We analyze daily charging demand patterns of electric vehicles at DC fast charging stations along the
German autobahn for an average week in 2020. For this we develop an agent based simulation tool based
on current empirical mobility data. Our results show that already in 2020 about 1,000 charging processes
per charging location and day might be realistic. In order to avoid long waiting times these charging
locations should be equipped with about 20 charging points. A utilization rate of up to 80% makes a
profitable operation of these stations highly probable. A sensitivity analysis indicates main parameters
which influence the throughput of electric vehicles significantly.
