The electric vehicle showcases a promising development in the future. Recently, the most reliable power storage for such a system is a Li-ion battery. The performance of this battery, however, relies on the thermal management system implemented on the vehicle. Albeit having a sufficient performance for the current state of an electric vehicle, enhancement is necessary to make sure that the future requirement is within the remit of the cooling system. One of the simple but powerful enhancements is by employing a mini-channel cold plate. In this study, the performance of a serpentine minichannel cold plate in various Reynolds numbers (Re) was investigated experimentally. The results illustrate a better mean of cooling of high Re flow, indicated by the lower surface temperature and higher heat transfer coefficient up to 2.1 W/m2∙K. Additionally, the performance was then compared to the pressure drop to represent the efficiency of the pumping power requirement of such a system. The highest h/∆P is observed at Re = 2130.33 which correspond to the mass flow rate of 0.5 LPM. It was found that although having a higher heat transfer coefficient, the efficiency is much lower due to pressure drop rise as the mass flow rate increases
