Performance Investigation of PCM/Pin Fin Coupled Battery Thermal Management System

The low thermal conductivity of phase-change materials (PCMs) hampers the commercialization PCM cooling battery management systems. Further reduction resistance between and batteries is still a challenging problem. In this study, / pin fin design proposed. ANSYS Fluent was used to construct model design. SIMPLE algorithm second-order upwind scheme were solve momentum energy equations. Compared with traditional pure PCM/plate designs, maximum temperature (Tmax) lower for PCM/pin because heat transport from enhanced owing larger heat-transfer area. Tmax configuration reached 55.76°C after discharge, exceeding upper-limit 55°C. contrast, design, only 53.44°C. This indicates that effectively alleviates accumulation successfully maintains within safe range. effects thickness section area on behavior investigated. It found decrease cross-sectional can significantly reduce Tmax. When 1 mm2, 51.07°C. addition control under 55°C, minimum thicknesses 3.71, 2.89, 2.38 mm PCM, fin, respectively. Thus, compared other in fewer are required, weight modules reduced, density improved.
