Part of the continued research accomplishments of the Air-Conditioning & Refrigeration Engineering Division, a completely new scientific analysis for its Head, Support Prof. Dr. Azher M. Abid continues to be revealed during the Journal of Electrical power Sources. It can be remarkable to note that this journal is classified inside the 1st quarter of Q1 SCOPUS & Clarivate, having an Impact Aspect 9.794.
The analysis is entitled
"3-dimensional numerical examine with the outcome of the air-cooled procedure on thermal administration of the cylindrical lithium-ion battery pack with two unique preparations of battery cells"
With this investigate, a simulation of a few-dimensional battery pack (B-PK) has long been executed, that contains 16 battery cells (BCL) with aligned and non-aligned arrangements. This B-PK continues to be placed in a sq. air duct where by air enters within the top rated with the B-PK and exits from the bottom in the batteries.
This experiment has primarily centered on switching the air velocity (V-AR) that enters the B-PK from 0.03 to 0.09 m/s for three charge/discharge cycles within 2000 seconds.
The effects attained have confirmed that extending the charging/discharging duration of B-PK until the third cycle contributes to an increase in the temperature of B-PK. In truth, the result of changing air velocity has long been most apparent in the second and third cycles of the battery charging course of action. It has also been found that the utmost (T-MX) and average (T-AV) temperatures with the B-PK plus the temperature of the air leaving the battery pack are diminished when the V-AR is greater.
Nonetheless, the review has exposed in addition that the central batteries on the B-PK have a higher temperature, While the batteries during the corners Possess a decreased temperature, According to BCLs Evaluation. Accordingly, it could be concluded that utilization of the aligned arrangement of batteries within the bundle shall lessen the T-AV of the B-PK when put next to an unaligned arrangement of batteries.
