Under the severe situation of world oil resource shortage and global warming, the construction of low-carbon vehicles will become a new development direction of the automobile industry. Electric vehicle charging facilities are an important part of the electric vehicle industry chain that cannot be ignored. At present, AC charging piles, as special charging interfaces, provide AC power for electric vehicles with on-board chargers, which is an important basic support system for electric vehicles, and an important link in the process of the commercialization and industrialization of electric vehicles, so while vigorously developing the electric vehicle industry, charging facilities should also be taken into account adequately. development, so it is necessary to study the management scheme of electric vehicle charging pile.
