In this study, the efficiency of an immersion cooling system for controlling temperature 5S7P battery modules at high charge and discharge C-rates was experimentally evaluated. The study conducted in three main stages including evaluation different coolant oils followed by proposition optimal volume flow rate (VFR) performance under charging/discharging C-rates. first stage, oils, Therminol D-12, Pitherm 150B, BOT 2100, were compared. D-12 achieved superior performance, with highest heat transfer coefficient (HTC) 2171.93 W/m2⋅K ability to maintain maximum (Tmax) difference (∆T) module within safe range. next VFR varied between 0.4 LPM 1.0 selected best oil D-12. 0.8 determined be HTC 2445.73 acceptable pressure drop 12,650 Pa, ensuring a balance energy consumption. Finally, evaluated from 1.5C 3.0C proposed VFR. is effective combination achieve desired extreme C-rate working conditions. maintains Tmax ∆T 38.6 °C 4.3 charging 43.0 5.5 discharging 3.0C.
