The increase of power battery capacity of new energy vehicles: the fast charging performance of the power battery determines the ceiling of the fast charging pile. The development of DC fast charging pile requires the cooperation of the power battery. At present, battery manufacturers such as Ningde Times and BYD are trying to improve the energy density of batteries to enhance the endurance. In 2020, the energy density of new pure electric passenger vehicles has basically exceeded 150Wh/kg, and the average endurance mileage has exceeded 400km. The improvement of the endurance mileage of new energy vehicles has improved the practicability of high-power DC public piles, and accelerated the preference of vehicle owners for DC piles, which is the key reason why DC piles will become the choice direction of public piles in the future.

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.

Safety requirements (1) The substation shall be equipped with safety bulletin board, warning board, safety signal light and alarm bell. (2) The warning sign of "Stop, High Voltage Danger" shall be hung outside the door of the high-voltage distribution room and transformer room or on the safety column of the substation. The warning signs must face the outside of the fence. (3) There shall be obvious operation instructions on the high-voltage distribution device. The grounding point of the equipment shall have obvious signs. (4) There should be obvious signs of "safe passage" or "emergency exit" in the room. In addition, the layout design of substation and distribution equipment shall facilitate installation, operation, handling, maintenance, test and monitoring. High and low voltage distribution room, transformer room, capacitor room and control room should not have unrelated pipes and lines passing through. New energy vehicles should first focus on cities, but the busy IX region is often short of land, and the cost of land is high. In this regard, the government needs to give preferential policies to promote the construction of charging facilities. The development and operation of electric vehicle charging stations by electric power enterprises have inherent advantages.

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.

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.

There are four main pain points: A. Battery standardization is too difficult. The separation of vehicle and electricity first requires the standardization of power batteries, BMS standardization, interface standardization, and software management standardization. Any vehicle upgrade must be compatible with the previous generation of products. Battery standardization is too difficult. Every car company wants to make its own electricity exchange standard. It is unrealistic for so many car companies to unify. B. The investment is large and the cost is high. The replacement of power needs to lay a large network, and the investment scale is far greater than charging. Build a power exchange network for a city to provide special tram exchange services. The cost can be recovered only after at least 6-8 years or even more. C. The deflagration hazard of the power plant is large, and the safety hazard is huge. D. It is difficult to improve the customer experience.
