The Charging station provides three charging modes: 1) ordinary charging, that is, conventional charging or slow charging. This mode is mostly AC charging, which is mainly completed by the Charging station. The external 220V or 380V AC power supply is connected to the on-board charger, and the on-board charger charges the power battery. Generally, small pure electric vehicles and hybrid vehicles often use this method. 2) High current fast charging, also known as fast charging. It is necessary to build a fast charger, which is mainly achieved by the ground charger of the charging station, without passing through the onboard charger, directly charging the onboard battery. Electric vehicles only need to provide charging and related communication interfaces, and can be charged to 50% to 80% within 20 to 30 minutes without fully charging, meeting the range needs. 3) Battery replacement is a faster and more convenient method, simply remove all the power battery modules of the electric vehicle and replace them with fully charged battery packs of the same model. Due to the involvement of charging, storage, maintenance, and replacement of battery modules, higher standards are required for the construction of charging stations.

As the energy supply device of electric vehicle, the charging performance of electric vehicle Charging station is related to the service life and charging time of the battery pack. This is also one of the aspects that consumers are concerned about before purchasing electric vehicles. The basic principle of designing electric vehicle chargers is to achieve fast, efficient, safe, and reasonable power supply for power batteries. In addition, the applicability of chargers to various power batteries should also be considered. The scheme of the charger in the ground charging station is composed of a rectifier that can convert input AC power into DC power and a power converter that can adjust DC power. By inserting a plug with wires into the matching socket on the electric vehicle, DC power is input into the battery to charge it. The charger is equipped with a locking lever to facilitate the insertion and removal of the plug, and the lever also provides a signal to confirm that it has been locked to ensure safety. According to the communication between the charger and the Battery management system on the vehicle, the power converter can adjust the DC charging power online, and the charger can display the charging voltage, charging current, charging amount and charging cost. This is just the basic principle of the Charging station. Many details should be constantly improved in practical application, and a convenient use scheme has been obtained.

The strong support and promotion has stimulated many enterprises' expectations for the Charging station industry. In addition to energy companies such as the power grid, China Southern Power Grid, and Sinopec, automotive and electrical production enterprises are all highly motivated. Electric vehicle enterprises such as BYD and BAIC have already begun to build general Charging station, and * * * enterprises such as XJ Electric and Siemens have also begun to develop or invest in the construction of charging stations. According to relevant calculations, the operating scale of charging stations is expected to exceed 100 billion yuan per year in the next five years
