| dc.description.abstract | Recently, the International Maritime Organization has tightened emission restrictions on greenhouse gases and air pollutants (NOx, SOx, etc.) and has referred to reducing ship carbon emissions. Today, eco-friendly vessels such as hybrid or electric propulsion vessels using large batteries as power sources are being developed to reduce these emissions. Batteries used in hybrid ships continue to be exposed to harmonics. These harmonics affect the battery life. If the condition of the battery is abnormal, the whole system will be affected. To prevent this, estimate the battery's life or health and replace the battery before an accident occurs. In this paper, we propose an EIS (Electrochemical Impedance Spectroscopy) device to estimate the state of a battery. | - |
