Plug-in Hybrid Electric Vehicles
DOE's Advanced Vehicle Testing Activity (AVTA), Idaho National Laboratory (INL), and testing partner Electric Transportation Engineering Corporation initiated Plug-in Hybrid Electric Vehicle (PHEV) testing activities during the second half of 2006. PHEVs are similar to hybrid electric vehicles with a few exceptions - PHEVs have much larger battery packs, allowing for increased all-electric and/or electric-assist range, and PHEVs must be connected to the electric grid to fully recharge the onboard battery packs. The AVTA's PHEV activities include:
- Development of PHEV Integrated Test Plan and Evaluation Program, which is used to conduct accelerated onroad and baseline performance (dynamometer and test track) testing.
- Testing is being conducted on nine PHEV models, with most of the PHEVs from conversion companies. The conversion companies and the base models include: the Hymotion Prius, Hymotion Escape, EnergyCS Prius, Renault Kangoo, HybridsPlus Escape, HybridsPlus Prius, Electrovaya Escape, Green Car Company Prius, and E85 capable Ford Escape.
- Onroad data collection has started for more than 50 PHVs already deployed with onboard data loggers being used to capture real-world fleet operations data, including vehicle operations and charging profiles. All of the testing results will be posted on these AVTA Web pages.
