Patent ID: 8552575

Claim:
A hybrid electric power system having a hybrid gas turbine (HGT) electrical power plant as one electric power source and a battery pack as another electric power source in combination with a motor drive system as a prime mover for vehicular propulsion comprised of: a) the hybrid gas turbine (HGT) electrical power plant having, an engine body, at least two spools within the engine body where a first spool is an electric power producer having an integrated alternator rotor with retained permanent magnets, a compressor rotor driven by a turbine rotor via a rotatable shaft; a second spool having fluid communication with the first spool, has an integrated compressor rotor driven by a turbine rotor via a rotatable shaft, whereas the compressor rotor of the second spool has an air inlet supply supplying compressed air to a compressor rotor inlet of the compressor rotor of the first spool, a turbine rotor exit of the turbine rotor of the first spool is in communication with a turbine rotor inlet of the turbine rotor of the second spool; an alternator stator within the engine body having stacked iron laminates, magnetic wound wire and output power leads, the alternator is co-axially located about and in close proximity to said alternator rotor; and a combustor within said engine body, has communication with a compressor exit and a turbine rotor inlet of the turbine rotor of the first spool and also within at least one fuel/air nozzle and an igniter; b) an electro-mechanical fuel valve for controlling the fuel flow to the combustor, having a fuel inlet supply line from an external fuel source and a fuel exit/discharge in communication with said fuel/air nozzle within the HGT; c) a power electronics package is in communication with said HGT, and said alternator stator output power leads for converting engine output high voltage-high frequency power to useful electrical power and frequency; d) an electronic engine control unit (EECU) having electrical communication with said electro-mechanical fuel valve; e) a throttle box having electrical communication with the said EECU; f) a voltage regulator is in communication with the power electronics package and said EECU; g) the battery pack is in series with the said power electronics package and has communication with said EECU; h) an electrical power source control (EPSC) having communication with said battery pack; and i) at least one electric motor having an output power shaft and in communication with said EPSC and said EECU, wherein said EPSC is used to select said electric power source to drive said at least one electric motor.
