Abstract
A battery management system (BMS) may include a battery, a relay configured to electrically connect and disconnect the battery for supplying a voltage (an electric power) to an electric load to and from the electric load, the electric load configured to receive the voltage (the electric power) from the battery, to compare the received voltage (the electric power) with a reference value and to output a wakeup signal according to the compared result, when the relay is electrically connected, and a controller configured to wake up by the wakeup signal, to monitor a state of the battery and to control a state of the relay. It is possible to prevent overdischarge and overcharge of the battery by monitoring the battery through the electric load in a state in which a vehicle is turned off and switching the BSM to a wakeup state only if necessary.
