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;

After the completion of charging piles in some places, operation and maintenance become a problem. On the one hand, the number of urban public charging facilities is small, and the distribution is uneven and unreasonable; On the other hand, the management service platforms of the charging infrastructure construction and operation units have not yet achieved interconnection, nor has there been a unified, open and convenient payment platform, which has caused great inconvenience to charging infrastructure users. In addition, in the development process of new energy vehicle industry, there is a widespread problem of focusing on vehicles rather than charging infrastructure. In addition, the national early support policy is mainly aimed at new energy vehicles and does not cover charging facilities. Except for a few cities, most cities have no local subsidies. "This leads to the coexistence of vehicles without piles and piles without vehicles." Moreover, charging infrastructure construction involves urban planning, construction land, distribution network construction and transformation, property management and other aspects, and it is necessary to coordinate multiple competent departments and relevant units in the implementation process.

DC piles are the inevitable choice of public piles in the future: at present, the proportion of public AC and DC charging piles remains around 6:4, and the proportion of AC piles is more, mainly because in the early stage of the industry development, slow charging AC piles are very suitable for manufacturers to seize the market, relying on the characteristics of simple structure, mature technology and low cost, However, after the technology and market of charging piles become mature, DC piles are the inevitable choice for future public charging piles. The average charging time of the DC charging pile is 1 hour and 54 minutes. 85% of the users can finish charging within 2.5 hours, while the average charging time of the AC charging pile is 5 hours and 45 minutes. 66.2% of the users need more than 5 hours of lengthy charging time. The difference between the two nearly 4 hours of time directly determines the obvious use preference of the car owner Z.

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.

In fact, in order to effectively develop the new energy vehicle industry, in addition to the problems exposed in the construction of charging piles, such as difficult site selection, power connection and property coordination, the integration of infrastructure resources, the unification of public charging facilities information platform, the standardization of charging interfaces, and the billing and settlement in the charging process also need to be solved. The charging infrastructure of new energy vehicles is a new type of urban infrastructure. Its construction is a systematic project involving land, power grid, electricity price, mechanism and many other links, which is also the reason why the charging infrastructure construction is relatively difficult. However, as long as the relevant parties meet each other and reach consensus, instead of talking to themselves and going their own way, these problems will eventually be solved.
