Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to a CCS component structure. Background Art

[0002] Energy storage batteries are generally composed of multiple battery modules, and each single battery module corresponds to a CCS (Cells Contact System, acquisition and integration component). The existing CCS structures are usually busbar + PCB board + hot-pressing film or busbar + FPC + hot-pressing film. For the busbar + PCB board + hot-pressing film structure, due to the excessive hardness of the PCB board, its resistance to expansion and anti-vibration ability are poor. In actual applications of the CCS component, since the battery cells in the battery module will expand to a certain extent, the use effect of the busbar + PCB board + hot-pressing film structure is poor. For the busbar + FPC + hot-pressing film structure, the cost of FPC is too high, increasing the production cost of the battery module. Content of the Utility Model
