Performance benefits of a portable hybrid micro-gas-turbine POWER SYSTEM FOR AUTOMOTIVE APPLICATIONS

摘要

The lower fuel burn and pollutant emissions of hybrid electric vehicles give a strong motivation and encourage further investigations in this field. The knowhow on hybrid vehicle technology is maturing and the reliability of such power schemes is being tested in the mass production. The current research effort is to investigate novel configurations, which could achieve further performance benefits.This paper presents, an assessment of a novel hybrid configuration comprising a micro gas turbine, a battery bank and a traction motor, focusing on its potential contribution to the reduction of fuel burn and emissions. The power required for the propulsion of the vehicle is provided by the electric motor. The electric power is stored by the batteries, which are charged by a periodic function of the micro gas turbine. The micro gas turbine starts up when the battery depth of discharge exceeds 80% and its function continues until the batteries are full.
