Abstract
The limited range of plug-in electric vehicles - both battery and plug-in hybrid electric vehicles - is a crucial factor of the vehicles - utility and user acceptance. We compare the impact of three means to increase the effective range an electric vehicle can drive during one day: the size of the battery, the vehicle's efficiency in terms of electricity consumption per kilometer and recharging between trips using public charging infrastructure. As means to increase efficiency, we analyze variations of the vehicle mass, the impact of regenerative braking and a lower aerodynamic drag. The efficiency of the vehicles powertrain is assumed constant. We use real-world driving profiles to simulate individual driving behavior and real-world fuel and electricity consumption. Our findings indicate that weight reduction and an increased battery capacity offer noteworthy potentials to reduce electricity consumption and to increase the share of vehicles that could cover all their daily driving with a BEV.
