The environment has gained significant significance recently, and companies involved in several technology areas are moving in the direction of eco-friendly solutions. One particular of the most talked about topics in the auto field is lithium-ion battery pack packs for electric vehicles and their battery thermal management systems (BTMSs). This work aims to display the most used lithium-ion battery pack cooling methods and technologies with best working temperature ranges together with the best performances. Various cooling methods are shown and discussed, with a concentrate on the comparison among air-cooling systems and liquid-cooling systems. In this context, a BTMS for cylindrical cells is presented, exactly where the cells are organized in staggered lines inlayed in a solid structure and cooled through forced convection within channels. The particular thermal behavior of this BTMS is simulated by using the computational fluid dynamics (CFD) approach. The effect from the geometry of the BTMS for the cell temperature distribution is obtained. It is shown that the use of materials with additives for the solid structure enhances the particular performance of the program, giving lower temperatures to the cells. The program is tested with air-cooling and water-cooling, showing that will the best performances are usually obtained with water-cooling when it comes to cell packing density and lowest cell temperatures.
