[0003] The conventional FFC busbar design is to connect the collected temperature sensor to the main line by crimping the terminal, which is not easy to carry out SMT patch and requires a lot of materials, which reduces work efficiency and increases costs. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a battery module busbar of an FFC solution, directly opening a window in the insulating layer of the FFC collection line, and directly pasting the temperature sensing components on the FFC line. This solution has a simple manufacturing process, greatly improves the operating efficiency, and also saves materials.

[0005] In order to solve the above technical problems, the utility model provides a battery module busbar of an FFC solution, characterized in that it includes a bottom plate, output-level aluminum bars are arranged on both sides of the bottom plate, series-connected aluminum bars are arranged between the output-level aluminum bars, and FFC collection lines are arranged on the bottom plate at the inner side of the series-connected aluminum bars; a PCB board is arranged on one side of the bottom plate, the FFC collection line is connected to the PCB board, and a connector is arranged on the PCB board.

[0006] Furthermore, an opening is provided on the bottom plate at a position corresponding to the output-stage aluminum bar.

[0007] Furthermore, a placement groove is provided on the bottom plate at a position corresponding to the serially connected aluminum bar.

[0008] Furthermore, a temperature sensing component is arranged outside the FFC collection line.

[0009] Furthermore, evenly arranged mounting holes are provided at the center of the bottom plate, and the mounting holes are in the shape of oblong holes.

[0010] The beneficial effects of the utility model are as follows: the bottom plate of the device includes a blister tray base; the output pole aluminum bar and the series aluminum bar are used for series-parallel module cells, and the FFC collection line is ultrasonically welded with the aluminum plate to collect voltage signals. Since the FFC collection line cannot be connected to the connector, a PCB board is used to connect the FFC collection line and the connector, and finally the voltage signal is transmitted to the BMS battery pack control system through the adapter harness. The temperature sensing components are welded on the FFC collection line by SMT patches to form a temperature collection loop, and the temperature signal is also transmitted to the BMS battery pack control system through the adapter harness. This solution has a simple manufacturing process, greatly improves the operating efficiency, and saves materials. BRIEF DESCRIPTION OF THE DRAWINGS
