A CRITICAL REVIEW AND EVALUATION OF PUBLISHED ELECTRIC-VEHICLE PERFORMANCE DATA

E.V. published performance characteristics were successfully correlated with "Naturally-occurring" parameters that emerged from a vehicle mass and energy balance. Since the gravimetric-energy-content of batteries is less than 1/100 that of petroleum, the E.V. mass-fraction dedicated to energy-storage must be much greater than it is for petroleum-fueled vehicles. Thus, E.V's must be built to value range at the (necessary) expense of competing values (e.g., energy-utilization, "crashworthines", etc.). Data from 68 E.V.'s were plotted to show how: (i) increasing battery mass-fraction increases vehicle total-mass to payload-mass ratio; (ii) vehicle energy-utilization decreases with decreasing payload mass-fraction (in response to increasing battery mass-fraction) and; (iii) The design range reaches an upper limit as battery mass-fraction is increased. /SAE/
