Individual motorized mobility is becoming increasingly electrified. The unique properties of electric vehicles promise to give rise to new collective traffic flow dynamics, which are largely unexplored as of now. Here we demonstrate a new type of congestion in the utilization of charging infrastructure, emerging solely from correlations in driver's charging dynamics due to queue-avoidance behavior on long range trips. We explain the formation of forward-propagating congestion waves as phase separation of the traffic flow into free and congested phases, occurring already before the system reaches its theoretical capacity limit. While current numbers of electric vehicles compared to available charging stations are far below the onset of congestion, these results reveal collective dynamics that may influence how future infrastructure supporting sustainable modes of mobility will be built.
