Claim Text:
1. An electric vehicle service equipment (EVSE), comprising: a pilot wire to couple the EVSE and an electric vehicle (EV); a controller configured to communicate with the EV using PWM signals on the pilot wire; and a modem coupled to the pilot wire, the modem providing an interface between controller and the pilot wire, the modem operating to transmit both pulse width modulation (PWM) command signals and power line communication (PLC) signals to a remote device via said pilot wire, the modem interleaving the PWM and PLC signals on the pilot wire so that latency requirements for the PWM signals are maintained, wherein the modem supports a plurality of parallel protocol stacks in which PLC signals are processed in a first path and PWM signals are processed in a second path that bypasses the first path and provides the PWM signals directly to a MAC layer.
