This paper explores the challenges in the charging industry, particularly in the context of electric vehicles (EVs). It examines the current status of DC, AC, and wireless charging, revealing that DC fast-charging has a power range of 50-180kW, while ultra-fast charging exceeds 250-350kW. AC charging piles are crucial for daily energy replenishment, while wireless charging achieves efficiency close to wired charging but faces promotion obstacles. The study also highlights the diversified operation modes of charging facilities. Challenges include power grid impact, unbalanced layout, insufficient power access, and low return on investment. The paper proposes solutions and predicts development trends, predicting a shift towards high-power ultra-fast charging and intelligent Vehicle-to-Grid (V2G), upgrading infrastructure towards balance and intelligence, and shifting the market focus to “operationcentric” with capital concentration and diversified business models. This research aids in planning, policy-making, and enterprise operations in the charging field, contributing to EV promotion and carbon neutrality goals.
