1. An apparatus for protecting a battery pack, comprising:
a battery pack including a negative terminal, a plurality of positive terminals, and a plurality of battery cells, the negative and positive terminals being connected to a power conversion device, and the plurality of battery cells being configured to be charged by power supplied through the power conversion device;
a plurality of latch relays connecting the plurality of positive terminals and the plurality of battery cells so that connection of the positive terminals and the battery cells can be individually released;
a reverse connection releasing unit configured to determine whether the battery pack has been reversely connected to the power conversion device, and when it is determined that the battery pack has been reversely connected to the power conversion device, to generate a reverse connection detection signal, and to transmit a turn-off signal to the plurality of latch relays; and
a battery pack controller configured to transmit the turn-off signal to the plurality of latch relays when the reverse connection detection signal is applied from the reverse connection releasing unit.
