CP = Control Pilot
CS = Connection Signal

CP :: 충전소와 전기차 간 통신을 가능하게 하는 양방향 통신선이다. 무엇보다도 충전소는 EV에 사용 가능한 최대 충전 전류를 알려줍니다.
Using a 1 kHz square wave at ±12 V between the CP and PE line provided by the EVSE,
the amplitude can be manipulated by the EV to control charging (PWM communication).
It is also used as a safety function. As soon as the CP connection is interrupted,
the charging voltage is switched off.
(*EVSE : Electric Vehicle Supply Equipment = 충전소를 의미함)
