The U.S. transportation system is moving toward electrification with plug-in electric vehicle (PEV) adoption and EV charging station infrastructure (EVSE) on the rise. This trend has created a need for up-to-date national data on these technologies as the demand for big data also rises. As fleet managers and decision makers look to utilize all available types of funding and resources on their journey to transportation electrification, the need for high quality electric vehicle (PEV) and electric vehicle charging (EVSE) data also becomes an important piece of the puzzle when addressing the environmental, performance, and financial sustainability for fleets.

 

What is EV WATTS?

EV WATTS is a Dept of Energy funded project led by Energetics collecting electric vehicle and charging station data to create a transportation electrification dataset that will inform future research, development, and deployment. With the rapid increase in vehicle electrification, there is a need for an up-to-date, publicly available national data to understand end user charging and driving patterns as well as vehicle and infrastructure performance to inform research planning. The project is working with partners (states, regional and local government agencies, vehicle manufacturers, utility companies, fleets, and others) to collect, analyze, anonymize, summarize, and publicly release real-world datasets from plug-in electric vehicle and charging stations. The results from this study will be used to inform decision making for multiple stakeholders: manufacturers, consumers, charging station hosts, and researchers.

 

How is the study collecting PEV and EVSE Data?

The project is collecting data from approximately 1,600 plug-in electric vehicle (PEV) and 10,000 electric vehicle charging ports nationwide representing diverse vehicle sizes (all-electric, plug-in hybrid electric vehicles), types (light, medium, heavy-duty), charging station types (Level 2, DC Fast Charging), settings, and operating conditions. The study is also providing project funded Geotab GO9 dataloggers to fleets and individual motorists to collect new trip-level PEV data. This data collection portion of the study was designed to better aggregate PEV trip-level data as part of the national dataset but also give fleets and individual EV owners the opportunity to pilot a telematics device and software program from leading telematics providers, Geotab and Sawatch Labs.

 

Once the data is collected and analyzed, as the project has been doing over the past year, the results (both data sets and analyses) is made publicly available on the EV WATTS website. Summary analyses have been updated quarterly since the start of 2021 and the comprehensive data sets will be made available at the end of the project in December 2022. Energetics is anonymizing all data sets and summary reports to protect sensitive information as DOE does not want any personally identifiable information. Clean Fuels Ohio has been working with several data partners including municipalities and universities in the state of Ohio to contribute PEV and EVSE data to the EV WATTS dataset. The results of these partnerships will not only provide further insight for each of the specific data partners, but also help move Ohio forward in its journey to expand transportation electrification efforts.

EV WATTS Data Dashboard and the Importance of EV & EV Charging Data Analysis

Earlier this year, Energetics publicly released the EV WATTS dashboard, an interactive interface that displays statistics and findings from electric vehicle and charging station data across the United States. The dashboard presents PEV and EVSE summary data, energy demand, use patterns, session details, and more from collected data to-date. Visit www.evwatts.org to view the dashboard.

EV WATTS is addressing a growing need for big electrification data but also practical information about vehicle electrification. Researchers from the Energetics team validate, analyze, and summarize the data, which can be used to inform future research, development, and deployment. Through telemetry software platforms from Sawatch Labs and Geotab, the level of detail in both the trip-level and charging data allows fleets to know how well their EV is performing. Fleets can also compare their vehicle’s performance to the EV WATTS national data set. All data in the comparison analysis section is scrubbed of any personally identifying information and anonymized to keep data confidential between partners. This section can give a fleet manager in Ohio an inside look at how an EV’s charging rate, for example, compares to a similar EV in the Southeast part of the United States. 

 

Clean Fuels Ohio and EV WATTS Continues to Seek EV Fleets
Clean Fuels Ohio has supported fleets across the state of Ohio with EV planning and purchasing for a number of vehicle applications—from light-duty municipal sedans, medium-duty paratransit passenger vans, and heavy-duty yard hosteler terminal trucks. While the EV WATTS study is looking to wrap up data partner engagements in early 2022, fleets with EVs are still eligible to sign-up and share existing data or receive free telematics and personalized fleet analyses. “We are grateful and excited for our partners that have already contributed data to this study that will represent Ohio’s progress in transportation electrification,” Andrew Conley, Chief Program Officer of Clean Fuels Ohio, said. “We look forward to working with other fleets and EV industry stakeholders to advance the use and understanding of telemetry and cost savings for Ohio fleets.”
