EVALUATION OF RANGE ESTIMATES FOR TOYOTA FCHV-ADV UNDER OPEN ROAD DRIVING CONDITIONS

Description: The objective of this evaluation was to independently and objectively verify driving ranges of >400 miles announced by Toyota for its new advanced Fuel Cell Hybrid Vehicle (FCHV-adv) utilizing 70 MPa compressed hydrogen. To accomplish this, participants from both Savannah River National Laboratory (SRNL) and the National Renewable Energy Laboratory (NREL) witnessed and participated in a 2-vehicle evaluation with Toyota Motor Engineering & Manufacturing North America, Inc. (TEMA) over a typical open road route for over 11 hours in one day with all relevant data recorded. SRNL and TEMA first entered into discussions of verifying the range of the advanced Toyota Fuel Cell Hybrid Vehicle (FCHV-adv) in August 2008 resulting from reported 400+ mile range by Toyota. After extended negotiations, a CRADA agreement, SRNS CRADA No. CR-04-003, was signed on May 6, 2009. Subsequently, on June 30, 2009 SRNL and NREL participated in an all-day evaluation of the FCHV-adv with TEMA to determine the real-world driving range of this vehicle through on-road driving on an extended round-trip drive between Torrance and San Diego, California. SRNL and NREL observed the vehicles being refueled at Toyota's headquarters the day before the evaluation in Torrance, CA on June 29. At 8:00 AM on June 30, the vehicles departed Torrance north toward downtown Los Angeles, then west to the Pacific Coast Highway, and down to San Diego. After lunch the vehicles retraced their route back to Torrance. The traffic encountered was much heavier than anticipated, causing the vehicles to not return to Torrance until 9 PM. Each vehicle was driven by the same Toyota driver all day, with one SRNL/NREL observer in each vehicle the entire route. Data was logged by Toyota and analyzed by NREL. The maximum range of the FCHV-adv vehicles was calculated to be 431 miles under these driving conditions. This ...

Controlled Hydrogen Fleet and Infrastructure Demonstration and Validation Project: Fall 2006 Progress Update

Description: The U.S. Department of Energy (DOE) initiated the Controlled Hydrogen Fleet and Infrastructure Demonstration and Validation Project through a competitive solicitation process in 2003. The purpose of this project is to conduct an integrated field validation that simultaneously examines the performance of fuel cell vehicles and the supporting hydrogen infrastructure. Four industry teams have signed cooperative agreements with DOE and are supporting plans for more than 130 fuel cell vehicles and 20 hydrogen refueling stations over the 5-year project duration. This paper provides a status update covering the progress accomplished by the demonstration and validation project over the last six months; the first composite data products from the project were published in March 2006. The composite data products aggregate individual performance into a range that protects the intellectual property of the companies involved, while publicizing the progress the hydrogen and fuel cell industry is making as a whole relative to the program objectives and timeline. Updates to previously published composite data products, such as on-road fuel economy and vehicle/infrastructure safety, will be presented along with new composite data products, such as fuel cell stack efficiency and refueling behavior.
