ABSTRACT: Driven by the dual goals of global carbon neutrality and the transformation and upgrading of the automotive industry, electric vehicles have become a strategic core area for addressing climate change and ensuring energy security. This article systematically reviews the research progress in the field of electric vehicles, focusing on five mainstream research directions: power battery technology, optimization of electric drive systems, intelligence and autonomous driving, lightweight and material innovation, charging and swapping, and energy interconnection. It comprehensively analyzes the technological breakthroughs, application status, and existing bottlenecks in various fields. Research has shown that high-energy density solid-state batteries, silicon carbide electric drive modules, Level 3 or above autonomous driving, integrated lightweight technology, and V2G energy interconnection systems are current and future core research hotspots. Finally, based on the needs of industrial development, the future research focus and development path of electric vehicle technology were discussed, providing a reference for academic research and industrial practice.
