1. A battery management device for managing a battery pack including a plurality of battery modules, comprising:
a plurality of slave controllers including:
at least one sensing port connected to at least one battery cell provided to the battery modules through a sensing line, and configured to sense a voltage of each connected battery cell; and
at least one ID allocation port configured to receive the voltage from the sensing line when being connected to the sensing line,
the plurality of slave controllers being configured to be connected to at least one corresponding battery module among the battery modules; and
a master controller connected to the plurality of slave controllers, respectively, configured to:
receive voltage information about the voltage applied to the ID allocation port from the slave controller; and
allocate a regular ID to each of the plurality of slave controllers based on the received voltage information.
