How does coolant cooling affect battery temperature?

With the coolant cooling system on, the battery temperature decreases first, and then increases when the DOD reaches about 0.55. The reason for this trend is that at the beginning of the discharge the LIBs have endothermic entropic reaction. As the flow rate of coolant increases, the temperature of the battery decreases more.
