Integrated overview: the fast charging pile (plug) equipment adopts the AC/DC integrated structure. It can realize both DC charging and AC charging. When there are many charging services in the daytime, DC mode is used for fast charging. When there are few users in the charging station at night, AC charging can be used for slow charging. Appearance features: 1. Ergonomic design, taking full account of Chinese characteristics, after installation, the height of the whole machine, the height of the screen, the height of the keyboard, and the height of the charging connector slot are suitable for operation; 2. The form of upper outlet saves half of the operator's physical strength; 3. In consideration of people's usage habits and durability, touch and keyboard are mutually backed up. Touch screen and keyboard are designed to be rain proof and dust-proof; 4. Emergency stop switch with emergency stop; The charging connector placement slot is waterproof; 5m long flexible cable.

3. Power requirements: ① Input voltage: single-phase 220V; ② Output power: single-phase 220V/5KW; ③ Frequency: 50Hz ± 2Hz; ④ Allowable voltage fluctuation range: single-phase 220V ± 15%; 4. Electrical requirements: ① After the correct connection of plug and socket is confirmed to be successful, the circuit that can be opened and closed with load can be closed to supply power to the socket; ② The leakage protection device shall be installed on the incoming side of the power supply cable; ③ The protection of low-voltage distribution equipment and lines shall meet the relevant provisions in the Code for Design of Low Voltage Power Distribution (GB/50053); ④ For the distribution line of IT system, in case of ground fault, the insulation monitoring device shall send out audio or light signals. In case of the second phase to phase ground fault, the fault circuit shall be cut off by the over-current protection appliance or leakage current action protector; ⑤ In the lighting distribution system, the lighting and socket circuits should not be powered by the same circuit.

In addition, according to the different ways of energy conversion when charging the electric vehicle battery, charging devices can be divided into contact type and induction type. With the rapid development of power electronics technology and converter control technology, the maturity and popularization of high-precision controllable converter technology, the phased constant current charging mode has been basically replaced by the constant voltage current limiting charging mode with continuous changes in charging current and charging voltage. The constant voltage current limiting charging mode dominates the charging process. The big problem of contact charging is its safety and versatility. In order to make it meet the strict safety charging standard, many measures must be taken in the circuit to enable the charging equipment to charge safely in various environments. Constant voltage current limiting charging and phased constant current charging are both contact charging technologies. New induction charging technology for electric vehicles has developed rapidly.

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.

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.
