First of all, the electric vehicle fast charge and slow charge interfaces are corresponding to DC and AC interfaces, DC fast charge and AC slow charge. Under normal circumstances, the fast charge interface is 5, and the slow charge is 7. In addition, it can also be seen from the charging line that fast charging and slow charging, and the fast charging line is relatively stronger. Of course, some electric vehicles have only one charging mode for cost, battery capacity and other considerations, so there will be only one charging port.

The principle of fast charge is to store direct current directly into the battery, and alternating current needs to be converted into direct current through the vehicle charger, which is stored in the battery, so the time will be much slower than the fast charge
Dc charging station: DC electric vehicle charging station, commonly known as \"fast charging\
The input voltage of DC charging pile adopts three-phase four-wire AC380V±15%, the frequency is 50Hz, and the output is adjustable DC, which can directly charge the power battery of electric vehicles.
Because the DC charging pile adopts three-phase four-wire power supply, it can provide sufficient power, and the output voltage and current regulation range is large, which can meet the requirements of fast charging.
