Abstract: Limited electrical range is one of the main drawbacks of battery electric vehicles. Especially at low temperatures the range is reduced due to low battery capacity and power as well as additional energy demand for auxiliaries. A model based approach was chosen to compare different battery technologies regarding their in-vehicle performance. Several battery technologies were modeled and implemented into a simulation environment for vehicle systems. In addition, varying test cases were defined to analyze the battery characteristics and impact on the vehicle performance. Simulation results show that the energy demand of the power train rises significantly in urban surroundings and low ambient temperature conditions. The recuperation of brake energy is limited by the reduced battery power capability. Furtheremore, the efficiency of the battery and the power train was analyzed regarding varying temperatures, battery sizes and driving cycles. Finally, the electrical range was studied taking into account different driving cycles, temperatures, and auxiliary loads.
