The control circuit of the electric vehicle charging pile (plug) is mainly completed by the embedded ARM processor. Users can swipe their cards to carry out user authentication, balance query, billing query and other functions, and can also provide voice output interface to achieve voice interaction. The user can select four charging modes according to the indication of the LCD screen: charging on time, charging according to the quantity of electricity, automatic charging, charging according to the mileage, etc. The electric vehicle charger controller and concentrator use CAN bus for data interaction, and the concentrator and server platform use wired Internet or wireless GPRS network for data interaction. For security reasons, the electricity billing and amount data are encrypted securely.

Miao Wei, minister of the Ministry of Industry and Information Technology, said at the China Electric Vehicle Hundred Talents Forum (2018) that the current vehicle to pile ratio of 3.5:1 across the country still cannot meet consumers' demand for charging. With the continuous growth of the number of new energy vehicles, the problem of insufficient structural supply of charging infrastructure has become increasingly prominent, and the overall scale is still lagging behind. In 2020, China plans to build about 500000 public charging piles. However, compared with the annual production and sales of 2 million vehicles and 5 million vehicles in the 2020 plan, the number of charging piles still does not match, and the vehicle pile ratio even tends to deteriorate. In addition, the layout of charging facilities in China is also not reasonable. The utilization rate of public charging piles is less than 15%. A sustainable business development model has not yet been formed. There is still a two-way contradiction between operating enterprises' profitability difficulties and consumers' high charging prices.

The country attaches great importance to the development of new energy vehicle charging equipment, and all regions will naturally increase efforts to promote development. Taking Nanning as an example, it is estimated that by 2020, there will be about 21550 new energy vehicles in Nanning. In order to meet the charging needs of the majority of car users, by 2020, Nanning will need nearly 20000 charging poles and nearly 100 charging stations. At present, the development of electric vehicle public charging equipment in Nanning is still in the primary stage. At present, the number of electric vehicles and the number of charging piles are seriously unbalanced, and the phenomenon of vehicles without piles and piles without vehicles occurs from time to time. The main reason is that the all smart service platform has not been built yet and needs further improvement.

When the charging post is built, it should be used and managed well. The implementation of management responsibility and clear operation mode can make the charging pile safe and reliable. At present, the charging pile is faced with the problem of unclear management responsibility and unclear operation mode. There are some problems such as the aging of distribution facilities in the community, who will pay for the reconstruction, the quality of piles is mixed, and who will solve the hidden fire hazards. The same is true of public charging posts. There are not many DC fast charging piles with high investment standards and high power, but "problem piles" and "zombie piles" are common. In recent years, the number of charging pile construction and operators in China has grown rapidly, but the level of enterprises is uneven.
