  • Patent number: 10766480
    Abstract: A hybrid construction machine includes: a motor generator system connected to an internal combustion engine and performing a motor generator operation; an electric power accumulation system connected to the motor generator system; a load drive system connected to the electric power accumulation system and being driven electrically; an abnormality detection part equipped to the motor generator system, the electric power accumulation system and the load drive system; and a main control part determining whether an abnormality has occurred based on a detection value of the abnormality detection part. When the abnormality determination part determines that an abnormality has occurred, the main control part stops a drive of a drive system in which the abnormality is detected in the load drive system.

  • Patent number: 9000716
    Abstract: A hybrid working machine includes a first electric motor performing a power running operation of being driven with supplied electric power and a regenerative operation of generating electric power; a first electric circuit controlling the output of the first electric motor; a battery supplying the first electric motor with the electric power and storing the regenerated electric power from the first electric motor; a charge and discharge circuit controlling the charging current and the discharge current of the battery; and a controller controlling the charge and discharge of the battery for driving the machine. The controller calculates a level representing a proportion by which the output of the battery is limited with respect to each of multiple conditions related to the output of the battery. The controller limits the charging current and the discharge current of the battery based on the calculated levels.

  • Patent number: 8798875
    Abstract: A working machine includes: a first electric motor used for work; a second electric motor used for applications other than work; a first inverter circuit connected to the first electric motor; a second inverter circuit connected to the second electric motor; a battery connected to the first and second inverter circuits; and a control unit that drives the first and second inverter circuits. The control unit has a discharge mode to discharge electric power stored in the battery, and discharges the battery by stopping the first inverter circuit while driving the second inverter circuit in order to make the second electric motor perform electric operation in the discharge mode. Accordingly, since the state of charge is reduced, the life of a capacitor can be increased.
