ENHANCEMENT OF QUICK CHARGING AND DISCHARGING OF TES SYSTEM BY PCM MIXED WITH AL2O3 NANO PARTICLES FOR EV
ABSTRACT
Technology for storing heat energy with small amount of area has been proposed a challenge to the researchers over the past few decades. This would render highly useful for the thermal management system of electric vehicles. The PCM was used as an energy storage system in this work. It offers the chief advantage of higher storage density which is very much expected for both industrial and domestic needs, especially electric vehicles. In this work, the enhancement of specific heat capacity for the provided PCM was improved by embedding alumina nanoparticles into the storage medium. The addition of nanoparticles in the PCM resulted in the increase of heat absorption capacity, a 50% increase in charging time and a 25% reduction in discharging time of the PCM for the volume concentration of 0.833%. The increase of efficiency by 6% during charging and 4% during the discharging processes were observed as the effect of addition of alumina nanoparticle in the system.
