The clips used in electric vehicle (EV) battery enclosures are critical for securing components and ensuring safety, yet they have received limited research focus compared to the main enclosure structure. This work addresses this gap by presenting a comprehensive methodology for the topology optimization and durability analysis of these clips. The optimization was conducted using the SIMP (Simplified Isotropic Material with Penalization) method. The raw optimized geometry was then refined to create a manufacturable design suitable for progressive die stamping, adhering to constraints such as uniform thickness. A finite element analysis (FEA) was performed under various static loading scenarios (33 N, 67 N, and 100 N) to validate the design. Durability was quantified using the dimensionless stress ratio σA/σYS. The key accomplishment is that the final optimized clips (with a 0.7 mm thickness) demonstrated a 36.96% improvement in durability (i.e., a lower stress ratio) compared to the base clips under the same load condition.
