Industry jargon

Power Line Communication

Also called: PLC Power Line Communication, or PLC, carries digital data over conductors that also have an electrical power function. In wired ISO 15118 charging, PLC provides the data link used for high-level communication between the EV and EVSE. ISO 15118-3 defines physical and data-link requirements for wired high-level communication in addition to the basic charging signalling. CCS implementations commonly use HomePlug Green PHY technology for this PLC link. PLC is the communication medium at the charging interface. The ISO 15118 application messages carried over it are a separate layer of the system.
