The use of Lotus-Type Porous Copper (LTP) Copper in conjunction with liquid heat pipe (LHP) technology has been shown to decrease the average surface temperature of a battery simulator from 93 °C to 65 °C when subjected to a heat generation of 40 W. Vachhani et al. evaluated the viability of a novel dual-evaporator loop heat pipe (DE-LHP) in BTMS. This research
Battery thermal management systems based on heat pipes can be classified into heat pipe only, heat pipe-air cooling, heat pipe-liquid cooling, and heat pipe-PCM. In the last few years, researchers developed a more complex solution by combining three cooling methods such as heap pipe-PCM-liquid cooling to get better thermal performance.
The heat pipe serves to transfer the battery''s heat energy. In other hands, PCM functions as a heat sink when the battery runs, so its performance will stable and extend the lifespan. This study aimed to evaluate the performance of electric vehicle batteries at a temperature of 50 °C using the combination of heat pipe and PCM.
