Abstract
A battery protecting apparatus includes a battery manager and a wake-up switch. The battery manager manages charge and discharge states of a battery pack and wakes up when external power is received. The wake-up switch supplies the external power to the battery manager when an internal temperature of the battery pack is equal to or greater than a predetermined reference temperature. The battery manager performs an emergency protection operation based on detection of the battery pack in a predetermined dangerous state at a time when the ignition switch is turned off and the wake-up switch is turned on.
