The travel demand model mobiTopp is used to analyse the effects of an increasing fleet of electric vehicles on the electricity demand. For this purpose mobiTopp has been extended to support EVs. These extensions comprise an EV ownership model, different types of EVs, namely Battery Electric Vehicles (BEVs) and Extended Range Electric Vehicles (EREVs), the charging process of EVs, and modified travel behaviour for persons using BEVs. The model is used to simulate the electricity demand for charging of EVs in the Greater Stuttgart Area over a period of one week. The daily electricity demand for EV charging contains a distinct peak around 6 p.m. for each workday and an additional morning peak around 8 a.m. when recharging at the workplace is possible. This additional electricity demand is concentrated in zones with residential use during the evening peak and in zones with office/industrial use during the morning peak.
