Abstract:
1. A method for controlling a portable range extender capable of supplying electrical energy to a vehicle, the range extender including a dynamoelectric machine mechanically coupled to an internal combustion engine by a shaft and electrically coupled to an electric power source wherein said dynamoelectric machine drives the shaft to start the internal combustion of the engine, comprising: applying electrical energization from a power source to the dynamoelectric machine for operation as a motor to drive the shaft to start the engine in rotation in response to an initiation input; sensing the rotational speed of the shaft; sensing the temperature of the engine; in response to a sensed rotational speed that meets a first predetermined speed threshold and a sensed engine temperature that meets a predetermined temperature threshold, supplying fuel to the engine and activating an ignition of the engine for operation as a prime mover; and after a period of engine prime mover operation, operating the dynamoelectric machine as a generator to provide an electrical current output.
