Most hybrid electric vehicle concepts use off-peak electricity from the utility grid to recharge their batteries at night. Recent developments in gas turbines and batteries could change this strategy for some vehicles. Gas turbine-driven generator sets equipped with catalytic combustors have emissions that are lower than those of the California standards for Ultra Low Emission Vehicles. With an on-board micro gas turbine generator set weighing 36 kg (80 lb) and producing 24 kW, the battery capacity, size and weight could be reduced by a factor of about four. The need for plugging in to recharge would be eliminated and the vehicle range would be limited only by the capacity of the fuel tank. The turbine would provide power for cruising while a bipolar lead-acid battery would provide additional power for acceleration, passing and hill climbing. The battery would also be used to recover energy that would otherwise be dissipated in braking. Bipolar lead-acid batteries have the high power, high turnaround efficiency and high discharge and recharge rates needed for this hybrid strategy. They also have the ability to handle the large number of cycles that will be encountered in this application. The hybrid vehicle concept offers lower emissions, lower energy consumption, lower initial cost and lower operating cost than conventional hybrids. At the same time, the range and performance match or exceed those of conventional gasoline and diesel-powered vehicles. This paper analyzes the characteristics of three vehicle concepts using this strategy: an automobile, a van and a bus.
