SHOVEL AND METHOD OF CONTROLLING SHOVEL
A shovel includes an electrical power storage device that may be made of a plurality of electrical power storage cells for charging electricity generated by a generator; and an electrical power storage administration part that includes equalizing circuits each of which may be connected to corresponding one of the plurality of electrical power storage cells, an equalizing circuit defect determination part which determines whether a defect exists in the equalizing circuit, and a shutoff part which shuts off a connection between the equalizing circuit in which the defect may be determined to exist and the electrical power storage cell connected to the equalizing circuit.
