A battery charging and discharging apparatus includes power converters connected in series and configured to convert respective output voltages of batteries corresponding to the power converters. Each of the power converters may include direct current to direct current (DC/DC) converters connected in parallel. The apparatus may further include a controller configured to control magnitudes of respective output voltages of the power converters based on respective states of the batteries.

Apparatus for charging and discharging battery

An apparatus and method for managing a battery are disclosed. The apparatus may include a state verifier configured to verify respective states of charge (SoCs) of batteries to be balanced by the apparatus, and a controller configured to control power converters configured to convert respective amounts of power of the batteries to allow a greater amount of power to be output from a battery having a greater SoC among the batteries.
