Electrified Road Trips, Charging Infrastructure, and Equity

This presentation discusses the following key research questions: Where do we need on-route (or waypoint) and destination chargers, and how many? What is the impact of seasonal variations in both general road trips (e.g., Thanksgiving) and those related to recreational destinations (e.g., national parks)? Do we have appropriate electric grid ready along the routes? What equity implications would be worth considering?

Electrifying Road Trips to and from National Parks in the Western United States

We evaluate charging infrastructure requirement for electrified long-distance travels to/from national parks in the Western U.S. We conduct a high-resolution spatial and temporal analysis of road trips in the region, accounting for detailed travel volume and pattern, the type of electric vehicles, heterogeneous energy consumption rates depending on driving conditions, charging technology (e.g., power and speed), and charging behavior. The scope includes on-route (or way-point) charging as well as destination charging (in national parks). We estimate the locations and sizes of required charging stations in the entire Western U.S. to enable electrified road trips to/from national parks. We also examine environmental justice and energy equity aspects of projected charging infrastructure (for national parks) in the context of the overall vehicle electrification and charging infrastructure build-out.
