Abstract
A cordless vacuum cleaner includes a cleaner main body and a station. The cleaner main body includes a battery and a first processor controlling performing a cleaning function using power of the battery. The station includes a power conversion device to generate a voltage to charge the battery of the cleaner main body, a second charge terminal to charge the battery of the cleaner main body with the voltage generated by the power conversion device, a temperature sensor installed within a distance from the second charge terminal and to detect a temperature of the second charge terminal, a divider resistor to provide a voltage by dividing of an input voltage with the temperature sensor, and a second processor controlling performing an overheating prevention operation based on a voltage level of the voltage provided by the divider resistor and the temperature sensor being greater than a threshold voltage level.
