CHARACTERIZATION OF ELECTRIC VEHICLE VELOCITY AND POWER PROFILES USING ROAD TEST DATA. IN: RECENT ADVANCES IN ELECTRIC VEHICLE TECHNOLOGY. FUTURE TRANSPORTATION TECHNOLOGY CONFERENCE AND EXPOSITION, VANCOUVER, BC, CANADA, AUGUST 7-10, 1989

The use of electric vehicle road test data to characterize various missions in terms of velocity time-histories and battery power profiles is discussed. The data utilized were taken on the Griffon Van at Detroit Edison using the VDAS on-board data system, which stores the data in several frequency-of-occurance matrices. Time based data are not available from VDAS. Construction of velocity-time cycles from the mechanical power-velocity matrices has proven to be difficult. A new VDAS, which stores the vehicle/battery data in time-based files, has been designed and built at the INEL. Bench testing of the unit is near completion and in-vehicle testing should begin in June 1989. The new VDAS utilizes the same sensors as in the original VDAS and will yield essentially the same data variables. The frequency-of-occurrence matrices can be constructed from the time-based data using a Vax 2000 workstation and commercially available softwear. Work is continuing on developing vehicle and battery test cycles from VDAS field data for the various missions.
