Summary:Disclosed herein are the energy storage system (100) of an Uninterruptible Power Supply (UPS) equipped with the battery (30) and a method of driving the same. The energy storage system (100) includes a commercial power source unit (20) configured to supply a first power source to a load (10), the battery (30) configured to supply a second power source to the load (10), a power failure monitoring unit (41) configured to monitor a power failure state in the commercial power source unit (20), a charging/discharging determination unit (42) configured to determine a charging state of the battery (30), and a power source control unit (43) configured to control the commercial power source unit (20) and the battery (30) in response to output of the power failure monitoring unit (41) or the charging/discharging determination unit (42) so that the first power source or the second power source is supplied to the load (10). A power reservation ratio for the use of power can be increased by reducing power used during daytime.
