The Electric Vehicle (EV) Site Operator Program, is currently composed of thirteen Site Operators. In addition to operating electric vehicles for demonstration of the technology, the Site Operators also perform operational field testing. Data collected by the programs are input to the Site Operator Database at each site and transmitted, periodically, to the database at the INEL. As the program has expanded, some Site Operators have begun operating vehicles at sites remote from their offices. With the advent of these expanded test programs, it is necessary to consider in-vehicle, automated data acquisition systems. Three of these in-vehicle, data acquisition systems have been designed and constructed: The Mobile Data Acquisition System (MDAS) was designed and constructed by Sigma TecSystems, Inc. located in Tampa, Florida. The Versatile Data Acquisition System (VDAS) was designed and constructed at the INEL under the guidance of the Electric and Hybrid Vehicle (EHV) Program. The AUTOLOGGER Vehicle User Survey System produced by Instrumental Solutions of Ottawa, ON. Because the USF MDAS is a new system proposed for use by the Site Operator Program, the purpose of this report is to provide a preliminary evaluation of the MDAS by comparing the system to the proven VDAS. Data used to perform the comparison was acquired by a review of the MDAS literature provided by the USF, and by a demonstration of the MDAS and its performance, provided by the USF to INEL personnel. A brief discussion of the AUTOLOGGER is also included, for comparison, because it is being used by Southern California Edison (SCE), one of the Site Operator Program participants who recommends the unit as a good system.
