Abstract
There are provided an energy storage system and a method for driving the energy storage system, which can exactly measure discharge current by calculating measurement times of the discharge current according to the frequency of the discharge current. An energy storage system includes a battery rack, a battery management system configured to control charging and discharging of the battery rack, and a power conversion system configured to supply discharge current of the battery rack as an alternating current having a frequency to the battery management system. The battery management system is further configured to calculate measurement times of the discharge current, measure the discharge current at the calculated measurement times, and control the charging and discharging of the battery rack based on the measured discharge currents.
