Abstract
A charger and a control method are disclosed. A charger according to an embodiment of the present disclosure includes a transceiver configured to obtain, from a battery of a cleaner, temperature information of the battery, and a processor configured to apply power to the battery based on the temperature information transmitted from the transceiver, wherein the processor applies a pulse wave of a first period to the battery when the temperature of the battery is measured within a predetermined first section. Accordingly, even if the temperature of the battery is outside the charge allowance range due to the discharge of the battery built in the cleaner, the battery can be charged more quickly, thereby reducing the total time required for charging the battery.
