Abstract

Battery is an electrical component which is capable of storing energy in the form of chemical reactions. In the process of receiving (charging) and releasing (discharging) energy, some of the energy can be lost and turned into heat. Excessive heat can impair performance and shorten battery life. Immersion cooling is one of the direct contact cooling methods for Battery Thermal Management Systems (BTMS), where the battery modules are immersed in a pool of dielectric coolant. The present work will discuss the cooling performance of immersion or direct contact method for a battery module by CFD code analysis. The simulated battery model is a Lithium-Ion type with a capacity of 50 Ah, and the coolant used is Novec 7300. The immersion will be varied based on the surface area of the battery module immersed: 100%, 90%, and 50% immersion. From the simulation results, it is found that 100% immersion and 90% immersion can keep the battery temperature below 308.15 K, which is the upper threshold of the safe operating temperature for lithium-ion battery. 100% immersion can keep the average battery temperature at 300.40 K. 90% immersion can keep the average battery temperature at 301.89 K. 50% immersion can keep the battery temperature at 308.40 K.
