The new energy vehicle (NEV) market is undergoing transformative changes in consumer demand, shifting from mass-produced uniformity to personalized/customized designs in both aesthetics and performance. This evolution is driving a fundamental transition in production models - from traditional high-volume/low-variety manufacturing toward future-ready low-volume/high-mix systems characterized by rapid iteration cycles. Consequently, emerging technologies must now deliver diversified, flexible and intelligent production processes to meet these dynamic requirements.
