  • Publication number: 20140091579
    Abstract: 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.

  • Publication number: 20140067176
    Abstract: 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.

  • Patent number: 7659878
    Abstract: A display control device has: a shift register generating n shift pulses in series; a data hold block configured to hold n gradation data; and a DA converter for converting the n gradation data into corresponding gradation voltages. The data hold block includes: n first latch circuits configured to respectively latch the n gradation data in series in synchronization with the n shift pulses; and n second latch circuits provided between the DA converter and the n first latch circuits. An electrical connection between the first latch circuits and the second latch circuits is cut off while the first latch circuits receive the n gradation data. After the first latch circuits finish latching all the gradation data, the n gradation data are simultaneously supplied to the DA converter from the first latch circuits through the second latch circuits.

  • Publication number: 20080213674
    Abstract: The present invention provides a secondary battery using a liquid electrolyte excellent in storage characteristics. The secondary battery includes a cathode, an anode, and a liquid electrolyte, where the cathode and the anode contain at least one mutual active material. This symmetrical electrode configuration, that the at least one active material for the cathode and the anode is mutual, enables equalization of an electrode electric potential difference before charge or after discharge; and thus electrolyte degradation is efficiently restrained to improve storage characteristics.
