Engineers at the University of California, Riverside (UCR) have developed a new online energy management system (EMS) based on an evolutionary algorithm for plug-in hybrid vehicles (PHEVs) that they say can improve PHEV fuel efficiency by more than 30%. Broadly, existing EMS for PHEVs are either rule-based or optimization-based.
