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.

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.

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.
