Transport sector comes under largest energy consuming category, after mining and other industries, a significant fuel economy improvement are required to reduce green house emission. Till now the most promising technologies in this attempt are electric vehicle. Electric vehicles use large batteries to store energy, most common battery used in electric vehicles are lithium ion and lithium polymer preferred due to their high energy density compared to weight. The flow of current causes heating in the battery cells, performance of Lithium-Ion battery cells is greatly impacted by their temperature. For optimum performance it should operate in desired temperature range (15°C-35°C). Battery cooling system is the system which maintain optimum temperature of battery by cooling/heating to increases the thermal efficiency of vehicle. Most common Battery Thermal Management methods used today are, Air Cooled, Indirect liquid Cooled and Direct Cooled.
