Energetics: Electric Vehicle Widescale Analysis for Tomorrow’s Transportation Solutions (EV WATTS)
Overview
As society increasingly prioritizes sustainable transportation, understanding the dynamics of electric vehicle (EV) adoption is paramount. EV WATTS addresses a growing need for practical information about vehicle electrification. The EV WATTS project team collected real-world use data from plug-in electric vehicles (PEVs) and charging stations (also known as EVSE – electric vehicle supply equipment). Researchers then validated, analyzed, and summarized the data, which is being used to inform future research, development, and deployment.

Driving Electrification Through the Power of Data
From 2019-2023, Energetics worked with Clean Cities Coalitions, fleets, state/local governments, vehicle manufacturers, utilities, charging station providers, and EV drivers to develop a national data resource on end-user driving and vehicle charging patterns, vehicle performance, and charging infrastructure activity. The data collection effort was comprehensive, covering:
- All-electric and plug-in hybrid electric vehicles telematics data
- A variety of vehicle types: cars, trucks, buses, etc.
- Multiple geographic areas and climates
- AC Level 2 and DC fast charging infrastructure
- Various EVSE sites: corridors, workplace, multi-unit dwellings, curbside, fleet depots, transit centers, ports, airports, etc.
“EV WATTS will facilitate unbiased analyses, drawing on diverse data that provides robust results from a broad stakeholder group. Having access to a uniform, comprehensive, and anonymized dataset from recent PEV and EVSE deployments across the U.S. will help Argonne National Laboratory understand charging behavior by vehicle class and trip purpose. It will also shed light on the correlation between EVSE availability and PEV adoption, laying the foundation for better future placements of infrastructure.”

Databases
The anonymized EV WATTS databases are publicly available through the U.S. Department of Energy Livewire Data Platform: https://livewire.energy.gov/ds/evwatts/evwatts.public. A free account can be used to download the database. All sensitive attributes have been removed from this publicly available dataset, and data partner agreements do not allow distribution of any additional data fields.
Data Dashboards
The two interactive EV WATTS dashboards (one for vehicles and one for charging stations) display statistics and findings from electric vehicle and charging station data across the United States: summary data, energy demand, use patterns, charging details, and more.
Technical Analysis (White Papers)
Energetics staff have published a series of white papers that leverage the EV WATTS data to explore important topics affecting individuals, municipalities, commercial fleets, and government agencies considering EV adoption or by those developing and implementing transportation electrification plans.
- Public Charging Station Peak Demand
- Electric Vehicle Charging Station Reliability
- Survey of EV Fleet Managers and EV Drivers
- Multi-Unit Dwelling Station Utilization
- Optimizing Battery Size for Fleet Battery Electric Vehicles
Data Reports
These national and regional reports summarize data from the EV WATTS database to show statistics and trends related to electric vehicle and charging station use. These are static versions of similar information shown on the interactive online dashboards.
