INL is the lead laboratory for DOE’s Advanced Vehicle Testing Activity. INL’s conduct of the Advanced Vehicle Testing Activity resulted in a significant base of knowledge and experience in the area of testing light-duty plug-in electric vehicles and electric charging infrastructure that reduce transportation-related petroleum consumption. Because of this experience, INL was tasked by DOE to develop agreements with companies that were recipients of American Recovery and Reinvestment Act of 2009 Transportation Electrification grants that allowed INL to collect raw data from light-duty vehicles and charging infrastructure developed and deployed as a result of these grants. INL developed non-disclosure agreements with several companies and their partners, which resulted in INL being able to receive raw data via server-to- server connections from the partner companies. These raw data allowed INL to independently conduct data quality checks, perform analyses, and report publicly to DOE, partners, and stakeholders how drivers used both the new advanced plug-in electric vehicle (PEVs) technologies and the deployed charging infrastructure. The ultimate goal was not deployment of vehicles and charging infrastructure, but rather creation of real-world laboratories of vehicles, charging infrastructure, and drivers that would aid in the design of future electric drive vehicle transportation systems. The five projects and the goal of each project that INL collected data from were as follows: 1. ChargePoint America – PEV Charging Infrastructure Demonstration 2. Chrysler Ram PEV Pickup – PEV Demonstration 3. General Motors Chevrolet Volt – PEV Demonstration 4. The EV Project – PEV and PEV Charging Infrastructure Demonstration 5. South Coast Air Quality Management District/Electric Power Research Institute/Via Motors – PEV Demonstration. This document serves to benchmark the performance science involved in execution, analysis, and reporting for the five projects and share lessons learned based on drivers’ use of vehicles and recharging decisions made by the drivers. Results are reported describing the use of more than 25,000 vehicles and charging units across the United States. iii CONTENT ABSTRACT ................................................................................................................................................. iii ACRONYMS ........................................................................................................................................ xxxvii 1.
