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.

Not only does China attach importance to the development of new energy charging equipment, foreign new energy companies are developing more rapidly, and French oil giant Total is also actively building charging equipment. In the early years, Total acquired Saft, a battery manufacturer. This company originally produced power batteries and provided automotive batteries for many automobile manufacturers. And some foreign companies have even developed wireless charging technology. They transmit wireless energy through magnetic induction between the charging coil and the receiver. The charging coil is buried under the ground. When it needs to be charged, just drive the car to an appropriate position to charge. New energy vehicles are very popular in recent years. Because of the environmental protection of new energy vehicles, many countries advocate new energy vehicles, and many people are interested in new energy vehicles. The New Energy Vehicle Technology Analysis has relevant content. Obviously, the trend of fuel vehicles has gone.

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.

Model diversification: many people find that there are more new energy vehicles running on the street today, and the models are more abundant. Is that the case? By visiting the stores of the three automobile enterprises mentioned above one by one, the reporter found that the product power of new energy vehicles has been greatly improved, and can intuitively feel the strong development momentum of the industry. In Tesla's Beijing Huamao Store, two Model 3 cars are in the middle, and Model Y and Model X of SUV models are on both sides. The three models have the same style, dynamic and fashionable appearance, and simplified interior. The center console has no other physical buttons except for the center control display. From the appearance, the products of the three new energy vehicle brands all have a prominent feature, that is, the design style is fashionable, which is obviously ahead of fuel vehicles at the same price, close to or even beyond international luxury brands. Under the new consumption feature of "beauty is justice", this alone has greatly enhanced the attractiveness of products.

In fact, in order to effectively develop the new energy vehicle industry, in addition to the problems exposed in the construction of charging piles, such as difficult site selection, power connection and property coordination, the integration of infrastructure resources, the unification of public charging facilities information platform, the standardization of charging interfaces, and the billing and settlement in the charging process also need to be solved. The charging infrastructure of new energy vehicles is a new type of urban infrastructure. Its construction is a systematic project involving land, power grid, electricity price, mechanism and many other links, which is also the reason why the charging infrastructure construction is relatively difficult. However, as long as the relevant parties meet each other and reach consensus, instead of talking to themselves and going their own way, these problems will eventually be solved.

When the charging post is built, it should be used and managed well. The implementation of management responsibility and clear operation mode can make the charging pile safe and reliable. At present, the charging pile is faced with the problem of unclear management responsibility and unclear operation mode. There are some problems such as the aging of distribution facilities in the community, who will pay for the reconstruction, the quality of piles is mixed, and who will solve the hidden fire hazards. The same is true of public charging posts. There are not many DC fast charging piles with high investment standards and high power, but "problem piles" and "zombie piles" are common. In recent years, the number of charging pile construction and operators in China has grown rapidly, but the level of enterprises is uneven.
