Zusammenfassung:	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.
