The rapid promotion and widespread application of electric vehicles necessitate the continuous development and layout of charging infrastructure to continuously optimize the charging conditions for electric vehicles. In the county-level scenarios for promoting electric vehicles, it is essential to build supporting charging infrastructure. The rational layout of charging infrastructure, the efficient and reasonable use of the limited power capacity of the power grid, the reduction of impact on the power grid, and the provision of higher quality and more stable electrical energy input to electric vehicles are key issues that need to be studied for the long-term and healthy development of charging infrastructure. Energy storage can effectively reduce the pressure on the distribution network, peak shaving and valley filling, reduce the impact on the power grid at the electricity consumption end, and at the same time, improve the power quality and increase the reliability of electricity use. Combining energy storage systems with charging piles can effectively help promote charging infrastructure. An in-depth discussion on the technical significance and value of integrated energy storage and charging piles in different scenarios is required. Integrated energy storage and charging piles have characteristics such as modular integration, minimal demand for power capacity expansion, and low requirements for civil construction. They act as “pioneering explorers” in remote areas, fourth and fifth-tier cities, townships, and transportation lines where charging infrastructure is not well developed. They serve as “charging power amplifiers” in areas with scarce power capacity, “voltage stabilizers” in areas with poor power grid quality, “virtual capacitor dispatchers” for temporary power capacity expansion, “regional emergency power supplies” for micro power stations, and “beachhead soldiers” for the international promotion of China’s new energy vehicle charging standards, new energy vehicles, and charging equipment in the overseas market. Analyze its application scenarios in remote areas and fourth and fifth-tier cities, areas with difficult power capacity expansion, tidal charging demand scenarios, and overseas markets. The industry should pay attention to the promotion and application of integrated energy storage piles, strengthen technology research and development, formulate relevant policies, encourage enterprises to invest in construction and operation, and help promote the internationalization of Chinese standards and the comprehensive development of the new energy vehicle industry.
