This report describes the findings from the Advanced Plug-in Electric Vehicle Travel and Charging Behavior Project. The purpose of this project is to understand the emissions potential of plug-in electric vehicles (PEVs) under real world conditions, highlight benefits and challenges, and present needs for improving and regulating future electric vehicles. The project and this report include results from a study on cold starts and charging behavior that was added to the initial scope of work. The project provides a platform to monitor how new PEVs are being used on a day-to-day and month-to-month basis within the household travel context, by placing data monitoring devices (loggers) in all vehicles in participant households for a period of one year. The project provides a common basis to evaluate technologies side-by-side in a consistent way.

The project began with studying three models of plug-in vehicles: the Toyota Plug-in Prius (Model Years [MY] 2012–2016), the first-generation Chevrolet Volt (MY 2010–2015)--both plug-in hybrid electric vehicles (PHEVs)--and the first generation Nissan Leaf (MY 2010–2016) battery electric vehicle (BEV). As the project progressed, six additional and updated models have been added: the Ford C-Max Energi PHEV (MY 2014-2016), Ford Fusion Energi PHEV (MY 2014-2016), second generation Volt (MY 2016), second generation Leaf with 30kWh pack (MY 2014–2016), BMW i3 REx range-extended BEV (BEVx)(MY 2014-2016), and Tesla Model S with battery size of 60-80kwh. The BMW i3 REx had compatibility problems with the on-board data monitoring devices resulting in bad data and are not included in …
