Abstract
Abstract A hybrid electric motor vehicle drive charged by a gas turbine which has an electric motor (20) driving a set of wheels (22) through a transmission (24). A number, preferably two, battery banks (28 and 30) supply power to the motor. A switchover control (30) selects one bank to operate the motor while leaving the other at rest. A sequence control (34) permits charging of individual batteries of the at rest battery bank with duration and sequence modulation from a gas turbine driven alternator (44), a motor driven alternator (52) and/or an AC/DO battery charger (54). The sequence controller senses time, or in other embodiments, voltage, amperage or distance to switchover the charging from one bank to the other. Hydrogen gas is preferred as a fuel source for the gas turbine to drive the alternator for onboard charging of the batteries.
