Investigation on Thermophysical Characterization of Nano Composite Phase Change Materials for Battery Cooling in EV 2022-28-0420

Nano Enhanced Phase Change Material (PCM) is proposed as Battery Thermal Management System. by nature, the pure paraffin has low thermal conductivity and sub-cooling characteristics. In order to increase the thermal conductivity of PCM, thermal conductive substance such as nanoparticles are added to PCM, SiO2 nanoparticles were dispersed into paraffin wax tosynthesisSiO2 –PCM nanocomposites. The chemical, physical and thermal properties of CPCMs were determined by various material characteristic techniques. The TGA and DTG results show that all CPCMs have good thermal and chemical stability. With the addition of SiO2 improved the thermal and chemical stability of pure paraffin The latent–heat of fusion was decreased with increasing the loading of SiO2 and also the thermal conductivities of CPCM increased.
