Among all battery power alternatives for electric vehicle, lithium-ion battery is the leading candidate. High power density, long cycle life, no memory effect and low auto discharge features are important factors which make it superior. Thermal issues are especially related to Li-ion batteries that can degrade battery performance. Therefore, selecting an appropriate cooling technique for a li-ion battery pack is needed for the commercialization of electric drive vehicles (EDVs). Fostering an ideal cooling control procedure to keep the temperature at an ideal scope of 20°C to 40°C is crucial for extending wellbeing, expanding the pack the board life, and decreasing costs. In this paper, we consider three different types of cell cooling strategy: air cooling, water cooling, nanofluid cooling. Results have revealed that the temperature distributions inside the battery pack can be significantly affected by the coolant type. As compared to air, liquid coolant affects cooling 10-15 times faster. Mass flow rate controls the cell wall temperature of cell in high heat generation.
