With the rapid development of the new energy vehicle industry and accelerated urbanization, cities face dual challenges of “parking difficulties” and “charging difficulties”. This paper explores the theme of “coordinated development of smart parking and charging facilities”, aiming to analyze how technological innovation and management optimization can transform these two systems from isolated layouts to deep integration. The chapter first outlines key supporting pathways centered on IoT, big data, AI technologies, and V2G (Vehicle-to-Grid) technology, while summarizing typical collaborative models such as “park-charging integration” and “photovoltaic-storage-charging-discharge integration”. Finally, it proposes policy guidance, business model innovation, and technological innovation to promote efficient synergy between the two systems, enhancing the digitalization and sustainable development of urban transportation systems.
