Abstract

A battery pack includes: a first switch connected between a first end of a battery and a first output terminal; a second switch including a first terminal and a second terminal which are connected to a second end of the battery, and a third terminal and a fourth terminal which are connected to a second output terminal, wherein the first terminal and the third terminal are electrically connected when the second switch is turned off, and the second terminal and the fourth terminal are electrically connected when the second switch is turned on; a pre-charge resistor connected between the third terminal of the second switch and the second output terminal; and a controller configured to control the second switch such that the second switch is turned on if a precharging period of time elapses after the first switch is turned on.
