Abstract

Alternative energy has many innovations, especially electrical energy for electric boats, which can increase efficiency and reduce the levels of gas emissions from the performance of the machines. The battery can be an alternative to the electrical power source, usually used as a Lithium-Ion (Li-Ion) battery. In developing Li-Ion battery performance, the Battery Thermal Management System or BTMS can be used to reduce the impact of overheating when the battery is discharged. The method of BTMS is usually effective it was the immersion method using the coolant, and one of the coolant was PCM. This thesis will discuss and analyze the thermal performance of the Lithium-Ion Phosphate (LiFePO4) battery pack within the immersion cooling method using PCM paraffin C₂₂-C₄₅. The variation in this research was 90% immersion, 50% immersion, and 30% immersion with an inclination of degrees 15º and 35º for the Rolling (x-axis) and Pitching (z-axis) condition for each variation of immersion. Based on the simulation results, the temperature performance of the battery pack was in the range of less than 40 ºC. The operational temperature of 90% and 50% immersion can work properly for keeping the temperature performance of the battery pack. However, the 30% immersion cannot work properly the battery pack temperature performance. The effect of inclination degree variation, 15º and 35º with Rolling (x-axis) and Pitching (z-axis) had different values. For the effect of inclination degree can be conclude that, 15º condition the temperature will be more colder than the 35º condition. On the Rolling, the temperature distribution was spread evenly for each battery. Meanwhile, on the Pitching, the temperature distribution has a different value for each battery cell, which is caused by uneven distribution.
