Identifying Heterogeneous Electric Vehicle Charging Behavior: Mixed usage of L1, L2, DC fast chargers at different locations-Presented at EVS 31 EVTeC 2018, Kobe, Japan, October 1 - 3, 2018

摘要

This paper examined charging behavior of 7,979 PEV owners in California, focusing on their mixed usage of L1, L2, DC fast chargers at different locations. We found different day of week charging behavior between different types of PEV owners. We were also able to classify seven different groups of charging behavior based on mixed usage of charging locations, and identify factors associated to the heterogeneous charging behavior. We found socio-demographics, vehicle characteristics, commute behavior, and workplace charging availability and limits as significant factors but workplace charging availability was the most important factors.
