Firstly, let's take a look at who builds the charging piles for new energy vehicles. Most of the charging piles on the market are still built by State Grid Corporation of China, as they have the inherent conditions for circuit laying and approval of construction. At the same time, due to national policy requirements, State Grid Corporation of China is the first to bear the brunt, and early approved charging pile construction is basically completed by them. In addition to State Grid, it is the charging stations built by charging operators. In order to complete the construction task and later operation, State Grid will cooperate with some charging operators to build charging stations to meet the demand. The charging stations built by these two companies account for almost 90% of the total number of charging stations in the market. Another part is self built by manufacturers, and the quantity of this part is very small, but it is mainly used for household charging piles, and most of them have signed agreements with consumers.

Secondly, let's take a look at the brands of charging stations available. The dominant charging pile brands in the market now have their own characteristics, with differences mainly in the specifications of charging plugs, charging power, and charging time. However, not all brands of charging piles can meet consumers' charging needs.

Then, let's take a look at how to choose charging stations on the market for charging. The current charging interfaces for new energy vehicles are divided into Combo sockets, Mennekes fast charging sockets, CEE standard charging, and other interfaces. Some charging stations are even one per vehicle, which can only meet the charging needs of one vehicle model, resulting in a mixed situation of charging interfaces. When purchasing new energy vehicles, we should try to choose a unified standard charging interface, which is also for the convenience of future use.

Overall, in order to choose a satisfactory charging station, the main thing is to choose a big brand and a unified standard charging socket, so that it is comfortable to use and has a better experience.
