AC EV Charging Station Circuit Analysis

Analysis of AC Slow Charging Circuit

Grid power supply, also known as the charging station, has no interface between the charging station and the cable, which is a typical feature of connection method C.

Vehicle Coupler, which is the vertical dashed line in the middle of the vehicle interface, is the connection point between the charging gun and the electric vehicle charging port.

CC signal is used to determine the connection status between the charging gun and the electric vehicle, 

CP signal is used to transmit PWM signals, transmitting information through duty cycle and voltage magnitude. 

The charging station provides a PWM signal, and the voltage is controlled by the electric vehicle
