Patent number: 8286740Abstract: In a hybrid excavator, a generator motor and a hydraulic pump are driven by using an engine as a power source. A battery is charged with power generated by the generator motor. A rotation motor is driven by the generator motor and the battery. The voltage of a DC bus is detected by a voltage sensor, and whether the battery is unusable is determined by a breakdown detector. When the battery becomes unusable, emergency evacuation control is performed so that the power consumption of the rotation motor will be suppressed to be less than or equal to the power generation of the generator motor while maintaining the DC bus voltage greater than or equal to the normal operation voltage of the system.Type: GrantFiled: October 19, 2009Date of Patent: October 16, 2012Assignee: Kobelco Construction Machinery Co., Ltd.Inventors: Masayuki Kagoshima, Masayuki Komiyama, Keisuke Shimomura
