Abstract: A load area tracking type ship battery management system is proposed. The ship battery management system includes a calculation unit for generating SFOC curve data periodically by calculating specific fuel oil consumption (SFOC) versus ship load factors, a LF setting unit for specifying a ship load factor point as a light load factor (LF) point in the SFOC curve data, a HF setting unit for specifying a ship load factor point as a heavy load factor (HF) point, a Emax setting unit configured to obtain a highest point (Emax) of generator efficiency, a Rmin setting unit for calculating battery charging efficiency in the LF to obtain a smallest load factor point (Rmin) bearing a generator load by battery charging, and a Rmax setting unit for calculating battery charging efficiency in the HF to obtain a highest load factor point (Rmax) bearing the generator load by battery discharging.
