The International Maritime Organization has recently strengthened the regulation of air pollutants, and battery-powered eco-friendly electric propulsion vessels have drawn attention. An electric ship"s main power unit is an energy storage system (i.e., batteries). For propulsion, attempts have been made to use lithium-ion batteries with high energy densities as secondary power sources. Unfortunately, these batteries present a higher risk of explosion than primary lead-based batteries. In recent years, electrochemical impedance spectroscopy, which measures the impedance of a battery and predicts its lifetime, has been widely used to mitigate this risk. Extant EIS equipment is large and expensive, however. Thus, it is inefficient and uses push-pull circuitry, resulting in distorted output voltages. In this paper, we fabricate an EIS impedance measurement module that minimizes this distortion and measure the impedance parameters of a battery when charging and discharging. Then, we analyze the battery’s aging and lifetime.
