Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, and in particular to a CCS integrated component, a battery module, and a battery pack. Background Technology

[0002] Currently, in battery manufacturing technology, CCS integrated modules are a system integration solution that integrates numerous functions and has wide applications in electric vehicles and energy storage. These CCS integrated modules mainly include: separators providing a load-bearing foundation, signal acquisition components for collecting battery information, and busbars for forming high-voltage series / parallel connections between batteries.

[0003] In existing technologies, common CCS integration solutions use separators that employ vacuum forming or flame-retardant PC sheets, but these thin structures generally have relatively poor dimensional accuracy and load-bearing capacity. This means that when installing the output busbar of the battery module, the high-voltage base used for mounting the output busbar still needs to be fixed to the end plate of the battery module and the box beam structure of the battery pack. Especially when the battery module's insertion precision is low, the assembly tolerance between the output busbar and the high-voltage base is also large, reducing the bolt tightening area and lowering the current-carrying capacity and mechanical safety of the high-voltage copper busbars between modules.

[0004] In addition, when the signal acquisition components in the existing CCS integration solution are integrated onto the isolator, the parts connected to the connectors are prone to bending and deformation, which can lead to stress concentration and failure after long-term use.
