This paper introduces an integrated design approach for electric vehicles (EVs) to enhance cooling and crashworthiness performances simultaneously. The proposed design incorporates an origami sandwich structure (OSS) within a battery module consisting of three cells connected in series. The study explores the effects of the folding angle (0) on the performances, and it is revealed that implementing OSS-based cooling channels with θ=40° results in a reduction of maximum temperature by 4.3°C under 5C fast discharging condition and a remarkable improvement in peak crushing force and impact energy absorption compared to a flat channel. Moreover, the performances can be further improved with the rising folding angle (0). A comparison of different origami channels and a flat channel from various perspectives indicates that the origami channel with a folding angle of 20° or 30° yield the most optimized designs.
