| Zusammenfassung: | An electric vacuum cleaner including: a secondary battery; an electric blower that generates negative pressure by consuming electricity stored in the rechargeable battery; and a control unit that controls driving of the electric blower, and changes discharge current of the rechargeable battery based on the difference between terminal voltage of the rechargeable battery while the electric blower is stopped and terminal voltage of the rechargeable battery after a predetermined time has elapsed since the electric blower has been started up. The electric vacuum cleaner can continue driving of an electric blower and increase operation time even in the state that the internal resistance of a rechargeable battery is increased. |
