In a study by Javani et al. [ 103 ], an exergy analysis of a coupled liquid-cooled and PCM cooling system demonstrated that increasing the PCM mass fraction from 65 % to 80 % elevated the Coefficient of Performance ( COP) and exergy efficiency from 2.78 to 2.85 and from 19.9 % to 21 %, respectively.
This new cooling strategy improved the temperature inhomogeneity by reducing the temperature uniformity between cells by 3.2 C and by reducing the consumed cooling flow by 38 %. Shi et al. [35] investigated the effect of setting the air inlet on the side wall of the battery pack to the internal temperature field.
The range of PCM melting temperature for cooling applications lies in the thermal comfort range of 20–28 C in the case when thermal comfort and stratification effect reduction is targeted. This range increases to 30–50 C if …
