Numerical investigation has been performed for the cooling efficiency of Lithium ion battery adopted in electric vehicles. Temperature of Li-ion cell should be controlled under rigorously restricted range for both the very safe from thermal runaway and normal driving of the electric vehicles. The electric cell is heat source during charging and discharging process of it and its temperature could increase up to the pre-assigned limits without proper cooling devices. The present work is looking for efficient cooling system for Li-ion battery which is large heat source for its opertion in EV. Several cooling models are proposed to this research and its performance is revealed for each system. Five cooling models and the reference model from prior work are numerically examined for temperature control of the present Li-ion battery. The present investigation has been carried out with normal driving conditions of electric vehicles presented in market. Consequently, the model with improved outlet geometry shows enhanced cooling performance relative to other suggestions including the reference model which has been adopted in running EVs.
