EVALUATE: Electric Vehicle Assessment and Leveraging of Unified models toward AbatemenT of Emissions, Phase I

Research Product Type

Research Report

This research explores electric vehicle (EV) and grid interactions with a focus on CO2 emissions through integrating models and data that characterize: vehicle energy consumption, travel demands, vehicle charging, and temporal emission profiles associated with electric power generation dispatch. This convergence research helps quantify the relative emissions of light duty vehicle use and charging during various times of day to enable comparison of EV modes against one another and against conventional vehicle baselines.

EVALUATE: Electric Vehicle Assessment and Leveraging of Unified models toward AbatemenT of Emissions, Phase II

Research Product Type

Research Report

The EVALUATE project develops methodology for forecasting emissions outputs of a class of vehicles and use cases. Phase II focuses on targeted case studies that extend prior work from light duty vehicles operated by individuals to service-oriented vehicles operated by small and medium businesses.

Expectations versus Experience: The Case of Plug-in Electric Vehicles and Their Policy Implications

Principal Investigator Seshadri Srinivasa Raghavan, Ph.D.
University of California, Davis

This dissertation presents a unified framework for understanding plug-in electric vehicle (PEV) usage, with special focus on household factors, user preferences, and PEV technologies. The researcher also looks at energy, emissions, and infrastructure-related factors.
