Battery Cell Contact Layout With FFC Buffer Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The flexible flat cable (FFC) in battery contact systems is prone to breaking due to external forces, which affects battery life as it needs to be bent to connect to busbars and is squeezed by the battery's upper cover and support.
Innovation Solution
A cells contact system with a support featuring an opening corresponding to the bent portion of the acquisition line, providing a buffer space to reduce the risk of breakage when an external force is applied.

Engineering Contradiction Analysis
1Volume of moving object
If the upper cover and support are positioned close together, then the battery structure is compact, but the bent portion of the acquisition line is squeezed and may break
Solution Approach 1:
The support structure has different local properties: areas away from the acquisition line provide structural compactness, while the area at the bent portion provides cushioning or increased spacing. This localized quality differentiation allows the battery to maintain compact overall volume while protecting the acquisition line at the critical bent location from squeezing forces.
