The present invention relates to input/output control of an energy storage system and, more particularly, to an input/output control apparatus of an energy storage system, which receives input AC voltage and input frequency of a charger and output AC voltage and output frequency of an inverter from a battery management system (BMS) and outputs information such as an error output when there is no output, output amount, available time, efficiency and input power in a user interface-display device. The present invention provides the input/output control apparatus of an energy storage system comprising: a charger (100) for converting AC power into DC power; an inverter (500) for converting the DC power into the AC power and outputting the AC power; and a battery pack (400) including a battery module (420) for charging the DC power from the charger (100) and discharging the charged DC power via the inverter (500), an input/output check circuit part (430) for outputting error output information when there is no output, output amount, available time, efficiency and input power of the battery module (420), and a battery management system (410) for outputting output information from the input/output check circuit part (430) to a display part (300).
