An electric power service worker helps a car owner to charge a new-energy vehicle by scanning codes on a cellphone at a "car grid interaction" smart microgrid charging station in Nantong in East China's Jiangsu Province on May 12, 2025. Jiangsu's first rural "car network interaction" smart microgrid was recently installed in Nantong, which is conducive to alleviating the challenges of a relatively poor charging facility base in rural areas and maintaining a stable supply of rural electricity.
