AB  - This paper investigates the working fluid with different flow directions on the battery management cooling system with de-ionized water and ferrofluid 
(0.015%by volume). The pack of batteries with two different coolant directions (Models I, II) used in the present study with sixty Li-ion cylindrical 
cells (25.2V and 30A) are tested under the trickle method for charged process and constant ampere for the discharged process to consider the battery 
module temperature distribution and cooling performance. The uniform temperatures of the battery pack significantly affect the long lifecycle and 
thermal performance. It is found that average temperatures are nearly constant at about 28.5o
C and 29.65o
C for models I and II, respectively. Decreasing 
the maximum temperature of the pack and the temperature gradient across the cell results in the decreasing reverse effect of the cell. In addition, the 
cooling model I gives the temperature gradient across the cell less than those from model II. In addition, the improved thermal physical properties of 
the coolant (Ferrofluid) significantly affect the battery pack decreasing operating temperature, compared with de-ionized water. However, the cooling 
system optimized condition, including the battery module with different operating conditions on a large scale, has been done for more extensive thermal 
performance and a more significant long lifecycle.
