Electric vehicles (EVs) and their application raise new questions and demands. Accordingly, the charging process of electric vehicles is a novelty in everyday life when using such vehicles. This paper presents results of user charging behavior within a field test. In the field test, 500 people with above average yearly mileage took part in integrating the vehicles into their everyday lives. The differences in user behavior between purely electric (BEV) and extended range electric vehicles (EREV) are discussed. Additionally, the opportunities and limitations for vehicles with combined grid services appear from the results as well as the resulting grid load. The results indicate that the vehicles are parked close to a charging station the majority of the time. The results also show deviating user behavior for the BEVs and EREVs.
