Description

Technical Field

[0001] This utility model relates to the field of battery cell technology, specifically to a prefabricated integrated structure of aluminum busbar, NTC and terminal block and a battery. Background Technology

[0002] In current battery production, the process involves connecting the battery cell and aluminum busbar according to the cell orientation, then taking an NTC (negative temperature coefficient thermistor), installing the NTC at the desired location, and then taking a terminal block for collecting the cell voltage and installing it at the desired location. This method of placing the aluminum busbar and setting the NTC and terminal block positions one by one results in low production efficiency.

[0003] Therefore, it is necessary to provide a prefabricated integrated structure of aluminum busbar, NTC and terminal block to overcome the shortcomings of the prior art. Summary of the Invention

[0004] The purpose of this invention is to provide a prefabricated integrated structure of aluminum busbar, NTC and terminal block and a battery. The aluminum busbar, NTC and terminal block belong to the same prefabricated integrated structure, which improves the efficiency of battery manufacturing.

[0005] To achieve the above objectives, this utility model provides a prefabricated integrated structure of an aluminum busbar, an NTC, and a terminal block, including an insulating substrate, an aluminum busbar mounted on the insulating substrate, a negative temperature coefficient thermistor mounted on the insulating substrate, and a terminal block mounted on the insulating substrate.

[0006] In a preferred embodiment, the aluminum busbar is mounted on the insulating substrate via a first thin film.

[0007] In a preferred embodiment, the first film is an insulating film.

[0008] In a preferred embodiment, the negative temperature coefficient thermistor is mounted on the insulating substrate via a second thin film.

[0009] In a preferred embodiment, the first film is an insulating film.

[0010] In a preferred embodiment, the insulating substrate is a plastic sheet.

[0011] In a preferred embodiment, the insulating substrate is a polycarbonate plastic sheet.

[0012] This utility model also provides a battery, including a battery cell and a prefabricated integrated structure of an aluminum busbar, a negative temperature coefficient thermistor and a terminal block, wherein the battery cell is connected to the aluminum busbar and the terminal block.

[0013] Compared with the prior art, this utility model provides a prefabricated integrated structure of aluminum busbar, NTC and terminal block and a battery. The aluminum busbar, NTC and terminal block are prefabricated on an insulating substrate. With this design, it is not necessary to obtain the aluminum busbar, NTC and terminal block one by one and determine the position of the aluminum busbar, NTC and terminal block one by one in the battery manufacturing process. In actual production, it improves the assembly efficiency of battery manufacturing and saves production costs.

[0014] To make the above-mentioned objectives, features and advantages of the utility model more apparent and understandable, preferred embodiments of the present utility model are described below in detail with reference to the accompanying drawings. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0019] In an embodiment of this utility model, a prefabricated integrated structure 100 of aluminum busbar 102, NTC 103 and terminal block 104 is provided, see [link to relevant documentation]. Figure 1 It includes an insulating substrate 101, an aluminum busbar 102 mounted on the insulating substrate 101, an NTC 103 mounted on the insulating substrate 101, and a terminal block 104 mounted on the insulating substrate 101.

[0020] In this embodiment, the prefabricated integrated structure 100 also includes a first film. The aluminum busbar 102 is mounted on the insulating substrate 101 through the first film, that is, the aluminum busbar 102 is pressed onto the insulating substrate 101. The first film is used as the film for pressing. The first film is an insulating film, such as PVC film.

[0021] In this embodiment, the prefabricated integrated structure 100 also includes a second film. The NTC103 is mounted on the insulating substrate 101 through the second film, that is, the NTC103 is pressed onto the insulating substrate 101. The second film is used as the film for pressing. The second film is an insulating film, such as PVC film.

[0022] Understandably, the aluminum busbar 102 and NTC 103 can also be mounted on the insulating substrate 101 in other ways, as examples rather than limitations. For example, the aluminum busbar 102 can be mounted on the insulating substrate 101 by screws, the NTC 103 can be mounted on the insulating substrate 101 by fasteners, or it can be glued to the insulating substrate 101. Since the aluminum busbar 102 not only has the function of fixing the battery installation and preventing the battery from short-circuiting, but also has the function of heat dissipation, when glue is used for bonding, a glue with good thermal conductivity should be used for bonding.

[0023] In this embodiment, the terminal block 104 can be bonded to the insulating substrate 101 with solid glue or liquid glue, or it can be installed in other ways, such as by mounting (pressing) it onto the insulating substrate 101 with a third insulating film.

[0024] Here, the insulating substrate 101 is a plastic board, specifically, the insulating substrate 101 is a PCP (polycarbonate plastic) board.

[0025] In this embodiment, aluminum busbar 102, NTC 103 and terminal block 104 are located on the same side of insulating substrate 101 and are all pressed onto insulating substrate 101 by insulating film.

[0026] It is understandable that the number of aluminum busbars 102, NTC103 and terminal blocks 104 is not limited. The number of aluminum busbars 102, NTC103 and terminal blocks 104, as well as their positions, are set according to actual production needs. Figure 1 As an example, the insulating substrate 101 has nine aluminum busbars 102, two NFCs, and one terminal block 104. This prefabricated integrated structure corresponds to a battery with eight cells. The two NFCs are spaced a certain distance apart, and the terminal block 104 detects the voltage of all cells. It is not limited whether the terminal block 104 detects the voltage of each cell, a portion of the cells, the total voltage, or something else entirely.

[0027] In this embodiment, the prefabricated integrated structure 100 is applied to obtain the prefabricated integrated structure 100, and the battery cell is connected to the prefabricated integrated structure 100. The aluminum busbar 102 serves as a connector for the battery cell, which can connect the battery cells into a series or parallel battery pack. The NTC 103 is used to sense the real-time temperature of the battery cell, and the terminal block 104 is used to collect the voltage of the battery cell.

[0028] In summary, based on the prefabricated integrated structure 100 of this invention, it is unnecessary to obtain the aluminum busbar 102, NTC 103, and terminal block 104 one by one, or to determine the position of each of the aluminum busbar 102, NTC 103, and terminal block 104 individually. Compared to the connection process between the battery cell and the aluminum busbar 102, NTC 103, and terminal block 104 during battery fabrication in the prior art, this invention improves the assembly efficiency of battery fabrication in actual production and saves production time and costs. Compared to this stage of battery fabrication in the prior art, the prefabricated integrated structure 100 of this invention can replace the manual assembly of the aluminum busbar 102, NTC 103, and terminal block 104 in the prior art, increasing assembly efficiency by approximately three times. This invention can also reduce the battery manufacturing defect rate and greatly save production costs.

[0029] This utility model also provides a battery, which includes a battery cell and a prefabricated integrated structure 100 of an aluminum busbar 102, an NTC 103 and a terminal block 104, wherein the battery cell is connected to the aluminum busbar 102 and the terminal block 104.

[0030] The NTC103 is used to sense and detect the real-time temperature of the battery cell. The NTC103 is connected to the BMS. When the battery cell temperature reaches the set value, the BMS disconnects the battery cell load circuit to achieve a protection function.

[0031] The voltage of each battery cell is led to terminal block 104 through the connecting line, and then connected to BMS through the acquisition line connected to terminal block 104 to achieve battery cell voltage monitoring.

[0032] Typically, the battery cell is also connected to the NTC103 to supply power to the NTC103.

[0033] It is understandable that by adopting the aforementioned prefabricated integrated structure 100, the battery production efficiency can be effectively improved, thereby reducing the battery production cost to a certain extent.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
