Abstract
A vacuum cleaner includes: a cleaner main body including a suction motor for generating a suction force; a suction unit that is in communication with the cleaner main body and sucks air and dust; a battery that supplies power to the suction motor; a battery management system (BMS) that detects a status of the battery; and a controller that controls an operation of the suction motor, wherein, if a voltage of the battery detected by the BMS reaches a reference voltage, the controller stops the suction motor, and the reference voltage is changeable.
Claims20
A vacuum cleaner comprising:
- a cleaner main body having a motor that generates a suction force;
- a suction unit that is in communication with the cleaner main body and sucks air and dust based on the suction force;
- a battery that supplies power to the motor;
- a battery management system (BMS) that detects a status of the battery;
- and
- a controller that controls an operation of the motor,
- wherein the suction motor is stopped when a voltage of the battery detected by the BMS reaches a reference voltage, and the reference voltage is changed based on a condition of the battery.
A vacuum cleaner comprising:
- a cleaner main body having a motor to generate a suction force;
- a suction unit in communication with the cleaner main body and sucks air and dust based on the suction force;
- a battery that supplies power to the motor and includes a plurality of battery cells;
- a battery management system (BMS) that detects a status of the battery;
- and
- a controller that controls an operation of the motor,
- wherein the motor is stopped when a voltage of all of the plurality of battery cells detected by the BMS reaches a reference voltage, and
- the reference voltage is reduced based on increased usage of the battery.
