Abstract
An apparatus for controlling a battery includes a capacitor for charging a voltage when the apparatus is on and discharging a voltage when the apparatus is off, a discharging circuit for discharging the voltage charged in the capacitor; a first switching unit for connecting or disconnecting the capacitor to/from a predetermined power source for the purpose of charging of the capacitor; a second switching unit for connecting or disconnecting the capacitor to/from the discharging unit; a voltage measuring unit for measuring a voltage charged in the capacitor; and a controller for calculating a power-off duration time according to the measured voltage. This apparatus may continuously calculate a power-off duration time of a battery pack.
