Özet
In this study, the NTGK model was used to evaluate the thermal and electrical analyzes of the battery model and
Taguchi design was implemented to investigate the main effects of four control factors in the battery thermal
management process, those are inlet velocity, mixing ratio, ambient temperature, and C-rate. The Taguchi’s L16
array was fabricated using varying control factors to obtain detailed battery temperature behaviors. As the
discharge rate increased, the temperature value of the model increased, while the temperature value of the model
decreased as the mixing ratio of the nanoparticle increased. As the inlet velocity of the refrigerant increases, the
temperature value taken by the model decreases, while the higher the ambient temperature, the less the increase
in the maximum temperature reached by the model. Also results showed that the most influential factor on both
maximum battery temperature and temperature uniformity responses was the C-rate, while the least effective
factor was the mixing ratio. It was found that an inlet velocity of 0.04 m/s, a mixing ratio of 5, a C-rate of 2, and
an ambient temperature of 283 K will yield the lowest maximum battery temperature. The maximum battery
temperature was 294 K under these conditions. On the other hand, to maximize the temperature uniformity,
0.04 m/s inlet velocity, 3 mixing ratio, 2 C-rate, and 313 K ambient temperature need to be set as processing
parameters. The results showed that the C-rate has to be closely controlled during the discharge process and the
influence of the mixing ratio is negligible. This study can be used as a robust guideline in the design of battery
thermal management systems using nanofluids.
