An Experimental Investigation to Cool Exemplar Lithium-ion Cell using Oscillating Heat Pipe using Blends of Methanol- Diethyl Ethe

Abstract

Today's world has made electric vehicles an imminent need for the hour. Energy performance means that in contrast with internal combustion engine powered vehicles electric vehicles are more energy-efficient. Lithium-ion batteries have been constantly growing in their energy density (gravity energy density) and the cell price per kWh has fallen. Batteries with lithium molecule are seen as appealing to vehicles. Its temperature control system plays an extremely important role in its longevity and performance. Numerous studies of the oscillating heat pipe (OHP) have been performed in order to sustain battery cells under the perfect temperature variation by utilizing various boundaries such as filling proportions, working liquids, pipe diameter, and material of the heat pipe. This work explores the reduction in the operating temperature of such batteries by means of the OHP and the use of methanol- diethylether blends as working material in various mixing ratio(MR) proportions (1:0.25, 1:0.75 and 1:1) to obtain the best performance. The results were also compared with only methanol as working fluid.
