First check whether the electric vehicle wire is connected, check the diameter of the positive and negative terminals, and then the other side of the number: on the car according to the instructions on the path: CD CD- is the positive and negative terminals of DC charging, A A- is the positive and negative of the low-voltage auxiliary power supply, S ten S one is the CAN communication line, CC1 CC2 is the charging connection confirmation, PE is the ground.
After connecting the link charging pile to charge the car to check whether the line is connected or whether the interface is loose
