SHOVEL, AND METHOD FOR CONTROLLING SHOVEL

摘要

A shovel includes a lower traveling body (1); an upper rotating body (3) provided on the lower traveling body; an electrical energy storage device (120) provided on the upper rotating body; a converter (100) connected to the electrical energy storage device; and a controller (30) that controls the converter. The controller (30) applies a current to the electrical energy storage device and the converter at the time of starting up the shovel, detects the status value after having applied the current, and controls the converter (100) based on a comparison result between the detected status value and a predetermined value to restrict an output of the electrical energy storage device.
