DECREASING ON-BOARD FUEL CONSUMPTION IN HEAT ENGINE/BATTERY ELECTRIC HYBRIDS BY BATTERY DEPLETION

Tests performed on three different configurations of hybrid vehicles establish that significant quantities of on-board petroleum fuel can be conserved by allowing the batteries to be discharged during the driving mission. The depleted batteries are then charged when the vehicle is not in use. Savings of as much as 50% of the on-board petroleum have been experienced with tests on the FDC. On SAE J227a, gasoline FE greater than 50 mpg was measured. Since all three hybrids were designed to reduce emissions the results reported herein of reducing fuel consumption by battery discharge must be recognized as indicative of trends, not measurements of absolute magnitudes of petroleum that can be saved, and electrical energy that must be used instead. Tests indicate that up to 50% of on-board petroleum can be saved.
