Abstract
Disclosed herein is an apparatus for updating charging/discharging efficiency factors of an energy storage system. The apparatus includes: a correlation coefficient calculate unit configured to calculate correlation coefficients between n charging/discharging reference values input to the energy storage system during a predetermined update cycle and (n+k) charging/discharging power values measured in the energy storage system after the predetermined update cycle has started, where n and k are natural numbers; a selection unit configured to select n charging/discharging power values corresponding to the n charging/discharging reference values among the (n+k) charging/discharging power values based on correlation coefficients; and an update unit configured to update the charging/discharging efficiency factors set for each power range with n charging/discharging efficiency factors calculated by using the n charging/discharging reference values and the selected n charging/discharging power values.
