Description

Technical Field

[0002] With the rapid development of new energy vehicles, power batteries are essential components, and their safety remains a critical issue. Currently, integrated busbars (Cells Contact System, CCS) use flexible printed circuit boards (FPCs) to collect and transmit electrical signals such as voltage, current, and temperature, integrating fuses onto the FPC. This is because fuse functionality can be easily implemented on FPCs; however, FPCs are relatively expensive.

[0003] When using lower-cost flexible flat cables (FFC) or wire harnesses to collect and transmit electrical signals, fuses cannot be integrated, and the entire CCS lacks fuse functionality. This results in less effective thermal management of the battery pack, and the circuit cannot be promptly cut off by a fuse in case of abnormal current.

[0004] Therefore, there is an urgent need to develop a cell connection aluminum bar structure and battery pack with a safety function, including terminals and a safety device. Utility Model Content
