Abstract: A novel hybrid battery thermal management system comprising of liquid cooling, and phase change material is proposed for pouch cell lithium ion battery. This system integrates with cold plates grooved with converging twisted serpentine mini-channel (CTSC) through which Al2O3–Cu/water hybrid nanofluid passes through. The effects of different channel cross-sections viz. Square, ellipse, slot, hexagon and kite, mass flow rate (m˙) and volume fraction of nanofluid on the maximum temperature (Tmax), temperature uniformity (ΔT) are studied. The results indicate that hybrid cooling keeps the module temperature below the safe limits under a fast discharge rate of 8C. Better cooling performance is observed when cold plates are grooved with CTSC than the uniform serpentine channel. Kite cross-section is observed to keep the Tmax (328.05 K) as well as ΔT (5.65 K) lower than the other cross-sections for the same hydraulic diameter and channel length at m˙ = 0.0005 kg/s and φ = 1% while the lowest pressure drop is found for square cross-section. Tmax of the battery decreases with the increase in m˙ and ΔT of all cells is well below 3.5 K. The dispersion of hybrid nanoparticles of 5% reduces Tmax and ΔT by 6.24 K and 0.69 K, respectively.
