Disclosed is a battery management apparatus capable of effectively reducing the current consumption of a component for waking up a microcontroller unit. The battery management apparatus includes a wake-up unit, a first power supply path, a first regulator, a first switching element, a feedback module, and a microcontroller unit configured to convert a sleep mode to a wake-up mode by receiving a wake-up signal from the wake-up unit and connected to the feedback module to turn off the first switching element.
