Exploring Heterogeneous Electric Vehicle Charging Behavior: Mixed Usage of Charging Infrastructure

This paper examined charging behavior of 7,979 plug-in electric vehicle (PEV) owners in California, focusing on their mixed usage of level 1 (L1), level 2 (L2), and DC fast chargers at different locations. Unlike most of the current models and simulations used to characterize electric vehicle charging, the authors identified different day of week charging behavior among different types of PEV owners. The authors were also able to classify seven different groups of charging behaviors based on mixed usage of charging locations, and identify factors associated to the heterogeneous charging behavior. The authors found socio-demographics, vehicle characteristics, commute behavior, and workplace charging availability as significant factors driving charging behavior. Among these factors access to workplace charging was the most important one.
