摘要： A hybrid system working machine is, during a normal working time, operated by a normal operation mode that the output of a power generator and the accumulated power of a capacitor are used while the engine is operated over a high-efficiency range at a low output. Switching of a selector switch to a high-speed running mode position and running operation enable long-distance and high-speed running of an increase in engine output by a high-output operation mode.

摘要： In a hybrid excavator, a generator motor (2) and a hydraulic pump (3) are driven by using an engine (1) as a power source. A battery (11) is charged with power generated by the generator motor (2). A rotation motor (8) is driven by the generator motor (2) and the battery (11). The voltage of a DC bus (9a,9b) is detected by a voltage sensor (14), and whether the battery (11) is unusable is determined by a breakdown detector (15). When the battery (11) becomes unusable, emergency evacuation control is performed so that the power consumption of the rotation motor (8) will be suppressed to be less than or equal to the power generation of the generator motor (2) while maintaining the DC bus (9a,9b) voltage greater than or equal to the normal operation voltage of the system.
