The electric vehicles, which were integrated into two different fleet use cases, were equipped with measurement equipment to gain knowledge about energy consumption and usage profiles. For each vehicle type the energy consumption is divided into powertrain and auxiliary energy consumption and an overall as well as a monthly evaluation is performed. Main aspect of the usage profiles are the travelled distances, trip durations, share of different road types and environmental conditions. To get additional knowledge about the energy consumption under different conditions, like ambient temperature or another share of road types, or vehicle configurations a full vehicle simulation was established. By creating models for each component of the powertrain and also modeling the air conditioning system as well as the passenger cabin, a modular simulation model was achieved. For each vehicle type only a new parameterization was needed. A validation of the simulation was performed by using the measurement data of the vehicles as well as tests on a test bench.
