Abstract: Electric Vehicle Service Equipment (EVSE) and Electric Vehicle (EV) are disclosed n. In an example embodiment, a modem is coupled to the pilot wire that couples the EVSE and the EV. The modem transmits both pulse width modulation (PWM) command signals and power line communication (PLC) signals to a remote device via the pilot wire. The modem interleaves the PWM and PLC signals on the pilot wire so that latency requirements for the PWM signals are maintained. The modem supports 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. The modem may create a modified frame for the PLC signals to maintain the latency requirements.
