Hybrid construction machine and auxiliary control device used therein
Disclosed is a hybrid construction machine that includes a control device and an auxiliary control device. The control device switches between a hydraulic/electric complex swing mode in which both the electric motor and the hydraulic motor are driven to drive the swing structure by using the sum of the torque of the electric motor and the torque of the hydraulic motor; and a hydraulic-only swing mode in which only the hydraulic motor is driven to drive the swing structure by using only the torque of the hydraulic motor. The auxiliary control device includes a monitoring controller that is connected to the control device and to the electric motor to monitor the temperature or electrical leakage in the electric motor as a substitute controller for the power control unit or the electrical storage device when the power control unit or the electrical storage device is removed due to a fault.
