Communication on a Pilot Wire

摘要: Systems and methods are disclosed for communicating on a pilot wire between Electric Vehicle Service Equipment (EVSE) an (EV). The EVSE EV exchange Pulse Width Modulation (PWM) signal the to control charging operations of EV. Data communications may also be transmitted wire, such as transmit receive modems. modems communication signals either continuously, without regard state PWM signal, or only when is in off-state. If transmitting while on, modem needs large coupling impedance and/or injection. To off, use blocking diode circuit synchronize pulses signal.
