AVTA ParticipantsTh Ad d V hi l T ti A ti it (AVTA) i th U S• The Advanced Vehicle Testing Activity (AVTA) is the U.S. Department of Energy, Vehicle Technologies Program’s (VTP) singular field, tract, and laboratory based source of t ti li ht d t h l hi l t d b ttesting light-duty whole vehicle systems and subsystems– Idaho National Laboratory manages the AVTA for VTP– ECOtality provides testing support via a competitively y p g pp p y
bid NETL (National Energy Testing Laboratory) contract
• For the EV Project, ECOtality is the project lead and INL j , y p jprovides data collection, analysis and dissemination support
• Test partners include electric utilities, Federal, state andTest partners include electric utilities, Federal, state and local government agencies, private companies, and individual vehicle owners

AVTA GoalsTh AVTA l• The AVTA goals– Petroleum reduction and energy security– Benchmark technologies that are developed via DOEBenchmark technologies that are developed via DOE
research investments• Provide benchmark data to DOE, National Laboratories
(ANL, NREL, ORNL, PNNL), Federal Agencies (DOD, DOI,(ANL, NREL, ORNL, PNNL), Federal Agencies (DOD, DOI, DOT, EPA, USPS), technology modelers, R&D programs, vehicle manufacturers (via USCAR’s VSATT, EESTT, GITT), and target and goal setters ), g g
• Assist fleet managers, via Clean Cities, FEMP and industry gatherings, in making informed vehicle and infrastructure deployment and operating decisionsinfrastructure deployment and operating decisions

off-peak with charge-starts at midnight per TOU ratesoff peak with charge starts at midnight per TOU rates indicates consumers are price sensitive
• Revenue models for public charging are currently being introduced – long term impacts?introduced long term impacts?
• Only about 60% of EV Project data collected to date• DCFC charge events have significant demand impacts
