DC type: a) Power input voltage of charging pile (plug): three-phase four wire 380VAC ± 15%, frequency 50Hz ± 5%; b) The charging pile (plug) shall meet the charging object; c) The output of the charging pile (plug) is DC, and the output voltage meets the battery system requirements of the charging object; d) Zui's large output current meets the charging requirements of battery system 1C of the charging object, and is downward compatible; e) The charging mode can be divided into conventional and fast charging modes. The conventional charging mode is 5-hour charging mode, and the fast charging mode is 1-hour charging mode (selected for different battery types); f) Realize intelligent IC management; g) Each charging pile (plug) is equipped with an operator for the user to select charging mode and guide operation, and display the battery status of electric vehicles and the user's IC card charge information to achieve unattended management;

With the progress of people's life, consumers' requirements for cars are getting higher and higher, especially new energy vehicles. When consumers buy new energy vehicles, the first thing they should pay attention to is the battery and endurance of new energy vehicles, and then the charging of cars. Today, I will tell you about the charging pile of new energy vehicles. Is it GM? According to Xu Xinchao, the core of the charging national standard revision plan expected to be officially released in August this year is to standardize and unify the charging piles of new energy vehicles, and the charging sockets of different models will be unified.

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.

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.

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%.

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.
