Abstract:
A hybrid excavator includes a control unit that is arranged at an upper turning body and is configured to supply a drive signal to at least one of a motor generator control part and a charge/discharge control part. During a regeneration operation performed by a motor, the control unit sets an electrical energy storage target value for a second electrical energy storage device to a higher value than an electrical energy storage target value for a first electrical energy storage.
