A large-scale study of PHEV charging

Addressing challenges related to transportation electrification and grid integration of electric and plug-in hybrid electric vehicles (PHEV), this paper presents results from a large-scale study of real-world PHEV driving and charging patterns. The dataset is based on over 100 PHEVs deployed in various scenarios across the U.S., including more than 39,500 driving trips, over 700,000 km driving distance, and over 7,400 charging events. Data analysis results indicate suboptimal utilization of PHEVs due to insufficient charging. Implications of PHEV proliferation on the power grid both in terms of power demand and the need for charging infrastructure are examined, highlighting the importance of user-vehicle-grid interactions.
