<p>Disclosed are an apparatus and a method for protecting a battery pack. The apparatus includes: a sensor for detecting external physical impact so as to output a voltage signal; a first protection circuit for receiving the voltage signal output from the sensor; a gauging IC for determining whether the voltage received from the first protection circuit is larger than a predetermined value, so as to output the voltage signal to either the first protection circuit or a second protection circuit; the second protection circuit for receiving the voltage signal from the gauging IC; and an alarm circuit connected to the first and second protection circuits so as to receive the voltage signal from the first and second protection circuits and raise an alarm signal.</p> |
