In electromobility, the Power Line Communication PLC is used for the communication of important data between the electric vehicle EV and the charging station EVSE. The data is transmitted via the so-called Control Pilot CP using an OFDM orthogonal frequency division multiplexing method. This means that the data is transmitted via higher frequencies that are modulated onto the existing pulse width modulated PWM signal. The PLC can be encrypted or unencrypted depending on the configuration.
