PURPOSE: A multifunctional uninterruptible power supply system is provided to reduce electric charges by actively coping with a progressive utility rate system. CONSTITUTION: A charging and discharging unit (20) is connected between a power source and a load and includes an AC/DC converter (21) and a DC/AC converter (23). The charging and discharging unit charges or discharges a battery (10). A power measuring unit measures power consumed in the load in real time. A control unit (40) controls the charging and discharging unit.
