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 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.

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.

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.

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.
