    摘要： Provided is an electric construction machine capable of avoiding a situation where charging is difficult to achieve due to the exhaustion of a battery device. An electrically-operated hydraulic excavator includes an electric motor 31, a hydraulic pump 33 that is driven by the electric motor 31, hydraulic actuators 13A, 13B, 19 to 21 that are driven by hydraulic fluid discharged from the hydraulic pump 33, and a battery device 7 that serves as an electrical power source for the electric motor 31. The battery device 7 includes battery systems 56A, 56B that each have a plurality of batteries 55. A selector switch 28 makes it possible to select either one of the battery systems 56A, 56B. An arithmetic control section 53 of an inverter device 32 controls connection change switches 58A, 58B through battery controllers 54A, 54B to change the connections of the battery systems 56A, 56B so that electrical power is supplied to the electric motor 31 from either the battery system 56A or the battery system 56B, whichever is selected by the selector switch 28.

    摘要： A hybrid powertrain for powering a vehicle includes a micro turbine assembly with multi-fuel capabilities and a turbine drive shaft extending therefrom. The turbine drive shaft has a turbine engaged position where a turbine rotational output of the micro turbine assembly is transferred by the turbine drive shaft to wheels of the vehicle, and a turbine unengaged position where the turbine rotational output is independent from the wheels. A generator is selectively connected to the micro turbine assembly in parallel with a portion of the turbine drive shaft. A power storage device is chargeable by the generator and can drive an electric motor. A motor drive shaft has a motor engaged position where a motor rotational output of the electric motor is transferred by the motor drive shaft to the wheels, and a motor unengaged position where the motor rotational output is independent from the wheels.
