With the gradual maturity of the entire new energy vehicle industry chain and the gradual release of market demand, the industry is about to erupt in 2018, but the problems of insufficient structural supply of charging infrastructure and the overall scale lag are increasingly prominent. It is urgent to make up for shortcomings and accelerate the construction of supporting infrastructure such as charging piles. How can we solve the problem of insufficient structural supply of charging infrastructure? Is there any successful case of innovative practice worth learning? There is a big gap in the charging pile. Under the global environment of resource conservation and green economy development, new energy vehicles are developing very rapidly. As the power guarantee of new energy vehicles, the charging pile is highly concerned by all circles. It can be said that the construction of charging infrastructure is one of the key factors affecting the promotion of new energy vehicles in China, and is more related to the development prospects of new energy vehicles.

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 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.

Charging every day: For many commuters, it may be enough to charge the car once every two or three days. However, some experts suggest that you should not try to save time and charge frequently every day, so that the battery can be in a shallow cycle state, which is more conducive to extending the service life. Pay attention to the phenomenon of poor contact between the plugs at both ends of the charging line: poor contact will lead to the heating of the plug, and once the heating time is too long, short circuit may occur, thus damaging the charger and battery. Therefore, the owner needs to check and replace the connector in time.
