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.

As a green means of transportation with broad development prospects, the popularization of electric vehicles will be extremely rapid in the future, and the future market prospect is also extremely huge. In the context of the global energy crisis and serious environmental crisis, the Chinese government actively promotes the application and development of new energy vehicles. As an important supporting infrastructure necessary for the development of electric vehicles, the charging/changing station has very important social and economic benefits. A campaign to build an electric vehicle charging/changing station has been launched nationwide. The overall system consists of four parts: electric vehicle charging pile, concentrator, battery management system (BMS), and charging management service platform.

The function of the charging post is similar to that of the gas dispenser in the gas station. It can be fixed on the ground or wall, installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations, and can charge various types of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected with the AC power grid, and the output end is equipped with a charging plug for charging the electric vehicle. Generally, the charging pile provides two charging methods: conventional charging and fast charging. People can use a specific charging card to swipe the card on the human-computer interaction interface provided by the charging pile to print the corresponding charging method, charging time, cost data and other operations. The charging pile display screen can display the charging amount, cost, charging time and other data.

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.
