The electric propulsion ship has been considered an alternative for stricter environmental regulations and safety issues. As electric propulsion ships have been developed, the attention given to a Battery Energy Storage System (BESS) has also grown for green and efficient power supply. However, a BESS-installed ship is still regarded as a non …
