| Abstract |
The commercialization technology of lithium-ion batteries has changed various industrial trends, including e-mobility and shipbuilding industries. In the shipbuilding industry, the ship's electric propulsion system is a system that applies torque and rotational force of an motor to ship's propulsion power, and the capacity of the power system affects ship's operating time and is classified as a major technology. Lithium-ion batteries have many effects in the industry, but they generate heat during the battery charging and discharging process, and the battery temperature is affected by environmental temperature, so a range of controlled temperatures is required. In this paper, the power system of electric propulsion ships is proposed as a module combination, and the maintain temperature range of modules is derived from parallel experiments on temperature and charge and discharge. According to the experimental results, the charging & discharging efficiency and safety of the power supply module can be expected if natural cooling or forced cooling is performed to maintain the temperature of the installation area below 40℃. |
