Texas Instruments (TI) leading power line communications (PLC) technology has enabled Cygnus Electronics to create a PLC hardware and software platform designed for automotive qualification in electric vehicles. Auto-rem implements the Society of Automotive Engineers’ (SAE) J2931-3 specification, which is a narrowband orthogonal frequency division multiplexing (OFDM) proposal for plug-in electric vehicle (PEV) to electric vehicle service equipment (EVSE) communications during PEV battery charging. J2931-3 is based on the upcoming IEEE P1901.2 international narrowband OFDM standard. The auto-rem system uses a TI PLC chipset comprised of an optimized OFDM C2000™ Piccolo™ microcontroller (TMS320F28069) and an integrated analog front end AFE031, which integrates more than 100 discrete devices.
