Operating Strategies for a Range Extender Used in Battery Electric Vehicles

Range extenders are claimed to be the enabler for electric mobility. They offer the possibility of reducing the battery capacity and therefore the system costs. Furthermore, they can ease the range anxiety. The overall system performance is determined by the operating strategy. In this paper, a simulation model of an electric vehicle with a range extender is described. The model is used to analyze three different operating strategies regarding fuel consumption and battery aging.
