With the promotion of pollution and carbon reduction and the construction of a Beautiful China, the transformation of transportation electrification is accelerating. Improving cruising range and accelerating energy replenishment efficiency have become two key technological development directions. Countries have invested in the research and development of a series of technical standards for megawatt-level fast charging, and have also conducted pilot explorations for the industrial development of megawatt charging technology. This article first introduces the megawatt-level fast charging technology system, summarizes the current status of international megawatt-level charging standards, and introduces the latest progress in product development and pilot work in the field by governments, enterprises and other organizations from the perspective of market development; Finally, based on the current development status of domestic charging technology and market, combined with the development experience of international megawatt-level charging, relevant suggestions are put forward from the aspects of standards, industry, policy and other aspects.
