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.

Both the mileage and the number of charging posts have made great progress over the previous years. According to the reporter, at present, the driving range of the mainstream models of new energy vehicles and passenger vehicles in China has reached more than 300 kilometers, which is in line with the international advanced level. The energy density of the single power battery of the leading enterprise has reached 2 watt hours per kilogram, and the price has reached 1.2 yuan per watt hour. These two indicators have respectively increased by two times and decreased by 70% compared with 2012. At the same time, the construction of charging network is progressing steadily, and the coverage of public places, residential quarters, internal units, highways and other major places is increasing significantly. By the end of 2017, 214000 public piles had been built nationwide, an increase of 51% year on year, ranking first in the world in terms of ownership, and the installation rate of new users' private piles exceeded 80%.
