A: What are the respective functions of cc and cp of AC charging interface?
N is the two cables connected to our household 220V.
The \"cable control box\" detects whether the voltage is 12V through CP detection points 1 and 4. If it is not connected, the detection point 4 will not be connected, and the voltage will not be detected, if the connection is good.
The detection point 4 is connected with the vehicle through the PE, and the voltage is 12V, and the \"cable control box\" will make S1 and PWM connected after 12V electricity, otherwise S1 is connected with 12.
