[0015] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0016] A blister CCS component, such as Figure 1 - Figure 4 As shown, it includes a PC plastic sheet 1, two rows of aluminum sheets 2 and a flexible circuit board 3. The PC plastic sheet serves as a supporting base for the aluminum sheet and the flexible circuit board. Then, an aluminum sheet mounting groove 4, an aluminum sheet positioning column 5 and a flexible circuit board positioning column 6 are formed on the PC plastic sheet by vacuum forming. The aluminum sheet is provided with an aluminum sheet mounting hole 7. The aluminum sheet is inserted into the aluminum sheet positioning column through the aluminum sheet mounting hole and installed in the aluminum sheet mounting groove. The flexible circuit board is provided with a flexible circuit board mounting hole 8. The flexible circuit board is inserted into the flexible circuit board positioning column through the flexible circuit board mounting hole. Nickel sheets 9 are provided on both sides of the flexible circuit board and are respectively welded to the two rows of aluminum sheets. Then, the aluminum sheet positioning column and the flexible circuit board positioning column are hot-riveted to fix the aluminum sheet and the flexible circuit board on the PC plastic sheet.
[0017] By locating the aluminum bar positioning column in the aluminum bar installation groove, it is more convenient to install and fix the aluminum bar. In addition, the aluminum bar installation groove is formed with a convex ridge 11 corresponding to the bending groove of the aluminum bar through vacuum forming, and the convex ridge 11 cooperates with the bending groove of the aluminum bar, so that the aluminum bar can be better fixed in the installation groove, further increasing the firmness of the aluminum bar installation. In addition, a battery core welding hole 10 is formed in the aluminum bar installation groove through vacuum forming, and the battery core welding hole 10 is convenient for electrically connecting the aluminum bar to the battery core.
[0018] One end of the nickel sheet is welded to the flexible circuit board, and the other end is tightly attached to the aluminum sheet. The nickel sheet can be welded to the aluminum sheet by welding, or conductive glue can be sandwiched between the aluminum sheet and the nickel sheet and bonded by conductive glue to achieve electrical connection.
[0019] The substrate of the flexible circuit board is a rectangular structure, which is made by a series of processes such as etching and lamination of the substrate. There are related components on the flexible circuit board. The related components include thermistors, which are thermistors with negative temperature coefficients. The temperature changes on the battery pack can be detected in real time through thermistors, and then converted into resistance signals, which are transmitted to the BMS system through the lines and connectors on the flexible circuit board, so that the real-time temperature of each battery module can be obtained. A window 12 corresponding to the thermistor on the flexible circuit board is formed on the PC plastic sheet by suction molding, and the window 12 is more conducive to the temperature detection of the thermistor.
[0020] A connector is also installed on the flexible circuit board. The connector is welded to the corresponding designed pad on the flexible circuit board and is used in conjunction with the connector on the designed BMS system, that is, the male and female terminals are plugged together to complete the information connection and transmission between the battery pack and the BMS system.
[0021] The above embodiments are only used to illustrate the detailed scheme of the utility model. The utility model is not limited to the above detailed scheme, that is, it does not mean that the utility model must rely on the above detailed scheme to be implemented. Those skilled in the art should understand that any improvement to the utility model, equivalent replacement of various raw materials of the utility model product, addition of auxiliary components, selection of specific methods, etc., all fall within the protection scope and disclosure scope of the utility model.
