Congress seeks to reduce petroleum consumption by encouraging the use of electric vehicles and has legislated an Electric and Hybrid Vehicle Demonstration project. In carrying out this mandate, DOE developed a data plan to assess the Demonstration project. The Data Aquisition and Reduction Module (DARM) System was developed by LLNL for use on demonstration electric vehicles to determine reliably and inexpensively quantitative data on their performance. The DARM System consists of an instrumentation unit which is installed in selected demonstration vehicles, a tape reader, and data reduction programs. Once the on-board DARM unit is installed, the vehicle operator needs only to insert and remove cassette tapes at intervals of up to three months. The tapes can be reduced with the specialized reduction programs, entered into a data base, and the data subjected to analysis at a Data Reduction Center. DARM povides data on energy consumption (into and out of the battery), distance and time travelled, and number of stops experiences. A profile of energy consumption and time spent as a function of speed and acceleration allows deduction of driver satisfaction and provides direction to designers for improving electric vehicle performance.
