Description

Technical Field

[0002] With the rise of new energy vehicles, the components used in conjunction with new energy vehicles have also developed; among them, the CCS (Cruise Control System) component is an important component of the power battery module, mainly playing the role of power transmission, signal acquisition and battery management. The rapid development of new energy vehicles has put increasingly stringent requirements on the automated production, reliability and safety of automotive components. As a major component of new energy vehicles, the power battery CCS component plays a key role in the safety of the battery module and real-time detection of the battery module status.

[0003] The traditional CCS assembly consists of a Busbar assembled on a blister isolation plate, which is fixed by hot riveting. The FFC board body is fixed to the blister isolation plate by pasting, and the FFC board pins are welded to the Busbar. The FFC board pins need to be separated from the main body, and the outer sheath of the circuit is easily torn during the separation process, resulting in metal leakage and short circuit. The FFC board pins need to be separated into different lengths according to the different welding positions of the Busbar, and bent 90 degrees to the welding position. The bending process cannot be automated, and the bending accuracy is poor, which affects the position consistency of the Busbar welding. When the FFC board pins are directly welded to the Busbar, they are limited by the weldable area; the pull-out force and peeling force values ​​after welding are low, and the reliability and stability are poor; and the FFC board circuit cannot be equipped with fuses and NTC temperature acquisition components, and the function is single, which cannot meet the safety performance and battery cell monitoring requirements in the power battery system.
