The Vehicle Technologies Office's Advanced Vehicle Testing Activity carries out testing on a wide range of advanced vehicles and technologies on dynamometers, closed test tracks, and on-the-road.  These results provide benchmark data that researchers can use to develop technology models and guide future research and development. The following report describes best practices for responding to emergency incidents involving plug-in electric vehicle batteries, based on the AVTA's testing of PEV batteries. This research was conducted by Idaho National Laboratory.
