power applications such as electric vehicles, the application of batteries includes three levels: battery cells, battery modules and battery packs. With the development of technology, the battery module level can be omitted, that is, the battery pack is directly formed from battery cells. This improvement improves the weight energy density and volume energy density of the battery system while significantly reducing the number of components. The battery pack here is equivalent to the battery mentioned in this application.

[0070] It should be understood that the technical solutions described in the embodiments of the present application are not limited to the batteries and electrical equipment described above, but can also be applied to all batteries including a box and electrical equipment using the battery.

[0071] Typically, a battery module includes a battery cell and a Cell Contacting System (CCS) assembly, and the Cell Contacting System (CCS) assembly can realize series and parallel connection between multiple battery cells.

[0072] The wiring harness isolation plate assembly includes two stacked insulating film layers with an intermediate layer disposed between the two insulating film layers. The wiring harness isolation plate assembly is manufactured through a hot pressing process, wherein the intermediate layer is used to realize functions such as collecting the temperature and voltage of the battery cell.

[0073] During the production process of the wire harness isolation plate assembly, there are many foreign objects in the production workshop of the wire harness isolation plate assembly. In the process of connecting the insulating film layer and the middle layer, it is easy for foreign objects to enter between the insulating film layer and the middle layer. Among them, when the foreign objects are metal structures, it is easy to pierce the surface of the middle layer, causing the wire harness isolation plate assembly to fail and posing a safety hazard to the battery.

[0074] In order to solve this problem, an embodiment of the present application proposes a wiring harness isolation plate assembly, which includes an intermediate layer, a first insulating film layer and a second insulating film layer, wherein the first insulating film layer is arranged on one side of the intermediate layer in a stacked manner, and the second insulating film layer is arranged on the other side of the intermediate layer in a stacked manner, at least one of the first insulating film layer and the second insulating film layer is a translucent structure and a transparent structure, and the first insulating film layer and the second insulating film layer are respectively connected to the intermediate layer.

[0075] The embodiments of the present application respectively set the first insulating film layer and the second insulating film layer on both sides of the middle layer, and set at least one of the first insulating film layer and the second insulating film layer to be a translucent structure and a transparent structure. This makes it convenient for the operator to observe foreign matter between the first insulating film layer and the middle layer and / or foreign matter between the second insulating film layer and the middle layer, identify the type of foreign matter, and reduce the probability of failure of the wiring harness isolation plate assembly due to foreign matter mixed into the metal structure, thereby reducing the safety hazard of the battery.

[0076] The battery in the embodiments of the present application can be used on electrical equipment such as vehicles, and can also be installed on electrical equipment that requires the battery to be installed in advance.

[0077] The wiring harness isolation plate assembly in the embodiment of the present application can be used in batteries, and can also be used in other products that require insulation protection.

[0078] The structure in the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0079] The first aspect of the embodiment of the present application provides a wiring harness isolation plate assembly 10, such as Figures 1 to 3 As shown, the wire harness isolation plate assembly 10 includes an intermediate layer 13, a first insulating film layer 11 and a second insulating film layer 12. The first insulating film layer 11 is arranged on one side of the intermediate layer 13 in a stacked manner and is connected to the intermediate layer 13; the second insulating film layer 12 is arranged on the other side of the intermediate layer 13 in a stacked manner and is connected to the intermediate layer 13; at least one of the first insulating film layer 11 and the second insulating film layer 12 is a translucent structure or a transparent structure.

[0080] It should be noted that the intermediate layer 13 mentioned here may be a single-layer structure or a double-layer structure, wherein a first insulating film layer 11 and a second insulating film layer 12 connected to the intermediate layer 13 are respectively disposed on opposite sides of the intermediate layer 13 .

[0081] In addition, the transparent structure here refers to a structure made of transparent materials, which allows all light to pass through smoothly, such as transparent glass or transparent plastic. The translucent structure refers to a structure made of translucent materials, which allows part of the light to pass through smoothly, such as translucent glass or translucent plastic. These are common materials and will not be described in detail here.

[0082] Here, both the first insulating film layer 11 and the second insulating film layer 12 can be hot-pressed insulating films, which can have the function of insulating protection. The first insulating film layer 11 and the second insulating film layer 12 can be connected to the middle layer 13 respectively by hot-pressing process. Of course, the first insulating film layer 11 and the second insulating film layer 12 can also be connected to the middle layer 13 by other methods, such as bonding.

[0083] The embodiment of the present application arranges the first insulating film layer 11 and the second insulating film layer 12 on both sides of the middle layer 13 respectively, and sets at least one of the first insulating film layer 11 and the second insulating film layer 12 to be a translucent structure and a transparent structure. This makes it convenient for the operator to observe foreign matter between the first insulating film layer 11 and the middle layer 13 and / or foreign matter between the second insulating film layer 12 and the middle layer 13, identify the type of foreign matter, reduce the probability of failure of the wiring harness isolation plate assembly 10 due to foreign matter mixed into the metal structure, and thus reduce the safety hazard of the battery 100.

[0084] Alternatively, if Figure 3 As shown, the first insulating film layer 11 includes a first film layer 111 and a first adhesive layer 112 connected to each other, the first adhesive layer 112 is connected to the intermediate layer 13, and the first film layer 111 and the first adhesive layer 112 are both a semi-transparent structure and a transparent structure.

[0085] It should be noted that the first film layer 111 and the first adhesive layer 112 are both translucent structures and transparent structures, which include multiple situations, such as the first film layer 111 and the first adhesive layer 112 are both translucent structures, or the first film layer 111 and the first adhesive layer 112 are both transparent structures, or the first film layer 111 is a translucent structure and the first adhesive layer 112 is a transparent structure, or the first film layer 111 is a transparent structure and the first adhesive layer 112 is a translucent structure, all of which enable the observer to observe the surface of the intermediate layer 13 through the first insulating film layer 11, thereby identifying the type of foreign matter.

[0086] In the embodiment of the present application, the first insulating film layer 11 includes a first film layer 111 and a first adhesive layer 112 that are connected to each other, wherein the first adhesive layer 112 is connected to the intermediate layer 13 and the first film layer 111 and the first adhesive layer 112 are both of a translucent structure and a transparent structure. The first insulating film layer 11 can be connected to one side of the intermediate layer 13 and the first insulating film layer 11 can be of a translucent structure and a transparent structure, so that the operator can observe the surface of the intermediate layer 13 facing the first insulating film layer 11 through the first film layer 111 and the first adhesive layer 112, and identify foreign matter between the first insulating film layer 11 and the intermediate layer 13.

[0087] In addition, it should be emphasized that, considering the relatively harsh production environment of the wiring harness isolation plate assembly 10, foreign matter may easily enter the surface of the intermediate layer 13. However, if the type of foreign matter does not cause damage to the surface of the intermediate layer 13, the wiring harness isolation plate assembly 10 can be used on the battery 100 without causing any hidden dangers to the use of the battery 100.

[0088] Alternatively, if Figure 3As shown, the second insulating film layer 12 includes a second film layer 121 and a second adhesive layer 122 connected to each other, the second adhesive layer 122 is connected to the middle layer 13, and the second film layer 121 and the second adhesive layer 122 are both a semi-transparent structure and a transparent structure.

[0089] It should be noted that the second film layer 121 and the second adhesive layer 122 are both translucent structures and transparent structures, which include multiple situations, such as the second film layer 121 and the second adhesive layer 122 are both translucent structures, or the second film layer 121 and the second adhesive layer 122 are both transparent structures, or the second film layer 121 is a translucent structure and the second adhesive layer 122 is a transparent structure, or the second film layer 121 is a transparent structure and the second adhesive layer 122 is a translucent structure, all of which enable the observer to observe the surface of the intermediate layer 13 through the second insulating film layer 12, thereby identifying the type of foreign matter.

[0090] In the embodiment of the present application, the second insulating film layer 12 includes a second film layer 121 and a second adhesive layer 122 that are connected to each other, wherein the second adhesive layer 122 is connected to the intermediate layer 13 and the second film layer 121 and the second adhesive layer 122 are both of a translucent structure and a transparent structure. The second insulating film layer 12 can be connected to the other side of the intermediate layer 13, and the second insulating film layer 12 can be of a translucent structure and a transparent structure, so that the operator can observe the surface of the intermediate layer 13 facing the second insulating film layer 12 through the second film layer 121 and the second adhesive layer 122, and identify foreign matter between the second insulating film layer 12 and the intermediate layer 13.

[0091] In addition, the first insulating film layer 11 and the second insulating film layer 12 in the present application are both set to a transparent structure or a semi-transparent structure, which can also facilitate the operator to observe the circuit status in the wiring harness isolation plate assembly 10, identify whether the circuit is slightly disconnected or slightly connected, and block it in time, thereby reducing the probability of problematic products being used in the battery 100, thereby improving the safety of the battery 100.

[0092] Optionally, continue to refer to Figure 3 As shown, Figure 3 The XX direction is the thickness direction of the wire harness isolation plate assembly 10, wherein the thickness t1 of the first film layer 111 is 75 microns to 150 microns, such as 80 microns, 90 microns or 145 microns, etc.; the thickness t2 of the first adhesive layer 112 is 25 microns to 40 microns, such as 28 microns, 32 microns or 35 microns, etc.; the thickness T1 of the second film layer 121 is 75 microns to 150 microns, such as 80 microns, 90 microns or 145 microns, etc.; the thickness T2 of the second adhesive layer 122 is 25 microns to 40 microns, such as 28 microns, 32 microns or 35 microns, etc.

[0093] The embodiments of the present application can ensure that the first film layer 111 and the second film layer 121 have good insulation and mechanical properties, and can ensure that the first adhesive layer 112 and the second adhesive layer 122 can achieve stable bonding with the intermediate layer 13 and reduce the probability of glue overflow by setting the thickness t1 of the first film layer 111 to 75 to 150 microns and / or the thickness t2 of the first adhesive layer 112 to 25 to 40 microns and / or the thickness T1 of the second film layer 121 to 75 to 150 microns and / or the thickness T2 of the second adhesive layer 122 to 25 to 40 microns.

[0094] More specifically, the thickness t1 of the first film layer 111 is 100 microns to 120 microns, such as 105 microns or 110 microns; the thickness t2 of the first adhesive layer 112 is 30 microns to 35 microns, such as 32 microns or 34 microns; the thickness T1 of the second film layer 121 is 100 microns to 120 microns, such as 105 microns or 110 microns; the thickness t2 of the second adhesive layer 122 is 30 microns to 35 microns, such as 32 microns or 34 microns.

[0095] The embodiments of the present application set the thickness t1 of the first film layer 111 to 100 to 120 microns and / or the thickness t2 of the first adhesive layer 112 to 30 to 35 microns and / or the thickness T1 of the second film layer 121 to 100 to 120 microns and / or the thickness T2 of the second adhesive layer 122 to 30 to 35 microns, so that the first film layer 111 and the second film layer 121 can both have good insulation and mechanical properties, and can achieve stable bonding with the intermediate layer 13 and reduce the probability of glue overflow.

[0096] It should be noted that the first adhesive layer 112 and the second adhesive layer 122 can both be made of transparent polyurethane and have an adhesive function. For example, the first adhesive layer 112 and the second adhesive layer 122 are made of polyurethane and a curing agent in a certain ratio and have a transparent color.

[0097] Optionally, at least one of the first film layer 111 and the second film layer 121 is a PET film, a PC film, a PP film or a PE film.

[0098] These materials are common materials, and the characteristics of each material will not be described in detail here. The first film layer 111 and the second film layer 121 can be made of the same material, such as the first film layer 111 and the second film layer 121 are both made of PET film. The first film layer 111 and the second film layer 121 can also be made of different materials, such as the first film layer 111 is made of PET film, and the second film layer 121 is both made of PC film or PP film.

[0099] In the embodiment of the present application, by setting at least one of the first film layer 111 and the second film layer 121 to be a PET film, a PC film, a PP film or a PE film, the insulating properties of these materials can be utilized to enable the wire harness isolation plate assembly 10 to achieve the function of insulation protection.

[0100] In some embodiments of the present application, Figure 3 As shown, the first film layer 111 and the second film layer 121 have the same thickness, and the first adhesive layer 112 and the second adhesive layer 122 have the same thickness.

[0101] This structure allows the first insulating film layer 11 and the second insulating film layer 12 to be symmetrically arranged on opposite sides of the middle layer 13 , making it convenient to install the first insulating film layer 11 and the second insulating film layer 12 on opposite sides of the middle layer 13 .

[0102] In the embodiments of the present application, by making the first film layer 111 and the second film layer 121 of the same thickness and / or the first adhesive layer 112 and the second adhesive layer 122 of the same thickness, the first film layer 111 and the second film layer 121 can be symmetrically arranged on opposite sides of the middle layer 13 and / or the first adhesive layer 112 and the second adhesive layer 122 can be symmetrically arranged on opposite sides of the middle layer 13, so as to facilitate the assembly of the wiring harness isolation plate assembly 10. In some embodiments of the present application, such as Figure 1 and Figure 2 As shown, the middle layer 13 includes a flexible circuit board 131 and a first electrical connection member 132 arranged side by side, and the first electrical connection member 132 is electrically connected to the flexible circuit board 131 .

[0103] It should be noted that the flexible circuit board 131 here is a highly reliable and excellent flexible printed circuit board made of polyimide or polyester film as a substrate, referred to as a soft board or FPC, which has the characteristics of high wiring density, light weight and thin thickness. The first electrical connector 132 mentioned here can be made of aluminum sheet or copper sheet, etc., which can realize series connection, parallel connection or mixed connection between different battery cells 20.

[0106] It should be pointed out that the voltage acquisition module and the temperature sampling module connected to the flexible circuit board 131 are common components. The voltage acquisition module and the temperature sampling module are both sandwiched between the first insulating film layer 11 and the second insulating film layer 12, and the voltage acquisition module and the temperature sampling module are independent of each other. Therefore, through the setting of the first insulating film layer 11 and the second insulating film layer 12, the voltage acquisition module and the temperature sampling module are respectively insulated, and the two are independent of each other and do not affect each other. The structure of the voltage acquisition module and the temperature acquisition module, and the way in which the voltage acquisition module and the temperature acquisition module are connected to the flexible circuit board 131 are not expanded here.

In order to simplify the structure of the figure, Figure 1 In the figure, only four first electrical connectors 132 are shown. In actual use, the number of the first electrical connectors 132 can be determined according to the number of battery cells 20.

[0109] The two ends of the second electrical connector 133 can be respectively welded to the flexible circuit board 131 and the first electrical connector 132, so as to realize the electrical connection between the flexible circuit board 131 and the first electrical connector 132. The second electrical connector 133 can be a nickel sheet or other metal parts with conductive properties.

[0110] In the embodiment of the present application, the second electrical connector 133 is provided, and the flexible circuit board 131 and the first electrical connector 132 are electrically connected via the second electrical connector 133 , so that the electrical connection between the flexible circuit board 131 and the first electrical connector 132 can be conveniently achieved.

[0112] It should be emphasized that the intermediate layer 13, the first insulating film layer 11 and the second insulating film layer 12 of the wiring harness isolation plate assembly 10 of the embodiment of the present application can be made into an integrated structure by a hot pressing process, and the wiring harness isolation plate assembly 10 can be installed on the battery 100.

[0114] The first direction here is consistent with the XX direction, that is, the thickness direction of the wire harness spacer plate assembly 10 .

[0115] The battery cell 20 in the present application may be one or more, and the multiple battery cells 20 may be connected in series, in parallel, or in mixed connection.

[0116] Optionally, the battery 100 further includes two end plates (not shown), which are respectively arranged at both ends of the battery cell 20, that is, the left end and the right end of the battery cell 20. These are common structures of the battery 100 and will not be described in detail here.
