As a green means of transportation with broad development prospects, the popularization of electric vehicles will be extremely rapid in the future, and the future market prospect is also extremely huge. In the context of the global energy crisis and serious environmental crisis, the Chinese government actively promotes the application and development of new energy vehicles. As an important supporting infrastructure necessary for the development of electric vehicles, the charging/changing station has very important social and economic benefits. A campaign to build an electric vehicle charging/changing station has been launched nationwide. The overall system consists of four parts: electric vehicle charging pile, concentrator, battery management system (BMS), and charging management service platform.

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.

Although the proportion of new energy vehicles is increasing year by year, its absolute number is much less than that of fuel vehicles. According to the reporter, consumers are dissatisfied with new energy vehicles (mainly pure electric vehicles) mainly in the following two aspects: first, there are relatively few charging piles and charging time is long. Although it is convenient to install by yourself, it is an indisputable fact that in a big city like Beijing, there are only a few parking spaces of their own, and most of them are parked at the roadside. Second, the endurance mileage is not long enough. If you travel far, you will be in trouble once you cannot find the charging post. Chen Qingtai, president of the China Electric Vehicle Hundred People Association, believes that the basis for the rapid growth of electric vehicles is that the cost performance and convenience of electric vehicles should reach or exceed that of fuel vehicles. Therefore, in addition to technological progress, charging infrastructure construction must also keep pace.
