Patent number: 8880265Abstract: Disclosed is a hybrid construction machine including: an engine, a generator-motor, a hydraulic pump, an electric storage device, a power control device which controls electric power between the generator-motor and the electric storage device, a temperature detector which determines a temperature of the electric storage device, an unload valve provided between a discharge port of the hydraulic pump and a tank, an unload-valve control device, and a relief valve. The power control device controls an electric power to be supplied from the electric storage device to the generator-motor, under abnormal circumstances where the temperature of the electric storage device is low, to a power obtained by adding an additional discharge power to a power to be supplied under normal circumstances. The unload-valve control device closes the unload valve, under abnormal circumstances. The relief valve controls the discharge pressure of the hydraulic pump to the set pressure, under abnormal circumstances.Type: GrantFiled: July 31, 2013Date of Patent: November 4, 2014Assignee: Kobelco Construction Machinery Co., Ltd.Inventors: Naoki Goto, Yoichiro Yamazaki, Masayuki Komiyama, Takayuki Doi

Publication number: 20140091579Abstract: A charge and discharge control unit (41) sets an upper-limit charge and discharge electric power as an upper limit of electric power during charging and discharging of a electric storage device (11) based on temperature of the electric storage device (11) measured by a temperature measuring unit (21) and a state of charge of the electric storage device (11) specified by a charge state specifying unit (23). In the case where the operation state determined by an operation state determining unit (35) is a low-limit operation state, the charge and discharge control unit (41) sets the upper-limit charge and discharge electric power to be larger than that in the case where the operation state determined by the operation state determining unit (35) is a high-limit operation state.Type: ApplicationFiled: September 17, 2013Publication date: April 3, 2014Applicants: KOBELCO CONSTRUCTION MACHINERY CO., LTD., Kabushiki Kaisha Kobe Seiko Sho (Kobe Steel, Ltd.)Inventors: Yoshiaki Kitamura, Takayuki Doi, Naoki Goto
